Regarding taxation of US Social Security for UK residents:
Article 17(3) of the DTA states:
"Notwithstanding the provisions of paragraph 1 of this Article, payments made by a Contracting State under the provisions of the social security or similar legislation of that State to a resident of the other Contracting State shall be taxable only in that other State"
I am confused by Durhamlad's post that a UK resident pays income tax on no more than 85% of US Social Security benefits because this is the maximum liability for US residents. I thought that HMRC could tax this income according to its own rules -- i.e. adding the total Social Security received to other income sources on a Self Assessment form. I have been reporting, and paying tax, on the total so would appreciate a DTA reference to show I need only report 85%
(Before 6 Apri; 2017, only 90% of foreign pensions were taxed, but that was a different issue)
