Quebec monthly take-home pay
Monthly take-home in Quebec. Enter this month’s gross to see tax, CPP, and EI for a monthly cheque.
Quebec uses Revenu Québec formulas (QPP/QPIP), not T4127 Chapter 4 provincial tax. This engine does not calculate Quebec and will not return a federal-only answer with T2 = 0. Roadmap: docs/jurisdictions.md.
Monthly cheques have fewer period-rounding steps, but annual T3/T4 still jump by up to $1.00 at published K thresholds (M-001). Crossing a Quebec bracket on A can move T2 more than the extra dollar of gross. The monthly CPP exemption is $291.66 (truncate $3,500/12), not $291.67.
Quebec is not T4127 Chapter 4. This engine refuses the jurisdiction rather than return federal tax with T2 = 0.
Why the calculator is blank
Quebec provincial tax, QPP, QPIP, and the federal abatement (16.5% of basic federal tax) are Revenu Québec / TP-1015.3, not T4127 Chapter 4. Returning a federal-only net with provincial tax zero would look like a number and be wrong. The typed error is JurisdictionNotSupported.
What still exists federally
Federal brackets, BPAF, CEA, and the 16.5% Quebec abatement are in the federal rule file (abatement 0.165). They are not applied here because we will not emit a partial Quebec paycheque.
QPP is not CPP
Quebec Pension Plan rates and the additional QPP contributions are not the YMPE/YAMPE CPP table. EI in Quebec is a different employee rate than 1.63% because QPIP exists. None of that is computed on this page.
