Bootstrapping in Canada means you pay for the business yourself, and the tax system doesn’t care where the money came from. What matters is the structure you pick. Run it as a sole proprietor on $60,000 of net profit in Ontario and you owe about $7,879 in income tax plus $6,724 in CPP. Incorporate, and a small Canadian-controlled private corporation pays about 11.7% on its first $500,000 of active business income for a 2026 calendar year (a blended figure, more on that below).
Does bootstrapping change how you’re taxed?
No. We looked for a CRA page that gives self-funded businesses their own rules and didn’t find one. You get no bonus for skipping investors, and no penalty either. The tax follows the legal form: you as a sole proprietor, or your corporation.
That’s why the first decision is the one with the tax attached. It’s also the one people make in a hurry, usually because a friend said “you should incorporate.” If you want the wider picture first, the guide to self-employed taxes walks through income, CPP and GST in one place.
What does a sole proprietor pay?
Profit from a sole proprietorship is reported on Form T2125 and taxed with your other income at personal rates. You also pay both halves of CPP, the employee share and the employer share. The self-employed tax calculator gives these Ontario results for 2026.
| Net business income | Income tax | CPP, both halves | Left after both |
|---|---|---|---|
| $30,000 | $2,455.03 | $3,153.50 | $24,391.47 |
| $60,000 | $7,879.42 | $6,723.50 | $45,397.08 |
| $100,000 | $19,044.97 | $9,292.90 | $71,662.13 |
Those figures leave out EI and GST/HST, and they start from profit after expenses. So your receipts matter before the calculator does.
Think of Maya, who builds websites from a spare room in Ottawa and clears $60,000 after expenses. The table says she keeps $45,397.08 once income tax and both halves of CPP are paid. That’s about $3,783 a month of take-home, and she has to set the tax aside herself because nobody is withholding it from a paycheque.
What changes if you incorporate?
A Canadian-controlled private corporation gets the small business rate on active business income up to a limit. Federally that’s 9% on the first $500,000, against 15% for the general rate. Ontario’s small business rate was cut from 3.2% to 2.2% on 1 July 2026. For a year ending 31 December 2026 the corporate tax calculator uses a blend of about 2.7%, worked out by days. That blend is our own arithmetic, not a published rate, and a corporation with a different year end will land somewhere else.
On $100,000 of profit the calculator shows $9,000 federal and $2,696 Ontario, so $11,696 in total and $88,304 left inside the company. Without small business status the same profit would carry $26,500. The CRA’s corporation tax rates page confirms the federal 9% and 15% figures.
The catch is that the $88,304 is still the company’s money. Take it out as pay or dividends and you owe personal tax on it as well, which the dividend tax calculator can estimate. Set that against the sole proprietor’s $71,662.13 on the same $100,000 and the corporation looks $16,642 ahead, but only until you pull the cash out. If you need the money to live on, much of that head start disappears.
Incorporating tends to make sense when profit stays in the business for a while, to pay down debt or fund growth. It makes less sense when every dollar goes straight to your kitchen table.
Is taking money out of your own company a loan?
People treat it that way all the time, and it’s where bootstrappers get caught. Under the rules the CRA describes for shareholder loans, an amount you borrow from your corporation is added to your income for that year. The exception is a loan repaid within one year after the end of the corporation’s tax year in which it was made, and only if the repayment isn’t part of a series of loans and repayments.
Borrow in January, repay the day before the deadline, borrow again the next week? That pattern is the one the rule was written to stop.
Mistakes and limits
The small business limit is shared among associated corporations. It also shrinks when taxable capital is between $10 million and $50 million, and when passive investment income passes $50,000. The calculator ignores all of that, and it ignores credits.
Some smaller traps:
- Instalments. If your net tax owing was above $3,000 in 2026 and in 2025 or 2024, the CRA expects payments on 15 March, 15 June, 15 September and 15 December. The tax instalments calculator splits the total.
- GST/HST. You have to register once taxable sales pass $30,000 in a single calendar quarter or over four quarters in a row.
- Records. The CRA asks you to keep them for at least six years.
- Late returns. A flat 5% of what you owe, then 1% more for every whole month, for up to a year of months.
For the 2025 return, self-employed people had until 15 June 2026 to file, but any tax owing was due on 30 April 2026. We couldn’t find published dates for the 2026 return yet, so check the CRA before you plan around them.
We didn’t confirm anything about deducting start-up costs or claiming losses in the early years. That matters for most bootstrapped firms, and CRA guide T4002 is the place to read it.
How we checked the figures
Federal and Ontario rates are the 2026 figures on the CRA‘s tax rates page. CPP figures come from CRA payroll pages. Corporate rates come from the CRA’s corporation tax rates page and its Ontario page. Filing dates, instalment rules, penalties and the shareholder loan rule come from CRA pages, read on 30 September 2026. Rates that change on 1 October 2026 or later aren’t included. No level of government runs or endorses this site.
Frequently asked questions
Is money I put into my own business tax deductible?
We couldn't confirm a CRA rule that makes it deductible on its own. Business expenses reduce profit, and CRA guide T4002 explains what counts.
Do I pay tax on a loan from my corporation?
It's added to your income unless you repay it within one year after the end of the corporation's tax year in which you took it, and it isn't part of a series of loans.
What is the federal small business rate?
It's 9% on the first $500,000 of active business income for a Canadian-controlled private corporation. The general rate is 15%.
When was the 2025 return due for self-employed people?
The filing date was 15 June 2026, but any balance was due on 30 April 2026. We couldn't find 2026 return dates yet.
Do I need to pay tax instalments?
You may if net tax owing is over $3,000 for 2026 and in 2025 or 2024. The dates are 15 March, 15 June, 15 September and 15 December.
