“I lived and worked in South Korea for 2 years. Last year, I claimed the Foreign Earned Income Tax Exclusion but I'm unable to do that again for this year as I was only a resident for 7 months. “----> To qualify foreign earned income exclusion, you must either reside in S.Korea for the entire year, 365 days, or be physically present in S.korea for 330 full days during a 12 month period. When you qualify for the exclusion, but resides in S.Korea only part of theyear, your exclusion should be prorated.For example, if you reside in S.korea for the last 210 days of 2009 and the first 300 days of 2010, then you meet the 330 days in a 12 month period requirement. Thus you qualify forth exclusion in each year. However, assuming the max. exclusion in both years is $91,400($91,500 in 2011, I guess), the max. exclusion must be prorated in both years as follows; 2009; 210/365*$91,400=$52,586, 2010; 300/365*$91,400=$75,123.
“How do I file this year with partial foreign earned income, no US income, and no W-2s?”--->As a US citizen or a US resident alien under either US Tax Code or US INS Rules, you are liable for taxes(both federal and state or local taxes(if applicable) on your US source and world wide income.
