If you freelance in the US — as a designer, developer, writer, consultant, or any other self-employed professional — tax season works very differently from a regular salaried job. Nobody withholds taxes from your payments. Nobody sends you a W-2. The IRS expects you to handle it yourself.
This guide walks through every step, using the latest 2025 IRS figures, so you know exactly what to file, what to pay, and what you can deduct.
1. Who counts as a freelancer for tax purposes?
The IRS uses the term self-employed, not freelancer. You are considered self-employed if you:
- Earn income from clients or customers rather than a traditional employer
- Receive payments reported on a 1099-NEC form instead of a W-2
- Operate your own business, even informally as a sole proprietor
This covers full-time freelancers, part-time side hustlers, and independent contractors. If you earned $400 or more from self-employment in a year, you are required to file a federal return.
2. What taxes do freelancers pay in 2025?
As a freelancer, you typically owe two types of federal tax:
| Tax type | Rate (2025) | What it covers |
|---|---|---|
| Self-employment tax | 15.3% | Social Security (12.4%) + Medicare (2.9%) |
| Federal income tax | 10% – 37% | Based on taxable income and filing status |
| State income tax | 0% – 13.3% | Varies by state; some states have none |

Why is self-employment tax 15.3%?
When you work for an employer, they pay half your Social Security and Medicare taxes (7.65%) and you pay the other half. As a freelancer, you are both employer and employee — so you pay the full 15.3%.
The good news: you can deduct half of this tax (7.65%) from your gross income before calculating federal income tax, which reduces your overall tax bill.
3. What is Schedule C?
Schedule C (Profit or Loss from Business) is the IRS form where you report freelance income and business expenses. It attaches to your personal Form 1040.
- Gross income — total payments received from all clients
- Business expenses — legitimate costs of running your freelance work
- Net profit — gross income minus expenses (this is what gets taxed)
4. Quarterly estimated taxes
Freelancers must pay taxes four times a year directly to the IRS — these are called estimated tax payments. If you expect to owe $1,000 or more for the year, you are generally required to make these payments. Underpaying triggers a penalty.

5. Top deductions for freelancers
Deductions reduce your Schedule C net profit — meaning you pay less self-employment tax and less income tax. These are the most valuable deductions available to US freelancers:
| Deduction | What qualifies |
|---|---|
| Home office | Space used regularly and exclusively for business. Simplified method: $5/sq ft up to 300 sq ft ($1,500 max) |
| Software & subscriptions | Work tools — Adobe, Notion, Slack, project management apps, etc. |
| Hardware & equipment | Laptop, monitor, camera — the business-use percentage |
| Internet & phone | The percentage used for business purposes |
| Health insurance premiums | 100% deductible if you pay your own premiums and are not eligible for employer-sponsored insurance |
| Professional development | Courses, books, certifications, conferences relevant to your work |
| Business travel | Transportation and accommodation for client meetings. Standard mileage rate 2025: 70 cents/mile |
| Retirement contributions | SEP-IRA: up to 25% of net earnings, max $70,000 for 2025 |
| Half of SE tax | 50% of your self-employment tax is deductible — applied automatically on Form 1040 |

6. 2025 standard deduction amounts
After your Schedule C net profit is calculated, you reduce taxable income further with the standard deduction (or itemized deductions, whichever is higher). The 2025 amounts — updated by the One Big Beautiful Bill Act — are:
| Filing status | 2025 standard deduction | vs. 2024 |
|---|---|---|
| Single | $15,750 | +$750 |
| Head of household | $23,625 | +$1,125 |
| Married filing jointly | $31,500 | +$1,500 |
