How to pay advance tax

Advance tax is paid online through the income tax e-filing portal.

  • Use challan ITNS 280 (minor head 100 for advance tax) on the e-pay tax service.
  • Keep the challan receipt; it is shown in Form 26AS and your AIS.
  • Re-estimate your income before each due date, especially after large gains.
  • Capital gains or windfalls after a due date only need tax in the remaining instalments.
