Yes, referral fees are taxable. The IRS treats them as ordinary income to whoever receives them, whether the payment arrives as cash, a check, a gift card, or merchandise, because federal law defines gross income as “all income from whatever source derived” and lists fees and commissions among the clearest examples.1Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined What varies is whether you also owe self-employment tax, whether a 1099-NEC gets issued, and whether the payer can deduct the expense.
How the Recipient Is Taxed
Referral income is taxed at your ordinary marginal rate, the same as wages. There is no capital gains treatment and no lower bracket for referral payments. The fee stacks on top of your other income for the year, which means a sizable payment can push part of your earnings into a higher bracket.
If you earn referral fees regularly as part of a trade or business, the income is also subject to self-employment tax of 15.3% — 12.4% for Social Security and 2.9% for Medicare — once your net self-employment earnings reach $400 for the year.2Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) You report the income on Schedule C and calculate the self-employment tax on Schedule SE.3Internal Revenue Service. Instructions for Schedule C (Form 1040) Half of the self-employment tax is deductible on your return.
Hobby Income vs. Business Income
Not every referral triggers self-employment tax. If you make a referral once or twice a year without any real effort to build a referral business, the IRS may treat the payment as hobby income, which is subject to regular income tax only. You’d report it on Schedule 1 (Form 1040), line 8j.
The tradeoff is real. Hobby expenses are effectively not deductible. Section 183 allows hobby deductions only up to the activity’s gross income and only as miscellaneous itemized deductions, and the Tax Cuts and Jobs Act suspended those deductions starting in 2018.4Office of the Law Revision Counsel. 26 U.S. Code 183 – Activities Not Engaged in for Profit The IRS looks at factors including how much time and effort you put in, whether you depend on the income, and whether you’ve turned a profit in at least three of the last five years. If you earn referral fees consistently and treat the activity like a business, Schedule C is the right home.
Gift Cards and Other Non-Cash Rewards
A referral fee doesn’t need to be cash to be taxable. Gift cards, merchandise, event tickets, and other property count as income at their fair market value on the date of transfer. If you’re wondering whether a small gift card from a bank or credit card company is too minor to count, it isn’t. The IRS is clear that cash and cash equivalents like gift cards are never excludable as de minimis fringe benefits.5Internal Revenue Service. De Minimis Fringe Benefits A $50 gift card for referring a friend to a new checking account is $50 of taxable income, and it belongs on your return whether or not a 1099 arrives.
Estimated Tax Payments
Referral fees usually come with no tax withheld. If you expect to owe $1,000 or more for the year after withholding and refundable credits, the IRS expects quarterly estimated payments.6Internal Revenue Service. 2026 Form 1040-ES Missing them triggers an underpayment penalty even if you pay in full at filing.
For 2026, the quarterly due dates are April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027. You can skip the January payment if you file your 2026 return by February 1, 2027, and pay the full balance then.6Internal Revenue Service. 2026 Form 1040-ES A safe harbor applies if you pay at least 100% of the prior year’s tax liability (110% if your adjusted gross income exceeded $150,000) or 90% of the current year’s liability, whichever is smaller.7Internal Revenue Service.

What the Payer Has to Do
If you pay someone $600 or more in referral fees during a calendar year, you must report those payments on Form 1099-NEC. The IRS instructions specifically list “fee-splitting or referral fees” as a reportable payment type.8Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (04/2025) The threshold is the total paid to that recipient over the year, not per transaction.
Before making the first payment, collect a Form W-9 from the recipient. The W-9 captures the Taxpayer Identification Number you need for the 1099-NEC.9Internal Revenue Service. About Form W-9, Request for Taxpayer Identification Number and Certification If the recipient fails to provide a TIN, you must withhold 24% of each payment as backup withholding and remit it to the IRS.10Internal Revenue Service. Backup Withholding
The 1099-NEC must be furnished to the recipient and filed with the IRS by January 31 of the following year. There is no automatic extension for 1099-NEC filings.8Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (04/2025)
One common exception: you generally do not need to issue a 1099-NEC for referral fees paid to a C corporation or S corporation, including an LLC treated as either for tax purposes. Payments to attorneys for legal services are the main exception and must be reported regardless of entity type.8Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (04/2025) Ask for a W-9 up front; the form identifies the recipient’s entity type and tells you whether a 1099 is required.
Deducting Referral Fees You Pay
Referral fees you pay are generally deductible as an ordinary and necessary business expense under Section 162, which allows deductions for expenses that are “common and accepted” in your industry and “helpful and appropriate” for the business.11Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses The IRS can deny the deduction in three main situations: when the fee is unreasonable relative to industry norms, when you failed to file the required 1099-NEC, and when the payment was for a personal rather than business purpose.
Reporting and deduction go together. Skip the 1099 and the IRS can disallow the write-off even though the underlying payment was legitimate. Keep the written referral agreement, proof of payment, W-9 forms, and copies of filed 1099-NECs for at least three years from the date you filed the return claiming the deduction.12Internal Revenue Service. How Long Should I Keep Records
Penalties on Both Sides
If You’re the Payer
Failing to file a correct 1099-NEC on time carries per-form penalties that escalate:
- Up to 30 days late: $60 per form
- 31 days late through August 1: $130 per form
- After August 1 or never filed: $340 per form
- Intentional disregard: $680 per form
These apply separately for failing to file with the IRS and for failing to furnish the statement to the recipient, so one missed 1099 can generate two penalties.13Internal Revenue Service. Information Return Penalties
If You’re the Recipient
If you leave referral income off your return, the IRS can add an accuracy-related penalty of 20% of the underpaid tax attributable to negligence or a substantial understatement, on top of the tax and interest you already owe.14Office of the Law Revision Counsel. 26 U.S. Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Unreported referral income is easy for the IRS to catch, because the payer’s 1099-NEC creates a matching record. When your return omits income a 1099 reported, the automated matching system generates a notice.
When Referral Fees Are Illegal
Some industries restrict or prohibit paying for referrals, and the tax treatment gets worse when a payment crosses that line. The federal Anti-Kickback Statute makes it a felony to pay or receive anything of value in exchange for referring patients covered by Medicare, Medicaid, TRICARE, or other federal healthcare programs.15HHS Office of Inspector General. General Questions Regarding Certain Fraud and Abuse Authorities Violations carry fines of up to $100,000 and up to 10 years in prison per offense.16Office of the Law Revision Counsel. 42 USC 1320a-7b – Criminal Penalties for Acts Involving Federal Health Care Programs
Even if a referral fee is illegal, the recipient still owes income tax on it. The payer, however, loses the deduction. Section 162 denies business expense deductions for any payment that is an illegal bribe or kickback under federal or state law, and the statute defines “kickback” to include “a payment in consideration of the referral of a client, patient, or customer.”17Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Payments tied to Medicare or Medicaid referrals are separately singled out as non-deductible under the same provision.
