USA State Payroll Rates + Resources: State of Louisiana: Filing State Income Taxes, W-2s, and 1099s

Purpose 

This documentation outlines the processes and requirements associated with Filing State Income Taxes, W-2, and 1099s, as needed, in the state of Louisiana.

State Income Tax Withholding

To determine the amount of state income tax withholding, employees should complete a Louisiana Department of Revenue Employee Withholding Exemption Certificate (L-4). Every employee, on or before the date of commencement of employment, shall furnish his or her employer with a signed Louisiana Withholding Exemption Certificate (L-4) relating to the withholding status, exemptions dependents, and/or increase or decrease in the amount to be withheld each pay period.  

Employers are required to keep copies of completed state L-4 forms for their employees in their files. The forms serve as verification that state income taxes are being withheld according to the employee’s instructions and needs to be available for inspection if the state requests it. 

The Forms W-4 and L-4 generally are valid until the employee provides new ones. However, employees who claim exemption from withholding must renew the exemption annually by filing new Forms W-4 or L-4 by February 15th of each year.
