Property Tax Rates: Williamson County vs. Davidson County

Property taxes are an important part of the cost of owning a home in Middle Tennessee, but comparing Williamson County and Davidson County is not as simple as looking at two tax rates. The amount a homeowner actually pays depends on the property's appraised value, Tennessee's assessment ratio, the local tax rate, and—in some areas—additional city or service district taxes.

For buyers considering homes in Nashville, Franklin, Brentwood, Nolensville, or other communities across Middle Tennessee, understanding these differences can make it easier to compare the true cost of homeownership.

Here's what you should know about Williamson County vs. Davidson County property taxes in 2026.

• Tennessee residential property is assessed at 25% of its appraised value before the local tax rate is applied.
• Williamson County's 2026 property tax rate varies depending on the municipality and applicable districts.
• Davidson County's 2026 rate is $2.782 per $100 of assessed value in the General Services District and $2.814 in the Urban Services District.
• The tax rate is only one part of the equation. Buyers should also consider the property's assessed value, purchase price, and other ownership costs.

How Tennessee Property Taxes Are Calculated

Before comparing Williamson County and Davidson County, it helps to understand how Tennessee calculates property taxes.

For a typical residential property, the process is:

Appraised Value × 25% = Assessed Value

Then:

Assessed Value ÷ 100 × Local Tax Rate = Estimated Property Tax

Tennessee establishes a 25% assessment ratio for residential property. The applicable local government then applies its tax rate to the property's assessed value.

For example, if a home has an appraised value of $500,000:

• Appraised value: $500,000
• Residential assessment ratio: 25%
• Assessed value: $125,000

The applicable county, city, and district tax rate is then applied to that $125,000 assessed value.

This is why comparing property tax rates by themselves can be misleading. A lower rate does not necessarily mean a lower tax bill if the property's assessed value is significantly different.

What Are the 2026 Property Tax Rates in Williamson County?

Williamson County does not have one single tax rate that applies to every property.

The 2026 rate depends on where the property is located and whether it falls within a city or special school district. Published 2026 rates include:

• Williamson County only: $1.30 per $100 of assessed value
• Brentwood: $1.49 total
• Franklin, outside FSSD: $1.566 total
• Nolensville: $1.64 total
• Thompson's Station: $1.403 total
• Franklin/FSSD: $2.2433 total
• Fairview: $2.1404 total
• Spring Hill: $2.009 total

These rates are calculated per $100 of assessed property value.

For buyers searching for homes for sale in Williamson County, this distinction matters. Two homes located in different municipalities can have different property tax rates even though both are within Williamson County.

That's why it's important to evaluate the specific property rather than assuming every Williamson County home has the same tax rate.

What Are the 2026 Property Tax Rates in Davidson County?

Davidson County operates differently because it is part of the Metropolitan Government of Nashville and Davidson County.

For 2026, the General Services District (GSD) rate is $2.782 per $100 of assessed value. Properties located in the Urban Services District (USD) have a combined rate of $2.814 per $100 of assessed value.

Davidson County also includes several incorporated satellite cities. Properties located in those communities may have additional city taxes depending on the property's jurisdiction.

For someone considering Nashville real estate, this means the property's exact location matters when calculating the tax obligation.

As with Williamson County, buyers should verify the applicable rate and current assessment for the individual property before making a purchasing decision.

Williamson County vs. Davidson County: A Simple Example

Let's use a hypothetical home with a $500,000 appraised value to illustrate how the rates can affect the tax calculation.

Because residential property is assessed at 25%, the assessed value would be:

$500,000 × 25% = $125,000

Using the published 2026 rates, the approximate annual tax would be:

These are illustrative calculations, not estimates of a specific property's actual tax bill.

Actual property taxes can vary based on the property's assessed value, jurisdiction, applicable districts, exemptions, and changes to local tax rates.

The example does demonstrate an important point: property taxes can have a meaningful impact on the cost of homeownership, particularly when comparing properties across county lines.

Why a Lower Tax Rate Doesn't Automatically Mean a Lower Overall Cost

It's easy to look at two tax rates and assume that the property with the lower rate is automatically the better financial choice.

Real estate is more complicated than that.

When comparing homes, buyers should consider the complete cost of ownership, including:

• Purchase price
• Property taxes
• Homeowners insurance
• HOA fees
• Maintenance and repairs
• Utilities
• Mortgage and financing costs
• Commute and transportation expenses
• Potential changes in property assessments
• Potential changes in local tax rates

A home with a lower tax rate could have a higher purchase price or other costs that affect the overall monthly budget.

On the other hand, a property with a higher tax rate may offer location, features, or other benefits that are more important to a particular buyer.

The best decision depends on the entire financial and lifestyle picture.

Reappraisal Can Affect Your Property Tax Bill

Another important factor is the difference between appraised value and tax rate.

Counties periodically conduct property reappraisals to bring assessed property values more in line with current market conditions.

Davidson County completed a reappraisal for 2025, with the next scheduled reappraisal occurring in 2028.

A change in a property's appraised value can affect its assessed value and, consequently, the amount of property tax owed.

It's important to understand that a change in assessed value and a change in the tax rate are separate parts of the property-tax equation.

For buyers, this is another reason to look beyond the tax amount shown on a listing. Understanding the property's current assessment and applicable tax jurisdiction can provide a more complete picture of its potential ownership costs.

What Buyers Should Check Before Purchasing

If you're comparing homes in Nashville, Williamson County, or surrounding Middle Tennessee communities, don't rely solely on the property tax information displayed in a listing.

Before making an offer, consider verifying:

• The property's current assessed value
• The applicable county tax rate
• Any city tax
• Applicable school or service district taxes
• The property's recent tax history
• Whether the property falls within a special service district
• Whether exemptions affect the current tax bill
• Whether the current tax situation could change after the purchase

It can also be helpful to compare the estimated property tax with the property's purchase price and your expected mortgage payment.

This gives you a better idea of the property's total monthly housing cost, rather than focusing on just one expense.

How the Ben Kinney Team Can Help You Compare the Numbers

Choosing between Williamson County and Davidson County is about more than finding a home you like. Property taxes, assessed value, location, and the overall cost of ownership can all affect whether a property makes sense for your goals.

The Ben Kinney Team brings local market knowledge together with technology and a broader network of real estate resources to help buyers make informed decisions.

One resource the team can leverage is AreaPro, which provides property and value assessment tools that can be useful when evaluating a home's market position.

When comparing homes across Williamson and Davidson counties, that combination can be valuable. Instead of looking at the tax rate in isolation, buyers can evaluate the property's value, location, potential costs, and overall fit with their financial goals.

The goal isn't simply to find the home with the lowest property tax bill. It's to understand the full picture so you can make a confident decision about where and what to buy.

The Right Comparison Depends on Your Goals

There isn't one county or tax structure that is automatically right for every buyer.

Someone prioritizing a particular commute may value one location over another. Another buyer may place more importance on the type of property, neighborhood environment, schools, access to shopping and restaurants, or proximity to work.

Property taxes should be part of that conversation—but they shouldn't necessarily be the only deciding factor.

If you're comparing living in Nashville with communities such as Franklin, Brentwood, Nolensville, or other areas in Williamson County, look at the complete cost and lifestyle of each option.

A good real estate decision balances the numbers with what you actually want from your home and community.

Final Thoughts

Understanding property tax rates in Williamson County vs. Davidson County can help Middle Tennessee buyers make more informed decisions.

Tennessee's residential assessment ratio also plays an important role in determining the final tax calculation.

The most important takeaway is that you shouldn't compare counties based solely on the headline tax rate. The property's assessed value, exact location, applicable districts, purchase price, and other ownership expenses all matter.

If you're considering buying real estate in Nashville or Williamson County, take the time to look at the complete financial picture for each property.
