Why a Freeze Beats an Exemption Over Time
A $50,000 exemption saves you the same amount every year. A freeze compounds: it locks in today's number while everyone else's bills climb with reassessments and rate hikes. For a retiree planning to stay in the home ten or twenty years, a freeze is usually the single most valuable property tax benefit available, and one of the least claimed, because most freezes require an application that nobody sends you.
One crucial distinction before the table. States freeze one of two different things:
- Assessment freezes lock your home's taxable value. Your bill can still rise if tax rates go up.
- Tax-amount freezes lock the actual dollar bill (or reimburse you for any increase). These are stronger: they protect you from rate hikes and reassessments alike.
States That Freeze the Tax Amount
| State | Age | Income limit | How it works |
|---|---|---|---|
| Texas | 65 | None | School district taxes (the largest part of a Texas bill) are frozen as a ceiling the year you qualify: they can fall but never rise unless you improve the home. Counties and cities may adopt their own ceilings. The ceiling even transfers proportionally to a new Texas home |
| New Jersey | 65 | $172,475 (2025, indexed) | The "Senior Freeze" reimburses you each year for the difference between your current bill and your base-year bill. Requires 3+ years in the home; see our NJ relief guide |
| Tennessee | 65 | County-set (2025 floor: $37,530) | Freezes the base tax amount, surviving both rate increases and reappraisals, but only in the 30+ counties and cities that opted in |
| Missouri | 62 | None statewide | The SB 190 credit freezes your bill at its year-of-qualification level, in the ~85 counties that adopted it (including St. Louis, Jackson, Clay, Greene). Annual application with county-set deadlines |
States That Freeze the Assessed Value
| State | Age | Income limit | Notes |
|---|---|---|---|
| Arkansas | 65 | None | Constitutional right: taxable value freezes at the assessment after your 65th birthday. One of the few no-income-test freezes; apply once at the county assessor |
| Oklahoma | 65 | County HUD median income (around $90,000 in 2026 in many counties) | Freezes taxable fair cash value permanently once granted; a surprisingly generous income limit most seniors clear |
| Illinois | 65 | $65,000 (2025), rising to $75,000 in 2026 and $79,000 by 2028 | Freezes equalized assessed value; annual reapplication in most counties. In high-rate Illinois this is worth a lot, but rates can still push bills up |
| Arizona | 65 | ~$46,400 single / $58,000 joint (2025, indexed) | Freezes the limited property value for 3 years at a time, then renew. Requires 2 years in the home |
| Louisiana | 65 | ~$100,000 AGI (indexed; a Nov 2026 ballot measure proposes $150,000) | The "Special Assessment Level" freezes assessed value; lost if you improve the home by more than 25% |
| New Mexico | 65 | ~$40,000-44,000 (varies by county) | Low-income valuation freeze; apply annually for 3 years, then automatic |
| South Dakota | 65 | ~$56,600 single / $66,900 household (2025) | Assessment freeze for elderly and disabled; home value cap applies; apply by April 1 |
| Washington | 61 | County-tied (e.g., $84,000 King County) | The senior exemption program also freezes your taxable value at the first qualifying year, on top of exempting part of the levies |
Caps That Aren't Senior Freezes (But Help)
Don't confuse senior freezes with all-homeowner assessment caps: California's Prop 13 (2%/year) and Florida's Save Our Homes (3%/year) limit growth for every homesteader regardless of age, and Georgia's new floating homestead exemption caps assessed-value growth at inflation statewide. If you live in one of these states, you already have partial freeze protection; the senior programs stack on top where they exist. See our Prop 13 guide for how acquisition-based assessment works.
The Fine Print That Matters
- Freezes don't apply retroactively. Your bill freezes at the level of the year you qualify and apply. Every year you delay applying is a permanently higher base. If you turned 65 recently, apply now.
- Improvements break the freeze (partially). Add a room and the new value is added on top of the frozen base in most states; Louisiana cancels the freeze entirely for improvements over 25% of value.
- Income limits are checked, and indexed. Most limits adjust annually. If you were over the limit once, check again; Illinois' limit is jumping by $10,000 in 2026.
- Some freezes need annual renewal (Illinois, Missouri, South Dakota, New Mexico initially), and missing a year can cost you the base. Put it on the calendar.
- Moving resets everything, except in Texas, where the school-tax ceiling transfers as a percentage to your next Texas homestead.
Bottom Line
If you're 65 or older (61 in Washington, 62 in Missouri's counties) and plan to stay put, check the tables above for your state and call the county assessor this week; every year unclaimed is a permanently higher frozen base. If your state offers no freeze, look at senior exemptions and deferral programs instead, and remember a freeze doesn't make appealing pointless: a successful assessment appeal before you freeze locks in a lower base forever.
