2014 was the first year that I contributed to a UK employer pension. This means I need to consider how to treat it for US tax purposes. I've also got a bundle of unused FTCs carried over from prior years that I need to start thinking about using before they expire.
The strategy that gives the best result for me is to elect Treaty protection for gains (Article 18(1)) but not for contributions (Article 18(5)). My excess FTCs are used to pay the notional US tax due on the money that my employer and I contributed to the pension, thereby building up a US tax free basis for future use. The IRS is also prevented from looking at the PFICs within the pension.
Because there is a lot of disagreement on the subject of UK pensions and the IRS has not provided much guidance, I was thinking to file a Form 8833 disclosing the existence of the pension and stating clearly which provisions I am electing to use and not use. The IRS can then decide whether they disagree with the position I've taken. My response if they did disagree would be to file an amended return electing into Article 18(5) as well. If I had to do this, my tax wouldn't change, but would there be any penalty due? I assume I'd be no worse off than if I'd filed that way to begin with, but am I missing anything?
When a taxpayer files with a treaty-based position, does the IRS have the usual 3 years to raise any objections, or is there anything that would cause the statute of limitations to remain open longer?
In general, is it permissible to elect into some Treaty provisions but not others, or do you have to go whole hog?
I will also be disclosing the pension on my FBAR, but do not need to file Form 8965 (I'm under the threshold).
Thanks for any feedback.
