I'm 26 and have lived outside the U.S. all my life. I never filed a U.S. income tax return. I know nothing about doing my taxes, and would like to file for the years that I neglected to before the penalties become more serious. Here are some questions I have:
What exactly are the penalties, if any, for not declaring my income in the past 6 years?
How do I file for all the years that I didn't?
Can I do this myself or should I get a professional to help out?
