The US and UK tax system are totally different.

Despite living in a different country, you find yourself in the complicated predicament of having to file both US and UK taxes. This is because the US is one of only two countries that still taxes its citizens despite their change in location. The US taxation system is citizenship-based, it doesn’t matter where you live. It’s also based around the calendar year.

The UK tax system is residency-based, and runs from April 6, to April 5.

There is a comprehensive tax treaty (Totalization Agreement) between the US and UK, and it helps prevent US citizens and Green Card holders from double-taxation. Most income streams are covered, but not all.
