When my daughter first moved to Germany after college, she worked for a university teaching English to foreign students. She did make over $10,000. She works from time to time teaching English but makes a lot less than $10,000. Her German husband is a banker making over $190,000 and they have a joint bank account. From what I get from her, that is where FBAR comes in, wanting to tax them on his income and her not reporting it. Can they do that or could she be mistaken and they are taxing her on her past income years ago teaching at the German university? Thank you, she is quite upset over this.
