Most businesses that issue 1099s find it daunting to respond to CP-2100 letters. The IRS uses these letters to communicate with you whether you’ve missed a TIN in your information return, entered an incorrect one, or a combination of both. Join our speaker, Jason Dinesen to learn how you can respond to CP-2100 letters in 2022, and how to possibly avoid them in the first place.

What do the CP-2100 letters include? Do the notices inform the payers that they’re responsible for backup withholding? What’s the best way to avoid them, and if you’ve received one, how can you respond to it?

How to correct your backup withholding errors? When do the penalties apply? What’s there to know about the IRS records and the combination of your name and Taxpayer Identification Number (TIN)? What are B-Notices? When to send your first and second B-Notices? Are they your defence against penalties?

As time allows, we will also delve into employee vs. contractor — is that “contractor” really an employee?

Why You Should Attend:

CP-2100 letters come to your business from the IRS. These letters notify you that the social security number you put on a 1099 doesn’t match what’s in the IRS’s system. For example, the social security number of a contractor. When your business receives such a letter, you must take action by sending a “B Notice” to the other party.

This webinar will discuss how you can take steps to avoid CP-2100 letters, to begin with, through the IRS’s “TIN Matching” program and proper usage of the Form W-9. We’ll cover more about B Notices in this program, and cover backup withholding.
