    For an existing invoice, the GSTIN can't be added after the invoice has already been generated.

    For future Microsoft 365 purchases or renewals, add the tax ID in advance in the Microsoft 365 admin center:

    • For an MCA billing account: Billing > Billing accounts > select the billing account > Add tax ID > enter the GSTIN > Save.
    • For a MOSA billing account: Billing > Your products > select the subscription > Service usage address > Edit service usage address > enter the GSTIN in VAT, GST, or PAN number > Save.
