Which Tax Regime is Best for Tax Saving?
The choice between New and Old Tax Regime depends primarily on your total deductions. If your deductions under the old regime (80C, 80D, HRA, etc.) exceed approximately ₹3.75 lakh for income above ₹15L, the old regime is generally better. For those with fewer investments or just starting their careers, the new regime's lower slab rates often result in lower taxes.

Frequently Asked Questions
Which tax regime is better for salaried employees?
For salaried employees with significant investments (80C maxed, HRA, 80D), the old regime is often better. If you have minimal deductions or are just starting out, the new regime's lower slab rates may result in lower taxes. Use this calculator to compare both.
Can I switch between tax regimes every year?
Salaried individuals can switch between regimes every financial year when filing their ITR. However, if you have business income, you can switch to the old regime only once. It's advisable to calculate both options each year as your income and investments change.
What deductions are allowed in the new tax regime?
The new tax regime allows only the standard deduction of ₹75,000 for salaried employees. Deductions like 80C, 80D, HRA, LTA, and home loan interest are not available. However, employer's contribution to NPS under 80CCD(2) is still allowed.
Is there a tax rebate under the new regime?
Yes! Under Section 87A, if your taxable income is up to ₹12 lakh under the new regime, you get a full tax rebate — meaning zero tax payable. Under the old regime, this rebate applies if taxable income is up to ₹5 lakh.
