What an FBR audit actually asks for, in order
An audit is a tracing exercise. The reviewer is testing one proposition: that the figures in your filed return can be followed back to your ledgers and from there to source documents. Everything that makes an audit painful comes from records that cannot support that journey.
The core document set
Assemble these regardless of what the notice specifically lists, because they will be needed:
| Category | Documents |
|---|---|
| Filings | The return as submitted, the computation, the wealth statement, and the acknowledgement — for the year under audit and the year before it |
| Financial records | Financial statements, audited where applicable; trial balance; general ledger; fixed asset register with acquisition dates and cost |
| Banking | Complete statements for every account for the full period, including accounts with little activity |
| Sales | Sales register by invoice; the invoices themselves; credit notes; the sales tax returns and annexures for all twelve months |
| Purchases | Purchase register; supplier tax invoices with valid registration particulars; import documents |
| Withholding suffered | Certificates by section, matched to the credits claimed and to FBR records |
| Withholding deducted | Challans, statements filed, certificates issued, and the dated ATL checks that supported the rates applied |
| Payroll | The section 149 computation per employee, not just the deduction total — section 149 |
| Assets and property | Acquisition deeds, payment evidence, advance tax challans, funding trail |
The four reconciliations tested first
These are where audits start, because a break in any of them points straight at the issue:
- Sales tax turnover to income tax turnover. Twelve months of returns against the annual figure. Legitimate differences exist — exempt supplies, timing, non-taxable income — but each has to be identified and explained from the records.
- Bank to ledger. Every account, every month. Unreconciled movement is the most productive place for a reviewer to look.
- Withholding claimed to FBR records. Certificates alone are not enough if the tax was never deposited against your registration.
- The wealth bridge. Opening net assets to closing net assets, with every material movement traced — the tracing method.
A notice landed in your IRIS inbox or by post, there is a date on it, and you do not know what it is asking for.
Building an issue-evidence file
Do not hand over a box of documents. Structure the production so each issue raised has its own answer:
- Issue as the notice describes it.
- Your position in one or two sentences.
- The documents establishing it, named and dated, cross-referenced to the attachment.
- Any gap, identified honestly, with the best alternative evidence.
The gap column is the one that determines your strategy. Where there are none, the audit is a production exercise. Where there are several, you need advice before responding rather than after. Responding to a notice covers the method in full.
Managing the process
- Diarise the response date the day the notice arrives, and work to two days before it.
- Request more time before the deadline if you need it, with a reason and a date. Not afterwards.
- Respond in writing through the prescribed channel, so there is a timestamped record. Avoid resolving points by informal conversation.
- Stay within scope. Produce what is requested for the periods raised, nothing more.
- Keep a register of every document produced, when and in response to which request.
- Do not reconstruct or backdate anything. A missing record is a manageable problem; a fabricated one is not.
The five issues that consume most of an audit
Audits rarely range freely across a whole return. In practice the time goes on a small number of areas, and knowing which lets you prepare properly rather than broadly:
| Issue | What resolves it |
|---|---|
| Unexplained increase in assets | The wealth bridge with every movement traced to a document, and funding sources identified |
| Expenses claimed without adequate documentation | Supplier tax invoices with valid registration particulars, matched to payments |
| Expenses where withholding was not deducted | Challans and statements — a withholding lapse can make the expense itself non-deductible |
| Turnover understatement | The reconciliation between sales tax returns, the ledger and the income tax return |
| Withholding credits claimed | Certificates plus confirmation the credit appears against your registration in FBR records |
Note that three of the five are documentation questions rather than disputes about the law. That is characteristic: most audit adjustments arise because something could not be evidenced, not because the treatment was wrong. It is also why the remedy is largely administrative — the file either exists or it does not, and it cannot be created after the notice arrives.
The version of this that never happens
Audits are far less painful for businesses that maintain the file continuously rather than assembling it under a notice. Concretely: reconcile bank and ledger monthly, maintain the turnover reconciliation as you file each sales tax return, collect withholding certificates as they are issued, retain the dated ATL check with each payment voucher, and file acquisition documents by tax year.
Poor documentation — missing statements, unmatched credits, no turnover reconciliation — is itself among the most common reasons an audit notice is issued in the first place. Bookkeeping that survives a review covers how to build it, and if your records are behind, we can tell you what getting current involves.

Questions people also ask
Why was I selected for audit?
Selection is driven partly by risk parameters and analytics rather than at random. The recurring triggers are an unexplained increase in assets, household expenses inconsistent with declared lifestyle, a mismatch between sales tax turnover and income tax turnover, withholding claimed that does not appear in FBR records, and third-party data showing transactions absent from your declarations. If you can identify which applies, you can predict what will be asked.
Should I provide more than what is asked for?
No. Produce what is requested, completely and legibly, within scope. Volunteering documents for periods or issues not raised expands the enquiry and gives the reviewer material to work with that they had not asked for. Being cooperative means being responsive and complete on the scope, not being expansive beyond it.
What if some records are genuinely missing?
Say so, explain why, and produce the best alternative evidence available — bank records, third-party confirmations, correspondence. An honest account of a gap, with substitutes, is a far better position than a reconstructed document. Fabricating or backdating anything converts a documentation problem into something much more serious.
Can I handle an audit myself?
A narrow query about one figure, yes. A full audit covering a business year is a different matter, because how the file is presented and how each issue is framed shapes the outcome and any subsequent appeal. Representation also insulates the process from being conducted through informal conversation, which rarely helps the taxpayer.
How long does an audit take?
It varies with scope, the quality of your records and how many rounds of questions are needed. The single biggest factor within your control is the completeness of the first production. A file that answers the request in full without prompting follow-up questions shortens the process more than anything else you can do.
