*This calculator provides a simplified estimate of federal tax on self-employment income only. It does not calculate state or local taxes, tax credits, estimated payments, withholding, or penalties, and it does not model S corporation, C corporation, or partnership returns. It also does not account for self-employed health insurance, retirement contributions such as a SEP-IRA, or the rule that both spouses must itemize if one does when filing separately. Your actual tax may differ based on your full tax situation. This estimate is not tax advice. Book a discovery meeting with Toran Accounting to learn more.

Estimated Tax Liability and Income Flow
Upon generating your tax report, the calculator provides a clear overview of your estimated tax liability and an income & deduction flow:
Estimated Tax Liability
- Effective Rate: The tax your 1099 income adds, as a share of your business profit.
- Self-Emp: Estimated self-employment tax (Social Security and Medicare).
- Federal: Estimated federal income tax.
- Net Profit: Your business profit after expenses.
- After Tax: Your estimated income remaining after federal income tax, self-employment tax, and payroll taxes on W-2 wages. It does not reflect state taxes.
Income & Deduction Flow
- Total Gross Income: Sum of all income sources.
- 1099 Business Income: Income from your LLC.
- W-2 Wages: Any W-2 income.
- Business Expenses: Deductible business costs.
- Deductible Half of SE Tax: The portion of self-employment tax that is deductible.

Note: This calculator is designed for default-taxed pass-through LLC income. Members of a multi-member LLC (taxed as a partnership) can use it with their share of the LLC's profit from their Schedule K-1. It does not prepare the partnership return (Form 1065), and S-Corp elections, C-Corp elections, franchise fees, and local taxes are not modeled here. State taxes are not calculated.
What is an LLC
What is an LLC and How is it Taxed?
A Limited Liability Company (LLC) is a business structure that combines the pass-through taxation of a partnership or sole proprietorship with the limited liability of a corporation. This means that the owners (members) are generally not personally responsible for the company’s debts or liabilities.
For tax purposes, an LLC is highly flexible. By default, a single-member LLC is taxed as a sole proprietorship, and a multi-member LLC is taxed as a partnership. In both cases, the business income “passes through” to the owners, who report it on their personal tax returns (Form 1040, Schedule C for single-member LLCs; Form 1065 for multi-member LLCs). This avoids the “double taxation” that C-Corporations face.
However, an LLC can also elect to be taxed as an S-Corporation or a C-Corporation by filing the appropriate forms with the IRS. This flexibility allows business owners to choose the tax treatment that best suits their financial situation and goals.
Key Tax Components for LLCs
- Self-Employment Tax (SE Tax): If your LLC is taxed as a sole proprietorship or partnership, you are generally considered self-employed and must pay self-employment taxes (Social Security and Medicare) on your net earnings from self-employment. This is a significant consideration for LLC owners.
- Federal Income Tax: Your LLC's profits (after deductions) are reported on your personal income tax return and are subject to federal income tax rates.
- State and Local Taxes: State income tax rules vary widely. Some states have no income tax, while others have progressive rates. Additionally, some states and localities may impose franchise taxes, gross receipts taxes, or other business-specific taxes on LLCs.
- Qualified Business Income (QBI) Deduction: Eligible self-employed individuals and small business owners may be able to deduct up to 20% of their qualified business income, subject to certain limitations.
Common Queries
Frequently Asked Questions
Do all LLCs pay self-employment tax?
Generally, yes. If your LLC is taxed as a sole proprietorship or partnership, you will typically owe self-employment tax on your share of net earnings once they reach $400 or more for the year. Some LLC members who are not active in the business may qualify for an exception, but those rules are complex. If your LLC elects to be taxed as an S corporation, you pay yourself a reasonable salary subject to payroll taxes, and remaining distributions are generally not subject to self-employment tax.
How does an LLC reduce my personal liability?
An LLC generally protects your personal assets, like your home and savings, from business debts and lawsuits. That protection has limits. It typically does not cover debts you personally guarantee, claims arising from your own negligence or professional services, or situations where personal and business funds are mixed. Keeping separate business accounts and records helps preserve this protection. For questions about your specific situation, we recommend consulting an attorney.
Can an LLC choose how it's taxed?
Yes. By default, a single-member LLC is taxed as a sole proprietorship and a multi-member LLC is taxed as a partnership. An LLC can instead elect to be taxed as a C corporation or, if it meets the eligibility requirements, as an S corporation. The right choice depends on your profit, goals, and long-term plans.
What are common deductions for an LLC?
Common deductible business expenses include office rent, utilities, supplies, software, marketing, professional fees (legal and accounting), and the business-use portion of vehicle expenses. Self-employed health insurance premiums and retirement contributions, such as a SEP-IRA or Solo 401(k), may also be deductible, but they are claimed on your personal return rather than as business expenses. Do not include them in the business expenses field in the calculator above.
When are LLC taxes due?
Most LLC owners need to make quarterly estimated tax payments during the year, typically due April 15, June 15, September 15, and January 15 of the following year. Annual filing deadlines depend on how your LLC is taxed. A single-member LLC reports its income on the owner’s personal return (Form 1040), generally due April 15. A multi-member LLC files a partnership return (Form 1065), generally due March 15, and each member reports their share on their personal return. When a due date falls on a weekend or holiday, it moves to the next business day.
When should my LLC consider an S corporation election?
An S corporation election can reduce self-employment tax once your business is consistently profitable. As an S corporation owner, you pay yourself a reasonable salary subject to payroll taxes, and the remaining profit you take as distributions is generally not subject to self-employment tax. The election also adds costs, including payroll, a separate business tax return, and stricter recordkeeping, so the savings need to outweigh them. Whether it makes sense depends on your profit, what counts as reasonable pay in your field, and your state’s rules. Contact Toran Accounting to find out whether an S corporation election could save you money.
