AFFORDABLE Basement Finishing Contractor Tax Accountant
A basement finishing contractor is really a renovation general contractor, and the subcontracted electricians, plumbers and drywallers you pay on every job put you squarely in T5018 and payroll territory before the profit ever reaches your T2. Cash jobs land you on CRA’s underground-economy list, and holdbacks and progress deposits distort your year-end. That is why you need a basement finishing contractors accountant in Ontario who knows renovation. At Gondaliya CPA, we specialize in job costing and corporate tax planning for basement finishing contractors, putting your tools and trucks in the right CCA class, filing your T5018 slips, and accruing holdbacks and work-in-progress — AFFORDABLE flat-fee support that keeps you CRA-compliant and stops you paying more tax than you owe.
As a renovation business accountant, we work with basement finishing and remodeling contractors, basement apartment and legal second-unit builders, waterproofing and underpinning contractors, and general home-renovation contractors across Ontario, with year-round support rather than a once-a-year scramble. We tell you plainly what you can deduct, what you cannot, and where the real profit sits on each basement after materials and subs.
Let us handle the numbers so you can focus on the work that actually pays you.

Accounting & Tax Services Tailored for Basement Finishing Contractors
Real, practitioner-level CPA expertise for basement finishing and remodeling, basement apartment, waterproofing and general home-renovation contractors across Ontario — built for how a multi-trade renovation business actually runs.
- We prepare your T2 filing for basement finishing contractors with GIFI on Schedule 100, reporting renovation contract revenue on its correct line against the $500,000 small business limit, so CRA’s automated review never flags your renovation corporation for a construction desk audit.
- We claim capital cost allowance on Schedule 8 CCA renovation, placing your power tools and equipment in CCA Class 8 tools at the 20% Class 8 rate, because most basement finishing contractors under-claim this equipment and hand CRA tax they never actually owed.
- We put your work truck renovation CCA in CCA Class 10 vehicles at 30% Class 10 and your small tools under $500 in CCA Class 12 small tools at 100% Class 12, so a CRA equipment review cannot disallow an inflated first-year claim.
- We carry work-in-progress basement and the 10% holdback Construction Act on incomplete basement contracts so revenue matches cost on your T2, because reporting a multi-week basement job as one lump overstates a single year’s profit and invites a CRA reassessment.
- We present holdback receivable on the balance sheet and tie it to your T2 sales figure, so a completed basement awaiting certification is booked as an asset and CRA does not tax your renovation corporation at 12.2% on cash the customer legally retains.
- We build job costing for basement finishing contractors in Knowify renovation job costing so framing and drywall materials, crew labour and subcontractor labour costs post to each basement, because a 5% costing error erases the profit CRA expects your T2 to show.
- We run day-to-day bookkeeping for basement finishing contractors in QuickBooks for basement contractors with Dext receipt capture renovation on every insulation and flooring purchase, so you hold the six years of records CRA requires and a missing slip never costs you a $5,000 reassessment adjustment.
- We track materials markup and waste on each basement in Sage 50 renovation accounting, separating finishing fixtures and waterproofing materials from crew wages, because offcuts and breakage that reach 10% of material cost erode a margin CRA still expects your cost of sales to explain.
- We connect Buildertrend basement renovation to your file so a progress deposit on a basement apartment flows in as a customer deposit rather than as revenue CRA would tax too early, deferring tax on a $25,000 deposit until the work is earned.
- We reconcile bank and equipment-loan accounts monthly in Xero for renovation contractors and run payroll for basement finishing contractors through Wagepoint, remitting the PD7A so a missed source deduction never draws the 10% CRA payroll penalty on your crew wages.
- We set the salary vs dividends renovation contractor mix, paying T4 salary to the $68,500 CPP maximum earnings while the balance flows as dividends against basement finishing income, so the combined tax CRA collects on your tax planning for basement finishing contractors is minimized.
- We protect the section 125 small business deduction so your active renovation income is taxed at the 12.2% Ontario small business rate, watching CRA’s associated-corporation and passive-income rules that grind the small-business limit down and push profit to the general rate.
- We model equipment lease versus buy on a new compressor or concrete mixer and time the purchase before your December 31 year-end, so even the half-year rule’s 50% first-year limit delivers a meaningful ITA 20(1)(a) capital cost allowance and defers tax CRA would otherwise collect.
- We time your hand tools under $500 purchases so drills, levels and pry bars are fully expensed at 100% in Class 12 the year you buy them, answering can basement contractors write off tools by saving tax immediately instead of depreciating the cost slowly.
- We plan years ahead so your shares qualify for the $1.25M lifetime capital gains exemption, purifying the renovation corporation of non-active assets and watching the section 84.1 anti-surplus rule, so a future sale is tax-deferred and a buyer’s purchase escapes CRA tax.
- We handle the catch-up corporate tax return for basement finishing contractors, reconstructing unfiled T2 revenue and costs from bank deposits and job records where no bookkeeping exists, so CRA cannot arbitrarily assess your renovation business at $10,000 or more above what you actually owe.
- Late filing costs the 5% plus 1% per month late-filing penalty of the balance owing up to twelve months, so we file your oldest unfiled T2 first to stop the penalty compounding and limit the arrears interest CRA charges your renovation company.
- We prepare the unfiled T5018 filing for basement contractors for years you paid subcontracted electrical and subcontracted plumbing trades, filing them with the catch-up returns so CRA does not add the $100 per slip T5018 penalty on top of your late T2.
- We file an RC4288 taxpayer relief request to cancel penalties and interest where illness, a prior bookkeeper’s error or genuine hardship applies, covering the ten years CRA allows and often cancelling 100% of the accumulated penalties on your renovation business.
- We rebuild the undepreciated capital cost pools across the unfiled years so up to $8,000 of missed capital cost allowance on your equipment and work vehicles is recovered across the last three CRA-reassessable years, and recapture on equipment you sold is reported correctly.
- Because basement finishing services are taxable at 13% HST Ontario, we handle your HST filing for basement finishing contractors, set the right tax codes on every invoice, and answer do I charge HST on basement finishing so CRA never assesses tax you should have charged.
- You must register for GST/HST returns for basement contractors once taxable renovation revenue passes the $30,000 HST registration threshold across four consecutive quarters, and we track the exact quarter you cross so CRA cannot assess back-tax on basements where you never collected it.
- We claim the input tax credits on your permit and inspection fees, dumpster and disposal costs, and Class 12 small tools, recovering the HST on line 108 of your GST/HST return, up to $4,000 a year that CRA otherwise keeps if you never claim it.
- Because your input tax credits on materials and subs are large, we compare the regular method against the GST/HST Quick Method renovation filed on Form GST74 each year, checking the $400,000 eligibility limit, and elect whichever remits less HST to CRA and keeps more cash.
- We reconcile the HST on your returns to the sales on your T2 for renovation CRA compliance, because CRA’s matching program compares the two and a basement finishing contractor whose figures disagree by even 2% is among the fastest files selected for audit.
- We file an amended T2 to capitalize power equipment a prior preparer wrongly expensed in a single year, moving it into the correct equipment CCA pool and restoring roughly $3,000 a year of capital cost allowance CRA lets your renovation corporation claim going forward.
- We clean up the shareholder loan and report it on Schedule 50 shareholder loan, because a balance the owner owes past two year-ends is added to personal income by CRA under subsection 15(2), turning a $40,000 draw into taxable income we help you avoid.
- We review whether your regular crew are truly subcontractors under CRA’s rules, because CRA can reassess back CPP, EI and payroll on three prior years of wages that belonged on a T4 — often $15,000 per mislabelled worker — so we fix it and file amended slips.
- We restate prior years where unbilled work and retained holdback were ignored, matching revenue to cost on each basement, so a season’s profit is not double-counted on the T2 and CRA is not taxing your renovation corporation twice on the same $50,000.
- We reclassify subcontracted labour a prior bookkeeper mislabelled and recover the input tax credits on materials expensed without the claim, filing the adjustment before the four-year CRA reassessment window closes and putting a refund that can reach $6,000 back in your renovation business.
- When CRA opens a renovation audit, our CRA audit help for basement contractors manages the whole file and answers the T5018, tool and crew-wage queries inside the deadlines, so a review of one year does not expand into a $20,000 reassessment across three prior years.
- Where CRA proposes penalties for late T5018 statement of contract payments on your subcontracted trades, we assemble the contract-payment records and argue the assessment down or away, saving a basement contractor who pays several trades as much as $3,600 in penalties.
- We resolve WSIB for basement finishing contractors premium reviews by reconciling reported crew wages and subcontractor payments to your T4 summary, because WSIB treats an unregistered subcontracted trade as your worker and can back-charge $9,000 of premiums over the last two years, which we dispute.
- When CRA runs an underground economy CRA renovation review on a cash-heavy basement business, comparing bank deposits to reported renovation income, we prepare the source-and-application-of-funds reconciliation and answer within the 30-day deadline before CRA assesses an unexplained $12,000 gap as income.
- We file the Notice of Objection within 90 days of a CRA reassessment that can add $8,000 in tax and interest, and pursue relief on Form RC4288 where a prior accountant’s error caused the penalties, protecting your right to the Tax Court of Canada.
- We prepare the CSRS 4200 CPA compilation report, the financial statements for basement finishing contractors a bank and a surety require across two fiscal years and tie to your T2, before they release financing on a $60,000 cargo van or equipment package.
- We build the working-capital and equity picture a surety underwrites, presenting amounts retained under the Construction Act and unbilled contract work correctly on the balance sheet and tying them to your T2, so your bonding statements win renovation contracts worth over $750,000.
- Lenders financing a $45,000 equipment package want two fiscal years of compiled statements showing stable margins, so our accounting firm for basement finishing contractors presents your equipment, debt and renovation revenue with the T2 a bank credit desk expects, approving financing faster.
- For prequalification with general contractors, we produce reviewed or audited statements where a compilation is not enough, tying them to your T2 so your renovation company meets the thresholds a $1,000,000 contract and the Construction Act’s 28-day prompt payment Ontario renovation window require.
- The CSRS 4200 report from your CPA for basement finishing contractors discloses no audit or review was performed and sets the accounting basis, tied to your T2 and delivered within 30 days so a $250,000 conditional bond and Construction Act prompt-payment milestones are not lost.
- We handle how to register a renovation business Ontario under the Ontario Business Corporations Act, answering should I incorporate my basement finishing business by capping CRA tax on retained profit below the 53.53% top personal rate and shielding you from a sole proprietorship’s unlimited liability.
- We complete the section 85 rollover renovation on Form T2057, transferring your tools, work vehicle, equipment and goodwill into the new renovation corporation at elected amounts, deferring the capital gain, its 50% inclusion and the recapture a straight sale would trigger for CRA.
- We complete your WSIB registration within the 10-day deadline before the first crew starts and open payroll so the first source-deduction remittance and WSIB premiums renovation are correct, sparing an unregistered contractor the retroactive premiums — often $7,000 or more — that immediate registration avoids.
- As your basement contractor accountant Ontario we open the corporation’s CRA Business Number, register the GST/HST account, and open payroll, closing the old sole-proprietor accounts so you never remit the same renovation income twice or draw a duplicate-filing penalty that can top $1,000.
- We set the opening balance sheet, share classes and first fiscal year-end up to 53 weeks out, so dividends can later be split and the first T2 filing and CRA balance-due date for your renovation corporation — often $5,000 or more — are deferred nearly a year.

Case Studies: Basement Finishing Contractor Accounting & Tax
Toronto Basement Finishing Corporation — Tool & Equipment CCA Reclassified and Tax Optimized
The problem: A Toronto basement finishing corporation had power tools, a compressor, a concrete mixer and a work truck that a prior preparer had dumped into a single wrong CCA class, so the company was under-claiming capital cost allowance every year and expensing thousands in small tools that should have been written off fully in Class 12. Holdbacks and work-in-progress were never accrued, which inflated the profit CRA taxed in a year two large basement contracts closed.
What we did: We rebuilt Schedule 8, moving the power tools, compressor and mixer into Class 8 at 20%, the work truck into Class 10 at 30%, and the small tools under $500 into Class 12 at 100%, filed an amended T2 to recover the missed depreciation, and accrued the 10% holdback and work-in-progress so revenue matched cost.
The result:
- Saved $23,700 in corporate tax in the first corrected year
- Recovered $31,400 of previously unclaimed CCA on tools and equipment
- Smoothed profit so the Small Business Deduction was preserved
Brampton Renovation Contractor — Subcontractor/T5018 & Payroll Fixed, Underground-Economy Review Closed
The problem: A Brampton renovation contractor paid subcontracted electricians, plumbers and drywallers in cash and by e-transfer, filed no T5018 Statement of Contract Payments for three years, and treated a full-time crew as subcontractors — each unfiled slip an exposure to the $100-per-slip penalty and a live subcontractor-versus-employee reassessment risk on CPP, EI and payroll, all while CRA opened an underground-economy review of the cash deposits.
What we did: We rebuilt the books in Sage 50, filed all outstanding T5018 returns, reclassified the true employees onto payroll through Wagepoint with proper PD7A remittances and WSIB coverage, reconciled the bank deposits to reported income, and filed an RC4288 taxpayer relief request on the accumulated penalties.
The result:
- All T5018 penalties cancelled under Form RC4288
- Underground-economy review closed with no additional tax assessed
- Payroll and WSIB brought fully compliant before CRA review
Ottawa Basement Apartment Contractor — Holdback/WIP Accrual & Progress-Deposit Accounting
The problem: An Ottawa basement apartment contractor building legal second-unit conversions was booking every progress deposit as immediate revenue and ignoring the 10% Construction Act holdback, so its financial statements swung wildly and overstated one year’s profit — and its surety had cut the bonding limit, blocking the contractor from tendering on the larger renovation contracts it wanted.
What we did: We restated the books to carry work-in-progress and holdback receivable, accounted for progress deposits as customer liabilities until earned, applied percentage-of-completion on the longer contracts, prepared CSRS 4200 compiled financial statements the surety accepted, and tied the whole file to a clean T2 with GIFI.
The result:
- Saved $17,300 in tax by correcting premature revenue recognition
- Bonding capacity restored and raised for larger renovation tenders
- Financial statements accepted by the surety and the bank
