Musing:
Now that I've got it straight in my head (with the benefit of much extremely helpful forum advice) exactly what I'm going to put on these 1040s (once I stop procrastinating and get down to it), I'm still puzzled by the seemingly contradictory language about not just one of my pensions but both of them.
UK State Pension: Article 17.3 is excepted from the Saving Clause but doesn't seem to cover UK State Pensions paid to a US citizen who is a UK resident. Yet the Treasury Technical Explanation couldn't be clearer:
Paragraph 3 [of Article 17] provides for exclusive residence-country taxation of social security benefits.
UK Local Authority pension: Article 19.2 makes this exempt from US tax for a US citizen who is also a UK resident, but Article 1.5 seems to except 19.2 from the Saving Clause only for those who are
not US citizens. Yet IRS Publication 901, "U.S Tax Treaties", says very clearly:
Pensions paid by, or funds created by, the United Kingdom, its political subdivisions, or local authorities for services performed for the United Kingdom are exempt from U.S. income tax unless the recipient is both a resident and citizen of the United States.
(my emphasis)
It strikes me that:
(a) both these income items are pensions; and
(b) both are pensions funded by UK public funds; and
(c) the troublesome language in the Treaty, in both cases, concerns cross-border payments.
With the UK State Pension, only cross-border payments seem to be exempt. With the UK LA Pension, only cross-border payments seem to be excepted from the Saving Clause. Yet the guidance, for both pensions, says non-cross-border payments (payments by the UK to a US citizen who is UK resident) are taxable only by the UK.
I'm led to theorize that the Treaty provisions and exceptions on pensions start from the assumption that pensions funded by each Government's own coffers are to be taxable only in the state that funds them unless otherwise stated. And that's why only cross-border payments are mentioned: they're the exception that proves the rule.
Perhaps.
