When you file an ITR-U (Updated Return), the Income Tax Department recalculates your tax liability, including all interest and additional charges up to the date of filing. In your case, your CA underpaid ₹70,000, and the system added interest for the extended period.
Even though you filed in May 2024, the Department seems to have calculated interest till November 2025, which appears unusual and needs review.
How Is Interest on ITR-U Usually Calculated?
Interest under an updated return generally includes:
1. Interest under Section 234A, 234B, 234C
Calculated from the original due dates until the tax is fully paid.
2. Additional ITR-U Fee (25% or 50%)
If filed within 12 months → 25% extra
If filed between 12–24 months → 50% extra
3. Interest on Broken Period
As your ITR-U document states:
“Where taxes are paid in parts before the filing of the updated return, the interest shall be computed for the broken period…”
This means interest should ideally apply only until the date of each tax payment, not till Nov 2025.
So your estimation:
₹70,000 × 18% ≈ ₹83,000
is reasonable if no other components are missing.
A 1.3 lakh demand suggests either:
The portal added 25% or 50% additional tax, or
One or more interest sections were recalculated, or
There is an error in the computation.
What Should You Do Next?
1. Download the Complete Computation Sheet
Go to:
Income Tax Portal → e-File → Income Tax Returns → View Filed Returns → ITR-U → Download ‘Computation’
Check for:
25%/50% additional tax
234A/B/C interest breakup
Any overlooked income or mismatch
2. Compare the Department’s Figures with Your CA’s Computation
Verify each interest section
Confirm whether interest is correctly added only till May 2024
Check if any tax credit was missed (e.g., TDS not claimed)
3. Raise a Grievance if the Calculation Is Wrong
Use:
Portal → Helpdesk → Raise Grievance → Under ‘Updated Return / Demand’
Attach:
Your ITR-U
Your CA’s working
Explanation of incorrect interest till Nov 2025
The team usually responds within a few days.
4. If the Demand Is Correct, Pay Early
If after checking, the demand is correct:
Pay it as soon as possible to avoid further interest.
Use Challan 280 → Self-Assessment Tax.
5. Speak to Your CA Immediately
A miscalculation of ₹70,000 is serious.
Ask for:
A corrected computation
A written explanation
Possible fee reduction or compensation for their mistake
Should You Panic?
No. These issues are common with ITR-U filings.
If interest is wrongly calculated till Nov 2025, it can be corrected.
You just need to verify the computation and escalate if needed.
You’re not alone — many taxpayers face similar issues every year.
