Frequently Asked Questions

Why do I need a Microsoft W-9 form?

A W-9 form is required by the IRS for US businesses to keep on file for vendors they pay. You need Microsoft's W-9 to legally verify their Taxpayer Identification Number (TIN) before processing their invoice and issuing payment.

Can I download the Microsoft W-9 form directly from their website?

No, Microsoft generally does not host their current W-9 form for public download due to security and vendor verification policies. You must request it directly through their billing support or via the admin portal.

What happens if I pay a Microsoft invoice without having their W-9 on file?

While payment will still go through to Microsoft, your own business's accounting department may be out of compliance with IRS regulations regarding vendor payments, which could complicate your annual tax reporting.
