IRS Cracking Down on Type of Income Earned by Millions - Here's How to Protect Yourself

More Americans than ever are looking for ways to make extra money on the side, whether that means driving for a rideshare app, selling goods online, or freelancing after hours. But as side hustles grow, so does scrutiny from the IRS. With new funding and upgraded technology, the agency is paying closer attention to income that once slipped under the radar. If you earn money outside your regular job, it's critical to understand what has changed.

Here's what you need to know before tax season arrives.

Side hustles have become increasingly common

Earning extra income outside of a primary job has become a normal part of many Americans' financial lives. According to LendingTree's 2025 Side Hustle Survey, nearly 40% of Americans have a side hustle, and 61% of those who have one say it's essential to afford their everyday life. For some, side gig earnings represent a meaningful monthly supplement rather than just occasional spending money.

From driving for rideshare apps to freelancing online or selling products through digital marketplaces, income streams are more diversified than ever. Economic pressure, higher costs of living, and the desire for financial flexibility have fueled this trend. However, the IRS is getting more serious about tracking side gig income.

The IRS is cracking down on unreported side gig income

If you assume small amounts of income are too minor for the IRS to notice, that assumption may no longer hold. Funding from the Inflation Reduction Act of 2022 gave the IRS additional resources to modernize its systems and deploy advanced data analytics tools.

In practical terms, enforcement is increasingly automated. Sophisticated software can match reported income against third-party forms and digital payment data. For freelancers and gig workers, this means discrepancies are more likely to be flagged quickly, often before you even realize there is a problem.

These upgrades do not target only high earners. The focus includes underreported business and gig income across income levels.

Even small side gig income can trigger problems

There is a common misconception that only large sums of money must be reported. In reality, the IRS generally requires you to file and pay self-employment taxes if your net earnings from self-employment reach $400 or more in a year.

The definition of gig work is quite broad. For example, income from ride-sharing services, short-term rentals, online marketplaces, freelance design projects, errand services, tutoring, or consulting all typically count as taxable income. Even selling products online for profit can qualify. Many people are surprised by how much they owe when filing their return. And gig work isn't the only situation where unexpected tax bills can pop up.

Banks and payment processors also generate reporting documents under certain thresholds. Peer-to-peer platforms like PayPal or Venmo may issue Form 1099-K if transactions exceed established reporting levels. While thresholds have changed over time, the underlying rule remains — taxable income must be reported whether or not you receive a form.

Also, don't forget about cash earnings: large cash transactions over $10,000 trigger specific reporting requirements under federal law, and repeated unexplained deposits can draw attention and potentially result in an audit.

How you could be impacted and steps to take to avoid an IRS audit

If you earn income outside a traditional paycheck, it is your responsibility to track and report it accurately. The safest approach is to maintain detailed records of all revenue, including digital payments, bank transfers, and cash. Keeping organized documentation reduces stress and strengthens your position if questions arise.

It is equally important to track legitimate business expenses, such as mileage, supplies, marketing costs, and home office expenses. Proper deductions can lower your taxable income and ensure you are not overpaying. Consider setting aside a portion of each side hustle payment for estimated taxes so you are not caught off guard at filing time.

If your side income is consistent, quarterly estimated tax payments may also be required. Consulting a tax professional can help clarify your obligations and ensure compliance with evolving rules.

Bottom line

Side hustles have become a normal part of American life, but unreported income is no longer easy to overlook. With expanded funding and improved technology, the IRS is better equipped to identify discrepancies between what taxpayers report and what third parties disclose.

If you make cash on the side, keeping accurate records, reporting every dollar of taxable income, and understanding your filing requirements can protect you from penalties. A little organization today can prevent costly problems tomorrow and help you stay focused on building income the right way.
