Property taxes in Douglas County are calculated by multiplying your assessed value by the consolidated mill levy for your tax district. The levy is set by elected bodies; the value is set by the County Assessor. Only one of those is open to challenge by an individual owner — the value. This guide walks through every step of that challenge for the 2026 cycle.
When you can file
The Douglas County Board of Equalization accepts written protests between June 1 and June 30 each year. There is no partial-month tolerance: a protest postmarked or e-filed on July 1 is not heard. The thirty-day window is the same regardless of whether your property received a notice of valuation change.
If the BOE’s final decision does not satisfy you, you have until September 10 to appeal to the Tax Equalization and Review Commission (TERC). Miss that, and the value stands for the year.
Deciding whether your case is worth filing
Filing is free. The hidden cost is the hour or two you spend gathering evidence, plus the small reputational tax of telling the assessor your comp set looks bad. Before that effort, do a five-minute screen:
- Pull your property record from the Douglas County Assessor’s online lookup. Note the assessed value, square footage, bedroom count, and year built.
- List three to five sales of similar properties within roughly a half-mile that closed in the prior calendar year. Look for matches on age (within ten years), size (within ten percent), and basic condition.
- Compute the median sale price of that small comp set. If the assessor’s value is meaningfully above that median, you have a starting case. If it is at or below, the protest is unlikely to win.
Grounds Douglas County actually accepts
Nebraska statute recognizes a small number of valid grounds for protest. The two that succeed most often in residential filings are:
- Overvaluation by market evidence.Comparable sales from the prior twelve months support a lower value than the assessor’s opinion.
- Unequal appraisal. Other comparable properties in your area are assessed at a lower percentage of their market value than yours. This is the Neb. Rev. Stat. § 77-1502 argument, covered in its own post.
Grounds the BOE will not act on include: your tax bill being higher than last year (taxes are not value), your inability to pay, dislike of the mill levy, and general inflation arguments. Pick a ground tied to value, not to taxation.
Building the evidence packet
A complete packet has four parts: a one-page protest letter stating the ground and the requested value; the comparable-sales analysis with five to seven sales; photographs of any condition issues; and supporting documents (recent appraisal, sale of the subject property, repair estimates).
The hearing officer reads dozens of protests per week. A short, ordered packet with one clear request beats a long, exhaustive one. Lead with your strongest comparable; everything after it is corroboration.
Strong comparables share four attributes with your property: location (same school district, ideally same neighborhood); size (within ten percent of finished square footage); age (within ten years); and basic condition. Adjust for differences in writing. The BOE will not adjust for you.
Filing the protest
File using Nebraska Form 422. Douglas County accepts electronic submission through the assessor’s portal, paper delivery to the County Clerk’s office, and postmarked mail. E-filing produces an immediate confirmation; paper does not. If you mail, send certified.
You can file one Form 422 per parcel. If you own multiple parcels under protest, file separately for each. Do not combine.
The informal review and the hearing
Most protests are first reviewed by a hearing officer working from the record you submitted. If the officer agrees with your evidence, you’ll receive a recommended adjustment without ever appearing. This happens often enough that you should treat the written packet as the main event, not the warm-up.
If the officer does not recommend the adjustment you asked for, you may be offered a brief in-person or telephone hearing before the Board. Be ready to make your case in five minutes: one sentence on the ground, two on your best comparable, one on the value you’re requesting.
After the decision
The Board issues final decisions in late July or early August. If your protest succeeds, the new value flows automatically to the taxing bodies; you do not need to do anything to claim the reduction. If it fails or partially fails, your TERC deadline is September 10. TERC appeals are a different forum and a different evidentiary standard; most owners stop at the BOE.
