Contact Microsoft Billing Support for a Tax Adjustment

Reach out directly to Microsoft's support team to request a review of your recent payments and ask for a sales tax refund.

Refunds for past tax charges covering several years are not guaranteed because the sold-to address permanently affects historical tax records. However, support agents can often review and adjust the most recent payments.

Visit Microsoft Support

Navigate to the official Microsoft Support Contact Us page (support.microsoft.com/contactus) in your web browser.

Select Your Product

Click on 'Microsoft 365' and then choose the 'Home support' option.

Frequently Asked Questions

Why did Microsoft charge me the wrong sales tax?

Microsoft calculates sales tax based on the 'sold-to' billing address on file in your account at the time of renewal. If you moved and did not update this address, the tax rate of your old location was automatically applied.

Will Microsoft regenerate my past invoices with the correct tax?

Generally, past invoices cannot be regenerated because the historical sold-to address has already been permanently recorded for legal tax compliance purposes. Refunds for older charges are rare.

How do I update my Microsoft billing address to prevent future issues?

Sign in to your Microsoft account online, navigate to the 'Payment & billing' section, and select 'Address book' to edit, update, and save your current billing address.
