Questions people ask

What is the difference between the old and new tax regimes?

The new regime has lower rates and almost no deductions. The old regime has higher rates and a long list of deductions. Whichever produces less tax wins, and for most taxpayers without a home loan and large 80C investments, that is now the new regime.

What are the current income tax slabs?

Under the new regime: nil up to ₹4 lakh, 5% to ₹8 lakh, 10% to ₹12 lakh, 15% to ₹16 lakh, 20% to ₹20 lakh, 25% to ₹24 lakh, and 30% above that. A section 87A rebate means no tax at all on total income up to ₹12 lakh. A 4% health and education cess applies on top. Budget 2026 left the slabs unchanged, so this table applies both to FY 2025-26 (AY 2026-27), the year being filed for now, and to FY 2026-27 (AY 2027-28).

How do I know which regime is better for me?

Work out the total deductions you can genuinely claim — not the ones you could claim if you rearranged your finances. Compare that against the break-even deduction for your income level. Above the break-even, the old regime wins; below it, the new one does.

Is the standard deduction available in both regimes?

Yes, for salaried taxpayers and pensioners: ₹75,000 under the new regime and ₹50,000 under the old. It is applied automatically and needs no proof.

Can I switch regimes each year?

A salaried taxpayer with no business income can choose afresh every year at the time of filing, regardless of what was declared to the employer. Taxpayers with business or professional income can opt out of the new regime only once, and switching back is then permanent.
