The deadline for filing state taxes in Kentucky typically aligns with the federal tax deadline, which is usually April 15 each year. If April 15 falls on a weekend or a holiday, the deadline may be extended to the next business day. For most taxpayers, this means that state income tax returns must be submitted by this date to avoid potential penalties and interest on unpaid taxes. However, it is important to note that taxpayers may request an extension for filing; this extension allows additional time to file the return, but any taxes owed still need to be paid by the original deadline to prevent late fees.
