The IRS has begun mailing notices to businesses and other payers that filed certain returns with information that doesn’t match the agency’s records. These CP2100 and CP2100A notices are sent by the IRS twice a year to payers who filed information returns that are missing a Taxpayer Identification Number, have an incorrect name or have a combination of both. Payers are required to file with the IRS various information returns reporting payments they make to independent contractors, customers and others. These include Form 1099-MISC (Miscellaneous Income) and Form 1099-NEC (Nonemployee Compensation). Contact us if you have questions about filing information returns.
