In most states, your property's assessed value can increase every year — and your tax bill rises with it. But a handful of states offer programs that let qualifying homeowners lock their assessed value in place, so it can't rise no matter what the market does.
These are called assessment freezes, and they can save long-term homeowners significant money over time.
How an Assessment Freeze Works
When you qualify for a freeze, your property's assessed value is locked at the level it was when you enrolled. Even if your home's market value increases by 30% over the next five years, your taxable assessment stays the same.
The freeze doesn't affect your mill rate — if taxing authorities raise their levies, your bill can still go up slightly. But it eliminates the compounding effect of rising assessments, which in appreciating markets is often the bigger driver of tax increases.
When you sell the home or no longer qualify, the freeze ends and the assessment is updated to current market value.
States with Assessment Freeze Programs
Illinois: The Senior Citizens Assessment Freeze Homestead Exemption is one of the most generous in the country. Homeowners 65 and older with household income below $65,000 can freeze their equalized assessed value indefinitely. The freeze applies to all property taxes, not just a portion.
Texas: Homeowners 65 and older with a homestead exemption get a freeze on their school district taxes. The actual dollar amount of school taxes paid cannot increase as long as they stay in the home. This is automatic once you reach 65 and have an active homestead exemption — no separate application needed.
Oklahoma: The Senior Valuation Freeze locks the fair cash value of your home if you're 65 or older with household income below a threshold (currently around $75,000). Once locked, the assessment cannot increase regardless of market conditions.
South Carolina: The Assessable Transfer of Interest provision is unique — it limits assessment increases to 15% over any five-year period for owner-occupied primary residences. It's not a full freeze but significantly limits growth.
Arizona: The Senior Property Valuation Protection Option freezes the limited property value for homeowners 65 and older who meet income and residency requirements. Must be renewed every three years.
New Jersey: The Senior Freeze (Property Tax Reimbursement) program reimburses eligible seniors for increases in property taxes over a base year amount. It functions more like a reimbursement than a true freeze but achieves a similar result.
Washington: Qualifying seniors and disabled homeowners can freeze their assessed value at the level it was when they first qualified. Income limits apply and vary by county.
Who Qualifies
Most freeze programs share a common set of requirements:
- ›Age: Typically 65 and older, though some programs extend to disabled homeowners of any age
- ›Primary residence: Must be your principal home — not a rental or vacation property
- ›Income limits: Most programs cap household income somewhere between $35,000 and $75,000, depending on the state
- ›Residency duration: Some programs require you to have owned and lived in the home for a minimum period, often two to three years
How to Apply
Applications go to your county assessor's office in almost every state. You'll typically need:
- ›Proof of age
- ›Prior year tax returns or other income documentation
- ›Your parcel number or property address
Deadlines matter. Most programs have annual application windows — often in the first quarter of the year. In some states, once you're enrolled you don't need to reapply annually. In others, annual renewal is required.
If Your State Doesn't Have a Freeze
Check what your state does offer. Many states without formal freeze programs still have assessment caps — limits on how much your assessed value can increase in a single year. California's Proposition 13 caps increases at 2% per year. Michigan caps increases at 5% or the inflation rate. Florida's Save Our Homes cap limits increases to 3% per year for homestead properties.
These caps don't freeze your assessment, but they do slow its growth significantly — which has much the same effect over time for long-term owners.
If none of those apply, an annual appeal of your assessment is always an option. It's not as permanent as a freeze, but if your assessment is running ahead of market value, it can produce real savings.
