Kentucky Form 461-K is a tax form used to calculate excess business losses for Kentucky residents. An excess business loss occurs when the total deductions from a taxpayer’s trade or business exceed the total income or gains from that business, plus a threshold amount. For the 2025 tax year, the threshold amount is $313,000 for individual taxpayers and $626,000 for married taxpayers filing jointly or separately on a combined return. Form 461-K helps taxpayers identify if their business losses exceed this threshold and if they need to adjust their losses accordingly. The excess business loss is then reported as a positive number on the tax return, where it will be carried forward as a net operating loss (NOL) to offset future income.
How to File Kentucky Form 461-K
Form 461-K should be filed by individuals, estates, and trusts who have business losses exceeding the allowed threshold. To complete this form, you will need to gather information from your Kentucky tax return (Form 740 or Form 740-NP) and federal return (Form 1040, Form 1040-SR, or Form 1041), including income from various business activities. The form must be filed along with your Form 740 or Form 740-NP. The steps outlined on Form 461-K help calculate whether your losses exceed the threshold and whether you need to carry those losses forward to future years as an NOL.
