Common Tax Mistakes in Pakistan — Top 10 Errors 2025
Every tax year, thousands of Pakistani taxpayers make mistakes that cost them money, trigger penalties, or delay refunds. Based on FBR audit findings and tax practitioner experience, here are the 10 most common tax mistakes and how to avoid them.
Mistake 1: Not Filing a Return at All
The Problem: Many people assume that if their employer deducted tax from their salary, they don’t need to file a return. This is incorrect. Filing a return creates a tax record that is essential for bank loans, visa applications, professional licensing, and maintaining filer status.
Solution: File a return every year, even if your tax was fully deducted. It takes only 15-20 minutes and provides long-term benefits.
Mistake 2: Filing Incorrect Financial Information
| Error | Consequence | Prevention |
|---|---|---|
| Wrong income figure | Tax demand or refund delay | Cross-check with salary certificate |
| Incorrect CNIC | Return rejected | Verify CNIC number before submitting |
| Wrong bank details | Refund not processed | Confirm IBAN with bank statement |
Mistake 3: Missing the Filing Deadline
The Problem: The September 30 deadline is firm. Late filing attracts penalties starting at PKR 1,500 per month. In the last week of September, the Iris portal often slows down due to high traffic, adding to the frustration.
Solution: File in August or early September. Set a calendar reminder for August 1 to start gathering documents.
Mistake 4: Ignoring the Wealth Statement Requirement
If your total assets exceed PKR 10 million, you must submit a wealth statement with your return. Many taxpayers skip this and face penalties of up to PKR 50,000 per year.
Mistake 5: Not Claiming Eligible Deductions
Many taxpayers forget to claim deductions they are entitled to — Zakat, charitable donations, pension fund investments, and health insurance premiums. This results in paying more tax than necessary.
Mistake 6: Keeping Inadequate Records
The FBR can audit returns filed up to 6 years ago. Without proper records (salary certificates, deduction proofs, bank statements), you may be unable to justify your declared figures during an audit.
Mistake 7: Mixing Personal and Business Finances
For freelancers and business owners, using a personal bank account for business transactions creates confusion and makes tax filing difficult. Open a separate business bank account from day one.
Mistake 8: Underreporting Income
Deliberately underreporting income is tax evasion and carries severe penalties — up to 200% of the tax involved plus potential criminal prosecution. The FBR has data-sharing agreements with banks, NADRA, and property registries to cross-verify income declarations.
Mistake 9: Not Checking Withholding Tax Deductions
Your employer and banks deduct withholding tax on your behalf. Always verify that the deductions reflected in your Iris portal match your actual deductions. Discrepancies can lead to tax demands.
Mistake 10: Ignoring Notices from FBR
If the FBR sends a notice or tax demand, ignoring it will not make it go away. Penalties and interest continue to accrue. Respond promptly, either by paying the demand or filing an objection with supporting documents.

Frequently Asked Questions
Can I correct a mistake in a filed return?
Yes. You can file a revised return within 90 days of the original filing. After that, amendments may require Commissioner approval.
What if I realize I made a mistake after receiving a refund?
You should voluntarily notify the FBR and repay any excess refund with interest. Voluntary disclosure is treated more leniently than discovery through audit.
