Following up on my last post regarding how taxes work in the UK—as a general guide to assist you when you move to London—today I’ll speak to UK income tax rates in particular.

To start, anyone earning an annual salary under £100,000 is tax exempt for their first £6,475 earned.  This is called your “Personal Allowance,” and for those earning above £100,000, this allowance will be reduced £1 for every £2 you earn above £100,000.

Senior citizens aged 65-74 years and earning less than £100,000 per year will receive a higher personal allowance of £9,490.  For age 75 and over, the personal allowance is £9,640.  However, no age category is exempt from the limitation imposed on salaries above £100,000, discussed above.

With regard to your income tax rate as of the 2010-11 tax year:

– the basic rate applied to annual income up to £37,400 is 20%

– the higher rate applied to annual income from £37,401-£150,000 is 40%

– the additional rate applied to annual income above £150,000 is 50%

Recall from my earlier post on American expats having to pay US taxes that, if you’re moving to London from America, you will receive a refund for the difference between a higher UK tax rate.  Canadians moving to England likewise enjoy a tax treaty with the UK that protects them from a double taxation.  It’s my understanding that only U.S. and Liberian citizens still pay taxes to their nation of origin while living in the UK from a different country (please do correct me if I’m wrong! It happens :)), but do consult your respective government’s revenue agency for their policies regarding taxation abroad to be certain.
