Income Tax Return Deadline in Bangladesh: Tax Day, Extensions & Penalties

In Bangladesh, the statutory filing deadline for individual taxpayers is known as Tax Day, set by default on 30 November each year. Corporate entities must file by the 15th day of the seventh month following the end of their income year or 15 January. Missing deadlines without formal approval incurs severe statutory interest and penalties.

Statutory Rule: Under Section 174 of the Income Tax Act 2023, failing to submit your return on or before Tax Day incurs simple interest of 2% per month on the net payable tax for up to 24 months.

How to Apply for a Time Extension (Section 173)

If unforeseen events (such as illness, foreign travel, or delayed accounting records) prevent timely filing, submit Form IT-113 to your Deputy Commissioner of Taxes (DCT) before Tax Day expires:

  • State valid factual reasons for the requested delay.
  • Estimate total taxable income and deposit advance tax (AIT) or self-assessment tax.
  • Receive formal approval extending the submission period by up to two months (extendable up to four months with Joint Commissioner approval).

Consequences of Unauthorized Late Filing

  • Loss of allowable investment tax rebates under Section 78.
  • Ineligibility for universal self-assessment benefits.
  • Disallowance of carried-forward business or capital losses.
  • Exposure to penalty proceedings under Section 266.
