How Alabama Vehicle Ad Valorem Tax Works

Alabama taxes motor vehicles as personal property each year. This "ad valorem" (Latin for "according to value") tax is separate from the one-time vehicle sales tax you pay when purchasing a vehicle — it is an ongoing annual charge collected at registration renewal time.

The Formula

Assessed Value = Market Value × Assessment Ratio
Personal passenger vehicles (Class IV): 15% assessment ratio
Commercial / other (Class II): 20% assessment ratio

Ad Valorem Tax = Assessed Value × Millage Rate ÷ 1,000
Example: $25,000 vehicle × 15% = $3,750 assessed value
$3,750 × 40 mills ÷ 1,000 = $150.00 ad valorem tax

Alabama Vehicle Classes

  • Class IV (15%): Private passenger vehicles owned and operated by individuals for personal use. The vast majority of cars, trucks, and SUVs fall here.
  • Class II (20%): Commercial and business vehicles, or any motor vehicle not qualifying as Class I or Class IV.
  • Class I (30%): Vehicles owned by public utilities. Not applicable to most private owners.

Market Value vs. Purchase Price

Alabama uses its own DoR-published value tables — not your actual purchase price — to determine taxable market value. These tables are based on vehicle make, model, year, and body style, and are similar to NADA wholesale values. Your tax may be lower or higher than your purchase price would suggest depending on the vehicle type and age.

When Your Registration Renews

Alabama assigns your renewal month based on the first letter of your last name:

Last Name InitialRenewal Month
A – BOctober
C – DNovember
E – FDecember
G – HJanuary
I – KFebruary
L – MMarch
N – OApril
P – RMay
SJune
T – VJuly
W – ZAugust

EV and Hybrid Surcharges

Alabama added annual surcharges on electric vehicles in 2020 (Act 2019-363) to offset the fuel tax revenue lost from drivers who don't buy gasoline:

  • Battery electric vehicles (BEV): +$200/year
  • Plug-in hybrid (PHEV): +$100/year
  • Standard (non-plug-in) hybrid: no surcharge

Exemptions

The following may qualify for ad valorem tax exemption on one vehicle:

  • Disabled veterans with a 100% service-connected disability rating
  • Former prisoners of war (POW)
  • Government-owned vehicles
  • Certain nonprofit organizations

Contact your county license office to apply for an exemption.

Frequently Asked Questions

Ad valorem is an annual property tax on motor vehicles. It equals your vehicle's market value × 15% (personal vehicles) × your county millage rate ÷ 1,000. It's collected each year when you renew your registration — separate from the one-time sales tax paid at purchase.
Formula: Assessed value = Market value × 15%. Ad valorem = Assessed value × Millage rate ÷ 1,000. Example: $25,000 car in a 40-mill county → $3,750 × 40 ÷ 1,000 = $150/year.
