Q. If I work in NC for 3 weeks remotely from my son's home this coming April, but live and work in IA with my employer in IA, do I owe NC income tax on that income and have to file an NC tax return?
A. Yes, but "nobody" does. See http://money.cnn.com/2013/06/28/pf/taxes/business-traveler-tax-threat/ If you live in a state without an income tax (e.g. FL or TX), it’s more likely you should file in the work states. You can't use the "it all comes out even" rationale for not filing.
