How to Protest Your Property Assessment in Omaha: A Step-by-Step Guide

If your Omaha-area property assessment looks too high, the strongest protest is not simply, “My value went up too much.” The goal is to show what the property was actually worth as of the county’s valuation date and give the county board enough evidence to support the value you are requesting.

For most homeowners, that means checking the county’s property record, choosing genuinely comparable sales, accounting for meaningful differences, documenting condition or factual errors, and asking for a specific value that the evidence supports.

First, know what you are actually protesting

A valuation protest challenges the county assessor’s opinion of the property’s actual value. It is not a protest of Nebraska’s property-tax system, the levy set by a school district, or the fact that the tax bill feels high.

That distinction matters because the county board needs evidence about value. If your complaint is only that your taxes increased, the board still needs a reason to conclude the assessed value itself is wrong.

For a broader explanation of how the assessment and tax bill fit together, see Omaha Property Taxes, Assessments & SIDs. If you are comparing the county’s value with a likely sale price, see Assessed Value vs. Market Value in Omaha.

Step 1: Decide whether the assessed value may actually be too high

An assessment increase by itself is not proof that the new value is wrong. The better question is: Could this property reasonably have sold for the assessed amount as of January 1 of the tax year?

If the county has the home assessed at $450,000 and the best market evidence supports roughly $445,000 to $460,000, the increase may be frustrating without being a strong valuation protest. If the same assessment is $450,000 but several strong comparable sales support roughly $410,000 to $425,000, there may be a meaningful case to present.

• Do not start with the percentage increase.
• Do not start with what you paid years ago.
• Do not start with what a neighboring owner says their assessment is.
• Start with the subject property and the best evidence of actual value as of January 1.

Step 2: Check the county property record for errors

Before pulling comparable sales, make sure the county is valuing the property you actually own. A factual error can affect the analysis and may be easier to explain than a broad disagreement about the market.

• Above-grade square footage
• Finished basement area
• Bedroom and bathroom count
• Garage size
• Year built or effective age
• Lot size and property type
• Quality or condition classification
• Additions, outbuildings, pools, or other improvements

Use the Douglas County Assessor/Register of Deeds for Douglas County properties or Sarpy County Property Search for Sarpy County properties.

Step 3: Choose comparable sales that actually support the argument

This is where many protests become weak. Finding three homes that sold for less is not the same thing as finding three good comparable sales.

Nebraska law describes comparable sales as recent sales of properties similar in significant physical, functional, and location characteristics and in how those characteristics contribute to value. The law also directs attention to issues such as unusual financing, zoning, distressed transfers, substantial improvements, and whether the properties are truly in a similar market area.

Comparison factor	Usually more persuasive	Usually less persuasive
Location	Same subdivision or genuinely similar nearby market area	A cheaper sale across town with different buyer demand
Style	Ranch compared with ranch, two-story with two-story when possible	Using a very different design simply because the price is lower
Size	Similar above-grade living area and functional utility	A much smaller home with a lower total sale price
Age and quality	Similar construction era, quality, updates, and condition	A dated or distressed home compared with a renovated subject
Lot and garage	Similar lot utility, garage capacity, and major site features	Ignoring acreage, cul-de-sac, backing conditions, garage differences, or other meaningful features
Sale timing	Recent qualified sales near the January 1 valuation date	Old sales from a different market when better evidence exists

The goal is not to cherry-pick the lowest possible sales. It is to show the county a group of sales that a reasonable buyer would have compared with the subject property.

Step 4: Decide what value you are asking for

The protest form asks for a requested valuation. This should not be a wish number. It should be the number you can defend with the evidence you are submitting.

Suppose a home is assessed at $450,000. After reviewing the strongest comparable sales, you conclude that the best-supported range as of January 1 is approximately $415,000 to $425,000. Asking for $420,000 may be much more credible than asking for $350,000 simply because that would create a larger tax reduction.

A useful requested value should answer three questions:

• What range do the strongest comparable sales support?
• What differences between those homes and yours need to be accounted for?
• Can you explain why the requested number is more supportable than the county’s current value?

This is essentially a property-specific market-value exercise. My broader guide to how an Omaha home’s market value is determined explains many of the same comparison principles.

Step 5: Build an evidence packet that is easy to follow

More pages do not automatically make a better protest. A strong packet makes the reasoning easy to understand.

• A short summary. State the assessed value, requested value, and the central reason for the change.
• A comparable-sales table. Show addresses, sale dates, sale prices, size, style, age, garage, and the features that make each sale relevant.
• A map. Show where the comparable sales are in relation to the subject property when location is part of the argument.
• Property photos. Use current photos when condition, deferred maintenance, damage, location influence, or another visible issue affects value.
• Repair or condition documentation. Estimates, inspection information, or contractor documentation can help explain a condition issue when relevant.
• County-record corrections. Point out incorrect square footage, finished area, garage information, or other factual errors.
• A recent appraisal, if you already have one. A relevant appraisal can be useful evidence, although the county still determines the tax assessment.
• A CMA or BPO. A market analysis from a licensed real estate professional can organize comparable-sales evidence and support a requested market-value range.

Can a Realtor prepare a CMA for a Nebraska property-tax protest?

Yes. Nebraska law expressly allows a real estate licensee to prepare a broker’s price opinion or comparative market analysis for real-property tax appeal purposes. The statute also makes an important distinction: that opinion or analysis is not an appraisal and should not be represented as one.

That makes a CMA especially useful when the homeowner needs help identifying appropriate sales, organizing the comparison, and determining a supportable market-value range. An appraiser, attorney, accountant, or tax professional may still be appropriate when the property or appeal is unusually complex.

You can read the rule directly in Nebraska Revised Statute § 81-885.16.

Step 6: Write a reason that connects the evidence to the requested value

The written explanation does not need to sound like a legal brief. It should tell the reviewer what is wrong with the current value and why your evidence supports a different one.

The exact wording should match the real evidence for the property. Do not claim repairs, condition problems, or comparable characteristics that you cannot document.

Step 7: File the protest during the June window

Nebraska’s regular valuation protest period runs from June 1 through June 30. State guidance requires the protest to be written, signed, and filed with the county clerk. Nebraska provides Form 422 and Form 422A; counties may also provide an approved electronic form.

Form 422 separates land, building, and total values. Form 422A allows the real-property valuation to be stated in total. Use the county’s current-year instructions rather than assuming last year’s filing method is unchanged.

Douglas County

Douglas County provides an official Board of Equalization online protest portal where property owners can create a protest and attach supporting evidence during the protest season. Check the county’s current instructions before filing because submission requirements can change from year to year.

Sarpy County

Sarpy County currently allows Form 422 protests to be filed online, in person, or by mail during the June 1 through June 30 window. Sarpy County specifically tells protesters that they are responsible for presenting relevant evidence supporting the requested valuation.

What changes for protests beginning in 2027?

Nebraska’s 2026 LB 803 changes the documentation requirement beginning January 1, 2027. The Nebraska Department of Revenue summarizes the new rule this way: a taxpayer filing a valuation protest must include documentation sufficient for the county board of equalization to determine a different valuation.

In practical terms, a bare statement such as “my assessment is too high” becomes even less useful. The requested value and supporting evidence need to arrive with the protest. See the state’s 2026 legislative-change summary for the current guidance.

What happens after you file?

The county board of equalization reviews valuation protests and may use referees or other review procedures. The exact process varies by county. In Sarpy County, for example, the Board uses an independent appraisal firm and referee hearings, and the protester may present information related to the property’s value as of January 1.

Keep copies of everything you submit. If a hearing or meeting is offered, be ready to explain the requested value in a few minutes: the subject property, the strongest comparable sales, the most important differences, and why the evidence supports your number.

What if the county board does not agree?

A property owner who timely protested at the county level may be able to appeal the county board’s decision to the Nebraska Tax Equalization and Review Commission, commonly called TERC.

TERC’s filing deadline is not the same for every county or every year. For 2026 valuation-protest decisions, TERC currently lists September 10, 2026 for Douglas County and Lancaster County, and August 24, 2026 for all other counties, including Sarpy. The Commission requires its appeal form, the applicable filing fee, and a copy of the decision being appealed. TERC currently does not offer electronic filing.

Use the official TERC appeal page for the current deadline, fee, and instructions.

Common mistakes that weaken a valuation protest

• Arguing about the tax bill instead of value. The county board is reviewing the assessment.
• Using list prices instead of closed sales. An asking price does not prove what buyers actually paid.
• Cherry-picking cheap comps. Similarity matters more than finding the lowest number.
• Ignoring the January 1 valuation date. Later sales can sometimes provide context, but the question is value as of the statutory date.
• Comparing total price without comparing the homes. Size, style, condition, garage, lot, location, and updates all matter.
• Requesting a number with no explanation. The requested valuation should flow from the evidence.
• Waiting until the deadline to gather evidence. The June window is short, and beginning in 2027 the documentation requirement becomes even more important.

A practical property-assessment protest checklist

1. Pull the current county property record and assessed value.
2. Confirm the property characteristics are accurate.
3. Identify the January 1 valuation date for the tax year.
4. Find the strongest recent qualified comparable sales.
5. Compare location, style, size, age, condition, garage, lot, and important updates.
6. Determine a supportable market-value range.
7. Choose a specific requested valuation inside that evidence-based range.
8. Prepare a concise summary, comp table, photos, and other relevant documentation.
9. Complete the county’s current protest form and file it no later than June 30.
10. Keep a complete copy of the protest and every attachment.
11. Prepare to explain the case at any hearing or referee review.
12. If necessary, verify the current TERC deadline immediately after receiving the county board’s final decision.

Frequently asked questions

Can I protest just because my assessed value went up a lot?

You can protest an assessed value you believe is incorrect, but the percentage increase alone does not establish the property’s actual value. A stronger case shows why the new assessment exceeds the value supported by comparable sales or other relevant evidence.

How many comparable sales should I use?

There is no universal number that makes a protest successful. A small group of highly relevant sales can be more persuasive than a long list of weak comparisons. The quality and similarity of the sales matter more than volume.

Can I use Zillow or another online estimate as my evidence?

An automated estimate can be a reason to investigate, but it does not explain which sales are most comparable or why the requested value is appropriate. Property-specific market evidence is usually more useful.

Does a recent appraisal help?

It can, especially when the appraisal’s effective date and property condition are relevant to the January 1 valuation date. The county board is not required to adopt a private appraisal automatically, but it can be meaningful evidence.

Can a real estate agent help me with the comps?

Yes. Nebraska law permits licensed real estate professionals to prepare a broker price opinion or comparative market analysis for real-property tax appeal purposes. The analysis should be described as a CMA or BPO, not an appraisal.

Can I file after June 30 if I missed the deadline?

The regular Nebraska valuation-protest window closes June 30, and counties are limited in accepting untimely protests. Other procedures can exist for specific situations, so contact the county clerk or assessor promptly rather than assuming a late Form 422 will be accepted.
