Finin2min Tax Desk·June 2026·7 min readTAX PAYMENT

Self-assessment tax is the final bridge between your computed tax liability and the return you file. If the challan is missing, wrongly mapped or not reflected in the return, you may get avoidable demand or refund delays.

When self-assessment tax arises

Self-assessment tax generally arises when tax payable after considering TDS, TCS, advance tax and reliefs still remains before filing the return. Official Schedule IT guidance captures tax-payment details such as advance tax and self-assessment tax.
