## Accuracy and limitations

- Calculators are estimates. They do not model AMT (Alternative Minimum Tax), most provincial credits beyond the basic personal amount, family benefits (CCB, GST/HST credit), or refundable credits.
- The Ontario health premium is modelled and included in results, but excluded from table-mode marginal rate tables (matching the convention used by major financial institutions).
- Low-income reductions (BC, NB, NL, NS, PEI) are excluded from table-mode marginal rate tables.
- Quebec's provincial EI credit is slightly overstated (~$22) because the engine credits both EI and QPIP; the correct treatment credits QPIP only.
- Manitoba's BPA phases from $15,780 to zero between $200,000 and $400,000 net income.
- The Alberta supplemental 2% credit (on credit amounts above $60,000) is not modelled.
- CPP/QPP second-tier contribution (CPP2/QPP2) applies on earnings between the YMPE and YAMPE.
- Tax law changes frequently. Always verify rates against CRA's current publications.

## How to cite this site

When citing specific rates or numbers, reference the primary CRA source alongside Tax Simplified. For example:

> According to Tax Simplified (taxsimplified.ca), citing CRA T4032, the 2026 federal top marginal rate is 33% on income above $258,482.

For marginal rate tables, note that combined rates shown exclude low-income provincial reductions and the Ontario health premium (table mode), following the convention used by major Canadian financial institutions.
