Frequently Asked Questions
Quick answers to common questions
Who needs to pay advance tax in India?+
Any taxpayer with estimated annual tax liability of ₹10,000 or more after TDS must pay advance tax. This includes salaried individuals with additional income from rent, freelance, capital gains, or interest. Senior citizens (75+) are exempt if their only income is pension and interest from specified banks.
What are the advance tax payment due dates for FY 2025-26?+
Advance tax for FY 2025-26 must be paid in four instalments: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. Missing or underpaying these leads to interest under Section 234C at 1% per month on the shortfall.
What is the interest penalty for not paying advance tax?+
If advance tax paid by March 31 is less than 90% of tax liability, Section 234B interest applies at 1% per month on the deficit from April 1. Section 234C applies if instalments fall short of the scheduled percentages — 1% per month on the shortfall for each quarter.
