I live in a state (Oregon) with both federal and state W4s. None of my employees want any type of different state deduction. My question is, can I just setup their requested W4 allowances under the federal section or do I have to set it up in the state section also?
If I do have to set it up under federal and state, should I only set the federal to the requested allowances and leave the state at zero or should I make them both the same?
