Quebec salary calculator
Enter a yearly Quebec salary. The result is take-home after a year of the same payroll deductions. Switch the pay frequency to see one 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.
Option 1 annualizes whatever you put in the gross box: A ≈ P × I. With P = 1, I is the salary. This is not a tax-return projection (no RRSP F, no credits beyond TD1 claim codes).
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.
