Every employer that has resident or nonresident employees performing services (except employees exempt from income tax withholding) within Louisiana is required to withhold Louisiana income tax based on the employee's withholding exemption certificate.
Wages of Louisiana residents performing services in other states are subject to withholding of Louisiana income tax if the wages are not subject to withholding of net income tax by the state in which the services are performed. If residents earn wages in another state, they are subject to withholding only in that state, except that Louisiana residents who earn wages in Texas are subject to Louisiana withholding, because Texas does not have a state income tax.
Taxes must be withheld on “wages,” which includes all cash and noncash payments for services performed by an employee.
Exclusions. Payments for the following services are exempt from withholding:
• Services by news carriers under the age of 18
• Services not in the usual course of the employer's business, unless the compensation exceeds $50
• Under some circumstances, services by newspaper or magazine vendors
• Services by ordained ministers or members of a religious order
Additionally, the following are exempt from withholding: contributions to a “cafeteria” benefit plan or to a deferred compensation plan, such as a 401(k) plan; business expense advances or reimbursements; and payments made under a wage continuation plan for periods when employees were absent from work because of sickness or injury, to the extent the benefits weren't paid for by employer contributions.
