What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Oldham County, KY

In Oldham County, Kentucky, homes carry a median value of $393,100, and the annual property tax bill on such a home averages $3,519. That reflects an effective rate of 0.895%, which sits above Kentucky's statewide median of 0.675% and also edges past the national figure of 0.794%. Among the state's 120 counties, Oldham ranks 7th for property tax rate. Buyers weighing a move to Buckner, Goshen, or Pewee Valley should consider how those taxes fit alongside local earnings: median household income reaches $122,497, with per-capita income at $54,496. Those income levels help offset the higher tax rate, since a $3,519 annual bill amounts to a smaller share of a six-figure household budget. The trade-off is clear — pricier homes and above-average rates, but strong earning power across the county.

Frequently asked questions

What is the property tax rate in Oldham County, KY?
The effective rate is 0.90% — meaning the median tax bill equals about 0.90% of the median home value.
How much are property taxes on a median home?
On the median home ($393,100), the estimated annual bill is about $3,519.
Is Oldham County's rate high or low?

How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Oldham County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Oldham County assessor within the local deadline, typically with comparable sales as evidence.
