The document checklist for filing a Pakistani tax return
The order of work on a Pakistani tax return matters more than the portal. Assemble the evidence first, reconcile second, file third. People who open IRIS first end up letting the screens dictate the sequence and plugging the gaps with estimates — and the estimates are what produce notices.
Group one: income evidence, by head
| Head | What to obtain |
|---|---|
| Salary | Salary certificate and tax deduction certificate from every employer for the year, including a previous employer if you changed jobs — multiple employers |
| Business | Accounts or a receipts-and-payments summary; sales and purchase records; the aggregate of your sales tax returns for reconciliation |
| Property | Tenancy agreements; rent received records; section 155 deduction certificates; property tax and insurance receipts — rental income |
| Capital gains | Broker or CDC statements with transaction detail and cost basis; property sale deeds with acquisition documents |
| Other sources | Dividend and profit-on-debt certificates; prize or commission records; pension documentation |
| Foreign income | Overseas income records, exchange rates applied, and evidence of receipt route |
Group two: tax already paid
Two separate things, both needed:
- Certificates and challans — withholding certificates by section, advance tax challans, and any instalments paid.
- FBR own record of tax deducted against your registration.
You draw a salary, tax is deducted at source every month, and you want the return filed properly without spending a weekend inside IRIS.
Group three: assets and liabilities at year end
Everything you own and owe on 30 June, with the acquisition history for anything new:
- Immovable property — deeds, acquisition dates and cost, advance tax challans, and the funding trail.
- Vehicles — registration documents, purchase price, advance tax paid.
- Bank balances at year end for every account, including dormant ones.
- Investments — shares, funds, certificates, prize bonds, with cost and current holding.
- Business capital and any receivables or loans given.
- Jewellery and specified personal assets.
- Foreign assets — property, accounts, investments, business interests.
- Every liability — bank borrowings, mortgages, personal loans, credit facilities, amounts payable.
Group four: the cash trail
The group that gets skipped and the one that decides whether the return reconciles:
- Complete bank statements for the full year, for every account. Not a summary, not the last three months.
- Records of gifts and inheritances received — who, when, how much, and the transfer evidence.
- Remittance evidence where funds came from abroad — remittance proof.
- Capital introduced or withdrawn from a business.
- An honest estimate of household expenses, built from actual spending rather than derived as the figure that makes the bridge close.
The five items always chased in September
The pack, by group and source
| Group | Documents | Comes from | Request by |
|---|---|---|---|
| Income evidence | Salary certificate, rent agreements, business accounts, broker statement | Employer, tenant, your books, broker | 31 July |
| Tax already paid | Sections 149, 151, 153, 155, 231B certificates and challans | Employer, bank, customers, excise office | 31 July |
| Assets and liabilities | Bank statements at year end, property deeds, vehicle books, loan statements | Banks, your own file | 15 August |
| The cash trail | Twelve months of bank statements, remittance certificates, gift documentation | Banks, remitters | 15 August |
Sort by the fourth column rather than the first. Everything in groups one and two depends on an institution responding to you, and every one of those institutions receives the same request from thousands of people in the same fortnight. Groups three and four are largely retrievable on demand — which is why they are the ones to leave until last, not first.
- The previous employer certificate. Request it when you leave, not eight months later.
- Bank statements for a closed account. Retrievable, but slowly and sometimes for a fee.
- Broker statements with cost basis for holdings acquired years earlier.
- Section 155 certificates from a corporate tenant whose finance team has moved on.
- Property acquisition documents for an asset bought long ago, from a developer that has since changed hands.
All five are avoidable with a mid-July request round. That single habit is the difference between filing in early September and filing on 30 September.
How to organise what you have gathered
A pile of correct documents that nobody can navigate is only marginally better than a missing one. Two conventions make the difference, and they take minutes to adopt:
- File by tax year, not by document type. Everything relating to the year ended 30 June belongs in one place — certificates, statements, deeds, challans, the computation and the filed return. Filing property documents in a property folder and bank statements in a banking folder means reassembling the year from scratch every time a question is asked about it.
- Name files so they sort usefully. Year, then type, then counterparty — so the folder reads in a logical order rather than alphabetically by whatever the bank called the download.
Then keep the pack with the return after filing. When a notice arrives two years later asking about one figure, the difference between an afternoon and a fortnight is entirely whether that year evidence still sits together. See what an audit asks for.
How long to keep it
Keep records long enough to defend the return through any assessment, audit, appeal or refund proceeding that could still be opened — which is frequently longer than a default retention period suggests. Two practical rules:
- Suspend any routine destruction entirely while a notice, audit or appeal is open for any year.
- Keep acquisition documents for as long as you hold the asset, plus the defence period afterwards. A deed from 2015 is still the cost basis for a gain computed in 2030 — property capital gains.
Readable electronic copies with their download trail are generally more useful than paper, provided they are backed up somewhere you will still have access to after a laptop or an accountant changes.
Then, and only then, reconcile
With all four groups assembled, build the wealth bridge from opening to closing net assets before touching the portal. If it does not close, the difference is a real transaction to trace, not a figure to adjust — the tracing method. Once it closes, the IRIS session becomes data entry. The filing sequence covers the rest.

Questions people also ask
My employer has not issued the tax deduction certificate. What do I do?
Request it in writing and keep the request. Payslips can support the salary figure in the meantime, but the certificate is what evidences the tax deducted, and you should also check whether the deduction appears against your registration in FBR records. If the deduction was never deposited, the certificate alone will not sustain the credit.
Do I need bank statements for accounts with almost no activity?
Yes, all of them. Dormant accounts are exactly where unexplained credits sit, and a reviewer will ask about an account that exists but was not reconciled. Completeness costs you an hour; an unexplained gap costs considerably more.
I cannot get statements for a closed account. Now what?
Approach the bank formally — closed-account statements are usually retrievable for a period, though there may be a fee and a delay. If they genuinely cannot be produced, document the attempt and reconstruct the position from whatever evidence exists. Do not simply omit the account, because its closing balance still has to be explained.
How far back do I need documents for a first return?
Further than one year. A first return establishes an opening asset position, and each of those assets needs a funding source you can evidence — which means reaching back to when they were acquired. This is the part of a first filing that takes the most time and the part most often skipped.
Is a broker statement enough for share transactions?
It is the starting point rather than the whole answer. You need the transaction detail, the tax deducted where applicable, and the cost basis for anything sold. Where holdings span several years, the cost history matters as much as the current-year activity, so retain the annual statements rather than only the latest one.
