The Douglas County Nebraska valuation protest window runs June 1 through June 30 every year. File by the deadline or the assessor's value stands for the year.
The Douglas County valuation protest deadline is June 30 each year, with filing open from June 1. For 2026, protests must be signed and filed or postmarked by Tuesday, June 30, 2026. After that, the assessor's January 1 value stands and drives the tax bill paid in 2027.
Why is the protest window only 30 days?
Nebraska revalues every home every year as of January 1, and counties mail valuation change notices by June 1. State law then closes the protest window on June 30, so the notice and the deadline arrive in the same month. Each year's value gets exactly one short contest window, and a value nobody challenges becomes the basis for the following year's bill. That cycle is why a property tax appeal in Douglas County is an annual decision rather than a once-a-decade one.
What does this mean for you?
County taxable value has climbed about 38 percent since 2021, so a value that was right a few years ago can be wrong now. A Fair Appeal review is free, and FairAppeal charges only when a protest actually lowers the tax. The full Douglas County protest guide covers how the referee review works.

Frequently asked questions
- What is the Douglas County valuation protest deadline for 2026?
- Tuesday, June 30, 2026. Filing opens June 1, and a protest must be signed and filed or postmarked by the 30th. The window repeats every year on the same dates under Nebraska law.
- What happens if you miss the June 30 protest deadline?
- The assessor's January 1 value stands for the year and drives the bill paid the following year. Because Nebraska revalues annually, a new value and a new June window arrive the next year, and the protest right renews with them.
- Does filing a Douglas County protest cost anything?
- No. There is no county filing fee, and the referee appointment is optional and can happen by phone. Only a later appeal to the state Tax Equalization and Review Commission carries a filing fee.
