Corporate Exemption From 1099 Reporting: Exceptions and Penalties

The corporate exemption from 1099 reporting lets payers skip filing an information return when the recipient is a C corporation, an S corporation, or an LLC taxed as either. The exemption is broad but not absolute. Payments for legal services, gross proceeds paid to attorneys, medical and health care payments, cash purchases of fish for resale, substitute dividend payments, and service payments made by federal executive agencies must be reported even when the payee is a corporation.

Why the Exemption Exists and Who Qualifies

Treasury Regulation § 1.6041-3(p)(1) relieves payers from filing information returns when the recipient is a corporation. Corporations already carry their own reporting obligations, annual tax filings, and in many cases external audits, so layering 1099s on top would generate paperwork without adding oversight.

The exemption covers both C corporations and S corporations. It also covers any limited liability company that has elected to be taxed as either type. An LLC taxed as a partnership or as a disregarded entity does not qualify and must receive a 1099 like any other non-corporate payee.

Confirming Corporate Status With Form W-9

The only reliable way to confirm that a payee qualifies is to collect a completed Form W-9 before making payment. The form captures the payee’s legal name, taxpayer identification number, and federal tax classification, certified under penalty of perjury.¹

The classification appears on Line 3a of the current form. The payee checks a box for C corporation, S corporation, partnership, individual, trust, or LLC. An LLC must also enter a letter code showing its tax treatment: “C” for C corporation, “S” for S corporation, or “P” for partnership.² An LLC marked “C” or “S” is treated the same as any other corporation for 1099 purposes. An LLC marked “P,” or one that leaves the classification blank, cannot be treated as a corporation.

Keep every W-9 on file for as long as it remains in effect and for at least three years after the last tax year in which you relied on it. If the IRS questions a missing 1099, a properly completed W-9 showing corporate status is your primary defense.³

Payments to Corporations You Still Have to Report

Several categories of payment override the corporate exemption entirely. Even when the W-9 shows the payee is a corporation, you must file an information return for these.

Attorney Fees for Legal Services

Any payment to an attorney in connection with legal services must be reported, whether the attorney operates as a sole practitioner, partnership, or corporation.⁴ If you pay $600 or more to an attorney or law firm for work performed for your business, report the amount in Box 1 of Form 1099-NEC.⁵

Gross Proceeds Paid to an Attorney

Payments of $600 or more to an attorney that include funds belonging to the attorney’s client, such as a settlement check where the firm is a co-payee, go in Box 10 of Form 1099-MISC.⁵ The gross proceeds rule under Section 6045(f) applies whether or not the legal services were performed for the payer.⁴ If you issue a check to a law firm to settle a claim brought by someone else, you still have a reporting obligation.

Medical and Health Care Payments

Payments to incorporated medical providers, including hospitals, clinics, laboratories, and individual practitioners, are reported on Form 1099-MISC in Box 6 when they reach the reporting threshold. For 2026, that threshold is $2,000, up from $600, because these payments fall under Section 6041, which was amended by the One Big Beautiful Bill Act.⁶ A business paying a corporate medical practice $1,500 during 2026 for employee physicals no longer triggers a 1099, whereas the same payment in 2025 would have.

Cash Payments for Fish Purchased for Resale

If your business buys fish or other aquatic life for resale, you must report total cash payments of $600 or more made during the year to anyone in the business of catching fish, even when that person operates through a corporation. Report the annual total in Box 11 of Form 1099-MISC.⁵ Only cash payments trigger the rule. Payments by check or electronic transfer to a corporate fishing operation do not.

Other Reportable Payments to Corporations

Substitute payments in lieu of dividends or tax-exempt interest of $10 or more, in Box 8 of Form 1099-MISC.⁶
Payments by a federal executive agency to a corporation for services, in Box 1 of Form 1099-NEC.⁵

Payment card and third-party network transactions are reported on Form 1099-K by the payment processor, not by you as the payer. For 2026, the 1099-K threshold remains at more than $20,000 in aggregate payments and more than 200 transactions.⁶

How the 2026 Threshold Change Affects the Exceptions

Starting with payments made after December 31, 2025, the general reporting threshold under Section 6041 rose from $600 to $2,000. The change was enacted by the One Big Beautiful Bill Act, applies to Forms 1099-MISC, 1099-NEC, W-2, and W-2G, and will adjust for inflation in future years.⁷

The practical impact on the corporate exceptions varies by category. Medical and health care payments to corporations now use the $2,000 floor, which removes many smaller payments from the reporting requirement.⁶ Attorney fees and fish purchases still show a $600 threshold in the 2026 IRS instructions because they are governed by separate code sections.⁵

Backup Withholding on the Same Exception Categories

Corporations are generally exempt from backup withholding, the 24% tax a payer must withhold from reportable payments when a payee fails to provide a valid taxpayer identification number. That exemption does not extend to the same categories that override the 1099 exemption. If a corporate payee fails to furnish a TIN on its W-9, you must withhold 24% from medical and health care payments, attorney fees, gross proceeds paid to an attorney, and payments for services made by a federal executive agency.⁸

This catches businesses off guard. A corporation that has always been exempt from withholding on ordinary payments can suddenly trigger a 24% obligation if it provides legal or medical services and its TIN is missing or flagged as incorrect by the IRS. The best prevention is refusing to process payments until you have a complete, signed W-9 on file.

Penalties for Missing a Required 1099

Failing to file a required 1099 for a corporate payee that falls into an exception category carries per-return penalties that scale with how late you are. For returns due in 2026, the IRS assesses:

$60 per return corrected within 30 days of the due date.
$130 per return corrected after 30 days but by August 1.
$340 per return filed after August 1 or not filed at all.
$680 per return for intentional disregard, with no annual cap.⁹

Annual caps limit total exposure for businesses that aren’t acting intentionally. The general ceiling is $3,000,000 per year. Businesses with average annual gross receipts of $5,000,000 or less over the prior three years qualify for a lower maximum of $1,000,000.¹⁰ The same penalty structure applies for failing to furnish the payee with their copy of the form.

The concentrated risk sits in attorney fees. Businesses routinely pay law firms large sums and assume the corporate exemption covers them. Getting the W-9 right up front and flagging attorney and medical payees in your accounting system is much cheaper than cleaning up a missed 1099 on a $50,000 legal bill.
