I only know some of these answers
1. What forms do I need in order to complete my taxes? I don't believe we receive a W2 form here so what documents do I need from my current employer in order to get started?
Nothing particular- just need to be able to add up 1 years worth of pay and then convert to US dollars. You can find an exchange rate on the IRS website
2. Once I have the correct forms from my employer what form(s) should I use to file and where can I find them?
You file on form 2555EZ or form 2555- You can get these forms off the IRS website. however ,if you're over the income threshold $91,000 or about there, you'll need to do other things with tax credits, housing exclusion, etc. Which starts to go into a territory I know nothing about!
5. When is the deadline for expats to file?
You get an automatic extension until June 15 and then can get an extension up until October 15th to file.
There's some good information here:
