Dear Microsoft Support Team,

I am writing to request a Certification of Tax Residence for the Tax Year 2026 for the Microsoft Ireland Operations Limited that issues invoices for my account.

This document is required by my local tax authorities to apply the Double Taxation Avoidance Agreement and to justify the application of reduced withholding tax rates (or exemption) on payments made to Microsoft.

Please send the certificate in electronic form (PDF).

Best,
Damian
