🏠Uncapped: The Property Tax Question

Tennessee likes to see itself as a low-tax state. No income tax. A place where you work, buy a home, and the government doesn’t hover. That picture still mostly fits. Property taxes, though, have started to test the margins.

Property tax policy is back on the table, even in Williamson County. Nothing here has gone off the rails, but what’s happening elsewhere in Tennessee should get everyone’s attention. And once the genie’s out of the bottle, it doesn’t readily crawl back in on command.

The Beacon Center of Tennessee is doing most of the pushing here, putting a straightforward question in front of lawmakers this session: should local property taxes have limits, and should voters have to approve increases beyond them? It’s not a radical idea — it’s how many other states already operate, with caps tied to growth or inflation and a public vote if government wants more. Which sounds reasonable enough.

The biggest countywide move in recent memory was the 2021 property tax increase. It followed years of rapid growth, pandemic revenue hits, and the loss of Hall tax dollars. Schools were swelling, courts were jammed, and the cost of roads, public safety, and staffing was climbing across the board. Residents didn’t have to like the decision — and plenty didn’t — but thankfully, it wasn’t the first domino in an endless tax tumble.

From a municipal standpoint, we see bigger hikes, and Nolensville is a useful example. Last year, the town adopted a five-cent increase — around a 17% bump — in its rate. On paper, the overall amount remains low. In real life, Nolensville, which has ballooned more than sixfold in the last decade, is now ponying up serious dollars for police and fire staffing, sewer capacity, road fixes, and parks that don’t collapse after one soccer season. The plain reality remains: real growth costs real money. The question is who gets to decide when it’s time to reach deeper… and who gets veto power.

This is where Beacon’s argument starts to land. Tennessee is one of only a handful of states with no statewide limit on how fast local property tax collections can grow. Counties and cities set their own rates. There’s no automatic cap, no built-in pause, and no requirement that voters approve increases beyond a certain point. If the votes are there on the local governing body, the increase happens. And sometimes it happens big: Davidson County jumped roughly 34% in a single pandemic-era vote, while Mt. Juliet racked up increases north of 150% over just a few years. That’s the kind of math you feel.

Beacon’s argument isn’t just theory. In a place like Williamson, where home values are high, even a modest rate change turns into a major mailbox moment. The average home here is about $900,000. That kind of rate move doesn’t feel modest when you’re paying taxes on valuations that start with a nine.

And the impact is real. Retirees on fixed incomes? Oof. Families scraping for childcare or college? Double oof. Anyone not swimming in cash? Welcome to the pain party, friends — where small change adds up, and minor arithmetic becomes a real obstacle.

So the question isn’t whether Williamson County has gone full spendaholic. It hasn’t. The question is whether it’s smarter to talk about guardrails now, while the numbers are still manageable — or later, when they’re already baked into the bill.

We’re very good at choosing later. Later always shows up on time, with interest. But capping spending feels a lot like buckling your seatbelt; it’s an inconvenience… that is, until you crash.
