Enter your average monthly withholding amount — the income tax, CPP and EI you deduct and remit in a typical month — to see which CRA remitter category you fall into and when each remittance is due. Thresholds reviewed for the 2025 tax year.
Your withholdings
How it works. CRA classifies employers by their average monthly withholding amount — all the income tax, CPP and EI deducted from staff in a month, plus the employer shares. The category sets how often those deductions must be sent in: quarterly for the smallest compliant employers, monthly for most, and up to four times a month for the largest payrolls.

How Small Business Payroll Works
Your remitter category comes from your average monthly withholding amount two calendar years back — the look-back is what lets CRA tell you your schedule before the year starts, and it is why a payroll that grew quickly can still be on a slower schedule for a while. Employers with an AMWA under $3,000 can ask to remit quarterly, but only with a perfect compliance record: every return filed and every remittance on time. Most employers are regular remitters, paying by the 15th of the month after the deductions were made; from $25,000 of AMWA the accelerated schedules take over, splitting each month into two or four remittance periods. Late remittances draw penalties that escalate from 3% to 10% of the amount, so knowing your category is not optional.
Our payroll service runs the remittance calendar for you, and the employee cost calculator shows how the amounts you are remitting fit into the true cost of each hire.
What this calculator does not cover
Quebec runs a separate system: source deductions for Quebec employees — QPP, QPIP and Quebec income tax — are remitted to Revenu Québec on its own schedule, so a payroll with Quebec staff has two calendars to keep. This tool also assumes your AMWA is settled history; if this is your first payroll year, CRA starts you as a regular remitter regardless of size. To set the schedule up correctly from the first hire, see our payroll service.
