Us backup holding

hey guys… i have a doubt.
i’m from portugal and i would like to know why my sold itens from russia, finland or brazil keep getting tax with US backup witholding tax?
isn’t this tax holding for itens sold out to US costumers?


Sort of. You need to fill out the W8 to certify that you’re not a US author, so you don’t get it withheld on all sales. If you fill out the W8 then you’ll only have tax withheld on US sales, and that can be reduced if you fill in your foreign tax ID number.
