Calculate how much tax you owe as a 1099 independent contractor. Estimate self-employment tax, income tax, and quarterly payments based on your 1099 income, deductions, and filing status.
The 1099 tax refers to the combined self-employment tax and income tax that independent contractors, freelancers, and gig workers must pay on their non-employee compensation. When you receive a Form 1099-NEC (Non-Employee Compensation) instead of a W-2, you are classified as an independent contractor by the IRS. This means no taxes are withheld from your payments, and you are responsible for paying both the employee and employer portions of Social Security and Medicare taxes — collectively known as self-employment (SE) tax.
The SE tax rate is 15.3% (12.4% for Social Security + 2.9% for Medicare), calculated on 92.35% of your net self-employment income. You can deduct half of your SE tax (the employer-equivalent portion) above the line on your tax return, reducing your adjusted gross income. In addition to SE tax, you also owe federal income tax on your net earnings using the standard progressive tax brackets.
✅ Did You Know? The IRS requires you to make quarterly estimated tax payments if you expect to owe $1,000 or more in taxes for the year. This calculator helps you estimate those payments so you can avoid underpayment penalties. Set aside roughly 25-30% of each 1099 payment you receive to cover your tax obligations.

Enter the total amount of non-employee compensation shown on your Form 1099-NEC. This is the gross income you received from each client before any deductions. If you have multiple 1099-NEC forms, add the amounts together.
Enter your total deductible business expenses for the year. This includes things like office supplies, software subscriptions, equipment purchases, business travel, marketing costs, professional services, and any other ordinary and necessary expenses for your trade or business. The calculator subtracts these from your gross 1099 income to determine your net self-employment income.
If you have W-2 wages from another job, interest income, or any other taxable income, enter it in the "Other Income" field. You can also optionally add a home office deduction and health insurance premiums, which further reduce your net self-employment income and taxable income.

Example: A single freelancer with $50,000 in 1099 income, $5,000 in business expenses, and no other income would have $45,000 in net self-employment income. Their SE tax would be approximately $6,352 ($45,000 × 92.35% = $41,558; × 15.3% = $6,358). They can deduct $3,179 (half) from their income. Their income tax would be calculated on approximately $26,821 ($45,000 - $3,179 - $15,000 standard deduction), resulting in income tax of about $2,970 using 2025 brackets. Total tax: ~$9,328. Quarterly payment: ~$2,332.
Where SE Base = Net SE Income × 92.35% and Additional Medicare is 0.9% on SE Base exceeding filing-status-specific thresholds ($200K single / $250K MFJ / $200K HOH).
2025 Standard Deductions: $15,000 Single, $30,000 MFJ, $22,500 HOH. Income tax is calculated using the 2025 progressive tax brackets shown above.
Where Total Gross Income = 1099 Income + Other Income. The quarterly payment is a simplified estimate (ignoring safe harbor rules).
A good rule of thumb is to transfer 25-30% of every 1099 payment you receive into a separate savings account for taxes. This covers both SE tax and income tax so you're never caught short at tax time.
The IRS requires quarterly estimated tax payments (Form 1040-ES) if you expect to owe $1,000 or more. Payments are due April 15, June 15, September 15, and January 15. Use our calculator to determine your quarterly amount.
Every legitimate business expense reduces your net income and lowers both your SE tax and income tax. Use accounting software or a dedicated business account to track expenses throughout the year — don't wait until tax season.
If you use a dedicated space in your home regularly and exclusively for business, you can deduct $5 per square foot (up to 300 sq ft) using the simplified method, or actual expenses using the regular method.
Once your net 1099 income exceeds $60,000-$80,000 annually, electing S-Corp status can reduce your SE tax. You pay yourself a reasonable salary (subject to payroll taxes) and take remaining profits as distributions (not subject to SE tax).
Contributions to a SEP IRA (up to 25% of net earnings, max $70,000 for 2025) or a Solo 401(k) reduce your taxable income while building retirement savings. This lowers both SE tax and income tax.
Self-employed individuals can deduct health, dental, and long-term care insurance premiums for themselves, their spouse, and dependents — above the line, even without itemizing.
Business software (Adobe, Microsoft 365, Slack, Zoom, project management tools), website hosting, domain names, and cloud storage are all fully deductible business expenses.
Computers, monitors, printers, office furniture, and equipment used for your business are deductible. Section 179 allows you to expense the full cost in the year of purchase up to $1,220,000 (2025).
Business mileage (70 cents/mile for 2025), parking, tolls, flights, hotels, and meals (50% deductible) for business travel are all deductible. Keep a detailed mileage log and save all receipts.
