Looking for ways to earn extra cash? Side hustles are everywhere, promising flexible hours and quick money. But while many side gigs seem harmless, some can get you into hot water with the IRS if you’re not careful. The line between a legit side hustle and a tax headache is thinner than you might think. Whether you’re driving for a rideshare app, selling crafts online, or renting out your spare room, it’s easy to overlook the tax rules that apply. Ignoring these rules can lead to penalties, audits, or even legal trouble. Here’s what you need to know to keep your side hustles on the right side of the law.
1. Cash-Only Gigs That Skip Reporting
It’s tempting to pocket cash from babysitting, dog walking, or lawn care and call it a day. After all, who’s going to know? The IRS, that’s who. Any income you earn, even if it’s paid in cash, is legally required to be reported on your tax return. Failing to do so is considered tax evasion, and the penalties can be steep. Many people assume small cash jobs fly under the radar, but the IRS has ways to track unreported income, especially if clients claim your services as a business expense. Always keep records of your earnings, no matter how small, and report them at tax time.
2. Under-the-Table Freelance Work
Freelancing is a popular side hustle, but some individuals attempt to evade taxes by accepting payments “under the table.” This might mean getting paid via Venmo, PayPal, or even gift cards, with no official paperwork. However, digital payment platforms are now required to report transactions exceeding $600 to the IRS, making it more difficult to hide income. If you’re freelancing—writing, graphic design, tutoring, or consulting—treat it like a real business. Track your income, save receipts, and set aside money for taxes. Failing to do so can result in back taxes, interest, and penalties. The gig economy is under increasing scrutiny, so don’t assume you’re flying under the radar.
3. Renting Out Your Home Without Reporting
Platforms like Airbnb and Vrbo make it easy to rent out a room or your entire home for extra cash. However, many hosts are unaware that rental income is taxable. Even if you only rent out your place a few times a year, you may need to report that income and pay taxes on it. There are some exceptions—like the “14-day rule,” which lets you rent your home for up to 14 days a year tax-free—but most people don’t qualify. If you provide services like cleaning or breakfast, you may also be required to pay self-employment tax. Failing to follow these rules can result in a surprise tax bill or an audit.
4. Selling Goods Online Without Tracking Profits
Selling crafts on Etsy, flipping items on eBay, or running a small Shopify store can be a fun and profitable side hustle. However, many sellers are unaware that profits from these activities are taxable. Even if you think of it as a hobby, the IRS may see it as a business if you’re making money. You’re required to report your income and may be able to deduct expenses, but you need good records to do so. Payment processors like PayPal and Stripe now send 1099-K forms for sales over $600, so the IRS will know about your earnings. Failing to report profits can lead to penalties and interest. Treat your online sales like a real business from day one.
5. Driving for Rideshare or Delivery Apps Without Withholding
Driving for Uber, Lyft, DoorDash, or Instacart is a classic side hustle. However, many drivers are unaware that they’re considered self-employed, which means taxes aren’t automatically withheld from their pay. You’re responsible for paying both income tax and self-employment tax, which covers Social Security and Medicare. If you don’t set aside money throughout the year, you could face a big tax bill in April. You may also need to make quarterly estimated tax payments. Keep detailed records of your earnings and expenses, including mileage, to maximize your deductions and avoid surprises.
6. Ignoring Local Business Licenses and Sales Tax
Some side hustles, such as selling homemade food, crafts, or offering services, require local business licenses or the collection of sales tax. Skipping these steps may seem harmless, but it can lead to fines or even result in your business being shut down. Each state and city have its own rules, so be sure to check what’s required before you start. Collecting and remitting sales tax is especially important if you sell physical goods. Don’t assume you’re too small to matter—local governments are cracking down on unlicensed businesses and unpaid taxes.
Keep Your Side Hustle Legit and Stress-Free
Side hustles are a great way to boost your income, but they come with real tax responsibilities. The IRS and local governments are paying closer attention to gig workers and small business owners. By keeping accurate records, reporting all your income, and understanding the specific rules for your side hustle, you can avoid costly mistakes and retain your extra earnings. Don’t let a simple oversight turn your side hustle into a tax nightmare—take the time to get it right from the start.
