The expert that you requested is not online.
Unfortunately, you are taxed on your worldwide income in Oklahoma, regardless of where you actually performed services
I assumed the state income tax was calculated according to the laws of the state in which you were a resident when you earned the income (Texas) and since this severance agreement was for past services in Texas it would not be subject to Oklahoma income tax since it is not a pension.
Tax is calculated on the cash basis, based on when you are paid. If you are paid while you are a resident of a certain state, you will owe tax there for that income unfortunately
Thank you for the assistance.
is there anything else I can assist you with today?
