Did your new assessment land in the mail and leave you wondering what changed? If you live in Papillion, La Vista, Ralston, or greater Omaha, you’re not alone. Understanding how values are set in Sarpy and Douglas counties can help you plan for taxes, escrow, and any selling decisions this year. In this guide, you’ll learn how Nebraska assessors determine value, the key timing and appeal steps for each county, and what to do if you disagree with your assessment. Let’s dive in.
How Nebraska sets assessed values
Nebraska counties follow a state-regulated system designed to estimate a property’s market, or actual, value for taxation. County assessors use mass appraisal to keep valuations consistent across thousands of parcels. While your property is unique, the county’s goal is uniformity that reflects the market as of a fixed valuation date, typically around the start of the year. Always verify the current valuation date on your county assessor’s site or by phone.
Assessors rely on three main approaches and choose what best fits your property:
- Sales comparison: Most common for homes. Recent sales of similar properties in your area guide value.
- Cost approach: Replacement cost new, minus depreciation, plus land value. Often used for newer or unique homes.
- Income approach: Used for income-producing property. Rents, expenses, and investor returns determine value.
To keep values up to date, assessors study deeds and sales, building permits, inspection notes, MLS data, GIS maps, aerial imagery, and cost guides. They also apply time adjustments and neighborhood models to reflect broader trends. Mass appraisal can’t capture every remodeling detail or on-trend upgrade right away, which is why your assessed value may not match a private appraisal.
Assessed vs. taxable vs. market value
- Market (actual) value is the price a home would likely bring in an arms-length sale.
- Assessed value in Nebraska is intended to reflect market value for assessment purposes.
- Taxable value is your assessed value minus any exemptions or special classifications.
Sarpy vs. Douglas: what’s the same
Sarpy County and Douglas County operate under the same statewide rules. Both:
- Produce annual assessment rolls and mail valuation notices to property owners.
- Update values with recent market sales and property data.
- Provide informal and formal protest processes at the county level, with options to appeal to the Nebraska Tax Equalization and Review Commission (TERC).
Sarpy vs. Douglas: key differences to expect
While the framework is the same, you may see practical differences:
- Market dynamics: Sarpy County, including Papillion and La Vista, often experiences rapid growth and new construction, which can drive more parcel-level adjustments. Douglas County, including Omaha and Ralston, manages a larger and more diverse housing stock, which can make neighborhood modeling more complex.
- Data volume and resources: A larger parcel base in Douglas can affect inspection schedules, update speed, and how often neighborhoods are revalued.
- Timing and procedures: Mailing schedules and protest windows can differ by county each year. Do not rely on last year’s dates. Check your county assessor’s current notices and instructions.
The typical timeline to expect
Valuation date and notices
Counties measure market conditions as of a fixed valuation date for each tax year. They then mail valuation notices in a defined window, typically in the spring. Your notice lists the new value and explains how to request a review or file a protest. Because dates change, check your county assessor’s website or call the office to confirm the current year’s schedule.
Protest windows and appeals
After notices go out, you have a limited protest period. Many owners start with an informal conversation to correct data errors. If you still disagree, you can file a formal protest for a hearing with the county’s board. If you remain dissatisfied after the county decision, you can explore an appeal to the state-level TERC. Each step has strict deadlines. Verify the current year’s procedures with your county and the state.
How assessments affect taxes and escrow
Your property tax bill is generally your taxable assessed value multiplied by the combined levy rate set by local taxing authorities. When assessed value rises and levy rates stay the same, your tax bill typically goes up.
If you have a mortgage escrow, your lender estimates taxes and adjusts your monthly payment during the annual escrow analysis. A higher assessment can lead to a higher monthly escrow amount.
- Simple example: If your annual tax bill increases by 1,200 dollars, your monthly escrow portion would rise by about 100 dollars. Your servicer may also require a catch-up payment if the current escrow balance is short.
Timing matters. An assessment change can affect the next annual tax bill. If you sell partway through the year, taxes are often prorated at closing based on last year’s bill or an estimate for the current year, depending on local practice.
Selling soon? What assessed value really means
County values are mass appraisals, while a lender’s appraisal is a single-property analysis tied to your contract and the most comparable recent sales. That difference can create gaps between your assessed value and your sale price.
- For sellers: A higher assessed value can suggest more equity, but your final sale price will depend on current buyer demand and appraisal-supported comps. A lower assessed value does not prevent you from selling for more if the market supports it.
- For buyers: Public records can inform expectations, but appraisals and recent sales drive lending decisions.
New construction and major remodels often trigger reassessment once permits hit the system or the assessor updates records. Improvements that help your sale may not immediately appear in the county roll.
What to do when your notice arrives
Act quickly when you receive your valuation notice. Deadlines are firm.
- Review your property record card for accuracy, including square footage, bed/bath count, lot size, year built, and any recorded improvements.
- Compare the county’s neighborhood grouping or model with recent local sales of homes in similar condition.
- Keep notes on any features that affect value, such as needed repairs or location factors.
If you disagree: how to protest
Start simple, then escalate if needed.
- Informal contact: Call or email the assessor’s office to verify data and request an informal review. Many issues are resolved here.
- Gather evidence: Pull recent comparable closed sales, photos showing condition, contractor estimates for repairs, any private appraisal, and permit records.
- File a formal protest: Submit the required county form with your evidence before the deadline.
- Attend the hearing: Keep your presentation focused on accurate comps and objective data. The county will explain its methodology.
- Consider an appeal: If you disagree with the decision, explore an appeal to TERC. Check the exact filing requirements and timelines before proceeding.
What to bring to a protest
- Comparable sales sheets from the same neighborhood and time frame
- Photos and contractor bids that document condition issues
- A recent independent appraisal, if available
- Permit records for additions or to confirm no major changes
- Your property record card and prior assessment history
Planning around escrow and sale timing
- Expecting an increase? Ask your mortgage servicer how and when your escrow analysis will adjust your payment.
- Selling this year? Get a broker price opinion or independent appraisal to set expectations. The sale will hinge on today’s comps and appraisal, not just the county value.
- Coordinate tax proration: Confirm how your closing will prorate taxes. Some use last year’s bill. Others use an estimated current-year amount.
- Remodeling or building? Know that permits and updates may trigger reassessment when the county updates your record.
