How to Appeal Property Taxes in Salt Lake County, Utah (2026 Guide)

Direct answer: For 2026, file your Salt Lake County valuation appeal with the Salt Lake County Board of Equalization by Tuesday, September 15, 2026; Utah’s rule is the later of September 15 or 45 days after the valuation notice is mailed, and Salt Lake County says the deadline moves to the next business day if September 15 falls on a weekend or holiday. File online through the county’s Online Property Tax Appeal portal, or submit the BE-01.2025 Appeal to the Salt Lake County Board of Equalization Real Property with evidence by email, mail, or in person.

How assessments work in Salt Lake County

Salt Lake County values real property as it exists on January 1, 2026. The Assessor completes the assessment roll in May, and the Auditor prepares and mails the Notice of Valuation and Tax Change in late July / by July 22. The 2026 appeal period is the annual Board of Equalization window; the county’s property-tax appeal page says 2026 valuation appeals will be accepted beginning August 1, 2026, while Council-Tax Administration notes the 2026 BOE opens July 31, 2026 and closes September 15, 2026. The safe homeowner rule: gather evidence as soon as the notice arrives, then make sure the appeal is submitted by September 15. (saltlakecounty.gov)

For most homes, values are produced with a computer-assisted mass appraisal (CAMA) system. The county compares properties to market activity and sales; the Assessor’s residential department says the appraisal purpose is to estimate market value for ad valorem tax purposes, with an effective date of January 1 each year. Utah also requires a review of property characteristics once every five years, even though every property is appraised annually with modern appraisal tools. (saltlakecounty.gov)

Important: the Board of Equalization does not lower tax rates or decide whether school districts, cities, or special districts should tax less. It can only decide the current-year total market value of the property. You cannot appeal only the land value or only the improvement value; your appeal is about the total market value shown on the notice. (saltlakecounty.gov)

Whether you should appeal

Appeal if you can show the county’s January 1 market value is too high. The strongest Salt Lake County evidence is usually one of these: (1) your closing disclosure/settlement statement if you bought the property within one year of January 1, (2) a full professional appraisal with an effective date within one year of January 1, (3) comparable sales within one year of January 1 — the county form says at least three comps are required and up to five are preferred — or (4) a factual error such as wrong square footage, legal description, percent complete, or other physical characteristic that affects value. (saltlakecounty.gov)

Do not appeal just because the tax bill went up. Salt Lake County explains that rates vary by tax area — school district, city, service districts, water, mosquito abatement, and other entities — and tax increases can come from rates even when your market value is unchanged. Start by checking the property record: living area, basement finish, condition, garage, lot size, and classification. If those are wrong, include proof such as photos, plans, appraisals, or closing documents.

Local results are useful but not a promise. The latest BOE annual report available on the county site, for the 2024 board year, says the Board received 4,204 appeals, about 1% of 387,446 assessed parcels; 15.7% of all appeals resulted in adjustments, and the average adjustment rate per appeal was 1.21%. The same report says the average processing time from receipt to mailed decision was 114 days in 2024, with residential appeals averaging about 118 days. (saltlakecounty.gov)

Step-by-step how to file

1. Read the Notice of Valuation and Tax Change. Find the parcel number, market value, property type, taxable value, and the “Right to Appeal” deadline. For a primary residence, confirm the taxable value is 55% of market value; Utah’s primary residential exemption removes 45% of qualifying residential value from taxation.

2. Choose your evidence. Salt Lake County says evidence is required or the appeal may be returned for more information or dismissed. MLS comps should be similar in location, age, size, quality, condition, and date; the county prefers the “Residential Full Report” / listing full print format.

3. Use the right form. The paper form is BE-01.2025 Appeal to the Salt Lake County Board of Equalization Real Property. If you appeal online, use the county’s Online Property Tax Appeal portal. If you are filing after a final county decision, the form is State Tax Commission Appeal Form TC-194; after a dismissal, the county lists TC-194a. Commercial appeals have extra forms such as a confidentiality agreement and owner authorization, but most owner-occupied homeowners will not need those. (saltlakecounty.gov)

4. File in only one method. Salt Lake County lists four filing methods: online portal; email the appeal form and evidence to propertytaxappeals@saltlakecounty.gov; mail to Office of the Salt Lake County Auditor / Property Tax Division, 2001 South State Street, Suite N3-300, PO Box 144575, Salt Lake City, UT 84114-4575; or deliver in person to 2001 South State Street, Suite N3-300, Salt Lake City, UT 84114-4575. The Government Center North Building lobby also has a secure appeal drop box, and room N3-300 can provide a receipt if you hand-deliver. (saltlakecounty.gov)

5. Fee. The county appeal instructions and BE-01 form list required evidence and filing methods but do not state any filing fee for a residential BOE valuation appeal. If you hire an appraiser or agent, that is your cost, not a county filing fee.

What happens after

The proper appeal authority is the Salt Lake County Board of Equalization. The county states that the County Council is the Board of Equalization, the Board sets policy and makes final decisions based on its own findings or findings of appointed hearing officers, and the County Auditor serves as Clerk of the Board of Equalization. (saltlakecounty.gov)

The process starts with screening by Council Tax Administration. If your evidence is insufficient, you may receive an “intent to dismiss” and be given a chance to respond. Then the Assessor reviews the evidence and may recommend an adjustment. If you accept the recommendation, the case can be resolved by stipulation. If not, it can move to a hearing. (saltlakecounty.gov)

A hearing is not a courtroom trial. Salt Lake County says an officer of Tax Administration conducts the hearing, takes oral testimony if you appear, reviews your market-value evidence and the Assessor’s evidence, and writes a recommended market value. The form lets homeowners waive appearance for a written-only review, or choose a phone hearing or virtual hearing; if no hearing option is selected, the county says a phone hearing will be scheduled if a phone number is provided, otherwise the appeal may be treated as a waiver. (saltlakecounty.gov)

The Board may raise, lower, or leave the value unchanged. Salt Lake County’s timeline says, unless extended by the State Tax Commission, appeals are reviewed and a recommendation is made through review or hearing around October 1; however, recent local processing data shows decisions can take months. Pay your taxes by the normal due date even if the appeal is pending; the form says refunds are issued only after a final, unappealable decision. If you disagree with the final BOE decision, you generally have 30 days from receipt to appeal to the Utah State Tax Commission. (saltlakecounty.gov)

Local tips

Check the 45% primary residential exemption before appealing value. Salt Lake County says the primary residential exemption gives a 45% decrease in property tax for a dwelling used as a primary domicile for at least 183 consecutive days, and only one exemption may be claimed per household in Utah. If your notice does not show taxable value at 55% of market value and the home is your primary residence, call the Assessor before filing a value appeal. (saltlakecounty.gov)

Also check relief programs. These are separate from a valuation appeal. Salt Lake County Treasurer programs include Circuit Breaker relief for age 67+ or surviving spouses with household income up to $44,221 in 2026, veteran relief, hardship relief, indigent relief, blind relief, and senior deferral for age 75+ homeowners who meet requirements. The general tax-relief application deadline is September 1. (saltlakecounty.gov)

Savings example using a Salt Lake County rate: tax rates differ by tax area. A 2026 Salt Lake County example notice for a Sandy/Canyons-area property shows a total tax rate of 0.009556. If a primary-residence homeowner proves the market value should be reduced by $50,000, the taxable-value reduction is $50,000 × 55% = $27,500. Estimated annual tax savings: $27,500 × 0.009556 = $262.79. If your notice’s total tax rate is 0.008500, the same $50,000 reduction saves $233.75; if it is 0.010000, it saves $275. Use the total tax rate on your own notice for the final math. (saltlakecounty.gov)
