My permanent home has been in CT as I was living with my parents and I have all my accounts/docs for there (W-2, license, etc). During the pandemic, I worked remotely from there as well. Recently, I am back in the office and thus rent an apartment in New York City to physically live and work during the week to make commuting easier. I make my income in NYC. My employer has the CT address on the W-2 and in their system. I will probably reside more than 180 days in NY. Does that technically make me a resident of NY and not CT? Should I change my address with my employer so that even my paychecks change to NY address or does that not matter - how does that affect withheld taxes? NYC has a city tax, when I file my taxes, do I put my New York apartment as my permanent address for taxes since technically that is where my income comes from? If I do not make my income in CT will I be taxed there? What about capital gains? Where are those taxed, the state you make most of your income or the state that you have as your address on brokerage accounts when those were set up?
Want to be prepared when I file for next year.
