How to Appeal Your Property Taxes in Salt Lake County Before September 15, 2026

The deadline to appeal your Salt Lake County property tax valuation for 2026 is September 15, and if you believe your home is overvalued, this is your window to do something about it before your tax bill is finalized for the year.

When Does Salt Lake County Accept Appeals

Salt Lake County began accepting appeals August 1, 2026, and the window closes September 15, 2026, at 5pm, with no automatic extension since that date does not fall on a weekend or holiday this year. The county mails its Notice of Property Valuation and Tax Changes by late July, so if you have not opened that envelope yet, that is the number to check first.

What Are You Actually Appealing

You are not appealing your tax bill directly. You are appealing the market value the county assessor placed on your home as of January 1, 2026. Utah homeowners also receive the primary residential exemption, which reduces your taxable value by 45 percent, meaning most owner-occupied homes are taxed on just 55 percent of assessed market value. Your tax bill is calculated from that reduced number, so a successful appeal on the underlying value flows through to a lower bill.

What Evidence Do You Need

The Salt Lake County Board of Equalization will not accept an appeal without supporting evidence attached. The strongest evidence is three to five comparable sales from within a year of the January 1 lien date, a recent independent appraisal, or your own purchase or refinance closing documents if those happened recently.

How Do You File

You can file online through Salt Lake County's Online Property Tax Appeal portal, by emailing propertytaxappeals@saltlakecounty.gov, by mail, or in person at 2001 South State Street, Suite N3-300, Salt Lake City. The board must decide within 60 days of filing, and if you disagree with their decision, you can escalate to the Utah State Tax Commission within 30 days after that.

How Much Could You Actually Save

Utah's average effective property tax rate runs around 0.55 percent after the primary residential exemption. On a home assessed at $600,000, a successful appeal that reduces your assessed value by $50,000 would save roughly $150 to $180 a year, not a fortune, but real money that compounds every year you own the home, and the appeal itself costs nothing but your time if you handle it yourself.

Do You Need a Lawyer or Appraiser

Most successful homeowner appeals in Salt Lake County are handled without professional representation. The hearing is informal, you typically get 10 to 20 minutes to present your comparable sales, and the board consists of appointed community members, not judges. A paid appraisal can strengthen a borderline case, but weigh that cost against your potential savings before hiring one.
