 Preguntas frecuentes

What is self-employment tax and why do side hustlers pay it?

Self-employment tax covers Social Security and Medicare contributions. When you work a regular W-2 job, your employer pays half of these taxes. As a self-employed side hustler, you pay both halves — a combined 15.3% on 92.35% of your net earnings. The Social Security portion (12.4%) applies up to the wage base limit ($176,100 in 2025), while Medicare (2.9%) has no cap.
When are quarterly estimated tax payments due?

The IRS requires estimated tax payments four times a year: April 15, June 15, September 15, and January 15 of the following year. If your total tax liability from self-employment exceeds $1,000 for the year, you generally need to make these payments to avoid underpayment penalties.
Can I deduct business expenses from my side hustle income?

Yes. Ordinary and necessary business expenses directly related to your side hustle reduce your net self-employment income. Common deductions include vehicle mileage, home office costs, supplies, software subscriptions, professional development, and marketing expenses. Lower net income means lower self-employment tax and income tax.
How does the 50% self-employment tax deduction work?

The IRS allows you to deduct half of your self-employment tax from your adjusted gross income. This mimics the employer-side FICA deduction that W-2 employees receive. It does not reduce your self-employment tax itself, but it lowers your taxable income for federal income tax purposes, resulting in a smaller overall tax bill.
