Taxpayer who never filed ITR for a particular year — even though income exceeded basic exemption limit — can now file ITR-U within the 2-year window.
Taxpayer who forgot to include bank interest, capital gains, freelance income, rental income — can update it using ITR-U.
If excess deductions u/s 80C, 80D, HRA, etc. were claimed by mistake — ITR-U allows correction by paying correct tax.
Professional income reported as other sources instead of business/profession — can be corrected through ITR-U.
Filed ITR-1 but had capital gains requiring ITR-2 — can file ITR-U under the correct form.
ITR-U CANNOT be used to claim a refund or to increase a refund already claimed. Use revised return u/s 139(5) instead.
ITR-U can ONLY result in equal or higher tax liability. You cannot reduce previously assessed tax or claim additional deductions.
If Income Tax search u/s 132 or survey u/s 133A has already been conducted for the relevant AY — ITR-U cannot be filed.
If prosecution has been initiated u/s 276C or 276CC for the relevant year — ITR-U cannot be filed.
If notice for assessment u/s 143(2) or reassessment u/s 148 has been issued — ITR-U cannot be filed.
Once filed, it cannot be revised or filed again. Make sure disclosure is complete before submission.
ITR-U must be filed within 2 years from the end of the relevant Assessment Year. The additional tax payable depends on HOW LATE the ITR-U is filed:

Additional Tax = 25% of (Tax Payable + Interest u/s 234A/234B/234C)
Example: Tax due = ₹50,000 + Interest = ₹10,000. Additional Tax = 25% of ₹60,000 = ₹15,000. Total = ₹75,000
Additional Tax = 50% of (Tax Payable + Interest u/s 234A/234B/234C)
Example: Tax due = ₹50,000 + Interest = ₹10,000. Additional Tax = 50% of ₹60,000 = ₹30,000. Total = ₹90,000

ITR-U cannot be used to claim refunds. Use revised return u/s 139(5) if still within time.
ITR-U is defective if additional tax u/s 140B is not paid before submission.
Only ONE ITR-U is allowed per AY and it cannot be revised. Double-check AY before submitting.
Missing the 2-year deadline permanently closes the ITR-U window for that AY.
Partial disclosure defeats the purpose. If department detects remaining income, protection may not apply.
Incorrect interest calculation leads to short payment — making return defective.
