Advance tax means paying your income tax during the year it is earned, in instalments, instead of all at once when you file. It mostly affects freelancers, business owners and people with rent, interest or capital gains. Salaried people usually don’t need it, because TDS covers their salary, unless they have a lot of other income.
The formula
tax for the year = income tax on your income (slabs, rebate, surcharge, 4% cess)
advance tax = tax for the year − TDS and TCS
pay advance tax if that is ₹10,000 or more (not if you’re 60+ with no business income)
pay by: 15 June 15%, 15 Sept 45%, 15 Dec 75%, 15 March 100% (running totals)
presumptive 44AD / 44ADA: 100% by 15 March
234C = shortfall at each date × 1% × 3 months (1 month for March)
234B = unpaid tax × 1% × months from 1 April, if under 90% was paid by 31 March
Worked example
A freelancer with ₹20,00,000 of income in FY 2026-27, the new regime and ₹50,000 of TDS taken by clients.
Tax: 5% of ₹4 lakh (₹20,000) + 10% of ₹4 lakh (₹40,000) + 15% of ₹4 lakh (₹60,000) + 20% of ₹4 lakh (₹80,000) = ₹2,00,000, plus 4% cess of ₹8,000 = ₹2,08,000.
Advance tax = ₹2,08,000 − ₹50,000 = ₹1,58,000, which is over ₹10,000, so it is due:
- By 15 June 2026: 15% = ₹23,700
- By 15 September 2026: 45% = ₹71,100 in total, so ₹47,400 more
- By 15 December 2026: 75% = ₹1,18,500 in total, so ₹47,400 more
- By 15 March 2027: 100% = ₹1,58,000 in total, so ₹39,500 more
If nothing is paid until 31 July 2027: 234C is ₹23,700 × 3% (₹711) + ₹71,100 × 3% (₹2,133) + ₹1,18,500 × 3% (₹3,555) + ₹1,58,000 × 1% (₹1,580) = ₹7,979. 234B is ₹1,58,000 × 1% × 4 months (April to July) = ₹6,320. Interest in all: ₹14,299.
If ₹20,000 is paid on 10 June, ₹50,000 on 14 September, ₹40,000 on 20 December and ₹30,000 on 15 March: June (₹20,000, over 12%) and September (₹70,000, over 36%) carry no interest. By 15 December only ₹70,000 was paid against ₹1,18,500, so 234C is ₹48,500 × 3% = ₹1,455. By 15 March ₹1,40,000 was paid against ₹1,58,000: ₹18,000 × 1% = ₹180. 234B applies because ₹1,40,000 is less than 90% (₹1,42,200): ₹18,000 × 1% × 4 = ₹720. Interest in all: ₹2,355.
Due dates for FY 2026-27
| Pay by | At least (running total) | Presumptive 44AD / 44ADA |
|---|---|---|
| 15 June 2026 | 15% | — |
| 15 September 2026 | 45% | — |

If a due date falls on a bank holiday, paying on the next working day counts. Tax paid by 31 March still counts as advance tax for 234B, though it is late for the 15 March instalment.
Interest: 234C and 234B
- 234C (late instalments): 1% a month on the shortfall at each date, for a fixed 3 months for June, September and December and 1 month for March, however soon you catch up. No interest at June if you paid at least 12%, or at September if you paid at least 36%. Presumptive taxpayers are only checked at 15 March.
- 234B (not enough by 31 March): if your advance tax paid by 31 March is less than 90% of the tax due after TDS, 1% a month on the unpaid tax from 1 April until you pay it. A part of a month counts as a whole month.
- The amount interest is charged on is rounded down to a multiple of ₹100.
These are the interest rules of sections 234B and 234C of the Income-tax Act 1961. The Income-tax Act 2025 renumbered them from 1 April 2026; the interest rules above (1% a month or part month, the 90% test for 234B, the 12% / 36% / 75% / 100% shortfall tests and 3, 3, 3 and 1 months for 234C, only the March test for presumptive income, and rounding down to ₹100 under Rule 119A) were checked on 18 October 2026 on the Income Tax Department's interest payable page. The rate is editable in Advanced in case it changes.
Tips
- Your income changes during the year? Re-estimate before each date and pay the new running total. Only the shortfall against the final tax counts for interest.
- Pay online with challan 280 (ITNS 280) on the e-filing portal, choosing “advance tax”. Keep the challan number for your return.
- Check your TDS in your AIS or Form 26AS before you work out what is left.

Common questions
Who has to pay advance tax in India?
Anyone whose tax for the year, after TDS and TCS, is ₹10,000 or more. That usually means freelancers, business owners, people with rent, interest or capital gains, and salaried people with big income outside their salary. A resident senior citizen (60 or over) with no business or professional income doesn’t have to pay it.
What are the advance tax due dates for FY 2026-27?
At least 15% of the year’s tax by 15 June 2026, 45% by 15 September 2026, 75% by 15 December 2026 and 100% by 15 March 2027. These are running totals, so on ₹1,58,000 of tax you pay ₹23,700, then ₹47,400, ₹47,400 and ₹39,500. If a date is a bank holiday, the next working day counts.
When do people under presumptive tax (44AD / 44ADA) pay advance tax?
They can pay the whole year’s advance tax in one go by 15 March. There’s nothing to pay in June, September or December, though paying earlier is allowed.
What is the interest for paying advance tax late?
Two kinds. Section 234C charges 1% a month on the shortfall at each due date, for 3 months (1 month for March), with no charge at June if you paid 12% or at September if you paid 36%. Section 234B charges 1% a month on the unpaid tax from 1 April until you pay, if you paid less than 90% by 31 March. The sections were renumbered by the Income-tax Act 2025.
Do salaried people pay advance tax?
Usually not, because the employer takes TDS from the salary every month. But if you have other income such as rent, FD interest, capital gains or freelance work, and the tax left after TDS is ₹10,000 or more, you need to pay advance tax on it.
