The National Board of Revenue (NBR) has introduced an online system allowing individual taxpayers to apply for an extension to submit their income tax returns for the 2025–2026 tax year.

The revenue authority has made online submission of income tax returns mandatory for most individual taxpayers, with a few exceptions.

According to the NBR, nearly five million individual taxpayers have already registered on its e-Return system, while around 4.1 million have submitted their returns for the current tax year.

The deadline for filing returns for individual taxpayers has been extended until 31 March 2026, the NBR said in a press release on Monday.

However, taxpayers who submit a written request before the deadline may receive an additional extension of up to 90 days, subject to approval by the respective tax commissioner.

To make the extension process easier, faster and more transparent, the NBR has launched a dedicated online facility within its e-Return system.

Taxpayers can now log in to the system and apply for additional time through the “Time Extension” menu. The concerned tax commissioner will review the application online and either approve or reject it.

If the request is approved, taxpayers will be able to submit their returns within the extended deadline without any penalty or additional tax, the NBR said.

However, taxpayers must be registered in the e-Return system and submit the extension request before 31 March 2026 to use the online facility.

Those taxpayers for whom online filing is not mandatory may apply for an extension either online or by submitting a written application directly to the relevant tax circle.

The NBR has urged all individual taxpayers to submit their income tax returns for the 2025–2026 tax year through the e-Return system by 31 March 2026, or within the additional time approved by the tax commissioner.
