Form W-9 Compliance Procedures and Best Practices

Nov 06 2025

2:10 PM - 3:30 PM PDT

Milano VII-VIII

This session covers the best practices associated with Form W-9. This form is a key compliance mechanism for accounts payable departments, but sometimes there’s mystery about how to use it properly. This session will help unravel that mystery. The W-9 helps with due diligence relating to Form 1099, but it’s also key for certain types of payments that fall under the heading of “FATCA” payments – something many businesses are not even aware of. We will also look at various scenarios and how the W-9 would be expected to look in those situations. In addition, the IRS released a new version of the W-9 in March of 2024, and we will look at what

those changes are and how it affects you. This session is expanded and enhanced from prior W-9 sessions given at IOFM conferences.

Learning Objectives:

  • What exactly is the W-9?

  • Procedures and best practices

  • FATCA payments

  • Scenarios and sample forms
