How will state tax be calculated if I changed to a remote job in another state.
I'm trying to figure out the state tax consequences for income and capital gains because of working remotely for a NY company. I am currently a Massachusetts resident and will continue to live in MA. However, I am getting a new job in May and will work for a New York company remotely.
1. Am I correct to assume that I will be filing for ~5 months of income for MA and 7 months of income for NY (Not NYC)? Or do I file 100% of my income to NY and nothing in MA?
2. Am I correct to assume that if I realize capital gains before May, it will be reported on the MA return and uses the MA capital gains rate? Otherwise, it uses the NY rate? Or do I file 100% of my realized capital gains under the NY state tax, regardless of when they were realized?
My only type of income is employment salary and my only type of capital gain is from stock trades.
