Key Takeaways

• Oklahoma's documentary stamp tax is $0.75 per $500 of consideration: Paid at the county clerk's office when the deed is recorded, this transfer tax costs $150 on a $100,000 sale. Unlike most closing costs, it is technically negotiable between buyer and seller, though sellers customarily pay it in Oklahoma.
• Cimarron County's effective property tax rate is approximately 0.43%, among the lowest in the country and the lowest median property tax burden in Oklahoma — itself a low-tax state. Tax-Rates.org reports a median annual property tax of roughly $244 in the county, the 77th-ranked (lowest) of Oklahoma's 77 counties. The county's assessment ratio runs approximately 11–13.5% of fair cash value under Oklahoma's ad valorem system.
• The county is defined by panhandle dryland wheat, grain sorghum, and shortgrass cattle grazing in steep long-run decline: Cimarron County covers roughly 1,841 square miles in the far western tip of the Oklahoma panhandle and is the only U.S. county that touches four other states (Colorado, Kansas, New Mexico, and Texas). Its population peaked near 5,400 during the 1930 Dust Bowl era and has fallen to roughly 2,000 today, according to U.S. Census data — the least-populous county in Oklahoma.

How Can You Sell Land in Cimarron County Oklahoma?

Selling land in Cimarron County, Oklahoma involves a documentary stamp tax of $0.75 per $500, a title-company or attorney closing with the deed recorded at the County Clerk's office, and a thin rural land market shaped by Oklahoma panhandle dryland wheat, grain sorghum, and shortgrass cattle grazing — with a long, steep history of depopulation. The county seat is Boise City. Cimarron County sits at the westernmost point of the Oklahoma panhandle, the only county in the United States that touches four other states (Colorado, Kansas, New Mexico, and Texas) — a five-state geographic crossroads on the High Plains, with Oklahoma's highest point, Black Mesa, rising in its northwest corner.

This guide covers Oklahoma's ad valorem property tax system, the title-and-closing process, how Cimarron County compares to its panhandle and northwest-Oklahoma neighbors, and practical steps for landowners ready to sell. For a full overview of the Oklahoma land sale process, see our guide on how to sell land in Oklahoma.

What Are the Tax Costs of Holding Land in Cimarron County?

Oklahoma's property tax system is administered at the county level. Each county assessor determines fair cash value for all real property, then applies the state-mandated assessment percentage to arrive at taxable assessed value. For most real property in Oklahoma — including vacant land, rangeland, dryland cropland, and rural acreage — the assessment ratio runs between approximately 11% and 13.5% of fair cash value, depending on the assessor's determination and any applicable exemptions, according to the Oklahoma Tax Commission's ad valorem guidelines.

Cimarron County's millage rate, applied to the assessed value, produces an effective tax rate of approximately 0.43% of fair market value — among the lowest in Oklahoma and far below the national average of roughly 0.9%, according to PropertyTax101 and Tax-Rates.org data. The median property tax in Cimarron County is approximately $244 per year on a median home value of roughly $56,400 — the lowest median property tax burden of any county in the state.

For a vacant 160-acre parcel of panhandle grazing land in Cimarron County, the math works as follows at a simplified level: a parcel with a fair cash value of $80,000, assessed at 11% ($8,800 assessed value), at a representative millage rate, produces an annual tax bill well under $500. The exact figure depends on the specific millage rates for the school district, county, and any special levies applicable to the parcel's location.

Agricultural Use-Value Assessment

Oklahoma allows qualifying agricultural land to be assessed on its use value — its capacity to produce agricultural income — rather than its full market value. For Cimarron County's working rangeland and dryland wheat and sorghum ground, this ag use-value treatment can hold assessed values well below what a comparable parcel would carry if assessed at market. Land enrolled in genuine agricultural use, such as cattle grazing or wheat production, generally benefits from this lower basis. A change in use — for example, taking grazing land out of production — can trigger reassessment, so confirm the current classification with the county assessor before assuming a particular tax figure carries forward to a buyer.

Oklahoma's Ad Valorem Calendar and Delinquency

Oklahoma property taxes are assessed as of January 1 each year. Tax bills are issued in the fall and are due in two equal installments: the first by December 31, and the second by March 31 of the following year. Taxes not paid by the March 31 deadline begin accruing interest. After three years of delinquency, the county treasurer can offer the property for resale — a process distinct from a tax lien sale in other states.

Out-of-state landowners holding Cimarron County parcels sometimes fall behind on tax payments because Oklahoma does not require lenders to escrow property taxes on rural land loans the way residential mortgage servicers do — and because the panhandle's distance from the rest of the state makes absentee ownership common. If your property has accumulated back taxes, our guide on selling land with back taxes explains how delinquent amounts are handled at closing.

Beyond taxes, holding costs for Cimarron County land include liability coverage, fence and windmill or water-well maintenance on grazing tracts, and weed and erosion control on dryland fields. On the High Plains, water is the defining long-run risk: much of the irrigated acreage in the panhandle draws on the Ogallala Aquifer, which has been declining for decades, so irrigated cropland values can shift with well capacity and pumping cost over time.

What Zoning and Closing Rules Apply to Cimarron County Land?

Cimarron County is one of the most sparsely populated and lightly regulated counties in Oklahoma, and the vast majority of rural land falls outside any municipal zoning. Most parcels are open rangeland, dryland farm ground, or scattered homesteads with no formal land-use classification beyond their agricultural assessment. Any zoning that exists is concentrated within the limits of Boise City, the county seat. For a typical out-of-town grazing or cropland parcel, the practical questions for a buyer are access (county road or section-line easement), water rights and well status, fencing condition, and whether minerals are severed — not zoning approvals.

Oklahoma has no mandatory attorney-required closing law for real estate transactions. Closings are commonly handled by title insurance companies, escrow officers, or abstract companies, with attorneys often involved when title issues arise. A title company or attorney typically prepares the deed, runs a title search or examines the abstract, issues a title commitment and policy, collects and disburses funds, and records the deed.

A clean Cimarron County land closing usually follows these steps:

1. Sign a purchase agreement with price, parcel legal description, and closing date.
2. Open title/escrow with a title company or closing attorney, who searches title (or examines the abstract) for liens, severed minerals, easements, and delinquent taxes.
3. Clear title issues — pay off any back taxes, release old liens, and resolve heirship or boundary questions.
4. Prepare and sign the deed (typically a warranty or special warranty deed) and settlement statement.
5. Record the deed with the Cimarron County Clerk, who collects the documentary stamp tax at recording and enters the conveyance into the county land records.

Deeds in Cimarron County are recorded with the Cimarron County Clerk at the Cimarron County Courthouse, Courthouse Square on Main Street, Boise City, OK 73933, (580) 544-2251. The County Clerk acts as the agent of the Oklahoma Tax Commission for documentary stamp tax collection. Stamps are affixed to the deed at recording.

Documentary Stamp Tax: The Calculation

Oklahoma's documentary stamp tax is $0.75 per $500 of consideration (or fraction thereof), per the Oklahoma Tax Commission's Chapter 30 rules. The formula: divide the sale price by 500, round up to the nearest whole number, multiply by $0.75. For example:

• $50,000 sale: $50,000 ÷ 500 = 100 × $0.75 = $75
• $100,000 sale: $100,000 ÷ 500 = 200 × $0.75 = $150
• $250,000 sale: $250,000 ÷ 500 = 500 × $0.75 = $375

The tax is negotiable between buyer and seller but is customarily paid by the seller. Certain transfers are exempt, including transfers to government entities, gifts with no consideration, and some foreclosure-related conveyances. Questions about the paperwork involved are covered in our paperwork needed to sell land guide.

For Cimarron County land, title and closing fees follow standard Oklahoma rates; many panhandle transactions still rely on an abstract that is updated and examined by an attorney before title insurance is issued, according to the Old Republic Title fee schedule for Oklahoma. Property tax questions and current assessed value can be confirmed through the Cimarron County Assessor at the courthouse in Boise City, (580) 544-2701.

How Does Cimarron County Compare to Neighboring Oklahoma Counties?

Cimarron County's 2020 Census population was 2,296, down from 2,475 in 2010 and estimated near 2,059 in 2025, according to U.S. Census and WorldPopulationReview data — the least-populous county in Oklahoma. The decline is long-run and steep: the county was the epicenter of the 1930s Dust Bowl, peaked near 5,408 residents around 1930, and has lost more than half its population since, with working-age outmigration toward larger towns and out of the region entirely.

A note on geography: Cimarron County is the only U.S. county that touches four other states — Colorado, Kansas, New Mexico, and Texas — so most of its borders are out of state. Within Oklahoma it is adjacent to only one county, Texas County, directly to the east. The comparison below therefore uses Texas County (the next panhandle county east), Beaver County (the easternmost panhandle county), and Harper County (a comparable rural northwest-Oklahoma county just east of the panhandle) rather than a ring of in-state neighbors.

Factor	Cimarron County	Texas County	Beaver County	Harper County
Population (2020 Census)	2,296	21,384	5,049	3,272
Population trend (2010–2020)	Declining	Growing	Declining	Roughly flat
Effective tax rate	~0.43%	~0.6%	~0.78%	~0.64%
County seat	Boise City	Guymon	Beaver	Buffalo
Primary land character	Dryland wheat / sorghum / shortgrass grazing	Irrigated corn / feedlots / wheat	Wheat / sorghum / grazing	Wheat / grazing / oil and gas

All four counties sit on the High Plains and share a dryland-and-grazing character with thin populations and large average farm sizes. Cimarron County's defining feature relative to its neighbors is its extreme position — westernmost in the state, highest in elevation, and most remote — which makes its land market the thinnest of the group. Texas County to the east is the panhandle's population and agriculture anchor, with extensive Ogallala-irrigated corn, large feedlots, and the regional hub of Guymon, which gives it the highest tax base and the only growing population of the four. Beaver County, the easternmost panhandle county, mixes wheat, sorghum, and grazing on a smaller scale. Harper County, just east of the panhandle, blends wheat and grazing with oil-and-gas activity in the Anadarko Basin. Across all four, the buyer pool for raw land is small and largely composed of neighboring operators expanding their grazing or farming base, plus a handful of out-of-state recreational and investment buyers.

Economy and Major Employers

Cimarron County's economy centers on cattle ranching, dryland and irrigated farming, and a small public sector anchored in Boise City. With roughly 2,000 residents and no large town, employment leans heavily on agriculture, the county and city governments, the school district, and basic local services. The county straddles the Central and Mountain time zones and remains one of the most isolated places in Oklahoma, hours from any metro area.

The 2022 USDA Census of Agriculture counted 432 farms in Cimarron County covering 1,155,696 acres of farmland — meaning roughly 98% of the county's land area is in agriculture — with an average farm size of 2,675 acres, among the largest in the state. Total market value of agricultural products sold was $354,260,000, with livestock and poultry accounting for roughly 83% of sales and crops about 17%, a profile that reflects the county's heavy emphasis on cattle. Of the land in farms, roughly 714,757 acres are pastureland and 420,400 acres cropland, with only about 33,274 acres irrigated (3% of land in farms). Top crops by acreage are wheat for grain (75,530 acres), grain sorghum (62,479 acres), and corn for grain (17,129 acres), and the county reported 117,812 cattle and calves — capturing the dryland-grain-and-grazing mix that defines the local land market.

What Are Your Options for Selling Land in Cimarron County?

Cimarron County land tends to fall into a few categories for sellers: working shortgrass rangeland and pasture, dryland wheat and sorghum cropland, and irrigated circles tied to Ogallala wells. Each category faces the same basic reality — the county's tiny local population (around 2,000 residents) and remote panhandle location mean much of the demand comes from neighboring operators and out-of-state buyers, and reaching that audience requires either listing with a land-specialized broker, using platforms like Land.com or LandWatch, or selling directly to a land investment company. If your acreage is grazing ground that is no longer being run, our guide on selling pasture or grazing land no longer farmed walks through the considerations, and if it is active crop and grain ground, see our selling farmland guide.

For remote, off-grid tracts with no utilities — common in this corner of the panhandle — our guide on selling recreational or off-grid land with no utilities covers what buyers weigh on land far from services. If you live elsewhere and are trying to sell a Cimarron County parcel from out of state, our selling land as an out-of-state owner guide addresses the logistics. For a grounded understanding of what factors affect your parcel's value before requesting any offer, see our how much is my land worth guide, and if you are weighing whether to list, our do you need a realtor to sell land guide compares your paths.

The annual carrying cost on even a low-taxed Cimarron County parcel adds up over time: at the county's approximate 0.43% effective rate, a parcel with a fair cash value of $100,000 generates roughly $430 per year in taxes — modest individually, but 10 years of non-productive holding equals $4,300+ in taxes alone before fencing, water-system upkeep, and weed control. A thin buyer pool, the remote location, and Ogallala water uncertainty on irrigated ground can also stretch out a traditional listing, since buyers and their lenders work through title and water due diligence before closing.

To confirm parcel details, current assessed value, or any delinquent balance before you sell, the Cimarron County Assessor (580) 544-2701 and Treasurer (580) 544-2261 are both at the Cimarron County Courthouse on Courthouse Square, Main Street, Boise City, OK 73933, and deeds are recorded with the County Clerk (580) 544-2251 at the same courthouse.

Jerez Land buys Oklahoma land for cash. We provide parcel-specific written offers — not ranges or per-acre formulas — based on the specific acreage, location, access, water and well status, grazing or crop condition, surface-versus-mineral status, and legal standing of your parcel. Because we buy as-is and take on the carrying, marketing, and resale risk ourselves, our offer reflects a wholesale cash price rather than a retail listing number, and that is the trade-off for a fast, certain close with no agent commissions and no listing period. We coordinate the title and closing process on our side. Request a cash offer and we will respond with a firm written number.

You can list with a land broker, use online platforms, or request a direct cash offer from a land buyer.

What is the property tax rate in Cimarron County Oklahoma?

Cimarron County's effective property tax rate is approximately 0.43% of fair market value — the lowest median property tax burden of any county in Oklahoma and well below the national average of roughly 0.9%. Oklahoma assesses real property at approximately 11–13.5% of fair cash value, and the county's millage rates applied to that assessed value produce a median annual property tax of around $244. Qualifying agricultural land may be assessed on its use value rather than full market value.

How much is Oklahoma's documentary stamp tax?

Oklahoma's documentary stamp tax is $0.75 per $500 of consideration, or fraction thereof. To calculate: divide the sale price by 500, round up to the nearest whole number, and multiply by $0.75. On a $100,000 land sale the tax is $150; on a $200,000 sale it is $300. The tax is collected by the County Clerk when the deed is recorded and is customarily paid by the seller, though it is negotiable.

Where do I record a deed in Cimarron County Oklahoma?

Deeds are recorded with the Cimarron County Clerk at the Cimarron County Courthouse on Courthouse Square, Main Street, Boise City, OK 73933, (580) 544-2251. The County Clerk also collects Oklahoma's documentary stamp tax at recording and acts as the agent of the Oklahoma Tax Commission for that purpose. A title company or closing attorney typically prepares the deed and handles recording as part of the closing.

Why is Cimarron County's population so low and still declining?

Cimarron County is the least-populous county in Oklahoma, with roughly 2,000 residents today. It was the epicenter of the 1930s Dust Bowl, peaked near 5,400 residents around 1930, and has lost more than half its population since through decades of farm consolidation and outmigration. The county's remote position at the far western tip of the panhandle — the only U.S. county touching four other states — keeps the local buyer pool for land small, so most demand comes from neighboring operators and out-of-state buyers.

Is the Ogallala Aquifer a concern when selling irrigated land in Cimarron County?

It can be. Much of the panhandle's irrigated cropland draws on the Ogallala Aquifer, which has been declining for decades, so a well's current capacity and the cost of pumping affect what irrigated ground is worth and how a buyer underwrites it. Dryland wheat, sorghum, and grazing tracts are not directly tied to well capacity, but for irrigated parcels, documenting well status and water rights up front helps a sale move faster. The title and closing work will reflect whatever water rights and mineral interests convey with the surface.
