The Kansas K-19 form plays a crucial role in the state's tax system, particularly for partnerships, S corporations, limited liability companies (LLCs), and limited liability partnerships (LLPs) that have nonresident owners. This form is designed to report the Kansas income tax that must be withheld from the taxable income of these nonresident owners, whether that income is distributed or not. It includes several sections that gather essential information, such as the entity's details, the nonresident owner's information, and the specifics of the taxable income and withholding amounts. Notably, the form also outlines the process for reporting ownership shares and tax withheld for nonresident owners who are themselves pass-through entities. The withholding tax rate for nonresident owners is currently set at 4.9%, and entities must comply with additional requirements, including the completion of accompanying forms like the KW-7S and KW-7. For those who wish to opt out of withholding, the form provides an avenue through an affidavit. Understanding the K-19 form is vital for ensuring compliance with Kansas tax regulations and avoiding potential penalties.
