How much to
set aside?
When you’re self-employed, tax isn’t withheld for you. Reserve the right share of each payment and reach April stress-free.
How much to set aside for tax
When you're self-employed, nothing is withheld at source. See the share of each payment to set aside.
Your invoiced income minus your business expenses, over the year.
Optional — to see how much to set aside on this specific amount.
If you owe more than about $1,800 in tax (both federally and in Québec) two years in a row, the CRA and Revenu Québec may require quarterly payments. Setting the money aside ahead of time spares you the nasty surprise.

A separate account is the secret
Open a separate account and transfer the “tax” share into it as soon as you’re paid. The money is never really yours: it’s waiting for Revenu Québec and the CRA. This tool informs you and doesn’t replace an accountant.
Frequently asked questions
What percentage of my self-employed income should I set aside?
It depends on your income, but often 25 to 35% in Québec. Since nothing is withheld at source, you’re responsible for paying the tax yourself (federal and Québec), the QPP (both portions) and the QPIP. The tool calculates the exact percentage based on your expected net business income.
Why does the QPP matter so much?
When you’re self-employed, you pay both the employee AND the employer portion of the Québec Pension Plan — about 12.60% up to $74,600, plus a 2nd contribution above that. That’s double what an employee pays, but half of it is deductible from your tax and this contribution builds your retirement pension.
What are instalment payments?
These are quarterly tax payments the CRA and Revenu Québec can require if your tax balance owing exceeds about $1,800 two years in a row. Instead of paying everything in April, you pay in advance four times a year. Setting money aside from each payment you receive prepares you for exactly this.
Is the result accurate?
It’s an estimate based on Québec’s 2026 parameters, for a resident with no other income and the basic credits. Your other income, credits or deductions (RRSP, expenses) can change the actual amount. This isn’t tax advice — when in doubt, an accountant refines the picture.
