IRS TIN matching tool

The IRS TIN Matching Tool is an online service used to verify that a payee’s name and Taxpayer Identification Number (TIN) combination matches IRS records.

What it’s for

Businesses and payers use it to reduce:

• backup withholding issues
• incorrect Form 1099 filings
• IRS notices due to name/TIN mismatches

Who can use it

Generally, it’s available to:

• payers who file information returns with the IRS
• authorized agents acting on behalf of payers
• some tax professionals or third-party filers with proper authorization

What it checks

It compares:

• legal name or business name
• TIN
  • SSN
  • EIN
  • ITIN
• sometimes name control rules, depending on the type of request

How it works

There are typically two ways:

1. Online TIN Matching
   • batch and interactive searches
   • available through IRS e-services after enrollment
2. Bulk TIN Matching
   • for larger lists of payees
   • file-based submission and response

Important notes

• A “match” means the name and TIN combination appears to match IRS records.
• A “match” does not prove the person is tax compliant.
• It does not replace W-9 collection or other due diligence.
• Some records may not return a match even if the information is correct.

Common use cases

• verifying vendors before issuing 1099s
• checking contractors and freelancers
• validating payee records in accounting systems
