Advance Tax Calculator FY 2026-27 (AY 2027-28) 2026

Under Section 208, any taxpayer whose estimated tax liability after TDS and TCS credits is ₹10,000 or more in a financial year must pay advance tax in instalments. Resident senior citizens aged 60 or above with no business or professional income are exempt.

Four instalments: 15% by 15 June, 45% cumulative by 15 September, 75% by 15 December and 100% by 15 March. Taxpayers under the presumptive schemes of Section 44AD or 44ADA pay the full amount in a single instalment by 15 March.

Section 234C charges 1% a month for a shortfall in any quarterly instalment, for three months per default. Section 234B charges 1% simple interest a month from 1 April of the assessment year if less than 90% of the assessed tax was paid by 31 March.

Not if employer TDS covers the full liability. But income your employer does not know about — capital gains, interest, dividends, freelance or rental income — is not covered by salary TDS. If the residual tax exceeds ₹10,000, you must pay advance tax yourself to avoid 234B and 234C interest.

Usually not. The proviso to Section 234C protects income that could not have been estimated earlier: capital gains, winnings from lotteries, dividend income other than deemed dividend, and first-time business income. If the gain arose after an instalment date and you pay the whole tax on it in the remaining instalments, or by 31 March where it arose in the last quarter, no 234C interest is charged. Section 234B still applies if the year's total shortfall exceeds 10% of assessed tax.

Use e-Pay Tax on the income tax portal, which has replaced the old bank Challan 280 page. Log in, choose the assessment year — for income earned in FY 2026-27 that is AY 2027-28 — and pick minor head 100, Advance Tax. Do not select 300, which is self-assessment tax paid after the year ends. Pay by net banking, UPI, card or at a bank counter, and save the challan; its BSR code, date and serial number go into your return and show up in Form 26AS.

Yes. Section 209 says you estimate the tax on your total income for the year and then reduce the TDS and TCS that is deductible or collectible on that income. Only the balance is payable as advance tax, and the ₹10,000 threshold in Section 208 is tested on that balance. So check Form 26AS and AIS before each instalment date. Be careful with TDS the deductor has not yet deposited — the credit follows what is reported, not what was withheld from you.
