Before You Cash That First Payout: The Tax Reality Check Every New Online Instructor Needs

The first payout notification is a rush. Maybe it's $340 from Udemy, maybe $2,100 from Teachable, maybe a handful of Stripe deposits from your own website. Either way, it lands in your account and it feels like the universe just handed you a gift.

Then your tax pro asks how much you made, and you realize nobody ever told you the rules. "I thought the platform handled that" is the sentence that starts a lot of expensive conversations. So we talked to a couple of tax professionals and put together the pre-launch reality check new instructors keep skipping.

First: The Platform Is Not Your Accountant

"The number one misconception I see is people assuming the platform took care of taxes," says Dana Whitfield, an enrolled agent in Austin who works with creators and gig workers. "Platforms process payments. Some withhold backup withholding in rare cases. But the tax liability on your teaching income? That's yours. Full stop."

When you teach through Udemy, Skillshare, Outschool, or your own site, you're generally operating as a sole proprietor by default. That means:

• 1099-K and 1099-NEC forms may arrive (platforms issue 1099-Ks if you cross reporting thresholds, which have been shifting — in 2024 and 2025 the IRS threshold has been phasing down toward $2,500 and eventually $600, though enforcement has bounced around). Regardless of forms, all income is taxable and reportable, even if you never see a 1099.
• Self-employment tax of 15.3% covers Social Security and Medicare, on top of regular income tax. "People budget for income tax and forget SE tax entirely," Whitfield says. "That's the April surprise."
• Quarterly estimated taxes are expected once you expect to owe $1,000 or more. Miss them and you may owe penalties — even if you pay everything by April.

Deductions: The Part Nobody Uses Enough

Here's the good news. As a business, you can deduct ordinary and necessary expenses:

• Course platform subscriptions and hosting fees
• Microphone, camera, lighting, editing software
• Portion of home internet and a home office (using the simplified or actual method)
• Course creation costs — stock footage, music licenses, that whiteboard you bought at Staples
• Professional development, including courses you took to improve your teaching

"The home office deduction scares people, but the simplified method is genuinely simple," says Marcus Lee, a CPA in Chicago who specializes in side businesses. "$5 per square foot up to 300 square feet. If you teach from a dedicated room, take it."

Just keep receipts. Apps like QuickBooks Self-Employed or even a Google Drive folder of screenshots work fine.

LLC: Helpful, But Not Magic

Should you form an LLC? "It depends," says Lee. "An LLC separates business liabilities from personal assets and can look more professional. It does not change your federal taxes by default — a single-member LLC is taxed exactly like a sole proprietor unless you elect otherwise."

Costs vary wildly by state: around $50 in Colorado, $500 in California (plus that infamous $800 annual franchise tax). If you're teaching a low-risk skill — watercolor, not financial advice — a sole proprietorship is often fine to start. If you're scaling, taking on clients, or offering anything resembling professional guidance, talk to a pro about an LLC and possibly an S-corp election once profits get meaningful (many CPAs suggest it around $40,000–$60,000 in net profit).

Sales Tax: The Weird One

Digital products occupy a strange corner of US tax law. States treat online courses differently — some, like Texas and New York, generally tax digital courses; others don't. The 2018 South Dakota v. Wayfair decision means states can require you to collect sales tax based on your customers' locations once you cross their economic nexus thresholds (commonly $100,000 in sales or 200 transactions).

"Most new instructors selling through a marketplace don't need to worry — the marketplace facilitator handles it," Lee notes. "But if you sell directly through your own site with Stripe or PayPal, the burden can fall on you. That's when you talk to a professional or use a tool like TaxJar or Stripe Tax."

The Pre-Launch Checklist

Before your course goes live:

1. Open a separate business bank account. Commingling funds is the root of most bookkeeping pain.
2. Pick a bookkeeping system — even a spreadsheet with income and expense columns.
3. Set aside 25–30% of every payout for taxes. Automate the transfer.
4. Save every receipt, digital or paper.
5. Check your state's sales tax rules for digital products, especially if selling direct.
6. Calendar quarterly estimated tax deadlines: April 15, June 15, September 15, January 15.
7. Decide on LLC vs. sole proprietorship — and revisit the decision once revenue grows.
8. Budget an hour with a tax professional before your first full year closes. It's the cheapest insurance you'll ever buy.

Teaching online is one of the most accessible side hustles in America right now. A little paperwork on the front end makes sure the money you earn is actually the money you keep.
