I'm a US citizen and have been living in England since Oct 2013. My husband is English and has always work here (in England). I started working same month I moved, so for all 2014 I've been earning. My gross income for 2014 (converted to USD) is about $52,000. I don't know if my husband's income is relevant. I've been filing US taxes since 2009, as I started working in 2008 after graduating uni. Does anyone have some guidance on how to go forward? I need information regarding the filing process, as I was just used to doing them myself through turbotax in the US.
As far as your husbands income, it needn't be relevant. You may file MFS (married filing separately). In this case, only joint accounts you hold with your husband will be of interest, and then, only on the informational forms (FinCEN 114 and 8938, if above the thresholds) but you do declare the interest from those accounts on your tax return (Schedule B).
If you have used TurboTax in the past and are comfortable with it, you can continue to use it now. It can handle most of the forms required for filing from abroad.
You've two decisions: do you file MFS or MFJ (married filing jointly) and do you use form 2555 or form 1116. Most use MFS as it keeps your husband out of US tax affairs. As for the forms, 2555 is the easiest, but 1116 can be more tax advantageous. Run the figures in TurboTax both ways to find if there is an advantage.
In your case, and assuming no additional sources of income, a 1040, Schedule B, 8965 (ACA exemption), and either 2555 or 1116 would be a good start. And don't forget FinCEN 144 and/or form 8938 if you meet the requirements for filing either.
If you were working in the US up to Sept. 2013, and in the UK during Oct., Nov., and Dec. of 2013, this years return should be easier than last years.
