Foreign Earned Income Exclusion - Service vs. Product?
As the name says, its for income earned in a Foreign country. If you have been paying US income tax on this while living in the US, nothing is going to change here. You should be informing yourself on how to avoid double taxation in your new country of residence. Passive income earned abroad (dividends, interest) also do not fall under this exemption.  The purpose of the Foreign Earned Income Exclusion is to make it easy for expats who work abroad to avoid double income taxation without going through the complicated process of applying for tax credits. The US is the only industrial country that taxes its residents regardless of where they reside. That is also why it only goes to about $100,000 a year. If you are a high earner, they want to make it more difficult. Also as a side note, since you are going to be abroad for a year. I will point out that if you have more than $10,000 in foreign accounts at any point in the year you need to declare this in an FBAR form. This is not advertised as well as it should be and carries ridiculous penalties for non-compliance. I can't count the number of times I have heard a US expat say that they were unaware of this.
