Williamson County, TN property tax: 2026 rates, bills and relief

Williamson County property tax at a glance

Estimate your Williamson County property tax bill

Tax year 2026 rates (Williamson County and city 2026 rate tables). Tennessee assesses homes at 25% of appraised value. An estimate, not a tax bill: confirm the jurisdiction on the parcel record and check with the Williamson County Trustee or a CPA.

The FSSD line decides most of your Franklin property tax

Two Franklin houses at the same price can be $1,546 a year apart in tax. Inside city limits, a home in the Franklin Special School District pays $2.2433 per $100 assessed; one outside it pays $1.566. On the $913,277 typical home that's $5,122 against $3,575.

That gap widened this year. The FSSD general fund levy rose from 43.23 to 61.23 cents, so the Franklin plus FSSD rate went from $2.0633 to $2.2433 and the typical bill rose by about $411. If you're choosing between two Franklin neighborhoods, look up the FSSD side of each on the FSSD district map before you compare anything else. The guide to Franklin's two school systems explains what the levy pays for.

2026 property tax rates in Williamson County

Rates are the combined county, city and FSSD figures from the Williamson County Trustee's 2026 rate sheet. Maury County's side of Spring Hill isn't listed: Maury reappraised in 2026, so check its rate with the Maury County Trustee.

How Williamson County property tax is calculated

The Assessor of Property sets the appraised value, the state assesses residential property at 25% of it, and the combined rate applies per $100 of that assessed value.

Example property tax bill on a $913,277 Franklin home

Assessed value: $913,277 × 25% = $228,319. Outside FSSD: $228,319 × $1.566 ÷ 100 = $3,575 a year, or about $298 a month in escrow. Inside FSSD: $228,319 × $2.2433 ÷ 100 = $5,122, about $427 a month. The estimator above runs the same math for any price and area.

Who sets and collects Williamson County property tax

The County Commission and each city's governing body set rates every year. The Assessor values property but doesn't set rates or send bills; the Williamson County Trustee bills and collects for the county, FSSD, Franklin, Brentwood, Nolensville and Thompson's Station. Spring Hill collects its own city tax at City Hall. The county's rate page also lists Fairview as collecting its own, while the 2026 rate sheet shows the Trustee collecting it, so Fairview owners should read their first bill closely.

What each part of the property tax rate pays for

The county's $1.30 is five separate levies. Not every area pays all five, which is why the county portion of the rate shows as $1.30, $1.27, $1.21 or $1.18 depending on where you live. Each line below shows what it adds on the $913,277 typical home.

Williamson County general fund tax

The county general fund levy is 26 cents per $100 assessed. It adds about $594 a year.

Williamson County school tax

The general purpose school levy, 77 cents, funds Williamson County Schools and is the biggest single piece of the county rate. It adds about $1,758 a year.

Williamson County debt service and rural debt tax

General debt service is 15 cents, about $342. Rural debt service, 9 cents or about $205, isn't charged inside FSSD, where FSSD's own levies take its place; that's why the county portion is lower there.

Solid waste tax in Williamson County

The 3-cent solid waste and sanitation levy adds about $68. The rate sheet's arithmetic shows it isn't charged inside Franklin or Spring Hill, which brings their county portion to $1.27.

Franklin city property tax

Franklin's city rate is 29.6 cents in 2026, unchanged from 2025 and down from 32.61 cents before the reappraisal. It adds about $676. A listing or website still quoting 32.61 cents is using the 2024 figure.

FSSD property tax

The FSSD levy is 76.73 cents: 61.23 for the general fund and 15.5 for bond interest. It adds about $1,752 to the typical bill, offset by a few cents in county levies that FSSD homes don't pay.

When Williamson County property taxes are due

The Trustee mails statements in early October. Taxes are due from the first Monday in October and can be paid without interest through February 28 of the next year. For 2026 taxes, interest starts March 1, 2027 at 1.5% a month, and the Trustee can't waive it.

The bill goes to whoever owned the home on January 1, and the tax year is the calendar year. If you buy mid-year, the seller's share is settled at closing; our Tennessee closing costs guide covers that proration. If your lender escrows, the bill you receive is for your records. You can pay online, by mail to the Trustee at 1320 West Main Street, Suite 203, Franklin, at the check-only drop box, or in person.

Does Tennessee have a homestead exemption on property tax?

No, not one that cuts the taxable value for every owner-occupant the way Texas and Florida do. If you're moving from either state, budget on the full assessed value. Tennessee's help is targeted by age, disability or income, and Williamson County adds two programs of its own. Combined Williamson rates work out to 0.325% to 0.561% of value a year: $2,968 to $5,122 on the $913,277 typical Franklin home.

Tennessee property tax relief program

The state program covers owners 65 or older, or disabled, by December 31, 2026, who live in the home and whose combined 2025 income is no more than $38,470. Relief is figured on up to $33,600 of the home's value, so it covers part of the bill, not all of it. Disabled veterans and their surviving spouses qualify with no income limit, on up to $175,000 of value. The county takes 2026 applications until April 5, 2027, and the taxes must be paid first.

Williamson County property tax freeze

The freeze holds your property tax at the amount for the year you qualify. You must be 65 by December 31, 2026, live in the home, and have combined 2025 income of $69,150 or less from all sources, not just taxable income. You re-apply every year, it covers the house and up to five acres, and the frozen amount resets if you add improvements or move. The first year you qualify matters most, because that's the bill you lock.

Williamson County broad base tax relief

Owners 65 or older with combined 2025 income up to $63,000 can get a refund check after paying in full. It covers county property tax and part of the wheel tax and sales tax. Book an appointment with the Trustee's office at (615) 790-5709 for any of the three programs.

Property tax reappraisal and appeals in Williamson County

The county reappraises every four years; the last countywide reappraisal was 2025. The county-only rate fell from $1.88 in 2024 to $1.30 in the reappraisal year and stayed there in 2026. So a 2024 tax figure on an old listing sheet can't budget a 2026 purchase.

How to appeal a Williamson County property assessment

Preliminary assessments are open for inspection in May, and owners whose value changed are notified by mail. You can ask the Assessor for an informal review, but book a County Board of Equalization appointment at the same time to keep your appeal rights. The board meets in June; call the Assessor's office (615-790-5708) in the first week of June. If you disagree with its decision, the next step is the State Board of Equalization.

Where buyers lose money on Williamson County property tax

The dollar costs below use the typical $913,277 Franklin home.

• Budgeting from a pre-2025 bill. Apply the 2024 Franklin rate of $2.1561 to today's value and you'd budget about $4,923 instead of $3,575.
• Assuming the FSSD side from a mailing address. Getting it wrong costs $1,546 a year. Pull the parcel record on the Assessor's property search.
• Paying after February 28. Interest is 1.5% a month: about $54 a month on a $3,575 bill.
• Reading a new-build bill as the real one. The Assessor prorates new construction until September 1, so the first bill can cover only part of a year; the next one shows the full house.
• Missing your first freeze year. If you qualify at 65 and wait, the bill you lock is a later one, with any rate or value increases already in it.

Property tax vs Tennessee's other taxes on a Franklin move

Tennessee doesn't tax wages, and the Hall tax on interest and dividends ended after 2020; the Tennessee income and Hall tax guide has the details. Sales tax in Williamson County is 9.75% on most purchases, and the Tennessee sales tax page covers the single-article cap on cars and appliances.

These figures come from the Trustee's published 2026 rates; for your own bill or a relief application, confirm with the Williamson County Trustee or a Tennessee CPA.
