Accounts Payable Information for Vendors
The LaGov Interim Support Group (ISG) is the acting accounts payable central control agency for vendor master data and 1099 reporting in the LaGov ERP system for the period of time for which both LaGov and the Integrated Statewide Information Systems (ISIS) are operating concurrently. The ISG has taken over these functions from the Office of State Uniform Payroll (OSUP), and once LaGov is implemented statewide, the ISG will turn over these functions to the appropriate control agency.
The ISG is responsible for the following:
- Unblocking vendors who have registered through Supplier Self Registration - Newly registered vendors are required to submit a completed IRS Form W-9 to the ISG. No payments can be issued until the W-9 information is verified and the vendor is unblocked.
- Enrolling vendors in direct deposit - Vendors are encouraged to enroll in direct deposit, as electing to receive payments through direct deposit can result in receiving payments faster. Vendors interested in enrolling in direct deposit must submit a Direct Deposit Form to the ISG. All direct deposit payments will be identified as "LAGOV VENDOR PYMT".
- Printing and mailing IRS Forms 1099-MISC and 1099-S - The ISG will provide these forms to vendors who meet the federal criteria, and will also submit this information to the IRS.
If you have questions regarding the requirements for having a vendor record unblocked, enrolling in direct deposit, or questions pertaining to IRS Form 1099, contact the ISG via email at DOA-LAGOV-ISG@LA.GOV or call (225) 219-6888. Completed W-9 or Direct Deposit forms may be emailed, or they can be faxed to (225) 219-6754.
