If you're comparing property taxes in Prospect, KY, you've likely noticed two homes in the same ZIP with very different tax bills. That's not a typo. Prospect sits in two counties, and a few more lines get added inside city limits, so it's hard to budget from a listing alone. I'm Spencer Lowe, a Kentucky real estate agent licensed since 2019 with Real Estate Go To, serving Prospect, KY and the Louisville area. This guide lays out the published rates with their sources and dates, shows how they stack up, and explains how to check a specific address.

How Do Property Taxes Work in Prospect, KY?
Kentucky property taxes are charged per $100 of assessed value, and your total rate is a stack of separate rates: state, county, school district, any special districts, and the city if you're inside city limits. Prospect is in both Jefferson and Oldham counties (Kentucky Secretary of State), so the first question for any house is which county it's in, even when two homes share a 40059 address (Prospect, KY ZIP Codes Explained). Check the Jefferson County PVA or Oldham County PVA record.
Most rates below are 2025 rates, the latest full set published. 2026 rates are being set now, so check current figures before you budget.

What Would Taxes Be on a $500,000 Home?
Here's how the published 2025 Jefferson County rates stack up on a home assessed at $500,000, outside the Urban Service District:
- State + Metro + JCPS: 0.106 + 0.118 + 0.717 = 0.941 per $100, or $4,705
- Add the City of Prospect (0.183) if inside city limits: +$915
- Add a fire district if the address is in one, for example Anchorage/Middletown at 0.175: +$875
That's $4,705 to $6,495 a year depending on city limits and fire district, before any exemptions. Your real bill may include other line items and depends on your assessed value, so treat this as an illustration and check the actual bill for any house you're considering.
