Formula and Logic
This calculator uses 2024 U.S. federal tax brackets and Social Security Administration figures for accuracy. Key calculations include:
- Net Business Income: Gross Annual Income minus Business Deductions.
- LLC Self-Employment Tax: 15.3% on net income up to the $168,600 Social Security wage base, 2.9% Medicare on income above that, plus 0.9% additional Medicare tax for high earners.
- S-Corp FICA Tax: 15.3% on reasonable salary only (up to wage base limits), with the same Medicare surtax rules as LLCs.
- Federal Income Tax: Calculated using 2024 brackets for your selected filing status, applied to taxable income (net income minus half of self-employment/FICA tax).
- State Tax: Applied to total net business income at your entered state rate for both entity types.
Practical Notes
Keep these finance-specific considerations in mind when using this tool:
- Reasonable salary for S-Corps must align with industry standards for your role to avoid IRS penalties.
- State tax rules vary: some states charge annual LLC fees or exclude S-Corps from certain taxes, which this tool does not account for.
- Self-employment tax deductions and retirement contribution limits can further impact your taxable income.
- This tool does not account for local taxes, alternative minimum tax, or tax credits you may qualify for.

Frequently Asked Questions
What is a reasonable salary for S-Corp owners?
The IRS requires S-Corp owners to pay themselves a salary commensurate with similar roles in their industry. Use Bureau of Labor Statistics data for your job title and location to determine a defensible salary amount.
Does this tool account for state-specific LLC taxes?
No, this tool uses a flat state tax rate you enter manually. Some states charge annual franchise taxes or LLC filing fees that are not included in this calculation.
Can I use this tool for multi-member LLCs?
This tool is designed for single-member LLCs and S-Corps. Multi-member entities have additional partnership tax rules that are not reflected in these calculations.
Additional Guidance
Consult a certified public accountant (CPA) or tax attorney before making final entity structure decisions. Tax laws change annually, so verify all figures with current IRS publications. Keep detailed records of business deductions and salary payments to support your tax filings. Re-run this calculation annually as your income, deductions, and tax brackets change.
