Schema Validation in GSTR-9 

Schema Validation in GSTR-9 

Schema validation in GSTR-9 refers to the process of verifying the structure and format of the data entered in the return against the predefined schema provided by the GSTN. This validation ensures that the data conforms to the required standards, including correct field formats, mandatory fields, and logical consistency. If the data fails to meet these criteria, the system generates a schema validation error, preventing the submission of the return.

You can use schema validation to check if the entered data on the GST portal is correct and follows the format mentioned on the portal. In case of discrepancies, you will find a schema validation error code. You need to rectify the details to proceed with the GSTR-9 application.

Reasons for Schema Validation Failure in GSTR-9

  1. Schema validation error can inspire the wrongful or non-standard format of a GSTIN. Every GSTIN should conform to the basic 15 characters.
  2. The format of dates is another item; dates must be filled in the prescribed format (dd/mm/yyyy), as alternative formats may face rejection through the validation mechanism.
  3. Invalid HSN Codes must be supplemented by the latest and correct HSN codes. Using older or incorrect HSN codes leads to errors. Inconsistent data across sections.
  4. Discrepancies across different sections of the returns, such as mismatched figures of Table 6 and Table 8 would lead to validation errors.
  5. Exceeding the allowed length for fields entering values that exceed the allowed characters or digits in fields leads to a schema validation failure.
