When it comes to filing year-end information returns like Forms 1099 and W-2, accuracy matters. One of the most common — and costly — mistakes is a mismatch between a payee’s name and Taxpayer Identification Number (TIN). That’s where TIN Matching comes in. It’s a simple but powerful IRS tool that helps businesses prevent errors, avoid penalties, and stay compliant.
What Is TIN Matching?
TIN Matching is an IRS system that allows payers to verify whether a payee’s name and TIN (usually a Social Security Number or Employer Identification Number) match IRS records before filing information returns.
You can use TIN Matching for:
-
Form 1099-NEC
-
Form 1099-MISC
-
Form 1099-INT
-
Form W-2 (indirectly, through the SSA, not IRS TIN Matching)
By validating data upfront, businesses can catch typos, mismatches, and invalid TINs — reducing the chance of CP2100 notices and backup withholding obligations.
How TIN Matching Works
There are two main options:
1. Interactive TIN Matching
-
Best for one-off verifications.
-
Enter a single name/TIN combination and receive instant feedback.
2. Bulk TIN Matching
-
Upload a file with multiple names and TINs.
-
Receive a downloadable report of matches and mismatches.
Why TIN Matching Matters
Using TIN Matching before submitting 1099s or W-2s can:
-
Reduce the risk of penalties.
-
Save time by avoiding IRS rejections.
-
Protect your business from costly compliance issues.
