Llc Tax Calculator
Estimate taxes for an LLC based on income, filing status, self-employment tax, and deductions. Enter values for instant results with step-by-step formulas.
Formula
Total Tax = Federal Income Tax + Self-Employment Tax (15.3%) + State Tax
Where Federal Income Tax uses progressive brackets on taxable income (AGI minus deductions), Self-Employment Tax is 15.3% of 92.35% of net earnings (12.4% Social Security + 2.9% Medicare), and State Tax is applied at the state rate on taxable income.
Worked Examples
Example 1: Single-Member LLC Freelancer
Problem: Gross income $120,000, business expenses $30,000, single filer, standard deduction $14,600, no retirement contributions, 5% state tax.
Solution: Net business income = $120,000 - $30,000 = $90,000\nSE taxable = $90,000 x 0.9235 = $83,115\nSE tax = ($83,115 x 0.124) + ($83,115 x 0.029) = $10,306 + $2,410 = $12,716\nSE deduction = $12,716 / 2 = $6,358\nAGI = $90,000 - $6,358 = $83,642\nTaxable = $83,642 - $14,600 = $69,042\nFederal tax = ~$11,020\nState tax = $69,042 x 5% = $3,452\nTotal tax = $11,020 + $12,716 + $3,452 = $27,188
Result: Total tax: ~$27,188 | Effective rate: 30.2% | Take-home: ~$62,812

Problem: Gross income $200,000, expenses $60,000, married filing jointly, standard deduction $29,200, $6,500 retirement, $12,000 health insurance, 4% state tax.
Solution: Net income = $200,000 - $60,000 = $140,000\nSE taxable = $140,000 x 0.9235 = $129,290\nSE tax = ($129,290 x 0.124) + ($129,290 x 0.029) = $16,032 + $3,749 = $19,781\nSE deduction = $9,891\nAGI = $140,000 - $9,891 - $6,500 - $12,000 = $111,609\nTaxable = $111,609 - $29,200 = $82,409\nFederal tax = ~$10,833\nState tax = $82,409 x 4% = $3,296\nTotal = $10,833 + $19,781 + $3,296 = $33,910
Result: Total tax: ~$33,910 | Effective rate: 24.2% | Take-home: ~$106,090
Frequently Asked Questions
What is self-employment tax and how much is it?
Self-employment tax is the Social Security and Medicare tax that self-employed individuals must pay, equivalent to both the employer and employee portions of FICA taxes. The total self-employment tax rate is 15.3 percent, consisting of 12.4 percent for Social Security on earnings up to the annual wage base ($168,600 for 2024) and 2.9 percent for Medicare on all earnings with no cap. An additional 0.9 percent Medicare surtax applies to earnings above $200,000 for single filers or $250,000 for married filing jointly. The tax is calculated on 92.35 percent of net self-employment earnings rather than the full amount. Importantly, half of the self-employment tax is deductible as an adjustment to income on your personal return, which reduces your adjusted gross income and therefore your income tax liability.
Should an LLC elect S-Corp taxation to save on taxes?
Electing S-Corp taxation can save LLC owners money on self-employment taxes by allowing them to split income between a reasonable salary subject to FICA taxes and distributions that are not subject to self-employment tax. This strategy typically becomes beneficial when net business income exceeds $50,000 to $60,000 annually. For example, an LLC earning $120,000 net income would pay about $17,000 in self-employment tax. As an S-Corp paying the owner a $70,000 salary, only the salary is subject to FICA taxes of about $10,700, saving roughly $6,300 annually. However, S-Corp election adds costs including mandatory payroll processing, additional tax returns, reasonable compensation requirements, and potential state-level taxes. The breakeven point depends on your specific income level, state tax laws, and the cost of additional compliance requirements that S-Corp status requires.
What business expenses can an LLC deduct?
LLCs can deduct all ordinary and necessary business expenses from their gross income before calculating taxes. Common deductible expenses include office rent or a home office deduction calculated from the percentage of home used exclusively for business, business-related vehicle mileage at the IRS standard rate of 67 cents per mile for 2024, health insurance premiums for self-employed individuals which are deductible above the line, retirement plan contributions to SEP-IRA, SIMPLE IRA, or Solo 401k plans, professional services like accounting and legal fees, business insurance premiums, office supplies and equipment, marketing and advertising costs, and continuing education related to your business. Cell phone and internet costs can be partially deducted based on business use percentage. Meals with clients are 50 percent deductible. Properly tracking and maximizing these deductions is essential for reducing your overall tax liability as an LLC owner.
