Mississippi car tag fees and sales tax

Why the tag costs more than the fees

The state part of a Mississippi tag is small and fixed: a $15 privilege tax and a registration fee of $14 the first time or $12.75 at renewal, which bundles a tag charge, a trauma care fund fee and an extra registration fee. The large part is the ad valorem tax that your tax collector computes for the local governments. The Department of Revenue sets the assessed value at 30% of the manufacturer's suggested retail price, lowered over ten years, with a $100 floor for passenger vehicles. That assessment is multiplied by the combined millage of your county, city and school district, so two neighbors in different towns can pay very different amounts for the same car. A legislative tag credit, funded by sales tax collected on vehicles, then takes a percentage off.

Dealer purchase or private sale

From a dealer, the 5% applies to the price after discounts and the trade-in allowance, but manufacturer rebates are not subtracted. From a private seller, the rule changes completely: the tax collector charges 5% of a value the state assigns to that model, not the price on your bill of sale, and a car ten years old or more owes no sales tax at all. Bring the title and register within 30 business days; the late penalty adds $250 on top of the usual charges. To compare with a neighbor where the tax is mostly a state matter, see Alabama.

Electric and hybrid cars

Electric cars pay an extra yearly tax that the law set at $150, and hybrids one set at $75. Both are raised every July 1 by the previous year's inflation rate, so the amount on your notice is higher than the original figure; the tax collector has the current number. There is no inspection to budget for: Mississippi no longer requires a periodic safety or emissions test for private cars.

What sets Mississippi apart

• Cars and light trucks of 10,000 lb or less pay a 5% sales tax instead of the 7% general rate, on the net price after dealer discounts and trade-in, with manufacturer rebates not deducted (Mississippi DOR).
• A used car bought from a private person is taxed at 5% of a pre-determined value for that kind of car, not the purchase price, and only when it is less than ten years old (Mississippi DOR).
• Every private passenger vehicle pays a $15 annual highway privilege tax to the state (Mississippi Legislature).
• The registration fee is $14 for a first registration and $12.75 for a renewal, collected by the county tax collector (Mississippi DOR).
• The $14 is made of a $5 tag-and-decals fee, a $4 fee for the Mississippi Trauma Care Systems Fund and a $5 additional registration fee; decals alone cost $3.75 instead of $5 (Mississippi Legislature).
• Ad valorem tax is paid with the tag every year, on an assessed value of 30% of the MSRP depreciated over 10 years, with a minimum assessed value of $100 for passenger vehicles (Mississippi DOR).
• Since 1994 a legislative tag credit funded by motor vehicle sales tax revenue lowers that ad valorem tax, and the DOR resets its percentage every year (Mississippi DOR).
• The annual electric vehicle tax was set at $150 and is raised every July 1 by the prior year's inflation rate, rounded to the whole dollar (Mississippi Legislature).
• A Mississippi certificate of title costs $9, or $39 with the 72-hour Fast Track service (Mississippi DOR).
• A vehicle bought in Mississippi must be registered within 30 business days, and missing the 30-day deadline adds a $250 penalty to the usual late penalties (Mississippi DOR).

What the Mississippi calculation cannot know

• Ad valorem tax is due with every tag: 30% of the MSRP, depreciated over 10 years, times the millage your county, city and school district set, less the legislative tag credit the DOR recalculates each year. The millage is not published in one statewide table, so the line has no amount.
• The electric vehicle tax ($150 in Section 27-19-21) and the hybrid tax ($75) are raised every July 1 by the prior year's inflation rate; the indexed amount for the year starting July 1, 2026 was not found on an official page, so the line has no amount and the summary shows the statutory base.
• Whether a plug-in hybrid pays the hybrid tax is assumed from the hybrid definition; the DOR page read only says electric and hybrid fees apply at registration and renewal.
• A private (casual) sale is taxed at 5% of the DOR assessment value for that model, which the form does not ask; the tax line has no amount (vehicles 10 years old or more are exempt).
• Counties may add their own road and bridge privilege tax and cities a municipal privilege tax; they were not read on an official statewide page and are not included.
• No local sales tax is added: the City of Jackson's 1% special tax covers only sales taxed at 7% or more, and the City of Tupelo's 0.25% levy on retail sales was not confirmed for vehicles.
• Whether a dealer documentation fee is part of the taxable price was not stated in the pages read; the engine leaves it out. No cap on that fee was read in Mississippi law.
