Self employed taxes Canada: what to do now (2026)

If you’re self-employed in Canada, you must report business income on Form T2125, pay personal income tax and Canada Pension Plan (CPP) contributions, and follow CRA rules on instalments and GST/HST registration. Do those first. Then use this guide to claim eligible deductions, avoid instalment surprises, and decide when professional help is worth it.

Here are the immediate steps to take this tax year:

• Register for a Business Number (BN) with the CRA if you haven’t already.
• Determine your GST/HST status: if your taxable revenue exceeds $30,000 over four consecutive calendar quarters, registration is mandatory.
• Track all income and expenses from day one, keeping business and personal finances separate.
• Check whether you owe instalments: if your net tax owing exceeded $3,000 in either of the two previous years, quarterly payments likely apply.
• Set up a simple bookkeeping system before transactions pile up.
• Consider T-Ledgers if you want a CPA to handle filing, bookkeeping, or GST/HST returns on a flat-rate basis.

Key takeaways

Self-employed Canadians must file Form T2125 with their T1 return, pay income tax and CPP contributions, and register for GST/HST once taxable revenues exceed $30,000 over four consecutive calendar quarters.

What taxes do self-employed Canadians actually owe?

Every self-employed person in Canada owes at least two things: personal income tax on net business income and CPP contributions on self-employment earnings. Beyond those, your obligations depend on your situation.

The core obligations are:

• Income tax: calculated on net business income (gross revenue minus allowable deductions) and added to your total personal income on the T1 return.
• CPP contributions: self-employed individuals pay both the employee and employer portions, currently calculated on Schedule 8 of the T1.
• GST/HST: required once you exceed the $30,000 small supplier threshold; optional (but often strategic) below it.
• Payroll remittances: only if you hire employees or pay yourself a salary through a corporation.

One point the CRA stresses: your activity must be carried on for profit to report business income and claim expense deductions. Documenting your profit intent matters, especially in the early years of a new venture.

Provincial income tax adds another layer. Nova Scotia has its own marginal rates that stack on top of federal rates, so your combined rate on the top dollar of income can be significant. Check the Nova Scotia Department of Finance for current provincial brackets, and note that some provinces offer small business credits or deductions that may apply once you incorporate.

Stat to know: Self-employed Canadians pay CPP at roughly double the rate of employees because there is no employer to split the contribution.

How do you report self-employment income and file your return?

Sole proprietors report business income on the T1 personal return using Form T2125 (Statement of Business or Professional Activities). Corporations file a separate T2 corporate return because the corporation is its own legal entity.

For sole proprietors, the process runs like this:

1. Collect gross income for the fiscal year (January 1 to December 31 for most sole proprietors).
2. Complete Form T2125 to calculate net business income after deductions and CCA.
3. Transfer the amounts to lines 13499–14300 of your T1 (gross on 13499/13699/13899/14099, net on 13500/13700/13900/14100/14300 depending on income type).
4. Calculate CPP contributions on Schedule 8 and include them on line 22200.
5. File by June 15 (for self-employed individuals), but pay any balance owing by April 30 to avoid interest.

Key forms to bookmark:

• Form T2125: business and professional income calculation.
• T1 return: your personal income tax return.
• Guide T4002: the CRA’s plain-language reference covering income, expenses, CCA, instalments, and how to complete T2125.

Note that sole proprietors generally must use a December 31 year-end. Choosing a different fiscal year-end requires strict eligibility and reconciliation through Form T1139.

What business expenses can you deduct, and how does CCA work?

You can deduct any reasonable expense incurred to earn business income. Common deductible categories include:

• Office supplies and software used exclusively for business.
• Home office expenses: the portion of rent, utilities, or mortgage interest that reflects your workspace (calculated by square footage or number of rooms).
• Vehicle expenses: business-use portion of fuel, insurance, repairs, and lease payments — requires a mileage log.
• Travel and meals: 50% of eligible meal and entertainment costs; full travel costs when the trip is business-related.
• Professional fees: accounting, legal, and consulting costs paid to earn income.
• Government subsidies and forgivable loans: track these carefully. Subsidies are taxable when received; any forgiven loan portion is taxable in the year it is forgiven.

Capital cost allowance (CCA) applies to assets with a useful life beyond one year: computers, vehicles, equipment. Rather than expensing the full cost in year one, you depreciate the asset over time using CRA’s prescribed classes and rates. Choosing when to claim CCA is strategic — you are not required to claim the maximum each year, so you can defer CCA to a year when your income is higher.

Pro Tip: Keep a contemporaneous mileage log (date, destination, business purpose, kilometres) for every business trip. CRA auditors routinely ask for this, and a reconstructed log created at year-end rarely holds up.

Do you need to make quarterly instalment payments?

If your net tax owing exceeded $3,000 in either of the two previous tax years, you are generally required to make quarterly instalment payments. The four instalment dates are March 15, June 15, September 15, and December 15. CRA typically sends instalment reminder notices showing a calculated amount based on your prior-year taxes.

You have two main options for calculating your instalment amounts:

• Prior-year method: base each payment on one-quarter of last year’s total tax owing. Safe if your income is similar year over year.
• Current-year method: estimate this year’s income and pay one-quarter of the projected balance. Useful if your income has dropped significantly, but requires accurate forecasting.

Missing or underpaying instalments triggers CRA interest charges, compounded daily. Check the 2026 tax deadlines guide from T-Ledgers to keep all your dates in one place.

When do you need to register for GST/HST and get a Business Number?

You must register for GST/HST once your taxable revenues exceed $30,000 over four consecutive calendar quarters. Some businesses, such as taxi and commercial ride-sharing operators, must register regardless of revenue. When you register, CRA assigns a Business Number (BN) if you don’t already have one.

Registration checklist:

1. Legal business name and operating name (if different).
2. Owner’s Social Insurance Number (SIN).
3. Business address and mailing address.
4. Description of your primary business activity.
5. Estimated annual revenue from taxable supplies.
6. Requested effective date of registration.

Voluntary registration is worth considering even below the threshold. Registering lets you claim input tax credits (ITCs) on GST/HST paid for business purchases. The trade-off: you must charge and remit GST/HST on your sales and stay registered for at least one year. If you have significant business expenses or plan a major equipment purchase, voluntary registration often pays off. Time your registration date carefully — the effective date is usually the date of your request.

Pro Tip: If you’re approaching the $30,000 threshold mid-year, register before you cross it. Charging GST/HST late exposes you to penalties and the obligation to remit tax you never collected.

Sole proprietor vs. corporation: which structure fits your situation?

The core trade-off is straightforward. A sole proprietorship is simpler and cheaper to maintain, but all business income flows directly to your personal return and you carry unlimited personal liability. A corporation is a separate legal entity, which means limited liability and the ability to retain earnings at the lower small business corporate tax rate.

Incorporation often makes sense when:

• You consistently retain significant earnings in the business beyond personal living needs.
• You want limited liability protection.
• You qualify for the small business deduction on active business income.
• You plan to bring in investors or sell the business.

Staying as a sole proprietor usually makes more sense when you’re early-stage, your income is modest, or the cost and complexity of corporate compliance would outweigh the tax savings. Read T-Ledgers’ breakdown of incorporating your business pros and cons before making the call.

What record-keeping habits protect you at tax time?

Good bookkeeping means a clear receipt trail, a dedicated business bank account, timely reconciliation, and an organised digital filing system. Most CRA audits of self-employed individuals come down to missing documentation, not disputed income figures.

Common mistakes to avoid:

• Mixing personal and business expenses in the same account — makes every transaction a reconstruction project.
• Missing receipts for meals, travel, or supplies claimed as deductions.
• Poor or absent mileage records for vehicle expense claims.
• Late HST remittances, which attract compounding interest and potential penalties.
• Insufficient payroll setup if you hire employees or family members — CRA expects source deductions from day one.

Paying family members is allowed, but their wages must be reasonable for the work performed and documented like any arm’s-length employee. Subcontractors who meet CRA’s criteria for self-employment status must be issued T4A slips if you pay them $500 or more in a calendar year.

Pro Tip: Reconcile your books monthly, not annually. A 30-minute monthly review catches errors while the transactions are still fresh and eliminates the year-end scramble that leads to missed deductions.

When does hiring an accountant or virtual CFO make sense?

Hire professional help when your time, complexity, or risk exceeds the cost of the fees. Concrete triggers include:

1. You have employees and need payroll remittances set up correctly from the start.
2. You sell into multiple provinces and face varying HST/GST rates or nexus questions.
3. You’re considering incorporation and need a tax-efficient structure from day one.
4. Your revenue has grown quickly and you have no reliable financial statements.
5. You’ve received a CRA review letter or audit notice.

When onboarding an accountant or virtual CFO, bring:

• Prior two years of T1 returns (or T2 if incorporated).
• All business income records and expense receipts for the current year.
• Bank and credit card statements for business accounts.
• GST/HST filing history, if registered.
• A list of assets purchased in the year (for CCA purposes).

A practical note on getting your priorities right

Most self-employed Canadians spend too much time worrying about deductions and not enough time on compliance basics. The order that actually matters is: compliance first, clean records second, tax optimisation third.

Get your T1 and T2125 filed on time, pay your instalments, and remit GST/HST when due. Once those are handled, Guide T4002 is the single best CRA reference for working through deductions and CCA systematically. For anything beyond a straightforward sole proprietorship — payroll, incorporation, multi-provincial sales — an experienced CPA saves more than the fee costs.

Do all self-employed people in Canada have to register for GST/HST?

No. You must register only once your taxable revenues exceed $30,000 over four consecutive calendar quarters. Below that threshold you are a small supplier, though voluntary registration is allowed and gives you access to input tax credits.

When should a self-employed person consider incorporating?

Incorporation tends to make financial sense when you consistently retain significant earnings beyond personal living costs, want limited liability, or plan to access the small business deduction on active business income.
