Independent contractors, freelancers, and gig workers typically fall under the self-employed category. This means you report your business income and expenses on Schedule C. If you also work a W-2 job, that goes on your individual return.
Explore this guide for self-employed independent contractors to see what taxes 1099 workers pay and when. We’ll go over tax forms, deductions, key deadlines, and other tax resources for individual contractors.
What is an independent contractor?
An independent contractor provides services or goods to another person or company. Under IRS common law rules, an independent contractor could be an accountant, small business owner, freelancer, or gig worker.
It treats self-employed independent contractors as sole proprietorships, which are pass-through entities. Both the independent contractor classification and your business structure determine which tax forms you pay and when.
Paying taxes as a contractor vs. employee
Independent contractors have more tax responsibilities than employees. Self-employed workers track income from different sources and may receive Form 1099-NEC, Nonemployee Compensation, from clients. Companies do not withhold Medicare, Social Security, or income taxes from contractor wages. Instead, independent contractors remit quarterly income and self-employment (SE) tax payments directly to federal and state agencies.
On the other hand, employees have taxes withheld from paychecks automatically. They receive a Form W-2, Wage and Tax Statement, from employers. Most W-2 workers can’t deduct job expenses or home offices from their taxes. But these are popular tax write-offs for independent contractors.
What taxes do independent contractors pay?
Independent contractors pay self-employment tax in addition to federal, state, and local income taxes. Some cities or counties charge gross receipts or occupational taxes, and self-employed workers in certain industries remit state sales tax. Doing business in multiple states may trigger sales tax nexus obligations.
Self-employed independent contractor taxes include the following:
- Self-employment tax: Contractors with $400 or more in net earnings (gross income minus business expenses) pay self-employment taxes, which cover Social Security and Medicare.
- Federal income tax: After deducting tax credits or deductions, independent contractors pay federal income taxes on their total income from all sources.
- State and local income taxes: Self-employed contractors may pay income taxes where they live and work (counties, cities, or states).
- Other federal taxes: Contractors may need to budget for situation-specific taxes, such as additional Medicare tax, the alternative minimum tax, or net investment income tax.
- Use, sales, and excise taxes: Some jurisdictions tax out-of-state purchases, charge excise taxes on certain services or products (like alcohol or phone services), or collect sales tax on products you sell.
Self-employed contractors who hire employees or pay themselves a salary may report and deposit employment taxes. These include the Federal Insurance Contributions Act (FICA), the Federal Unemployment Tax Act (FUTA), and the State Unemployment Tax Act (SUTA).
As a general rule, an independent contractor should set aside 25% to 30% of their net income for taxes.
How much do independent contractors pay in taxes?
The amount contractors pay in taxes varies by location, business structure, and income level. As a general rule, an independent contractor should set aside 25% to 30% of their net income for taxes. Check-in with your accountant before tax season for help calculating your independent contractor tax rate.
The self-employment tax rate is 15.3%. It applies to 92.35% of your net self-employment earnings. This rate breaks down to 2.9% on all net business profit and 12.4% on income up to $184,500 (in 2026). However, the self-employment tax deduction subtracts the employer-equivalent portion from your adjusted gross income (AGI).
An additional 0.9% Medicare tax applies to income over $250,000 (married filing jointly), $125,000 (married filing separately), and $200,000 for other taxpayers. The federal income tax brackets range from 10% to 37%. It applies to your taxable income. State income tax rates for contractors range from 0% to 13.3% and may be flat or progressive.
What tax forms do independent contractors need?
Self-employed workers file quarterly tax forms and annual returns. They may receive a 1099-NEC from clients or a 1099-K if they processed credit card payments. If you operate under a legal structure other than a sole proprietorship, the required tax forms may be different.
Independent contractor tax forms include:
- Form 1040: Most independent contractors submit an annual Form 1040, Individual Tax Return.
- Schedule C: Contractors report business income and expenses on Schedule C, Profit or Loss from Business, and attach it to Form 1040.
- Schedule SE: Independent workers with $400 or more net profit calculate their self-employment tax on Schedule SE and include it with Form 1040.
- 1099-NEC: Businesses that pay a contractor $2,000 or more (the 1099-NEC reporting threshold for the 2026 tax year) or $600 (for prior years) issue them a 1099-NEC.
- Form 1040-ES: All individuals who expect to owe at least $1,000 in federal taxes use 1040-ES to figure and pay estimated tax.
- Form W-9: Contractors return a W-9 form listing their Taxpayer Identification Number (TIN) to the person or business that pays them.
- 1099-K: Contractors, gig workers, or freelancers may get a 1099-K if clients paid them directly by credit or bank card. Payment apps and online marketplaces (eBay, PayPal, and Venmo) also send 1099-K forms based on state and federal reporting thresholds.
How your business structure impacts taxes
Most independent contractors operate as a sole proprietorship. Others form a single-member limited liability company (LLC). The IRS treats both business structures as disregarded entities, meaning they report income and expenses on a Schedule C and attach it to their personal 1040 tax return.
Other structures, including C corporations, partnerships, and S corporation status, may have different due dates, reporting requirements, or tax forms. Before forming or changing your business structure, review independent contractor tax resources or consult with a financial professional.
Key tax deadlines and filing calendar for self-employed contractors
The key tax deadlines for independent contractors include four quarterly tax payments and your annual return. If the 15th falls on a weekend or holiday, the deadline is the next business day. Generally, you pay quarterly if you expect to owe at least $1,000 for the current tax year (after deducting withholding and refundable credits).

Common tax deductions for independent contractors
Save receipts and record all business expenses independent contractors can deduct, including qualifying software, insurance, and home office costs. Look over IRS expense requirements and rate calculations to see how these apply to you, as a contractor.
Take advantage of these common tax deductions for self-employed contractors:
- Home office deduction: Use the simplified method ($5 per square foot, up to 300 square feet) or actual expenses (a percentage of home-related expenses).
- Merchant fees, bank charges, and payment processing: Deduct the cost of credit card processing and interest on business-related debts.
- Internet and phone: Subtract the business-use percentage of these bills from your independent contractor taxes.
- Qualified business income (QBI): Contractors operating as pass-through entities may qualify for the qualified business income deduction (up to 20% of qualified income).
- Vehicle expenses: Use the standard mileage rate (72.5 cents per mile from January 1 to June 30 and 76 cents per mile from July 1 to December 31) or actual expenses (add total costs and multiply by business use percentage).
- Self-employed health insurance deduction: Deduct up to 100% of qualified medical, dental, and long-term care insurance premiums for yourself, spouse, and dependents.
- Business software, supplies, and tools: Write off printer ink, sticky notes, and subscriptions for accounting, project management, and more.

- Contract labor and professional service fees: Costs related to hiring bookkeepers, subcontractors, and advisers are tax-deductible.
Throughout the year, keep a meticulous record of all your business expenses so you can minimize how much money you owe the IRS. If a business expense is both ordinary and necessary (meaning it is common, accepted, helpful, and appropriate in your trade or business), chances are you can deduct it when you prepare your taxes and save hundreds or even thousands of dollars.
How to prepare taxes as an individual contractor
Keeping information and documents organized throughout the year can save time. If you use financial software, look at the reporting options or available tax time features.
Gather tax forms, income records, and expense receipts
See IRS guidelines for what documents you might need. Since you submit your personal information at the same time, check ahead of time to see if you need more information about personal income deductions or credits.
Start by organizing the following information:
- Income forms: Find all records including 1099-NEC, 1099-K, records of income not accounted for on tax forms, and quarterly tax payment receipts. Sum up total income.
- Expenses: Sum up expenses by category, or if you use accounting software, run a profit and loss statement.
- Previous year tax return: Pull up the AGI, because you will likely need to verify this amount to file your taxes online.
- ID numbers: Your business may have an employer identification number; otherwise, use your Social Security number or individual TIN. You need ID numbers for anyone on your return.
- Personal records: Find other information you may need, like your bank account and routing numbers (to direct deposit refund or pay a tax balance).
Decide how to file taxes as an independent contractor
You can do your taxes on paper, through fillable forms (any income level), or use free or paid tax software services. The IRS provides a full list of software partners. If your AGI was $89,000 or less, you may qualify for a free federal return. You can also find information for free tax services for members of the military, veterans, and others.
Complete your annual tax return
Get everything together so you can sit down and report your self-employment income and expenses. Use Form 1040, Schedule C. Follow the prompts if using software, or review the form instructions while entering information on paper or fillable forms.
After submitting your annual return, hold onto your exact refund amount and AGI. These numbers will come in handy so you can check your refund, get tax information, and e-file next year.
Calculate estimated quarterly taxes for the upcoming year
Look at your tax form to see the current year-to-date income and expenses. The Estimated Tax Worksheet, which is part of Form 1040-ES, can help you calculate the total amount you’ll need to pay your estimated quarterly taxes. Once you know what taxes you owe, you will pay them four times each year when you submit your estimated quarterly taxes.
