How the check works
Employers calculate deductions with CRA's payroll formulas. We use the same 2026 rules: CPP on your pay above the period's share of the $3,500 exemption, CPP2 once your year-to-date pay passes $74,600, EI on insurable pay, and income tax worked out on this pay as if you earned it all year, then divided by your number of pays.
We assume the basic personal claim on your TD1 (claim code 1), which is what most employees have. If you claimed more or less, your tax will differ, and the checker will tell you which way.
Frequently asked questions
How do I know if my paycheque deductions are correct?
Enter your gross pay and the CPP, EI and income tax from your stub. The checker works out what CRA's 2026 payroll rules say should come off and flags anything outside the normal range.
Why is the tax on my pay stub higher than expected?
Common reasons: a bonus or retro pay in this period, extra tax requested on your TD1, a second job, or taxable benefits added to your pay.
Why did CPP or EI stop coming off my pay?
You've probably reached the yearly maximum. In 2026 that's $4,230.45 of CPP (plus up to $416 of CPP2) and $1,123.07 of EI outside Quebec.
What if too much CPP or EI was taken off?
If you had two jobs or changed employers, you may pay more than the yearly maximum. The extra comes back as a refund when you file your tax return.
