Self-Employed Tax in Canada

Self-employed Canadians -- sole proprietors, freelancers, and unincorporated partners -- file their business income on the same T1 General return used for employment income, but attach Form T2125 (Statement of Business or Professional Activities) to calculate net profit or loss. That net income is then added to other personal income and taxed at federal and provincial marginal rates. Unlike salaried employees, self-employed individuals bear the full cost of Canada Pension Plan contributions, have no automatic Employment Insurance coverage, and face GST/HST registration once revenue crosses a set threshold. This page summarises the current rules based on Canada Revenue Agency (CRA) published guidance [SC1] and the PwC Canada Tax Summaries [SC2].

How does a self-employed person report business income in Canada?

Business income flows through Form T2125, which calculates gross revenue minus allowable deductions to arrive at net business income. That net figure is transferred to line 13500 (business) or 13700 (professional) of the T1 General. Revenue includes all amounts received or receivable for goods or services in the tax year; the Canadian tax year for individuals is the calendar year (1 January to 31 December). Sole proprietors report 100% of net profit; partners in an unincorporated partnership each report their proportionate share on their own T1. Incorporated businesses operate under the corporate tax regime and are outside this summary. Quebec residents file a separate TP-1 provincial return with Revenu Quebec in addition to the federal T1, and pay QPP (Quebec Pension Plan) contributions rather than CPP [SC1].

Allowable deductions on T2125 include advertising, meals and entertainment at 50% (Income Tax Act s.67.1), vehicle expenses at the business-use proportion, professional fees, office supplies, business insurance, salaries to arm's-length employees, and interest on business loans [SC1]. Capital expenditures are recovered through Capital Cost Allowance (CCA) rather than immediate deduction: common classes include Class 8 (equipment, 20%), Class 10 (vehicles, 30%), and Class 50 (computer hardware, 55%), with the half-year rule applying in the acquisition year. Business-use-of-home expenses -- a proportion of rent, utilities, mortgage interest, property tax, and maintenance -- are deductible via Part 7 of T2125, but the deduction cannot push net business income below zero; any unused portion carries forward indefinitely.

What are the 2025 federal income tax rates that apply to self-employment income?

Federal personal income tax rates for the 2025 tax year, as confirmed by CRA and PwC Canada [SC2]:

The lowest bracket rate was reduced from 15% to 14% effective 1 July 2025 under draft federal legislation; because the change was mid-year, the CRA applies a blended effective rate of 14.5% for the full 2025 tax year and 14% from 2026 onward [SC2]. The federal Basic Personal Amount for 2025 is CAD 16,129, sheltering that amount from federal tax for most filers (the BPA phases down to CAD 14,538 for income above CAD 177,882). Provincial and territorial rates add to these federal rates -- Ontario ranges from 5.05% to 13.16%, British Columbia from 5.06% to 20.5%, Alberta from 10% to 15%, and Quebec from 14% to 25.75% [SC2]. Top combined federal-plus-provincial marginal rates range from roughly 44% in Alberta to 53.5% in British Columbia.

How do Canada Pension Plan contributions work for the self-employed?

Self-employed individuals pay both the employee and employer share of CPP, because there is no separate employer. The combined 2025 rates and ceilings, as announced by the CRA [SC3], are:

• Year's Basic Exemption (YBE): CAD 3,500 -- net self-employment earnings below this amount are exempt from CPP.
• Year's Maximum Pensionable Earnings (YMPE): CAD 71,300 -- the upper limit for base CPP (CPP1) contributions.
• CPP1 rate for self-employed: 11.9% (combined employee 5.95% + employer 5.95%) on net earnings between YBE and YMPE. Maximum CPP1 contribution for 2025: CAD 8,068.20.
• Year's Additional Maximum Pensionable Earnings (YAMPE): CAD 81,200 -- the upper limit for the second-tier CPP2 enhancement, introduced in 2024.
• CPP2 rate for self-employed: 8% (combined employee 4% + employer 4%) on earnings between YMPE and YAMPE (a CAD 9,900 band). Maximum CPP2 contribution for 2025: CAD 792.
• Combined maximum 2025 CPP: CAD 8,068.20 (CPP1) + CAD 792 (CPP2) = CAD 8,860.20.

The tax treatment of CPP contributions for self-employed filers is split: half of the base CPP1 contribution (the employer equivalent, 5.95%) is deductible from income on line 22200 of the T1, reducing taxable income. The other half (the employee equivalent) earns a non-refundable tax credit on line 30800. CPP2 contributions are fully deductible (100%) from income. Employment Insurance (EI) is not mandatory for self-employed individuals; they may opt in voluntarily by registering with Service Canada and paying the employee EI premium rate (CAD 1.64 per CAD 100 of insurable earnings in 2025) via Schedule 13, which then makes them eligible for EI special benefits after a 12-month waiting period [SC4].

When is GST/HST registration required for the self-employed?

Registration under the Excise Tax Act becomes mandatory when total taxable supplies in Canada exceed CAD 30,000 in any single calendar quarter, or in the previous four consecutive calendar quarters combined [SC5]. This is the "small supplier" threshold; below it, registration is voluntary but may be worthwhile so that input tax credits (ITCs) can be recovered on business purchases. Once registration is mandatory, a GST/HST account (Business Number) is issued, and the business begins collecting the applicable rate: 5% GST in Alberta and the four non-participating provinces; 13% HST in Ontario; 15% HST in New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador; and 5% GST plus 9.975% QST (combined 14.975%) in Quebec (administered separately by Revenu Quebec). British Columbia charges 5% GST plus 7% PST (separate provincial registration). Registered businesses file GST/HST returns monthly (over CAD 6 million annual taxable supplies), quarterly (CAD 1.5 million to CAD 6 million), or annually (below CAD 1.5 million). ITCs recover GST/HST paid on business purchases, subject to the 50% restriction on meals and entertainment and capital-cost limits on passenger vehicles.

What are the filing deadlines and instalment requirements for self-employed Canadians?

The T1 General filing deadline for self-employed individuals (and their spouses or common-law partners) is 15 June of the following year -- six weeks later than the 30 April deadline that applies to other filers [SC1]. However, any tax balance owing for the year is still due by 30 April; carrying a balance past that date triggers CRA interest at the prescribed rate from 1 May onward. Late-filing penalties of 5% of unpaid tax plus 1% per full month outstanding (up to 12 months) apply separately and are compounded where the filer was also penalised in a prior year.

Quarterly tax instalments are required where the estimated net tax owing for the current year exceeds CAD 3,000, and the same threshold was also exceeded in either of the two preceding years (CAD 1,800 in Quebec) [SC1]. Instalment due dates are 15 March, 15 June, 15 September, and 15 December (or the next business day where the date falls on a weekend or public holiday). CRA mails instalment reminders calculated under the prior-year method, but filers may choose among three calculation approaches: the prior-year method, the current-year method, or a no-calculation method using CRA's suggested amounts. Failure to pay instalments triggers instalment interest plus a penalty where instalment interest exceeds CAD 1,000.
