The Complete Guide to 1099 Taxes

As an independent contractor, you are responsible for both halves of FICA taxes — the 6.2% employee portion AND the 6.2% employer portion of Social Security, plus 1.45% + 1.45% for Medicare. This totals 15.3% on top of your income tax, which is why freelancers are often shocked by their first tax bill. On $85,000 net income, self-employment tax alone is approximately $12,000.

The good news: you can deduct the employer half of SE tax (7.65%) from your gross income, reducing your income tax. You can also deduct legitimate business expenses — home office, equipment, software, mileage (67 cents/mile for 2025), health insurance premiums, and retirement contributions. These deductions can reduce your effective tax rate significantly. Set your freelance rate to cover taxes with our Freelance Rate Calculator.

Quarterly Estimated Tax Payments

Unlike W-2 employees who have taxes withheld automatically, 1099 workers must pay estimated taxes quarterly. If you owe more than $1,000 at filing time, the IRS charges an underpayment penalty. The safe harbor rule: pay at least 100% of last year's tax liability (110% if AGI > $150,000) through quarterly payments and you avoid penalties regardless of how much you actually owe.

The four quarterly deadlines are: April 15 (Q1), June 15 (Q2), September 15 (Q3), and January 15 (Q4). Many freelancers set aside 25-30% of every payment into a separate tax savings account. Check your overall income picture with our Paycheck Calculator.

People Also Ask

How much should I set aside for taxes as a freelancer?

Home office (simplified: $5/sq ft up to 300 sq ft), internet/phone (business %), equipment, software subscriptions, mileage (67¢/mile 2025), health insurance premiums, retirement contributions (SEP-IRA up to 25%), professional development, and business insurance.
Should I form an LLC or S-Corp?
At approximately $50K+ net income, an S-Corp can save $3,000-$8,000/year in self-employment tax by paying yourself a "reasonable salary" and taking the rest as distributions. Consult a CPA for your specific situation.
