Frequently Asked Questions

Which regime should I choose?

If your eligible deductions (80C, 80D, HRA, home loan interest, etc.) are large relative to your income, the old regime often works out cheaper. If you claim few deductions, the new regime's lower slab rates usually win. This calculator compares both for your numbers.

Can I switch between regimes every year?

Salaried individuals can choose either regime each financial year. Those with business income face restrictions on switching back to the old regime after opting out.

Does my age category affect the tax calculation?

Age only changes the old regime's basic exemption limit and the Section 80D health insurance cap — the new regime slabs are the same for everyone. Senior citizens (60–80) get a higher exemption limit and 80D cap, and super senior citizens (80+) get an even higher exemption limit.
