Self-Employed Tax Guide Canada 2025: CPP, Deductions, and Deadlines

Self-employed Canadians pay both halves of CPP — a total rate of 11.9% on net earnings between $3,500 and $71,300, plus 8% enhanced CPP2 on earnings up to $81,200. The self-employed filing deadline is June 15, 2026, but any balance owing is due April 30, 2026. You must register for GST/HST if your revenue exceeds $30,000 in four consecutive quarters.

Nobody withholds tax from self-employment income — you’re responsible for calculating what you owe, setting it aside, and paying on time. Here’s everything you need to know for the 2025 tax year.

You Pay Both Halves of CPP

This is the single biggest surprise for most new freelancers and sole proprietors. As an employee, you pay 5.95% of your pensionable earnings toward CPP, and your employer matches that amount. When you are self-employed, you are both the employee and the employer. You pay both halves.

That means your total CPP contribution rate is 11.9% on net self-employment earnings between $3,500 and $71,300.

On top of that, the enhanced CPP2 applies at a combined rate of 8% on earnings between $71,300 and $81,200. If your net self-employment income hits $81,200 or above, you are paying the maximum CPP and CPP2 contributions.

The one piece of good news: the employer half of your CPP contribution (5.95%) is deductible against your income. It reduces your taxable income, which lowers the overall hit. The employee half is claimed as a non-refundable tax credit.

EI Is Optional for Self-Employed

Unlike CPP, Employment Insurance is not mandatory when you are self-employed. You can opt in through Service Canada if you want access to EI special benefits, which include maternity, parental, sickness, compassionate care, and family caregiver benefits.

However, opting in does not give you access to regular EI benefits. If your business slows down or you lose a contract, you cannot collect regular employment insurance. Given the cost and the limited coverage, many self-employed Canadians choose not to opt in. It is worth evaluating based on your personal situation — particularly if you are planning to start a family.

Deductible Business Expenses

This is where self-employment starts to work in your favour. Any expense that is reasonable and directly related to earning your business income can typically be deducted. This lowers your net income, which reduces both your income tax and your CPP contributions.

Here are the most common deductions for self-employed Canadians:

• Home office — If you use a dedicated space in your home for business, you can deduct a proportional share of rent or mortgage interest, utilities, property tax, and home insurance. Calculate the percentage based on the square footage of your workspace relative to your total home, or by number of rooms.

• Vehicle expenses — You can deduct the business-use portion of gas, insurance, maintenance, lease payments, or capital cost allowance. Keep a mileage logbook — the CRA requires it, and without one, they can deny your entire vehicle claim on audit.

• Professional fees and subscriptions — Accounting, legal, and consulting fees. Software subscriptions, industry publications, professional association dues.

• Advertising and marketing — Website hosting, domain registration, online ads, business cards, and promotional materials.

• Office supplies and equipment — Supplies can be expensed directly. For equipment under $500, you can generally expense it in full. Items over $500 typically need to be capitalized and depreciated over multiple years using CCA (Capital Cost Allowance) classes.

• Business insurance — Liability insurance, errors and omissions coverage, and other policies related to your work.

• Meals and entertainment — Deductible at 50% of the actual cost when directly related to earning income. Keep receipts and note who you met with and the business purpose.

• Cell phone and internet — The business-use portion. If you use your phone 60% for business, you can deduct 60% of your monthly bill.

The key principle: be reasonable and keep records. If the CRA asks, you need to be able to justify every deduction with documentation.

GST/HST Registration

If your total revenue from taxable supplies exceeds $30,000 in any four consecutive calendar quarters, you must register for a GST/HST account and start collecting tax on your sales. This is not optional past that threshold.

Below $30,000, registration is voluntary. Some self-employed individuals register voluntarily because it allows them to claim input tax credits (ITCs) on the GST/HST they pay on business purchases. Whether this makes sense depends on your expenses and your clients. If most of your clients are businesses that claim their own ITCs, charging GST/HST is a non-issue for them.

Once registered, you will need to file GST/HST returns (annually, quarterly, or monthly depending on your revenue) and remit the net tax collected. Many small businesses use the Quick Method of accounting, which simplifies the calculation significantly.

Filing Deadlines: June 15 Is Not the Whole Story

Self-employed Canadians and their spouses get an extended filing deadline: June 15, 2026 for the 2025 tax year.

But here is the catch that trips people up every year: any balance owing is still due April 30, 2026. The extended deadline only applies to filing the return itself, not to paying what you owe. If you owe tax and pay after April 30, the CRA charges compound daily interest on the outstanding amount, regardless of the June 15 filing extension.

The practical approach: estimate your tax before April 30 and pay what you think you owe, even if you have not finished your return. You can always adjust later. An overpayment will be refunded; a late payment will cost you.

Use our self-employed tax calculator to estimate your balance before the deadline.

Quarterly Tax Installments

If you owe more than $3,000 in net tax for the current year (or either of the two preceding years), the CRA expects you to make quarterly instalment payments. The due dates are:

• March 15
• June 15
• September 15
• December 15

The CRA will send you instalment reminders with suggested amounts, but you are not required to use their figures. You can calculate your own based on your estimated current-year income. If you underpay, you may face instalment interest charges. If you overpay, the CRA applies the excess to your balance.

First-year self-employed individuals typically do not need to worry about instalments until after their first tax return reveals a balance owing above $3,000.

Gig Worker Reporting: CRA Already Knows

Starting with the 2025 tax year, digital platforms including Uber, DoorDash, Etsy, Airbnb, and similar services are required to report your earnings directly to the CRA.

This does not change your tax obligations — gig income has always been taxable. But it does mean the CRA now has an independent record of what you earned. If there is a discrepancy between what the platform reports and what you file, expect to hear from them.

The upside: if you are already reporting your income accurately and tracking your expenses, nothing changes for you. Keep doing what you are doing. If you have been underreporting, now is the time to correct course.

Reducing Your Taxable Income Further

Beyond business expenses, self-employed Canadians have access to the same personal deductions as everyone else. RRSP contributions are particularly powerful for the self-employed because your contribution room is based on your previous year’s earned income, and contributions directly reduce your taxable income. If you had a strong 2024, you may have significant room to contribute and lower your 2025 tax bill.

You can also compare your total tax burden as a self-employed individual against what you would pay as an employee earning the same gross amount. The numbers are often closer than people expect once you factor in deductible expenses. Run both scenarios with our income tax calculator and self-employed tax calculator to see the difference.

FAQ

Do I need to incorporate?

Not necessarily. Many self-employed Canadians operate as sole proprietors for years without incorporating. Incorporation makes sense when your business income consistently exceeds what you need for personal spending — roughly when you are earning over $150,000 to $200,000 and can leave a significant portion inside the corporation to benefit from the small business tax rate (currently 12.2% combined federal-provincial on the first $500,000 of active business income in most provinces). It also provides liability protection. But incorporation adds accounting complexity and cost. For most freelancers and gig workers earning under six figures, a sole proprietorship is simpler and equally tax-efficient.

How much should I set aside for taxes?

A safe starting point is 25% to 30% of your net self-employment income (after deducting business expenses). This covers federal and provincial income tax plus both halves of CPP. If you are in a higher tax bracket or live in a high-tax province, push that closer to 35%. The most reliable way to get an accurate number is to run your actual income and deductions through our self-employed tax calculator — it accounts for CPP, CPP2, federal and provincial rates, and the basic personal amount.
