Thank you for posting in Microsoft Q&A forum

As per Microsoft’s billing policy for India, GSTIN must be added to the billing profile before the invoice is generated. Once an invoice has been issued, Microsoft does not support reissuing or revising invoices to add GSTIN retroactively.

Unfortunately, for purchases already completed (including Microsoft 365 Family bought using a personal Microsoft account), it is not possible to add GSTIN or obtain a revised GST invoice after the purchase date.

GSTIN can only be applied to future purchases or renewals after updating the billing tax information in advance.

Thank you for your understanding
