what state would I pay Income Tax to?

Although the laws vary from state to state, generally if you move to another state, begin working, and have no intention of returning to your original state, you are immediately considered a resident of the new state for state income tax purposes. So, in your example, when you take your new job in State B you immediately begin owing State B's income tax on those earnings and you owe nothing to State A on those earnings. When you file your year-end tax returns you will file as a part-year resident of both State A and State B.

If your move to State B is only temporary and you maintain your residency in State A, then generally both State A and State B will tax the income you earned in State B, though State A will likely have a credit for taxes paid to another state.

You pay state tax to the state where you made it, or where you lived when you earned it.

A year to get state residency for something like in-state tuition has nothing to do with income tax.

You pay State A for the time you resided there, and State B for the time you resided there.

your tax home is where you work

if you have a short,temporary, less than a year assignment in a different state, you would file non resident or part time in that state and your normal state return where your main occupation was

no, to be declared a resident of Calif. if you remain here 10 days, get a job, open a bank account etc. you are a resident

Yes I paid all my taxes and I'm from the great state of Illinois the politicians pay to play state. I think all the politicians in the states and government should not take pay increases for year and help their states out. The people pay too much to them any way.
