How Property Tax Works

Marshall County's property tax system serves as the primary funding mechanism for essential local services including public schools, county operations, emergency services, and infrastructure maintenance. Property owners pay taxes based on their property's assessed value multiplied by the applicable tax rate, which varies significantly depending on location within the county due to different combinations of special taxing districts.

The effective tax rate in Marshall County typically ranges from approximately 0.8% to 1.2% of assessed value, though this can vary based on your specific location and the special districts that serve your property. Marshall County assesses property at its fair cash value, and taxes are calculated on a split-payment schedule with the first half due September 1st and the second half due March 1st of the following year. It's important to note that actual rates vary considerably by location within the county due to overlapping school districts, municipal boundaries, and other special taxing jurisdictions.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Marshall County are additional property tax bills issued when there are mid-year changes to property ownership, value, or exemption status. The most common triggers include new construction completion, change of ownership that removes previous exemptions, or corrections to assessment errors discovered after the regular tax roll is finalized.

When supplemental taxes are levied, they are calculated from the effective date of the change through the end of the current tax year. For example, if new construction is completed and gains a certificate of occupancy in January, supplemental taxes would be calculated for the remaining months of that tax year. The supplemental bill is typically issued within 30-60 days of the triggering event and follows the same payment schedule as regular property taxes, with applicable penalty dates adjusted accordingly.

Escrow & Property Taxes

Most mortgage lenders in Marshall County require property tax escrow accounts, where monthly mortgage payments include a portion designated for property taxes. Lenders collect approximately 1/12th of the annual tax bill each month and pay the taxes directly to Marshall County when due. The escrow account is typically established at closing with an initial deposit covering several months of taxes.

Lenders perform annual escrow analyses to ensure adequate funds are collected, and may adjust monthly payments if tax amounts change significantly. Property owners should verify that their lender pays both the September 1st first half payment and March 1st second half payment on time, as the property owner remains ultimately responsible for timely payment even when using escrow. If you pay taxes directly without escrow, remember that the first half becomes delinquent after September 1st, and the second half becomes delinquent after March 1st of the following year.

All credits require formal application through the County Assessor's office and are not automatically applied. Applications must typically be filed by March 15th to be effective for the current tax year.

Q: How does the Homestead Credit work? A: The Homestead Credit provides a $1,000 credit against your tax bill and caps assessment increases on your primary residence.

Q: How often is property reassessed in Marshall County? A: Oklahoma law requires properties to be reassessed periodically, though the specific cycle varies. The County Assessor's office conducts ongoing reassessments and updates values based on market conditions, sales data, and property improvements.

Q: What are the penalties for late payment? A: Property taxes not paid by their due dates are subject to penalties and interest. The first half becomes delinquent after September 1st, and the second half after March 1st. Delinquent taxes may eventually result in tax lien sales.
