Wilson, Williamson, Sumner, and Rutherford Counties each offer a property tax freeze for qualifying homeowners once they enroll — but "freeze" doesn't mean a low number gets fixed for you. It means whatever your bill happens to be the year you successfully file gets locked in place. File the year you close, and you freeze at your entry-level assessment. Wait a few years while the county's next reassessment cycle catches up to a hot market, and you freeze at a considerably higher number instead.

A buyer who qualifies by age and income the day they close but doesn't file the paperwork for two or three years isn't just missing out on savings during that gap — they're likely to end up freezing at a meaningfully higher assessed value than if they'd filed immediately, since Middle Tennessee's reassessment cycles have generally moved values up, not down.
Eligibility (age 65+, income under the county's threshold) is necessary but not sufficient — the freeze only takes effect once you file the application with your county Trustee's office, and it locks whatever the assessed value is at that moment. Confirm your county's specific application window and file as close to your qualifying date as the county allows, rather than treating eligibility itself as the trigger.

| County | 2026 income limit | Communities |
|---|---|---|
| Williamson | $67,460 (highest in TN) | Del Webb Southern Springs |
| Rutherford | $61,920 | StoneBridge |
| Wilson | $63,470 | Lake Providence, Barton Village, Groves Reserve |
| Sumner | $47,000 | Durham Farms |
The county-to-county income limit spread is also worth noting on its own: Sumner County's $47,000 threshold is meaningfully tighter than Williamson County's $67,460, meaning the same household income could qualify for the freeze at Durham Farms in Sumner County's neighboring communities but miss the cutoff in Williamson County entirely, or vice versa. None of these thresholds are fixed forever — confirm the current year's limit with the relevant county Trustee before assuming last year's number still applies.
The honest way to shop this market: if you expect to qualify for the property tax freeze at any point, file with your county Trustee as early as the rules allow rather than waiting — the freeze rewards early filing with a lower locked-in number, and there's no benefit to delaying once you're eligible.
