# DeKalb County Announces 2026 Property Assessment Multiplier

DeKalb County, Illinois, has set its tentative property assessment equalization factor (multiplier) at 1.0000 for the 2026 tax year payable in 2027. This multiplier indicates that property assessments are aligned with one-third of market value, ensuring uniformity in property valuation across the county. While this factor standardizes assessments, the ultimate tax bills will depend on the budget requests of local taxing authorities. Procurement professionals and contractors involved in property valuation, tax consulting, and local government services should note this update as it affects property tax calculations and related financial planning for the upcoming fiscal year.

- The Illinois Department of Revenue and DeKalb County Board of Review oversee and implement the assessment multiplier, impacting local tax administration.
- Uniform assessment factors can influence budgeting and procurement decisions for county services related to property tax collection and appeals.
- Contractors providing property assessment, appraisal, or tax consulting services may find opportunities aligned with the updated multiplier and local government fiscal planning.
- Stakeholders should consider how this multiplier affects contract scopes and pricing models tied to property tax revenues and assessments.
