Vendor W9/1099 Maintenance
You should start reviewing your vendors’ 1099 setup at least several days before you plan to pull and process 1099’s. For 2025 reporting, Horizon recommends you begin this review as soon as you receive the End of Year updates. This year’s update includes important changes to the review process.
The Vendor Maintenance Grid will show information from the Vendor Master that is used to create 1099 data. Review and update the vendor data before pulling 1099 data for this year. Any updates to vendor information will also update the Vendor Master.
The Vendor Maintenance Grid is also available in the Section 8 module for Landlord W9/1099 Maintenance. The Section 8 department should be reminded to review the updated instructions to review the landlords’ information several days before the pull and process is to occur.
Any updates to vendor information in the Vendor W9/1099 Maintenance grid will also update the Vendor Master.
