Accounting That Understands Architecture Firms
Running an architecture practice means juggling creative projects with complex financial responsibilities. Gondaliya CPA specializes in accounting and tax services for architects and architecture firms, providing affordable, CRA-compliant solutions tailored to your industry. From project-based billing to payroll and consultant payments, we handle the numbers so you can focus on design, delivery, and growing your firm with confidence.
Project-based revenue and long timelines
Architectural projects often span months or years, with retainers, progress billings, and milestone payments. We ensure revenue is recorded correctly and matches project stages.
Mixed staffing models
Architecture firms commonly use employees, contract designers, consultants, and engineers. We help structure payroll, contractor payments, and T4/T4A reporting properly.
Cost tracking by project
Tracking billable vs non-billable hours, reimbursable expenses, and project profitability is critical. We set up systems that clearly show which projects are driving profit.
Professional liability and overhead costs
We account for insurance, software (AutoCAD, Revit), continuing education, and office overhead accurately—maximizing deductible expenses.
Compliance & Tax Considerations for Architects
HST on architectural services
Most architectural services are HST-taxable. We ensure correct charging, collection, and remittance while claiming eligible input tax credits.
Employee vs contractor classification
Misclassifying designers or consultants can lead to CRA penalties. We help assess and structure relationships correctly.
Corporate tax planning
Whether you operate as a sole practitioner or incorporated firm, we plan corporate taxes to reduce liabilities and improve cash flow.

Architecture Firm Accounting & Tax Services
Accounting Services Tailored for Architects & Architecture Firms
Real, practitioner-level CPA expertise for licensed architects, sole practitioners, multi-partner architecture firms, and design-build companies across Ontario — built for how architecture practices bill project fees, manage WIP, and pay subconsultants across long project cycles.
Corporate Tax Filing for Architects & Architecture Firms
- We file your architecture firm T2 return with the WIP election under ITA section 34 so unbilled work-in-progress on long-duration design and construction administration phases is excluded from taxable income until invoiced — a critical election many architecture corporation accountants miss.
- We classify plotting equipment and office furniture under CCA Class 8 at 20%, computers running AutoCAD and Revit under Class 50 at 55%, and leasehold improvements under Class 13 on Schedule 8 of your architecture firm T2 return, ensuring each asset claims the correct depreciation rate.
- We deduct OAA annual membership fees, Certificate of Practice renewal costs, professional liability insurance premiums, and continuing education expenses on your architecture corporation T2 return under the correct GIFI codes — regulatory costs many architects miss when filing.
- Architecture firms paying subconsultant structural engineers, mechanical engineers, or contract architectural technologists must issue T4A slips by February 28 — we prepare all subconsultant T4A summaries alongside your firm's T2 filing to avoid the $25 per day per slip late-filing penalty from CRA.
- We reconcile milestone billing against project completion percentages before filing your architecture firm T2 return, ensuring revenue is recognized in the fiscal year the design phase or construction administration work is performed, not when the client pays the retainer — CRA reassesses firms that report on a cash basis when accrual is required.
Accounting & Bookkeeping for Architects & Architecture Firms
- We set up project-level tracking in QBO for each architectural engagement so your firm's bookkeeping shows retainer deposits, milestone billings, subconsultant costs, and reimbursable expenses per project — giving you gross margin per job instead of a single blended architecture firm number.
- We track work-in-progress by project phase — schematic design, design development, construction documents, construction administration — in your architecture firm bookkeeping so unbilled billable hours are visible in real time and your WIP aging report drives timely invoicing.
- We record intern architect salaries, architectural technologist wages, employer CPP, EI, and WSIB premiums as separate line items in your architecture firm books each pay period so remittance amounts tie exactly to your PD7A filings and year-end T4 summaries.
- We separate subconsultant invoices — structural, mechanical, electrical engineers — from your architecture firm's own revenue in your bookkeeping so pass-through consultant fees do not inflate your reported income and your financial statements show actual architecture service revenue at month-end close.
- We reconcile accounts receivable from developer and institutional clients with 30-day or 60-day payment terms against your architecture firm aging report monthly, flagging overdue project billings before they become bad debts on your firm's books.
Corporate Tax Planning for Architects & Architecture Firms
- We structure your architecture firm owner compensation as a salary-dividend split that keeps active business income under the $500,000 Small Business Deduction threshold, saving your architecture corporation up to 14.3% in combined corporate tax versus the general rate.
- OAA allows non-voting shares in your architecture professional corporation, so we add family members and each can access the $1.25M+ Lifetime Capital Gains Exemption through proper tax planning on a future architecture practice sale or goodwill disposition.
- We time year-end bonus accruals for associate architects and intern architects so the expense is deductible on your architecture firm T2 in the current fiscal year while the employee reports the bonus on their personal T1 in the following calendar year — a standard deferral strategy for firms with December year-ends.
- We calculate quarterly instalment payments for your architecture corporation based on the prior-year method or current-year estimate, whichever is lower, so your firm does not overpay CRA instalments during months between project milestones when no billing is issued.
- We evaluate whether your architecture firm should lease or purchase BIM workstations and plotting equipment based on CCA Class 50 depreciation versus lease deduction limits under ITA section 67.3 — whichever method saves your firm more tax given current-year project income levels.
Catch-Up Corporate Tax Filing for Architects & Architecture Firms
- If your architecture corporation has two or more years of unfiled T2 returns, CRA can revoke your business number and the OAA may flag your Certificate of Practice — we file all outstanding architecture firm corporate returns and negotiate penalty relief before enforcement begins.
- We reconstruct architecture firm revenue from project fee agreements, milestone invoices, and bank deposits when bookkeeping was never completed, building accurate financial statements for each unfiled year so your catch-up T2 returns claim every legitimate subconsultant and overhead deduction.
- CRA charges a late-filing penalty of 5% plus 1% per month up to 12 months on each unfiled architecture corporation T2 return — we apply for penalty relief under Taxpayer Relief provisions using Form RC4288 when project deadlines or staffing transitions caused the filing delay.
- We identify leasehold improvement costs, BIM workstation purchases, and plotting equipment from prior unfiled years and add them to the correct CCA class on each catch-up T2 return so your architecture firm recovers depreciation deductions that would otherwise be permanently lost.
- If CRA issued arbitrary assessments because your architecture corporation never filed, the estimated income is almost always inflated — we replace those numbers with actual project fee invoices, subconsultant costs, and payroll records, reducing the outstanding balance significantly.
GST/HST Filing for Architects & Architecture Firms
- Architectural design fees, construction administration services, and project management billings are HST-taxable at 13% in Ontario — we ensure every architecture firm invoice charges HST correctly and file your corporation's GST/HST return on time to avoid the late-remittance penalty.
- We claim ITCs on all HST paid on AutoCAD and Revit subscriptions, BIM software licences, office rent, professional liability insurance, and subconsultant invoices on your architecture firm GST/HST return — many firms miss ITCs on plotting supplies and continuing education fees that are recoverable.
- Reimbursable expenses your architecture firm bills to clients — printing, courier, travel — are subject to HST if invoiced as part of your taxable supply. We code reimbursable billings correctly on your architecture firm GST/HST return so CRA does not reassess you for uncollected HST on pass-through costs.
- We reconcile HST collected on all project milestone billings and retainer invoices against HST remitted to CRA each filing period so your architecture firm GST/HST return balances exactly — discrepancies on long-cycle project billing are a primary CRA audit trigger for architecture practices.
- Architectural services delivered to clients outside Canada — international design commissions — are zero-rated for HST. We separate your architecture firm's domestic and export project revenue on each GST/HST return so you do not remit HST on zero-rated international design fees.
Corporate Tax Cleanup for Architects & Architecture Firms
- We correct the WIP election under ITA section 34 where your previous accountant failed to exclude unbilled work-in-progress from taxable income on prior architecture firm T2 returns — filing amended returns recovers overpaid corporate tax from years where unbilled design work was incorrectly reported as revenue.
- We reclassify subconsultant payments that were incorrectly processed through payroll on past T4 slips, filing amended T4 summaries and issuing corrected T4A slips to avoid CRA reassessing your architecture corporation for employer CPP and EI on those contract engineers and technologists.
- We rebuild your architecture firm retained earnings schedule from inception by reconciling every prior-year T2 return, dividends declared, and shareholder loan transactions — eliminating balance sheet discrepancies that CRA flags during architecture corporation reviews.
- We correct pass-through subconsultant billing errors where your previous accountant recorded engineer and specialist invoices as architecture firm revenue and expense instead of agent disbursements — this error inflates both revenue and expenses on your architecture corporation T2 returns.
- We correct shareholder loan balances where the architecture firm owner withdrew partner draws without proper documentation, applying ITA section 15(2) rules to determine if amounts must be reported as income or structured as bona fide loans with repayment terms.
CRA Audit Resolution for Architects & Architecture Firms
- CRA audits architecture firms on subconsultant classification — we defend your T4A independent contractor treatment for contract engineers, designers, and technologists using written subconsultant agreements, proof of own-insurance, and control-test documentation that meets CRA guidelines.
- We reconcile every bank deposit against project milestone invoices, retainer payments, and subconsultant reimbursements during a CRA audit, proving that inter-partner transfers, owner contributions, and consultant pass-throughs are not unreported architecture firm revenue.
- We defend the WIP exclusion election on your architecture firm CRA audit by presenting time-entry reports, project phase schedules, and billing milestone documentation — CRA includes unbilled WIP in taxable income when no evidence supports the ITA section 34 election.
- CRA auditors challenge home office deductions for sole practitioner architects — we present your dedicated workspace square footage calculation, lease documents, and utility bills to defend the business-use percentage claimed on your architecture corporation T2 under ITA section 18(12).
- If CRA reassesses your architecture corporation after an audit, we file a Notice of Objection using Form T400A within 90 days and prepare a technical position paper citing ITA sections that support your architecture firm deductions, preventing the reassessed amount from becoming final.
Trust & Estate Tax Returns (T3) for Architects & Architecture Firms
- We prepare T3 trust returns for family trusts that hold non-voting shares in your architecture professional corporation, allocating dividend income to beneficiaries in lower tax brackets — each beneficiary receives a T3 slip and reports their share on their personal T1, reducing total family tax on firm profits.
- We calculate the 21-year deemed disposition on trust-held architecture corporation shares and plan for the tax liability well in advance — failing to address this before the anniversary triggers capital gains tax on the full fair market value of your architecture practice including project pipeline goodwill.
- We ensure T3 trust returns for your architecture firm family trust are filed within 90 days of the trust's year-end — late T3 filing triggers a $25 per day penalty per slip, and CRA compounds interest on any unpaid trust tax from the original due date.
- We structure testamentary trust provisions in estate planning for architecture firm partners so the practice interest flows to a graduated rate estate, accessing the lowest personal tax brackets on architecture firm income earned during the estate administration period.
- We coordinate T3 trust distributions with your architecture corporation's dividend declaration timing so trust beneficiaries receive firm profits in the most tax-efficient calendar year — avoiding bunching dividends into a single high-income year for any one family member.
Incorporation Services for Architects & Architecture Firms
- Ontario architects must incorporate as a Professional Corporation under OAA regulations with a valid Certificate of Practice before billing clients through the corporation — we handle the OAA application, Ontario incorporation filing, and CRA business number registration as a single package.
- We advise licensed architects on the right share structure at incorporation — common shares for the OAA-licensed architect, non-voting shares for family members as permitted by the OAA — so your architecture corporation is set up for income splitting and future practice sale planning from day one.
- We register your newly incorporated architecture firm for WSIB coverage where required, and set up payroll source deductions so your first intern architect and technologist payroll remittance to CRA is filed correctly and on time.
- We help multi-partner architecture firms incorporate a separate holding company above each partner's professional corporation to receive intercorporate dividends tax-free under ITA section 112(1), separating investment assets from the operating firm's professional liability exposure and project claims.
- We prepare your architecture corporation's first-year corporate minute book with articles of incorporation, director resolutions, OAA Certificate of Practice, and share certificates — clients, insurers, and CRA require these documents for project contracts, E&O insurance, and your first T2 filing.

FAQs from Architects & Architecture Firms
Do architects need to charge HST on their services?
Yes, most architectural services in Canada are subject to HST. We ensure that your invoices correctly separate taxable and exempt items, and we help you claim eligible input tax credits to reduce your net HST liability. Proper HST handling also keeps your firm compliant with CRA regulations.
Should my architecture firm be incorporated?
Incorporation can provide significant tax planning benefits, such as income splitting and tax deferral opportunities. We evaluate your firm’s size, revenue, and long-term goals to determine whether incorporation is suitable. Incorporating can also help protect your personal assets and improve your professional credibility.
How should revenue from long-term projects be recorded?
Can Gondaliya CPA work with my current accounting software?
Yes, we integrate with popular platforms like QuickBooks, Xero, Sage, and project-tracking tools used by architects. Our team will optimize your current setup to improve reporting accuracy and compliance. If needed, we also recommend upgrades for smoother bookkeeping workflows.
How do you handle mixed staffing models?
How can I maximize tax deductions for my architecture firm?
We identify all eligible business expenses, including software, professional liability insurance, continuing education, office rent, and project-related costs. By strategically categorizing these expenses, we help reduce taxable income while keeping accurate records. Proper documentation also supports CRA audits or reviews.
How often should my firm review its finances with Gondaliya CPA?
We recommend monthly or quarterly financial reviews to track project profitability, cash flow, and tax obligations. Regular reviews allow proactive adjustments for taxes, expenses, or staffing. This keeps your firm financially healthy and ready for growth opportunities.
