What is advance tax?
Advance tax means paying your estimated income tax in installments during the financial year, instead of one lump sum at the end. It spreads the tax burden and keeps government revenue flowing through the year.
If your estimated tax liability (after TDS/TCS) is ₹10,000 or more, you generally need to pay advance tax.
What are the due dates for advance tax?
For most taxpayers, advance tax is paid in four installments:
| Due date | Advance tax payment |
|---|
| On or before 15 June | 15% of advance tax |
| On or before 15 September | 45% of advance tax (− amount already paid) |
| On or before 15 December | 75% of advance tax (− amount already paid) |
| On or before 15 March | 100% of advance tax (− amount already paid) |
Presumptive taxation (44AD / 44ADA)
If you have opted for the presumptive taxation scheme under sections 44AD or 44ADA, you generally pay 100% of advance tax on or before 15 March.

Advance tax vs self-assessment tax
Advance tax is paid during the year based on estimates. Self-assessment tax is paid after year-end when you finalise your return, if any balance still remains after TDS, TCS, and advance tax.
Interest under sections 234B and 234C may apply if you underpay or delay advance tax installments.
