Advance Tax: formula sheet
Key formulas
- Meaning of advance tax
- Advance tax = tax on current-year estimated income, paid in instalments during the same tax year
- This is the pay-as-you-earn principle. The tax year is the year in which the income is earned.
- Net tax tested against the threshold
- Estimated tax payable = Tax on estimated total income (after rebate and relief) − TDS − TCS
- Use only TDS and TCS that will be deducted or collected on income included in your total income.
- Liability test
- Liable if estimated tax payable ≥ ₹10,000
- Exactly ₹10,000 means liable. ₹9,999 means not liable.
- Senior citizen exemption
- Exempt if: resident individual + aged 60 or more at any time in the tax year + no business or profession income
- All three conditions must be met. Failing any one makes the person liable, if the ₹10,000 test is also met.
- Who is covered
- Every person (individual, HUF, firm, company and others) whose estimated tax is ₹10,000 or more
- The liability is not limited to businesses. Salaried persons with other income can be liable too.
- Advance tax payable
- Advance tax payable = Estimated tax on current-year total income (including surcharge and cess) − TDS − TCS
- TDS and TCS are those expected to be deducted or collected on income and transactions of the same tax year.
- Liability threshold
- Advance tax is payable only if the balance after TDS and TCS ≥ ₹10,000
- If the balance is below ₹10,000, no advance tax is due. Exactly ₹10,000 is payable.
- Cess
- Health and education cess = 4% × (income-tax + surcharge)
- Add it before deducting TDS and TCS.
- Instalments for most assessees (cumulative)
- By 15 June: 15% | by 15 September: 45% | by 15 December: 75% | by 15 March: 100%
- Percentages are of the advance tax payable and are cumulative. The amount of each instalment is the difference from the previous cumulative figure.
- Presumptive business assessees
- Whole advance tax in one instalment on or before 15 March
- This is for those who opt for the presumptive scheme for business. Check the instalment topic for the exact persons covered.
- Individual new-regime slabs used in the examples
- Up to ₹4,00,000: nil | ₹4,00,001–8,00,000: 5% | ₹8,00,001–12,00,000: 10% | ₹12,00,001–16,00,000: 15% | ₹16,00,001–20,00,000: 20% | ₹20,00,001–24,00,000: 25% | above ₹24,00,000: 30%
- In the exam, use the rates given in the question or the rates in your tax-year 2026-27 material.
- Instalment schedule (section 408(1))
- 15 June: ≥ 15% | 15 September: ≥ 45% | 15 December: ≥ 75% | 15 March: 100%
- Percentages are cumulative, applied to the advance tax payable.
- Amount of each instalment
- Instalment = Cumulative % × Advance tax − Advance tax already paid
- For the 15 March instalment the cumulative % is 100%.
- Presumptive taxation rule (section 408(2))
- Whole advance tax on or before 15 March
- Applies to an assessee declaring profits under section 58(2), Table Sl. No. 1 or 3.
- Payment by 31 March (section 408(3))
- Paid on or before 31 March = advance tax of that financial year
- Treated as advance tax for all purposes of the Act.
- Advance tax payable
- Tax on estimated total income − TDS/TCS expected to be credited
- Advance tax is payable if this balance is ₹10,000 or more. Check the threshold and the exemption for resident senior citizens without business income in your Section 408 notes.
- Cumulative instalments (non-presumptive assessee)
- By 15 June: 15% | By 15 September: 45% | By 15 December: 75% | By 15 March: 100%
- These percentages are cumulative, not separate. Each is a percentage of the advance tax payable for the year.
- Revised estimate
- Revised cumulative % × revised advance tax − amount already paid = payment due now
- Apply the percentage of the next due date to the new figure. Do not wait for the year end.
- Capital gains / casual income arising after an instalment date
- Tax on that income is included in the cumulative amount due at the next instalment date on or after it arises, and stays in the cumulative total after that
- It is paid once, as part of the cumulative amount. If it arises after 15 March, pay the whole tax on it by 31 March.
- Default interest (shortfall of advance tax)
- Interest = 1% × number of months (part of a month = full month) × (Assessed tax − Advance tax paid)
- Applies only if advance tax paid is less than 90% of assessed tax. Round the shortfall down to the nearest ₹100. Simple interest.
- Assessed tax
- Assessed tax = Tax on total income − TDS/TCS and other credits allowed
- This is the base for the 90% test. Advance tax paid is not deducted when finding assessed tax.
- Period for default interest
- From 1 April after the tax year to the date the total income is determined (or, in a sum, to the month of paying the balance tax)
- Self-assessment tax paid reduces the shortfall from the month of payment. Count April as the first month.
- Instalments: companies
- 15% by 15 June; 45% by 15 Sept; 75% by 15 Dec; 100% by 15 March
- Cumulative percentages of advance tax due.
- Instalments: other assessees
- 30% by 15 Sept; 60% by 15 Dec; 100% by 15 March
- No June instalment. Presumptive-taxation assessees pay the whole amount by 15 March.
- Deferment interest
- Interest = 1% × months × shortfall in the instalment
- Months: 3 for the shortfall of each instalment due in June, September and December, as applicable to the assessee type (a company has all three; other assessees have only September and December); 1 month for the March shortfall.
- No deferment interest on early shortfall
- Company: ≥ 12% paid by 15 June and ≥ 36% by 15 Sept. Other assessees: ≥ 27% paid by 15 Sept
- Percentages are of tax due on the returned income. There is no such relief for the December instalment. The March instalment must reach 100%.
Quick revision
- Advance tax is payable when estimated tax, after TDS and TCS, is ₹10,000 or more in the tax year.
- A resident senior citizen with no business income is not required to pay advance tax.
- Advance tax is paid on current-year estimated income, not on last year's income.
- Net tax for advance tax = total tax with surcharge and cess minus TDS and TCS.
- Normal instalments are cumulative: 15% by 15 June, 45% by 15 September, 75% by 15 December and 100% by 15 March.
- A presumptive taxpayer pays the whole amount in one instalment by 15 March.
- Advance tax paid by 31 March is treated as advance tax paid for that tax year.
- Interest for deferment on a June, September or December instalment shortfall is charged at 1% per month for 3 months.
- Interest on a March shortfall is charged at 1% per month for 1 month.
- Interest is simple interest, and a part of a month counts as a full month.
- Interest for deferment is not charged if the shortfall arises from income, such as capital gains, that could not be foreseen and tax is paid in the remaining instalments.
- Always check whether the question asks for the instalment, the shortfall or the interest.
Common mistakes
- Testing the ₹10,000 limit against total tax without subtracting TDS and TCS. Fix: Always write the line: Tax − TDS − TCS = net tax. Compare only the net figure with ₹10,000.
- Treating a person with net tax of exactly ₹10,000 as not liable. Fix: The rule is ₹10,000 or more. Exactly ₹10,000 makes the person liable.
- Deducting TDS and TCS before adding cess, or forgetting cess altogether. Fix: Always follow the order: tax, rebate, surcharge, cess, then subtract TDS and TCS.
- Paying advance tax when the balance is below ₹10,000. Fix: Test the ₹10,000 limit on the balance after subtracting TDS and TCS.
- Treating the percentages as separate amounts of 15%, 45%, 75% and 100% each. Fix: Remember they are cumulative. Total paid by each date must reach that percentage. The fresh payment is the difference.
- Saying companies and non-companies have different due dates under section 408. Fix: Section 408(1) applies one table to all assessees liable to pay advance tax, other than those in sub-section (2). The split is presumptive versus others, not company versus non-company.
- Treating 15%, 45%, 75% and 100% as separate amounts of each instalment Fix: Remember they are cumulative. The September payment is 30% of the year's tax (45% − 15%), if June was paid in full.
- Spreading the tax on capital gains over all four instalments Fix: Include it only from the first instalment date on or after the date the gain arose. A gain arising in November is included in the cumulative amount due by 15 December. It stays in the 15 March total and is paid once.
- Charging default interest on the whole assessed tax instead of the shortfall. Fix: Once the 90% test fails, interest is on assessed tax minus advance tax paid, not on the full tax.
- Using advance tax paid to reduce assessed tax before the 90% test. Fix: Only TDS, TCS and similar credits reduce assessed tax. Advance tax is the amount you compare with it.
Exam tips
- In MCQs, the trap is nearly always one of three things: TDS not subtracted, exactly ₹10,000, or a senior citizen with business income. Check all three before answering.
- In a written answer, state the rule in one line first (net tax of ₹10,000 or more), then show the subtraction. Examiners give step marks for the formula and for the conclusion.
- Look for hints in the question: 'resident', 'aged 62', 'pension and interest only'. These signal the exemption. 'Non-resident' or 'professional fees' signals the opposite.
- If a question asks for the advance tax payable, first prove liability with the ₹10,000 test, then compute instalments. Skipping the test can lose marks.
- Use the terms 'tax year' and the Income-tax Act, 2025 throughout. Do not write 'assessment year'.
- Always draw the final statement: tax, cess, TDS, TCS, balance, and the ₹10,000 test. Markers look for each line.
- Write the instalments as cumulative percentages and show the difference. Show the total check at the end.
- If the question says the assessee is a senior citizen, check for business income before saying no advance tax is due.
