Tax Atlas
Income tax math for the US, UK, India, Canada & Australia.
Free international income tax calculator. Take-home pay, total tax, and bracket breakdown for the US, UK, India, Canada, Australia and more. No signup.
Hey Product Hunt
I'm Muhammed, Head of Digital at Muthoot Finance in India. Tax Atlas started as a personal frustration — I needed to do tax math for the US, UK, and India side-by-side and every calculator I tried was either limited to one country, locked behind a signup, or last updated three tax years ago.
So I built one.
Tax Atlas covers:
🇺🇸 US (TY 2026) — federal brackets, FICA, NIIT
🇬🇧 UK (2026/27) — income tax, NI, personal allowance taper
🇮🇳 India (FY 2026-27) — new regime, Section 87A rebate, marginal relief
🇨🇦 Canada (2026) — federal + Ontario, BPA phase-out, CPP1/CPP2, EI
🇦🇺 Australia (2026-27) — income tax, LITO/LMITO, Medicare Levy + MLS
Free, no signup, no email wall. Take-home pay, total tax, marginal rate, full bracket breakdown.
Every country page is reviewed by a credentialed CPA, Chartered Accountant, or Chartered Tax Adviser in that jurisdiction — the full panel is at https://taxatlas.app/reviewers/.
Compare countries side-by-side at https://taxatlas.app/compare/. Methodology and sources are public at https://taxatlas.app/methodology/.
Tier 2 (New Zealand, Ireland, Singapore, more) ships next. Would love feedback on what's missing, what's wrong, and which country you'd want covered next.
