Frequently Asked Questions
Who needs to pay advance tax?
Any individual whose total tax liability for the year exceeds ₹10,000 (after TDS) must pay advance tax. This includes salaried employees with other income (capital gains, rent, FD interest), freelancers, business owners, and self-employed professionals. Salaried employees with only salary income where employer deducts TDS are generally exempt.
What are the advance tax due dates for Tax Year 2026-27?

What is the penalty for not paying advance tax?
Interest under Section 234B applies at 1% per month if advance tax paid is less than 90% of total tax. Section 234C charges 1% per month for shortfall in each installment (3 months per installment). Both are calculated on the deficit amount.
Is advance tax applicable for capital gains?
