Introduction
Form No. 146 replaces Form 15CB as part of a major compliance transition under Section 393 of the Income-tax Act, 2025 read with Rule 220 of the Income-tax Rules, 2026.
This change is not merely procedural. It introduces enhanced disclosure, stricter validation, mandatory UDIN integration, and a structured pre-filing workflow, making foreign remittance certification more accountable and audit-ready.
Form 146 is mandatory for foreign remittances exceeding ₹5 lakh to non-residents and must be obtained prior to remittance.
What is Form 146
Form 146 is a Chartered Accountant certificate required to determine taxability, applicable withholding tax, and DTAA eligibility for foreign remittances. It replaces Form 15CB and is a pre-condition for remittance through authorised dealer banks.
