How it works
Advance tax is income tax paid during the year instead of at the end. It applies when the tax left after TDS is ₹10,000 or more, and is paid in four instalments — 15% by 15 June, 45% by 15 September, 75% by 15 December and the full amount by 15 March.
The formula
Advance tax = Tax on income + cess − TDS already deducted- Taxable income
- Income after the standard deduction and any eligible deductions
- Cess
- Health and education cess at 4% of tax
- TDS
- Tax already deducted at source
Worked example
A ₹15 lakh income under the new regime leaves a tax liability paid as four instalments through the year.
Pro tips

Common mistakes
- Skipping the June and September instalments, which attracts interest under section 234C.
- Forgetting to subtract the TDS your employer or clients already deducted.
