Ok, call me paranoid, but I am just double-checking this again. (Which would make it quadruple checking?

) Someone was kind enough to answer this question for me last year, and I cannot find the thread again.
I plan to retire soon and move to the UK. (I am a US citizen with dual EU citizenship, so it's doable.) I will have social security and a pension from the State of California (University of Cal). I have one 403B IRA, with about $30,000 in it that I plan to not touch for the time being - hopefully I can leave it there until I have to start taking minimum required deductions, which I'll deal with a few years down the road.
The U of C retirement people ~absolutely~ won't pay my pension directly to me in the UK -only to a US bank account. SSA will electronically deposit my SS to a UK bank.
I can deal with that - I'll use my Capital One credit card for most purchases and keep a US bank account to move money from. I'll use my SS for rent, etc., there in the UK. (Until I sort out a better system.)
I am aware that only the UK will tax my SS. I've checked the personal exemption and it looks like I won't be paying much tax on SS because it will be right around the personal exemption amount.
It is my understanding, and this is what I want to quadruple-check, that my U of C pension will only be taxed in the USA. Correct? Because it is a government pension and the tax treaty (I believe) says that payments funded by political entities, such as the State of Cal, are taxable only in the paying country?
I know about severing ties with Calif for residency purposes, so I won't be paying Cal State Income Tax (except partial year for the first year).
If I was a rich woman I wouldn't worry so much, but, while I'm not poor I will be of modest means and want to structure things so as to make the most of what funds I can control. The SS and the U of C pension will come up to just about, combined, what I bring home now after all the various deductions for insurance and pensions, etc., etc. are taken out. Enough for one person to live on decently, that. Finally.

Anyway, I know about the different tax years. I'm planning to arrive in May, so I'll basically run through one UK tax year and get an extension on my USA taxes until after I've paid anything I owe to the UK for that first UK tax year.
The current burning question is: will I owe anything to the UK on my U.C. pension?
Thanks again...
