B2BA - Business-to-Business Amendment
B2BA refers to Business-to-Business Amendments under GST for supplies made to registered recipients. It involves adjusting and reporting changes in previously issued invoices to registered entities, where the tax liability was initially declared under B2B transactions. This could include corrections related to the value, tax rate, or any other details in the original document, such as credit or debit notes issued. It is essential for maintaining accurate records of taxable transactions, ensuring compliance with GST provisions, and providing the necessary amendments in the GST return for proper tax adjustments. These changes are reported to both the supplier and the recipient.
