| Rock City | 2.60% | Rock City area schools, Stephenson County |
| Freeport (city) | Varies by parcel | Freeport School District, City of Freeport, Park District |

Agricultural Land Assessment in Stephenson County
Agricultural parcels in Illinois receive a special assessment based on productivity rather than market value. The Stephenson County Assessment Office applies the Illinois Farmland Assessment Law to every qualifying farm parcel.
Farmland Valuation Rules
- Soil productivity index determines the per-acre certified value
- Cropland, pasture, and timber each receive a separate value category
- Five-year equalized assessed value averages smooth market swings
- Farm buildings are valued separately using depreciation schedules
- Farmland must stay in agricultural use to keep the special classification
Commercial Property Assessment
Commercial properties follow a separate valuation method that includes income, expense, and market data. The Chief County Assessment Office reviews income-producing parcels every year to reflect current rents and operating costs.
How Commercial Properties Are Assessed
- Three standard approaches include cost, sales comparison, and income capitalization
- Income capitalization applies a cap rate derived from local market data
- Operating expenses such as property management and repairs are subtracted from gross income
- Vacancy and credit loss factors reduce the effective rental stream
- Replacement cost new minus depreciation supports the cost approach
School District Levy and Local Taxing Bodies
School district levies represent a large share of every property tax bill in Stephenson County. Voters in each district can shape future levies through ballot referenda and public budget hearings.
How Levies Affect Tax Bills
- School boards adopt the levy each year during scheduled board meetings
- County Clerk extends the levy across the district’s equalized assessed value
- PTELL caps most districts’ annual levy growth at 5% or the rate of inflation
- Bond and interest levies may bypass PTELL with voter approval
- Special education and transportation costs appear as separate line items

Mortgage Escrow and Property Tax
Many homeowners pay property taxes through a mortgage escrow account managed by their loan servicer. The servicer collects monthly tax payments, holds the funds, and pays the Treasurer on the homeowner’s behalf.
How Escrow Accounts Work
- Loan servicer divides the annual tax bill into 12 monthly payments
- Servicer pays the Treasurer when each installment becomes due
- Annual escrow analysis checks that the collected amount matches the actual bill
- Surplus funds may be refunded or applied to the next year’s escrow
- Shortfalls often result in a higher monthly payment for the following year
Stephenson County Treasurer’s Office
The Treasurer’s office issues tax bills, processes payments, and publishes the annual delinquent list. Treasurer Stephanie Helms announced that the 2026 tax year bills were mailed on May 20, with online bill viewing, printing, and payment available starting May 26.
