A Tax Residency Certificate for Microsoft Ireland Operations Limited (MIOL) is published by Microsoft as part of the common tax forms used to set Microsoft up in Accounts Payable systems.

For MIOL, the available certificates are listed under “Microsoft Ireland Operations Limited (MIOL)” in the common tax forms section. The documentation currently shows certificates for recent years (for example, “Certification of Tax Residence” and a “Notarial Certificate”). For a 2026 Tax Residency Certificate specifically, if it is not yet listed in that section, it is not available in the provided documentation.

To obtain or confirm availability of the 2026 Tax Residency Certificate for MIOL for Polish withholding tax purposes:

1. Check the latest “Certification of Tax Residence” for Microsoft Ireland Operations Limited (MIOL) in the common tax forms list.
2. If the 2026 certificate is not yet posted, contact Microsoft through Partner Center or your usual Microsoft account/billing channel and request the latest Tax Residency Certificate for MIOL, specifying that it is required for Polish withholding tax.

These certificates are the standard documents used globally (including for Poland) to support treaty‑based withholding tax relief.
