How Does Utah’s 45% Primary Residence Property Tax Exemption Work?
People relocating to Utah are often surprised to learn that a qualifying primary residence is not taxed on its full market value.
Utah provides a 45% primary residential exemption. This means property taxes are generally calculated using only 55% of the home’s fair market value.
This is not a special benefit limited to seniors, veterans, first-time buyers, or lower-income households. It is a broad residential property-tax provision for qualifying primary residences.
But here is where homeowners need to be careful:
Do not assume the exemption is being applied correctly simply because the property is a home.
Most Davis County residences currently receive the exemption by default. However, an ownership change, a different mailing address, rental use, short-term rental activity, additional acreage, or a missed county declaration can affect the property’s classification.
The goal is not to become a property-tax expert. The goal is to understand what classification you are receiving, why you qualify, and what action the county may require.
The Direct Answer
Under Utah Code Section 59-2-103, qualifying residential property receives a 45% reduction in taxable market value.
The property-tax rate is then applied to the remaining 55% of the home’s fair market value.
For example:
Fair market value: $600,000
Residential exemption: $270,000
Remaining taxable value: $330,000
The applicable property-tax rate would be applied to the $330,000 taxable value rather than the full $600,000 market value.
This is not a 45% discount on the purchase price.
It is not a $270,000 tax deduction.
It is not a refund check.
It is a reduction in the property value used to calculate the tax bill. The Utah State Tax Commission’s residential-property guide explains the difference between fair market value and taxable value.
Why This Matters to People Moving to Utah
An out-of-state buyer may estimate Utah property taxes by multiplying the home’s entire purchase price by a general tax rate.
That can produce a misleading estimate.
For a qualifying primary residence, Utah generally calculates taxable value using 55% of the property’s fair market value. The final tax bill still depends on the county’s assessed value and the combined rates imposed by local taxing entities.
This distinction can affect:
Estimated annual property taxes
Monthly mortgage escrow
Debt-to-income calculations
Comparisons between Utah and another state
The amount collected by a lender at closing
The buyer’s complete monthly housing expense
Property taxes are only one part of the payment. Buyers should also account for homeowners insurance, mortgage insurance, HOA dues, utilities, repairs, and maintenance.
Our guide to what monthly payment buyers should expect in Davis County explains why the complete cost of ownership matters more than the principal-and-interest payment shown in an online calculator.
Relocating buyers comparing communities should also review Salt Lake City versus Davis County before deciding where the payment, commute, housing style, and lifestyle fit best.
Who Qualifies for Utah’s Primary Residential Exemption?
According to the Davis County Assessor’s primary-residence guidance, residential property generally qualifies when it serves as the primary residence of an owner or tenant for at least 183 consecutive days during the calendar year.
There are two common qualifying situations.
Owner-occupied primary residence
The owner or the owner’s household occupies the home as its primary residence for the required period.
Long-term tenant-occupied residence
A tenant occupies the property as that tenant’s primary residence for the required period.
This means the exemption is not limited strictly to owner-occupied homes. A traditional long-term rental may qualify when it serves as the tenant’s primary residence.
However, the exemption is generally limited to one owner-occupied primary residence per household. The Utah State Tax Commission explains that the exemption can apply whether the resident is an owner or a tenant, but one household cannot normally claim multiple homes as its primary residence.
What Properties Usually Do Not Qualify?
Properties that generally do not qualify include:
Second homes
Vacation homes
Cabins used seasonally
Vacant homes
Vacant land
Commercial properties
Timeshares
Transient lodging
Short-term rentals
Condominiums operated through rental pools
Davis County specifically states that vacant homes and short-term rentals such as Airbnb and VRBO do not qualify for the exemption.
The Utah State Tax Commission’s primary residential exemption page also explains that transient residential use and condominiums used in rental pools are not considered qualifying primary residences.
That creates an important distinction:
A home occupied by one long-term tenant as that tenant’s primary residence may qualify.
A home repeatedly rented to short-term guests generally does not.
Does the Exemption Apply to the Entire Property?
Not always.
The exemption can apply to the residence and up to the first acre of land used with it.
Land beyond the first acre is generally taxed at 100% of fair market value, even when the additional land is used as part of the homeowner’s property.
This can materially affect the tax calculation for:
Horse properties
Estate homes
Small farms
Rural residences
Homes with development ground
Properties containing several acres
A buyer purchasing a five-acre home site should not assume all five acres receive the 45% residential exemption.
The first-acre limitation is explained in both Utah Code Section 59-2-103 and the Davis County primary-residence guidance.
Is the Exemption Automatic in Davis County?
It is commonly granted by default, but homeowners should still verify it.
Davis County states that it currently assumes most homes are built and purchased for primary residential occupancy. The county therefore grants the exemption to most homes unless it discovers that a property is not being used as a qualifying primary residence.
The exemption may already be attached to a home that was used as a primary residence by the previous owner.
However, the county may request verification when:
Ownership changes
The mailing address differs from the property address
The property was previously classified as secondary
Driver’s-license or voter-registration information does not match
The property becomes tenant-occupied
The county believes the home may be a second residence
The use of the home changes
The county sends a Residential Property Declaration
A buyer should verify the classification after closing rather than assuming everything transferred correctly.
How Can I Check Whether My Davis County Home Receives the Exemption?
There are three practical ways to check.
1. Review the property classification
Open the Davis County Property Search, launch Property Search 2.0, and search by the property address or parcel number.
Open the parcel details and look for the classification:
Primary generally means the exemption is being applied.
Secondary generally means it is not.
2. Compare market value and taxable value
Your valuation notice or property-tax notice should show both numbers.
If the full exemption is being applied, taxable value should generally equal 55% of the qualifying market value.
For example:
Market value: $600,000
Taxable value: $330,000
If market value and taxable value are identical, the property may be taxed without the residential exemption.
3. Read the property description on the tax notice
The notice may describe the property as:
Primary Land and Buildings
Secondary Land and Buildings
Davis County outlines all three verification methods on its primary-residence information page.
How Do I Apply for the Exemption in Davis County?
When a qualifying property is not receiving the exemption, the owner should contact the Davis County Assessor and ask what application or declaration is currently required.
Step 1: Confirm the property qualifies
Determine whether the home is or will be occupied as the owner’s or a tenant’s primary residence for at least 183 consecutive days.
Step 2: Obtain the current application
Utah currently uses the TC-473A Application for Residential Property Exemption.
The form must be submitted to the county where the property is located.
Because forms and procedures can change, use the current form from the Utah State Tax Commission or obtain one directly from the Davis County Assessor. Do not rely on an old form saved from a previous transaction.
Step 3: Gather supporting evidence
The current TC-473A form requests at least three forms of evidence for an owner-occupied application.
Examples include:
Driver’s license
Vehicle registration
Voter registration
Utility bill
Most recent state or federal income-tax return
When the property is the primary residence of a tenant, the current application states that a copy of the lease agreement is required.
The county may request additional evidence when the initial documents do not clearly establish eligibility.
Step 4: Submit the application to Davis County

What If Davis County Sends Me a Residential Property Declaration?
Respond to it immediately.
Davis County may send a Residential Property Declaration when:
The property changes ownership.
The owner’s mailing address differs from the physical address.
The county receives information suggesting the classification should be reviewed.
The current Davis County Residential Property Declaration portal states that the declaration is required only when the owner has received a letter from the Assessor’s Office.
The portal states that the form must be completed within 90 days from the date on the letter. Failure to file can result in the loss of the primary residential exemption and a significant property-tax increase.
Follow the exact instructions and deadline printed on your letter. Do not wait until the end of the stated period.
This can become a problem for a relocating buyer who:
Purchases a Davis County home.
Continues receiving mail at an out-of-state address.
Misses the county’s declaration.
Fails to respond.
Later discovers that the home was classified as secondary.
Forward your mail, update your contact information, and open every county notice after closing.
Ignoring important documents is one of the preventable issues discussed in What Are the Biggest Mistakes Utah Homebuyers Make?
Important Application Change Beginning January 1, 2027
The application process changes on January 1, 2027.
Under the Utah Code provisions effective January 1, 2027, an owner must file an application before the county applies the exemption when:
The property was ineligible during the previous calendar year.
An ownership interest in the property changes.
The county determines there is reason to believe the property no longer qualifies.
This means buyers purchasing property in 2027 should not assume the previous owner’s residential exemption will automatically continue without action.
Before closing, ask:
What application will be required?
Who is responsible for submitting it?
What is the deadline?
What proof of occupancy will be required?
Will the lender’s escrow estimate reflect the qualifying classification?
Rules that apply to a 2026 closing may not be the same rules that apply to a 2027 closing.
Does Claiming the Exemption Affect Utah Income-Tax Residency?
It can become part of the residency analysis.
Under Utah Code Section 59-2-103.5, claiming the residential exemption for an owner’s Utah primary residence can be considered when determining whether the owner and the owner’s spouse are domiciled in Utah for income-tax purposes.
Davis County describes this as a rebuttable presumption of Utah domicile.
For a family permanently relocating to Utah, that may match reality.
But someone who owns homes, operates businesses, earns income, votes, registers vehicles, or claims residency in multiple states should consult a qualified tax professional.
Do not make conflicting primary-residence claims without understanding the consequences.
What Happens When the Property Stops Qualifying?
A property owner should notify the county when a property no longer qualifies.
Examples include:
The home becomes a vacation property.
The owner moves away and leaves it vacant.
A long-term tenant leaves and is not replaced.
The property is converted to short-term rental use.
The property becomes commercial.
The household establishes a different home as its Utah primary residence.
Utah Code Section 59-2-103.5 outlines the owner’s obligation to report when a property no longer qualifies, subject to an exception when the owner moves directly from one qualifying Utah primary residence to another.
Continuing to receive an exemption after the property no longer qualifies can lead to corrected assessments and additional taxes.
Common Mistakes Homeowners Make
Assuming the lender’s property-tax estimate is correct
A lender may begin with the prior tax bill, a general estimate, or the home’s current classification.
Ask how the tax figure was calculated and whether the estimate assumes primary or secondary classification.
Confusing market value with taxable value
The exemption does not determine the county’s fair market value.
The assessor establishes market value first. The qualifying exemption is then used to determine taxable value.
Ignoring a declaration mailed to an old address
A missed declaration can cause the exemption to be removed.
Assuming every residential property qualifies
A second home, vacant home, vacation rental, short-term rental, or transient property may not qualify.
Forgetting the first-acre limit
The residence and first acre may qualify while additional land is taxed at full market value.
Claiming two owner-occupied primary residences
A household is generally limited to one owner-occupied Utah primary residence.
Using an old application
Forms, documentation requirements, and deadlines can change. Always use the current county or state form.
What Buyers Should Check Before Closing
Before purchasing a Davis County home:
Review the parcel’s current classification.
Confirm whether it is listed as primary or secondary.
Compare the market value and taxable value.
Ask how the current owner uses the property.
Determine whether the parcel exceeds one acre.
Estimate taxes using the expected post-purchase classification.
Ask the lender how property taxes were calculated.
Ask whether a new application will be required.
Watch for county declarations after closing.
Update address and residency records when appropriate.
Keep copies of occupancy documents.
Contact the Davis County Assessor when something looks incorrect.
These questions should be part of a broader due-diligence process. Our guide to what buyers should know before purchasing a home in Davis County explains other financial, property-condition, location, and contract issues that deserve attention before closing.
The Bottom Line
Utah’s primary residential exemption is a significant homeowner benefit, but it is best understood as a reduction in taxable value.
A qualifying home with a $600,000 fair market value would generally have a taxable value of $330,000 before the local property-tax rate is applied.
Most Davis County homes currently receive the exemption by default. That does not remove the homeowner’s responsibility to verify the classification, respond to county notices, and report changes in use.
Beginning January 1, 2027, an ownership change will trigger an application requirement under the revised Utah law.
The tax system does not reward guessing.
Check the parcel.
Read the notices.
Keep your records.
Ask questions when the numbers do not look right.

Frequently Asked Questions About Utah’s 45% Primary Residence Exemption
What is Utah’s 45% primary residence property tax exemption?
It is a reduction in the taxable value of qualifying residential property. The exemption removes 45% of the property’s qualifying fair market value, leaving 55% subject to the applicable local property-tax rate.
Does the exemption lower my property-tax bill by exactly 45%?
Not necessarily. It reduces the taxable value by 45%. The final bill depends on the county’s assessed fair market value, qualifying acreage, and the combined property-tax rate.
How long must I live in a Utah home to qualify?
Davis County generally requires the property to be occupied as the primary residence of an owner or tenant for at least 183 consecutive days during the calendar year.
Do long-term rental properties qualify?
They may. A property can qualify when it serves as a tenant’s primary residence for the required period. The owner may need to provide a declaration and current lease agreement.
Does an Airbnb qualify for the exemption?
Short-term and transient rentals generally do not qualify because they are not being used as one household’s primary residence for the required period.
Is the exemption automatically applied in Davis County?
Davis County currently grants the exemption to most homes by default, but the county may require verification or an application when ownership, mailing information, occupancy, or property use changes.
Beginning January 1, 2027, Utah law requires an application when an ownership interest changes.
How can I tell whether my home receives the exemption?
Review the Davis County parcel record or tax notice. A qualifying property should generally be classified as Primary, and the taxable value should ordinarily equal 55% of the qualifying market value.
Does the exemption apply to more than one acre?
No more than the first acre used with each qualifying residence receives the exemption. Additional acreage is generally taxed at 100% of fair market value.
Can I claim the exemption on two Utah homes?
A household is generally limited to one owner-occupied primary residence. A separate rental property may qualify when it serves as a tenant’s primary residence.
What should I do if I receive a Residential Property Declaration?
Complete it immediately and follow the deadline stated in the county’s letter. Davis County’s current portal states that failure to submit the declaration within 90 days can result in loss of the exemption.
How do I apply if my Davis County home is classified as secondary?
Contact the Davis County Assessor and ask whether you should submit the current TC-473A application or another county form. Be prepared to provide evidence of occupancy and residency.
Will application rules change in 2027?
Yes. Effective January 1, 2027, Utah law requires an application when an ownership interest changes, when the property was previously ineligible, or when the county has reason to believe it no longer qualifies.
Does the exemption affect Utah income-tax residency?
Claiming an owner-occupied Utah residential exemption can be considered when determining whether the owner is domiciled in Utah. People with tax or residency ties to multiple states should seek professional tax advice.
