Self-Employment · 2026 IRS Rates
Estimate SE tax, income tax, and quarterly payments from 1099 income. Updated for 2026 brackets and $184,500 SS wage base.
This 1099 tax calculator estimates how much you owe in self-employment tax, federal income tax, and quarterly payments on your freelance earnings, using IRS Pub 505 safe-harbor rules and Schedule SE math. The 1099 tax rate combines 15.3% SE tax on 92.35% of net income plus federal income tax on your filing-status bracket. Most 1099 workers should set aside 25–30% of net income for federal taxes. See the Contractor Rate Guide for how to set a rate that covers taxes, benefits, and overhead.

| Social Security portion | 12.4% | Applied to first $184,500 of SE income |
| Medicare portion | 2.9% | No income cap |

| Standard deduction (MFJ) | $32,200 | 2026 IRS figure |

Income on Form 1099-NEC or 1099-MISC is self-employment income. Sole proprietors, LLC members, and independent contractors also qualify. All must pay SE tax in addition to income tax.
Step 1. SE Tax Base: Multiply net SE income by 92.35%. The 7.65% reduction reflects the employer's share of FICA. W-2 employees do not pay this portion out of pocket. See our FICA Tax Guide for how payroll withholding works on W-2 wages, or the How to Read a Pay Stub guide to understand each line of W-2 deductions alongside your 1099 income.
Step 2. SE Tax: SE tax = SE base × 15.3%. The 15.3% covers 12.4% Social Security (on income up to the $184,500 wage base for 2026) and 2.9% Medicare (no cap).
Step 3. SE Tax Deduction: Deduct 50% of SE tax from your gross income before calculating income tax. This is an above-the-line deduction. Itemizing is not required to claim it.
Step 4. Income Tax: Apply the standard deduction to your adjusted gross income, then calculate income tax using 2026 federal brackets.
Step 5. Quarterly Payments: Divide total estimated tax by 4 and pay by each quarterly due date. Use the Quarterly Tax Calculator for safe harbor analysis.
For a full breakdown of how self-employment tax works, including the SE deduction and quarterly planning, see our Self-Employment Tax Guide. To see the Schedule SE calculation in isolation, use the Self Employment Tax Calculator. To compare 1099 vs W-2 tax burden at the same gross income, use the W-2 vs 1099 Tax Calculator.
If you also receive W-2 income from a tipped occupation, you may qualify for the No Tax on Tips deduction under IRC § 224. Use our No Tax on Tips Calculator to estimate that deduction. If you earn W-2 overtime pay, the No Tax on Overtime deduction under IRC § 225 may also apply. Use our No Tax on Overtime Calculator to estimate it.
If you itemize on Schedule A and your combined state income taxes and property taxes exceed $10,000, the OBBBA SALT cap increase may provide significant additional savings. The cap rose to $40,000 for TY 2025–2029. Use our SALT Deduction Calculator to estimate your incremental benefit, particularly if you are in a high-tax state such as California, New York, or New Jersey.
If you financed a new U.S.-assembled vehicle purchased after December 31, 2024, you may also qualify for the OBBBA qualified motor vehicle loan interest deduction: up to $10,000 per year for TY 2025–2028, subject to eligibility, filing-status, and income-limit rules. Use the Auto Loan Interest Calculator to estimate that deduction alongside your 1099 income picture.
For a complete side-by-side summary of all six OBBBA provisions, including eligibility, phase-outs, and stacking rules, see the OBBBA Tax Changes Guide.
A single freelance graphic designer reports $85,000 in net 1099 income after business expenses. No W-2 income. Standard deduction applies.
This estimate does not include state taxes, Additional Medicare Tax, retirement deductions, or other credits. Use the calculator above for a personalized figure.
At LMN Tax Inc., the most common 1099 filing error is clients who omit self-employment tax from their planning entirely. Many assume their tax liability mirrors a W-2 employee's rate. It does not. A freelancer with $80,000 in net income typically owes more than $11,000 in SE tax before income tax is calculated. Planning for both obligations in the first quarter prevents the large April balance that leads most first-year self-employed clients to us.
The quarterly safe harbor rule is often overlooked. Paying 100% of the prior year's tax liability in four equal installments eliminates the underpayment penalty regardless of what you actually owe in the current year. For clients whose income fluctuates significantly, this is more reliable than trying to estimate the current year precisely each quarter.
If your net SE income consistently exceeds $50,000 per year, the S-corp election deserves a formal analysis. The strategy splits income between a reasonable salary (subject to FICA) and distributions (not subject to SE tax). The payroll administration cost must be weighed against the SE tax savings. This calculator models the 1099 side only. Use the LLC vs S-Corp Calculator to model both structures side by side before making that decision.
Use the quarterly payment figure to set up four equal IRS estimated tax payments using Form 1040-ES. Payment due dates for 2026: April 15 (Q1), June 15 (Q2), September 15 (Q3), January 15, 2027 (Q4).
If your income varies significantly month to month, recalculate after each quarter and adjust the remaining payments. You do not have to pay equal amounts each quarter: you can annualize income and adjust, though the equal-payment safe harbor method is simpler for most filers.
The total tax figure from this calculator is a planning estimate. Your actual tax return will reflect Schedule C net income, Schedule SE, applicable credits, and any additional deductions. If total federal tax exceeds $1,000 and you have no withholding elsewhere, start quarterly payments immediately to avoid penalties. If you are already behind on quarterly payments for the current year, use our Form 2210 penalty calculator to estimate the IRC §6654 underpayment penalty you may owe at filing.
If you also received a scholarship, fellowship, or graduate stipend, use the Scholarship Tax Calculator to determine the taxable portion under IRC §117 before combining it with your 1099 income for a complete picture of your estimated tax.
If your 1099 income is low this year, check whether you even need to file. The Do I Need to File Taxes? Calculator applies the 2025 IRS thresholds from Publication 501 and includes the self-employment income trigger ($400 net SE earnings) that applies regardless of gross income.
If you also receive W-2 wages with bonuses or RSU equity compensation alongside your 1099 work, the W-2 side has its own under-withholding pattern: the 22 percent supplemental rate often misses your true marginal bracket once 1099 income is layered on. Run the Bonus Tax Calculator for cash bonuses and the RSU Tax Calculator for equity vests to see the combined picture.
