Property Valuation in Nebraska: What a County Assessor Does

If you own land, a house or a business in Nebraska, the county assessor decides what your property is worth for tax purposes. Nebraska has 93 counties, and each runs its own assessor's office from or near the courthouse. Our directory lists 92 of them, from the Brown County Assessor's Office at 148 West 4th Street in Ainsworth to the Dundy County Assessor's Office at 112 West 7th Avenue in Benkelman. This page explains who oversees these offices, how rural and metro counties differ, and what to bring when you visit.

The assessor's job is narrower than most people expect. The office lists every parcel, classifies it, and estimates its value as of January 1 each year. It does not set tax rates and it does not collect payment. Levies come from the county, school districts, cities, natural resources districts and other local bodies. The county treasurer mails the bill and takes the money. Knowing which office handles which step saves you a wasted trip to the courthouse.

Nebraska law also treats property classes differently. Residential, commercial and industrial real estate is assessed at 100 percent of actual value. Agricultural and horticultural land is assessed at 75 percent of its market value. Farmland is valued by use and soil capability, such as irrigated cropland, dryland and grassland. A rancher in Box Butte County will therefore ask the assessor very different questions than a homeowner in Beatrice.

The State Agencies That Oversee Nebraska County Assessors

County assessors do not work alone. The Property Assessment Division of the Nebraska Department of Revenue supervises the system statewide. Its head, the Property Tax Administrator, issues guidance, reviews assessment practices and checks each county's work every year. The division also publishes annual reports and opinions that test whether a county's values are close to market value and consistent across property types.

The Nebraska Tax Equalization and Review Commission, usually called TERC, is the second state body to know. TERC hears appeals from county board of equalization decisions on individual properties. It can also order adjustments to whole classes of property in a county when the numbers show values are out of line. For a resident, that creates three layers: the assessor, the county board, and then TERC.

Assessors estimate value with familiar methods. They compare recent sales of similar properties, calculate the cost to rebuild minus depreciation, and, for rental or commercial property, look at the income a building produces. Sales are the backbone of the work. When a property sells, the buyer and seller file a real estate transfer statement, and the assessor uses that price to test whether nearby values are fair.

Assessors are county officials, usually elected to four-year terms, and they must hold a state assessor certification and keep up their continuing education. State law requires every property to be physically inspected and reviewed at least once every six years. That is why an appraiser may appear at your door, or a county vehicle may drive your road, in a given year. In a small county, the same few people handle the review cycle, the exemption paperwork and the front counter.

Rural Courthouses and Metro Offices: How Nebraska Counties Differ

Most Nebraska assessor offices serve small populations spread over large areas. The Arthur County Assessor's Office lists a mailing address of PO Box 126 in Arthur, and Arthur is one of the least populous counties in the state. The Rock County Assessor's Office in Bassett also uses a post office box, PO Box 446. In places like these, staff are few, hours can be limited, and a phone call before a long drive is sensible. Ranch country such as the Sandhills means large grassland parcels and relatively few sales.

Counties closer to population centers have more parcels and more transactions to track. The Washington County Assessor's Office at 1555 Colfax Street in Blair serves a county within commuting range of Omaha. Hamilton County, with its office at 1111 13th Street in Aurora, and Platte County, at 2610 14th Street in Columbus, cover productive irrigated cropland alongside town lots. Gage County, at 612 Grant Street in Beatrice, has a larger town at its center, so residential work makes up a bigger share of the files. Douglas and Lancaster counties, home to Omaha and Lincoln, run far larger operations than any of these.

Northeast and central Nebraska fall somewhere in between. The Knox County Assessor at 206 Main Street in Center and the Custer County Assessor's Office at 431 South 10th Avenue in Broken Bow each balance farm and ranch ground against small-town housing. Expect friendly, hands-on service, but also expect that the person who answers may be the assessor.

Western Nebraska adds geography. Offices in the Panhandle, including Dawes County in Chadron, Morrill County in Bridgeport and Deuel County in Chappell, serve ranch and dryland wheat country with long drives between towns. Most of the Panhandle observes Mountain Time, so a call from Omaha or Lincoln should allow for the one-hour difference, especially close to the end of the business day.

Using a Nebraska Assessor's Office: Records, Exemptions and Deadlines

Most visits fall into a handful of tasks. Bring your parcel number or street address if you have it, because assessors file records by parcel. Photo identification helps when you sign exemption forms. The list below covers the most common requests.

Before You File a Protest in Nebraska

A valuation protest goes to the county board of equalization, and the county clerk accepts the filing. The usual deadline is June 30, so read your notice for the exact date and form. Start by talking with the assessor. A wrong square footage, a demolished outbuilding or a misclassified lot is often corrected informally, with no hearing. If you still disagree, gather evidence: recent sales of similar homes nearby, a recent appraisal, repair estimates and dated photos. Decisions begin with a presumption that the assessor's value is correct, so the burden is on you to show it is not. If the board rules against you, the next step is an appeal to TERC, and that filing window is short.

Reaching an Office Before You Go

The phone numbers in our listings let you confirm hours and ask what to bring. Examples include Hamilton County at 402-694-2757, Gage County at 402-223-1308, Washington County at 402-426-6800 and Box Butte County at 308-762-6100. Some small counties combine assessor duties with other courthouse functions, so if nobody answers at a listed number, try the county clerk. Always confirm hours directly, since small offices sometimes close at lunch or on training days.

Property assessor offices in Nebraska operate under state property tax statutes that specify how properties must be valued, how often reappraisals occur, and what exemptions are available to qualifying homeowners. The state department of revenue or taxation typically provides oversight and technical guidance to county assessors to ensure consistent valuation practices statewide.

Assessor locations are available in 92 cities across Nebraska. They are spread across 92 counties.

Cities with the highest concentration include Dakota, Falls, Beaver, where high real estate activity and complex commercial properties create greater demand for assessor services and property valuation resources.

Property owners in Nebraska should verify that their primary residence homestead exemption is active and confirm the annual appeal deadline with their local assessor office, as missing the deadline means waiting until the following tax year to contest a valuation.

Many county assessor offices in Nebraska now offer online property search tools where homeowners can view their assessed value, recent sales history, and exemption status without visiting the office. If you have questions about a recent reassessment notice, calling or emailing the assessor's office is often the fastest way to get a response before filing a formal appeal.

A Year in the Life of a Nebraska Property Tax Bill

Nebraska's assessment calendar repeats every year, and knowing it keeps you from missing a deadline. Values are set as of January 1. Through winter and spring, assessors finish reviews, process sales and take exemption applications. By June 1, notices go out where values have changed. June 30 is the key date, because it closes both the protest window and the homestead exemption filing period. County boards then hold hearings over the summer, and local governments adopt budgets in late summer and early fall.

Tax statements arrive in December from the county treasurer, not the assessor. Taxes are generally paid in two halves, with the first typically delinquent after May 1 and the second after September 1. Confirm exact dates with your treasurer. If you live in Nemaha County, the assessor's office is at 1824 N Street in Auburn. Furnas County's is at 912 R Street in Beaver. Both are examples of courthouse-area offices where a short visit usually resolves a records question faster than email.

When the assessor changes the value of your real property, the county mails a notice by June 1. A written protest generally must reach the county clerk by June 30. You can protest even if your value did not change, as long as you file on time. The county board of equalization then holds hearings, usually in the summer. Read the notice carefully, because it lists the filing details and the form to use. If you did not receive a notice, call the assessor before the deadline passes.

Do both, in that order. Call or visit the assessor first and ask to see your property record card. Factual errors, such as wrong square footage, a building that no longer exists or an incorrect classification, can often be fixed without a hearing. If the assessor does not agree, file a formal protest with the county clerk before the deadline so the county board of equalization can hear your case. Filing the protest protects your rights even while you are still talking with the assessor, so do not wait for those conversations to finish.

State law assesses agricultural and horticultural land at 75 percent of its market value, while residential and commercial property is assessed at 100 percent. Farmland is also valued by how it is used and by soil capability, so irrigated cropland, dryland and grassland each carry their own per-acre values. If your acres are classified wrongly, for example grassland listed as irrigated, ask the assessor to review it. Bring maps, irrigation records or other documents that show how each field is actually used. Your county office can tell you which records it accepts.

File Form 458 with your county assessor between February 1 and June 30. The exemption is aimed at homeowners who are seniors, have qualifying disabilities, or are disabled veterans or surviving spouses of veterans, and some categories include income limits. Applications are filed each year, so do not assume last year's approval carries over. The assessor's staff can tell you which category fits you and what proof to bring. Because the June 30 cutoff is firm, submit the form early rather than waiting for the final week, when counter lines can be longer.

Owners of depreciable tangible personal property used in a business or farm, such as machinery, equipment and fixtures, file a personal property return, Form 312, with the county assessor by May 1. Filing late can bring a penalty, so ask your assessor about the current rules. An exemption allowance may reduce or eliminate the tax for small operations, but you still need to ask how it applies. Licensed vehicles are handled differently, through the county treasurer at registration, and do not belong on this return.

You can appeal to the Nebraska Tax Equalization and Review Commission, known as TERC. Its filing window is short and runs from the board's decision, so check the date on your decision notice right away. TERC holds hearings, and you will need evidence such as comparable sales, an appraisal or photos of defects. The assessor's value starts with a presumption of correctness, so a well-documented case matters. Keep copies of everything you submitted to the county, since TERC will want to see what the board reviewed.

Use the post office box for mailed forms, and call first for anything urgent. The Arthur County Assessor's Office lists 308-764-2203, and the Rock County Assessor's Office lists 402-684-3831. Ask for the courthouse location and open hours, since small offices may not keep a full schedule. If you plan to mail an exemption form or protest near a deadline, allow extra days for delivery. For a protest, remember that the filing goes to the county clerk, so confirm that office's address as well.
