Williamson County Property Taxes Explained for Homebuyers (2026)
Williamson County property taxes are an important part of your homebuying budget — and the good news is they’re surprisingly reasonable, especially since Tennessee has no state income tax. Here’s a clear breakdown of how they work, the current rates, and what to expect when you buy in Franklin, Brentwood, and the surrounding communities.
How Property Taxes Work in Tennessee
Tennessee assesses residential property at just 25% of its appraised value. Your annual bill is that assessed value, divided by 100, multiplied by the combined tax rate (the county rate plus any city rate). Because of that 25% assessment ratio, your taxable value is far lower than your home’s market price.
The Williamson County Tax Rate
After the recent countywide reappraisal, Williamson County lowered its property tax rate to $1.30 per $100 of assessed value, down from $1.88. On a $700,000 home, that means an assessed value of $175,000 and roughly $2,275 in county property tax — modest compared to much of the country.
City Rates Add a Little More
Homes inside city limits also pay a city rate on top of the county rate. Brentwood’s city rate is very low at about $0.19 per $100, while Franklin and Spring Hill add their own modest rates. Homes in unincorporated Williamson County pay only the county rate, with no city tax at all.
No State Income Tax
One of Tennessee’s biggest financial advantages is that it has no state income tax on wages. Combined with the county’s low property tax rate, that makes Williamson County genuinely tax-friendly — a major reason so many buyers relocate here from higher-tax states.
Tips for Homebuyers
Always verify the exact combined rate for a specific address, since it depends on the city. Ask about recent reappraisals, and look into exemptions — such as those for seniors or disabled veterans — through the Williamson County Trustee’s office. Your property taxes are typically collected monthly through your mortgage escrow.
Budgeting for Your Williamson County Home
Property taxes are a manageable but real part of homeownership here, so factor them into your monthly payment as you shop. If you’d like help estimating taxes on a specific home or neighborhood, reach out to Exclusive Tennessee Homes and we’ll walk you through the numbers.

How are property taxes calculated in Tennessee?
Residential property is assessed at 25% of its appraised value. You then multiply that assessed value (divided by 100) by the combined county and city tax rate. For example, a $700,000 home is assessed at $175,000, so the county portion is about $2,275.
Does Tennessee have a state income tax?
No. Tennessee has no state income tax on wages, which — combined with relatively low property taxes — makes Williamson County one of the more tax-friendly places in the country to own a home.
Are property taxes higher in Franklin or Brentwood?
Both pay the same Williamson County rate, but each city adds its own modest rate. Brentwood’s city rate is very low, around $0.19 per $100. Always confirm the exact combined rate for a specific address, since it varies by city and whether the home is in an incorporated area.
