Hello. This has probably already been addressed countless times, but if anyone can offer it, I just need clarification... I've been resident in the UK since 2005 (I'm a US citizen, husband is a UK citizen, having never lived or worked in the US). I hadn't worked since 2005 in either country (and have therefore not filed US taxes) until last year (2009), where I did some work in the UK. It is my understanding that I earned enough to warrant filing (3900 pounds sterling (before taxes)/ 6123 USD). I also understand that I should file as "married filing separately". Am I right in thinking that I need to file a regular 1040, as well as a 2555 EZ (to get the 2-month extension)? My situation is straightforward (no kids, no school, etc.)- I don't have any other taxable income and, although I have two bank accounts (one in the US, the other in the UK), both are checking accounts only, and have never held more than my income, plus a few hundred dollars, at any given time. So, do I just need to file those two forms or is there anything else I should complete? Also, this might seem obvious to some, but what is the difference between a "regular" form, and an "EZ" form? Thanks!!
