Appealing Your Clark County Property Tax Assessment: What Homeowners Need to Know

Every December, Clark County mails a Notice of Value to property owners across the valley — and every year, a share of those notices land higher than homeowners expect. If yours looks off, you have a narrow window to do something about it. Here's how the appeal process actually works, and where an independent appraisal fits in.

How Nevada Calculates Your Taxable Value

Nevada doesn't tax your home based on its market value the way many states do. Instead, the Assessor calculates a taxable value: the appraised value of your land plus the replacement cost of your improvements, minus depreciation of 1.5% for each year of the structure's age. That taxable value is then assessed at 35%, and your tax bill is calculated from the assessed value.

Because this formula relies on replacement cost rather than actual sales activity in your neighborhood, it can drift away from what your home would actually sell for — especially in a market like Las Vegas, where costs to rebuild and the price a buyer will pay don't always move together. That gap is exactly what an appeal is designed to address.

Nevada's Tax Cap Doesn't Mean Your Assessment Is Right

Many homeowners assume Nevada's tax abatement law protects them from ever needing to appeal. It's true that your actual tax bill is capped — a maximum 3% annual increase for an owner-occupied primary residence, and 8% for other residential and commercial property. But the cap limits how much your bill can rise year to year; it does not limit how much your underlying assessed value can climb. If your assessed value keeps climbing above what the cap allows you to be billed for, that gap accumulates as a "shadow" assessment — one that gets fully realized the moment the property changes ownership or loses its primary residence status. In other words, the cap buys you time, but it doesn't fix an inflated assessment.

The Appeal Deadline: January 15

This is the single most important date in the entire process. The Clark County Assessor mails Notice of Value forms by December 18 each year, which gives property owners less than a month — spanning the holidays — to review the notice and decide whether to appeal. The appeal must be received by the Clark County Board of Equalization on or before January 15 of the fiscal year (or the next business day, if January 15 falls on a weekend or holiday). Miss it, and you generally have to wait for next year's notice to try again.

To file, you'll complete Form 5101SBE and submit it to the Clark County Assessor's Office at 500 S Grand Central Parkway, 2nd Floor, Las Vegas, NV 89155, either in person or by mail. County Board hearings begin in January and must conclude by the end of February. If you disagree with the County Board's decision, you can escalate to the Nevada State Board of Equalization, with a filing deadline of March 10.

What the Board Actually Wants to See

The Board of Equalization is not interested in "my taxes are too high" as an argument — Nevada tax experts are explicit that ability to pay isn't something the Board has authority to consider. What moves the needle is objective evidence that the Assessor's taxable value doesn't match reality. That generally comes down to two categories:

• Factual errors in the Assessor's record — incorrect square footage, wrong bedroom or bathroom count, an inaccurate year built, or a missed depreciation adjustment. Even a couple hundred square feet of overstated living area can inflate a taxable value meaningfully.
• Valuation evidence — comparable sales, an independent appraisal, or documented condition issues that support a lower value than the Assessor's replacement-cost calculation produced.

Where an Independent Appraisal Comes In

Many homeowners try to build their own case with online estimates or a handful of self-selected comparable sales. The problem is that the Board sees this constantly, and the Assessor's office is prepared to counter with its own comparables. A certified appraisal carries more weight for a simple reason: it follows USPAP standards, it's backed by a physical inspection, and it applies the same bracketing and comparable-selection discipline a lender would require — not a homeowner's best guess at what "similar" means.

A tax appeal appraisal lays out:

• A defensible opinion of value as of the relevant assessment date, supported by verified comparable sales
• Documentation of any condition, size, or feature discrepancies between your property and the Assessor's record
• A report format the Board is accustomed to reviewing, which speeds up your hearing rather than inviting follow-up questions

Timeline and Cost

Given the compressed December-to-January window, we recommend ordering a tax appeal appraisal as soon as your Notice of Value arrives rather than waiting until the deadline is close. Most tax appeal appraisals are completed within 2–5 business days of inspection, with fees starting at $425 depending on property type and complexity.
