Federal Paycheque Checker

Plug in your biweekly pay-stub inputs. ACCORD calls its live rules engine to compute what your CPP, EI, federal income tax, PSSA pension, and union dues should be — with the CRA T4127 and PSSA citations on every line. Independent of Phoenix. Independent of Dayforce.

For exact match If you're comparing to a real pay stub, enter your pensionable / insurable earnings (the "Gross Earnings" figure on your stub), not your basic pay. They differ when you have LWOP, leave-with-income-averaging (LIA), non-pensionable allowances, or bilingual bonus adjustments. CPP, EI, and PSSA are calculated on pensionable/insurable earnings — federal income tax is calculated on taxable gross, which may differ again.

Not matching your stub? The three deductions most sensitive to the difference between basic pay and pensionable/insurable earnings are CPP, EI, and PSSA. If any of these diverge by more than a few cents, it's likely because your stub computes them on a different base (after LWOP, LIA, or bilingual-bonus adjustments). Enter your stub's pensionable earnings (not basic pay) above for an exact match. Federal income tax and union dues are less sensitive.
V1 scope: single biweekly period, federal income tax only (no provincial income tax yet), no YTD-aware annual maximums, no retro adjustments, no supplementary benefits or garnishments. The gross input is used as both the pay base and the pensionable/insurable base — real stubs may split these (LWOP, LIA, acting pay). Separate pensionable/insurable inputs coming in V2. Provincial tax modules (starting with Ontario) and YTD-aware calculations are on the roadmap.
