Everything you need to know about filing income tax returns in compliance with FBR — from NTN registration to sales tax returns and handling tax notices.

Filing income tax returns in Pakistan is a mandatory obligation for individuals, associations of persons (AOPs), and companies whose income exceeds the taxable threshold. The Federal Board of Revenue (FBR) has streamlined the process through its online IRIS portal, but the requirements and nuances can still be overwhelming for many taxpayers.

Who Needs to File?

Any individual with an annual income exceeding PKR 600,000, all registered companies, and any AOP regardless of income level are required to file income tax returns. Additionally, anyone who owns property worth PKR 5 million or more, owns a vehicle, or has a commercial electricity connection must file.

NTN Registration — The First Step

Before you can file, you need a National Tax Number (NTN). Registration is done online through the FBR IRIS portal. You will need your CNIC (for individuals), business registration documents (for companies), and bank account details. The NTN is your unique identifier in all tax-related matters.

Types of Income Tax Returns

For salaried individuals, the return includes salary income, property income, capital gains, and any other sources. For business individuals and AOPs, it includes business income, profit and loss statements, and balance sheets. Companies must file corporate returns with detailed financial statements, tax computations, and wealth reconciliation.

Key Deadlines

The standard deadline for filing income tax returns is September 30 of each year for the preceding tax year (July–June). Extensions are occasionally granted by the FBR, but relying on extensions is risky. Late filing attracts penalties and removes your name from the Active Taxpayers List (ATL).

Common Mistakes to Avoid

Underreporting income, failing to reconcile wealth statements, missing deductible expenses, and not maintaining proper records are the most common mistakes. Each of these can trigger an FBR notice and potential audit. Working with a professional tax consultant ensures accuracy and compliance.
