Kentucky Form 740-EXT is an application used to request an extension of time to file an income tax return in Kentucky. This form is typically used by individuals, general partnerships, and fiduciaries who need more time beyond the standard filing deadline. If you have already requested a federal extension (via Form 4868), you may not need to file this Kentucky extension unless you owe money with your state taxes. Filing electronically is an option, and you can also make payments through a direct debit transaction. It is important to remember that you must complete Section I and the Payment Voucher to successfully file the extension request. If no payment is being submitted, leave the “Amount Paid” box blank. For those filing electronically, Section II requires your banking information if you choose to pay via direct debit. This form needs to be attached to your return when it is finally filed to avoid penalties. Make sure to keep a copy for your records.
