First, I’ll apologize for all the 1), 2)s, and 3)s here, but it’s probably the easiest way for me to do this. In this post, let’s concentrate on interest in 2008.
1) A general statement to start with. You do need all of your UK statements for Mar. 2008 to Dec. 2009, but try not to let the UK tax year vs. the US tax year complicate this. We’re doing this for good old Uncle Sam, so it is tax year equals 1 Jan. to 31 Dec.
2) So let’s start by concentrating on interest earned for 1 Jan. 2008 to 31 Dec. 2008. According to the info you show at the bottom of your posts, you arrived in the UK on 13 Mar. 2008. You need to review what interest you may have received from 1 Jan. 2008 to 13 Mar. 2008 on any US accounts, and if you left bank accounts (other than your 401K) any additional interest from 13 Mar. to 31 Dec. 2008.
3) Next, you need to calculate the gross interest earned in the UK from 13 Mar. to 31 Dec. 2008.
4) You then add item 2) and item 3) together. Technically, the IRS operates on a “rounding to whole numbers” principle. If the sum of 2) and 3) is less than 50 cents ($0.50), then you did not “technically” receive any interest in 2008. You therefore wouldn’t have been required to declare any interest on line 8a of the 2008 form 1040.
5) If it is over 50 cents, then you would be obligated to file a 1040X.
6) Thus far, I’ve carefully avoided Sch. B. If the interest is below 50 cents, then the only reason to file a 2008 Sch. B would be for information purposes only (Part III, the NO box on line 7a), in other words, to inform them that you did have a Foreign Bank Account, but that account had an aggregate value of less than $10,000, hence no FBAR required. It would not be required for Part I since you “technically” had no interest and no penalty would be due for the error of not reporting unearned income.
7) If the result in item 4) is over 50 cents, then you will be filing a Sch. B with your 1040X.
Two other things concern me:
You are worried about the correctness of how you prepared your 2008 return. If there had been a problem in how you prepared it, the IRS would have informed you by mail. Since you’ve moved twice, if a letter had been sent, it may not have found you. Please send the IRS the change of address form for your new address as soon as you are able. If you’re confident that your mail has been forwarded, and you haven’t received anything from the IRS, then that’s good news. Secondly, as Sara so rightly pointed out, be confident that you declared ALL of your income, including any benefits in either the US or UK. This of course includes anything in the 3 months you were still in the States in 2008. We can see from your info that you were granted ILR in 2010, so for 2008, you will already be certain of your situation. We don’t need any details, but just be confident of your situation for 2008.
All of the above exercises apply for 2009, so once you’ve sorted 2008, you can begin to assess 2009. You still have over a month before that is due. And again, as Sara mentioned, try to think of anyone (friend or family) that may be able to assist you with the returns, and keep looking for very affordable professional advice. Your info says you’re in Oxfordshire. There are many Americans in Oxford. Maybe someone there could check things for you.
I’ve just noticed your last edit. Let me post this and someone will get back on the edit.
