Hi Product Hunt 👋

I built SmartTaxCalc because Indian tax tools are either behind
signups, riddled with ads, or send your salary data to a server.

SmartTaxCalc is the opposite:
→ 38 calculators covering income tax, NRI/DTAA, capital gains,
  RSUs, HRA, NPS, FIRE, and everyday finance (EMI, SIP, FD, PPF).
→ Every tax formula is reviewed by a practising Chartered Accountant.
→ No account, no login, no tracking of your numbers — all math
  happens in your browser, nothing hits our servers.
→ Completely free.

Most useful for salaried folks comparing Old vs New Regime, and
NRIs figuring out residency, DTAA relief, and property TDS.

Would love your feedback — especially which calculator you'd want
next. Happy to answer any tax-tool questions here!
