Self-Employed 1099 Tax Guide for 2026
Self-Employed & 1099 Worker Taxes: What You Need to Know for 2025
This is an informational summary covering 2025 tax-year figures (returns filed in 2026), drawn from IRS sources. Figures and rules may change; confirm current details at irs.gov or with a qualified tax professional.
Self-employed and 1099 workers pay regular federal income tax on net earnings, plus a self-employment (SE) tax of 15.3% once net SE earnings reach $400 or more. Business profit and loss are reported on Schedule C, and SE tax is calculated on Schedule SE, both filed with Form 1040. Most self-employed people also make quarterly estimated tax payments throughout the year.
How much tax do self-employed people pay?
The total federal tax burden for a self-employed person consists of two layers: ordinary income tax and self-employment tax.
Income tax is assessed at standard graduated federal rates on net profit (revenue minus allowable business expenses). The rate depends on total taxable income and filing status, just as it would for an employee.
Self-employment tax is a separate 15.3% levy that covers Social Security and Medicare obligations. Employees split these contributions with their employers; self-employed individuals are responsible for the full combined amount. The threshold is low: net SE earnings of $400 or more trigger the requirement, per the IRS.
Additionally, an Additional Medicare Tax of 0.9% applies to earnings exceeding $200,000 for single filers or $250,000 for married filing jointly.
What is self-employment tax?
Self-employment tax funds the Social Security and Medicare programs. The IRS breaks the 15.3% rate into two components:
| Component | Rate | Applies to |
|---|---|---|
| Social Security | 12.4% | Net SE earnings up to $176,100 (2025 wage base set by SSA) |
| Medicare | 2.9% | All net SE earnings (no cap) |
| Additional Medicare Tax | 0.9% | Net earnings above $200,000 (single) / $250,000 (MFJ) |
The 12.4% Social Security portion applies only up to the annual Social Security wage base of $176,100 for tax year 2025, as set by the Social Security Administration. For the 2026 wage base, see ssa.gov.
Half-deduction: The IRS allows self-employed individuals to deduct one-half of their SE tax as an adjustment to gross income on Form 1040. This deduction does not eliminate the tax, but it reduces the adjusted gross income figure on which income tax is calculated. The deduction is taken on the face of Form 1040; the SE tax itself is computed on Schedule SE.
Which forms do 1099 workers file?
A self-employed person's federal return typically involves several forms in addition to Form 1040:
- Schedule C (Profit or Loss from Business): This form is where business income is reported and allowable expenses are subtracted to arrive at net profit or loss. The net profit figure flows to Form 1040 as self-employment income. See the IRS page for Schedule C.
- Schedule SE (Self-Employment Tax): This form uses the net profit from Schedule C to calculate the SE tax owed. It also calculates the deductible half of SE tax. See the IRS page for Schedule SE.
- Form 1099-NEC: Clients and platforms that paid a self-employed individual $600 or more in nonemployee compensation during 2025 are generally required to issue a Form 1099-NEC. Receiving this form does not create the tax obligation — the obligation exists regardless of whether a form was issued. The IRS notes that reporting thresholds have been subject to recent legislative change; confirm the current threshold at irs.gov. For 1099-K reporting thresholds related to payment platforms, the IRS is the authoritative source for current rules.
A qualified tax professional can help ensure the correct forms are filed and that all items are reported in the right places.
What can self-employed people deduct?
The IRS allows self-employed individuals to deduct business expenses that are ordinary and necessary — meaning common and accepted in the trade or business, and helpful and appropriate for the business. Eligibility and limits vary; a tax professional can evaluate which expenses qualify for a specific situation.
Common categories the IRS recognizes include:
| Expense Category | Notes |
|---|---|
| Home office | Portion of home used regularly and exclusively for business; calculated by square footage or simplified method |
| Business mileage / vehicle | IRS standard mileage rate or actual expenses; records required |
| Supplies and equipment | Items purchased for business use, including computers and office supplies |
| Software and subscriptions | Business-related software tools, platforms, and professional subscriptions |
| Business insurance | Premiums for liability, professional indemnity, and similar coverage |
| Professional fees | Fees paid to accountants, attorneys, and other professionals for business purposes |
| Self-employed health insurance | A portion of health, dental, and qualified long-term care premiums may be deductible as an adjustment to income |
| Retirement plan contributions | Contributions to qualified plans (SEP-IRA, SIMPLE IRA, Solo 401(k)) may be deductible; contribution limits apply |
Qualified Business Income (QBI) deduction
Eligible self-employed individuals may be able to deduct up to 20% of qualified business income under the QBI deduction established by federal tax law. Significant income limits and other restrictions apply, and not all businesses or income types qualify. The IRS provides detail on the Qualified Business Income deduction. A qualified tax professional can assess whether the deduction applies to a particular situation.
For context on whether to itemize or take the standard deduction alongside business deductions, see our guide on standard deduction vs. itemizing for 2026.
Do I need to pay quarterly estimated taxes?
Self-employed individuals generally do not have an employer withholding taxes from their pay. As a result, the IRS expects most self-employed people to pay taxes in installments throughout the year rather than in one lump sum at filing time.
The general rule: if you expect to owe $1,000 or more in federal taxes for the year after subtracting any withholding and credits, you are typically required to make quarterly estimated tax payments. Underpayment can result in a penalty.
Quarterly estimated tax payment due dates for the 2025 tax year are tied to IRS publication schedules. For a full breakdown of payment amounts, safe-harbor rules, and due dates, see our guide on quarterly estimated taxes and the IRS page on estimated taxes.

Frequently asked questions
Do I owe self-employment tax on a side gig?
Net earnings from any self-employment activity — including side gigs, freelance projects, and gig-economy platforms — are generally subject to self-employment tax once they reach $400 or more for the year, per IRS rules. This applies regardless of whether a 1099-NEC or other information return was issued.
What if I did not receive a 1099-NEC form?
Self-employment income is reportable on Schedule C whether or not a Form 1099-NEC was issued. The obligation to report income is not eliminated by a payer's failure to file or send the form. If income was received for services rendered, it generally must be reported. A qualified tax professional can help determine what is reportable.
Can I deduct my home office?
A home office deduction may be available when a dedicated portion of a home is used regularly and exclusively for business — meaning personal use of the same space disqualifies it. Both a regular method (percentage of home expenses) and a simplified method are available. Eligibility depends on specific facts; confirm with a qualified tax professional.
How do I calculate what I owe in self-employment tax?
SE tax is calculated on Schedule SE using net profit from Schedule C. The 15.3% rate applies to 92.35% of net SE earnings (a calculation that reflects the employer-equivalent portion). The resulting tax is added to income tax on Form 1040. The IRS provides the full worksheet on the Schedule SE page.
