Hello,
I have been employed in PA for the entire year. In June, I moved to Delaware.
My understanding is that I will file a PA40 and a De 200-01. I expect to owe incremental tax in Delaware above my Pennsylvania rate, with 100% of the PA state withholding as a credit on the Delaware return.
What is the official determination of when residency switched over? Is it self reported based on first day actually sleeping there, or based on something like the effective date of handing in PA license for a Delaware license?
Also, for Delaware, will I owe the incremental tax only on the amount of income earned AFTER the move? How would this be determined if I moved in the middle of a pay period? My income is not static for the entire year, and I'm not sure if I am supposed to be tracing actual paystub earnings in each state based on the effective date of the move, or rather just taking a daycount proration of the total income for the year and allocating between the states that way.
Thank you
