Canadian Tax Bracket Calculator

About

Get a quick, honest answer to 'how much tax will I owe?' without leaving the browser.

This extension calculates Canadian income tax for the current year using official federal brackets combined with your province's brackets. It shows your total tax, after-tax income, effective rate, and marginal rate - plus a per-bracket breakdown so you can see exactly where your money goes.

Use it for:
- Quick sanity-checking your paycheque or take-home estimate
- Comparing how much tax you'd pay if you moved provinces
- Understanding what a raise actually puts in your pocket after the marginal rate kicks in
- Sizing up a freelance contract or side-income gig before accepting

What it does NOT include (yet - those are in Pro):
- CPP/QPP and EI premiums
- Surtaxes (Ontario, PEI)
- Tax credits, deductions, or basic personal amounts
- RRSP, FHSA, or TFSA contribution optimization

The free tier covers the 2026 tax year with full bracket math for every Canadian province and territory. Pro upgrade (one-time $19) adds multi-year comparison (2024-2026), RRSP/FHSA optimization scenarios, capital-gains modelling, and bonus or severance tax planning.

100% client-side: your income data never leaves your browser. No analytics. No telemetry.
