This month, the IRS Taxpayer Advocate Service published "March Madness, NIL, and (Tax) Brackets"—a blog post that cuts directly to what families are struggling with. Across the country, college athletes are earning thousands of dollars in NIL income during the highest-visibility period of the year. And most of them don't understand the tax consequences.
At the same time, Congress is asking the same question. With a deadline of April 10, 2026, Chairman Cassidy and the Senate are requesting stakeholder input on whether the current NIL system is working. One key concern: many athletes are caught off guard by self-employment tax obligations.
This guide explains the IRS guidance, shows you how the tax brackets work for NIL income, and walks through what families need to do before April 15, 2027—when taxes are due.
The IRS Taxpayer Advocate Just Weighed In: "March Madness, NIL, and (Tax) Brackets"
The Taxpayer Advocate Service published guidance in March 2026 specifically addressing NIL income during March Madness season. The TAS acts as an independent voice within the IRS, and their guidance is taken seriously by tax professionals and the IRS itself.
The core message: NIL income is real income, it's taxable, and the IRS is watching.
Here's what the TAS emphasized:
- Self-employment tax applies. NIL income is self-employment income. That means 15.3% self-employment tax (Social Security + Medicare), plus federal income tax, plus state income tax.
- Reporting is mandatory and tracked. Schools, brands, and collectives report NIL payments. The IRS has visibility into these deals before athletes file taxes.
- Quarterly estimated taxes kick in above $1,100. If an athlete earns more than $1,100 in self-employment income during the year, they owe quarterly estimated taxes. Failure to pay can trigger penalties and interest.
- March Madness creates timing complexity. Tournament income is earned in March but taxed in the current year. Athletes need to account for this in their quarterly estimates.
The message is clear: treat NIL income like business income from day one, because the IRS does.
The $2.6 Billion NIL Economy: Where the Money Actually Goes
To understand the tax burden, you need to understand the scope of NIL. In 2026, the NIL economy is worth approximately $2.6 billion nationally. But the breakdown reveals something important: most of that money doesn't flow directly to athletes.
- Direct athlete payments: ~$1.8 billion (the amount flowing through collectives, schools, and brands directly to athletes' pockets)
- Infrastructure and intermediaries: ~$400 million (platform fees, compliance costs, collective management)
- Administrative and legal overhead: ~$400 million (NCAA reporting, state compliance, attorney fees)
The key number for tax purposes: approximately $1.8 billion flows directly to athletes. That $1.8 billion is fully taxable income in the hands of the recipients.
At the top end, Arch Manning leads NIL valuations with a deal valued at $5.4 million. But most athletes earn far less. The median NIL athlete receives between $5,000 and $50,000 annually. During March Madness, a tournament-bound athlete might earn $10,000–$100,000 depending on school visibility and brand partnerships.
How NIL Income Is Taxed: The Self-Employment Bracket
This is where families get confused. When you hear "tax bracket," you're usually thinking about income tax brackets (10%, 12%, 22%, etc.). But NIL income faces a hidden bracket: the self-employment tax bracket.
Self-employment tax is 15.3%. This is fixed, regardless of income level. It covers Social Security (12.4%) and Medicare (2.9%). Unlike a regular job where your employer pays half of this, athletes earning NIL income as self-employed pay the full 15.3%.
Here's the math for a typical March Madness athlete earning $25,000 in tournament-related NIL income:
- NIL income: $25,000
- Self-employment tax (15.3%): $3,825
- Federal income tax (22% federal bracket): $5,500
- State income tax (varies by state, assume 5%): $1,250
- Total tax owed: $10,575
- Net after taxes: $14,425
That $25,000 deal nets roughly $14,425. The difference—42%—goes to taxes. Many athletes don't realize this until April 15 when the bill arrives.
The Tax Bracket System for Different NIL Income Levels
Here's what the actual tax brackets look like for student athletes earning NIL income in 2026, assuming they have no other income and claim the standard deduction:
$5,000 NIL Income
Self-employment tax: $765 | Federal income tax: $0–$500 | State tax: $0–$250 | Total tax: $765–$1,515 | Net: $3,485–$4,235
$15,000 NIL Income
Self-employment tax: $2,295 | Federal income tax: $1,500–$2,000 | State tax: $0–$750 | Total tax: $3,795–$5,045 | Net: $9,955–$11,205
$25,000 NIL Income
Self-employment tax: $3,825 | Federal income tax: $5,500 | State tax: $0–$1,250 | Total tax: $9,325–$10,575 | Net: $14,425–$15,675
$50,000 NIL Income
Self-employment tax: $7,650 | Federal income tax: $11,000 | State tax: $0–$2,500 | Total tax: $18,650–$21,150 | Net: $28,850–$31,350
The pattern is consistent: for every dollar of NIL income, expect to owe 35–42% in taxes across federal, state, and self-employment obligations.
Congress Wants Answers by April 10, 2026
The Senate is asking a critical question: is the current NIL system working fairly for athletes?
Chairman Cassidy has requested stakeholder input by April 10, 2026. The questions on the table include:
- Are NIL deals transparent? Are athletes aware of full tax implications before signing?
- Are collectives properly reporting payments to the IRS and athletes?
- Should the government provide tax relief or clarification for student-athlete income?
- Are international athletes on F-1 visas being treated fairly (most are currently excluded from NIL)?
- Should schools be required to provide tax education before athletes earn NIL income?
This deadline is significant because Congress is considering legislative action. If you or your athlete is affected by NIL taxation, stakeholder input on April 10 could influence whether Congress addresses this gap.
April 10 Stakeholder Deadline
Congress is requesting written input on the NIL system by April 10, 2026. If you believe the current tax treatment of NIL income is unfair or if your athlete has experienced tax surprises, this is the moment to submit feedback to your Congressional representatives. The deadline is firm.
International Athletes on F-1 Visas: The NIL Tax Gap
One population is largely excluded from NIL: international students on F-1 visas. The IRS rules on non-immigrant taxation and employment restrictions have created a gap where most F-1 athletes cannot earn NIL income.
Here's why:
- F-1 visa rules restrict on-campus employment to university jobs only
- NIL income is considered off-campus self-employment
- Athletes and schools worry that pursuing NIL deals violates visa conditions and could trigger deportation
- As a result, most international athletes are excluded from the $1.8 billion NIL payment pool
This affects thousands of athletes—particularly in basketball, hockey, and soccer where international recruitment is heavy. A Canadian hockey player or a Brazilian soccer prospect cannot legally earn NIL income in the United States, even though their U.S. domestic competitors can.
Congress's April 10 stakeholder deadline includes questions about whether this gap should be closed through legislative action.
What You Need to Do Before April 15, 2027 (Tax Day)
If your athlete earned NIL income in 2026, here's the action plan:
Step 1: Document All NIL Income (By April 1, 2026)
Collect statements from every source:
- School/athletic department NIL payments
- Collective payments (collectives must report deals to NIL Go within 5 business days)
- Direct brand deals or endorsement payments
- Social media payments (if applicable)
Request written statements showing gross payment amounts and payment dates. You'll need this for filing.
Step 2: Set Aside 40% for Taxes (By April 1, 2026)
Do this immediately. Move 40% of all NIL income received into a high-yield savings account labeled "2026 Tax Reserve." Do not spend this money. This is your tax liability fund.
Example: $25,000 in tournament NIL income = $10,000 set aside for taxes.
Step 3: Identify Deductible Business Expenses (By May 15, 2026)
NIL income allows deductions for legitimate business expenses:
- Content creation equipment (camera, microphone, lighting for social media content)
- Website hosting and domain registration for NIL brand
- Professional tax preparation and legal fees for NIL contracts
- Accountant or bookkeeping services
- Social media management tools (if you use them for NIL promotion)
- Home office deduction (proportional space used for NIL business)
Do not deduct:
- General athletic training or conditioning
- College tuition or living expenses
- Personal apparel (unless specifically required by a brand deal and deducted as ordinary business expense)
Deductions reduce your taxable income. A $25,000 NIL income with $2,000 in legitimate deductions is reported as $23,000 net self-employment income. That saves roughly $3,060 in federal and self-employment taxes.
Step 4: Hire a Tax Professional Experienced with Athlete NIL Income (By June 15, 2026)
Find a CPA or enrolled agent who works with college athletes. When interviewing, ask directly: "Have you filed taxes for student athletes with NIL self-employment income?" Listen for specifics about quarterly estimated taxes, self-employment forms (Schedule C, Schedule SE), and multi-state tax issues.
A quality athlete-tax professional will cost $800–$2,500 depending on complexity. This is an investment that prevents thousands in IRS penalties.
Step 5: File Your 2026 Tax Return and Pay (By April 15, 2027)
Your tax return will include:
- Form 1040 (Individual Income Tax Return): Reports your overall tax situation
- Schedule C (Profit or Loss from Business): Reports NIL income and deductible expenses
- Schedule SE (Self-Employment Tax): Calculates the 15.3% self-employment tax
- Form 8829 (Home Office Deduction): If claiming home office expenses
- State tax return: Most states tax NIL income (varies by state)
Your tax professional will prepare all of these. Your role is to provide accurate income documentation and expense records.
Why Self-Employment Tax Is Different (And Why It Matters)
Many athletes and parents confuse regular income tax with self-employment tax. Here's the key difference:
Regular employee income: Your employer withholds taxes. You get a W-2. Taxes are paid throughout the year automatically.
Self-employment income (NIL): No withholding. You receive gross payment. You must pay quarterly estimated taxes yourself. If you don't, the IRS charges penalties and interest.
For NIL income above $1,100 annually, quarterly estimated taxes are required:
- Q1 (April 15): Pay 1/4 of estimated annual tax
- Q2 (June 15): Pay 1/4 of estimated annual tax
- Q3 (September 15): Pay 1/4 of estimated annual tax
- Q4 (January 15 of following year): Pay 1/4 of estimated annual tax
If an athlete earns $25,000 in March Madness income, they should estimate $10,575 in total tax and pay $2,644 (25%) by June 15, another $2,644 by September 15, and the remainder by January 15.
Many athletes skip quarterly payments and pay a lump sum on April 15 of the following year. The IRS allows this, but it's riskier. If income comes in unevenly (concentrated in March Madness), estimates are harder to predict. Work with a tax professional.
The International Athlete Question: Congress Is Listening
International students on F-1 visas represent a major gap in the current NIL system. These athletes often have the highest market value—elite soccer players, hockey prospects, basketball internationals—but they're excluded from earning NIL income.
The reason is structural. F-1 visa rules prohibit off-campus self-employment. NIL deals are off-campus self-employment. Therefore, international athletes cannot legally pursue them.
This is one of the specific questions Congress is asking in the April 10 stakeholder deadline: should legislative action clarify or expand NIL eligibility for F-1 athletes?
If you're an international athlete or the parent of one, and you believe this policy should change, April 10 is when Congress is listening.
Bottom Line: March Madness Spotlight Means IRS Spotlight
March Madness focuses attention on college athletes. It also focuses attention on NIL income. The IRS knows about these deals. Congress is asking questions. The Taxpayer Advocate Service published guidance. Schools are reporting payments.
The athletes who handle NIL tax obligations well are the ones who treat income like a business from day one: separate accounts, documented expenses, professional tax advice, and reserved funds for tax liability.
The athletes who get surprised by tax bills are the ones who treat NIL income like a paycheck, spend it immediately, and hope taxes somehow resolve themselves.
If your athlete earned NIL income during the 2026 tournament season, don't wait until April 2027 to think about taxes. The time to plan is now. Set aside 40% immediately. Find a tax professional. Document your income. Track expenses. Prepare for April 15, 2027.
March Madness is over. Tax day isn't.
