Frequently Asked Questions

Which tax regime is better for me?

It depends on your deductions. If your total deductions (80C, 80D, HRA, home loan interest, etc.) exceed Rs. 3-4 lakh, the old regime is usually better. If your deductions are minimal, the new regime with its lower tax rates and higher standard deduction is often better.

Can I switch between regimes every year?

Salaried individuals can switch between regimes every financial year. However, those with business income who opt for the new regime can only switch back to old regime once in their lifetime.

Is the new regime default now?

Yes, from FY 2023-24 onwards, the new tax regime is the default option. If you want to use the old regime, you need to specifically opt for it while filing your ITR.

What deductions are not allowed in the new regime?

The new regime does not allow most deductions including Section 80C (PPF, ELSS, etc.), 80D (health insurance), HRA exemption, LTA, home loan interest deduction under Section 24. Only standard deduction of Rs. 75,000 and NPS employer contribution under 80CCD(2) are allowed.

How do I calculate tax under both regimes?

Calculate your gross income, apply allowed deductions to get taxable income, then apply the respective tax slabs. Compare the final tax amount under both regimes to see which saves more.
