How Property Tax Works

Miller County, Arkansas operates under the state's property tax system to fund essential local services including schools, roads, law enforcement, and county operations. Property taxes are calculated based on assessed value multiplied by the applicable tax rate, with assessment occurring annually. The county follows Arkansas state law requiring properties to be assessed at 20% of true market value for residential properties.

The effective property tax rate in Miller County is approximately 1.250% for the 2025 tax year, though actual rates vary significantly by location within the county due to special taxing districts, school districts, and municipal boundaries. Property owners should verify their specific rate with the Miller County Assessor's office, as rates can differ based on school district boundaries, fire districts, and other special assessment areas within the county.

Supplemental Tax Bills

Supplemental taxes in Miller County occur when there are mid-year changes to property ownership, new construction completion, or significant property improvements. These taxes cover the period from when the change occurred until the end of the current tax year. The supplemental tax is calculated by determining the difference between the old and new assessed values, then applying the current tax rate to that difference.

For example, if you complete a $50,000 home addition in July, and it increases your assessed value by $10,000 (20% of market value), you would owe supplemental taxes on that $10,000 increase from July through the remainder of the tax year. At a 1.250% rate, this would result in approximately $62.50 in supplemental taxes for half the year.

Escrow & Property Taxes

Most mortgage lenders in Miller County require property tax escrow accounts, collecting monthly payments along with your mortgage payment to cover annual property taxes. Lenders typically collect 1/12th of your annual tax bill each month, plus a small cushion as allowed by federal law. Your lender will pay the Miller County Collector directly when taxes become due from March 1st to October 15th each year.

Property owners should verify that their lender has current tax information, especially after reassessments or rate changes. If your escrow account has a shortage due to increased taxes, lenders will typically spread the shortage over 12 months in addition to the new higher payment amount. Homeowners can request escrow analyses annually and may be able to eliminate escrow requirements if they meet certain loan-to-value and payment history criteria with their lender.
