Kentucky Tax Overview for Estimated Payments

Kentucky has a flat state income tax rate of 3.5%, but many of Kentucky's cities and counties also charge local occupational taxes — making Kentucky one of the more complex states for paycheck calculations. Louisville (Jefferson County) charges a 2.2% occupational tax, Lexington-Fayette charges 2.25%, and dozens of smaller cities have their own rates ranging from 1% to 2.5%. The combination of state and local taxes means Louisville workers pay about 5.7% total, and Lexington workers pay about 5.75%. Kentucky's standard deduction is $3,360 — lower than most states. Compared to neighboring Tennessee (no income tax) and Indiana (2.95% state), Kentucky's combined burden is notably higher for workers in major cities.
