I live in NJ but my company is based in NY. 4 days a week I work remotely from my home in NJ, while 1 day a week I go into the office in NYC.
I know I need to file NJ state tax form for the 4 days a week I work from home but how do I make sure I'm not double taxed in NY, since I only work 1 day a week there? Am I supposed to be double taxed on all my income? If not, how do I specify I should only be taxed for 52 days of work in NY?
Originally my employer didn't even have me withholding ANY money for NY but it's my understanding I do have to file NY taxes.
After talking to HR (who seems to have no understanding of what I need to file) they have me filling out a W-4, an NJ W-4, and a IT-2104 (NY.) Does this sound right?
