Self-Assessment Tax

Tax paid by taxpayer at the time of filing ITR after accounting for TDS and advance tax.

Full Definition

Self-assessment tax is the remaining tax liability paid by the taxpayer at the time of filing the ITR, after deducting TDS already deducted and advance tax already paid. It is paid using Challan 280 on the income tax e-filing portal. Interest under Section 234A is payable if the return is filed after the due date, and Section 234B applies if advance tax was less than 90% of assessed tax. Pay self-assessment tax before filing to avoid a defective return.
