Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear Shubham,
I understand you specifically require the 2025 and 2026 Certificates of Tax Residence for Microsoft Regional Sales Pte Ltd in Singapore, rather than certificates for another Microsoft entity. For this specific request, I recommend having your Global Administrator or Billing Administrator open a service request with Microsoft Billing Support through Microsoft 365 admin center > Help & support. Billing Support is the appropriate team to confirm whether these certificates are available and provide the applicable tax documentation for the Microsoft entity associated with your billing relationship. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support
I hope this helps. Let me know if you need anything else. Have a wonderful day.
