Form 51 User Manual Income Tax Act 2025

1. Overview

Transfer pricing can create uncertainty when international transactions are involved, as the price must be at arm’s length to avoid future disputes. To provide certainty in advance and reduce litigation, the Income Tax Department allows taxpayers to enter into an Advance Pricing Agreement (APA) for such transactions.
Form 51 is the application used to request an APA. It can be filed for a unilateral, bilateral, or multilateral agreement, along with the prescribed fee. The same form also allows the applicant to request rollback, so that the agreed approach can be applied to earlier years, wherever permitted by the rules.
Form 51 should be filed before the start of the first relevant tax year in case of ongoing transactions, or before undertaking the transaction in respect of remaining transactions. It must be submitted to the appropriate authority based on the type of APA being sought.

Form 51 is available on the incometax efiling portal and can be submitted online only.
