Morgan County property tax multiplier set at 1, no assessment change needed

Morgan County property owners got a neutral answer from Springfield: the Illinois Department of Revenue set the county’s final property assessment equalization factor at 1.0000 for taxes payable in 2026, so no state correction was needed.

What does a multiplier of 1 mean? It means Morgan County’s assessments were judged to be close enough to the target level that the state did not add an equalization bump or cut. The tentative factor had been 0.9780 when it was announced on Jan. 22, 2026, but that number moved up after the state reviewed the county data. Morgan County’s prior year factor was 0.9829.

Why does that matter to a homeowner in Jacksonville, Meredosia, or anywhere else in the county? Because the multiplier is the tool Illinois uses to keep property assessments uniform across counties, and property tax is the largest single tax in the state and a major source of revenue for local taxing districts. A change in the multiplier can alter how assessed values are carried into the tax bill, even though it does not set the tax rate itself.

How are Morgan County values supposed to work? The county’s 2025 publication materials say real property is valued using sales from 2022, 2023 and 2024, and the assessments are brought to the required three-year median level of 33.33 percent. Farm property is treated differently because it is based on agricultural economic value and is not subject to the state multiplier.

Could the number still have changed? Yes. IDOR says the tentative factor can be adjusted if the County Board of Review makes significant assessment changes or if local officials provide data showing the department’s estimate of the county’s average assessment level was wrong. In this case, the final result stayed at 1.0000.

Where do county property owners go with questions? Morgan County’s publication list names Allen D. Vogt as supervisor of assessments, with the office at 300 West State Street in Jacksonville. For now, the message from the state is simple: Morgan County avoided a special equalization change this year, and the tax conversation shifts back to local levy decisions and individual assessments that still shape what property owners pay.
