Avoiding double taxation when only income us US SS and UK interest income

For the 2024 tax year, my only income to report to the IRS is my SS payments and interest income from UK accounts (part of which I've already paid tax on to HMRC). 

The interest received is half of the standard deduction, so from what I can see so far, no tax due.

I also report all of my financial information using FBAR.

However, I'm looking ahead to the time when I will start to withdraw funds from my SIPP.  It may not happen for another year or two, but am trying to figure out how to report this.  I obviously can no longer use Form 2555 since I only have passive income, not earned income.

I haven't looked very hard (yet), but I'm wondering if there is some other form I would need to fill out to avoid paying tax on that which I've already paid UK tax...

I hope that makes sense, and look forward to any thoughts.  Thanks!

Assuming you are a UK resident US citizen, under current law US social security is completely exempt from US tax.

Yes, I am a US citizen, resident in the UK for 20 years.  I am more concerned about UK interest income and any withdrawals from my SIPP, as I am not taking my US Soc Sec into account for my form 1040 (other than entering it on line 6a).

Thanks!

This irs page should help in deciding whether or not you should file.

As pointed out above your taxable SS income is zero.

FWIW my wife (USC) took a full disbursement of her UK SIPP in 2023 and our preparers completed a Schedule E (K-1 input) which fed into Schedule 1 Line 10 and 1040 Line 8. Note: rightly or wrongly (there's some debate!) our preparers treated her UK SIPP as a Foreign Trust and so 3520 and 3520A forms were filed each year.

Thanks Tim - I think what you have posted is correct, based on some further research I've done.  This is really useful, and I thank you. 

It's not something I need to take care of this tax year, but really important for when I start taking distributions.

Thanks again!
