Accounting & Tax Services for Self-Employed Individuals in Canada
Specialized Canadian accounting for self-employed professionals, freelancers, gig workers, and sole proprietors. T2125 reporting, GST/HST, home office and vehicle deductions, CPP planning, and when-to-incorporate analysis.
Self-employment in Canada — most common, often most under-served
Self-employed Canadians report business income on Form T2125 of their T1 personal tax return. The category covers a vast range: freelance designers and writers, independent IT consultants, sole-proprietor tradespeople, real estate agents, mortgage brokers, ride-share and delivery drivers, paramedical practitioners (massage therapists, RMTs, naturopaths), coaches and trainers, and many more. Despite being one of the largest and fastest-growing segments of the Canadian workforce, self-employed taxpayers are also among the most under-served by accounting professionals — many are pushed to DIY software or low-cost tax-time-only services that miss substantial deductions and structural planning.
Form T2125 and what it captures
Form T2125 (Statement of Business or Professional Activities) is the schedule of the T1 General that reports self-employment income and expenses. It includes:
- Gross business or professional income
- Cost of goods sold (for businesses with inventory)
- Business expenses including advertising, insurance, interest, maintenance, office, supplies, professional fees, rent, telephone, utilities, and many others
- Home-office expense calculation (if applicable)
- Vehicle expense calculation with business-use percentage
- Capital cost allowance (CCA) on capital assets including computers, equipment, furniture, and vehicles
- Reconciliation to net business income that flows to line 13500 of the T1
CPP for the self-employed
Self-employed Canadians pay both the employee and employer portions of the Canada Pension Plan — a combined contribution rate that is double the employee-only rate. The combined CPP cost on self-employment net income can easily exceed $7,000 per year at the YMPE ceiling. The cost is real, but the contributions build retirement and disability benefit entitlement. We model CPP cost vs benefit as part of the incorporation decision.
GST/HST registration
Self-employed Canadians whose taxable revenue exceeds $30,000 over four consecutive calendar quarters must register for GST/HST. Voluntary registration before the threshold can be beneficial if business expenses include significant GST/HST that you want to recover as Input Tax Credits. The Quick Method election is particularly valuable for service-based self-employed Canadians with low input costs.
Quarterly tax instalments
Self-employed Canadians who owed more than $3,000 of federal and provincial tax in either of the two preceding years (Quebec: $1,800) are required to pay quarterly tax instalments due March 15, June 15, September 15, and December 15. CRA sends instalment reminders. We calculate the optimal instalment amount using the no-calculation, prior-year, or current-year method (whichever produces the best result) and remind clients of the dates.
Home-office deductions
Self-employed Canadians who use part of their home regularly and exclusively as a place of business can deduct a portion of home expenses including heat, electricity, internet, home insurance, property tax (if owner), rent (if tenant), maintenance, and a CCA-equivalent allocation on the home itself (although CCA on the home is generally not recommended due to principal residence exemption implications). The allocation is based on square footage of business use divided by total home square footage. We optimize the home-office calculation annually.
Vehicle deductions
Vehicle expenses are deductible based on business-use percentage. The calculation requires a detailed kilometre log distinguishing business use from personal use. Allowable expenses include fuel, insurance, registration, maintenance, repairs, lease payments (subject to CRA leasing limits), interest on a vehicle loan (subject to CRA monthly maximums), and CCA on owned vehicles. CRA-imposed limits cap the CCA, lease, and interest deductibility on passenger vehicles. We optimize between leasing and owning, and between personal and corporate ownership where the taxpayer is incorporated.
When should a self-employed person incorporate?
Incorporation generally makes financial sense when:
- Annual net business income exceeds approximately $80,000–$100,000
- The taxpayer can retain meaningful earnings inside the corporation (i.e., does not need to spend every dollar earned to live)
- The business is at low risk of being characterized as a Personal Services Business (PSB) under CRA rules
- The business has lasting potential (incorporation costs aren't recovered if the business closes within 1–2 years)
- Liability protection is genuinely valuable
We model the incorporation decision with actual numbers from the business and provide a clear recommendation.
What Canadian businesses commonly miss about this service
Across the hundreds of Canadian businesses we work with, the same handful of issues come up repeatedly. Many small business owners delay engaging professional accounting until a crisis: a CRA review letter, an unfiled GST/HST return demand, a denied bank loan because financial statements aren't ready, or a Notice of Reassessment that arrived weeks ago. By the time we are first contacted, the cost to fix the problem is often several times what proper ongoing accounting would have cost from the start. Proactive engagement is dramatically cheaper than reactive cleanup.
The Canadian tax landscape also changes constantly. Recent changes that affect most Canadian taxpayers include the 2023 anti-flipping rule (residential real estate sold within 365 days is automatically business income, not capital gain); the Underused Housing Tax (UHT-2900 annual filing requirement for many corporations, partnerships, and trusts holding residential property even when no tax is owing — with $5,000 to $10,000 per-property failure-to-file penalties); the Quebec QST joint registration changes since 2021; the post-2018 Tax on Split Income (TOSI) rules that effectively eliminated casual income splitting through family dividends; the post-2021 $200,000 stock option vesting limit on the 50% deduction for options granted by non-CCPCs; the CSRS 4200 Compilation Engagement standard replacing the older Notice to Reader engagement; and ongoing CRA increased scrutiny on pre-construction assignments, short-term rental businesses, and cash businesses.
How BOMCAS Canada delivers this service
Every engagement begins with a written, fixed-fee engagement letter signed before any work is performed. The engagement letter describes exactly what is in scope, what deliverables you will receive, when those deliverables are due, what your monthly or project fee is, and what (if anything) is outside scope. This eliminates the hourly-billing surprise that most accounting clients fear. The only time we use hourly billing is for genuinely unpredictable items such as CRA audit response or complex one-off projects — and even then we agree to a maximum cap before starting.
Once the engagement letter is signed, you e-sign the CRA authorization (RC59 for businesses or AUT-01 for individuals), and we onboard you to the encrypted client portal with multi-factor authentication. All document exchange flows through the portal — no emailing of sensitive financial documents. Meetings happen by video conference or phone at times that work for you, including outside normal business hours when needed.
Our Canadian tax compliance philosophy
BOMCAS Canada is structured around four operating principles:
- Tell the truth. If a tax position is aggressive, we say so. If a deduction will not survive a CRA review, we say so. If the engagement is going to cost more than originally quoted because the scope changed, we say so before doing the work.
- Bill what we said we would bill. No surprise invoices. No scope-creep billing. If something legitimately changes scope, we discuss it and re-quote before doing the additional work.
- Answer the phone. One-business-day response standard on client communications during normal business hours. No voicemail backlogs.
- Specialize. Canadian tax and accounting is too complex to be a generalist. We do not do US-only tax, UK tax, or any other foreign jurisdiction in isolation. We are Canadian. Our cross-border work is always anchored by deep Canadian compliance.
What ongoing engagement with BOMCAS Canada looks like
For most clients, the ongoing relationship is structured around predictable monthly deliverables. For an incorporated small business client, that typically includes: monthly cloud bookkeeping with full bank and credit card reconciliation; quarterly or annual GST/HST returns prepared and filed; monthly payroll for owner-managers and any employees, with CRA source deduction remittances; year-end Compilation Engagement (CSRS 4200) financial statements; T2 corporate income tax return; owner-manager T1 personal tax return (and spouse where applicable); annual salary-vs-dividend optimization with written recommendation; unlimited email and phone support during business hours; one quarterly check-in call to review numbers and discuss the business; and CRA correspondence handling for routine review letters.
For a personal tax client, the ongoing engagement includes: annual T1 preparation; any required Quebec TP-1 (for Quebec residents); CRA pre-assessment and post-assessment review response when CRA requests additional documentation; Notice of Assessment reconciliation; and proactive tax planning conversations during the year about RRSP, TFSA, and FHSA contributions, major life events (marriage, kids, retirement, real estate), and any planned business or investment changes.

Why Canadian businesses choose specialized accounting over generalist accounting
The Canadian tax and accounting landscape has become significantly more complex over the past decade. The 2018 TOSI rules, the 2021 changes to stock option taxation, the 2022 mandatory reporting changes for trusts, the 2023 anti-flipping rule, the Underused Housing Tax, the changes to the small business deduction phase-out for passive investment income, the new CSRS 4200 Compilation Engagement standard, the continued expansion of digital sales tax rules, and the ongoing post-COVID CRA focus on cash businesses and unreported income have all required accountants to specialize more deeply. A generalist firm trying to cover personal tax, corporate tax, US tax, real estate, trusts, cross-border, and every industry vertical inevitably falls behind on the depth of expertise that any one client needs.
BOMCAS Canada is structured deliberately to maintain depth: we are Canadian-only by design; we work in industries where we have genuine specialized experience; we maintain ongoing professional education in Canadian tax law; we use Canadian-experienced staff at every level; and we coordinate with specialized partners (US-licensed cross-border, legal counsel for corporate restructuring, audit-engagement licensed practitioners) where required rather than trying to handle everything in-house.
