How to Protest Your Property Taxes in Douglas County: Complete 2026 Guide

If you own property in Douglas County, Nebraska, you have the legal right to challenge your assessed value every year. In 2025, the Douglas County Board of Equalization received 4,865 property tax protests, and 47% of all filers received a reduction. The median residential reduction was $30,600— real money that translates directly into lower tax bills. This guide walks you through every step of the 2026 protest process so you can file with confidence.

Why You Should Protest Your Property Taxes

Nebraska’s property taxes are among the highest in the country, and Douglas County assessments have risen sharply over the past several years. If your home’s assessed value exceeds its actual market value — or if it is assessed higher than comparable properties in your neighborhood — you are overpaying. A successful protest lowers your assessed value, which reduces your tax bill for the current year and often sets a lower baseline for future assessments.

There is no cost to file a protest, no penalty for an unsuccessful one, and the county cannot raise your value as a result of your protest. The process is designed to be accessible to homeowners without professional help, though tools like Big Red Value can dramatically reduce the time and effort involved.

Who Can Protest and When

Any property owner (or authorized agent) in Douglas County may protest their assessed value with the Board of Equalization. The filing window opens June 1 and closes June 30every year. There are no extensions — if you miss June 30, you must wait until the following year.

You can check your current assessed value at the Douglas County Assessor’s website. Assessment notices are typically mailed in late April or early May. Review yours as soon as it arrives so you have time to gather evidence.

The Two Legal Grounds for a Protest

Nebraska law provides two distinct bases for a property tax protest. You may argue one or both:

1. Overvaluation: Your assessed value exceeds the actual fair market value of your property. You prove this with comparable sales data, appraisals, or evidence of property condition issues.
2. Unequal appraisal (equalization): Your property is assessed disproportionately higher than similar properties. This is governed by NE Rev. Stat. 77-1502 and requires showing that comparable properties are assessed at lower per-unit values than yours.

Most residential protesters rely on the overvaluation argument, but unequal appraisal claims can be powerful when assessment-to-assessment disparities exist in your neighborhood.

What You Need Before You File

Preparation is the difference between a successful protest and a dismissed one. Gather the following before the June filing window opens:

• Your assessment notice— showing the county’s assessed value, property classification, and square footage
• Comparable sales— recent sales (within the last 12–18 months) of similar properties in your area that sold for less than your assessed value
• Comparable assessments— the assessed values of similar nearby properties (for an unequal appraisal claim)
• Property condition evidence— photos and descriptions of deferred maintenance, structural issues, or functional obsolescence
• A recent appraisal(if available) — particularly useful if obtained for a mortgage refinance or purchase
• Nebraska Form 422 — the official protest form, available from the BOE website

Three Ways to File Your Protest

Douglas County offers three methods for filing your protest. All must be completed by June 30:

1. Online (Recommended)

File through the Board of Equalization website. The online portal walks you through each required field, allows you to upload supporting documents, and provides instant confirmation. This is the fastest and most reliable method.

2. By Mail

Download and complete Nebraska Form 422, then mail it to the Douglas County Clerk’s Office. The form must be received (not just postmarked) by June 30. Mail early to avoid delivery delays.

3. In Person

Deliver your completed Form 422 and supporting documents to the Douglas County Civic Center. In-person filing guarantees receipt but may involve wait times, especially in the final week of June. The BOE office can be reached at 402-444-6510 to confirm hours and location.

Step-by-Step: Filing Your Protest

1. Review your assessment notice. Confirm the property description, square footage, and assessed value are accurate. Errors in property data are common and can be grounds for a protest on their own.
2. Research comparable properties. Use the Assessor’s website to look up assessments of similar homes in your neighborhood. Tools like Big Red Value automate this step and identify the strongest comparables for your case.
3. Choose your legal basis. Decide whether to argue overvaluation, unequal appraisal, or both. If similar homes are assessed at lower per-square-foot values, add equalization as a secondary argument.
4. Complete Form 422. Fill out every required field. See our Form 422 instructions for a field-by-field walkthrough.
5. Attach your evidence. Include comp sheets, photos, appraisals, and any other supporting documentation. Label everything clearly.
6. Submit before June 30. Use the online portal for the fastest confirmation. If mailing, send it early and use certified mail for proof of delivery.

What Happens at Your Hearing

After you file, the BOE will schedule a hearing, typically in July or August. Here is what to expect:

• Hearings are brief — usually 10 to 15 minutes for residential properties.
• You (or your representative) will present your evidence and explain why you believe the assessed value is too high.
• The county assessor’s office will present their justification for the current value.
• Board members may ask questions of both sides.
• You will receive a written decision, usually within a few weeks of your hearing.

Be professional, stick to the data, and keep your presentation focused. Emotional arguments about your tax bill are not persuasive — comparable sales and assessment data are.

Possible Outcomes

The BOE can take one of three actions:

• Reduce your assessed value— the most common favorable outcome. In 2025, 44% of residential protesters received a reduction.
• Affirm your assessed value— the board agrees with the county’s assessment. You may still appeal to TERC.
• Raise your assessed value— extremely rare, but legally possible. This almost never happens in practice.

If You Disagree: Appealing to TERC

If the BOE denies your protest or you believe the reduction was insufficient, you can appeal to the Tax Equalization and Review Commission (TERC). The TERC appeal deadline is September 10. TERC proceedings are more formal and may benefit from professional representation, but homeowners can and do represent themselves.
