What This Calculator Does
This calculator estimates quarterly and annual tax obligations for self-employed individuals in the United States. It accounts for self-employment tax (Social Security + Medicare), the SE tax deduction, standard deduction, and progressive federal income tax brackets.
The Formula
Self-employed workers pay both the employer and employee portions of Social Security and Medicare taxes. The 92.35% factor and the ability to deduct half of SE tax are built into the calculation. Federal income tax is then calculated on the remaining taxable income.
Step-by-Step Example
Enter gross income
Total freelance revenue before expenses. Example: $100,000.
Subtract expenses
Deductible business expenses reduce your net profit. Example: $15,000 in expenses = $85,000 net profit.
Calculate SE tax
$85,000 x 92.35% x 15.3% = $12,003 in self-employment tax.
Calculate income tax
After SE deduction ($6,001) and standard deduction ($16,100), taxable income = $62,899. Federal tax is approximately $9,100.
