The IRS TIN matching process plays a critical role in ensuring accurate tax reporting and preventing costly IRS penalties. Businesses that file information returns such as Forms 1099 must verify taxpayer details before submission, and the IRS TIN matching program is designed to help organizations do exactly that.
In this in-depth guide, we’ll explain what IRS TIN matching is, how the online taxpayer identification number TIN matching program works, its benefits, challenges, compliance rules, industries that rely on it, and best practices for error-free reporting.
What Is IRS TIN Matching?
IRS TIN matching is a verification service provided by the Internal Revenue Service that allows payers to confirm whether the Taxpayer Identification Number (TIN) and name combination they have on file matches IRS records.
The TIN may be:
- Social Security Number (SSN)
- Employer Identification Number (EIN)
- Individual Taxpayer Identification Number (ITIN)
The IRS TIN match system helps reduce filing errors before submitting information returns like Forms 1099, 1098, and W-2G.
