Advance tax instalments
Under Section 208 of the Income Tax Act, if your total tax liability exceeds ₹10,000 in a year, you must pay advance tax in four instalments: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. Interest under Sections 234B/234C applies on shortfall.
Common questions about Advance Tax
Who must pay advance tax in India?+
Any taxpayer whose total tax liability (after TDS) exceeds ₹10,000 in a financial year must pay advance tax. This includes salaried employees with significant non-salary income (capital gains, FD interest, rental), self-employed professionals, business owners, and freelancers. Senior citizens aged 60+ without business income are exempt from advance tax and may pay in one go when filing ITR.
What are the advance tax due dates?+
Four installments for FY 2026-27: 15 June 2026 (15% of total tax), 15 September 2026 (45% cumulative), 15 December 2026 (75% cumulative), 15 March 2027 (100%). Presumptive taxation opts (44AD, 44ADA) have a single installment due March 15. Pay via the Income Tax portal using Challan 280.
What is the penalty for missing advance tax?+
Two interests apply: (1) Section 234B — 1% per month on the shortfall if less than 90% of tax is paid by March 31; (2) Section 234C — 1% per month on the shortfall in each quarterly installment. On a ₹1 lakh liability fully skipped until filing, you may owe ₹5,000-₹10,000 in interest. Often it's cheaper to pay a bit extra in advance.
How do I estimate advance tax if income is variable?+
Use last year's ITR as baseline plus expected changes. Project annual salary + interest + expected capital gains + rental. Compute tax under your chosen regime. Adjust each quarter as reality unfolds — e.g., book a large LTCG in Q2 means bumping up the September installment. TDS already deducted counts toward your advance tax — deduct it before calculating the balance.
Is advance tax needed on capital gains?+
Yes, but with relief. You can include capital gains in the installment for the quarter in which the sale happens, not retrospectively. If you sell shares in November 2026, the gain goes into the December and March installments only — no 234C interest for earlier quarters. Same rule applies to casual income (lottery, crossword).
What happens if I overpay advance tax?+
You get a refund with interest (0.5% per month under Section 244A) when you file the ITR. Not ideal — money locked with the government at 6% vs fetching 7%+ in a sweep FD. Better to estimate conservatively; pay exactly 100% via the final March installment. The cost of a small shortfall (1%/month 234B) for a few months is usually worth the liquidity.
