Request for Singapore Certificate of Tax Residence (COR) 2026 - Microsoft Regional Sales Pte. Ltd.

The 2026 Certificate of Tax Residence for Microsoft Regional Sales Pte. Ltd. must be provided through a private support channel because Microsoft does not publish this document as a public download.

Microsoft Q&A has confirmed that the 2026 Singapore certificate for Microsoft Regional Sales Pte. Ltd. is available and has been delivered to requesters through a private-message banner.^1^ Similar requests are handled privately because the document cannot be shared publicly.^2^

Request the Thailand-specific document

Since the destination jurisdiction can determine which documentation is appropriate, include all of the following in the request:

• Legal entity: Microsoft Regional Sales Pte. Ltd.
• Tax year: 2026
• Country where it will be submitted: Thailand
• Purpose: withholding-tax compliance and Singapore–Thailand treaty benefits
• Relevant Microsoft invoice number and billing-account details
• Request for a secure PDF or private download link

Watch this Q&A thread for a private-message banner and enable its notifications. Do not post invoices, account identifiers, tax numbers, or contact details publicly.

If no private message arrives

A Microsoft 365 administrator should open a business billing support request:

1. Sign in to the Microsoft 365 admin center.
2. Select Help & support at the lower-right.
3. Enter:
   Request 2026 Singapore Certificate of Tax Residence for Microsoft Regional Sales Pte. Ltd. for withholding-tax treaty use in Thailand
4. If the suggested results do not resolve the request, select the Contact Support headset icon.
5. Choose phone or email, provide the requested contact details, and submit the case.

This support route requires an administrator and at least one subscription purchased directly through Microsoft. If all subscriptions were purchased through a partner, contact that partner instead.^3^

A normal invoice download is not a substitute for the COR: the Microsoft 365 admin center’s Billing → Bills and payments area provides invoices, whereas the residency certificate must be requested separately through the private/support process.^4^
