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 and remit their deductions to CRA every pay period. Enter the gross pay and see all three views: your true cost, their take-home, and the remittance. Provinces: Ontario, Alberta, British Columbia, Manitoba, Nova Scotia.
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 CRA's 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. It assumes a full-year employee with basic TD1 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, then send them to CRA together with your employer share. 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.
Not supported: Québec runs its own provincial deductions (QPP, QPIP, provincial tax via Revenu Québec) and a separate Revenu Québec registration, which need their own verified formulas before we'll ship them.
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. Annual planning math is shown; payroll software running per-period formulas with year-to-date caps may differ by cents.
