A response to a Freedom of Information request made by Gherson shows that "non-doms" paid £6.4bn in income tax in 2012-13, the latest year for which figures are available. HMRC also seem to have reduced the figure that they previously said was paid by non-doms in 2011-12 from £6.8bn (see Pinsent Masons press release of 28 April 2014 http://www.pinsentmasons.com/en/media/press-releases/2014/income-tax-pai... ) to £6.35bn. The latest figures show a relatively steady incremental increase annually in the amount of income tax paid by non-doms, having risen from £6.26bn in 2010-11 to £6.35bn in 2011-12, then to £6.40bn in 2012-13.
The latest figures also show a bounce-back in the actual number of non-doms to 115,300 following a drop to 112,700 in 2011-12 from the previous year's 115,100. This represents the first increase in the number of non-doms for many years.
These figures show that non-doms continue to make a substantial and increasing contribution to the UK economy, despite their very negative portrayal in the run-up to last month's General Election.
