Car tags are expensive in Mississippi and Tippah County leads with the highest taxes in North Mississippi. The median household income in Tippah County is $51,141/year compared to $82,980 in Desoto County. But citizens of Tippah County pay almost 25% more for a car tag.
Your car tag cost is mostly driven by your county’s total millage. Same vehicle, same MSRP, same model year → higher millage = higher tag. Mississippi calculates the tax (ad valorem) on a car as 30% of MSRP (then reduced each year by a state depreciation schedule) multiplied by your local millage; there’s a statewide “legislative tag credit” that lowers the bill some, but it’s applied uniformly across the state so it doesn’t change the county-to-county ranking. Base state fees (registration/privilege) are small and don’t vary by county.
County-to-County comparison
Below is an apples-to-apples snapshot using current county millage totals. If you live inside a city, expect municipal mills (tax rate) to add on top (e.g., in DeSoto: Hernando ~40.76, Southaven ~46.78, Olive Branch ~38.50, Horn Lake ~50.00).
Example math (before the statewide tag credit and standard state fees): assessed value = 30% of MSRP = 0.30 × $35,000 = $10,500; gross tax (ad valorem) = $10,500 × (millage/1000).
What this means in plain English
Tippah County is one of the higher taxed counties in the region, so for the same car you’ll typically pay 25–33% more than in DeSoto or Tishomingo. Benton is the closest to Tippah (only 2% lower).
Inside-city residents in any county will see more taxes (city + school + county). Ripley, for example, adds 14.27 mills.
DeSoto recently cut county rates to blunt reassessment increases; that move also tends to reduce tag costs.
Don’t forget the small stuff (same statewide)
Everyone pays the same state fees on top (or alongside) the ad valorem tax: $14 registration for a new tag (or $12.75 renewal decal), plus a small privilege license fee (e.g., ~$15 for a car), title fee for new purchases, etc.
Those don’t make tags expensive—your local politicians do.
