Calculate advance tax and instalments
Enter the completed tax estimate first. Then record actual or planned advance-tax payments in the deadline window in which they count.
Advance tax is payable under the regular schedule.
The June target is met. The next cumulative target is 45% by 15 September 2026.
Interest is an indicative planning result. Section 425(4) relief for specified unexpected income is not automatically applied.

Advance tax calculator: what this estimate covers
Advance tax is income-tax paid during the same tax year in which the income is earned. This calculator covers income earned from 1 April 2026 to 31 March 2027. It starts with your completed annual tax estimate, subtracts eligible adjustments and TDS or TCS, applies the ₹10,000 liability test, and builds the correct regular or eligible presumptive payment schedule.
The payment history is date-sensitive. A payment made in July cannot satisfy the target that was due on 15 June. For that reason, the calculator records payments in five statutory windows instead of using one undated amount. It also separates the underlying tax estimate from the duty to pay advance tax. A qualifying senior citizen can remain liable for final income-tax even though advance tax is not required.
How to use the advance tax calculator
- Select the regular schedule unless you qualify for the single-instalment presumptive rule under Section 58(2), Table serial number 1 or 3.
- Select the senior-citizen exception only for a resident individual aged 60 or more during the tax year who has no business or professional income.
- Choose the planning date. The interest summary evaluates deadlines that have already passed by that date.
- Enter estimated total income-tax after rebate, surcharge and 4% cess, but before subtracting the separate eligible adjustments entered below.
- Enter only relief and MAT or AMT credit not already reflected in the tax amount. Do not claim the same reduction twice.
- Enter TDS and TCS expected to be eligible for income included in the tax estimate.
- Record each advance-tax payment in the window in which it was paid or is planned to be paid.
- Review the liability status, next cumulative target, schedule audit, interest-to-date estimate and 90% year-end risk indicator.
Advance tax formula and Section 516 rounding
Section 405 states the statutory advance-tax formula as A = B − C, where B is income-tax on the specified estimated income and C is qualifying TDS or TCS. This calculator includes separate advanced fields for recognised relief and MAT or AMT credit because those items also affect the relevant returned-income or assessed-tax amount. Enter them only when they are not already included in the tax figure.
Section 516 ignores paise and rounds the annual amount payable to the nearest multiple of ₹10. A last rupee digit of five or more rounds up. A lower digit rounds down. This matters at the threshold. A raw result of ₹9,994.99 rounds to ₹9,990, while ₹9,995 rounds to ₹10,000 and reaches the Section 404 test.
The cumulative instalment targets remain the exact statutory percentages of that rounded annual amount. They are not independently rounded to ₹10. If a target contains paise and the payment system accepts whole rupees, pay at least the next whole rupee because Section 408 requires “not less than” the stated percentage.
Worked example
Assume estimated tax after rebate, surcharge and cess is ₹1,20,000. Eligible TDS and TCS are ₹20,000, with no additional relief or credit. Net advance tax is ₹1,00,000. Under the regular schedule, cumulative targets are ₹15,000 by 15 June, ₹45,000 by 15 September, ₹75,000 by 15 December and ₹1,00,000 by 15 March.
If ₹15,000 was paid by 15 June and nothing later is entered, ₹30,000 is needed to reach the September target. The final estimated tax balance is still ₹85,000. The June row is satisfied, while later rows remain planning targets until their deadlines pass.
Advance tax due dates for Tax Year 2026–27
| Due date | Cumulative statutory target | Normal fresh instalment | Section 425 rate on shortfall |
|---|---|---|---|
| 15 June 2026 | 15% | 15% | 3%, subject to the 12% safe harbour |
| 15 September 2026 | 45% | 30% | 3%, subject to the 36% safe harbour |
| 15 December 2026 | 75% | 30% | 3% on the shortfall |
| 15 March 2027 | 100% | 25% | 1% on the shortfall |
The percentages are cumulative. The 45% September target includes the June amount. The 12% and 36% figures are limited interest safe harbours under Section 425. They do not replace the 15% and 45% payment targets in Section 408.
Regular and presumptive advance-tax schedules
| Point | Regular schedule | Eligible presumptive schedule |
|---|---|---|
| Who uses it | Most taxpayers liable for advance tax | Eligible Section 58(2), Table serial number 1 or 3 cases |
| Payment pattern | 15%, 45%, 75% and 100% cumulative | 100% by 15 March |
| Old-law equivalent | General Section 211 schedule | Eligible Sections 44AD and 44ADA cases |
| Important exclusion | Applies when no special schedule is available | Goods-carriage income under Section 58 Table serial number 2 does not receive the one-instalment concession |
Do not choose presumptive merely because some income is estimated. The single 15 March payment rule is limited to the specified eligible business and professional presumptive provisions. A person using that schedule has business or professional income and cannot also use the resident senior-citizen no-business exception.
Resident senior-citizen exception
Section 403(3) removes the advance-tax requirement for an individual resident in India 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 person turning 60 by 31 March 2027 can meet the age condition. A non-resident senior citizen, or a resident senior citizen with business or professional income, does not qualify.
The exception concerns payment timing, not final tax exemption. The calculator therefore keeps the estimated tax after credits visible. It changes the advance-tax status and instalment schedule without deleting the underlying tax balance.
How Section 425 interest is estimated
Section 425 deals with deferment of instalments. For each deadline that falls before the chosen planning date, the calculator compares cumulative payments with the applicable target. June interest is avoided when cumulative payment is at least 12% of returned-income tax, and September interest is avoided at 36%, even if the full statutory target was not reached. December uses the 75% target and March uses 100%.
Rule 269 first ignores any fraction of ₹100 in the shortfall base. A ₹99 shortfall therefore has a zero interest base even though the instalment remains short. The calculated interest is then rounded to the nearest ₹10 under Section 516. The result is an estimate because final Section 425 interest uses tax due on returned income and can be affected by recognised credits and statutory exceptions.
Section 424 final annual default is separate
Section 424 corresponds to old Section 234B. It can apply when no advance tax is paid or advance tax paid by 31 March is less than 90% of assessed tax. The interest rate is 1% for every month or part of a month from 1 April 2027 for the specified period. This page shows a projected 90% warning but does not calculate Section 424 interest because the final assessed tax, return processing date, self-assessment payment date and later assessment events are not known.
Sections 424 and 425 can both apply. Paying the full tax on 31 March can satisfy the final 90% test, but it does not erase the 1% March instalment interest caused by missing the 15 March target.
TDS, TCS, relief and tax credits
Enter TDS or TCS expected for the full tax year only when it relates to income included in the estimate and is expected to satisfy Section 405. Hypothetical withholding cannot always be subtracted when income has already been paid or credited without deduction. Reconcile the result with the official tax statement and payment records before acting.
Relief and MAT or AMT credit inputs are separate so the calculation remains transparent. If combined adjustments exceed the tax estimate, the calculator sets the planning base to zero and reports the unused difference. It does not treat unused relief, credit, TDS, TCS or an excess payment as an automatic refund.
Revised estimates and payments through 31 March
Income can change during the year. Section 406 allows a taxpayer paying on their own accord to revise the estimate and adjust remaining instalments. Recalculate after a large bonus, rent change, interest credit, sale of an asset, new business income or a revised TDS estimate. Keep the calculation used for each payment date.
Section 408(3) treats an amount paid by 31 March as advance tax for the tax year. The separate 16 to 31 March input captures that credit. It reduces the remaining annual balance and can improve the projected Section 424 test, but it does not count as payment by 15 March for Section 425.
Common advance-tax mistakes
- Entering taxable income instead of the calculated income-tax amount.
- Subtracting rebate, relief, tax credit or TDS twice.
- Using one current payment total for every earlier deadline.
- Treating the 45% September figure as an additional 45% instalment.
- Choosing the presumptive schedule for a business outside Section 58 Table serial number 1 or 3.
- Assuming every resident senior citizen is exempt even when business income exists.
- Using old Section 208, 211, 234B or 234C labels for Tax Year 2026–27 payments.
- Selecting AY 2026–27 when the payment belongs to income earned in Tax Year 2026–27.
For advance tax on income earned from April 2026 to March 2027, use the Tax Year 2026–27 selection on the official payment system. AY 2026–27 relates to the preceding income period under the repealed Act.

Frequently asked questions
Who must pay advance tax in Tax Year 2026–27?
A taxpayer generally must pay advance tax when the amount computed under the advance-tax provisions is ₹10,000 or more, unless a statutory exception applies.
What are the advance tax due dates for FY 2026–27?
Regular taxpayers must reach at least 15% by 15 June 2026, 45% by 15 September, 75% by 15 December and 100% by 15 March 2027.
Is the September instalment an additional 45%?
No. The 45% requirement is cumulative. If exactly 15% was paid by June, another 30% is normally needed by September.
Which presumptive taxpayers pay 100% by 15 March?
The single-instalment rule applies to eligible Section 58(2), Table serial number 1 or 3 cases. It does not cover every presumptive activity.
Are all senior citizens exempt from advance tax?
No. The exception is limited to a resident individual aged 60 or more during the tax year who has no business or professional income.
Does the senior-citizen exception remove final income-tax?
No. It removes the advance-payment requirement when its conditions are met. Final income-tax can still remain payable.
What are the 12% and 36% safe harbours?
They prevent Section 425 interest for the June or September shortfall when cumulative payment reaches at least 12% or 36%. They do not replace the statutory 15% and 45% targets.
Is tax paid after 15 March still advance tax?
An amount paid by 31 March is treated as advance tax, but payment after 15 March can still leave Section 425 interest for the March instalment shortfall.
What is the difference between Sections 424 and 425?
Section 425 measures deferment at individual instalment dates. Section 424 addresses the final annual default when advance tax is unpaid or below 90% of assessed tax.
Does this calculator file or pay advance tax?
No. It provides an educational estimate. Make and verify the payment through the official income-tax portal using the correct Tax Year 2026–27 selection.
