Ok, being a cash-basis taxpayer (income "counts" when I receive it or spend it), I have the option to choose to deal with my foreign tax credits on a "paid" v "accrued" basis. Dealing only with form 1116 & FTC here:
Mismatch - How does the mis-match between tax years impact FTC? You get a bill from HMRC for taxes for April 2017 - April 2018. Your IRS taxes are for income Jan-Dec 2018.
Does the IRS not allow you to consider HMRC taxes paid for the portion of the HMRC tax year prior to January 1 2018 on your 2018 tax return?Paid - So, you get a tax bill from HMRC in 2018 for tax year 2017/18. If you don't pay the bill until 2019, you have to use the HRMC taxes towards 2019 IRS taxes. That is, you can only claim FTC in the year you pay the tax.
Is this correct?If the HMRC comes back at any point in a future year and adds taxes to your bill for the 2017/18 year, you cannot amend your IRS tax return to get credit for those taxes to 2017/18 if you have selected the "paid" basis. You have to add them to the tax year's return for the year in which you actually pay them.
Is this correct?Accrued - HMRC taxes formally accrued on 5 April 2018. If you select "accrued" on the 1116 Foreign Tax Credit form you attribute them to your 2018 IRS tax year when you file your IRS taxes in 2019, or soon thereafter. If you select accrued, you don't have to actually have paid the taxes in 2018 to be able to get credit for them for 2018 if you, for instance, have to file an amended return. If the HMRC comes back and levies more tax on that same year's income at a later date, you can still retroactively take that extra off your 2018 IRS taxes.
Is this correct?Paid vs Accrued (form 1116) - It would seem prudent to select "accrued" on section II of the form, as it would give you much more flexibility as to when you actually pay your tax to HMRC. There is a mis-match between tax years. If one has a simple income stream (say, retirement income), why would they ~not~ want to check "accrued" instead of "paid"?
Set-in-Stone? Once you choose "accrued" you always have to use "accrued". There is nothing that I see in the IRS regs that says if you chose "paid" you cannot then amend your return to "accrued". I did see one reference on a website that says that there's an IRS policy to not allow that. But it doesn't say that in the 1116 forms - just the "once accrued, always accrued".
Does the IRS allow you to change from "paid" to "accrued" on a 1040X? Retirement Income Resource Basketing - All retirement income (pension income, 401k/403b, IRA) from US sources that you want to have count as UK (foreign) income and that the DTA says should be taxed as UK income are put in the same "resourced by treaty" basket for the purposes of claiming Foreign Tax Credit. [That is, they might include "passive" income, but according to the DTA they should be considered primarily taxable in the UK, and so should be "resourced by treaty" and that box ticked on the form.]
Is this correct? Or, is it "foreign" income-tax, and not "foreign-income" tax? That is, if the UK taxes it, do you HAVE to "resource" it to be UK income to use a FTC? If you don't have to resource it as foreign to use FTC, why
would you want to select "resourced by treaty"?
Excess credit limits - If you pay more in HMRC taxes in 2018 than you owe to the IRS for 2018 for the specific basket income (let's say "resourced by treaty"), you can sometimes "carry back" some of that HMRC tax credit to the prior IRS tax year to apply to any IRS tax on the "resourced by treaty" income for that year that wasn't already negated by a foreign tax credit. Alternately, you can "carry it forward" and apply to future years' resourced by treaty IRS taxes. For up to 10 years.
Is this correct? If you have less income in year two (first full year after arrival), you may not have any excess credits to carry back, so you'll be double-taxed in the first year in that case. (Unless you can convince HMRC to give you credit for US tax paid.)
Hedging One's Bets - Let's say HMRC doesn't reach a final decision on what I owe until after 31 Dec. Can I pre-pay what I ~think~ my tax bill might be before 31 Dec so that I can still claim FTC on the finally decided amount? If so, and if I've over-estimated, will HMRC return that over-payment?
Eventually I'll write a "step-by-step" or do a flowchart of all this, I think. Once I truly understand it.
Simple answers
or yes/no, would be of much greater help to me than long, involved answers at this point. It's kinda like explaining nuclear explosions to a kindergartner. You just say that the atoms are pushed into each other and then there's a big explosion. You don't try to tell the kiddo about the finer points sub-atomic physics, quarks, etc.

Alternately, is there a taxes for dummies book that already addresses these questions?
