County Assessor



Each year you receive a tax statement based on the value of your property, but do you know where the money goes? Do you know what you are paying for?

The attached Tax Levy Table is an example illustrating how ad valorem tax on a $100,337 property is used.


Since the county assessment ratio is 11%, this property has an assessed value of $11,037. ($100,037 x .11). The property owner filed for Homestead Exemption, so the taxable value was reduced to $10,037.

The description column on the tax table identifies entities which receive money from the value of this property. These include:

Logan County Government, with a millage of 16.89, receives $169.52. This money is used to fund various county offices, such as that of county clerk, assessor, treasurer, sheriff and health department.

The Guthrie School District, at 43.96 mills, gets $441.23. This is allocated for the general fund, building fund and EMS district. (Millage rates for schools differ based on the district in which one resides.)

Vo-Tech District 16, with a millage rate of 15.37, receives $154.27 for their general fund and building fund. All of this adds up to a total tax rate of 76.22 mills, and a total property tax of $765. Some Tax Levy Tables also include a Fire District millage, but this property was not subject to that tax due to its location.

A frequent question we receive at the assessor’s office is, “If a school bond passes, will it affect my property tax?”

Here is basic information about how to compute your property tax.

First, find the fair cash value of your home. This information is available through the “Search Records” link on this web page or by calling our office at 282-3509.



1. If the fair cash value of your home is $100,000, multiply $100,000 x .11. This amounts to $11,000, the assessed value of your property. (11% is the county assessment ratio).

2. If you have Homestead Exemption, subtract $1000 from $11,000.

3. Multiply the remaining $10,000 by the current tax rate of the school district in which you live. (See tax table.) If you live in Crescent School District, multiply $10,000 by .09484. In Edmond, by .09705. In Guthrie, by .07622. Convert to decimals since a mill is $1 per $1000 of assessed value, or .001.

4. If you use the 76.22 millage rate, multiply $10,000 x .07622. This amounts to $762 in property tax.

If a bond issue increases the tax rate by 15.67 mills, add 15.67 to 76.22. The new millage rate will be 91.89.

5. Using the revised rate, compute your new tax by multiplying $10,000 x .09189. Your property tax is now $919.

If you live in Oak Cliff or Woodcrest Fire Districts, you must also include an additional tax. The Oak Cliff levy is .00722. Woodcrest is .006.

To compute this, multiply the initial assessed value of $11,000 in the example above by the appropriate fire district levy.

Example: $11,000 x .006 = $66. Add this to $919. Your total tax is now $985.

Valuation Notices Mailed March 2

Each year, the county assessor is required by law to mail a Notice of Increase in Valuation of Real, Commercial and Personal Property to those whose property has increased in value. This year, the Logan County Assessor’s office mailed notices March 2. The notice is NOT a tax bill. It is information which provides you an opportunity to review the assessed value of your property and to contact the assessor’s office if you have questions. 

We do not mail notices if values remain the same or are lowered.

Some reasons for a valuation increase commonly include the following:

  • Overall market values for properties in your area increased
  • There was new construction on the property
  • The property changed ownership and the previous owner’s exemptions or “cap” were removed as a result of the sale
  • Field appraisers performing visual inspection observed real property undervalued or not previously placed on the assessment roll

As a taxpayer, if you disagree with the value placed on your property, you have an opportunity to appeal. This appeal must be made within thirty (30) days of the mailing date of the notice.

Appeals must be submitted on Oklahoma Tax Commission (OTC) Form 974. This form is available from the assessor’s office or can be downloaded from the website under “Forms.”

Please provide documentation supporting your appeal at the time of the informal hearing.

The complete appeals process is described on the Notice of Increase in Valuation.

Exemptions Offset Valuation Increases

Click on the “Important Dates” link on this website to access information about exemptions which may lower your taxes and help offset any increase in valuation.

The example below illustrates the change in valuation process and how filing for Homestead Exemption can decrease your tax bill.


The example above indicates the current year’s fair cash value on a home increased from $261,632 to $288,893. Because this property did not have Homestead Exemption, it was subject to a 5% increase. A new improvement, a fence, valued at $500, was added to the assessment. This brought the current year’s taxable value to $275,213. The formula is as follows:

$261,632 x 5% = $13,082

Now add the 5% increase and the $500 improvement:

$261,632 + $13,081 + $500 = $275,213

The taxable value for the 5% increase is $275,213

Had the homeowner filed for Homestead Exemption, the preceding year’s amount of $261,632 would have increased by only 3%. The formula would be:

$261,632 x 3% = $7,849

$261,632 + $7,849 + $500 new improvements = $269,981.

The taxable value for the 3% increase would have been $269,981.

As always, if you have questions, feel free to contact the assessor’s office at 405.282.3509. I and my staff are happy to do our best to respond to your inquiries and to assist you in completing any exemption applications.

Why Did Your Property Tax Go Up? - Read the blog post from Representative Jason Murphey.



Tisha Hampton

"As the newly elected Logan County Assessor, I am committed to establishing Fair and Equitable property values."

1890 - Congress passes the Organic Act. Oklahoma became a territory of the United States when Congress passed the Organic Act on May 2, 1890. Section six of the Organic Act states that all property must be taxed in proportion to its value, which is the meaning of ad valorem, a Latin phrase that means "according to value." Today taxable property is valued in proportion to its value, or as a percentage of its value, just as it was when Oklahoma was known as the Oklahoma Territory.

Over the past few months I have talked to hundreds of Logan County residents and have taken careful note of their concerns. I will keep these concerns in mind as I conduct the review process. I will maintain an open-door policy and I intend to release a periodic update with explanations as to what the law provides. I want to establish a website that will be helpful to the property owners. I will carefully review your file and ensure that your property is assessed in a fair manner.

Thank you for providing this opportunity to serve as your County Assessor. I am honored by your trust and anxious to get to work on your behalf.
