working for a US firm in the UK

Hello,
I'm moving to Sheffield this summer for my wife to start her PhD.  My current employer has agreed to allow me to telecommute for the 3 years we are there.  I believe the HSMP work permit will allow this.  

But since I will be paid by a US firm there are some complicated tax issues. I think I will have my paychecks direct deposited into a UK bank account.  I'll be personally responsible for UK taxes.  My company will be withholding 401K contributionsl health insurance, and FICA.  I understand that I can get tax credits from the US for taxes paid to the UK.

My question is for the UK side of things.  What do I report, how do I report it, and to whom to I report it?  

I assume your company does not operate any payroll in the UK and tha you are the only employee in the UK? If this is the case, you need to make your monthly payment to the Inland Revenue yourself, by calculating your own tax liability fo the year and pay 1/12 of it to the IR every month. You need also to have a certificate of coverage in order to be exempt from UK social security payment. Have you done this?

It might be quicker to have a chat about all the issues you might face and the forms you need to file before / when you get here. Feel free to give me a call on +44 208 466 9297.
