If you live in CA and want to register a vehicle in AZ, we have no problem with it.
However, California would have a big problem if you EVER bring that vehicle into California. CA laws require their residents to register any vehicles owned by them in CA. Unless the vehicle NEVER enters California. Not passing through. Not bringing it in for repairs. Not a day trip to Needles or Big River. NEVER!
It's a Criminal Offense (Misdemeanor) to do so, and fines are hefty, along with DMV fees, penalties, interest, towing and impound fees, and a host of other problems. Trying to save a few bucks on annual registration could cost over $2,500 to clear up. Jail time (although unlikely) can be imposed.
If you have a California Driver's License. Work in CA. Reside in CA, and have AZ plates on your vehicle you would be a target. CHP and local cops are always on the watch for out-of-state plates in CA neighborhoods and business parking lots.
We've been going out to my elderly Mother-in-law's place in Hemet a lot lately. I've been stopped a couple of times by CHP and Hemet PD to check my residency.
this is very true.. i never even got pulled over, just got a letter in the mail telling me that i am guilty of fraud and had like 15 days to get the vehicle registered in california. was told by the CHP that most are turned in by relatives or neighbors. good luck.
