How is it paid?

Sorry still confused and have another kinda related q.  I am trying to decide to take, if offered, a job with a big UK company.  I would be a full UK company employee so I guess they'd take care of tax withholding etc.  I understand, apparently, that I will pay normal and customary taxes on my UK income in pounds.  Then I will be expected to pay US tax on everything I make over the exchange rate equivalent of $80K.  But, I do understand from a lawyer millionaire friend of mine that I can write off all my UK taxes paid on my US  return and he suggests that I would end up paying very little US taxes, then, if any.  Does that sound about right?  I intend to stay at least 3 years, maybe forever.

Second q:  I am very concerned about salary equivalencies.  It seems like rents/property valuesare about the same in the areas I might live (suburban London and Edinburgh-though Edinburgh a little cheaper) as I am experiencing here in Washington, DC.  But it appears cars are WAY more expensive as are some other things. Therefore, any advice on, if I make $107K here, what I should use as a guide over there in pounds?  They have talked 90K pounds but I am not sure that is enough given higher costs.

Thanks
John

No, not all of your UK taxes can be deducted from your US taxes.

There is an interesting thread going on over in the US/UK Taxes sub forum here to take a look at on that very subject.  You need to read and understand IRS Form 1116 and instructions to figure out what might be deductable and what might not as well as you have to address tax treaty issues between the US and UK to minimize your total tax burden, but it will almost always be more if you income would be over $80,000 per year.  That is why tax equalization packages are common benefits for expat employees.

Unless your millionaire lawyer friend is a US/UK tax lawyer, then I would be very careful in heeding that advice.  Just take a look at the US/UK Tax forum here and you will see that answers are seldom trivial.
