Enter what you paid between one due date and the next, counting a late payment towards the next instalment. Interest assumes you pay only what's entered, so fill in the instalments you plan to pay to see it drop. Interest for a missed date is fixed once the date passes, even if you catch up later.
Who has to pay advance tax
Anyone whose tax for the year, after TDS and TCS, comes to ₹10,000 or more has to pay it in advance during the year instead of in one go at filing time. That mostly means freelancers, consultants, business owners and landlords, but also salaried people with sizeable interest, rent or capital gains that their employer's TDS doesn't cover. Resident senior citizens (60 or older) with no business or professional income are exempt.
For tax year 2026-27, the instalments are cumulative: 15% of the year's tax by 15 June 2026, 45% by 15 September, 75% by 15 December and 100% by 15 March 2027. If you declare business or professional income under the presumptive scheme, section 58 of the Income-tax Act, 2025 (the old sections 44AD and 44ADA), you can pay the whole amount in one instalment by 15 March instead. The 44ADA & 44AD Calculator works out that amount from your receipts.
This calculator uses the new tax regime. To see how the tax itself is worked out, use the Income Tax Calculator. To check the TDS your clients should be deducting from your fees, use the TDS Calculator.
Interest if you miss an instalment
Section 425 of the Income-tax Act, 2025 (section 234C of the old Act) charges simple interest at 1% a month on the shortfall at each due date. For the June, September and December instalments, that's 3 months of interest (3% of the shortfall), and for the March instalment it's 1 month (1%). The shortfall is rounded down to the nearest ₹100 first. There's no interest for June if you've paid at least 12% of the tax by then, or for September if you've paid at least 36%.
This interest is fixed once the date passes: catching up later doesn't reduce it, but paying the full amount due by the next date stops it growing. If you pay less than 90% of the year's tax by 31 March, section 424 (the old 234B) adds a further 1% a month from April until you pay the balance.
Worked example
A freelancer expects ₹20,00,000 of profit this year, with no salary and no TDS. Tax under the new regime is ₹2,00,000 plus 4% cess, which comes to ₹2,08,000. The cumulative amounts due are ₹31,200 by 15 June, ₹93,600 by 15 September, ₹1,56,000 by 15 December and ₹2,08,000 by 15 March.
If they paid nothing in June or September, the interest for those two instalments is already fixed at ₹936 (3% of ₹31,200) plus ₹2,808 (3% of ₹93,600), a total of ₹3,744. Paying ₹1,56,000 by 15 December avoids any interest for December. If the same freelancer instead declared 50% of ₹40,00,000 in receipts under the presumptive scheme, the whole ₹2,08,000 would be due by 15 March 2027, with no interest for the earlier dates.
Frequently asked questions
When is the next advance tax instalment due?
The next one is 15 December 2026, by which 75% of the year's tax must be paid, counting everything paid in June and September. The last instalment is 15 March 2027 for 100%. Presumptive taxpayers under section 58 (old 44AD/44ADA) pay the whole amount by 15 March.
I missed the 15 September instalment. What should I do?
Pay what you owe as soon as you can, and at the latest by 15 December along with the December instalment. Interest for September is 3% of the shortfall and is already fixed, so paying earlier doesn't reduce it. Paying at least 75% of the year's tax by 15 December avoids further interest for that date.
Do salaried employees have to pay advance tax?
Usually not, because the employer deducts TDS from salary. You only need to pay advance tax if you have other income, such as interest, rent, capital gains or freelance work, that pushes your tax after TDS to ₹10,000 or more for the year.
How do I pay advance tax?
Through the e-Pay Tax service on the income tax e-filing portal, choosing advance tax as the payment type for the right tax year. Keep the challan details, because you'll claim the payment when you file your return.
What if my income turns out different from my estimate?
Advance tax is based on your best estimate at each date, so revise it as the year goes on and pay more in later instalments if your income rises. Interest is worked out on your actual tax for the year, so underestimating early on can still lead to interest for the earlier dates. If you've paid too much, you get the excess back as a refund after filing.
