This resource takes you through the forms you need to complete when working for, and receiving payment from, a US based commissioner if you are not a US tax payer.
You will need to complete the paperwork in order to receive your full payment, without US tax being deducted.
All countries have their own forms and processes, which you can read about in the AOI resource here.
This resource is advisory only. It has been developed with kind support of Jonathan and Anthony Allman at Debut Art.
