If you get a fake 1099, or a 1099 reporting income you never earned, do not put that income on your tax return. What you do next depends on which of three things is actually happening: identity theft, a legitimate payer’s mistake, or a company misclassifying you as an independent contractor. Each has a different fix, and starting in 2026 the reporting threshold for nonemployee compensation on Form 1099-NEC rises from $600 to $2,000, so a small-dollar form from a payer you don’t recognize is an immediate warning sign.1Internal Revenue Service. 2026 Publication 1099
Red Flags That Tell You the Form Is Fake
The clearest sign of fraud is a 1099 for work you never did, from a company you’ve never heard of. That usually means someone is using your Social Security number or taxpayer identification number to file bogus returns under your name. Other signals are subtler.
Check the payer block first. Every legitimate 1099 has to include the payer’s name, address, and TIN, along with your matching information.2Internal Revenue Service. General Instructions for Certain Information Returns – Section: Recipient Names and Taxpayer Identification Numbers A missing TIN, or a payer name that doesn’t match anyone you’ve worked for, is a problem. If you need to contact the payer, look up their number independently rather than calling anything printed on the form itself.
Look at how the form arrived. The IRS never sends tax documents through email attachments, text links, or social media messages. A 1099 that reaches you through any of those channels is a phishing attempt.3Internal Revenue Service. Report Fake IRS, Treasury or Tax-Related Emails and Messages Don’t click, don’t open the attachment.
Compare the dollar figure to your own records. A form showing $15,000 when you only earned $1,500 from that payer is either a data-entry error or part of a scheme to inflate your reported income and file a fraudulent refund claim in your name.
Fake 1099-K forms tied to payment apps are their own category. Under the One Big Beautiful Bill Act, the 1099-K reporting threshold reverted to over $20,000 in payments across more than 200 transactions.4Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One Big Beautiful Bill A 1099-K for transactions well below that, or for personal transfers like splitting rent, is issued in error. The IRS says to contact the payment processor directly and immediately when that happens.5Internal Revenue Service. Actions to Take if a Form 1099-K Is Received in Error or With Incorrect Information
If It’s Identity Theft: Who to Report It To
Once you’re confident the form is fraudulent, reporting isn’t optional. The IRS already has a copy of every 1099 filed under your SSN, and its automated matching system will eventually flag you for underreporting if you stay quiet.
File Form 14039 With the IRS
Form 14039, the Identity Theft Affidavit, tells the IRS your identity has been compromised and prompts them to flag your account.6Internal Revenue Service. Reporting Identity Theft Expect a wait: the IRS has been processing Form 14039 submissions with significant delays, with forms received as far back as mid-2024 still in the queue in recent updates.7Internal Revenue Service. Processing Status for Tax Forms
Forward Phishing Messages and Report to TIGTA
If the fake 1099 came by email or text, forward the message to phishing@irs.gov before you delete it.3Internal Revenue Service. Report Fake IRS, Treasury or Tax-Related Emails and Messages Also file with the Treasury Inspector General for Tax Administration, which investigates tax fraud targeting taxpayers. TIGTA takes reports online or by phone at 1-800-366-4484.8U.S. Treasury Inspector General for Tax Administration. Submit a Complaint
Notify the SSA and File a Police Report
If your SSN is on the form, contact the Social Security Administration. Unauthorized use of your number can distort your earnings record and affect future benefit calculations. File a police report locally, too. You’ll need the report number if you later apply for an extended fraud alert on your credit.
File Your Return With Only Real Income
Do not include the fake income. File your return with the income you actually earned and attach a written explanation describing the fraudulent form and the reports you’ve made. Keep the original fake 1099, and keep copies of every complaint, letter, and call log. The IRS specifically recommends maintaining records of all correspondence related to the identity theft.9Internal Revenue Service. Identity Theft Guide for Individuals
If You’ve Already Received a CP2000 Notice
You may still get a CP2000 notice even after reporting the fraud. It’s an automated letter flagging a mismatch between the 1099 income the IRS has on file under your SSN and what you reported. It proposes additional tax and gives you a deadline.10Internal Revenue Service. Topic No. 652, Notice of Underreported Income – CP2000
Miss the deadline and the IRS can assess the proposed balance as final, which is much harder to undo. When the mismatch is from identity theft, include a completed Form 14039 with your response.11Internal Revenue Service. Understanding Your CP2000 Series Notice Attach whatever you have: the police report, your TIGTA complaint, and any records showing you never did the work or received the payment. You can respond by mail, fax, or the IRS Document Upload Tool, using the contact information on the notice.10Internal Revenue Service. Topic No. 652, Notice of Underreported Income – CP2000
If It’s a Real Payer With Wrong Numbers
Sometimes the 1099 comes from a company you actually worked with, but the amount is wrong, the box is wrong, or your information is tangled with someone else’s. Contact the payer and ask for a corrected form.12Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect
If they won’t cooperate or you can’t reach them by the end of February, call the IRS at 800-829-1040 with your name, address, SSN, and the payer’s information. The IRS will contact the payer and request a correction on your behalf.12Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect
Don’t hold your return hostage waiting. If the corrected form doesn’t arrive by the filing deadline, file with the numbers you know are accurate. If a corrected form shows up after you’ve filed, use Form 1040-X to amend.12Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect
If You Got a 1099 But You Were Really an Employee
A separate problem, easy to confuse with a fake 1099, is a 1099-NEC from a company that set your schedule, told you how to do the work, and otherwise treated you as an employee. That’s worker misclassification. It costs you money because you pay the full 15.3% self-employment tax yourself instead of splitting Social Security and Medicare (7.65% each) with an employer.13Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
The IRS looks at three areas: behavioral control (does the company direct how you do the work?), financial control (does it control how you’re paid and whether expenses are reimbursed?), and the nature of the relationship (written contract, benefits, ongoing work).14Internal Revenue Service. Worker Classification 101 – Employee or Independent Contractor No single factor decides it.
To get an official ruling, file Form SS-8 for a determination of your worker status.15Internal Revenue Service. About Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding Meanwhile, still file your return on time. Use Form 8919 to pay only your share of Social Security and Medicare taxes rather than the full self-employment amount. You’re eligible if you performed services for a firm, believe you were an employee, and the firm didn’t withhold your share of those taxes.16Internal Revenue Service. IRS Form 8919 – Uncollected Social Security and Medicare Tax on Wages Form 8919 also gets your Social Security earnings record properly credited.
If the IRS rules in your favor, the business has to file corrected employment tax returns and issue a W-2 reflecting your real status.17Internal Revenue Service. Information Guide for Employers Filing Form 941 or Form 944 If you used Form 4852 as a substitute W-2 while the determination was pending, the corrected W-2 replaces it.18Internal Revenue Service. Using Form 4852 When Missing the Form W-2 or 1099-R
Lock Things Down So It Doesn’t Happen Again
Once your tax information is out there, one fraudulent form is rarely the end of the risk. Two steps make the next attempt much harder.
Get an IRS Identity Protection PIN
An Identity Protection PIN is a six-digit number that blocks anyone from filing a federal return under your SSN without it. You don’t have to be a confirmed victim; anyone with an SSN or ITIN can enroll. The fastest route is through your IRS online account. If you can’t verify online and your adjusted gross income is under $84,000 ($168,000 married filing jointly), you can apply on Form 15227 and verify by phone.19Internal Revenue Service. Get an Identity Protection PIN The PIN changes each year and must appear on your return for it to be accepted.
Freeze Your Credit or Set a Fraud Alert
Tax identity theft often points to broader exposure. A credit freeze blocks anyone, including you, from opening new credit until you lift it. It’s free, lasts until you remove it, and has to be set up with all three bureaus: Equifax, Experian, and TransUnion.20Federal Trade Commission. Credit Freezes and Fraud Alerts
If a full freeze feels heavy, an initial fraud alert is lighter. It runs one year, is renewable, and only requires contacting one bureau, which then notifies the other two. An extended fraud alert runs seven years but requires an FTC identity theft report at IdentityTheft.gov or a police report.20Federal Trade Commission. Credit Freezes and Fraud Alerts Both are free.
