Oklahoma sales tax 

The statewide sales tax in Oklahoma is 4.50%.  

Like with many other states in the US, local municipalities can also charge sales tax.

The average combined state and local sales tax is 8.99%; however, the maximum local sales tax rate is 7.00%, bringing the maximum sales tax in the state to 11.5%.  

Certain items are exempt from sales tax or have their own special rates. These include: 

  • Prescription drugs are sales tax-exempt 

  • Certain items used in meals or food for school children are tax-exempt 

  • Nearly all items used in production agriculture are tax-exempt 

Oklahoma property tax  

According to data from the U.S. Census Bureau, the average American household spends $2,690 on real estate property taxes.  

In Oklahoma, however, this is much lower, with the median amount paid by homeowners standing at just over $1,400.

In Oklahoma, property taxes are collected on a county level, with each county using its own method of assessing and collecting taxes.  

Oklahoma excise tax

Excise tax is a tax paid on specific goods or services,

In Oklahoma, you pay an excise tax when you purchase a vehicle. This excise tax is 3.25% for new vehicles and a reduced amount for used vehicles.

Oklahoma does have some exemptions for excise tax, including for disabled veterans, if the vehicle is being transferred within the family, transferring between trusts and trustees, or if the vehicle is being transferred as part of a divorce settlement.

Oklahoma motor tax

In Oklahoma, you can expect to pay a combined sales and excise tax rate of 4.5% on all vehicle purchases. This is broken down into a 1.25% sales tax and an excise tax of 3.25%.  

For used car purchases, owners pay a flat fee of $20 for the first $1,500 they spend and must pay the combined rate of 4.5% for the remaining price.  

When purchasing a vehicle, you must also factor in the fuel cost. In Oklahoma, you must pay taxes of $0.19 per gallon on gasoline and $0.16 per gallon on diesel.  

Oklahoma estate tax

Oklahoma does not levy estate tax or inheritance tax.  

However, federal estate tax can still apply if your estate is above a certain threshold ($13.61 million in 2024). 

It’s also important to consider that you may have to pay estate taxes if you inherit an estate from someone in a state that levies it. It’s important to check local regulations to ensure you’re paying the right amount of tax.  

Oklahoma retirement tax

Oklahoma has a lower cost of living than many other states in the US. This is a huge advantage for retirees, especially those on a fixed income looking to make their money go further.  

For retirees aged 65 and older, Oklahoma offers an income tax exemption of up to $25,000, depending on your filing status.

Income from Social Security is also not taxed, meaning retirees hold on to more of their income than they would in other states.  

The state also boasts lower housing, healthcare, and transportation costs than the national average, making it an attractive destination for US retirees.
