How each state structures it
Arizona
Arizona's vehicle registration cost is dominated by the Vehicle License Tax (VLT) — an annual depreciated-value tax that replaces the personal property tax other states charge on vehicles. Year 1 VLT on a $35,000 vehicle is about $588 (60% of MSRP × 2.80% = $588), with the assessed value decreasing 16.25% per year thereafter. Beyond VLT, Arizona is one of the cheapest registration states: $8 registration, $4 title, $1.50 air quality fee, $5 plates. The sales tax — technically Transaction Privilege Tax (TPT) — is 5.6% state plus city and county additions that vary 0-5.6%, putting Phoenix and Tucson around 8.6-8.7% combined. Arizona is also one of about 9 states with no EV surcharge, and uniquely, private-party vehicle sales pay zero TPT — a substantial tax savings for buyers willing to skip dealer financing. A new $35,000 vehicle in Phoenix runs about $3,600 first-year (mostly VLT and TPT), dropping to about $610 in year 2 as VLT depreciation kicks in.
Washington
Washington's vehicle registration cost depends overwhelmingly on whether you live inside or outside the Sound Transit Regional Transit Authority (RTA) district — a service area covering most of King County (Seattle), parts of Pierce County (Tacoma), and parts of Snohomish County (Everett). Inside the RTA zone, the 1.1% MVET on depreciated MSRP can add $300-$700 per year. Outside the zone, registration is modest — about $89 annually for a typical passenger vehicle ($43 base + $25 weight + $21 filing/service). Washington also charges $150/year for battery EVs and $75/year for hybrids and plug-in hybrids. Sales tax ranges from 7% in rural counties to 10.25% in Seattle. A $35,000 new vehicle in Seattle (RTA + Seattle sales tax) runs about $4,200 first-year; the same vehicle in Spokane runs about $3,300.
What this means for you
- Buying a new car: Arizona is roughly $23 cheaper than Washington in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Washington is cheaper to renew annually by about $47/year. Over a 5-year ownership period that's roughly $235 in renewal-fee savings alone.
- If you drive an EV: Arizona has no EV surcharge while Washington adds $225/year — a meaningful long-term cost advantage for Arizona EV owners.
- Structural differences: Neither state imposes an annual ad valorem vehicle property tax, so renewal costs stay relatively flat after the first year for both.
