Hello,
Welcome to Microsoft Q&A!
Recently there are some customers meeting the issue about can't not updating the tax profile. I fully understand your feelings. Could you please try the following steps to try again?
- Use the latest Edge version on Windows 10
- Ensure that your browser language is set to en-US (English American)
- Open an in-private browsing window using the latest Edge version on Windows 10
- Try the update process again.
If you still have the issue, please let me know.
Thank you.
