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.
