Am i an Expat?

how does the IRS define one to be an expat? I have NOT renounced citizenship, but i simply reside/lived outside the US for more than 330 days of the year. When i file, I still use a US address though.

  1. Does this mean i get an automatic extension or do i need to fill out paperwork to receive the expat status?
  2. I’m almost finishes completing TTax online.  If I file an extension, will it reset and make me do it over again?
  3. I see there is a easy-extension.turbotax website.  shall I use this or just go through my normal TTax account.
  4. Is TTax going to charge me for filing the extension?  I might not need to file since I have no income in the US.  In that case, is there a way to do this at no cost on the gov. site?
