Frequently Asked Questions
What is advance tax and who needs to pay it?
Advance tax is income tax paid in installments during the financial year instead of lump sum at year-end. If your total tax liability after TDS exceeds ₹10,000, you must pay advance tax. Applicable to: self-employed, business owners, freelancers, capital gains earners, and high-income individuals with inadequate TDS.
What are the advance tax due dates for FY 2025-26?
Four installments: 15% by June 15, 2026 (15% of estimated annual tax), 45% by September 15, 2026 (cumulative 45%), 75% by December 15, 2026 (cumulative 75%), 100% by March 15, 2027 (remaining amount). Miss any date, you pay interest under Section 234B (1% per month) or 234C.
How do I calculate my advance tax liability?
Estimate your total annual income from all sources (salary, business, capital gains, interest, rent). Calculate tax as per applicable regime and slab rates. Subtract TDS already deducted. If remaining tax > ₹10,000, you must pay advance tax in prescribed installments. Use this calculator for accurate estimation.
What happens if I don't pay advance tax or pay late?
Interest charges apply: Section 234B - 1% per month simple interest on shortfall if full tax not paid by March 15. Section 234C - Interest for deferment of installments (1% per month for each delayed/short installment). These interests can accumulate to 8-12% of tax due, significantly increasing your liability.
Can salaried employees skip advance tax payment?
If your employer deducts adequate TDS covering your full tax liability, advance tax is not required. However, if you have additional income (rental, capital gains, interest, freelance) and total tax after TDS exceeds ₹10,000, you must pay advance tax. Review your income sources carefully before March.

If you were to pay ₹30,000 by Sept 15 but paid only ₹20,000, shortfall is ₹10,000. Interest = ₹10,000 × 1% × 3 months (till Dec) = ₹300.
