Yep, basically this. I had naively assumed a drivers license and address change (along with utility bill) would suffice. I was exceedingly wrong. My situation was I moved out of my home state for about 3 years, and moved back. About a year (or two? been a bit) after I was back the past-due bill came. I will also say that due to those actions I made it a life plan to leave this state permanently as soon as my kid is in college. I will not give another dime to them willingly if I can help it. Edit: And just in case this is helpful to someone. I was "double taxed" by both states, but since these states had an agreement between them I was able to deduct the state taxes of the first state, and simply pay the difference. The difference wasn't extremely substantial, but 3 years of taxes plus 5 years of penalties/interest gets rather absurd quickly - where those fees end up being well over half of the total bill due.
