Johnson County Arkansas Property Tax Calculator

How Johnson County property taxes are calculated

Arkansas assesses real property at 20% of market value. Johnson County then multiplies that assessed figure by the total millage for the parcel's school district and city, where one mill equals $1 of tax per $1,000 of assessed value. The $600 homestead credit comes off last, and only a qualifying primary residence can claim it.

Here is the working for a $300,000 home in Coal Hill, inside the Westside #40 district, which carries 57.3 mills for 2026 collections, the highest published rate in the county:

1. $300,000 market value times 20% equals $60,000 assessed value.
2. $60,000 times 57.3 divided by 1,000 equals $3,438 tax before credit.
3. Subtract the $600 homestead credit to reach $2,838 estimated annual tax, or $236.50 a month.

Move the same house out to the rural tier of Deer/Mount Judea #2 at 33 mills of school levy, the cheapest row the state published for Johnson County, and the tax before credit falls to $2,598, or $1,998 after the credit. Identical house, about $840 less a year. Johnson County's assessor also states the 20% rule in plain terms on the county's own page: residential, commercial and personal property are each assessed at 20% of fair market value, with commercial land treated the same way.

Johnson County millage rates by district and city

Every row below is a taxing combination published for Johnson County for 2026 collections, with school, city and county columns reconciling to the overall figure. Seven school districts touch the county and five cities levy a tax, producing thirteen rows.

Johnson County rows are from the Arkansas DFA Assessment Coordination Division 2025 Millage Report, covering 2026 collections and issued March 2026. The report lists thirteen taxing combinations for the county, all shown above.

Why Johnson County property tax rates differ by address

Johnson County has the widest rate spread of the five counties rebuilt in this batch, 14 mills from top to bottom, and the reason is visible in one line of the table: a Clarksville address appears twice, once in the Clarksville #17 district and once in the Lamar #39 district, at 51.8 and 52.48 mills.

• Cheapest combination: rural Deer/Mount Judea #2 at 43.3 mills. That district levies the county's lowest school rate at 33 mills, and the rural tier adds no city tax on top of the flat 10.3 mill county rate.
• Dearest combination: Coal Hill inside Westside #40 at 57.3 mills. Westside #40 levies 42 school mills and Coal Hill adds 5 city mills on top of the 10.3 county rate. Coal Hill also sits in the district whose school levy is the county's second highest, so the two factors stack.
• Clarksville sits inside two school districts, the only Johnson County town that does. A Clarksville address in the Clarksville #17 district pays 51.8 mills, and a Clarksville address in the Lamar #39 district pays 52.48 mills. The city levy is identical at 2.2 mills in both cases, so the entire 0.68 mill difference comes from the school district. Two neighbours inside the same city limit can be on different rows of the table above.
• Clarksville also has the county's lowest city levy. At 2.2 mills it is less than half the 5 mills charged by Coal Hill, Knoxville and Lamar. That is why Clarksville, the county seat and largest town, carries a lower overall rate than Knoxville or Lamar despite sitting in a similar school district.
• Hartman and Coal Hill land 0.3 mills apart on the same school district. Both sit in Westside #40 and pay the 10.3 mill county rate, so the 57.0 against 57.3 difference is entirely the city levy: 4.7 mills in Hartman against 5 in Coal Hill.
• Five districts fringe in from neighbouring counties. Lamar reaches into Pope County, Deer/Mount Judea from Newton, Dover from Pope, Jasper from Newton into Boone, Carroll, Franklin, Johnson and Madison, and Ozark from Franklin. All five arrive as rural tiers, and the Dover row at 53.8 mills is the highest rural tier in the county.
• The county levy is flat at 10.3 mills everywhere. It is the highest county levy of the five in this batch, and it is the same in every row, so no Johnson County parcel gains or loses from a county tier split.

Johnson County cities and communities

Clarksville

Clarksville is the county seat and the largest city, and it is the only Johnson County town sitting inside two school districts. A Clarksville address pays 51.8 mills in the Clarksville #17 district and 52.48 mills in the Lamar #39 district, with the 2.2 mill city levy identical either way. Clarksville's city levy is also the lowest in the county, which is why the county seat carries a lower total than Knoxville or Lamar. The assessor's office is at 108 S. Fulton Street and the collector's office works from P.O. Box 794, both in Clarksville.

Coal Hill

Coal Hill carries the highest rate in the county at 57.3 mills and the county's second-highest city levy at 5 mills. It sits in Westside #40, whose 42 mill school levy is the second highest touching Johnson County. Take away the school district and Coal Hill would be unremarkable; add it back and Coal Hill becomes the most expensive address in the county.

Hartman

Hartman shares the Westside #40 district with Coal Hill but levies 4.7 mill city tax instead of 5, which produces 57.0 mills. The 0.3 mill gap between the two towns is the smallest rate difference in the county and comes entirely from the city levy.

Lamar and Knoxville

Lamar and Knoxville both sit in the Lamar #39 district and both levy 5 mill city tax, so both land on 55.28 mills, a 4.6 mill gap above Clarksville. Lamar gives its name to the district and Knoxville shares the district and the rate.

Pleasant rural tiers

The cheapest addresses in Johnson County are all rural. Deer/Mount Judea #2 leads at 43.3 mills, followed by Jasper #1 at 47.1, Ozark #14 at 48.8, Clarksville #17 at 49.6 and Lamar #39 at 50.28. Rural parcels pay the 10.3 mill county rate and no city tax.

Dover and Westside rural

The two most expensive rural tiers belong to districts that fringe in from neighbouring counties: Dover #17 at 53.8 mills from Pope County and Westside #40 at 52.3. A rural Johnson County address inside either pays more than a Clarksville city address in the Clarksville #17 district.

Johnson County Assessor

Official name: Johnson County Assessor's Office. The assessor is elected to a four-year term and is required by the Arkansas Constitution to list and value all property subject to ad valorem taxation on an assessment roll each year. The office also maintains parcel records, handles exemptions and administers the homestead credit.

Johnson County's assessor page states the assessment ratio for each property class directly: land is assessed at 20% of the value set for crop, pasture and timber by the Assessment Coordination Division, and residential, commercial and personal property are each assessed at 20% of fair market value, with commercial land treated the same as other commercial property.

The assessor's office publishes its deputy staff alongside the assessor, and the county's own services page links a property information service for looking up owners, taxes owed and addresses. That link resolves to the Johnson County GIS parcel viewer, which shows the parcel summary, buildings, land, sales history and a tax collector tab, and it is the county's own named route to property information. The county assessor's page also confirms the office has a dedicated real estate line at the same (479) 754-3863 number.

Johnson County Collector

Official name: Johnson County Collector's Office. Collector Melanie Cowell also serves as county treasurer. The collector is responsible for collecting all property taxes from the first day of March to October 15 in the calendar year after assessment, and the office does not set values.

Johnson County's collector page documents the delinquency route in statutory terms: any real or personal property tax unpaid by October 15 is delinquent and the collector extends a 10% penalty. Before December 1 each year the collector prepares a list of delinquent taxes and delivers it to a legal newspaper for publication. Land on which taxes remain unpaid for one year after the due date is forfeited to the State of Arkansas and certified to the Commissioner of State Lands for collection or sale.

The collector's page also lists the office staff: Charlsie Butler as chief deputy and Liz Jackson as deputy collector. Payment options described by the county are in person at the Clarksville office or by mail to P.O. Box 794. The ARCountyData Johnson County page, which the assessor and collector both sponsor, carries the online payment link under the heading Pay Johnson County Taxes Online, alongside the collector's office details and a parcel count of 21,859.

How to find a Johnson County parcel's exact tax

Johnson County names its own property information service on the county services page, and that link opens the Johnson County GIS parcel viewer rather than a text search. The ARCountyData platform carries the assessor and collector records behind it, and the tax records and payment link sit on the collector's side.

1. Open the Johnson County Property Information service from the county's services page, which loads the county GIS parcel viewer.
2. Find the parcel on the map, then open the parcel summary. It shows total acreage, square footage, bedrooms and bathrooms where recorded, mailing address, neighbourhood and subdivision.
3. Read the Tax District field on that summary. In Johnson County it is the single most important field, because Clarksville addresses can sit in two different districts and the table above spans 14 mills top to bottom.
4. Check the buildings, land and sales panels on the same screen for the assessor's value components and the recorded sale prices that support them.
5. Switch to the tax collector tab inside the viewer for the amount billed, or open the ARCountyData Johnson County page, which sponsors a free tax record and receipt search and carries the online payment link.

Paying Johnson County property taxes

Johnson County's collection window runs from the first day of March to October 15, and October 15 is the last day to pay without a penalty. Payments can be made in person at the collector's office in Clarksville or by mail to P.O. Box 794, Clarksville, AR 72830. The office keeps 8:00 a.m. to 4:30 p.m. weekday hours.

For online payment, the county's own services page and the ARCountyData Johnson County page are the official routes: ARCountyData carries the Pay Johnson County Taxes Online link together with the collector's office details. Johnson County does not publish a card or convenience fee schedule on its collector page, so confirm the processor fee on the payment screen before submitting.

Missing October 15 has a documented chain of consequences in Johnson County. The collector extends a 10% penalty, prepares a delinquent list for publication in a legal newspaper before December 1, and land with taxes unpaid for a year after the due date is forfeited to the state and certified to the Commissioner of State Lands. That last step is where a small unpaid balance turns into a land sale, and it is covered in more detail in the guide to delinquent Arkansas property tax.

Homestead credit in Johnson County

The Arkansas homestead credit is not automatic. You apply through the county assessor's office, which in Johnson County means the office at 108 S. Fulton Street in Clarksville, and the application is needed once per home.

The maximum credit depends on which bill you are paying. A 2026 bill carries up to $600, and from the 2027 tax bills the maximum rises to $675. The calculator above models a 2026 bill and uses $600.

The ARCountyData Johnson County page, sponsored by the county assessor, states four points about the credit that match the state framework: the credit is worth up to $675 a year for a primary residence, homestead assessment increases are limited to 5% a year against 10% for other property, the taxable value can be frozen for owners aged 65 or over or fully disabled, and only one credit is allowed per household. It also notes the freeze does not stop a tax increase if local millage rates rise or substantial improvements are added, which is why a frozen value and a frozen bill are not the same thing. The state rules behind the freeze are explained in the Arkansas senior property tax freeze.

Appealing a Johnson County assessment

Start with the assessor. Arkansas law provides for an informal hearing with the assessor or a representative before any formal petition, and Johnson County's parcel viewer makes that step easier because the tax district, building, land and sales panels are all on one screen, so you can review the county's own record before you call.

If the informal review does not settle it, apply to the Johnson County Board of Equalization. The statewide application deadline is the third Monday in August each year, and the application may be made in person, by letter or by petition. In Arkansas counties the county clerk's office serves as secretary to the equalization board, which makes the clerk's office the filing route.

At the hearing the assessor presents the case for the valuation first, then the owner presents evidence, then the assessor may rebut. Parcel records for comparable properties showing estimated market values and recent sale prices are the strongest evidence, and a recent private appraisal also carries weight. The board then accepts or changes the value and must notify you in writing afterward.

Johnson County has a specific complication worth raising in an appeal: because Clarksville addresses can sit inside either the Clarksville #17 or the Lamar #39 district, a valuation dispute that centres on which district a parcel falls in should be raised with the assessor's office before the hearing, since the district record is what drives the millage rather than the value itself. Johnson County does not publish a board of equalization page with local hearing dates, so no county-specific deadline is quoted here; use the statewide third-Monday-in-August rule and confirm with the county clerk. The route after a board decision is set out in appealing an Arkansas assessment.

Johnson County property tax examples

Each row uses the Johnson County average of 51.87 mills for 2026 collections with one $600 homestead credit applied. Treat them as estimates; your parcel sits in one specific district and city combination.

Calculated at the 51.87 mill Johnson County average for 2026 collections. Each row applies one $600 credit for a qualifying primary residence.

Johnson County median home value and median tax

This block is historical and statistical information kept separate from the calculator. It is useful for comparison and says nothing about an individual parcel.

Johnson County's median home value of $135,300 pairs with a median annual real estate tax of $709, an effective rate near 0.52%. That sits between Franklin and Independence in this batch, which tracks the county average millage of 51.87 sitting between those two as well.

The implied figure is about double the surveyed one. Running $135,300 through the 20% assessment ratio at the 51.87 mill average produces roughly $1,400 before credit, against a surveyed median of $709. Amendment 79 caps on taxable value, the fact that five of the county's thirteen rows are cheaper rural tiers, and homestead credits already applied on many owner-occupied homes all pull the surveyed median below the arithmetic. Use the Census figures for context and the calculator above for planning.

Johnson County property tax questions

• What is the property tax rate in Johnson County Arkansas?+

  The county average is 51.87 mills for 2026 collections, made up of 39.72 school mills, 4.02 city mills and a flat 10.3 mill county levy. Published combinations run from 43.3 mills in the rural Deer/Mount Judea #2 tier to 57.3 mills for a Coal Hill address inside Westside #40.

• Can two Clarksville addresses really have different property tax rates?+

  Yes, and Johnson County is the only county in this batch where that happens. Clarksville spans the Clarksville #17 and Lamar #39 school districts, so a Clarksville address pays either 51.8 or 52.48 mills. The 2.2 mill city levy is identical in both, so the whole difference is the school district.

• How do I look up a Johnson County parcel?+

  Use the Johnson County Property Information service on the county's services page, which opens the county GIS parcel viewer. The parcel summary shows acreage, square footage, mailing address, subdivision and the Tax District field, plus buildings, land and sales panels and a tax collector tab.

• Where do I pay Johnson County property taxes?+

  In person at the Johnson County Collector's Clarksville office or by mail to P.O. Box 794, Clarksville, AR 72830, Monday to Friday 8:00 a.m. to 4:30 p.m. The Pay Johnson County Taxes Online link sits on the ARCountyData Johnson County page, which the assessor and collector sponsor.

• What happens if I do not pay Johnson County taxes by October 15?+

  The collector extends a 10% penalty, then prepares a delinquent list delivered to a legal newspaper for publication before December 1. Land on which taxes remain unpaid for one year after the due date is forfeited to the State of Arkansas and certified to the Commissioner of State Lands.

• How is property assessed in Johnson County?+

  At 20% of value for each class. The assessor's page states that residential, commercial and personal property are all assessed at 20% of fair market value, and that land used for crop, pasture and timber is assessed at 20% of the value set by the Assessment Coordination Division.

• What is the homestead credit worth in Johnson County?+

One credit is allowed per household, and homestead assessment increases are capped at 5% a year against 10% for other property.

• Which Johnson County town has the highest property tax rate?+

  Coal Hill at 57.3 mills, followed by Hartman at 57.0. Both sit in the Westside #40 school district, which levies 42 school mills, and the 0.3 mill gap between them is entirely city levy: 5 mills in Coal Hill against 4.7 in Hartman.
