If you don’t file a 1099 you were required to file, the IRS charges a per-form penalty that starts at $60 and climbs to $340 for each form you never submit, and those penalties stack across every contractor or payee you missed. If you’re on the other side and received a 1099 but left the income off your return, you owe the underlying tax, interest that compounds daily, and a 20% accuracy-related penalty on the underpayment. The consequences depend on which side of the form you’re on and how quickly you fix the problem.
Penalty Amounts for a Payer Who Didn’t File
The IRS charges an escalating per-return penalty based on how late the form is. For returns due in 2026, the inflation-adjusted amounts are:1Internal Revenue Service. Rev. Proc. 2024-40
- $60 per return if you file within 30 days of the due date
- $130 per return if you file more than 30 days late but on or before August 1
- $340 per return if you file after August 1 or never file at all
Every missed form counts separately. A business that skipped 1099s for 50 contractors and never corrects the problem is looking at $17,000 in penalties before any tax question is even raised.
The total annual penalty is capped for non-intentional failures. Businesses with average annual gross receipts above $5 million face a maximum of $4,098,500 for returns due in 2026; smaller businesses (average gross receipts of $5 million or less) are capped at $1,366,000.1Internal Revenue Service. Rev. Proc. 2024-40 The lower per-return tiers carry their own sub-caps, which is why fixing the problem quickly matters even if the overall ceiling looks far away.
The filing deadlines that start this clock are worth knowing. For tax year 2025, both Form 1099-NEC and Form 1099-MISC require the recipient’s copy by January 31. The IRS copy is due February 28 on paper or March 31 electronically.2Internal Revenue Service. General Instructions for Certain Information Returns (2026) Any business filing 10 or more information returns (counting W-2s) must file electronically.3Internal Revenue Service.

When the IRS Calls It Intentional Disregard
If the IRS decides you deliberately ignored the filing requirement, the penalty structure changes. The fine becomes the greater of an inflation-adjusted per-return minimum or 10% of the total dollar amount that should have appeared on the return.4Office of the Law Revision Counsel. 26 USC 6721 – Failure to File Correct Information Returns There is no annual cap. A business that systematically avoids issuing 1099s to keep contractors off the IRS’s radar can accumulate penalties without limit.
If You Received a 1099 and Didn’t Report It
Many people asking this question are on the receiving end: a 1099 arrived, the income is real, and the return went in without it. The IRS almost certainly has a matching copy of that form.
Leaving reported income off your return is treated as negligence, which triggers a 20% accuracy-related penalty on the portion of tax you underpaid. You also owe the underlying tax and interest that compounds daily from the original due date of the return. The IRS specifically lists “not including income on your tax return that was shown in an information return, like income reported on Form 1099” as an example of negligence.5Internal Revenue Service. Accuracy-Related Penalty
The negligence standard reaches broadly. Under federal law, it includes “any failure to make a reasonable attempt to comply” with the tax code, and “disregard” covers careless, reckless, or intentional behavior.6Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments Deliberately omitting income you know was reported to the IRS goes well beyond carelessness.
How the IRS Finds Out
The IRS runs an Automated Underreporter program that compares every information return filed by employers, banks, and businesses against income reported on individual returns. When a 1099 shows income missing from a payee’s return, the system generates a CP2000 notice.7Internal Revenue Service. Understanding Your CP2000 Series Notice It’s a proposed adjustment rather than a bill, but ignoring it leads to an automatic assessment.
On the payer side, the gap surfaces differently. Businesses that deduct contractor payments but never file the matching 1099s can trigger questions during an examination. When agents request bank statements and payment records, the absence of the required information returns raises doubts about the deductions tied to those payments, and a narrow inquiry can widen into a broader review.
The Time Limit Problem for Unfiled Forms
Penalties for a 1099 that was filed late or with errors must generally be assessed within three years of the due date or actual filing date, whichever is later. For a form that was never filed, there is no statute of limitations. The IRS can assess penalties at any time.8Internal Revenue Service. IRM 20.1.7 Information Return Penalties That alone is a strong reason to file late instead of not at all.
Requesting Penalty Relief
The IRS can waive information return penalties if the failure was due to reasonable cause rather than willful neglect. You generally have to show two things: that you acted responsibly before and after the failure, and that either significant mitigating factors were present or events beyond your control caused the failure.8Internal Revenue Service. IRM 20.1.7 Information Return Penalties
Acting responsibly means doing what a reasonably careful person would do: requesting filing extensions when practical, trying to prevent foreseeable problems, and correcting the failure promptly, which the IRS generally reads as within 30 days. Carelessness and forgetfulness do not qualify.8Internal Revenue Service. IRM 20.1.7 Information Return Penalties
Factors that help include being a first-time filer of the particular form, a clean compliance history, good-faith reliance on erroneous IRS guidance, or the loss of records to a fire or other casualty. If a payee gave you an incorrect TIN or refused to provide one despite your requests, that also supports a reasonable cause argument.9Internal Revenue Service. Penalty Relief for Reasonable Cause The IRS may also grant a first-time abatement administratively when you call to request relief.
Filing a Late 1099
Filing late is always better than not filing. The per-return penalty is lower the sooner you act, and submitting the form closes the open-ended assessment window.
You need the payee’s legal name, current mailing address, and a valid Taxpayer Identification Number (a Social Security Number for individuals, an Employer Identification Number for businesses).10Internal Revenue Service. U.S. Taxpayer Identification Number Requirement This information should have been collected on Form W-9 before you made payments; if it wasn’t, request one now.
Pick the correct form. Form 1099-NEC covers payments of $600 or more for services performed by someone who isn’t your employee. Form 1099-MISC covers rent, royalties, prizes, medical payments, and other categories of miscellaneous income.11Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC Using the wrong form creates a second filing error.
The IRS Information Returns Intake System (IRIS) is the primary electronic filing portal and accepts late filings and corrections.12Internal Revenue Service. E-file Information Returns With IRIS Electronic filing gives you an immediate receipt confirming submission, which is worth having if the IRS later questions whether you filed. If you’re filing fewer than 10 information returns total and choose paper, you must use official IRS forms; Copy A of the 1099 and Form 1096 (the transmittal summary) are processed by optical scanning equipment and cannot be printed from the IRS website in standard black-and-white.13Internal Revenue Service. General Instructions for Certain Information Returns (2025) Order official forms through the IRS online ordering system, and remember that Form 1096 totals the amounts across all your paper 1099s and must accompany them when mailed.14Internal Revenue Service. About Form 1096, Annual Summary and Transmittal of U.S. Information Returns
Keep copies of every form you submit along with any electronic confirmation receipts. Verify all dollar amounts against your bank records before submitting, because an incorrect amount on a late filing creates a second penalty event instead of resolving the first.
