2027 figures. The IRS published the 2027 rate tables and standard deduction on November 5, 2026 (Rev. Proc. 2026-35). This calculator uses the 2026 figures, the year in force, and switches to 2027 in January.
How a single-member LLC is taxed
By default the IRS disregards a single-member LLC as separate from its owner for income tax. Its profit goes on your own return, and you pay two federal taxes on it.
- Self-employment tax: 15.3% on 92.35% of the profit, made of 12.4% for Social Security up to the wage base and 2.9% for Medicare.
- Income tax, on the profit after three deductions: half of the self-employment tax, the standard deduction, and the qualified business income (QBI) deduction of up to 20%.
Enter the net profit your tax return would show, after every deduction the business takes, including the ones a bookkeeping app may not carry, such as a home office, mileage, card processing fees and loan interest. Not gross revenue.
Examples for 2026

The 2026 federal brackets
The rate applies to each slice of taxable income, not to all of it. The 2026 standard deduction is $16,100 single, $24,150 head of household and $32,200 married filing jointly.
| Rate | Single: taxable income | Married filing jointly |
|---|---|---|
| 10% | Up to $12,400 | Up to $24,800 |
| 12% | Over $12,400 to $50,400 | Over $24,800 to $100,800 |
| 22% | Over $50,400 to $105,700 | Over $100,800 to $211,400 |
| 24% | Over $105,700 to $201,775 | Over $211,400 to $403,550 |
| 32% | Over $201,775 to $256,225 | Over $403,550 to $512,450 |
| 35% | Over $256,225 to $640,600 | Over $512,450 to $768,700 |
| 37% | Over $640,600 | Over $768,700 |
The QBI deduction at higher incomes
Below $201,750 of taxable income ($403,500 married filing jointly), the deduction is 20% of the business income, limited to 20% of taxable income. Above that it phases down for a business with no employees and no property, and is gone at $276,750 ($553,500 joint). A business in health, law, accounting, consulting or another specified service field loses it on the same range. A business with at least $1,000 of qualified income gets at least $400.
State taxes
The calculator includes each state’s own LLC taxes and fees, such as California’s annual LLC tax. State income tax is not included: it depends on your state’s own rules.
When an S election changes this
With an S election you pay yourself a salary, and only the salary carries Social Security and Medicare. Whether that saves money depends on the profit, the salary and your state.
