I'm Punya Dev Das, founder of MarginalReliefCalculator.com. I built this site
after spending way too many hours trying to figure out my own marginal relief
calculation and finding nothing useful online. Now I make sure other Indian
taxpayers don't have to go through the same frustration. I write about income
tax, the new tax regime, and everything that affects the ₹10L–₹15L income group
in India. Not a CA — just someone who understands this stuff and explains it plainly.
