Cost of Living and Property Taxes in South Jordan: The 45% Exemption Explained

Almost every buyer moving to Utah from another state gets this wrong, and it's an expensive thing to get wrong in either direction. So let's start with the sentence that matters:

Utah exempts 45% of a primary residence's fair market value from property tax. You pay tax on 55% of the value.

People often flip that and call it "the 55% exemption." It isn't. The exemption is 45%. The 55% is what's left over and taxable. Both numbers appear on your notice, which is why the confusion persists.

How the exemption works

The Utah State Tax Commission puts it plainly: the taxable value of your property will be 55% of the market value, reflecting the 45% exemption, and most residences in Utah receive it. Your Valuation Notice, which arrives at the end of July, or your Tax Notice, which arrives around the start of November, will indicate whether you're getting it.

The legal basis: the Utah Constitution allows county assessors to exempt 45% of the fair market value of residential property and up to one acre of land. State code 59-2-103 provides the 45% residential exemption on primary residences, and Utah code defines a primary residence as a home that serves as the occupant's primary domicile for at least 183 consecutive days in a year. The owner, the owner's spouse, another family member, or a tenant may occupy the residence.

A few consequences that matter to out-of-state buyers:

• Second homes and vacation homes don't get it. Secondary homes are taxed at 100 percent of market value. If you're buying a Utah property you won't live in, run the math at roughly double the tax of a comparable primary residence.
• One per household, statewide. Only one household may claim the exemption within the state of Utah. Married couples living apart cannot claim two exemptions unless they are legally separated.
• A tenant-occupied rental can still qualify if the occupancy test is met, but an application to the county is usually required in that circumstance.
• It's not new. The exemption has existed since 1982 and was raised to 45% in 1995.

How to check you're actually getting it

This is the two-minute audit I ask every client to do after they close.

Pull out your Valuation Notice or Tax Notice and compare two lines. If the exemption is applied, the taxable value should be roughly 55% of market value. If the taxable value looks like 100% of market value, the home may not be receiving the primary residential exemption. Don't assume the notice will say "homestead" — Utah counties use different terms.

If it isn't applied, the fix usually runs through a declaration form. If your mailing address differs from your physical address, Utah law requires you to submit a Residential Property Declaration, and it must be returned within 90 days of the letter's date — failure to do so results in losing the exemption and a significant increase in property tax. All vested property owners must sign it. County assessors are required to verify and correctly classify all residential properties as primary or secondary.

That last point catches relocating buyers constantly. You close in September, your mail still forwards to your old state, and the county's records don't line up. Open county mail.

What a South Jordan bill actually looks like

Utah property tax is the sum of rates from overlapping taxing entities — the county, the city, the school district, and various special service districts — applied to that 55% taxable value. Your specific combination is called a tax area, and Salt Lake County contains more than 360 separate tax districts, so there is no single "South Jordan rate."

For scale, the city's own slice is small. The Salt Lake County Auditor's 2025 certified property tax rate for South Jordan City was 0.001313. The school district levy is typically the largest single line on a Utah tax bill.

A worked example, using effective rate — meaning tax as a share of market value, with the 45% exemption already baked in:

A $600,000 primary residence has a taxable value of $330,000 after the exemption. South Jordan's median effective property tax rate is about 0.56% of value, against a Utah state median of 0.55% and a national median of 1.02%. That works out to roughly $3,300–$3,400 a year, or about $280 a month in escrow.

Treat that as a planning number, not a quote. Rates reset annually through Utah's certified tax rate process, and your tax area may sit above or below the city median. The exact figure is on your November tax notice.

South Jordan homeowners who believe their assessed value is too high can file a formal appeal with the assessor — deadlines are set annually, so confirm the current one with Salt Lake County rather than relying on a date in a blog post.

The rest of the cost picture

Income tax. Utah has a flat rate with no local income taxes layered on top. The Legislature has cut it in five consecutive sessions, from 4.95% down to 4.45%; SB 60 in 2026 was the most recent cut, lowering the rate from 4.50% to 4.45%. Utahns filing jointly with income below $90,000 qualify for a state tax credit that effectively eliminates state income tax on Social Security benefits.

Sales tax. The combined sales and use tax rate in South Jordan is 7.45%, on a 4.85% state base — the same combined rate as Sandy, West Jordan, Taylorsville and West Valley City, and lower than Salt Lake City's 8.45%.

HOA, if you're in Daybreak. The base Daybreak association fee is $144.50 per month for 2026, with additional sub-association dues for townhomes and condos covering things like snow pushing, yard care, some exterior maintenance and building insurance. This is a real monthly line item, not a rounding error, and it belongs in your affordability math alongside taxes and insurance.

Housing, the biggest number of all. The median single-family home in Salt Lake County hit $645,000 in the second quarter of 2026, a record, and a Salt Lake Board of Realtors study found buyers need to earn roughly $187,000 a year to afford a median-priced single-family home countywide. Utah's tax structure is genuinely light compared with much of the country. Its housing is not.

Frequently asked questions

Does Utah have a homestead exemption?
Functionally, yes — it's called the primary residential exemption. It reduces your taxable value to 55% of market value, reflecting a 45% exemption.

Is the exemption 45% or 55%?
The exemption is 45%. You pay property tax on 55% of the home's fair market value.

Do I have to apply for it?
In most counties, the exemption is generally assumed to apply to existing residential property, so if you bought a house that the previous owner used as a primary residence, the exemption came with it. But a declaration may be required when title transfers or when your addresses don't match, and it must be returned within 90 days.

What if I rent the house out?
It can still qualify if a tenant occupies it for the required period, but an application to the county is usually required. Short-term and transient rentals don't qualify.

What's the sales tax in South Jordan?
7.45% combined.

What's Utah's income tax rate?
