Frequently Asked Questions
Any person whose estimated tax liability for the year is Rs. 10,000 or more after reducing TDS must pay advance tax. This includes salaried individuals with other income, self-employed professionals, freelancers, and businesses. Senior citizens (60+) without business income are exempt from advance tax.
For FY 2025-26, advance tax is payable in four instalments:
- 15% by June 15, 2025
- 45% (cumulative) by September 15, 2025
- 75% (cumulative) by December 15, 2025
- 100% by March 15, 2026
Interest is charged under two sections:
- Section 234B: 1% per month if you pay less than 90% of assessed tax as advance tax
- Section 234C: 1% per month for deferment of individual instalments
Both are simple interest calculated from the due date to the date of payment.
The new tax regime offers lower tax rates but limited deductions (only standard deduction). The old regime has higher rates but allows all deductions under 80C, 80D, HRA, etc.
As a thumb rule, if your total deductions exceed ₹3.75 lakh, the old regime may be better. Use our calculator to compare both regimes for your specific situation.
