Individual (Taiwan) cannot complete tax profile: "Tax ID type" only accepts 8-digit business Uniform Number

Question

Individual (Taiwan) cannot complete tax profile: "Tax ID type" only accepts 8-digit business Uniform Number

Brian Huang 10

Account type: Individual. Program: Microsoft Store (Taiwan).

When creating the tax profile, at step 3 "Tax Residence Country/Region", the field "Tax ID type" is required ("This is a required field."). The only option is "Uniform numbers", and it only accepts an 8-digit number, which is the Taiwan business registration number format.

I am an individual, not a business, so I do not have an 8-digit Uniform Number. My Taiwan taxpayer ID is my 10-character National ID number (1 letter + 9 digits), which the field does not accept. The same happens in Chrome and in Edge InPrivate.

I also tried to open a Partner Center support request, but submitting it fails with "There was a problem creating your service request. Please wait 10 minutes and try again."

How should an individual resident of Taiwan complete this step?

Update: I have tried to open a Partner Center support request several times over three days (different categories, Chrome and Edge InPrivate), and it always fails with "There was a problem creating your service request. Please wait 10 minutes and try again." My support request list is still empty. Could someone from the Partner Center team help, or tell me another way to contact the tax profile team?

I am also affected by the same issue. I have an Individual Microsoft Store developer account in Taiwan, and the Tax ID type only offers “Uniform numbers.”

Thank you for confirming. It helps show this is a form issue, not an account-specific one. If you can, please also click "I have the same question" and contact Microsoft support. More reports may help this get fixed. I will post here if I get an answer.
