@DMarkM1 - I have a similar situation. I lived in NYC part year and based out of NY office, then moved to NJ and work office in NJ. I primarily WFH and employer has offices in both NY and NJ. Since the NJ move it seems that employer appropriately changed the state tax withholdings and only NJ taxes once the switch was made (from what I can tell looking at the paystub).
For sake of example here are some sample numbers for discussion:
NY - lived and worked Jan to Aug 2023. Income - 60k, w2 shows 100k
NJ - lived and worked Sept to Dec 2023. Income - 40k, w2 shows 40k
A few questions:
1. How do I know if I am double taxed and need to claim credit on the part yr resident form?
2. If I need to claim tax credit paid to another state do I claim that on my NJ form for any NY taxes paid or do that on the NY form?
