Let me help you send the W-9 Forms to your existing contractors.
Collecting W-9s through QuickBooks Online or QuickBooks Contractor Payments lets you invite your contractors to complete their profile and submit a signed W-9 online anytime.
Here's how:
Go to Payroll, select Contractors or Contractors, and pick Contractors.
Select Add a contractor.
Enter the contractor’s name and email in the fields provided, then select Add contractor. We’ll send your contractor an email in real-time. The contractor’s profile will be saved in both the Contractors tab and the Vendors tab.
We’ll send your contractor an email inviting them to fill out and submit their W-9 info. They’ll either log in with an existing Intuit account if they have one, or create a free account to securely share their tax info with you. The whole process should only take a few minutes.
