*Form 2210-K, Underpayment of Estimated Tax By Individual, Was Updated March 26, 2020*
Individual Income Tax is due on all income earned by Kentucky residents and all income earned by nonresidents from Kentucky sources.
Kentucky's individual income tax law is based on the Internal Revenue Code in effect as of December 31, 2018. The tax rate is five (5) percent and allows itemized deductions and certain income reducing deductions as defined in KRS 141.019. A full-year resident of Kentucky files Form 740 and a person who moves into or out of Kentucky during the year or is a full-year nonresident files Form 740-NP.
Individual income tax laws are found in Chapter 141 of the Kentucky Revised Statutes.
