Scott County Iowa Property Taxes: The Complete 2026 Guide
Navigating property ownership in Scott County, Iowa requires a clear understanding of local tax assessments, payment deadlines, equalization orders, and available relief programs. Located along the Mississippi River with Davenport and Bettendorf as its major economic hubs, Scott County operates under specific statutory guidelines governed by the Iowa Department of Revenue and the Scott County Treasurer's Office. Property taxes represent the primary funding mechanism for local county services, school districts, city governments, and emergency response agencies. Managing these financial obligations effectively requires homeowners and commercial investors to stay informed on current valuation cycles, assessment practices, and statutory exemptions.
Understanding the Scott County Assessment and Valuation Cycle
Property assessments in Scott County do not occur every single year. Iowa operates on a biennial assessment cycle, meaning real estate valuations are updated in odd-numbered years. The value established as of January 1 of an odd-numbered year typically serves as the basis for property tax calculations across two subsequent fiscal years.
- Assessment Year: Properties are reassessed by the Scott County Assessor's Office (or local city assessors in Davenport and Bettendorf) every odd-numbered year to reflect market conditions.
- Notice of Assessment: Property owners receive assessment notices in the spring of the assessment year if there is a change in the taxable value or classification.
- Equalization: The Director of Revenue reviews local assessments to ensure uniformity across counties, applying state-wide equalization orders if regional discrepancies appear.
- Tax Levy Application: Mill rates (or levy rates) are applied to the taxable value—not the full market value—after accounting for state-mandated assessment limitations such as the residential rollback.
Key Scott County Iowa Property Tax Deadlines for 2026
Staying compliant with tax schedules prevents statutory interest penalties and tax sales. Scott County property taxes are paid a year in arrears, meaning the bills issued in 2026 cover the fiscal period spanning July 1, 2024, through June 30, 2025, or follow the structured split-payment schedule for the current fiscal cycle.
| Installment / Period | Due Date | Delinquency Date | Notes & Penalties |
|---|---|---|---|
| First Half Installment | September 1, 2025 | October 1, 2025 | Becomes delinquent on October 1; accrues 1.5% interest per month. |
| Second Half Installment | March 1, 2026 | April 1, 2026 | Becomes delinquent on April 1; accrues 1.5% interest per month. |
| Full Year Payment Option | September 1, 2025 | October 1, 2025 | Can be paid in full by the first installment deadline without penalty. |
| Tax Sale Listing | Varies (June 2026) | June 30, 2026 | Unpaid prior-year taxes are subject to the annual Scott County tax sale. |
Failure to meet these payment thresholds triggers a statutory interest penalty of 1.5% per month, rounded to the nearest whole dollar. Property owners must ensure payments are postmarked or processed electronically by the close of business on the delinquency date to avoid compounding fees.

Calculating Your Scott County Property Tax Bill
Computing your exact tax obligation involves a multi-step formula that incorporates market valuation, the state rollback percentage, taxable value, and the consolidated local levy rate.
Important Calculation Formula: Market Value × State Rollback Percentage = Assessed Taxable Value (Taxable Value ÷ 1,000) × Consolidated Levy Rate = Gross Tax Liability Before Credits
The Residential Rollback Factor
The Iowa legislature implements a assessment limitation formula—commonly called the rollback—to curb dramatic spikes in residential property taxes. If residential property values statewide grow faster than a statutory cap (typically 3%), the state applies a rollback factor to reduce the portion of the value subject to taxation.
Consolidated Tax Levy Rates
Different taxing authorities overlay your specific property parcel. A home located within the Davenport city limits supports the city government, the Davenport Community School District, Scott County, Eastern Iowa Community College, and regional assessor funds. Each entity adopts a separate dollar-per-thousand levy rate. When combined, these rates form the consolidated mill levy utilized on your annual statement from the Scott County Treasurer.
Available Property Tax Exemptions and Relief Programs in Iowa
Property owners in Scott County can significantly reduce their tax liabilities by utilizing state-sanctioned credits and exemptions. These programs target specific demographics, including military veterans, agricultural operators, homestead occupants, and low-income elderly or disabled residents.
- Homestead Tax Credit: Available to homeowners who occupy their property as their primary residence on or before July 1 of the assessment year. It exempts a portion of the home's value from taxation.
- Military Service Tax Exemption: Provides a property tax reduction for qualifying veterans who served during designated periods of conflict, with enhanced benefits for disabled veterans.
- Disabled Veteran Homestead Tax Credit: Offers a near-total or complete property tax exemption on the homestead property for qualifying veterans with a 100% permanent service-connected disability rating.
- Elderly and Disabled Property Tax Credit / Rent Reimbursement: State-funded program providing relief for homeowners aged 65 or older, or total-disabled individuals meeting specific household income thresholds.
- Business Property Tax Credit: Reduces the taxable value of commercial, industrial, and railroad properties through state-funded property tax replacement credits.
How to Appeal Your Property Assessment in Scott County
If you believe the assessed value assigned to your property by the Scott County Assessor exceeds fair market value or is inequitable compared to similar neighboring properties, you have the legal right to appeal. The appeal process requires strict adherence to statutory filing windows.
- Informal Review: Contact the Scott County Assessor's Office (or the local city assessor for Davenport or Bettendorf) during the informal review window, which runs from April 2 through April 25 of the assessment year. Present comparable sales data, recent appraisal documents, or photographic proof of structural damage.
- Local Board of Review: If the informal review does not yield a satisfactory adjustment, file a formal petition with the Scott County Board of Review between April 2 and May 5. The Board holds formal hearings through the month of May.
- Property Assessment Appeal Board (PAAB) or District Court: If the Board of Review denies your petition or grants an insufficient adjustment, you can appeal further to the state-level Property Assessment Appeal Board or the Scott County District Court within 20 days of the Board's decision.
