Oklahoma County Property Taxes 2026: Due Dates and Rates for Edmond, Deer Creek and North OKC

When Are 2026 Oklahoma County Property Taxes Due?

According to the Treasurer's calendar, this is how the season runs:

• October to November: current tax statements are mailed.
• Nov. 1: taxes first become due and payable.
• Dec. 31, 2026: last day to pay the full amount or the first half before taxes become delinquent. Mortgage companies must pay the full amount by this date.
• Jan. 1, 2027: if nothing was paid by Dec. 31, the full amount is delinquent and interest is added.
• Mar. 31, 2027: last day to pay the second half.

The Treasurer's general information page adds the fine print. Interest on delinquent payments is 18% a year, added monthly on the 15th at 1.5%. The office cannot accept a first-half payment after Dec. 31, and failing to receive a statement is not a legal reason to waive interest.

In short, a missing statement does not move the deadline.

Why Do Two Edmond-Address Homes With the Same Value Get Different Tax Bills?

Because a mailing address is not a tax district. Each parcel is taxed by the school district, county, career-tech district and, inside city limits, the city that cover it. The Oklahoma State University mill levy report lists Edmond Public Schools and Deer Creek parcels both inside City of Edmond limits and inside Oklahoma City limits, so two homes with Edmond addresses can sit in different tax districts.

Here are the school-district levies from the Assessor's Levy History, in mills ($ of tax per $1,000 of assessed value), plus 2025 totals by city limits:

As of Nov. 1, 2026, the Assessor's Levy History has no 2026 column, so 2025 is the latest published year. The totals come from the OSU report's Oklahoma County table (2025 levies). Each adds the school levy, 23.14 county-wide mills and the career-tech district levy (15.69 mills for Francis Tuttle in the first three rows, 19.11 for Oklahoma City Public Schools). Inside Oklahoma City limits, add 15.16 mills for the city. The report lists no City of Edmond levy, so the Edmond column adds none. Totals do not include fire protection district levies.

On those 2025 numbers, Deer Creek runs 9.19 mills above Edmond Public Schools. On a home with $33,000 of assessed value (a $300,000 home at the 11% ratio), that gap works out to about $303 a year. That is arithmetic on last year's rates, not a forecast.

For scale, the OSU report shows 2025 totals across Oklahoma County districts running from 87.8 to 140.78 mills, with a mean of 113.51. Parts of the Deer Creek area also sit in a fire protection district with its own levy, so look up your own parcel on the Oklahoma County Assessor site before comparing neighborhoods.

How Is a Home's Taxable Value Calculated?

The Assessor's figuring taxes guide uses four steps: know the taxable market value, apply the assessment ratio (11% for real property), subtract any exemptions, then multiply by the tax rate for your area. The Assessor defines fair cash value as the price a willing, knowledgeable buyer and seller would agree on with neither under pressure.

Here is an illustration with round numbers. It is not a real address, district or rate:

• Taxable market value: $300,000
• Times the 11% assessment ratio: $33,000 assessed value
• Minus the $1,000 homestead exemption: $32,000
• Times 100 mills ($100 per $1,000): $3,200

The Assessor's own example is a $50,000 taxable market value with a homestead exemption at $100 per thousand, which comes to $450. Your district's millage is the variable that moves the answer.

One thing that does not move it: if you saw the news about Edmond's nominated Opportunity Zones, that is a federal investor incentive, and as covered in my post on Edmond's Opportunity Zone nominations, it does not change local property taxes.

How Does the Homestead Cap Work, and What Happens When a Home Sells?

Article X, Section 8B of the Oklahoma Constitution limits how much a property's taxable value can rise in a year: 3% for homestead and agricultural property and 5% for everything else. According to the Assessor, the limit does not apply if improvements were made or if title to the property is transferred, changed or conveyed to another person. The 3% homestead limit comes from State Question 748, passed in 2012.

The cap limits how fast taxable value can climb. It does not freeze millage, so a bill can still move when levies change. Think speed limit, not parking brake.

A sale is the big reset. The Assessor's deed codes say a sale between non-family members removes the cap and exemptions, so taxable value starts over at fair cash value. That is why a seller's long-held tax bill and a buyer's first one can be very different numbers.

Not every transfer resets it. The same list says divorce decrees and correction deeds retain the cap and exemptions, and family transactions and probated estates retain the cap but remove exemptions.

Which Exemptions Should Homeowners Check, and When Are the Deadlines?

The Assessor lists these on its exemptions pages. Applications for homestead, additional homestead and the senior freeze run Jan. 1 through Mar. 15.

• Homestead: exempts $1,000 of assessed valuation. You must own and live in the home on Jan. 1, with the deed executed by Jan. 1 and filed with the County Clerk by Feb. 1. Once granted, it does not need to be renewed unless you change the deed or move.
• Additional homestead: another $1,000 for a head of household who qualifies for homestead and meets a household income limit. Confirm the current income limit with the Assessor's office before filing.
• Senior valuation freeze: for a homestead owned by someone 65 or older before Jan. 1 whose gross household income does not exceed the HUD median income level for the previous year. It holds taxable market value steady, not the tax bill, and it ends if the owner stops owning or living there, income exceeds the limit or improvements are made.
• Disabled veterans: a 100% permanently disabled veteran, or the surviving spouse of one, may qualify for an exemption covering the homestead's full fair cash value, subject to several requirements.

This is general information, not tax advice. For your parcel, check with the Oklahoma County Assessor, the Treasurer or a tax professional.

I Just Bought a Home. Who Pays This Year's Bill?

The county bills the property's owner of record. The Treasurer says the Assessor certifies accounts to its office on Oct. 1, and new owners should give the Assessor the correct mailing address before Sept. 30. If your lender pays your taxes, the Treasurer notes that most mortgage companies pay through a third-party tax service, so a payment can take a bit to show as paid.

The split between buyer and seller comes from the contract. Section 11A of the Oklahoma Real Estate Commission's 2026 Residential Sale contract prorates general ad valorem taxes for the current calendar year through the date of closing. If the amount has not been fixed, it uses the previous year's levy rate and the most current assessed value available at closing. Your own contract controls, and your title company or attorney can confirm how it applies.

Then comes the homeowner's homework: since a sale removes the old exemptions, a new owner who qualifies has to apply for homestead by Mar. 15.

The Bottom Line

Dec. 31 is the date that matters for the first half or the full amount, and Mar. 15 is the exemption deadline. The 2025 table is for comparing districts, not for predicting your bill, because the 2026 rates are not out yet. Do you know which school district your tax bill is for?

Frequently Asked Questions

When is the first half due?

The first half or the full amount is due by Dec. 31, 2026, according to the Oklahoma County Treasurer. Taxes first become due and payable Nov. 1, and the second half is due Mar. 31, 2027 if the first half was paid on time.

What happens if I pay after Dec. 31?

If nothing is paid by Dec. 31, the full amount becomes delinquent Jan. 1 and interest is added, according to the Oklahoma County Treasurer. Interest is 18% a year, added monthly on the 15th at a rate of 1.5%. The Treasurer cannot accept a first-half payment after Dec. 31, and failing to receive a statement is not a legal reason to waive interest.

Is the Deer Creek millage higher than Edmond Public Schools?

Yes, on the latest published levies. The Oklahoma County Assessor's Levy History lists a 2025 school-district levy of 75.52 mills for Deer Creek and 66.33 mills for Edmond Public Schools. Inside City of Edmond limits, which carries no city levy in the Oklahoma State University mill levy report, the 2025 totals are 114.35 versus 105.16 mills. Inside Oklahoma City limits they are 129.51 versus 120.32. The 2026 levies were not posted as of Nov. 1, 2026, so confirm your parcel's millage with the Assessor.
