Frequently Asked Questions

Who needs to pay advance tax?

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.

What are the advance tax due dates for FY 2025-26?

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; and 100% by March 15, 2026. If the due date falls on a Sunday or public holiday, the next working day is the due date.

What is the penalty for not paying advance tax?

Interest under Section 234B is charged at 1% per month on unpaid advance tax if you pay less than 90% of assessed tax as advance tax. Interest under Section 234C is charged at 1% per month for deferment of individual instalments. Both are simple interest calculated from the due date to the date of payment.

Which tax regime is better for advance tax - old or new?

The new tax regime (FY 2025-26) offers lower tax rates but no deductions except standard deduction. The old regime has higher rates but allows deductions under 80C, 80D, HRA, etc. If your deductions exceed Rs. 3.75 lakh, the old regime may be better. Use our calculator to compare both regimes for your specific situation.
