The Brentwood, TN property tax rate is a combined $1.49 per $100 of assessed value: $0.19 goes to the City of Brentwood and $1.30 goes to Williamson County.1City of Brentwood. Brentwood City Commission Approves Budget for 2025-26 Fiscal Year2Tennessee Comptroller of the Treasury. County Assessment Summary Because Tennessee taxes residential property on only 25% of its appraised market value, the dollar amount you actually owe is far smaller than the rate alone suggests.
The Two Rates on Your Brentwood Bill
Property inside Brentwood city limits is taxed by two separate authorities. The city’s $0.19 rate has held steady for more than three decades. Williamson County’s $1.30 sits on top of it, producing the $1.49 combined figure. Both rates are set each year by their respective legislative bodies based on the budgets they adopt, so either number can move from one tax year to the next.3Williamson County, TN – Official Site.

If your address is in unincorporated Williamson County rather than inside Brentwood city limits, only the $1.30 county rate applies to you. The city portion is tied to the municipal boundary.
How to Calculate What You Owe
Tennessee law assesses residential property at 25% of its appraised value, so only a quarter of what the assessor says your home is worth is actually subject to tax.4Justia. Tennessee Code 67-5-101 – Property Subject to Tax Generally Commercial and industrial property is assessed at 40%.5Tennessee Comptroller of the Treasury. How to Calculate Your Tax Bill
For a home appraised at $1,000,000, the math looks like this:
- Assessed value: $1,000,000 × 25% = $250,000
- City tax: $250,000 ÷ 100 × $0.19 = $475
- County tax: $250,000 ÷ 100 × $1.30 = $3,250
- Total: $3,725 per year
The one-step shortcut is to apply the combined $1.49 rate to the assessed value: $250,000 ÷ 100 × $1.49 = $3,725. Williamson County publishes an online calculator if you want to plug in your own appraised value.6Williamson County, TN – Official Site.

When the Bill Is Due
Property taxes become due and payable on the first Monday in October and can be paid without penalty through February 28 of the following year.7Tennessee Comptroller of the Treasury. Assessment Schedule That’s a roughly five-month window.
Starting March 1, interest of 1.5% is added to the unpaid balance, and another 1.5% accrues on the first of each month after that.8Justia. Tennessee Code 67-5-2010 – Interest – Delinquent Taxes On a $3,725 bill, that’s about $56 added every month you’re late.
Why Your Appraised Value May Jump
The appraised value behind the calculation comes from the Williamson County Property Assessor. The county runs on a four-year reappraisal cycle, shorter than the six-year default allowed under state law.9Williamson County, TN – Official Site. Purpose of a Reappraisal Properties are reviewed over several years and then revalued together in the cycle’s final year.
If Brentwood home prices have climbed since the last reappraisal, the new appraised value can rise sharply even though the tax rate itself hasn’t changed. The rate stays flat; the base it applies to moves. That’s the most common reason a Brentwood tax bill goes up.
Appealing an Appraisal That Looks Too High
You can challenge the assessor’s value if you think it overstates your home. The Williamson County Board of Equalization meets every June, and you schedule a hearing by calling the Assessor’s office during the first week of June.10Williamson County, TN – Official Site. Tax Rolls and Appeals Only the owner or an authorized representative can file. Miss that window and you lose your appeal rights for the year.
If the county board rules against you, the next step is the Tennessee State Board of Equalization. That appeal is due by August 1 of the tax year or within 45 days of the county board’s decision, whichever comes later.11Tennessee Comptroller of the Treasury. Appealing to the State Board of Equalization An administrative judge hears both sides and issues a written decision within 90 days.
Bring comparable sales. Recent sale prices of similar nearby homes are the most persuasive evidence, because that’s the same data the assessor relies on. Photographs of condition problems the assessor wouldn’t have seen also help.
Programs That Can Lower Your Bill
Tennessee runs several relief programs, and none of them are automatic. You apply through the county trustee’s office.
Seniors and Disabled Homeowners
Homeowners 65 or older, and those rated permanently and totally disabled by the Social Security Administration or another qualifying agency, may qualify for a state-funded reimbursement covering part of the taxes on the first $33,600 of appraised value. Applications typically open in October and are due the following April. Income limits apply and are reset annually by the Comptroller.
Disabled Veterans
Veterans with a total and permanent service-connected disability can receive a reimbursement covering taxes on the first $175,000 of their home’s full market value.12Justia. Tennessee Code 67-5-704 – Disabled Veterans Residence A surviving spouse who hasn’t remarried and still owns the home may also qualify. In Brentwood, where many homes exceed $175,000 in appraised value, the cap won’t cover the whole house, but the savings are still meaningful.
Property Tax Freeze
Homeowners 65 and older whose household income falls below a county-specific threshold can freeze their property tax amount so it doesn’t rise even if the assessed value does.13Tennessee Comptroller of the Treasury. Property Tax Freeze The Comptroller publishes updated income limits each year. The freeze stays in effect as long as you own and live in the home and your income remains under the limit. In a reappraisal-driven market like Brentwood’s, that lock can matter more than any one-time credit.
