The salary you offer is not what hiring costs you. On top of gross pay you owe a CPP match and 1.4× the employee's EI premium — and you withhold their deductions each payday, then remit them to CRA on your remitting schedule. Enter the gross pay and see all three views: your true cost, their take-home, and the remittance — split between CRA and Revenu Québec for Quebec. Provinces: Ontario, Alberta, British Columbia, Manitoba, Nova Scotia, Quebec.
Every dollar of gross pay carries statutory employer amounts that never appear on the employee's paycheque: you match their CPP contributions (base CPP and, above the first earnings ceiling, CPP2) dollar for dollar, and you pay 1.4× whatever EI premium they pay. Those amounts are your cost, on top of salary — this calculator shows the total, so you can budget the hire honestly before you make the offer.
The result covers the amounts computed by the published payroll deduction formulas: federal and provincial income tax withholding, CPP (base and CPP2) and EI — the employee side withheld from pay, plus your matching employer CPP and 1.4× employer EI. In Québec the same views use Revenu Québec's formulas instead: QPP (base and QPP2), QPIP, EI at the Québec reduced rate, federal tax after the 16.5% abatement, plus your employer QPIP, the health services fund and the labour-standards (CNT) contribution. It assumes a full-year employee with basic TD1 (and, in Québec, TP-1015.3-V) claims, paid regular wages.
It deliberately excludes costs that have no single published formula, and says so rather than guessing:
Per CRA's Determine if you need to register page: you must register for a payroll (RP) account before your first remittance due date — the 15th day of the month after the month you first withhold deductions. CRA's own example: hire on March 11, first pay March 25 → first remittance due April 15. If you didn't open the account before hiring, you still have to calculate the deductions and remit them on time, or you may be assessed a penalty.
Each payday you withhold the employee amounts; you send them to CRA, together with your employer share, on your remitting schedule. Per CRA's When to remit page: a new employer whose monthly withholding is under $1,000 and who keeps a perfect compliance record remits quarterly (due April 15, July 15, October 15 and January 15). Otherwise a regular remitter (average monthly withholding under $25,000) remits monthly, by the 15th of the following month — for a typical full-time salary, expect the monthly schedule. If a due date lands on a weekend or holiday, the next business day counts as on time. Late remittances draw penalties of 3–10% (20% for repeat gross negligence), so put the dates in your calendar.
The number this tool shows under “what you remit to CRA” is the combined amount for each pay period; multiply by the pay periods in your remitting period when you file.
If you and your hire agreed on a net (take-home) figure — common for nannies and household employees — use the take-home to gross calculator: it works backwards from the agreed net to the gross for the contract and the same cost and remittance views.
Québec hires are supported — and the mechanics differ. QPP replaces CPP, QPIP premiums apply on top, EI runs at Québec's reduced employee rate, and the federal tax withheld is reduced by the 16.5% Québec abatement. Your employer cost also carries Québec-specific levies this tool computes and breaks out: your QPIP premium, the health services fund (FSS) contribution — shown at the 1.65% rate for total payroll of $1,000,000 or less outside the primary/manufacturing and public sectors — and the labour-standards (CNT) contribution. You remit in two places, and the amounts must not be blended:
Registration is also double: per Revenu Québec's registration page, you register for source deductions with Revenu Québec (Register a New Business service or form LM-1-V) and contact CRA to open a payroll program account. You may also have to register with the CNESST — its insurance premium varies by classification and is not included here.
The wages, your CPP match and the 1.4× EI all deduct on line 9060 of your T2125. Our sister site FreelancerTax.ca has the full T2125 line-by-line reference plus free verified calculators for your own self-employment taxes.
All amounts are computed by an open, deterministic engine implementing CRA's T4127 Payroll Deductions Formulas, 123rd edition (effective July 1, 2026) and 122nd edition (January 1, 2026), with rates and constants transcribed from CRA's published pages — never from an AI model's memory. The engine is cross-checked against CRA's own Payroll Deductions Online Calculator (PDOC) and the T4032 deduction tables to the cent before any province ships. Quebec is computed from Revenu Québec's TP-1015.F-V Formulas to Calculate Source Deductions and Contributions (2026-01 version) plus the T4127 Québec variant (K2Q, F5Q, 16.5% abatement), cross-checked against Revenu Québec's own WebRAS calculator. Annual planning math is shown; payroll software running per-period formulas with year-to-date caps may differ by cents.
