Short-Term Rental Taxes in Kentucky: What Investors Need to Know in 2025
4% flat income tax (with planned further reductions) | Conforms to federal bonus depreciation | 1% state transient room tax + local taxes (1–7.5%) | Top markets: Red River Gorge, Lake Cumberland, Louisville | Derby season creates extreme short-term demand spikes in Louisville
Kentucky offers a straightforward and investor-friendly state tax environment for STR operators: a flat 4% income tax that has been on a downward trajectory, full conformity to federal bonus depreciation, and relatively low transient room taxes in most markets. The primary STR markets are split between outdoor recreation (Red River Gorge, Lake Cumberland, Daniel Boone National Forest) and urban event demand (Louisville, particularly around the Kentucky Derby).
Kentucky State Income Tax
Kentucky simplified its tax structure by adopting a 4% flat income tax effective 2023, down from a graduated structure with a prior top rate of 5%. Kentucky has further reductions written into law contingent on revenue triggers. The flat rate structure means all net rental income is taxed at the same rate, simplifying planning. Kentucky conforms to federal depreciation definitions — cost segregation deductions reduce both federal and Kentucky taxable income in year one.
Kentucky Transient Room Taxes by Market
| Market / County | State Tax (1%) | County/City Tax | Estimated Total |
|---|---|---|---|
| Louisville (Jefferson County) | 1% | 4.5–7.5% | ~5.5–8.5% |
| Lexington (Fayette County) | 1% | 4% | ~5% |
| Stanton/Powell County (Red River Gorge gateway) | 1% | 2% | ~3% |
| Lake Cumberland (Russell/Wayne County) | 1% | 1–2% | ~2–3% |
| Mammoth Cave area (Edmonson County) | 1% | 1–2% | ~2–3% |
| Bowling Green (Warren County) | 1% | 3% | ~4% |
Red River Gorge: Kentucky's Top Outdoor STR Market
The Red River Gorge Geological Area in Powell, Wolfe, and Menifee counties is one of the most spectacular rock climbing and hiking destinations east of the Mississippi. The Daniel Boone National Forest setting — with over 100 miles of hiking trails, the Natural Bridge State Resort Park, and world-renowned climbing routes — draws outdoor enthusiasts year-round. STR demand is driven by climbers, hikers, backpackers, and couples seeking secluded mountain retreats.
Red River Gorge STR properties tend to be rustic cabins and cottages accessible to trailheads. Property values are modest compared to national markets — $150,000–$350,000 for typical cabins — with solid gross revenue potential of $30,000–$80,000 annually for well-positioned properties. The outdoor amenity components (decks, hot tubs, fire pits) support meaningful cost segregation benefits relative to purchase price.
Lake Cumberland: Kentucky's Lakefront Market
Lake Cumberland in south-central Kentucky is known as the 'Houseboat Capital of the World' — and houseboat rentals are a unique STR category here alongside traditional lakefront cabin STRs. The lake draws water sports enthusiasts, boaters, and fishing tourists. Peak season is Memorial Day through Labor Day, with strong shoulder demand in spring and fall for fishing.
Louisville: Derby Season Demand
Louisville's STR market is highly event-driven, with the Kentucky Derby (first Saturday in May) creating extreme demand spikes. Churchill Downs and the surrounding Highlands and NuLu neighborhoods are prime STR locations. Derby weekend properties routinely command 10–15x normal nightly rates, with many bookings confirmed a year in advance. Louisville also has consistent demand from bourbon trail tourism, conventions, and University of Louisville events.
Cost Segregation in Kentucky
Kentucky's full bonus depreciation conformity and 4% flat tax create clean math for cost segregation ROI. Red River Gorge and Lake Cumberland properties with high outdoor amenity ratios typically yield 20–28% personal property ratios. A $300,000 gorge cabin with $75,000 in cost seg deductions saves approximately $27,750 federal (at 37%) + $3,000 Kentucky (at 4%) = $30,750 in year one, against a study cost of $3,500–$6,000.
