Scope & Assumptions

This article covers Canada, with Ontario and Toronto context, and reflects rules current to 2026. It is written for incorporated Canadian marine repair businesses, boatyards and mobile marine mechanics. Figures marked illustrative are examples, not quotes, and any masked engagement notes end with “Figures changed for privacy.” This is educational information only and not tax or legal advice. Rates and thresholds change, so please confirm the current position before acting.

What Crosses the Year-End Line

1

What Crosses the Year-End Line

The Three Items

Three Things, Three Different Answers
Item at Year EndWhat It IsThe Usual Error
Unbilled work in progressIncome, even though no invoice went outLeft out entirely, understating income
Parts on the shelfAn asset, not an expenseExpensed on purchase, understating income
Customer deposits takenA liability until the work is doneRecorded as revenue, overstating income

Two of these push income down and one pushes it up, which is why a boatyard’s reported profit can be wrong in either direction while every individual transaction looks fine.

Work in Progress Is Income

A boat hauled in November and finished in February straddles the year end. The labour and parts consumed before the year end represent income earned, and business income is computed on the accrual basis: earned when the work is done, not when the invoice is raised or the cheque clears.

Please note this, because it is where guidance most often goes wrong. Business income for a corporation is not a choice between cash and accrual. A marine repair business reports on accrual, and a cash-basis set of books produces a return that does not reflect the year.

  • Value unbilled labour and parts at the year end
  • Tie the figure to open work orders and technician time
  • Keep the supporting schedule, since it is the first thing asked for
  • Reverse it in the following period so nothing is counted twice
Parts Are Inventory Until Used

Parts bought and still on the shelf are inventory, carried at the lower of cost and net realizable value. They become an expense when consumed on a job, through cost of goods sold.

Where stock is genuinely obsolete, a write-down reduces income legitimately. What it needs is a documented basis identifying the specific items and why they cannot be sold, rather than a round figure entered at year end.

Deposits Are a Liability

A deposit taken in autumn for spring work is not revenue. It is money held against work not yet performed, and it sits as a liability until the work is done or the deposit is forfeited.

Seasonal yards take deposits heavily in the shoulder months, which means a busy October can produce a bank balance that looks like a profitable year and is not. Recording deposits as revenue overstates income and pulls tax forward.

Our Actual Experience

A yard can have a strong bank balance in November and a weak year, because half of it is deposits and the other half is work not yet done. Figures changed for privacy.

Risk Warning

Risk Warning: Business income is reported on the accrual basis. Please do not treat cash and accrual as a choice for a marine repair corporation.

Marine Repair Business Taxes: Overview and Key Considerations

2

Overview and Key Considerations

The Framework

What Defines a Marine Repair Business for Tax Purposes

A marine repair business services boats and watercraft: engine work, hull and gelcoat, electronics, rigging, winterization and storage. For tax purposes the defining feature is that revenue comes from labour and parts together, and those two behave differently on margin, on inventory and sometimes on sales tax.

Industry-Specific Tax Challenges
  • Deciding whether costs are current expenses or capital
  • Managing parts inventory across a long off-season
  • Seasonal swings in cash flow and payroll
  • Work that straddles the fiscal year end
  • Deposits taken well ahead of the work
Federal vs. Provincial Tax Responsibilities
ObligationLevelNote
T2 corporate returnFederal, with provincial schedulesOntario is administered with the federal return
GST/HSTFederalOn your CRA return
Provincial sales taxProvincialBC, Saskatchewan, Manitoba and Quebec file separately
Payroll source deductionsFederalProvincial workplace insurance is separate
Workplace safety insuranceProvincialOntario employers register with the WSIB

The last row matters for a yard with seasonal technicians. Workplace safety insurance is a provincial obligation separate from payroll withholding, and it is frequently overlooked when staffing up in spring.

Relevant Legislative Changes Impacting Marine Repairs

Bill C-15 received Royal Assent on 26 March 2026, reinstating the accelerated investment incentive for most depreciable property acquired after 2024 and available for use before 2030. Where it applies, an enhanced first-year deduction replaces the ordinary half-year rule, which matters on lifts, compressors and yard equipment.

Ontario’s corporate small business rate also moves to 2.2% from 1 July 2026, changing the combined rate on active business income.

Income Tax Basics

An incorporated yard files a T2 within six months of its fiscal year end. Payment is due earlier: generally three months for an eligible Canadian-controlled private corporation and two months for other corporations.

Those are different dates and they catch corporations out every year. Diarise them separately.

Payroll Taxes

Withhold income tax, Canada Pension Plan contributions and Employment Insurance premiums, and remit by the deadline for your remitter type. A regular remitter pays by the 15th of the following month.

The remitter type changes as average monthly withholdings grow, so a yard that staffs up materially can move to a more frequent schedule without noticing. Amounts withheld are held in trust, and directors can be assessed personally for amounts not remitted.

Corporate vs. Sole Proprietorship Obligations

Incorporation creates a separate legal entity filing its own return, with liability separation and a lower rate on active income retained in the company. A sole proprietor reports on their personal return and carries the liability personally.

Two practical differences for a marine business. A corporation does not prorate home premises costs by area the way a proprietor does; it uses a proper arrangement or reimbursement. And where the corporation owns a service vehicle, it claims the costs in full and reports a taxable benefit rather than applying a business-use percentage.

Charging GST/HST on Marine Repair Services

Repair labour and parts are generally taxable. Register once taxable sales exceed $30,000 over four consecutive calendar quarters, or in a single calendar quarter.

Please note the single-quarter test, which most guidance omits. A yard can cross $30,000 in one busy spring quarter, long before four quarters have passed. Our page on GST/HST registration covers the mechanics.

Where the customer is a non-resident, some supplies can be zero-rated, and repair services performed on goods that are then exported have their own conditions. Zero-rated is not exempt: credits on related costs remain fully recoverable, so a yard doing significant non-resident work should confirm its position rather than assume tax applies.

Input Tax Credits for Marine Businesses

Registered businesses recover tax paid on tools, equipment, shop supplies, rent and utilities. Each claim needs an invoice carrying the prescribed information, and above a modest threshold that includes the supplier’s registration number.

That single line is where most denied claims originate, and counter receipts from smaller suppliers are where it goes missing. Our guide to input tax credits in Canada sets out the full requirements.

Understanding Capital Cost Allowance (CCA) for Marine Repair Equipment
AssetTypical ClassRate
Travel lifts, hoists, compressors, weldersClass 820%
Forklifts and yard vehiclesClass 1030%
Passenger vehiclesClass 10.130%, with a cost cap
Computers and systems softwareClass 5055%
Application software, tools under $500Class 12100%
Leasehold improvements, including dock work on leased sitesClass 13Over the lease term
Buildings you ownClass 14%

A correction on forklifts. Guidance circulating on this topic assigns forklifts to Class 10 at 30% in one place, Class 53 at 30% in another and Class 53 at 40% in a third. Class 53 is manufacturing and processing machinery, which a repair yard forklift is not, and its rate was never 30% or 40%. A forklift used around a yard is ordinarily Class 10.

Two further corrections. Class 43 is manufacturing and processing equipment, so dock structures do not belong there. Dock work on a leased marina site is generally Class 13; a structure on land you own is assessed on its own facts. And a service truck is either outside the passenger vehicle definition, in which case it is Class 10 with no cost cap, or it is a passenger vehicle in Class 10.1 with the cap. It cannot “qualify fully” in Class 10.1, since the cap is the point of that class.

Our Actual Experience

Three different articles gave three different classes for the same forklift. The class decides the rate, so getting it wrong costs every year the asset is held. Figures changed for privacy.

Key Stat

Key Stat: Class 53 is manufacturing and processing machinery. Please do not put a yard forklift there; Class 10 is the ordinary answer.

Setting Up Marine Repair Business Accounting Systems

3

Accounting Systems and Bookkeeping

The Setup

Choosing the Right Accounting Method

Business income is computed on the accrual basis: income when earned, expenses when incurred. That is the requirement rather than a preference, and it is what makes work in progress reportable at the year end.

Cash-basis reporting is available only to specific activities such as farming and fishing. A marine repair corporation does not have that option, and guidance presenting cash and accrual as a choice is describing a rule that does not apply here.

Setting Up Chart of Accounts for Marine Repair Operations
Account TypeWhat It Covers
Revenue – LabourBillable technician hours
Revenue – PartsParts sold, at the price charged
Revenue – Hauling and launchLift and travel charges
Revenue – WinterizationSeasonal service work
Revenue – StorageYard and indoor storage charges
Revenue – SubletWork sent out, recorded gross
Expense – Labour wagesTechnician pay and burden
Expense – Parts purchasedFeeding cost of goods sold
Expense – Shop suppliesLubricants, abrasives, consumables
Expense – Marina rent or leaseYard and premises
Expense – Utilities and insuranceOperating overhead
Expense – Disposal fees and advertisingWaste handling and marketing
Capital purchasesAnything over the threshold, so it reaches the register
Liability – Customer depositsHeld until the work is done

The last two rows are added deliberately. A capital purchases account stops equipment landing in shop supplies, which is the most expensive routine error in a yard because it costs the depreciation claim in every year afterwards. A deposits liability account stops advance money being read as revenue.

Daily Transaction Tracking

Record sales, invoices, payroll, deposits and refunds as they happen. Separate labour revenue from parts revenue so margin is visible by department rather than averaged across two different businesses.

Reconciling Accounts Monthly
  • Match bank statements to the ledger every month
  • Compare sales tax collected against what was reported
  • Review payroll remittances against the withholding calculation
  • Check the deposits liability against open work orders
  • Reconcile parts purchases against parts issued to jobs

Monthly reconciliation is what keeps a year-end close manageable in a seasonal business. A twelve-month gap turns a small discrepancy into a reconstruction exercise during the busiest part of the year.

Job Costing for Marine Repair Projects

Job costing assigns technician hours and the associated burden directly to each work order. That gives gross profit by job type, which is what tells you whether a repower is worth more than a gelcoat repair.

Labour burden includes employer contributions and vacation pay accrued but not yet paid. Allocating it properly is what makes the job-level margin real rather than notional.

  • Link timesheets to work orders, not to weeks
  • Allocate burden on hours, consistently
  • Record sublet work gross, with the cost against the job
  • Track unbilled hours, since they become work in progress at year end
Allocating Labour vs. Parts

Separating labour from parts matters for margin analysis and for inventory. Issue parts to jobs as they are used so stock does not accumulate unrecorded, and value what remains at the year end.

A perpetual inventory system tracks parts used against parts purchased, which supports both the cost of goods sold figure and any write-down. Financial statements for a Canadian private company are prepared under ASPE, and where a CPA compiles them the engagement is performed under CSRS 4200.

Managing Digital and Physical Records for Tax Compliance

Keep records for six years from the end of the taxation year they relate to. That is the correct measure; describing it as six years from filing understates the period where a return was filed late.

  • Scanned invoices and work orders in cloud bookkeeping software
  • Signed contracts and estimates, whether captured on paper or digitally
  • Technician timesheets matching the electronic job records
  • Year-end parts counts, signed
  • Secure backups held off-site

Please note that record retention here is a tax requirement rather than a Transport Canada one. Marine regulators have their own obligations, but the six-year rule comes from the tax legislation.

Electronic records are acceptable provided they stay readable and retrievable for the whole period. A system migration that leaves years of attachments unopenable is a retention failure even though the data technically exists. Our bookkeeping and accounting services keep this running through the year.

Our Actual Experience

Yards close their books in the one month they have time, which is January. That works only if the reconciliations happened monthly all season. Figures changed for privacy.

Pro Tip

Pro Tip: Please set a capital purchases account and a deposits liability account in your software. Between them they prevent the two most common misstatements in a yard.

Where boatyards misstate the year: work in progress, parts inventory and customer deposits
Where boatyards misstate the year: the jobs, the parts and the deposits.

Maximizing Tax Deductions and Credits for Marine Repair

4

Deductions, Equipment and Credits

The Claims

Identifying Eligible Marine Repair Business Expenses
  • Rent or lease for yard space
  • Utility bills
  • Insurance payments
  • Fees for disposing of fuel or antifouling waste
  • Tools and consumables used in repairs
  • Safety gear costs
  • Training and certification fees
  • Advertising costs
  • Meal and entertainment expenses, within limits

Expenses must be incurred to earn income and must pass the reasonableness requirement, which is tested on the amount relative to the work rather than on whether the category is deductible. Keep invoices that separate labour from parts, since that split feeds both your margin analysis and any review of the file.

Meals and entertainment are generally limited to 50%. Where a service truck is used personally, that use has to be dealt with, and for a corporation the route is a taxable benefit rather than a reduced claim.

Equipment and Parts Tax Deductions Specific to Marine Repair
Asset TypeClassRateNotes
Travel lifts and hoists820%Declining balance
Welders and compressors820%Declining balance
Forklifts and yard vehicles1030%Not Class 53, which is manufacturing machinery
Computers and systems software5055%Application software is Class 12
Dock work on a leased site13Over the lease termNot Class 43, which is processing equipment
Tools under $50012100%Generally still subject to the half-year rule

Parts consumed on a job are a current cost. Parts remaining at the year end are inventory at the lower of cost and net realizable value. Core charge refunds on returned parts should be tracked separately so they do not distort either figure.

The 2026 Position on Expensing

An important correction. Guidance stating that small-value assets, or equipment under $30,000, can be fully deducted in the year of purchase from 2026 is describing rules that do not exist. There is no such threshold.

What does apply is the accelerated investment incentive, reinstated by Bill C-15 with Royal Assent on 26 March 2026, for most depreciable property acquired after 2024 and available for use before 2030. Where it applies, an enhanced first-year deduction replaces the ordinary half-year rule.

  • Check purchases made after 2024 against the incentive
  • The test is when the asset became available for use, not the invoice date
  • Returns still within the reassessment period may be worth revisiting
  • Capital cost allowance is a maximum, so claim less in a weak year if that suits

The second point matters in a seasonal trade. A lift bought in December and commissioned in March is available for use in the later year, and that decides which year carries the claim.

Labour Costs and Job Costing Strategies for Tax Efficiency

Labour is the largest cost in most yards, and job costing is what turns it into information. Track billed hours against actual hours to see unbilled work in progress, which is income at the year end whether or not it has been invoiced.

Allocate payroll costs and benefits across jobs on hours. Comparing margin by job type, such as warranty work against commercial contracts, is what supports pricing decisions before the spring rush.

Leveraging SR&ED Tax Credits for Innovation in Marine Repair

Scientific research and experimental development credits are available for genuine technological advancement: developing a new process, resolving a technological uncertainty, or systematic investigation with recorded results.

The qualifying condition matters more than the credit rate. Routine repair work does not qualify, however skilled. Nor does applying an existing technique to a new boat, or improving a process by ordinary trial and adjustment. What qualifies is work addressing a technological uncertainty that could not be resolved by standard practice, documented as it happens.

  • Eligible costs include wages of staff performing the work and materials consumed
  • A CCPC may claim an enhanced refundable federal credit on qualifying expenditure up to a limit
  • Provincial credits may be available in addition
  • Contemporaneous documentation is what supports a claim, not a description written afterwards

Please take advice before assuming a project qualifies. A claim built on routine work costs preparation fees and produces a denial, and it draws attention to the file.

Other Canadian Tax Credits Applicable to Marine Repair Operators
CreditWhat It CoversCondition
Apprenticeship Job Creation Tax CreditA portion of eligible apprentice salariesRegistered apprentices in the first two years of an eligible trade
Provincial apprenticeship supportVaries by provinceProgramme dependent
Clean energy equipment incentivesAccelerated write-off on qualifying propertySpecific classes, specific equipment

One correction worth making. Interactive digital media credits are aimed at products developed for sale or licence, not at internal booking or inventory software a marina builds for its own use. A yard should not plan around that credit on the strength of an internal system.

Each credit has its own eligibility and its own documentation. Our corporate tax planning service works through which ones actually apply rather than listing everything that exists.

Our Actual Experience

SR&ED claims in the trades fail on the qualifying condition, not the arithmetic. Skilled work is not the same as technological advancement. Figures changed for privacy.

Risk Warning

Risk Warning: There is no $30,000 immediate expensing rule. Please check the reinstated investment incentive instead for property acquired after 2024.

Understanding GST/HST Reporting for Marine Repair Businesses

5

GST/HST, Records and Deadlines

Compliance

Registration and Filing Frequency

Register once taxable sales exceed $30,000, on either threshold test. Reporting frequency is then assigned by size.

Annual Taxable SuppliesAssigned FrequencyReturn Due
$1.5 million or lessAnnuallyGenerally three months after the year end
Over $1.5M up to $6MQuarterlyOne month after the period end
Over $6 millionMonthlyOne month after the period end

This table corrects a figure that circulates widely. Guidance saying that businesses under $1.5 million file quarterly and those over file monthly has dropped the annual tier and shifted everything up a level. Most marine repair yards fall in the first row and are assigned annual filing, with the option to elect something more frequent.

Electing quarterly is often worth it for a yard with heavy spring equipment purchases, because credits are recovered sooner rather than sitting until the following year.

Reporting Requirements

Report tax collected less the credits you claim. To claim credits properly:

  • Keep invoices carrying the supplier’s registration number
  • Keep business and personal expenditure separate
  • Claim only the business portion where use is mixed
  • Retain the documentation for the full retention period

Collected tax is held in trust. Set it aside as it arrives, because directors can be assessed personally for amounts not remitted.

Proper Classification of Capital Assets vs. Current Expenses
Work DoneTreatment
Servicing a lift to keep it operatingCurrent expense
Replacing a worn component in the ordinary courseGenerally current
Rebuilding equipment to extend its life materiallyCapital
Adding capability the asset did not haveCapital
Repainting the shopCurrent
Building a new dock or bayCapital

Where the amount is significant, decide deliberately and write the reasoning on the invoice. Reconstructing it eighteen months later is where yards lose the argument.

Maintaining Accurate Financial Statements for Audit Readiness
  • Balance sheet showing assets, liabilities and the deposits held
  • Income statement with labour and parts separated
  • Cash flow statement, which matters in a seasonal trade
  • Work-in-progress schedule supporting the year-end figure
  • Parts inventory listing with the count sheet attached

Organise records by job number. During a review the questions come job by job, and a filing system organised by month makes a straightforward request into a search.

Handling Tax Inquiries and CRA Communication Effectively

Common triggers include cash volumes without matching paperwork, large parts write-downs without support, contractor payments without the required slips, sales that do not reconcile to credits claimed, and personal use of shop assets that has never been reported.

A correction on penalties. Guidance stating that penalties “start at $250” is wrong. The corporate late-filing penalty is 5% of the unpaid tax plus 1% per complete month the return is late, to a maximum of twelve months, with a higher rate on repetition. The $250 figure is a separate penalty for failing to file electronically where required.

The practical consequence differs. A late return with no balance owing generally carries little or no late-filing penalty. A late return on a profitable season carries a serious one.

Interest compounds daily until paid, and only payment reliably stops it. Taxpayer relief is discretionary and reaches back ten years, on grounds such as circumstances beyond your control or CRA delay.

Meeting Regulatory Deadlines and Filing Obligations
Filing TypeDue DateWho It Applies To
T2 Corporate Tax ReturnSix months after fiscal year endAll corporations, including dormant ones
Balance paymentThree months for an eligible CCPC, two for othersCorporations with a balance owing
Instalment paymentsMonthly, or quarterly where the corporation qualifiesCorporations above the threshold
GST/HST returnsBy assigned frequencyRegistered businesses
Payroll source deductions15th of the following month for a regular remitterEmployers
T4 and T4A slipsEnd of FebruaryEmployers and payers

Two points on this table. The balance payment row is often reversed in published versions: three months is the longer window and it applies to eligible CCPCs, while other corporations have two. And corporate instalments default to monthly, with quarterly available only where the corporation meets the conditions.

Our GST/HST filing service and corporate tax filing service cover these together.

Our Actual Experience

Most yards are assigned annual sales tax filing and are told they should be quarterly. Electing quarterly can still be worth it, but for cash flow, not compliance. Figures changed for privacy.

Risk Warning

Risk Warning: Under $1.5 million the assigned frequency is annual, not quarterly. Please confirm your assigned period rather than assuming.

Incorporation, Cash Flow and Working With a Marine Repair Tax Accountant

Structure, Cash Flow and Working With Us

The Engagement

Incorporation vs. Sole Proprietorship: Tax Implications
FactorSole ProprietorshipCorporation
Return filedT1, with a business statementT2
Rate on business incomePersonal graduated ratesSmall business rate on active income
DeferralNone; taxed as earnedAvailable on income retained
LiabilityPersonalSeparated, subject to guarantees
Compliance costLowerHigher, with formal statements

An eligible Canadian-controlled private corporation claims the small business deduction on the first $500,000 of active business income. In Ontario the combined rate on that income has been around 12.2%, and moves lower as the provincial rate drops to 2.2% from 1 July 2026. Personal rates on the top bracket in Ontario reach the low fifties.

The deferral is the real benefit and it is conditional. It applies to income left in the company. Money taken out is taxed in the owner’s hands, so a yard that distributes everything each year gets far less from incorporating than the rate comparison suggests.

Planning Quarterly Tax Instalments and Cash Flow Management

Corporate instalments are based on the prior year, the year before that, or an estimate of the current year, and the basis is a genuine choice for a business whose season varied.

A correction on dates. Corporate instalments are due on the last day of each month, or each quarter where the corporation qualifies for quarterly instalments, measured against its own fiscal year. The 15 March, June, September and December pattern belongs to personal instalments and does not apply to a corporation.

  • Choose the instalment basis deliberately after a weak or strong season
  • Track invoices weekly through the busy months
  • Match payroll to technician schedules rather than to a flat year
  • Time equipment purchases against availability for use
  • Set collected sales tax aside as it arrives
Forecasting Future Expenses and Investment in Equipment

Distinguish maintenance from capital improvement before the invoice is coded. Hull painting on your own equipment is maintenance; installing a new hoist is capital.

Before a significant purchase, weigh the class rate against the asset’s working life, compare lease against buy on total cost rather than monthly payment, and consider whether the reinstated incentive applies. And remember the claim is a maximum, so a purchase in a weak season does not have to be claimed in full that year.

Building a Tax-Efficient Payroll Structure for Staff
  • Withhold income tax, CPP and EI and remit by your remitter deadline
  • Confirm the remitter type as withholdings grow through the season
  • Issue Records of Employment on seasonal layoffs, which are common in this trade
  • Classify technicians correctly as employees or contractors
  • Register for provincial workplace safety insurance where required

Classification is decided on the facts: control over the work, who supplies the tools, chance of profit or loss, and integration. A written agreement calling someone a contractor does not settle it, and misclassification produces reassessments plus the employer contributions never made.

Utilizing Tax Planning to Support Business Growth and Stability
  • Time significant purchases against the availability-for-use test
  • Choose the capital cost allowance claim rather than defaulting to the maximum
  • Use loss carrybacks where a poor season follows profitable ones
  • Review the shareholder loan balance before the year end
  • Plan the deposit position so autumn cash is not mistaken for profit

On carrybacks, a non-capital loss carries back three years and forward twenty. The year you choose to apply it against changes the recovery, so it is a decision rather than a default.

Frequently Asked Questions (FAQs) on Marine Repair Business Taxes Canada

7

Frequently Asked Questions

FAQ

What is the T2 corporate tax filing deadline for marine repair businesses?+

Six months after fiscal year end. Payment is due earlier, generally three months for an eligible CCPC and two months for other corporations.

How often should I file GST/HST returns for my marine repair business?+

By assigned frequency: annual at $1.5 million or less, quarterly above that to $6 million, and monthly above $6 million. Most yards are assigned annual and may elect more frequent filing.

When is the payroll remittance due date for marine repair companies?+

A regular remitter pays by the 15th of the month following the payroll. The remitter type changes as average withholdings grow, so confirm it as you staff up.

What are the main capital cost allowance classes for marine repair assets?+

Travel lifts, hoists, welders and compressors in Class 8 at 20%, forklifts and yard vehicles in Class 10 at 30%, computers in Class 50 at 55%, and leasehold improvements in Class 13 over the lease term.

Are forklifts Class 53?+

No. Class 53 is manufacturing and processing machinery, which a repair yard forklift is not. Class 10 is the ordinary answer for a yard forklift.

Can I claim meals and entertainment expenses in my marine repair business?+

Generally 50% of reasonable amounts related to the business. Keep the receipt and note the purpose and who attended.

What is the per-kilometre allowance rate for service vehicles?+

The CRA sets prescribed rates annually and they are tiered by distance. Use the current year’s figures rather than a rate quoted in an older article.

How long must I keep records for my marine repair business?+

Six years from the end of the taxation year the records relate to, not six years from filing. Electronic records must stay readable for the whole period.

What accounting method applies to recognizing revenue on long-term repairs?+

Business income is computed on the accrual basis. Work performed but unbilled at the year end is income, so a work-in-progress figure is required rather than optional.

How do I handle customer deposits and progress billings correctly?+

A deposit is a liability until the work is performed or it is forfeited. Progress billings recognise revenue as the work is done, supported by the work order record.

What bookkeeping tools help manage parts inventory effectively?+

A perpetual inventory system tracking parts issued to jobs against parts purchased, with a physical count at year end and any write-down documented item by item.

Is there a $30,000 immediate expensing rule from 2026?+

No. That rule does not exist. The measure that applies is the accelerated investment incentive, reinstated by Bill C-15 on 26 March 2026 for property acquired after 2024.

Does routine repair work qualify for SR&ED credits?+

No. Skilled repair work is not technological advancement. A claim needs a technological uncertainty that standard practice could not resolve, with contemporaneous documentation.

Are corporate instalments due on 15 March, June, September and December?+

No. Those are personal instalment dates. Corporate instalments fall on the last day of each month, or each quarter where the corporation qualifies for quarterly instalments.

What is the corporate late-filing penalty?+

5% of the unpaid tax plus 1% per complete month the return is late, to a maximum of twelve, with a higher rate on repetition. There is no flat $250 starting penalty.

Do I still file if my yard was dormant over the winter?+

Yes. A corporation with no activity still has a filing obligation. Dormancy is not an exemption, and the return generally carries little or no penalty since the calculation runs on unpaid tax.

Sixteen questions, and several exist because published guidance on this trade contradicts itself. Check the class before you check the rate. Figures changed for privacy.

Essential Points on Marine Repair Business Accounting & Tax Compliance

8

Essential Points on Compliance

Quick Reference

  • Maintain clear work order structures including mobile call-outs, warranty, insurance jobs, and abandoned boats.
  • Allocate overhead fairly across labour, parts, sublet work, and shop expenses.
  • Use job costing software to track unbilled labour and work-in-progress accurately.
  • Issue T4 and T4A slips timely for employees and contractors.
  • Assess employee vs contractor status carefully to avoid CRA reclassification risks.
  • Follow CSRS 4200 compilation standards when preparing financial statements reported on ASPE.
  • File GST/HST returns on your assigned frequency, considering the quick method where you qualify.
  • Separate personal use taxable benefits properly to avoid unintended taxable income.
  • Manage seasonal payroll with attention to provincial workplace safety insurance obligations.
  • Track core charges, consignment parts, and refundable deposits distinctly in accounting records.
  • Monitor filing deadlines strictly to prevent penalties and interest charges.
  • Keep a topical FAQ and glossary handy for staff training on marine repair tax essentials.
  • Choose a CPA firm with expertise in Toronto and Ontario marine repair businesses.
  • Use taxpayer relief requests judiciously if facing penalties due to unforeseen circumstances.
  • Document customer contracts precisely to support the timing of revenue recognition.
The Year-End Decisions
  • Value unbilled work in progress at the year end, since it is income under accrual reporting.
  • Count parts physically and value them at the lower of cost and net realizable value.
  • Hold customer deposits as a liability until the work is performed or forfeited.
  • Confirm the class before the rate, since the class decides everything after it.
  • Check equipment is available for use before the year end where you want that year’s claim.
  • Choose the capital cost allowance claim rather than defaulting to the maximum.
  • Confirm your assigned sales tax frequency rather than assuming quarterly.
Corrections Worth Carrying
  • Class 53 is manufacturing machinery, not yard forklifts.
  • Class 43 is processing equipment, not dock structures.
  • There is no $30,000 or small-value immediate expensing rule.
  • The corporate late-filing penalty is 5% plus 1% per month, not a flat amount.
  • Corporate instalments follow your fiscal year, not the personal March to December pattern.
  • Records run six years from the end of the year concerned, not from filing.
  • Routine skilled repair work does not qualify for SR&ED.

Businesses We Serve

Industry Expertise

Marine and trade service businesses share the same issues. Here are ten and the usual finding.

BusinessThe Issue That Usually Appears
Boatyards and marine repair shopsWork in progress omitted at the year end
Mobile marine mechanicsService vehicle treatment and personal use
Marinas with storageAutumn deposits recorded as revenue
Yards with parts countersParts expensed on purchase rather than on use
Shops with travel liftsEquipment coded to supplies, never in the register
Anyone with dock structuresPlaced in the wrong class entirely
Seasonal employersRemitter type changed without anyone noticing
Yards using subcontractorsWorker classification untested until reviewed
Businesses under $1.5 millionAssuming quarterly sales tax filing when annual applies
Anyone buying equipmentPost-2024 purchases on the plain half-year rule
  • Boatyards and marine repair shops: Value the open jobs.
  • Mobile marine mechanics: A benefit, not a proration.
  • Marinas with storage: A liability until earned.
  • Yards with parts counters: Issue to jobs, count at year end.
  • Shops with travel lifts: Check the supplies account.
  • Anyone with dock structures: Leased site means Class 13.
  • Seasonal employers: Confirm it each spring.
  • Yards using subcontractors: The facts decide, not the contract.
  • Businesses under $1.5 million: Check your assigned period.
  • Anyone buying equipment: Check the 2026 incentive.
Our Actual Experience

The trade changes the equipment. It does not change the three items that cross the year end, or the fact that two understate income and one overstates it. Figures changed for privacy.

Professional Guidance: How Gondaliya CPA Handles Your Yard

Marine repair businesses get their numbers wrong in a predictable set of ways: leaving unbilled work in progress out of the year end when accrual reporting makes it income, expensing parts on purchase rather than carrying them as inventory until used, recording autumn deposits as revenue when they are a liability until the work is done, assigning yard forklifts to Class 53 which is manufacturing machinery, putting dock structures in Class 43 which is processing equipment, planning around a $30,000 immediate expensing rule that does not exist, assuming quarterly sales tax filing when a yard under $1.5 million is assigned annual, and using personal instalment dates for a corporation. Gondaliya CPA handles yard accounting on a flat annual fee.

We handle what decides the outcome: valuing work in progress against open work orders, counting and valuing parts at the lower of cost and net realizable value, holding deposits as a liability until earned, assigning equipment to the correct classes with availability-for-use timing, applying the reinstated investment incentive to eligible purchases, confirming the assigned sales tax frequency, and testing worker classification before a review does it for you.

Our team starts with your last filed corporate return, your open work orders and your deposits list. Those three change the answer more than anything else. Whatever your yard, you get clear advice and a fixed price before we start.

Quick Answers
  • Work in progress: Income, even unbilled
  • Parts on the shelf: An asset until used
  • Customer deposits: A liability until earned
  • Reporting basis: Accrual, not a choice
  • Yard forklifts: Class 10, not Class 53
  • Dock work on a lease: Class 13, not Class 43
  • Under $1.5 million: Annual sales tax filing
  • Immediate expensing: No $30,000 rule exists
  • Late-filing penalty: 5% plus 1% monthly
  • Instalments: Your fiscal year, not March to December
Who This Is For
  • For: Incorporated Canadian marine repair businesses, boatyards, marinas with service departments and mobile marine mechanics.
  • Not For: A statement of current prescribed rates or vehicle limits, which are set annually and should be confirmed for the year concerned.
People Also Ask
What is work in progress and why does it matter?+

Labour and parts consumed on jobs not yet invoiced at the year end. It is income under accrual reporting, so omitting it understates the year.

Are deposits taxable when received?+

For income tax they are a liability until earned. For sales tax a deposit generally becomes consideration when applied to the price or forfeited.

Should my yard elect quarterly GST/HST filing?+

Often worth it where spring equipment purchases put you in a refund position, since credits are recovered months sooner than under annual filing.

2026 Update

2026 Update — what is current: This article reflects rules current to 2026. The Class 8 rate of 20%, the Class 10 and 10.1 rates of 30%, the Class 50 rate of 55%, the $1.5 million and $6 million GST/HST reporting frequency thresholds, the $30,000 small supplier threshold on both tests, the six-month T2 filing deadline and the six-year record retention requirement are unchanged. Bill C-15 received Royal Assent on 26 March 2026, reinstating the accelerated investment incentive for most depreciable property acquired after 2024 and available for use before 2030, and Ontario\u2019s small business rate moves to 2.2% from 1 July 2026. Please note that business income is computed on the accrual basis and cash reporting is not available to a marine repair corporation, so unbilled work in progress is income at the year end; that Class 53 is manufacturing and processing machinery and a yard forklift belongs in Class 10, while Class 43 is processing equipment and dock work on a leased site belongs in Class 13; that there is no $30,000 or small-value immediate expensing rule and guidance describing one is describing something that does not exist; that a business with annual taxable supplies of $1.5 million or less is assigned annual GST/HST filing rather than quarterly, with more frequent filing available by election; that the corporate late-filing penalty is 5% of unpaid tax plus 1% per complete month rather than a flat $250; that corporate instalments fall on the last day of each month or qualifying quarter of the corporation\u2019s own fiscal year rather than on the personal March, June, September and December pattern; that the balance payment window is three months for an eligible CCPC and two for other corporations; and that record retention runs six years from the end of the taxation year concerned rather than from filing.
