Advance Tax Calculator
Work out your advance tax for Tax Year 2026-27 under the Income-tax Act, 2025: the tax for the year in the new or old regime, what you must have paid by each due date, and the interest for paying late or paying too little. Enter what you have already paid to see how much to pay by 15 December 2026 and 15 March 2027.
Advance tax you have paid
| Due date | Must have paid | You paid | Short by | Interest |
|---|---|---|---|---|
| 15 June 2026 (15%) | ₹20,100 | ₹30,000 | — | — |
| 15 September 2026 (45%) | ₹60,300 | ₹80,000 | — | — |
| 15 December 2026 (75%) | ₹1,00,500 | ₹80,000 | ₹20,500 | ₹615 (3 mo) |
| 15 March 2027 (100%) | ₹1,34,000 | ₹80,000 | ₹54,000 | ₹540 (1 mo) |
Your advance tax for the year is ₹1,34,000. By 15 December 2026 your payments should add up to ₹1,00,500, and by 15 March 2027 to ₹1,34,000.Late instalments so far cost ₹1,155 in interest. Because less than 90% was paid by 31 March, another ₹2,160 is charged until you pay the balance in July.
Interest is 1% a month (part of a month counts as a full month) on shortfalls rounded down to the nearest ₹100. Capital gains count only from the instalment after they arise. Surcharge is applied without marginal relief. Checked 2026-10-23.
Who has to pay advance tax?
Anyone whose tax for the year, after TDS and TCS, is ₹10,000 or more. A resident aged 60 or more with no business or professional income is exempt.
- Freelancers and professionals: clients deduct 10% TDS, often less than the tax due at your slab.
- Business owners, including those on presumptive taxation (one instalment by 15 March).
- Landlords and investors with rent, interest, dividends or capital gains.
- Salaried people only if other income leaves ₹10,000 or more of tax not covered by TDS.
Advance tax due dates for Tax Year 2026-27
Pay a growing share of the year’s tax by four dates.
| Due date | Paid by then, at least | Interest if short |
|---|---|---|
| 15 June 2026 | 15% (none if 12% is paid) | 1% a month for 3 months |
| 15 September 2026 | 45% (none if 36% is paid) | 1% a month for 3 months |
| 15 December 2026 | 75% | 1% a month for 3 months |
| 15 March 2027 | 100% | 1% for 1 month |
Businesses and professionals on presumptive taxation pay 100% by 15 March 2027 in one instalment. Payment made on 31 March still counts as advance tax for the year.
How to calculate advance tax
Estimate your income for the whole year, work out the tax on it in your chosen regime, take off TDS and TCS, and pay the rest in the four instalments. For a consultant with ₹20 lakh of professional income and ₹1 lakh of interest in the new regime:
| Total income | ₹21,00,000 |
| Tax at new regime slabs, plus 4% cess | ₹2,34,000 |
| Less TDS deducted by clients and the bank | ₹1,00,000 |
| Advance tax for the year | ₹1,34,000 |
| Due by 15 June / 15 Sept / 15 Dec / 15 March (cumulative) | ₹20,100 / ₹60,300 / ₹1,00,500 / ₹1,34,000 |
Estimates change during the year: re-run the calculation before each due date with the income you now expect, and pay the difference. Interest is worked out on the tax you finally owe, not on your estimate, so an estimate that was too low early in the year can still cost interest on those instalments.
Interest for late instalments: Section 425 (formerly 234C)
1% a month on the amount you are short at each due date, for 3 months on the June, September and December instalments and 1 month on the March one. The shortfall is rounded down to the nearest ₹100.
The consultant above paid ₹30,000 by June and ₹50,000 more by September, so the first two instalments are covered. Paying nothing more by 15 December leaves ₹20,500 short (₹615 interest); paying nothing by 15 March leaves ₹54,000 short (₹540). If they had paid nothing at all during the year, the interest for late instalments would be ₹6,767.
Interest for paying less than 90%: Section 424 (formerly 234B)
If the advance tax you pay by 31 March is less than 90% of the tax you owe after TDS, 1% a month runs on the unpaid amount from 1 April until you pay it, counting part of a month as a whole month. The consultant’s ₹80,000 is below 90% of ₹1,34,000, so paying the remaining ₹54,000 in July 2027 adds ₹2,160 (4 months). Paying nothing all year and settling in July would add ₹5,360, on top of the ₹6,767.
Capital gains and dividends during the year
Tax on capital gains and dividends counts only from the instalment after the income arises. A gain you cannot predict does not create interest on instalments that fell before it.
A salaried employee with ₹18 lakh salary (TDS ₹1.8 lakh) who books ₹3 lakh of short-term gains on shares in November owes ₹33,200 more. None of it was due in June or September; 75% (₹24,900) is due by 15 December and the rest by 15 March. Gains made after 15 March can be paid by 31 March without interest for late instalments. Use the Tax-Loss Harvesting Calculator to cut the tax on gains first.
Salaried with other income: TDS or advance tax?
If you have rent, interest or freelance income, you can declare it to your employer and have more TDS deducted from your salary instead of paying advance tax. Your employer can take it into account for the rest of the year. Otherwise, pay advance tax on that income by the due dates. Check the Income Tax Calculator for your total tax, and the TDS Calculator for what is already being deducted.
How to pay advance tax
- Go to the income tax e-filing portal and open e-Pay Tax (you can pay without logging in, using your PAN).
- Choose Tax Year 2026-27 (the portal may still show AY 2027-28) and the type Advance Tax (100), not Self-Assessment Tax (300).
- Pay by net banking, UPI, debit or credit card, or at a bank branch.
- Save the challan with its BSR code, date and serial number; you need them in your return.
- Check after a few days that the payment shows in Form 26AS.
Missed an instalment? What to do now
Pay as soon as you can. Interest on a missed instalment is fixed once the date passes, but each later instalment you meet, and reaching 90% by 31 March, avoids more. Any tax still due after 31 March is paid as self-assessment tax, with interest, before you file your return.
