Worked example — Total tax: ~$27,188 | Effective rate: 30.2% | Take-home: ~$62,812
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 SE taxable = $90,000 x 0.9235 = $83,115 SE tax = ($83,115 x 0.124) + ($83,115 x 0.029) = $10,306 + $2,410 = $12,716 SE deduction = $12,716 / 2 = $6,358 AGI = $90,000 - $6,358 = $83,642 Taxable = $83,642 - $14,600 = $69,042 Federal tax = ~$11,020 State tax = $69,042 x 5% = $3,452 Total tax = $11,020 + $12,716 + $3,452 = $27,188
Result:Total tax: ~$27,188 | Effective rate: 30.2% | Take-home: ~$62,812
Example 2: LLC with High Deductions
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 SE taxable = $140,000 x 0.9235 = $129,290 SE tax = ($129,290 x 0.124) + ($129,290 x 0.029) = $16,032 + $3,749 = $19,781 SE deduction = $9,891 AGI = $140,000 - $9,891 - $6,500 - $12,000 = $111,609 Taxable = $111,609 - $29,200 = $82,409 Federal tax = ~$10,833 State tax = $82,409 x 4% = $3,296 Total = $10,833 + $19,781 + $3,296 = $33,910
Result:Total tax: ~$33,910 | Effective rate: 24.2% | Take-home: ~$106,090
Frequently Asked Questions
How are LLCs taxed by default?
By default, single-member LLCs are taxed as sole proprietorships, meaning the business income passes through to the owner personal tax return and is reported on Schedule C of Form 1040. Multi-member LLCs are taxed as partnerships by default, with income passing through to each member based on their ownership percentage and reported on Schedule K-1. In both cases, the LLC itself does not pay federal income tax at the entity level. Instead, all profits are subject to both regular income tax and self-employment tax on the owner personal return. This pass-through taxation is one of the primary advantages of the LLC structure because it avoids the double taxation that C corporations face, where profits are taxed at both the corporate level and again when distributed as dividends to shareholders.
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.
What is the Qualified Business Income deduction for LLCs?
The Qualified Business Income deduction under Section 199A of the Tax Code allows eligible LLC owners to deduct up to 20 percent of their qualified business income from their taxable income. This deduction was introduced by the Tax Cuts and Jobs Act of 2017 and is available through 2025 unless extended by Congress. For single filers with taxable income below $191,950 or joint filers below $383,900 for 2024, the full 20 percent deduction generally applies without limitation. Above those thresholds, the deduction may be limited based on W-2 wages paid by the business and the unadjusted basis of qualified property. Specified service trades or businesses including law, medicine, consulting, and financial services face additional phase-out restrictions at higher income levels. This deduction significantly reduces the effective tax rate for qualifying LLC owners.
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.
What is the difference between an LLC's legal structure and its tax classification?
An LLC is a state-law entity that provides limited liability; it is not a tax category. Federal tax treatment is a separate election, so the same LLC can be taxed as a disregarded entity, a partnership, an S corporation or a C corporation without changing its legal form. Single-member LLCs default to disregarded status reported on Schedule C, and multi-member LLCs default to partnership treatment. Changing the classification requires filing the appropriate election with the IRS.
How does a multi-member LLC report income to its members?
A multi-member LLC taxed as a partnership files an information return and issues each member a Schedule K-1 reporting their distributive share of income, deductions and credits. The LLC itself pays no federal income tax; members report their K-1 amounts on their personal returns and pay tax at their individual rates. Members are taxed on their allocated share whether or not cash was actually distributed, which is why operating agreements often include tax-distribution provisions.
Why is only 92.35 percent of net earnings subject to self-employment tax?
Employees and employers each pay half of Social Security and Medicare taxes, and the employer half is a deductible business expense. To put self-employed owners on comparable footing, the law lets them multiply net earnings by 0.9235 before applying the 15.3 percent rate, which approximates removing the employer-equivalent portion from the base. A separate above-the-line deduction for half the resulting self-employment tax then reduces adjusted gross income, though it does not reduce the self-employment tax itself.
What is a guaranteed payment and how does it differ from a distributive share?
In a multi-member LLC taxed as a partnership, a guaranteed payment compensates a member for services or for the use of capital regardless of whether the business is profitable. The LLC deducts it before computing partnership income, and the member reports it on Schedule K-1 as ordinary income generally subject to self-employment tax. A distributive share instead depends on results and follows the allocation in the operating agreement. A cash draw against an existing capital account is neither, and is not itself a taxable event.
Do LLC owners need to make quarterly estimated tax payments?
Because no employer withholds tax from LLC profits, owners generally pay federal income tax and self-employment tax through quarterly estimated payments. Underpaying triggers an interest-style penalty computed period by period, so a large fourth-quarter catch-up payment does not always cure an earlier shortfall. Safe-harbour rules based on a percentage of the current year's liability or of the prior year's tax can protect you; verify the applicable percentages with current IRS guidance or a tax professional.
