Use the Oklahoma Tag Cost Calculator below to estimate your annual vehicle registration and excise tax fees. The cost is primarily determined by the vehicle’s original value and its current age.

Oklahoma Tag Cost Formula (Excise Tax Component)
*Note: Depreciation Factor and Rate are tiered based on vehicle age (A).*

Variables Used in the Calculator
- Original MSRP: The vehicle’s Manufacturer’s Suggested Retail Price when new. This is the base value used for calculating the depreciation schedule, not the current market value.
- Vehicle Age (Years): The number of years passed since the vehicle’s model year. This factor determines the applicable depreciation tier and tax rate.
- Fixed County/Agency Fees: Miscellaneous flat fees applied by county tag agencies, which are fixed regardless of the vehicle’s value or age (e.g., mail fees, processing fees).

What is the Oklahoma Tag Cost?
The “tag cost” in Oklahoma is primarily composed of the state’s Motor Vehicle Excise Tax (sometimes referred to as the Title Fee) and a host of smaller, mandatory registration fees. Unlike many states that base registration fees purely on weight or a simple flat rate, Oklahoma employs a depreciation-based schedule for its excise tax.
This means a brand new vehicle has a significantly higher annual fee than a 15-year-old vehicle because the excise tax calculation is tied to the vehicle’s original MSRP, which is then depreciated over time based on the age of the vehicle. This tiered system ensures fees reflect the vehicle’s lifetime value and is a major revenue source for the state and local governments.
It’s important to note that the actual fees can vary slightly between county tag agents due to specific local charges, which is why we include the “Fixed County/Agency Fees” field in our estimation tool.
How to Calculate Oklahoma Tag Cost (Example)
- Determine the Vehicle’s Original MSRP: Locate the MSRP from the original sales paperwork or a reliable online valuation tool. For our example, let’s use $45,000.
- Identify the Vehicle’s Age Tier: Determine the vehicle’s age in years. For example, a vehicle that is 6 years old falls into the Year 5-8 tier.
- Apply the Depreciation Factor and Rate: According to the state’s schedule for the 5-8 year tier, the base value is depreciated (e.g., to 75% of MSRP) and taxed at the appropriate rate (e.g., 2.25%).
- Calculate the Excise Tax: ($45,000 × 75%) × 2.25% = $33,750 × 0.0225 = $759.38.
- Add Fixed Fees: Include any flat, mandatory fees (e.g., a $20 plate fee, $5 processing fee, etc.). Total fixed fees = $25.00.
- Determine Total Tag Cost: Sum the Excise Tax and Fixed Fees: $759.38 + $25.00 = $784.38.
Frequently Asked Questions (FAQ)
Yes. The primary component, the Motor Vehicle Excise Tax, is based on a sliding scale of depreciation. As your vehicle gets older, the taxable value decreases, and therefore your annual tag cost will typically decrease until it reaches a low, flat minimum fee after about 13 years.
Oklahoma does not charge a traditional “sales tax” on vehicles. Instead, they charge the Motor Vehicle Excise Tax, which is a one-time fee paid upon initial titling, but the annual tag renewal fee is a separate and distinct cost calculated here.
For vehicles 13 years old and older, the excise tax component typically drops to a low flat rate, such as $20 or $30, though you still must add fixed county and agency fees, resulting in a minimum total cost usually around $50-$60.
The tag cost calculation is still based on the original MSRP when the car was new, regardless of how many times it has been sold. The only factor that changes the annual fee is the current age of the vehicle.
