Oklahoma Vehicle Sales Tax and Excise Tax: The 4.5% Tag Office Bill Explained

Oklahoma charges a 3.25% motor vehicle excise tax plus a 1.25% sales tax when you title a vehicle, about 4.5% in total on a new vehicle (on a used vehicle the excise part is $20 on the first $1,500 and 3.25% of the rest). Since July 1, 2026, under House Bill 1183, the excise tax is figured on the actual sales price, before any trade-in, instead of a value tied to the average retail price guide. The 1.25% sales tax is figured on the price minus your trade-in. No city or county tax is added.

A vehicle titled to a Montana LLC pays no sales or excise tax in Montana. Through ZeroTaxTags that is our $699 vehicle package plus Montana LLC formation from $175 and a registered agent at $99.99 a year; for an electric vehicle, Montana's own EV fee is passed through at cost. The page below covers the tax math by vehicle, the July 2026 change, how to pay, and the Montana route.

Updated October 2026. House Bill 1183 took effect on July 1, 2026. Oklahoma now figures the 3.25% excise tax on the vehicle’s actual sales price instead of a value tied to the average retail price guide. The rates did not change.

Oklahoma Vehicle Tax: The Short Answer

Oklahoma charges two taxes when you title a vehicle: a 3.25% motor vehicle excise tax and a 1.25% sales tax, about 4.5% in total on a new vehicle. On a new vehicle the excise tax is 3.25% of the price; on a used vehicle it is $20 on the first $1,500 and 3.25% of the rest (68 O.S. 2103). Since July 1, 2026, the excise tax is figured on the actual sales price written on the bill of sale. No city or county sales tax is added.

• New vehicle at $75,000, no trade-in: about $3,375 in excise and sales tax.
• Trade-ins: the 1.25% sales tax is figured on the price minus your trade-in; the 3.25% excise tax is figured on the actual sales price before any trade-in.
• Deadline: the excise tax is late after 30 days, then $1 a day up to the amount of the tax.
• EVs: a yearly fee of $110 for most battery cars and $82 for plug-in hybrids, on top of registration.

Below: how the tax is figured, what changed on July 1, 2026, what it costs on common vehicles, how you pay it, and how Montana LLC registration through ZeroTaxTags fits in.

How the 4.5% Is Figured

The Oklahoma vehicle tax at purchase is two taxes collected together when the vehicle is titled. The excise tax is 3.25% of a new vehicle’s value; for a used vehicle it is a flat $20 on the first $1,500 of value plus 3.25% of the rest (68 O.S. 2103). The excise tax replaces state and local sales taxes on the vehicle, except for a 1.25% state sales tax that still applies to the sale (68 O.S. 2106 and 1355).

Trade-ins treat the two parts differently. The 1.25% sales tax is figured on the difference between your trade-in and the price of the vehicle you buy (68 O.S. 1355). The 3.25% excise tax is figured on the vehicle’s actual sales price before any trade-in (68 O.S. 2104; Service Oklahoma’s June 2026 notice on the change says the same).

No city or county sales tax applies to a vehicle sale, so the rate is the same everywhere in the state. The tax is due when ownership changes or when the vehicle is first registered in Oklahoma. It becomes late after the 30th day, and the penalty is $1 a day, up to the amount of the tax itself.

• Not taxed: transfers without payment between spouses or between parents and children, and transfers into a revocable trust (68 O.S. 2103(C)).
• Inheritance from someone who has died is exempt (68 O.S. 2105(4)).
• Moving to Oklahoma: a vehicle you owned and registered in another state at least 60 days before Oklahoma registration was required is exempt from the excise tax (68 O.S. 2105(2)).
• 100% disabled veterans have an exemption, limited to one vehicle every three years (68 O.S. 2105).

On top of the purchase taxes, Service Oklahoma charges an $11 title fee, a $17 transfer fee and a $1.50 insurance verification fee. Yearly registration for a standard vehicle is $96 in years 1 to 4, $86 in years 5 to 8, $66 in years 9 to 12, $46 in years 13 to 16 and $26 after that. A late renewal costs $1 a day after a 30-day grace period, up to $100.

What It Costs by Vehicle

These are worked examples, not customer records. They show the Oklahoma excise tax (3.25%, or $20 plus 3.25% for a used vehicle) and the 1.25% sales tax on the price, with no trade-in, rounded to the dollar.

Yearly registration ($96 a year for a standard vehicle in its first four years) and the $11 title, $17 transfer and $1.50 insurance verification fees come on top of this. Electric vehicles add the fees in the EV section below.

On the Montana side, our charges are the same for every vehicle in the table: the $699 vehicle package, Montana LLC formation from $175, and a registered agent at $99.99 a year (or $12.50 a month). With annual billing that is $1,373.95 in ZeroTaxTags fees over five years. Montana’s own yearly registration renewal is not included in that figure; for an electric vehicle, Montana’s $130 yearly EV fee is passed through at cost. There is no Montana sales tax or excise tax to add.

What Changed on July 1, 2026

Before July 1, 2026, Oklahoma did not simply tax the price you paid. The value used for the excise tax had to fall within 20% of the vehicle’s average retail value in the pricing guide Service Oklahoma used. On a private sale well below the guide price, that meant tax on a higher number than the buyer actually paid.

House Bill 1183, approved in May 2025, removed that rule. Since July 1, 2026, the excise tax value is “the actual sales price of such a vehicle,” entered on the bill of sale along with the number of tires and the rim diameters (68 O.S. 2104). The 3.25% rate, the 1.25% sales tax and the $20 base for used vehicles did not change.

For buyers today, the practical effect is simple: the bill of sale matters. Make sure it shows the real price, because that is the number the tax is figured on.

EV and Plug-In Hybrid Fees

Oklahoma adds a yearly fee to electric vehicles at registration and each renewal (68 O.S. 6511). By weight:

A $50,000 electric crossover owes $2,250 in excise and sales tax at purchase, then $110 a year on top of registration.

Montana charges its own EV fee too: $130 a year, which we pass through at cost. So for an EV owner the yearly fees are close, and the difference is the purchase tax.

How You Pay It: Dealer vs Private Sale

Since September 2024, Oklahoma uses a three-step timeline (Service Oklahoma):

1. Within 2 business days: the dealer, or the buyer or seller on a private sale, pre-registers the vehicle (online or at a Licensed Operator).
2. Within 10 days: the buyer puts on the plate with its decals.
3. Within 2 months: full registration, title and tax, in person at a Licensed Operator or Service Oklahoma (6015 N. Classen, Oklahoma City).

What to bring: proof of Oklahoma insurance; the title signed over to you (or the manufacturer’s statement of origin for a new vehicle); the purchase agreement, or Form 722-1 (Declaration of Vehicle Purchase Price) for a private sale; Form 701-6 (title application); Form 729 odometer disclosure for 2011 and newer vehicles; and a lien release if the seller had a loan. A vehicle last titled in another state usually needs a VIN inspection.

Penalty: separately from that timeline, the excise tax itself is late after 30 days from the purchase, at $1 a day up to the amount of the tax.

Working or staying in Oklahoma with out-of-state plates: an owner who takes a job in Oklahoma has 30 days to register there (daily commuters from a neighboring state are exempt), and a visitor’s vehicle that stays more than 60 days must be registered (47 O.S. 1125).

The Montana LLC Route

Montana has no general sales tax and no vehicle excise tax, so there is no purchase tax on a vehicle titled there.

ZeroTaxTags forms a single-member Montana LLC for you, with a Montana registered agent and its own federal EIN. The LLC takes title to your vehicle and registers it through a Montana county treasurer, which issues Montana plates. You stay the manager and sole member, with full use of the vehicle; the title is held by the LLC.

Vehicles 11 years and older can get Montana’s permanent registration. Newer vehicles renew once a year, and we handle the renewal for you. One LLC can hold more than one vehicle.

Is This Legal?

On the Montana side, yes. Montana lets a person who lives in another state form a Montana LLC, lets that LLC own a vehicle, and titles and plates vehicles owned by its LLCs. Each step is a public record: the LLC with the Montana Secretary of State, the title with a Montana county treasurer, and the plate issued to the company.

The Oklahoma side is a separate question. Oklahoma’s registration law looks at the owner’s own situation, such as taking a job in the state or keeping a vehicle there for more than 60 days. That is a question about you, not about the plate. If you are not sure how it applies, call us before you buy and we will tell you honestly whether the structure fits.

Our Process and Prices

• LLC formation. We file your single-member Montana LLC, usually the same or next business day: Articles of Organization, registered agent, EIN application and operating agreement.
• Title transfer. We coordinate the title work at a Montana county treasurer’s office, and the title is issued in the LLC’s name.
• Plates. Montana plates ship to you, usually within about a week of starting.
• Yearly upkeep. Our registered agent service keeps the LLC in good standing, including the annual report filing, and we handle the yearly registration renewal.

Our prices: $699 for the car, SUV and truck package; Montana LLC formation from $175; registered agent $99.99 a year or $12.50 a month. See the cars, SUVs and trucks page for what the package includes.

Timeline

Start to finish, about one week from submission to plates in hand. The slowest part is the postal service. Everything we control on our end is typically wrapped in 48 hours.
