Whether you’re a full-time freelancer or earned $500 on a side project, you need to report it. Here’s exactly how to do it without overpaying or triggering an audit.
Quick answer: Report all freelance income on Schedule C of your tax return. Deduct all business expenses to reduce taxable income. You’ll owe income tax + 15.3% self-employment tax on net profit. Make quarterly estimated payments if you’ll owe $1,000+ at tax time.
How Freelance Income Is Taxed
| Tax Component | Rate | On What |
|---|---|---|
| Federal income tax | 10–37% | Net profit (after deductions) |
| Self-employment tax | 15.3% (12.4% SS + 2.9% Medicare) | 92.35% of net profit |
| State income tax | 0–13.3% | Net profit |
| Additional Medicare tax | 0.9% | Net SE income over $200K |

Freelance Tax Example
This example separates true Schedule C business expenses (which reduce net profit and therefore SE tax) from above-the-line personal deductions like health insurance and retirement contributions (which reduce AGI but are calculated on Schedule 1, not Schedule C, and do NOT reduce the SE tax base).
| Item | Amount |
|---|---|
| Gross freelance income | $75,000 |
| Home office deduction | -$2,400 |
| Computer/equipment | -$2,000 |
| Software/subscriptions | -$1,200 |
| Internet (50% business) | -$600 |
| Phone (60% business) | -$720 |
| Net profit (Schedule C) | $68,080 |
| Self-employment tax (92.35% × 15.3%) | $9,618 |
| Half of SE tax (above-the-line deduction) | -$4,809 |
| Health insurance (above-the-line deduction) | -$7,200 |
| Solo 401(k) employee contribution (2026 limit) | -$24,500 |
| Adjusted gross income (before standard deduction) | $31,571 |
| Standard deduction (2026, single) | -$16,100 |
| Taxable income (excludes QBI deduction for simplicity) | $15,471 |
| Federal income tax (2026 brackets) | ~$1,609 |
| Total tax on $75K gross (SE tax + income tax) | ~$11,227 (~15.0%) |
This example excludes the QBI deduction (up to 20% of qualified business income), which would further lower taxable income and total tax for most freelancers — see the QBI deduction guide. Aggressive retirement and health insurance contributions reduce your income tax bill but not your self-employment tax, since SE tax is calculated on Schedule C net profit before those above-the-line deductions apply.
Record Keeping Requirements
| What to Keep | How Long | Why |
|---|---|---|
| Income records (invoices, 1099s, bank statements) | 7 years | IRS audit window |
| Expense receipts | 7 years | Prove deductions |
| Mileage log | 7 years | IRS requires contemporaneous record |
| Home office measurements | Duration of deduction | Calculate deduction |
| Asset purchase records | Life of asset + 7 years | Depreciation records |
| Tax returns | Indefinitely | Reference for future years |
Bottom Line
Freelance tax filing is straightforward once you know the process: track income and expenses throughout the year, pay quarterly estimates, and file Schedule C with your annual return. The key to keeping taxes low is maximizing legitimate deductions — home office, health insurance, retirement contributions, and equipment can slash your taxable income. Just remember that self-employment tax is based on your Schedule C net profit, not your final taxable income after personal deductions. Don’t fear the self-employment tax — most of it is building your own Social Security benefit.
