The W-9 is an IRS form requesting official information about a vendor. Douglas County, KS uses this information to report vendor payments to the IRS (via 1099M), when required. The W-9 should be completed and returned to Douglas County, not the IRS.
Usually checks are cut and mailed every Thursday after the County Commissioners have met on Wednesday afternoon and approve the Accounts Payable report. Occasionally, holidays or other circumstances change the schedule.
