Certification of Tax Residence for the Tax Year 2026

Hello Pawel,

Thank you for using our Microsoft Advertising Learn Q&A Platform! 

I understand that you require a Tax Residency Certificate. I have provided the 2026 form by sending you a private message. You can check your private messages by clicking on "View messages" at the top of the page.

Please note that tax or VAT requirements depend on your business location, which is the country/region where your business is legally registered. (If you are an agency, it is the country/region where your client's business is legally registered.) You can select your billing location from the list on the help pages below to find specific tax information.

Tax or VAT information

Microsoft Advertising cannot provide guidance on tax or VAT. Please contact your tax advisor or local tax office if you have questions.

Microsoft Advertising is required to collect value-added tax (VAT) in certain countries/regions, and so all advertisers must provide the business location for each of their accounts. All Microsoft Advertising customers need to have a business location listed for each of their accounts. Business location is the country/region where the advertiser's business is legally registered. Whether you will be charged VAT on your advertising costs will depend on your business location and your tax registration status. For example, if you are in a business location that has VAT accounting obligations, you will need to enter your VAT registration number. If you do not provide your VAT registration number, Microsoft Advertising will charge VAT, in most cases. VAT will be charged based on your local rate. For more specific details and steps, kindly check the help page below:
