This bulletin announces changes to the state of Louisiana income tax withholding effective beginning with wages paid for Pay Period 03 and Pay Period 04.  Listed below are descriptions of the specific changes to be implemented.

Louisiana State Income Tax Changes for Pay Period 03

Prior to the processing of Pay Period 03, if an employee claimed no personal exemptions (0 in position 1 of State-Tax-No-Exemptions), Louisiana did not allow the employee to claim dependent exemptions (positions 2 and 3 of State-Tax-No-Exemptions).  The Payroll/Personnel System processed 00 dependents regardless of what the employee had in positions 2 and 3 of State-Tax-No-Exemptions on the Information/Research Inquiry System (IRIS) Program IR105, State Tax.

After completion of Pay Period 02 processing and prior to the processing of the Personnel Edit System (PINE) for Pay Period 03, the National Finance Center (NFC) generated Document Type 140, State Income Tax Certificate, to modify the employee State-Tax-No-Exemptions code to 000 on IRIS Program 105 for employees who claimed no personal exemptions with dependent exemptions.  Note:  If a Form L-4, Employee’s Withholding Allowance Certificate, was processed for an employee in Pay Period 01 through Pay Period 03, 2003, NFC will not change the employee’s exemption number to 000.  The exemption number will remain the same as is currently on IRIS Program IR105 and Louisiana state income tax will be withheld based on that exemption data.

Employees who are currently designated on the Payroll/Personnel System database as exempt from Louisiana state income tax will continue to be exempt from state withholdings.

Louisiana State Income Tax Changes for Pay Period 04

In addition, beginning with wages paid for Pay Period 04, the following changes to state of Louisiana income tax withholdings will be made:

Personnel offices should notify their employees to review their projected tax liability and make adjustments to their withholdings as appropriate.  Employees may adjust their state tax withholdings by submitting a new Form L-4, through either the Employee Personal Page on the NFC home page (, through Employee Express, or to their personnel office.
