What return form should accompany my payments?


  • Quarterly filers should attach payments to Form L-1 Employer’s Return of Louisiana Withholding Tax.
  • Monthly filers should attach payments to Form L-1V Withholding Payment Voucher. However, income taxes withheld in the last month of a quarter (March, June, September, December) should be submitted with the L-1 return for the respective quarter.
  • Semimonthly filers must submit payments electronically. One option is to use LDR’s online service Louisiana Taxpayer Access Point (LaTAP) .
