Report flags / 1099-NEC
NUMBERS“The payer's tax ID isn't a valid EIN”
What this flag on a 1099-NEC means, why it matters, and what to check.
What it means
The payer's TIN is written as an employer identification number (12-3456789), but its first two digits are a prefix the IRS has never issued.
Why it matters
Real EINs come from the IRS's fixed list of prefixes. An invented number often doesn't.
Ordinary explanations
- A typo in a form filled in by hand.
What to check
Confirm the payer exists and paid the applicant: look the business up yourself and call it. Ask the applicant for the IRS wage and income transcript (free at irs.gov or with Form 4506-T), which lists W-2 amounts as the employer reported them.
A flag is a reason to verify with the source, not proof. Apply the same steps to every applicant.
