Quick answer
- Compare the 1099 with your records to find the mistake.
- Ask the payer for a corrected 1099 (the same form with the “CORRECTED” box checked). They file it with the IRS too.
- If they won’t fix it in time, report the correct amount on your return and keep documentation explaining the difference.
- If the IRS later sends a CP2000 notice, respond with your records.
You report what you actually received. The 1099 is the payer’s report, not the final word.
Common 1099 mistakes
| Mistake | Typical cause |
|---|---|
| Amount too high | Includes reimbursed expenses, a payment sent in January of the next year, or card payments also reported on a 1099-K |
| Amount too low | A missed payment or a payment recorded in the wrong year |
| Payment made in December, received in January | The payer counts it when sent; you (cash basis) count it when received |
| Wrong name or TIN | Old W-9, typo, or your SSN used instead of your EIN |
| Wrong form | A 1099-MISC instead of a 1099-NEC |
| Duplicate | The same income reported on a 1099-NEC and a 1099-K |
| Not your income | Identity theft or a mix-up with another contractor |
Step 1: reconcile with your records
List every payment from that payer during the year, with dates, from your bank statements and invoices. Pinpoint the exact difference and why. That makes the conversation with the payer quick.
Step 2: ask for a corrected form
Email the client’s accounts payable team:
Hi [name], the 2026 Form 1099-NEC I received shows [$X] in box 1. My records show payments totalling [$Y] (list attached). The difference is [reason, e.g., the January 3, 2027 payment for invoice 2026-031]. Could you issue a corrected 1099-NEC? Thank you.
The payer issues a new form marked “CORRECTED” and files it with the IRS. For a 1099-K error, contact the platform (PayPal, Stripe, Etsy), not the client.
Step 3: if you don’t get a correction in time
Don’t hold your return hostage to the payer. File by the deadline:
- Report your actual gross receipts on Schedule C, line 1. The IRS matches your total, so the aim is a total you can explain.
- If the 1099 is too high: one approach is to include the full 1099 amount in gross receipts and subtract the incorrect portion on line 2 (returns and allowances) or as a clearly labelled adjustment, so the 1099 figure is visibly accounted for. Ask your tax preparer which method they prefer.
- If the 1099 is too low: report your real, higher income.
- Keep the email to the payer, your payment list and bank statements.
Duplicate reporting (1099-NEC and 1099-K)
If a client paid you through PayPal or card and also sent a 1099-NEC, the income appears twice. Report it once. Ask the client to correct the 1099-NEC, since card and payment app payments shouldn’t be on it, and keep a reconciliation.
Wrong name or TIN
Send the client an updated W-9 and ask for a corrected form. A mismatched TIN can lead to 24% backup withholding on future payments and IRS notices for the payer.
If you never worked for the payer
A 1099 from a company you don’t know can be a sign of identity theft. Contact the payer, and if it isn’t resolved, report it to the IRS using Form 14039 (Identity Theft Affidavit). Don’t report income you never received.
What if the IRS sends a CP2000?
A CP2000 is a proposal, not a bill. It means the IRS’s 1099 records don’t match your return. Respond by the deadline:
- Agree if it’s right, and pay.
- Disagree, in whole or in part, with a letter explaining the difference and copies of your records (the corrected 1099, bank statements, emails).
Most mismatches caused by a payer’s mistake are resolved this way.
Worked example
Chen’s 1099-NEC from an agency shows $24,000. His records show $21,000: a $3,000 payment for December work arrived on January 4, 2027, so it’s 2027 income for him. The agency won’t issue a correction before he files.
He reports the $24,000 from the form and subtracts $3,000 with an explanation (“payment received 1/4/2027, reported in 2027”). His net gross receipts from the agency are $21,000. He reports the $3,000 on next year’s return and keeps the bank statement showing the January deposit.
Frequently asked questions
Is the client required to correct a 1099?
Yes. Payers must file corrected returns when they discover errors, but they may be slow.
Can I just ignore a wrong 1099?
No. The IRS will see the mismatch. Report the right amount and document the difference.
Should I file Form 1040-X if a corrected 1099 arrives after I filed?
Only if it changes what you reported. If you already reported the correct amount, no amendment is needed.
What if the 1099 includes expense reimbursements?
Report the full amount as income and deduct the related expenses on Schedule C, or ask the client to correct it if the reimbursements were made under an accountable plan.
