In plain words: how far back the department can reopen a year depends on time limits that hinge on the amount involved — and they have changed.
The normal time limit
For ordinary cases, reassessment can generally be opened within a shorter period — broadly about three years from the end of the relevant assessment year.
The extended time limit
For serious cases — where the escaped income is large (commonly ₹50 lakh or more) and represented by an asset (or specified entries/expenditure) — the law allows a much longer look-back, historically up to ten years.
Why the amount matters
- It decides whether the longer window is available.
- Reopening a year beyond the shorter limit needs the high-value condition satisfied.
- So how the escaped amount is computed is often contested.
A moving target
Importantly, the exact limits have been revised by recent Finance Acts — including changes to the outer period and the conditions. So the precise time limit for your year must be checked against the current law.
Using time limits as a defence
- Check whether the notice is within the applicable limit.
- Contest the high-value condition for extended reopening.
- Raise limitation as a threshold objection.
