How to Appeal a Davis County Property Tax Valuation in 2026

August 04, 20269 min read

If you believe Davis County valued your property above its fair market value, you may appeal the valuation to the Davis County Board of Equalization. For the 2026 tax year, Davis County lists September 15, 2026, as the filing deadline, although Utah law generally allows filing within 45 days after valuation notices are mailed or by September 15, whichever is later.

A successful appeal requires more than saying the increase feels unfair or the tax bill is too high.

The appeal must focus on the property’s market value and should include credible evidence showing why the county’s value is incorrect as of the applicable valuation date.

Important distinction: The Board of Equalization reviews the property’s assessed market value. It does not set tax rates and generally cannot reduce a tax bill merely because the owner believes the taxes are unaffordable.

First, Understand What You Are Appealing

Utah property taxes involve several separate pieces:

  • The county assessor estimates the property’s market value

  • Applicable exemptions determine taxable value

  • Taxing entities adopt certified tax rates

  • The rate is applied to the taxable value to calculate the tax

A valuation appeal challenges the assessor’s opinion of market value—not the tax rate adopted by cities, school districts, the county, or other taxing entities.

The Utah State Tax Commission explains that a county Board of Equalization has authority to consider property value and exemption eligibility, but it does not have authority to change tax rates.

Homeowners should also confirm that the property is receiving Utah’s primary-residence treatment when eligible. Review Utah’s 45% primary-residence property-tax exemption before assuming the problem is solely the market value.

What Is the 2026 Davis County Appeal Deadline?

Davis County’s appeal page listsSeptember 15, 2026, as the deadline for filing a real-property appeal for the 2026 tax year.

The Davis County Assessor also explains that state law requires an appeal to be filed within 45 days after the valuation notice is mailed or by September 15, whichever is later.

Do not wait until the final day.

Gathering comparable sales, correcting property information, obtaining photographs, and preparing a clear value argument can take time. Filing early also gives you an opportunity to correct an incomplete application before the deadline.

Current forms and instructions are available through the official Davis County property-valuation appeals page.

Step 1: Review the Valuation Notice Carefully

When the valuation notice arrives, check:

  • The county’s market value

  • The property address and parcel number

  • The primary-residence designation

  • The listed square footage

  • Bedroom and bathroom counts

  • Basement finish

  • Garage size

  • Lot size

  • Construction quality and condition

  • Outbuildings or other improvements

A factual error may have a direct effect on value.

For example, the county record might show a finished basement that is actually unfinished, a larger living area than the home contains, or an accessory structure that no longer exists.

The Davis County Assessor provides property-valuation information through its official real-property valuation page.

Step 2: Decide Whether the Value Is Actually Unsupported

A large increase does not automatically prove that the valuation is wrong.

The relevant question is whether the property could reasonably have sold for the county’s stated market value as of the assessment date.

Utah real property is generally valued as of January 1 of the tax year. That means the strongest comparable sales are usually properties that reflect market conditions near the January 1 valuation date—not homes listed months later under different conditions.

Ask:

  • What similar homes sold near the valuation date?

  • Are they truly comparable in size, location, age, condition, lot, and improvements?

  • Does the subject property have repair or condition issues the county may not recognize?

  • Did the county rely on incorrect property characteristics?

  • Was there a recent arm’s-length purchase or professional appraisal?

A current listing price is not as persuasive as a closed sale. An automated website estimate is also weaker than verified market evidence.

Step 3: Build a Focused Evidence Package

The property owner carries the burden of presenting evidence that supports a different value.

Useful documentation may include:

  • Recent closed comparable sales

  • A professional appraisal with an appropriate effective date

  • The property’s recent arm’s-length purchase contract and closing statement

  • Photographs documenting condition problems

  • Contractor estimates for significant defects

  • Corrected square footage or property characteristics

  • Engineering, structural, or environmental reports

  • Evidence of access, easement, topography, or location limitations

Keep the presentation direct.

Three strong comparable sales are usually more persuasive than a long list of loosely related properties. Explain the meaningful differences instead of merely submitting addresses.

Appraisal principles also matter when comparing properties for purchase. Read how an appraisal gap guarantee works in a competitive Davis County offer.

Step 4: State the Value You Believe Is Correct

An appeal should not simply ask the county to “lower the value.”

Provide a specific requested value and show how the evidence supports it.

For example:

  • County market value: $725,000

  • Owner’s requested market value: $660,000

  • Evidence: three similar sales between $645,000 and $672,000, plus documented roof and foundation repairs

The requested value must be credible.

An unrealistically low figure can weaken the appeal, even when the county’s original value may also be too high.

Step 5: File the Complete Appeal on Time

Follow the Davis County application instructions carefully.

The appeal package should generally identify:

  • The property owner

  • The parcel being appealed

  • The county’s stated value

  • The owner’s requested value

  • The basis for the appeal

  • The supporting evidence

  • The owner or authorized representative’s signature

Keep proof showing when and how the appeal was submitted.

Davis County’s Tax Administration page provides an upload option for valuation-appeal forms through the official Property Tax Administration and Appeals page.

What Happens After You File?

The county reviews the application and evidence. Depending on the circumstances, the matter may be resolved through an assessor review, hearing officer, or Board of Equalization process.

The Board may:

  • Keep the county value

  • Reduce the value

  • Determine another value supported by the evidence

Utah law generally requires the county Board of Equalization to issue a written decision. The Utah State Tax Commission describes the local process as an appeal to the county Board of Equalization followed by a written decision.

A pending appeal does not necessarily disappear merely because a later tax notice arrives. Davis County’s Treasurer notes that an appeal may still be pending and directs owners to contact Tax Administration for status information.

What If You Disagree With the County’s Decision?

A property owner may appeal the county Board of Equalization decision to the Utah State Tax Commission.

The State Tax Commission states that an appeal must generally be filed within30 days from the county decision date.

That second-level appeal is more formal. The owner should review the written decision, preserve the evidence, identify any factual or valuation errors, and consider whether professional appraisal or legal assistance is appropriate.

Review the official Utah State Tax Commission locally assessed property appeal process.

What About a Late Appeal?

Davis County allows a late appeal application to be submitted for review, but a late filing is not automatically accepted.

The Board of Equalization must determine whether the circumstances justify accepting the appeal. Missing the regular deadline because the owner was busy, forgot, or disagreed with the bill later may not be enough.

The safest approach is to file a complete appeal by the standard deadline.

Common Property-Tax Appeal Mistakes

Arguing only that the taxes are too high

The Board evaluates market value, not whether the tax bill feels affordable.

Using asking prices instead of closed sales

Listings show seller expectations. Closed sales provide stronger evidence of market behavior.

Submitting incomparable properties

A remodeled east-bench home may not support the value of a smaller property in a different neighborhood.

Ignoring the valuation date

Evidence should reflect market conditions near January 1 of the tax year.

Failing to request a specific value

The appeal should state and support the owner’s opinion of market value.

Waiting until September 15

An incomplete application filed at the last minute may leave no time to correct missing evidence.

Will a Successful Appeal Reduce Future Taxes?

A successful appeal changes the value for the tax year being appealed. Future assessments may change again as market conditions, property characteristics, and county reappraisals change.

The appeal does not freeze the property’s value permanently.

It also does not necessarily reduce the tax bill dollar-for-dollar because the final tax depends on taxable value, exemptions, and applicable tax rates.

The Bottom Line

Appealing a Davis County property valuation is not about protesting taxes generally. It is about proving that the assessor’s market value is incorrect.

A strong appeal should:

  • Meet the filing deadline

  • Correct factual property errors

  • Use comparable closed sales near the valuation date

  • Document significant condition issues

  • State a specific supported value

  • Follow the county’s application instructions

  • Preserve the right to appeal the county decision when necessary

Be factual, organized, and realistic. The strongest case is not the loudest complaint—it is the clearest evidence of market value.

Frequently Asked Questions About Davis County Property-Valuation Appeals

What is the Davis County property-tax appeal deadline for 2026?

Davis County lists September 15, 2026, as the 2026 real-property appeal deadline. State law generally allows filing within 45 days after valuation notices are mailed or by September 15, whichever is later.

Can I appeal because my tax bill increased?

You may appeal the assessed market value or exemption treatment. The Board of Equalization does not change the tax rates adopted by taxing entities.

What evidence is best for an appeal?

Strong evidence may include comparable closed sales, a qualified appraisal, a recent arm’s-length purchase, corrected property data, photographs, and documentation of serious condition problems.

Can I use Zillow or another automated estimate?

You may submit available information, but automated estimates are generally less persuasive than verified closed sales or a professional appraisal.

What date matters when proving value?

Utah real property is generally valued as of January 1 of the tax year, so evidence should reflect market conditions near that date.

Can the Board increase my value?

The Board determines the value supported by the evidence. Davis County states that it may agree with the assessor, accept another supported value, or determine a different value based on the record.

Can I appeal after September 15?

A late application may be reviewed, but acceptance is not guaranteed. File by the regular deadline whenever possible.

What if I disagree with the county decision?

You may generally appeal to the Utah State Tax Commission within 30 days after the county decision date.
