FAQ

Which regime is better?

Roughly, if your total deductions exceed ₹3.75 lakh — the gap between the two standard deductions plus all your old-regime-only deductions — the old regime usually wins. Below that, the new regime's flatter slabs and ₹75,000 standard deduction win.

Can I switch every year?

Salaried individuals: yes — choose at the time of filing each year. Business / professional income: you can switch to the old regime by filing Form 10-IEA, but switching back to new is permitted only once.

Are NPS contributions deductible in the new regime?

Only employer-contribution u/s 80CCD(2) — capped at 14% of salary. Self-contribution u/s 80CCD(1) and 80CCD(1B) are not allowed in the new regime.
