Firstly, sorry if confusing.
I recently moved to NC(for my daughters schooling) after living in the UK for 5 years, my husband remains in the UK, working for a UK company, income in pounds paying UK taxes but supporting the family in the US. No US income so files but does not pay (or very little US tax). We rent so no property tax, etc. Now I would like to get a teaching job in NC. My husband is in the highest tax bracket. How would my income be taxed? Would it cost us more than its worth? My husbands opinion is it is definitely not worth it and in the end will cost us money. What about filing separately, would that help? Any answers would be helpful, thank you.
