I’m a UK citizen and resident, and a former US citizen. I receive a small US social security benefit under the US/UK totalisation treaty. It’s taxed by HMRC, as per DTT Article 17.3. Yet apparently, if I understand correctly, if I lived in the US, it would be tax-free
So - recent discussion of treaty provisions for the taxation of social security pensions has got me wondering whether I might have a claim for exemption from UK tax under paragraph 1(b) of Article 17:
1. (a) Pensions and other similar remuneration beneficially owned by a resident of a Contracting State shall be taxable only in that State.
(b)Notwithstanding sub-paragraph a) of this paragraph, the amount of any such pension or remuneration paid from a pension scheme established in the other Contracting State [the US] that would be exempt from taxation in that other State [the US] if the beneficial owner were a resident thereof shall be exempt from taxation in the first- mentioned State [the UK].
I would be interested to hear if any former USC has enquired of HMRC about this possibility.
(Not significant for me, with only a small US SS pension, but could be significant for former USCs with larger US SS entitlements.)
