The $600 threshold for 1099 reporting creates a dangerous misconception for side hustlers. Just because a platform doesn't send you a tax form doesn't mean you skip taxes entirely.
Self-employment tax kicks in once you earn $400 or more from any side work, regardless of whether you receive a 1099. The IRS tracks this amount separately from the $600 reporting threshold. This affects millions of people driving for Uber, freelancing on Fiverr, selling items online, or taking on gig work.
Self-employment tax covers Social Security and Medicare taxes. When you work a regular job, your employer splits these costs with you. As a self-employed person, you pay both sides yourself, typically around 15.3% of your net earnings. On $400 in side income, that's roughly $60 owed to the IRS.
The confusion stems from conflating two different rules. The $600 threshold determines when 1099-NEC or 1099-MISC forms get issued to you and reported to the IRS. But you must pay self-employment tax on all earnings above $400 even if nobody files a 1099 on your behalf.
Failure to report and pay creates real penalties. The IRS assesses interest on unpaid taxes plus accuracy-related penalties of 20% or more. An audit becomes more likely if your reported income doesn't match platform records the IRS already has.
Side hustlers should track all earnings from day one, including platforms that don't issue 1099s. Keep records of income and deductible expenses like equipment, software subscriptions, or mileage. When April rolls around, report self-employment income on Schedule C and calculate SE tax on Schedule SE.
The $400 rule applies each year, so $350 one year and $250 the next both fall
