The Situation

The Side Hustle Tax Reality

Side hustle income is different from employee income in one critical way: nobody withholds taxes for you. Self-employment income is subject to both income tax and self-employment tax (covering Social Security and Medicare contributions that employers normally split with employees). Without proactive tax management, a profitable side hustle can create a painful April surprise.

Side hustle income is not a bonus. It is gross revenue that requires tax management from the first dollar.
