No but you do get charged a US withholding tax on all dividend payments (15% - 30% without a W8-BEN form but Freetrade do that for you). The charge is unavoidable.
When buying and selling shares etc. there are all sorts of little regulatory fees etc. but those are built into the purchase experience.
Freetrade converts to pounds so you pay 0.45% FX fee, but then if it’s in your ISA, it’s tax free (except FX when you sell). Like hrochfor1 said, you’ll complete the form which takes care of everything.
Thanks so much Adam! Am I right in thinking then that freetrade deduct any taxes at point of payment? No US tax return forms after need to be completed? Thanks
