Kentucky Tax Overview for Estimated Payments
Kentucky has a flat state income tax rate of 3.5%, but it's one of the most city-tax-heavy states in the country. Most of Kentucky's major cities and counties charge their own occupational license fees (functionally local income taxes) on top of the state rate. Louisville (Jefferson County) charges 2.2%, Lexington-Fayette charges 2.25%, Covington charges 2.25%, Bowling Green charges 1.95%, and Owensboro charges 1.95%. Dozens of smaller cities charge their own rates. The result: Louisville workers pay a combined 5.7%, Lexington workers pay 5.75%. Kentucky's standard deduction is $3,360 for single filers — low by national standards.
Here's what a single Louisville worker keeps in 2026. On a $50,000 salary, take-home is approximately $39,901 per year ($3,325/month) after federal, FICA, state, and Louisville city taxes. At $80,000, take-home is approximately $60,136 ($5,011/month). At $100,000, you keep about $73,084 ($6,090/month). At $150,000, take-home is approximately $104,618 ($8,718/month). Workers in smaller Kentucky cities with no local tax pay roughly $1,760 more per year at $80,000 than Louisville residents.
Compared to neighboring Tennessee (no income tax), a Louisville worker at $80,000 takes home approximately $4,442 less per year. Against Indiana (2.95% flat + county), Kentucky's burden is similar for Indianapolis workers but higher than Indiana suburban workers. Against Virginia (effective 5.75% for most earners), Louisville workers at $80,000 pay slightly less in total. Against Ohio, the comparison depends on which Ohio city you're comparing — Columbus (2.5% city tax + 2.75% state) is similar to Louisville total.
Watch out: Kentucky's occupational tax applies to wages earned in that city, not just to residents. If you work in Louisville but live in a suburb with no local tax, you pay the Louisville 2.2% occupational tax on income earned there. If you work from home, you generally pay your city's rate, not your employer's city's rate. Louisville and Lexington in particular enforce collection from remote workers based in those cities, so if you switched to remote work, verify that your payroll reflects your home location rather than your employer's office location.
