For Maharashtra VAT return (Form 231) under the new automation, the "Invalid transaction code" error usually happens due to:
Incorrect Transaction Code: Make sure you are using the exact transaction codes prescribed for inter-state sales in Maharashtra VAT system. Sometimes, codes differ for interstate vs intrastate sales.
Mismatch in Annexure Details: Check if all fields like invoice number, date, party GSTIN, taxable amount, and transaction code align properly. Even one wrong entry can trigger validation errors.
Software Version Issue: Sometimes the offline utility or portal version has bugs. Ensure you have the latest version of the return filing utility downloaded from the Maharashtra VAT website.
Cross-check GSTIN/UIN: For interstate sales, correct GSTIN or Unregistered dealer’s UIN should be entered.
Steps you can take: Review Maharashtra Commercial Tax Department website for updated transaction codes list.
Validate data in a separate Excel or CSV file before uploading.
Try reinstalling or updating the return filing software.
If issue persists, contact Maharashtra VAT helpdesk or use their online portal support.
