Washoe County, NV Property Tax Appeal Guide for 2027

What deadline matters first

Washoe County lists January 15 as the County Board appeal deadline for a property owner who wants the Washoe County Board of Equalization to review a real-property valuation. For the 2027 policy year, January 15, 2027 falls on a Friday, so the regular deadline is January 15, 2027. The county also explains that your appeal must be filed by January 15 for County Board review, and Nevada law requires assessment notices to be mailed on or before December 18. Washoe County Assessment Notices NRS 361.300

The filing is made as a Petition for Review of Assessed Valuation to the County Board. Washoe County recommends talking with the Assessor's representative first so you understand how the taxable value was set, but that conversation does not replace the filing deadline.

For scale, a Washoe County Board of Equalization January 9, 2025 meeting document reported a volume of 13 appeals at that point and about 190,000 parcels in the county. That appeal count is a recent example only, not a prediction for the 2027 filing season. Washoe County Board of Equalization January 9, 2025 minutes

In this draft's verified policy data, TaxSauce uses an effective tax rate of 0.0064, or 0.64%, for rough planning. That means a $10,000 taxable-value difference is about $64 in estimated annual tax before district-specific rates, caps, abatements, and rounding.

The common value appeal

The common value filing reason is Taxable value exceeds full cash value. In normal homeowner language, this means you believe the taxable value on the assessment is higher than the property's market value as of January 1, 2027.

Nevada uses the official term full cash value for market value. Nevada law says that if the County Board finds full cash value on the January 1 valuation date is below taxable value, the Board corrects the land value and/or improvement obsolescence so taxable value corresponds as closely as possible to full cash value. NRS 361

Recent comparable sales are often the easiest evidence for a homeowner to understand. Nevada regulations allow prices paid in market transactions for comparable property as evidence of market value. NAC 361.631

Other reasons you might appeal

Washoe County's regular valuation review is not limited to a comparable-sales argument. Other official filing reasons may fit if the problem is in the county's data, the calculation, or equal treatment compared with other property.

• Taxable value incorrectly determined: Use this when the Assessor may have used the wrong improvement characteristics, land classification, depreciation, obsolescence, land value, cost data, or similar valuation input.
• Inequity exists: Use this when a similarly used property in a comparable location is assessed materially lower, consistent with Nevada equalization terminology.
• Overvaluation or excessive valuation by reason of undervaluation or nonassessment of other property: Use this when the complaint is that your property is overvalued because other property in the county is undervalued or omitted from assessment. This is a more specific statutory equalization complaint, not just a general fairness concern.

These labels matter because the Board hears valuation and equalization issues. Washoe County states the County Board hears protests alleging taxable value was incorrectly determined or exceeded full cash value. Washoe County taxpayer petition instructions

If your Notice of Assessment says something else changed

A Notice of Assessment is the county's assessment notice showing the values and property details the Assessor placed on your property for the tax year. It is not the same thing as a tax bill. The tax bill comes later and applies tax rates, districts, and any applicable caps or abatements to the value. Washoe County Assessment Notices

If the notice shows a new building, remodel, changed square footage, different land use, changed classification, or another property-detail change, start there. A data or calculation problem may support Taxable value incorrectly determined even when recent sales are not the main issue.

If the notice value rose but the property facts look correct, compare the value with arm's-length market sales near the January 1, 2027 valuation date. That may support Taxable value exceeds full cash value if the sales point to a lower market value.

What evidence helps

For a Taxable value exceeds full cash value filing, helpful sales are usually arm's-length market transactions for properties with comparable use, location, and physical characteristics. Avoid relying on distressed, related-party, foreclosure, short-sale, bulk, non-open-market, or otherwise non-arm's-length transfers unless you clearly explain why they are still useful or how they should be adjusted.

Nevada and Washoe County do not publish a fixed residential comparable-sale radius, living-area variance, lot-size variance, or maximum number of comparable sales for County Board petitions. For standardized preparation, TaxSauce uses a conservative January 1, 2026 through January 1, 2027 sale window, a preferred 1-mile radius, and up to five comparable sales. These are TaxSauce screening defaults, not Washoe County legal caps.

Other useful evidence can include photos, repair estimates, permits, sketches, appraisal records, and documents showing that the county's property characteristics are wrong. If you ask, the Assessor must provide the most recent appraisal and related sales or materials used to determine or defend taxable value within 15 days, subject to copying fees.

Washoe County says evidence should be submitted to the County Clerk so it is received five days before the hearing. If you do not submit evidence in advance, you should bring eight copies to the hearing. Materials submitted to the Board become public records. Washoe County Board of Equalization FAQ

What the board can and cannot decide

The appeal body is the Washoe County Board of Equalization. Its valuation job is to equalize property values, not to change property tax rates or grant hardship relief. Washoe County states that comments such as taxes being too high or rising sharply, without valuation evidence, are not a basis for a reduction. Washoe County taxpayer petition instructions

The homeowner has the burden to show that the valuation is in error or that taxable value exceeds full cash value. Bring evidence that connects directly to the official reason you choose.

One important protection applies to the common value reason. Washoe County's hearing instructions state that no appeal to the County Board filed on the grounds that taxable value exceeded full cash value may result in an increase in taxable value. Washoe County hearing instructions
