US independent contractor invoices UK firm

Hello,
I am a US independent contractor and I will be doing a 1 month research project for a UK based company. I will performing all of the work in the USA. I plan on invoicing the UK company a gross amount. I will pay taxes in USA for this. Does the UK company need to hold back V.A.T? Also, does it matter whether I invoice them in GPB or USD?

Thanks for your help!!!!

You are not VAT registered. If you were, YOU would invoice with VAT included, and YOU would be responsible for filing a VAT return and paying VAT.

I would invoice n US$ and ask that you be paid in US$ - a bank transfer (among other options) can be initiated in the UK to pay a specified amount in your currency of choice. That avoids any Fx calculations when you file your US return.

I can confirm what earlier post had to say, plus watch your bank statement when you are paid. I work with US contractors and am given the option of charging either our UK company, or the contractor, for the US$25 wire charge. If your account is charged for it, write it off as an expense.
