How to Use This Tool

Formula and Logic
The calculator first computes net income by subtracting expenses from gross income. It then applies the 15.3% self-employment tax (Social Security and Medicare) to 92.35% of net income. Federal income tax is calculated using 2023 tax brackets based on filing status, after applying the standard deduction. State tax is estimated as a flat percentage of net income. Total tax is divided by four for quarterly estimates.
Practical Notes
- Always consult a tax professional for personalized advice, especially if you have complex deductions or credits.
- Quarterly payments are due April 15, June 15, September 15, and January 15 of the following year.
- Keep detailed records of all business expenses to maximize deductions and reduce taxable income.
- Consider setting aside 25-30% of each payment for taxes to avoid underpayment penalties.

Frequently Asked Questions
What if my income varies month to month?
Use your best estimate of annual income. If income changes significantly, recalculate and adjust quarterly payments to avoid underpayment.
Can I deduct home office expenses?
Yes, if you use part of your home exclusively for business. Use the simplified method ($5 per square foot) or actual expenses, and include them in business expenses.
Do I need to pay self-employment tax on all income?
Self-employment tax applies to net earnings from self-employment. Certain income types, like some rental income, may be exempt; consult a tax advisor.
