How advance tax is worked out
How is advance tax calculated?
Work out the tax for the year, take off TDS, and pay the balance in instalments by the due dates.
Taxable income = gross income − standard deduction − deductions
Tax = slab tax − rebate + surcharge + 4% cess
Net tax = tax − TDS
Instalment = net tax × cumulative % − earlier instalments
When is advance tax due for tax year 2026-27?
Pay a total of 15% by 15 June 2026, 45% by 15 September 2026, 75% by 15 December 2026 and 100% by 15 March 2027.
| Pay by | Cumulative share |

| 15 September 2026 | 45% |

Worked example
A resident below 60 expects a salary of ₹ 12,00,000 and ₹ 6,00,000 of other income, in the new regime. TDS for the year is ₹ 1,00,000.
| Particulars | Amount |
|---|---|
| Salary | ₹ 12,00,000 |
| Other income | ₹ 6,00,000 |
| Less: Standard deduction (salary only) | ₹ -75,000 |
| Taxable income | ₹ 17,25,000 |
| 5% on ₹ 4,00,000 to ₹ 8,00,000 | ₹ 20,000 |
| 10% on ₹ 8,00,000 to ₹ 12,00,000 | ₹ 40,000 |
| 15% on ₹ 12,00,000 to ₹ 16,00,000 | ₹ 60,000 |
| 20% on ₹ 16,00,000 to ₹ 17,25,000 | ₹ 25,000 |
| Tax on income (no rebate above ₹12 lakh) | ₹ 1,45,000 |
| Health & Education Cess (4%) | ₹ 5,800 |
| Total tax | ₹ 1,50,800 |
| Less: TDS | ₹ -1,00,000 |
| Net tax payable | ₹ 50,800 |
Net tax of ₹ 50,800 is ₹10,000 or more, so advance tax is due in four instalments: ₹ 7,620 by 15 June 2026, ₹ 15,240 by 15 September 2026, ₹ 15,240 by 15 December 2026, ₹ 12,700 by 15 March 2027. In the old regime with no deductions, total tax on the same income is ₹ 3,51,000.
Edge cases
- Rebate near ₹12 lakh. In the new regime, taxable income up to ₹12,00,000 pays no tax, because the rebate covers up to ₹60,000. Above that, tax cannot be more than the income above ₹12 lakh. At ₹ 12,10,000, slab tax is ₹ 61,500, relief of ₹ 51,500 brings it to ₹10,000, and with cess the total is ₹ 10,400. The relief ends at about ₹12.7 lakh of taxable income.
- Standard deduction is for salary only. A salary of ₹ 12,75,000 leaves ₹12,00,000 taxable and ₹ 0 tax. The same amount of business or other income gets no standard deduction, so tax is ₹ 74,100.
- Old regime rebate. Up to ₹12,500 when taxable income is ₹5,00,000 or less. There is no marginal relief above ₹5 lakh.
- Seniors. A resident aged 60 or more with no business or professional income does not pay advance tax (section 403(3)). Tax due is paid as self-assessment tax before filing. With business or professional income, the instalments apply.
- The ₹10,000 threshold. Advance tax applies when net tax after TDS is ₹10,000 or more (section 404). At ₹9,999 no instalments are due.
- High incomes. Surcharge starts above ₹50 lakh, with marginal relief at each threshold. The new regime caps it at 25%.
