We already collect tax residency. Why are you asking for it?
If you use Verify, we do indeed ask for tax residency, however this used to be a single input field only. We now need to know all tax residencies for a customer. We expect the majority of customers to be tax residents of a single country (UK), but if a customer is a tax resident in multiple countries, we'll need you to let us know.
You can see how to submit tax residencies via API in our API reference linked here.
