CP-2100 Letters and B-Notices: Compliance Strategies and Risk Management | Product

When a contractor’s name and taxpayer identification number (TIN) don’t match IRS records, the IRS notifies the payer via a CP-2100 letter. What happens next is often misunderstood — and mishandled. In this timely 90-minute session, IOFM’s expert instructor Jason Dinesen will guide attendees through the full lifecycle of a CP-2100 letter, from receipt to resolution, including when to issue a B Notice, when to initiate backup withholding, and how to avoid costly mistakes with Forms 1099 and W-9.

Attendees will also get updates on the latest IRS Form W-9 revisions, common compliance pitfalls, and the correct procedures for dealing with contractors who don’t provide a valid TIN. Whether you're new to CP-2100s or looking to fine-tune your compliance protocols, this session delivers the clarity and practical guidance you need.
