Quebec take-home pay
Type an Quebec gross, how often you are paid, and a pay date. Takehome subtracts federal tax, provincial tax, CPP, and EI, and shows what you keep this period.
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.
This is T4127 Option 1 net pay for the pay date, frequency, gross, and claim codes you typed. It recalculates in this browser. No salary figure leaves the device.
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.

docs/jurisdictions.md. Until a Quebec rule set is ingested from Revenu Québec, every Quebec URL on this site is an explanation, not a quiet fallback.
