Reviewed on July 13, 2026 using the Income-tax Act, 2025 as amended by Finance Act, 2026 and official transition guidance for Tax Year 2026–27.

Advance tax is income-tax paid during the same tax year in which income is earned. For Tax Year 2026–27, Section 404 requires advance tax when the amount computed after eligible tax deducted or collected at source is ₹10,000 or more, unless a statutory exception applies.

Quick answer: Net advance tax generally equals estimated income-tax after rebate, surcharge and cess, less eligible relief or tax credits and TDS/TCS relating to the estimated income. Regular taxpayers pay cumulative minimums of 15%, 45%, 75% and 100%; eligible presumptive taxpayers pay 100% by 15 March.

How to use the advance tax calculator

  1. Select the regular instalment schedule or the eligible presumptive Section 58(2) schedule.
  2. Select the resident senior-citizen exception only when both age, residence and no-business-income conditions are satisfied.
  3. Enter estimated total income-tax after rebate, surcharge and cess.
  4. Enter eligible relief and tax credits separately from expected TDS/TCS.
  5. Add advance tax already paid for the same tax year.
  6. Review the remaining balance and cumulative target for each due date.
Net liability testAdvance tax becomes mandatory when the computed amount payable is ₹10,000 or more.
Cumulative targetsSeptember's 45%, for example, includes the amount already required by June; it is not an extra 45%.

Advance tax calculation formula

Net advance tax = Estimated income-tax − eligible relief and credits − expected TDS/TCS
Additional amount for a due date = Cumulative statutory target − advance tax already paid

The first result is rounded to the nearest ₹10 for planning. Do not subtract advance tax already paid when testing the original ₹10,000 liability threshold; payments already made reduce the remaining balance and future cumulative shortfall.

Advance tax due dates for Tax Year 2026–27

Due dateCumulative minimumFresh instalment if earlier targets were paid exactly
15 June 202615% of advance tax15%
15 September 202645% of advance tax30%
15 December 202675% of advance tax30%
15 March 2027100% of advance tax25%

Section 408 states that payments made on or before 31 March are also treated as advance tax for that tax year. This does not automatically remove interest arising from a missed or short earlier instalment.

Presumptive taxation schedule

An eligible assessee declaring presumptive profits under Section 58(2), Table serial number 1 or 3, may discharge the whole advance-tax liability in one instalment on or before 15 March 2027. These provisions correspond to the familiar business and professional presumptive schemes under Sections 44AD and 44ADA of the repealed Act.

Resident senior-citizen exception

Section 403 excludes a resident individual who is aged 60 years or more at any time during the tax year and has no income chargeable under Profits and gains of business or profession. A non-resident senior citizen, or a resident senior citizen with business or professional income, does not qualify for this exception merely because of age.

Advance tax example

Suppose estimated total income-tax after rebate, surcharge and cess is ₹1,20,000, expected TDS/TCS is ₹20,000 and there is no other eligible relief or tax credit. Net advance tax is ₹1,00,000.

  • By 15 June: cumulative target ₹15,000
  • By 15 September: cumulative target ₹45,000; normally another ₹30,000
  • By 15 December: cumulative target ₹75,000; normally another ₹30,000
  • By 15 March: cumulative target ₹1,00,000; normally the final ₹25,000
Capital gains and unexpected income: Section 425 contains relief from instalment-interest in specified cases such as capital gains, certain dividend income or business income arising for the first time, when the related tax is paid in the remaining instalments or by 31 March as permitted. Eligibility depends on the facts and exact provision.

Interest for short or late advance tax

Under the Income-tax Act, 2025, Section 424 corresponds to the earlier Section 234B and can apply when advance tax is not paid or is below 90% of assessed tax. Section 425 corresponds to the earlier Section 234C and addresses deferment or shortfall of instalments. This calculator does not estimate interest because the result depends on actual payment dates, returned income, recognised credits and statutory exceptions.

What is the advance tax threshold for Tax Year 2026–27?
Section 404 of the Income-tax Act, 2025 sets the threshold at ₹10,000 or more. Official transition guidance confirms that this limit is unchanged from the repealed Act.
What are the advance tax due dates?
Regular taxpayers pay at least 15% by 15 June, 45% cumulatively by 15 September, 75% cumulatively by 15 December and 100% by 15 March.
Do presumptive taxpayers pay quarterly advance tax?
An eligible assessee under Section 58(2), Table serial number 1 or 3, pays the whole advance-tax amount in one instalment on or before 15 March.
Are senior citizens exempt from advance tax?
A resident individual aged 60 or more is exempt only when there is no income chargeable under Profits and gains of business or profession. Both conditions must be satisfied.
Do salaried employees need to pay advance tax?
Employer TDS often covers salary tax. However, if tax remaining after eligible TDS/TCS is ₹10,000 or more because of rent, interest, capital gains, side income or insufficient TDS, advance tax may still be payable.
Is 45% due in September an additional 45%?
No. It is a cumulative target. If exactly 15% was paid by June, another 30% is normally needed by September to reach 45%.
Is tax paid by 31 March treated as advance tax?
Yes. Section 408 treats an amount paid as advance tax on or before 31 March as advance tax for that financial year. Interest for earlier shortfalls may still apply.
What happens if advance tax is paid late?
Interest may apply under Section 424 for default or insufficient overall advance tax and under Section 425 for deferred or short instalments, subject to the conditions and exceptions in those sections.
Does advance tax reduce business profit?
No. Advance tax is a payment toward income-tax liability, not a deductible business expense. It is adjusted against the final tax payable for the tax year.
