You will file a part year return for NJ and SC reporting the amounts earned in while living in those states. Since you work remotely, chances are you don't owe NY but you might be that one that should. Review the source income rules and determine if you are required to file.
Since NY taxes were withheld, you will file as a nonresident and claim either:
- no taxable income and get a full refund
- claim the income, pay tax and then get a credit on each part year return for the matching portion that is double taxed.
You must file NY Form IT-203 if you meet any of the following conditions:
- You have income from a New York State source (see Nonresidents: New York source income) and your New York adjusted gross income (Federal amount column) is more than your New York State standard deduction. Complete Form IT-203, lines 1 through 31 and compare the line 31 Federal amount to your standard deduction from the New York State standard deduction table.
- You want to claim a refund of any New York State, New York City, or Yonkers income taxes withheld from your pay or from your unemployment insurance benefit payments.
- You want to claim any of the New York State, New York City, or Yonkers refundable or carryover credits.
