1099 Tax Calculator

Estimate federal taxes owed on freelance or contractor income reported on a 1099. Accounts for self-employment tax, W-2 income, business expenses, and withholdings to show your net tax liability.

About this calculator

Freelancers and independent contractors pay both the employee and employer share of FICA taxes, totaling 15.3% of net self-employment income. Net income is calculated as 1099 income minus deductible business expenses. The self-employment (SE) tax portion is: SE Tax = (form1099Income − businessExpenses) × 0.153. Income tax is then estimated by applying your marginal rate to total combined income (1099 net + W-2), minus any taxes already withheld. The formula used here applies a 22% rate for single filers and 12% for married filing jointly as a simplified bracket estimate. The two components are summed to give total estimated tax owed. Quarterly estimated payments should cover at least 90% of this amount to avoid IRS underpayment penalties.

How to use

Suppose you earned $60,000 in 1099 income, had $10,000 in business expenses, $20,000 in W-2 income, $3,000 already withheld, and file as single. Net self-employment income = $60,000 − $10,000 = $50,000. SE tax = $50,000 × 0.153 = $7,650. Combined income = $50,000 + $20,000 = $70,000. Income tax estimate = $70,000 × 0.22 − $3,000 = $12,400. Total estimated tax = $7,650 + $12,400 = $20,050. Divide by 4 to get roughly $5,013 per quarterly estimated payment.

Frequently asked questions

What is the self-employment tax rate for 1099 income in 2024?

The self-employment tax rate is 15.3% on net self-employment income up to the Social Security wage base ($168,600 in 2024). This breaks down into 12.4% for Social Security and 2.9% for Medicare. Above the wage base, only the 2.9% Medicare portion applies. You can also deduct half of the SE tax paid when calculating your adjusted gross income, which slightly reduces your overall tax bill.

How do business expenses reduce my 1099 tax liability?

Legitimate business expenses are subtracted from your gross 1099 income before any tax is calculated, reducing both your self-employment tax and income tax. Common deductible expenses include home office costs, equipment, software subscriptions, travel, and professional services. Keeping thorough receipts and records is essential, as the IRS may audit self-employed individuals. The larger your deductible expenses, the lower your net profit and therefore the lower your total tax obligation.

When should I make quarterly estimated tax payments on 1099 income?

If you expect to owe at least $1,000 in federal taxes after withholdings, the IRS requires quarterly estimated payments. The four due dates are typically April 15, June 15, September 15, and January 15 of the following year. Failing to pay enough each quarter can result in an underpayment penalty even if you pay in full at tax time. Use your estimated annual tax from this calculator divided by 4 as a baseline for each quarterly payment.
