Frequently Asked Questions
How much should I set aside for taxes?
Most self-employed workers should set aside 25-30% of their net income for taxes. This covers both self-employment tax (15.3%) and federal income tax. Use the calculator above to get your exact percentage based on your income level and deductions.
What is self-employment tax?
Self-employment tax is 15.3% of your net self-employment earnings. It consists of 12.4% for Social Security (up to $184,500 in 2026) and 2.9% for Medicare (no cap). This is the equivalent of both the employee and employer portions of FICA taxes. You can deduct half of your SE tax when calculating your income tax.
When are quarterly estimated tax payments due?
For 2026, quarterly estimated payments are due: Q1 on April 15, 2026; Q2 on June 15, 2026; Q3 on September 15, 2026; and Q4 on January 15, 2027. Missing these deadlines can result in underpayment penalties.
What can I deduct as a self-employed worker?
Common deductions include: vehicle mileage ($0.70/mile in 2026), home office ($1,500 simplified method), health insurance premiums, phone and internet (business %), equipment (Section 179), supplies, professional development, and software subscriptions. Platform-specific deductions vary—rideshare drivers can deduct car washes and phone mounts, while Airbnb hosts can deduct cleaning and furnishings.
Do I need to pay self-employment tax if I made less than $400?
No. If your net self-employment earnings are less than $400 for the year, you do not owe self-employment tax. However, you may still need to report the income on your tax return if your total income exceeds the filing threshold.
