How to report online course income on your tax return
Online course income is considered self-employment income and must be reported on Schedule C (Profit or Loss from Business). This applies whether you sell through platforms like Udemy, Teachable, or directly through your own website.
You'll report the gross income you received, then subtract business expenses to calculate your net profit. That net profit gets added to your W-2 income on your Form 1040, and you'll also owe self-employment tax on it.
Example: $15,000 in course sales with expenses
Let's say you earned $15,000 selling courses in 2026 while working your full-time job:

Deductible expenses:
Net profit: $7,500 - $4,700 = $2,800

If this is your first year earning money from online courses, don't panic — it's actually pretty straightforward once you understand the basics.

Best for people managing course income alongside other freelance work
Managing course income with other side hustles
If you're already doing freelance work or have other 1099 income, adding course sales is actually easier tax-wise because you're already filing Schedule C.
You can combine all your side hustle income and expenses on one Schedule C, or file separate ones if you want to track profitability by business type.
Strategic considerations for multiple income streams
Shared expenses: If you use the same home office, computer, or internet for courses and other freelance work, you can allocate the costs across both businesses or claim them all on your primary Schedule C.
Quarterly payment planning: Course income tends to be more predictable than project-based freelancing, making it easier to estimate quarterly payments. Use steady course revenue to cover the unpredictable tax burden from your other 1099 work.
Business structure decisions: Once your combined side hustle income hits $30,000-50,000, consider forming an LLC or electing S-Corp status to potentially save on self-employment taxes.
Time management for tax prep
Keep separate tracking for each income stream during the year, even if you'll combine them on Schedule C. This helps you understand which activities are most profitable and makes business decisions easier.
Key takeaway: Course income integrates well with other freelance work for tax purposes, and the predictable nature of course sales can help stabilize your quarterly tax planning.
Key Takeaway: Course income combines easily with other freelance income on Schedule C, and its predictable nature helps with quarterly tax planning across all your side hustles.
