"Amendment of assessment" sounds bureaucratic, but in plain terms Section 122 of the Income Tax Ordinance 2001 is simply the legal tool FBR uses to go back and change a tax return after it's already been processed. It can apply to a return you self-assessed years ago, and it usually means the Commissioner thinks you owe more tax than you originally reported.
What Puts a Return on FBR's Radar
| Trigger | What FBR Sees |
|---|---|
| Bank data mismatch | Deposits or transfers larger than declared income |
| Property registrar records | A purchase or sale not reflected in your wealth statement |
| Expense ratio flags | Business costs that look unusually high against reported revenue |
| Cross-year comparison | Wealth statement growth that outpaces the income you declared |
The Legal Time Limits FBR Works Under
FBR generally has five years from the end of the tax year in which a return was filed to amend it. That window stretches further — effectively without a hard limit — where fraud or deliberate concealment is alleged. This is one reason keeping six years of supporting records (bank statements, invoices, salary certificates) is worth the minor hassle: it's your evidence bank if an old return ever gets reopened.
What a Notice Actually Asks For
Rather than simply announcing a decision, Section 122 notices are "show cause" in nature — FBR proposes a change and gives you a defined window, generally 30 days, to argue against it before the amendment is finalized. Ignoring the notice does not preserve the status quo; the Commissioner proceeds and the amended assessment stands, typically with added tax, penalty, and default surcharge on top.
Responding Without Losing the Thread
- Identify precisely which income item, deduction, or figure is disputed and for which tax year
- Pull together bank statements, contracts, receipts, and salary certificates covering that period
- Reply in writing, addressing each point FBR raised individually rather than in general terms
- Submit through IRIS correspondence or by courier to the RTO with acknowledgment
- If a hearing is scheduled, attend with all originals and, ideally, a consultant
If You Disagree With the Final Outcome
An unfavourable amendment order is not the end of the road. You can appeal to the Commissioner (Appeals) within 30 days, escalate to the Appellate Tribunal Inland Revenue if needed, and take pure legal questions to the High Court. Each stage has its own filing clock, so speed matters more than perfection in the early stages.
