Updated return — additional tax: how it works and FAQs

FY 2025-26 (Income-tax Act 1961) and FY 2026-27 (Income-tax Act 2025) · Updated

How it works

An updated return (section 139(8A)) lets you fix a missed or wrong return, but you pay extra tax under section 140B on top of the tax and interest due.

An updated return (section 139(8A)) lets you fix a missed or wrong return, but you pay extra tax under section 140B on top of the tax and interest due. The extra is 25% if you file within 12 months of the end of the assessment year, then 50%, 60% and 70% as you get later (and higher where the extended-rate conditions apply).

  1. Base = tax liability − TDS/TCS − advance tax − self-assessment tax − reliefs − tax credit + interest payable − refund already issued + late fee (not below 0).
  2. Additional tax = the rate for your time window × base.
  3. Total payable = base + additional tax.

Worked example

Total payable with the updated return = ₹1,00,000.

Tax liability ₹1,00,000, advance tax ₹20,000 already paid, filing within 12 months.

  1. Base = 1,00,000 − 20,000 = ₹80,000.
  2. Additional tax = 25% × 80,000 = ₹20,000.

Total payable with the updated return = ₹1,00,000.

Frequently asked questions

How much extra tax does an updated return cost?

25% / 50% / 60% / 70% of the tax-and-interest due, depending on how long after the assessment year you file.
