Please forgive me if I'm confusing things. Also, please forgive me if it seemed like I was slagging off any tax professionals on this forum. I've gotten some terrific advice on this forum (in particular doing 1116 rather than 2555 to get additional child tax credit..).
As I understand the previous posts, anytime I use the provisions of the tax treaty, I should also attach an 8833. I was thinking then that I should now send it off with an amended return (ugh..) to explain that, in accordance with the tax treaty, I didn't include contributions I and my employer made to the pension scheme on line 7 1040. But then I read the instructions for form 8833 and find that you do not have to include an 8833 with your tax return if...
"You claim a treaty exemption that reduces or modifies the taxation of income from dependent personal services, pensions, annuities, social security and other public pensions, or income of artists, athletes, students, trainees, or teachers. This includes taxable scholarship and fellowship grants"
Here, "income from dependent personal services" mean wages as an employee (why can't they just say that??). So, do you think I still should file and amended return with an 8833? Am I really misreading the tax code?
The advice given in earlier posts suggest that I should recalculate my income without using the treaty provisions because it would allow me to deduct my pension contributions from my pension when I collect it in 20 years as calculated using the "general rule" for non-qualified pensions. This seems like a great idea provided it doesn't push me into the AMT. However, what is the point of including the employer contribution? Surely, that will not be part of the cost-basis I could claim under the simple or general rules otherwise I would have a huge windfall and almost none of my pension would be taxable under the general rule. (Actually, for foreign pensions prior to 1963, you could claim the employer contributions as part of the cost basis! I guess expats in the old days made out like bandits..).
There are thousands of Americans in the UK using the same pension scheme as mine and I bet hardly any of them think they need to include the employer pension contribution (14% of gross salary) in their non-exclusionable (non 2555) income on 1040. I have no idea what they do with their employee contributions (6%) ..
So my tentative conclusion would be that (1) the tax treaty allows you to not include employer contributions and you don't need to file 8833 just for doing that but (2) you should include employee contributions to the pension plan as you can use them for your future cost-basis on your pension distribution. On the other hand, (2) seems to give us a blatant loophole since we get a tax deduction on contributions that avoided tax by the UK (via tax relief) and US (via tax credit) in the first place. (We get the contributory benefits of a qualified plan but the distribution benefits of a non-qualified plan). It almost seems like article 15 of the tax treaty is just a way to trick us out of doing this.. Actually, when I read the tax treaty, it seems to actually require that you exclude both employers and employee's contributions. Is the tax treaty just an option? That doesn't seem reasonable.
I would sure like the opinion of a grown-up on this. Is the IRS person at the US embassy very helpful? What would a UK/US taxconsultant charge for advice? Thanks for your help!
