Utah's Age 66 Circuit Breaker (Form TC-90CY for Homeowners, TC-90CB for Renters): Combined Abatement of Up to $1,312 Plus a 20%-of-Fair-Market-Value Homeowner Tax Credit Layer

Updated April 2026

Utah's Circuit Breaker program is the primary senior property tax mechanism, with a relatively unusual age threshold of 66 (not 65). The program splits administratively into two forms: Form TC-90CY for homeowners and Form TC-90CB for renters. For homeowners, the credit combines a Low Income Abatement (up to $1,312 in 2025) with an additional tax credit equal to property tax on 20% of fair market value. The 2024 income threshold for the standard program was under $42,623; more recent 2025 limits adjust annually. A separate CB75+ extension serves homeowners 75 and older with a higher income cap (around $85,246 in 2025), recognizing that older retirees often have somewhat higher income from required minimum distributions while still needing tax relief.

Eligibility for the Standard Circuit Breaker

Age 66 or older on or before December 31 of the application year, OR an unmarried surviving spouse of a qualifying applicant (any age).
Total household income below the annual income threshold (under $42,623 for the 2024 cycle; adjusts annually).
Owner-occupant of the homestead (or qualifying renter for TC-90CB).
Utah resident.

Mechanic for homeowners: the Circuit Breaker provides a Low Income Abatement of up to $1,312 in tax relief, layered with the additional Homeowner's Tax Credit equal to property tax on 20% of the home's fair market value. So on a $250,000 home, the additional credit covers tax on $50,000 of value (20% of $250K) — a meaningful supplement to the abatement's flat-dollar amount.

Is your Utah fair market value defensible?

The Homeowner's Tax Credit is computed on 20% of your home's fair market value. If the FMV is too high, both the layer of relief and the unprotected portion grow proportionally — but the unprotected portion grows faster. An assessment review reduces the unprotected base.

CB75+: The Extension for Older Seniors

Utah recognized that the standard Circuit Breaker's income cap can exclude many retirees in their late 70s and 80s whose income has risen modestly above the threshold (often due to required minimum distributions from retirement accounts). The CB75+ extension provides Circuit Breaker eligibility for homeowners 75 and older at a higher income cap — around $85,246 in 2025, roughly double the standard cap. The extension uses the same forms and produces the same relief structure; it only changes the income eligibility threshold.

No Senior Assessment Freeze in Utah

Utah does not run a senior-specific assessment freeze. Reassessment occurs on a 5-year cycle in most counties, with annual updates between full reassessments. Senior protection is the Circuit Breaker abatement and credit; there's no mechanism to lock the assessed value of a senior's home.

Frequently Asked Questions

Why is Utah's Circuit Breaker age 66 instead of 65?

Utah is unusual in that respect — most states use age 65 as the eligibility threshold for senior property tax programs. Utah's 66 threshold tracks federal Social Security full-retirement-age framing (which has shifted from 65 toward 67 over decades) more closely than most state property tax statutes. Practically, this means Utah seniors who turn 65 must wait one additional year before claiming Circuit Breaker relief that they'd be eligible for in a neighboring state (Idaho, Colorado, etc.). The age threshold is statutory and not currently subject to legislative modification proposals.

My Utah household income is $60,000 and I'm 78. Do I qualify for any Circuit Breaker relief?

Likely yes, under the CB75+ extension. The standard Circuit Breaker income cap (around $42,623 for 2024 income) excludes you, but the CB75+ extension for homeowners 75 and older has a much higher cap of approximately $85,246 in 2025. At $60,000 you're well under the CB75+ cap. File Form TC-90CY with Utah State Tax Commission; the form routes you into either the standard or CB75+ track based on age and income. Required documentation: proof of age (age 78 puts you firmly in the 75+ tier), prior-year income documentation, and proof of homestead ownership.

Can the Utah Circuit Breaker abatement and the Homeowner's Tax Credit both apply at once?

Yes — both layers stack. The Low Income Abatement reduces your tax bill by up to $1,312 (a flat-dollar amount based on your tier). The Homeowner's Tax Credit additionally covers property tax computed on 20% of your home's fair market value. So a qualifying senior on a $250,000 home receives the abatement of up to $1,312 PLUS the credit covering tax on $50,000 of value (20% of $250K). The combined relief can substantially exceed what either layer produces alone, especially for moderate-income seniors in higher-cost-of-living Utah counties (Salt Lake, Davis, Utah, Summit).
