Filing income tax return is our national responsibility. Taxes are main source of income for any country. Besides legal requirement, it is our responsibility towards our country to pay taxes if it is payable on us. This liability of tax payment is determined in tax returns. That is why we should file our income tax return. 

Section 114 of Income Tax Ordinance provides a list of people who are legally bound to file their income tax return. Law binds every one who is earning income above the exempted limit annually. Besides that any person who is paying tax under any provision of law is liable to file his income tax return. This includes every one who pays Withholding Tax (WHT) on any transaction during a tax year. This section also binds owner of property over 4 Marlas to file income tax return.

Filing income tax return makes you appear as Active Filer in FBR’s Active Taxpayer List (ATL). This enables you to save Withholding Tax (WHT) on many transactions such as purchase of vehicles, bank profits, purchase or sale of property and many more.

Yes FBR lets you claim tax refund if it is applicable. But there are certain requirements for it. Most important is to file Income Tax Return within due date each year.
