Pakistan Tax Filing Guide 2026

Annual ITR — September 30 (Individuals), December 31 (Companies)

The tax year in Pakistan runs from July 1 to June 30. The annual income tax return (ITR) filing deadlines are: September 30 for individuals (including AOPs) and December 31 for companies. These deadlines apply to the tax year ending the previous June 30. Extensions are sometimes granted through the Finance Act. The return must include all sources of income (salary, business, capital gains, rental, foreign), deductions, tax credits, and the wealth statement (including foreign assets). Filing is mandatory for all individuals earning above the tax-free threshold (PKR 600,000 for salaried individuals).

Sales Tax Returns — Monthly/Quarterly

Registered persons must file sales tax returns on a monthly basis (by the 18th of the following month). Certain small taxpayers may file quarterly returns. The return includes: output tax charged on supplies, input tax claimed on purchases, net tax payable or refundable, and supporting schedules (invoices, adjustments). The return is filed electronically through the FBR's IRIS portal. Late filing attracts a penalty of PKR 10,000 plus PKR 100 per day of delay. Default surcharge of 1% per month applies on unpaid tax.

WHT Returns — Monthly (CPR)

Withholding tax agents must file a Monthly Withholding Tax Statement (CPR — Computerized Payment Receipt) through the IRIS portal. The CPR includes: details of tax deducted from payments (salary, contracts, rent, dividends, interest, etc.), tax deposited with the FBR, and challan details. The CPR is due by the 15th of the following month. Annual WHT statements (annual returns) are also required for certain categories. Failure to file CPRs can result in penalty of PKR 5,000 per month and disallowance of expense deductions.

eFiling via Iris (FBR Portal)

All tax filings in Pakistan are done electronically through the FBR's IRIS (Integrated Risk Information System) portal at iris.fbr.gov.pk. IRIS is a comprehensive online platform for: income tax return filing, sales tax return filing, withholding tax statements (CPR), tax payments (integration with bank challans), taxpayer profile management, correspondence with the FBR, and refund tracking. The portal uses a user-based system where each taxpayer has a unique login. Filing requires a valid NTN (National Tax Number) and active registration. The system provides pre-populated data for salaried individuals (employer-reported data) and tracks taxpayer compliance status (ATL — Active Taxpayer List).

Withholding Agent Requirements

Companies and certain individuals are required to act as withholding agents under Pakistan's tax system. Key obligations: deduct tax at prescribed rates on payments (salary, contracts, rent, dividends, interest, fees, commissions, imports), deposit the deducted tax with the FBR within the prescribed time (usually within 15 days of deduction), issue withholding tax certificates (Form 16A) to the payee, and file monthly CPRs. Failure to deduct or deposit WHT can result in: disallowance of the expense for tax purposes, recovery of the tax from the withholding agent, penalties, and prosecution. The FBR actively monitors WHT compliance through its computerized system.

Penalties — 2%/Month Late Filing

Pakistan imposes significant penalties for non-compliance. For late filing of income tax returns: a fixed penalty of PKR 10,000-50,000 (depending on taxpayer category) plus a default surcharge of 2% per month (or part thereof) on the unpaid tax amount. For non-filers: the FBR can block the taxpayer's NTN (making it inactive), impose higher withholding tax rates on banking transactions and property purchases, restrict bank account operations, and file prosecution cases for persistent non-compliance. Filing after the deadline also means losing ATL (Active Taxpayer List) status, which results in higher withholding tax rates throughout the following year.

Registration for Non-Filers — Inactive NTN

Taxpayers who have an NTN but fail to file returns for consecutive years may have their NTN marked as inactive by the FBR. Consequences of an inactive NTN include: inability to file returns until reactivation, higher withholding tax rates on banking transactions and purchases, potential blockage of bank accounts, and inclusion in the public "Non-Filer" list. Reactivation requires filing all outstanding returns and paying applicable penalties. The FBR has also blocked mobile SIM cards for certain non-filers in high-profile enforcement drives. The government has used the tax directory (public list of filers and non-filers) as a social pressure mechanism to encourage compliance.

FAQs

Can I file my tax return myself?

Yes, the IRIS portal is designed for self-filing. Many salaried individuals file their own returns using pre-filled salary data. However, business owners, property investors, and individuals with complex income sources typically use tax practitioners. The FBR also offers mobile apps for return filing.

What documents do I need to file a tax return?

Key documents include: salary certificates (from employer), bank statements, withholding tax certificates (Form 16A from all deductors), details of investments (for tax credits), details of foreign assets, and property documents. The IRIS system pre-fills certain data.

What is the Active Taxpayer List (ATL)?

The ATL is a list of compliant taxpayers published by the FBR. Taxpayers on the ATL benefit from lower withholding tax rates (e.g., 0.3% vs 0.6% on cash withdrawals). Non-filers face significantly higher rates. The ATL is updated annually based on return filing status.
