Frequently Asked Questions
Can I file after the October 15 deadline?
Yes, but you'll pay penalties based on how late you file. The penalty remission schedule applies if you file within 3 months. File as soon as possible to minimize penalties.
What if I have zero tax liability?
You still need to file a return if you meet filing requirements. This maintains your ATL status and provides proof of income for various purposes.
Can I amend my return after filing?
Yes, you can file a revised return within 60 days of original filing, or an amended return within 5 years. However, amendments may trigger FBR scrutiny.
Do I need a tax consultant?
For simple salaried income with no other sources, you can file yourself. Use our tax calculator to verify amounts. Complex cases with multiple income sources or business income may benefit from professional help.
What's the difference between Active Filer and Late Filer?
Active Filers file before the deadline and enjoy lowest tax rates. Late Filers who file after the deadline face higher withholding taxes (often 6% vs 3% on property) even after filing. The difference can cost thousands on major transactions.
