Printful may request W-9 forms from our affiliates and contractors. These forms don't get sent to the IRS; Printful uses them to collect information about our customers (name, business name, type of business, address, taxpayer IDs, etc.) and for 1099 forms. Affiliates can read more about taxes here.
Filling a W-9 form is pretty straightforward. If you're a sole proprietor, provide your name and Social Security number. If you are operating as a business, you should indicate business name and employer identification number (EIN).
