How Property Tax Works

Johnson County, Nebraska operates on a property tax system that funds essential local services including schools, county government operations, emergency services, and infrastructure maintenance. Property taxes are assessed annually based on market value and levied as of November 1, becoming a lien on the property at that date. The tax year runs from January 1 to December 31, with taxes due by December 31 of each year.

The effective tax rate in Johnson County for the 2025 levy year was 1.2176%, down from 1.3217% in 2024. However, actual tax rates vary significantly by location within the county due to different combinations of special taxing districts, including school districts, fire districts, natural resource districts, and municipal improvement districts. Property owners may see rates ranging from approximately 0.9% to 1.4% depending on their specific location and the overlay of various taxing jurisdictions that serve their property.

Supplemental Tax Bills

Supplemental taxes in Johnson County are triggered by changes in property ownership, new construction, or improvements that increase a property's assessed value during the tax year. When these events occur after the annual assessment date of January 1, the County Assessor may issue a supplemental assessment to capture the additional taxable value.

Supplemental taxes are calculated by applying the current year's tax rate to the difference between the new assessed value and the previous assessed value, prorated for the portion of the tax year remaining. For example, if a $100,000 home addition is completed in July, creating $100,000 in additional assessed value, the supplemental tax would be calculated as: $100,000 × 1.2176% × 6/12 months = approximately $609 for the remaining six months of the tax year.

Example Calculation

Example 1: $300,000 Home

  • Market Value: $300,000
  • Assessed Value (100%): $300,000

  • Assessed Value (100%): $600,000
  • Less: Homestead Tax Credit (if applied): -$40,000 max
  • Net Taxable Value: $560,000
  • Annual Tax: $560,000 × 1.2176% = $6,819
  • Monthly Escrow: $568

Example 3: $1,000,000 Home

  • Market Value: $1,000,000
  • Assessed Value (100%): $1,000,000
  • Less: Homestead Tax Credit (if applied): -$40,000 max
  • Net Taxable Value: $960,000

Section 5

Escrow & Property Taxes

Most mortgage lenders in Johnson County require property tax escrow accounts for loans with less than 20% down payment. Lenders collect monthly escrow payments equal to 1/12 of the annual property tax bill, plus insurance premiums. These funds are held in a separate account and used to pay property taxes when due on December 31.

Lenders typically conduct annual escrow analyses to ensure adequate funds are collected. If property taxes increase, monthly escrow payments may be adjusted upward, sometimes requiring a one-time shortage payment. Property owners should receive an annual escrow statement showing all deposits, payments, and account balance. The first half of property taxes becomes delinquent on May 1 of the following year if unpaid, so lenders usually remit payment in December to avoid penalties. Property owners can verify their tax payments through the Johnson County Treasurer's office or online portal.

Frequently Asked Questions

Q: When are property taxes due in Johnson County for the current tax year? A: Property taxes are due December 31 for the 2025 tax year. The first half becomes delinquent on May 1, 2026, and the second half becomes delinquent later in the year if unpaid.

Q: What homestead tax credits are available and how do I apply? A: Johnson County offers homestead tax credits for qualifying homeowners age 65+ (up to $40,000 reduction in taxable value) and disabled veterans. These are credits that reduce your tax bill and require annual application to the County Assessor's office. Applications are typically due by June 30.

Q: Does the homestead credit reduce my home's market value? A: No, the homestead credit is a tax credit that reduces your taxable value for tax calculation purposes only. It does not affect your property's assessed or market value, and it caps assessment increases rather than reducing the underlying valuation.

Q: How often are properties reassessed in Johnson County? A: Nebraska law requires properties to be assessed annually at 100% of market value as of January 1. The County Assessor reviews market data and may adjust individual property values based on sales, improvements, or market conditions.

Q: How do I appeal my property assessment? A: File a protest with the Johnson County Board of Equalization between May 1 and June 30. You must provide evidence supporting your claim that the assessed value exceeds market value, such as comparable sales or professional appraisals.

Q: What are the penalties for late property tax payments? A: Interest and penalties accrue on delinquent taxes. The first half becomes delinquent May 1 with interest charges applied. If taxes remain unpaid for three years, the property may be subject to tax sale proceedings.

Q: Can I pay my property taxes online? A: Yes, Johnson County typically offers online payment options through the County Treasurer's website. Payment methods usually include electronic check and credit card options, though convenience fees may apply for credit card payments.

Q: Why did my property taxes increase if I didn't improve my property? A: Property taxes can increase due to rising property values, increased tax rates from local taxing districts (schools, fire districts, etc.), or voter-approved bond issues. Even without improvements, your property value may rise due to market conditions.

Q: How do special taxing districts affect my property tax bill? A: Your property tax rate is a combination of all taxing districts that serve your property, including county, school district, city (if applicable), fire district, and others. Different areas of Johnson County have different combinations of these districts, causing tax rate variations across the county.

Q: What documentation do I need to apply for property tax credits? A: Documentation varies by credit type but typically includes proof of age (for senior credits), disability verification (for disabled credits), income statements, and proof of primary residence. Contact the Johnson County Assessor's office for specific requirements and application forms.
