Is an S Corp Worth It? What $120K of Profit Saves in 2026

An S corporation election lets you split your business income into two parts: a salary you pay yourself, which carries Social Security and Medicare payroll taxes, and 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 how much you must pay yourself as reasonable compensation, how much it reduces your QBI deduction, and what the extra payroll and filing costs are. For a freelancer with $120,000 of profit, my example saves about $5,125 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.

$40,000	$6,120	$42	$6,162
$60,000	$9,180	$42	$9,222

FICA is 15.3% of salary (6.2% + 1.45% each, wage base $184,500, so every salary here is under it); FUTA is $7,000 × 0.6% assuming the full state credit (Publication 15, 2026). Same function as our S corp calculator. State unemployment tax is extra.

The $60,000 row is the worked example below.

Reasonable compensation

The IRS says: “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.

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 points to 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, because 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, no other income, and takes the standard deduction. As an S corp, I 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. 1

   Sole prop: self-employment tax

   $120,000 × 92.35% × 15.3%

   $16,956
2. 2

   Sole prop: income tax

   AGI $111,522; QBI deduction $19,084; taxable income $76,338

   $11,506
3. 3

   Sole proprietor total

   $28,462
4. 4

   S corp: FICA on salary, both halves

   $60,000 × 15.3% ($4,590 employee + $4,590 employer)

   $9,180
5. 5

   S corp: FUTA

   $7,000 × 0.6% (full state credit assumed)

   $42
6. 6

   S corp: K-1 profit

   $120,000 − $60,000 salary − $4,590 employer FICA − $42 FUTA

   $55,368
7. 7

   S corp: income tax

   AGI $115,368; QBI deduction $11,074 (20% of K-1 only); taxable income $88,194

   $14,115
8. 8

   S corp total

   $9,180 + $42 + $14,115

   $23,337
9. 9

   Federal tax difference, before S corp costs

   $28,462 − $23,337

   $5,125

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 quotes for a payroll service and Form 1120-S preparation, plus your state’s entity fees and unemployment tax; what’s left is the benefit. The S corp tax savings calculator runs this same comparison with your own profit, salary and costs.

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.

• Salary matters as much as profit. At the same $120,000, raising the salary from $60,000 to $80,000 cuts the saving from $5,125 to $1,455, which costs could reduce to almost nothing.
• Low profit rarely works. At $60,000 of profit, the $1,633 difference could be mostly or entirely taken up by payroll and filing costs.

Salary	No extra costs	$2,000 of extra costs	$5,000 of extra costs
$40,000	$47,863	$61,301	$81,812
$60,000	$73,577	$93,028	$112,201

The smallest profit at which the S corp's federal tax plus its extra costs is lower than the sole proprietor's total, with the same assumptions as the worked example. The $93,028 is what our S corp calculator shows at $60,000 of salary and $2,000 of extra costs. Federal only, so state costs move it.

A higher salary raises the profit you need before the election pays off.

The election tends to make sense when profit is well above a reasonable salary for your work and your income is stable enough to run regular payroll. Run your own numbers with your reasonable compensation, state taxes and quotes before filing Form 2553, ideally with a tax professional.

How we got these figures

The FICA and FUTA rates and the wage base come from Publication 15 (2026); the election deadline from the Form 2553 instructions; the filing date for Form 1120-S from the Form 1120-S instructions; and the reasonable compensation factors and the health insurance rule from the IRS S corporation compensation page. We opened all of them on October 6, 2026. The worked example, the payroll table and the break-even table are our own arithmetic with the same functions our S corp calculator uses, rounded to the dollar. Salaries are illustrative.
