I am based in the U.K. Thinking about starting as a sole trader and selling handmade products of suppliers based in Turkey, on online marketplaces such as Etsy and Amazon. The customer will be ordering from my Etsy, amazon or another e-commerce shop. I will be fulfilling the order with my supplier in Turkey. The suplier will be sending orders directly to the customers in the UK or possibly other countries too. i am wondering what my tax responsibilies will be, who will be billing the customer and who will be paying VAT and import tax. If any foreign tax was to be deducted will I be able to claim foreign tax credit relief even if I am not VAT registered?.
