Quick Answer
Online course income is reported as self-employment income on Schedule C if you're regularly teaching courses as a business. If you earned over $400 from courses in 2026, you'll owe self-employment tax (15.3%) plus regular income tax. For example, $5,000 in course income adds roughly $1,530 in total taxes for someone in the 22% bracket.

How do I report online course income on my tax return?
Online course income is considered self-employment income and must be reported on Schedule C (Profit or Loss from Business) if you're regularly creating and selling courses. This applies whether you sell through platforms like Udemy, Teachable, or your own website.
The key factor is whether you're doing this as a business activity rather than a hobby. If you're consistently creating courses, marketing them, and trying to make a profit, the IRS considers this a business—even if it's a side hustle alongside your W-2 job.
Example: $5,000 in online course income
Let's say you earned $5,000 from online courses in 2026:
Self-employment tax calculation:
Income tax calculation:
Total additional tax: $689 + $990 = $1,679
Business deductions you can claim
As a course creator, you can deduct legitimate business expenses on Schedule C:
Quarterly estimated tax payments
Since online course income isn't subject to withholding, you may need to make quarterly estimated tax payments if you expect to owe $1,000 or more in tax for the year.

Forms you'll need to file
What you should do
1. Track all course income throughout the year
2. Keep receipts for business expenses
3. Set aside 25-30% of course income for taxes
4. Consider making quarterly payments if earning over $1,000
5. Use our quarterly estimator to calculate payments
Key takeaway: Online course income over $400 triggers self-employment tax of 15.3% plus regular income tax. Set aside 25-30% of course earnings for taxes and track all business expenses to reduce your tax burden.

Best for creators who occasionally sell courses but primarily focus on other content monetization
Is this a business or just extra income?
If you're primarily a content creator who occasionally sells a course, the tax treatment depends on frequency and intent. Selling one course per year might be reported as "other income" on Form 1040, but if you're regularly creating courses as part of your content strategy, it's business income.
Platform-specific considerations
Udemy and Teachable: These platforms typically send 1099-NEC forms if you earned over $600. They may also withhold taxes for international students.
Your own website: You're responsible for tracking all income, even small amounts. Payment processors like Stripe or PayPal will send 1099-K forms for transactions over $5,000.
When it's hobby vs. business
The IRS looks for profit motive. If you're creating courses to build your personal brand rather than generate significant income, it might be considered a hobby. However, hobby income is still taxable—you just can't deduct expenses against it.
Business indicators:
Key takeaway: Even occasional course sales count as taxable income. If you're doing it regularly as part of your content business, report on Schedule C to claim deductions.
Key Takeaway: Even occasional course sales are taxable income, but regular course creation qualifies as a business where you can deduct expenses on Schedule C.

Best for people who just started teaching online courses and aren't sure about tax implications
Starting your first online course? Here's what to expect
Many new course creators are surprised by the tax implications. Unlike your W-2 job where taxes are automatically withheld, course income comes with no withholding—meaning you owe both regular income tax AND self-employment tax.
Your first $400 threshold
Once you earn $400 or more from course sales, you must file Schedule SE and pay self-employment tax. This is separate from income tax and covers your Social Security and Medicare contributions.
Example for a beginner:
Set up good habits early
1. Open a separate business checking account for course income
2. Track expenses immediately using apps like QuickBooks Self-Employed
3. Set aside 30% of income for taxes in a separate savings account
4. Keep all receipts for equipment, software, and business expenses
Common beginner mistakes
Key takeaway: Start with good record-keeping habits from day one—track income, save for taxes, and keep business expenses separate to make tax time much easier.
Key Takeaway: New course creators should set aside 30% of income for taxes, track all business expenses, and file Schedule C once they earn over $400.
