GSTN Introduces Automated Annexure-B Validation Utility for GST Refund Claims Under Form RFD-01
Overview of the New Development
The Goods and Services Tax Network (GSTN) has rolled out a significant upgrade to the GST refund filing ecosystem by deploying an automated validation utility specifically designed for Annexure-B (ITC Statement), which is required to be submitted alongside Form RFD-01. This development represents a fundamental shift in how refund applications are prepared, validated, and processed on the GST Portal.
Previously, assessees and their consultants were preparing Annexure-B independently — either in PDF or Excel format — and uploading it as a supporting attachment at the time of filing the refund application. Under the revised framework, this approach has been entirely discontinued. The utility now mandates that Annexure-B be prepared exclusively through the officially prescribed validation tool and submitted in JSON format, which is then directly integrated with the refund application on the portal.
What Has Actually Changed — Not Just a Format Shift
It is important to understand that this transition is far more than a mere conversion from PDF to JSON format. It represents a complete paradigm shift toward a system-driven, validation-based refund processing mechanism.
The automated utility performs a series of pre-submission checks and validations, ensuring that the data entered by the assessee meets the prescribed standards before the refund claim can proceed further. This eliminates the possibility of uploading unverified or inconsistent data, which was a significant limitation of the earlier manual approach.
GSTN's underlying objective behind this transition is multi-pronged:
- Enhancing transparency in the ITC refund claim process
- Minimising the need for manual departmental scrutiny
- Improving accuracy and consistency in the data submitted with refund applications
- Facilitating data-centric verification at the processing stage
Key Features and New Reporting Requirements Introduced
1. Mandatory Disclosure of Blocked ITC Under Section 17(5) of the CGST Act
One of the most notable additions in the updated utility is the requirement to separately report Input Tax Credit that is blocked under Section 17(5) of the Central Goods and Services Tax Act. This ensures that assessees cannot inadvertently include ineligible credits within their refund claims without explicit disclosure, and it enables the system to flag or exclude such credits at the validation stage itself.
