Dual status foreign income 2010
I'm so confused and I hope somebody can help me here. I spoke to about 5 accountants and each one is saying something else.
I came to the US in September 2010 as a green card holder. I was here for two weeks and left back to Poland for the rest of the year. I was just working in Poland in 2010 and I was single. I did file my taxes in my home country. I did not file a tax return for 2010 in the US as I was advised by a CPA. I came back to the US in 2011 and started filing taxes since then.
I read on the IRS website that under Green Card test I should file dual status tax return on worldwide income because I became a resident in September. I had no income in the US. What forms should I file? Can I claim foreign earned income exclusion if dual status? There is a tax treaty agreement with Poland.
Thanks for any advise!
