Freelancer Taxes in the US: The Complete 2026 Guide

If you freelance, consult, drive for a rideshare platform, or run any self-employed business in the United States, you are responsible for tracking your own taxes. Unlike W-2 employees, no employer withholds anything on your behalf. The upside: you can deduct every legitimate business expense and significantly reduce what you owe. This guide covers everything you need to know for the 2025 tax year (filed in 2026).

Disclaimer: Tax law changes annually. Always verify current rates and rules at irs.gov or with a qualified CPA before filing.

Who Needs to File as Self-Employed?

You must file Schedule SE and report self-employment income if your net earnings from self-employment are $400 or more in a tax year. This applies to freelancers, independent contractors, gig workers, sole proprietors, and single-member LLCs.

You will receive a 1099-NEC from any client who paid you $600 or more during the year. However, you must report all self-employment income regardless of whether you receive a 1099 - the IRS gets copies of all 1099s and cross-references them against your return.

Schedule C: Your Business Tax Return

Self-employed individuals report business income and expenses on Schedule C (Profit or Loss from Business), which is attached to your Form 1040. Schedule C calculates your net profit - the figure that flows into your income tax calculation and self-employment tax calculation.

Net profit = Total revenue − Total deductible business expenses

The lower your net profit, the less tax you owe. This is why tracking every legitimate expense matters.

Self-Employment Tax

Self-employed individuals pay self-employment (SE) tax of 15.3% on net earnings, which covers Social Security (12.4%) and Medicare (2.9%). For 2025, Social Security tax applies to the first $176,100 of net self-employment earnings. There is no cap on the 2.9% Medicare portion.

The good news: you can deduct half of your SE tax (the employer-equivalent portion) as an above-the-line deduction on your Form 1040, reducing your adjusted gross income (AGI).

• Net SE earnings × 92.35% = SE tax base (the 7.65% reduction mirrors the employer deduction W-2 employees receive)
• SE tax base × 15.3% = SE tax owed
• SE tax ÷ 2 = deductible amount on Form 1040

Quarterly Estimated Tax Payments

Because no employer withholds taxes for you, the IRS requires self-employed individuals to pay estimated taxes quarterly. Failing to do so results in an underpayment penalty, even if you pay in full by April 15.

2026 quarterly due dates (for the 2025 tax year):

• Q1 (Jan–Mar): April 15, 2025
• Q2 (Apr–May): June 16, 2025
• Q3 (Jun–Aug): September 15, 2025
• Q4 (Sep–Dec): January 15, 2026

Use Form 1040-ES to calculate and submit estimated payments. A safe harbour rule: pay at least 100% of last year's tax liability (110% if AGI exceeded $150,000) and you will avoid the underpayment penalty regardless of your final bill.

The Biggest Tax Deductions for US Freelancers

1. Mileage and Vehicle Expenses

The IRS standard mileage rate for 2025 is 70 cents per mile for business use (check irs.gov for updated 2026 rates). Track every business mile: client visits, networking events, post office runs for business packages, and supply pickups all qualify. You may alternatively deduct actual vehicle expenses (fuel, insurance, maintenance, depreciation) based on your business-use percentage - whichever method yields a larger deduction.

TaxSort's GPS mileage tracker automatically logs every trip and calculates your deduction, so you never undercount miles.

2. Home Office Deduction

If you use part of your home regularly and exclusively for business, you can deduct it. The simplified method allows $5 per square foot (up to 300 sq ft, so a maximum of $1,500). The regular method deducts the business-use percentage of actual home expenses: rent/mortgage interest, utilities, insurance, and repairs.

3. Health Insurance Premiums

Self-employed individuals who are not eligible for employer-sponsored health insurance through a spouse can deduct 100% of health, dental, and vision insurance premiums for themselves and their family as an above-the-line deduction. This is one of the most valuable deductions exclusive to the self-employed.

4. Retirement Contributions

Contributing to a SEP-IRA allows you to deduct up to 25% of net self-employment income, with a 2025 maximum of $70,000. A Solo 401(k) allows even higher combined contributions as both employee and employer. Retirement contributions reduce your taxable income dollar-for-dollar - one of the most powerful tax planning tools available.

5. Qualified Business Income (QBI) Deduction

Under the Tax Cuts and Jobs Act (currently in effect through 2025; Congress is expected to address its expiration), most self-employed individuals can deduct up to 20% of qualified business income. For 2025, income limits phase in at $197,300 (single) and $394,600 (married filing jointly) for specified service trades. For most freelancers below these thresholds, this deduction applies automatically.

6. Software, Subscriptions, and Tools

Any software or subscription you use for business is fully deductible: project management tools, accounting software, design apps, cloud storage, professional memberships, and industry publications. Keep receipts using TaxSort's AI scanner - photograph each receipt the moment you pay and it is automatically categorised under Software & Subscriptions.

7. Phone and Internet

Deduct the business-use percentage of your phone plan and home internet. If your phone is used 70% for business, deduct 70% of your monthly bill. Freelancers who work exclusively from home commonly deduct 50–80% of their internet bill.

8. Professional Development

Online courses, books, certifications, conferences, and workshops directly related to your current business are fully deductible. Note: costs for training in a new career are not deductible - only education that maintains or improves skills in your existing trade qualifies.

9. Business Insurance

Professional liability (E&O) insurance, general liability insurance, and business property insurance premiums are fully deductible as ordinary business expenses.

10. Meals (50% Deductible)

Business meals with clients, prospects, or business partners are 50% deductible. Document the date, attendees, business purpose, and amount. The meal must have a direct business purpose - a general networking lunch qualifies; a personal lunch where you discuss work does not.
