What this category covers
India's Income-tax Act gives salaried and self-employed taxpayers a choice between the old and new tax regimes, each with different slabs, deductions, and rules. This category covers the moving parts that most affect a typical return: which regime works out cheaper, how HRA exemption is worked out against actual rent and the city you live in, how TDS gets deducted through the year, and when the filing deadlines fall.
Tax slabs, standard deduction amounts, and city classifications for HRA change with Finance Act amendments. The calculators below are kept aligned with the current Income-tax Act figures used across this site — always verify anything return-critical against the current Act or a tax professional before filing.
