Hi,
I am in a similar situation trying to start my tax return today and also a bit confused on this as I started making payments to a pension through my employer during 2014 as well.
What I have interpreted from doing a bit of research, which I hope is correct, is that the payments made in to the pension from myself or my employer, and any gains on its value will not have to be reported on my 1040 tax returns this year, and would only start to make an effect on my 1040 forms when I start to draw payments out from it and it becomes income. That would therefor only make it an issue for a few decades down the road, I hope. But I would not take my word for it so would also appreciate if someone could confirm this is correct.
Assuming that was correct the other confusing point regarding the pension I encountered was whether to report my total income on line 7 of my 1040 as my total gross salary for the year, or only my "taxable income" which does not include the payments I made into the pension since they are done pre-tax. In the end I decided to use my gross salary, as I will be deducting the entire amount on a 2555EZ anyway regardless of which I chose, but not sure if that is the correct way to do it.
However I'm also not sure if the account value of the pension will have to be reported on a FBAR if I meet the filing threshold, which I haven't determined yet. I assume that it would need to be reported, but I didn't file one last year so have not yet looked into it.
