Property Tax on Lake Ouachita: Garland and Montgomery County

Arkansas Property Tax Basics

Arkansas assesses all real property at 20% of market value statewide -- one of the most buyer-friendly assessment ratios in the country. That means a $300,000 cabin has an assessed value of $60,000 for tax purposes. The annual tax bill is calculated by multiplying the assessed value by the local millage rate (expressed in mills, where one mill equals $1 per $1,000 of assessed value). A $60,000 assessed value at 30 mills produces a $1,800 annual tax bill. At 35 mills it produces $2,100. The formula never changes regardless of county.

A $375 homestead credit (raised to $425 as of 2024 per some sources -- verify with the county assessor) applies to primary residences. Senior homeowners aged 65 and older with income below the state-set threshold can apply for the Arkansas senior property tax freeze, which locks the assessed value in perpetuity for the life of their ownership. This is among the most powerful senior tax benefits in the country and is available in both Garland and Montgomery counties upon application at the respective assessor's office.

Garland County: The Eastern Lake and Mountain Pine Area

Garland County covers the eastern portion of Lake Ouachita near Blakely Mountain Dam, the Mountain Pine community, and Lake Ouachita State Park. Garland County is also the county that contains Hot Springs, which means it carries more property tax activity and better-resourced county services than Montgomery County.

Garland County's effective property tax rate is approximately 0.44% of market value -- well below the Arkansas median of approximately 0.52% and the national median of 1.02%. SmartAsset reports the median annual tax payment in Garland County at roughly $985 on a median home value of $224,200. For a $300,000 cabin in Garland County: assessed value $60,000; at the county's approximate effective millage range of 30--38 mills depending on the specific school district (Mountain Pine School District vs. Hot Springs School District rates differ): annual tax approximately $1,800 to $2,280.

Lake Ouachita State Park is located in Garland County near Mountain Pine, and the Mountain Pine School District covers this area. Buyers whose property search extends to the Garland County portion of the lake should verify the precise school district at their specific address, as district boundaries do not follow obvious geographic lines in this area.

Montgomery County: The Main Lake Body

Montgomery County holds the majority of Lake Ouachita's surface area and most of its resort communities, including Mountain Harbor, Brady Mountain, Echo Canyon, and the majority of Highway 27 Fishing Village. Mount Ida is the county seat with approximately 800 to 900 residents -- a genuinely small rural county with a correspondingly modest tax base and low millage rates.

Montgomery County's effective property tax rate is among the lowest in Arkansas. With a median home value substantially lower than the state median and a rural county tax base that does not require high millage rates to fund county services, the effective rate runs in the 0.35% to 0.45% range. The Mount Ida School District is the primary school district covering most resort community addresses in Montgomery County.

For a $300,000 cabin in Montgomery County: assessed value $60,000; at approximately 28 to 32 mills: annual tax approximately $1,680 to $1,920. These are among the lowest annual tax bills available on any Arkansas lake property at this price point. The trade-off is that county services reflect the tax base -- road maintenance, emergency response times, and public infrastructure in rural Montgomery County reflect a county that is sparsely populated and has limited revenue relative to Garland or Benton counties.

What Property Tax Does Not Capture

The property tax bill is the easiest number to find and the easiest to compare across properties. On Lake Ouachita, it is frequently the smallest of the annual recurring costs. Resort HOA or membership fees, marina slip rental, and land lease payments (in applicable communities) can together exceed the annual tax bill in some resort structures.

A $300,000 cabin with a $1,800 annual property tax bill might also carry $1,500 in resort membership fees, $2,000 in marina slip rental, and $800 in land lease payments -- a total non-mortgage recurring cost burden of $6,100 per year before insurance and utilities. A comparable property at Greers Ferry Lake with a higher tax bill ($2,500 to $3,200 annually) but no resort fees, no slip rental beyond a dock on private land, and no land lease might actually carry lower total annual costs. Comparing only property tax rates between the two lakes produces a misleading result.

The Land Lease Tax Question

In resort communities where buyers own a structure but not the underlying land -- leasing the land from the resort operator or under a USACE concession framework -- the property tax assessment applies only to the structure value, not to the land. This can produce a lower assessed value than a fee-simple purchase of equivalent market price would generate. However, the land lease payment itself is not tax-deductible as a property tax equivalent in most cases -- it is a lease payment, not a tax, and should be evaluated accordingly in the total cost analysis.

If you are purchasing within a land-lease community, ask the current owner to provide three years of property tax bills, resort fee invoices, and land lease payment history. This gives you an accurate picture of the recurring annual cost burden from documented actual payments rather than from estimates that may not account for fee increases, lease renegotiations, or assessment adjustments.

Applying for the Senior Freeze

For buyers aged 65 and older with qualifying income, the Arkansas senior property tax freeze is a meaningful benefit at Lake Ouachita specifically because resort community property values in this market tend to be stable rather than rapidly appreciating -- the freeze locks in an already-favorable assessment. Applications are filed with the Montgomery County Assessor's office (Mount Ida) or the Garland County Assessor's office (Hot Springs) depending on which county the property falls in. The freeze applies only to a primary residence -- vacation properties and rental properties do not qualify. Once established, it survives the life of the owner's tenure without annual renewal as long as the property remains their primary residence.
