Yes, as long as your itemized deductions exceed your standard. Again though, it's only a 20-25% tax savings off a relatively small amount the old way.Some good points have been made on the used car market, and I can see how it sucks for that. I buy new cars and drive them for over 10 years. When I first learned about the TAVT, I honestly didn't believe it. If you buy new, they basically swapped sales tax for the TAVT and you're done. I actually bought a new car in 2012 before TAVT was in effect, and I had the option to "opt-in" to the TAVT. I went to the tag office with my dealer paperwork. Since my sales tax amount was the same or more than the TAVT was, I didn't have to pay anything else and now I'm on the TAVT system and NEVER have to pay ad-valorem. Compare that to the ad-valorem I still have to pay on my 2001 vehicle.
One difference is you can't deduct TAVT from your taxes. You used to be able to deduct the sales tax and ad-valorem. You still come out paying far less in TAVT for a new car purchase.
