An S corporation election lets you split your business income into two parts. There’s a salary you pay yourself, which carries Social Security and Medicare payroll taxes. And there are distributions of the remaining profit, which aren’t subject to employment taxes, per the IRS. As a sole proprietor, all of your net profit carries self-employment tax. The saving depends on three things: how much you must pay yourself as reasonable compensation, how much it reduces your QBI deduction, and what the extra payroll and filing costs run. For a freelancer with $120,000 of profit, our example saves about $5,100 in federal tax before those costs.
How the election works
An S corporation passes its income through to its shareholders, who pay tax at their individual rates, per the IRS S corporation page. To elect, an eligible entity (typically an LLC or a corporation) files Form 2553. According to the Form 2553 instructions, you must file it no more than 2 months and 15 days after the beginning of the tax year you want it to take effect, or at any time during the year before. An LLC that qualifies doesn’t need a separate Form 8832. For how the LLC side works, see LLC vs. Sole Proprietorship.
Once elected, you’re an employee of your own company:
- Salary (W-2 wages): Social Security tax of 6.2% each for employer and employee, up to the 2026 wage base of $184,500, plus Medicare tax of 1.45% each with no cap, per Publication 15 (2026). That’s 15.3% in total, the same combined rate as self-employment tax, but only on the salary.
- Federal unemployment tax (FUTA): 6.0% on the first $7,000 of wages, reduced by a credit of up to 5.4% for state unemployment taxes paid, so as little as 0.6%, per Publication 15. State unemployment tax is extra and varies by state.
- Remaining profit: reported to you on a Schedule K-1 and taxed as income, but not subject to employment taxes.
Reasonable compensation is the whole game
The IRS is direct about it: “S corporations must pay reasonable compensation to a shareholder-employee in return for services that the employee provides to the corporation before non-wage distributions may be made.” The IRS can reclassify distributions as wages, and courts have backed it.
There’s no formula or safe-harbor percentage. Factors the IRS lists include:
- training and experience,
- duties and responsibilities,
- time and effort devoted to the business,
- what comparable businesses pay for similar services,
- payments to non-shareholder employees, and
- dividend and bonus history.
The IRS also looks at where the money comes from. Income generated by your personal services points to wages. Income from employees or from capital and equipment can properly be distributions. For a solo freelancer whose income comes almost entirely from their own work, that pushes toward a substantial salary.
What else changes
- Your QBI deduction usually drops. The Form 8995 instructions say amounts received as reasonable compensation from an S corporation aren’t QBI. Only the leftover profit qualifies. See The QBI Deduction Explained.
- Retirement contributions follow your salary. Publication 560 defines plan compensation as pay for personal services, such as wages. So employer contributions to a Solo 401(k) are based on your W-2 wages, not your distributions.
- Health insurance needs to run through the company. For a more-than-2% shareholder, the IRS says premiums must be paid (or reimbursed) by the S corporation and included in your W-2 wages. You then take the self-employed health insurance deduction on your own return.
- More filings. You’ll run payroll (quarterly Form 941, annual Form 940 and a W-2), and the company files Form 1120-S. That’s due by the 15th day of the 3rd month after year-end, per the Form 1120-S instructions. Add state filings and fees, plus the cost of a payroll service and a tax preparer.
- Lower wages, lower Social Security record. Distributions don’t count as earnings subject to Social Security tax, so less of your income builds your future Social Security benefit.
- State taxes and fees. The numbers in this article are federal only. States can have their own fees and taxes for LLCs and S corporations, and a state’s treatment of an S corporation may differ from the federal one. Check your state’s tax agency and business-filing office before deciding. State costs can shrink the saving.
Worked example: $120,000 of profit
A single freelancer has $120,000 of business profit in 2026 before paying themselves, and no other income, and takes the standard deduction. As an S corp, we assume a $60,000 salary is reasonable compensation for their role. That’s an assumption for illustration: yours depends on the IRS factors above.
- 1$16,956
Sole prop: self-employment tax
$120,000 × 92.35% × 15.3%
- 2$11,506
Sole prop: income tax
AGI $111,522; QBI deduction $19,084; taxable income $76,338
- 3$28,462
Sole proprietor total
- 4$9,180
S corp: FICA on salary, both halves
$60,000 × 15.3% ($4,590 employee + $4,590 employer)
- 5$42
S corp: FUTA
$7,000 × 0.6% (full state credit assumed)
- 6$55,368
S corp: K-1 profit
$120,000 − $60,000 salary − $4,590 employer FICA − $42 FUTA
- 7$14,115
S corp: income tax
AGI $115,368; QBI deduction $11,074 (20% of K-1 only); taxable income $88,194
- 8$23,337
S corp total
$9,180 + $42 + $14,115
- 9$5,125
Federal tax difference, before S corp costs
$28,462 − $23,337
Illustrative. Single filer, 2026 standard deduction and tax rate schedule, 20% QBI deduction (below the 2026 threshold), no other income. Excludes state income and unemployment taxes, payroll service, bookkeeping, Form 1120-S preparation and state entity fees. Rounded to the dollar.
Payroll taxes fall by $7,734 ($16,956 → $9,222). But income tax rises by $2,609, mostly because the $60,000 salary no longer counts toward the QBI deduction. Net, the election saves about $5,125 a year before its extra costs. Compare that with real quotes for a payroll service and Form 1120-S preparation, plus your state’s entity fees and unemployment tax. Whatever is left is the actual benefit.
How the answer changes with profit and salary
| Profit / salary | Sole prop total | S corp total | Difference before costs |
|---|---|---|---|
| $60,000 / $40,000 | $12,037 | $10,404 | $1,633 |
| $120,000 / $60,000 | $28,462 | $23,337 | $5,125 |
| $120,000 / $80,000 | $28,462 | $27,007 | $1,455 |
| $200,000 / $90,000 | $53,430 | $43,936 | $9,494 |
$60,000 / $40,000
- Sole prop total
- $12,037
- S corp total
- $10,404
- Difference before costs
- $1,633
$120,000 / $60,000
- Sole prop total
- $28,462
- S corp total
- $23,337
- Difference before costs
- $5,125
$120,000 / $80,000
- Sole prop total
- $28,462
- S corp total
- $27,007
- Difference before costs
- $1,455
$200,000 / $90,000
- Sole prop total
- $53,430
- S corp total
- $43,936
- Difference before costs
- $9,494
Same method and assumptions as the worked example: self-employment tax vs. FICA on salary plus $42 FUTA, with 2026 income tax including the QBI deduction on each structure. Salaries are illustrative, not reasonable-compensation guidance.
Two patterns stand out:
- Salary matters as much as profit. At the same $120,000, raising the salary from $60,000 to $80,000 cuts the saving from about $5,100 to about $1,500. Once you subtract costs, that could leave almost nothing.
- Low profit rarely works. At $60,000 of profit, the $1,633 difference could be mostly or entirely eaten by payroll and filing costs.
Bottom line
An S corp election saves tax only on the profit above a reasonable salary, and it gives some of that back through a smaller QBI deduction and real administrative costs. It tends to make sense when profit is well above what a reasonable salary for your work would be, your income is stable enough to run regular payroll, and the net saving clearly beats the added cost. Run your own numbers with your actual reasonable compensation, state taxes and quotes before filing Form 2553, ideally with a tax professional.
