Finance Planner Tool computes Indian income tax from figures you enter: salary including perquisites and RSU vesting, house property under sections 23 and 24, capital gains with set-off, business and other income, Chapter VI-A deductions, surcharge, cess and marginal relief.
It is a calculator that shows its working, not tax advice. It has no knowledge of your circumstances beyond what you typed, and a return has to be computed on its own year's law.
