Property Tax in Cole County, 2026

A calculator and field guide for Jefferson City-area homeowners — and for anyone considering a move to Cole County — including Missouri's 19% residential assessment ratio (constitutionally fixed), Senate Bill 190's senior property tax freeze (age 62+, county opt-in — adopted by ~85 of 114 MO counties), the Missouri Property Tax Credit Claim (refundable up to $1,100), and triennial reassessment (every odd-numbered year).

Cole County, home to Jefferson City and 77k Missourians, operates under Missouri's constitutionally-fixed property tax system. Residential property is assessed at 19% of fair market value (Mo. Const. Art. X §4(b)); tax = AV × consolidated rate per $100. Reassessments occur every odd-numbered year. Senate Bill 190 (2023) authorizes counties to enact a senior property tax freeze for owners 62+ — and Cole County has adopted this freeze.

How the bill is built

Missouri property tax follows a 3-step calculation. Step 1: Fair Market Value. The Cole County Assessor determines FMV every odd-numbered year. Step 2: Apply 19% residential assessment ratio. AV = FMV × 19%. Commercial uses 32%; agricultural uses 12%. Step 3: Apply consolidated rate. Tax = AV × consolidated rate ÷ $100. Cole's combined consolidated rate is approximately $5.58/$100 of AV — the effective rate against market value works out to about 0.94%.

SB 190 Senior Property Tax Freeze (county opt-in, age 62+). Missouri's primary senior protection — locks the property tax bill at the year-of-eligibility level. Approximately 85 of Missouri's 114 counties + St. Louis City have adopted SB 190 (including all major metros: St. Louis, Jackson, Clay, Platte, St. Charles, Greene, Boone, Jefferson, Cass). The base year is the year the senior turned 62 AND submitted an application. Future increases (voter-approved bonds, new construction/improvements, Missouri Blind Pension Fund) can still raise the bill. Apply with your county collector / assessor — applications typically open December - March each year.

Missouri does NOT provide a full property tax exemption for 100% disabled veterans — unusual among states. The primary veteran property tax relief is the Missouri Property Tax Credit Claim (MO-PTC), a refundable credit up to $1,100/year (income-tested at $30,000-$34,000). Available to 100% disabled vets, surviving spouses, AND seniors 65+. File Form MO-PTC with your Missouri state income tax return by April 15. Disabled veterans 62+ should file BOTH MO-PTC AND apply for the SB 190 senior freeze if their county has adopted.

Reassessments occur every odd-numbered year — and have produced significant volatility. Missouri's 2023 reassessment cycle produced 30%+ valuation increases in some counties (most-publicized: Jackson County's reassessment, which led to legal challenges). Property owners can appeal to the County Board of Equalization within 30 days of receiving the change of value notice — appeals must include comparable sales evidence, recent appraisals, or condition documentation.

2026 Cole County rate breakdown (consolidated rate per $100 of AV (19% of market value), Jefferson City district)

Taxing entity	Rate

As of April 29, 2026 · From Cole County Assessor.

Note: Cole County is home to Jefferson City, Missouri's state capital and one of only four US state capitals not served by an Interstate highway (along with Pierre SD, Dover DE, and Juneau AK). Major employers include the State of Missouri (~15,000 state workers in Jefferson City), Capital Region Medical Center, SSM Health St. Mary's Hospital, Scholastic Inc. (large book distribution center), and ABB Power Electronics. The Missouri State Penitentiary (operational 1836-2004, now a museum) was once the largest prison in the United States.

Note: Cole County's combined mill rate runs ~$5.58 per $100 of assessed value in Jefferson City — but Missouri assesses residential property at only 19% of true market value, so the effective rate on full market value runs around 0.94%. Missouri's 19% residential AR (vs 12% agricultural, 32% commercial) is among the more taxpayer-friendly residential ratios in the US. The substantial state government tax-exempt property is partially offset by Payments in Lieu of Taxes (PILT).

Note: Missouri's graduated income tax tops out at 4.7% (2026) and offers a $1,100 Senior Citizen Property Tax Credit (income-tested for 65+ with HHI ≤ ~$30K). Cole County's substantial state-employee retiree population uses the credit widely. The substantial Lewis & Clark Trail tourism (Jefferson City sits on the Missouri River) and Capitol Building tours drive secondary economic activity.

Deductions and exemptions for 2026

Missouri homeowner property tax relief operates differently than most states. The structural protection is the 19% residential assessment ratio — applied automatically (no application needed). Senior homeowners 62+ should focus on the SB 190 Senior Property Tax Freeze (county opt-in). 100% disabled veterans receive ONLY the partial Missouri Property Tax Credit Claim (MO-PTC) — Missouri does NOT provide a full vet exemption.

The 19% Residential Assessment Ratio (constitutional)

Missouri Constitution Art. X §4(b) fixes residential property at 19% of fair market value for assessment purposes. Commercial property uses 32%; agricultural property uses 12%. This is the structural protection — applied automatically with no application. The constitutional ratio means a home with $300K market value has only $57K assessed value (compared to states with 100% AR where the same home would have $300K AV against the rate).

SB 190 Senior Property Tax Freeze (county opt-in)

Missouri Senate Bill 190 (2023, modified 2024-2025) allows counties to enact a senior property tax freeze. Cole County HAS adopted SB 190. Eligibility: age 62+ as of December 31 of the application year; primary residence in Cole County; owner of record (or trust grantor); responsible for property taxes. Mechanism: base year is the year you became eligible AND submitted an application; bill is locked at the base-year amount. Exceptions (still increase): voter-approved bond indebtedness, new construction or improvements, Missouri Blind Pension Fund. Application: file with the county collector / assessor; application periods typically open December - March each year.

Missouri Property Tax Credit Claim (MO-PTC, refundable)

The MO-PTC provides a refundable credit up to $1,100/year for qualifying owners (or $750 for renters). Eligibility: seniors 65+, 100% disabled veterans (service-connected), surviving spouses of disabled vets, or 100% disabled non-vet. Income limits: $30,000 single / $34,000 married filing jointly for owners (lower for renters). File Form MO-PTC with your Missouri state income tax return by April 15. The credit is refundable — meaning you receive it even if you have no income tax liability. Disabled veterans 62+ should file BOTH MO-PTC AND apply for the SB 190 senior freeze.

Appealing your assessment

Missouri property tax appeals follow a 3-tier process. Level 1: County Board of Equalization (BOE). File a written appeal within 30 days of receiving the change of value notice (notices typically mailed late June - early July in reassessment years, which are odd-numbered). The BOE holds informal hearings — homeowners present comparable sales, recent appraisals, or condition documentation. Level 2: State Tax Commission. If denied, appeal to the State Tax Commission of Missouri within 30 days of the BOE decision. The STC is a quasi-judicial state agency that holds formal evidentiary hearings. Level 3: Circuit Court. STC decisions can be appealed to the county Circuit Court on legal/constitutional grounds. Most Missouri appeals are resolved at Level 1.

Frequently asked questions

When are Missouri property taxes due?

Missouri property taxes are due December 31 of the tax year. Cole County bills are typically mailed in November. Late payments accrue interest plus penalty (typically 9% annual interest plus monthly penalty). Most Missouri homeowners pay through escrow via mortgage servicer. Some counties offer optional installment plans — contact your county collector for current options.

What is the SB 190 Senior Property Tax Freeze?

Missouri Senate Bill 190 (2023, modified 2024 and 2025) authorizes counties to enact a senior property tax freeze for owners 62 or older. The freeze locks the property tax bill at the year-of-eligibility level. Cole County HAS adopted SB 190. Eligibility: 62+ as of December 31; primary residence in the county; owner of record (or trust grantor); responsible for property taxes. Exceptions still increase: voter-approved bond indebtedness, new construction or improvements, Missouri Blind Pension Fund. Approximately 85 of Missouri's 114 counties + St. Louis City have adopted SB 190 — including all major metros.

How do I apply for the SB 190 senior freeze in Cole County?

Apply with your county collector / assessor. Application periods vary by county but typically run December - March each year. Required documents typically include: (a) proof of age (driver's license, birth certificate, or other government ID); (b) proof of ownership (deed, trust documents); (c) proof of primary residence (Missouri driver's license with property address; voter registration); (d) prior year's tax bill (establishes base year). The base year is the year you became eligible AND submitted an application. Annual renewal is typically required — file each year by the county's deadline.

Does Missouri have a full property tax exemption for 100% disabled veterans?

No — Missouri does NOT provide a full property tax exemption for 100% disabled veterans. This is unusual among states (most states offer some form of full disabled vet exemption). Missouri's primary veteran property tax relief is the Missouri Property Tax Credit Claim (MO-PTC): a refundable credit up to $1,100/year (income-tested at $30,000-$34,000 depending on filing status). Available to 100% disabled vets, surviving spouses, and seniors 65+. File Form MO-PTC with your Missouri state income tax return by April 15. Missouri's lower aggregate cost of living and SB 190 senior freeze partially offset the lack of full vet exemption — but disabled vets seeking full exemption may want to compare other states (Maryland, Virginia, Iowa, Wisconsin, Pennsylvania, etc.).

How does Missouri's reassessment cycle work?

Missouri reassesses real property every odd-numbered year (the "biennial" reassessment cycle, though "biennial" technically means every 2 years). Reassessments occurred in 2021, 2023, and 2025; the next is 2027. The 2023 cycle produced significant volatility — Jackson County's reassessment showed 30%+ valuation increases in some areas, leading to legal challenges and ongoing political fallout. Property owners can appeal to the County Board of Equalization within 30 days of receiving the change of value notice. Comparable sales evidence is the most-effective basis for appeal.

How do I appeal my Missouri assessment?

Missouri property tax appeals follow a 3-tier process. Level 1: County Board of Equalization (BOE). File appeal within 30 days of receiving the change of value notice (mailed late June - early July in reassessment years). BOE holds informal hearings — present comparable sales, recent appraisals, or condition documentation. Level 2: State Tax Commission of Missouri (STC). If denied, appeal to STC within 30 days of BOE decision. STC is a quasi-judicial state agency that holds formal evidentiary hearings. Level 3: Circuit Court. STC decisions can be appealed on legal/constitutional grounds. Most appeals are resolved at Level 1 — BOE members are often local citizens familiar with neighborhood values.

About Cole County

Beyond the property tax — a few things you might not know about the place.

Weird fact

The Missouri State Capitol building in Jefferson City is the third capitol on the same site — the first burned down in 1837, the second burned down in 1911 (struck by lightning), and the current building (completed in 1917) is built of Carthage limestone with marble interiors. The dome murals were painted by NC Wyeth and Frank Brangwyn; the Thomas Hart Benton mural cycle "A Social History of the State of Missouri" (1936) in the House Lounge is among the most important examples of American Regionalism mural painting.

Hometown hero

Thomas Hart Benton

American Regionalist painter (1889-1975), one of the most prominent muralists of the 20th century. Painted the celebrated "A Social History of the State of Missouri" (1936) in the Missouri State Capitol House Lounge — a controversial work depicting Jesse James, Frankie & Johnny, slavery, and Boss Tom Pendergast. Benton's depiction of Missouri history was controversial enough to spawn sustained protests when unveiled.

Biggest annual event
