Tennessee has no state property tax today, but the legislature could create one; this slams that door for good. It is a tax-limit measure with almost no immediate effect and a real long-term one — it takes a revenue tool permanently off the table. If you believe the safest tax is the one government can't reach for, this is your vote. If you'd rather not bind a future legislature's hands in a genuine crisis, that's the honest counter. Either way, your county tax bill is untouched.
