Kansas Quarterly Wage Report and Unemployment Tax Return (K-CNS )

KS K-CNS Information

All employing units doing business in Kansas are subject to the provisions of the Employment Security law. However, not all are subject to the taxing provisions of the law. Coverage is determined by the type and nature of the business, the number of workers employed and the amount of wages paid for services in employment. The employer as Kansas law defines is responsible for filing employee payroll withholding taxes. Kansas law defines an employer as any person, firm, partnership, limited liability company, corporation, association, trust, fiduciary or any other organization: • who qualifies as an employer for federal income tax withholding purposes; • who maintains an office, transacts business, or derives any income from sources within the state of Kansas (whether or not the paying agency is in Kansas); • for whom an individual performs or performed any services of whatever nature as the employee of such employer; and, • who has control of the payment of wages for such services or is the officer, agent or employee of the person having control of the payment of wages.
