Work in office in NY and at Home in NJ... do I need to allocate wages for both states?
My wife and I live in NJ. I work in NY and 100% of my income is earned in NY.
My wife works 3 days/week in NY at her company's office and informally works from home in NJ the other 2 days/week. By informally I mean her boss allows her to work from home 2 days/week but her company is only withholding state taxes for NY and her clients are in NY.
Does she need to allocate her wages 60/40 between NY & NJ? If we allocate wages between the two states, does that flag us with NY state for potential underpayment? Does NJ get pissed that we under-withheld for the state? I'm a bit confused and want to make sure we're doing everything by the book/avoiding audit risk.
