What the challan is

On Challan ITNS 280 the minor head for self-assessment tax is 300. The major head for income tax on that challan is 0021. It is used when the draft of the return shows tax still to pay, after tax already deducted and after advance tax already paid. Those credits are matched to Form 26AS and AIS before the balance is worked out. If the draft shows nothing left to pay, this challan is not made.

It is not an instalment

Advance tax is paid during the year, under minor head 100. The calendar rows for those instalments are on the advance-tax page. Income earned in the financial year that ended 31 March 2026 is assessment year 2026-27 on the return being prepared now. Advance tax paid during FY 2026-27 is assessment year 2027-28. A GST payment on Form PMT-06 is a different challan, on the GST portal.

There is no separate date on the 2026 calendar for self-assessment tax. It is paid when the draft shows a balance, before that return is submitted. If the due date in force for the return has passed, the next filing is the belated page. Interest under sections 234A, 234B, and 234C is added only where those sections apply. The amount follows the provision in force and is confirmed before you pay. It is not copied onto this page.

Before it is paid

The desk works the balance from the draft, after TDS and advance tax already paid.
You approve that figure. The breakdown can include basic tax, surcharge, health and education cess at 4%, and interest where a section applies.
You pay it on the income-tax portal. Download the challan receipt and keep the BSR code and the CIN.
Those details go into the return if the portal does not show them. After the return is filed, e-verify within 30 days. That step is on the e-verification page.

Income-tax work starts at ₹2,000 on the Coimbatore income-tax page. The government tax on the challan is separate. The quote is confirmed before filing. The first discussion is free. The length depends on the file.
