I am a EU citizen living in the UK. I need to invoice an US client via pay pal, during 6 months. Do I need to include VAT in my invoice? What are my legal obligations in the UK towards taxes and NI as a freelancer? Thank you
You should start here:
If your income as a freelancer does not exceed the threshold of £82,000 a year you don't need to worry about VAT at all. You usually only charge VAT within the EU and you must register first.
