When should my LLC elect S-Corp status?

There is no profit number in the tax code that triggers an S-Corp election. The election pays when the payroll tax it saves is larger than what it costs to run.

For 2026, the savings is roughly 15.3% of the profit you take as distributions instead of salary. The cost is payroll, a separate corporate tax return and state filings. With a salary you can defend plugged in, the answer is usually clear.

Who this applies to

• Single-member LLC owners whose business income comes from their own work: consultants, agents, contractors, coaches, designers and other service businesses. A sole proprietor without an entity has to form an LLC or corporation before electing.
• Multi-member LLC owners weighing the same election, as long as every owner is an eligible shareholder, such as a U.S. citizen or resident individual.
• 1099 earners with steady profit who are paying self-employment tax on all of it.

Who it doesn't

• Businesses with little or no profit. With nothing left after a reasonable salary, there is nothing to save.
• LLCs that hold long-term rental property. Rents from real estate are generally excluded from self-employment income under IRC section 1402(a)(1), so there is little self-employment tax for an S-Corp to save. Rentals received as a real estate dealer are the exception.
• Companies that can't meet the S-Corp rules: more than 100 shareholders, an owner that is a partnership, a corporation or a nonresident alien, or more than one class of stock (for example, investors who want preferred returns).

How does an S-Corp save tax in the first place?

As a sole proprietor or single-member LLC, your profit is subject to self-employment tax. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. It applies to 92.35% of your net profit, because the Code lets you subtract the employer-equivalent half of the rate before computing it.

For 2026, the 12.4% Social Security piece stops at $184,500 of combined wages and self-employment earnings. The 2.9% Medicare piece has no cap. An extra 0.9% Additional Medicare Tax applies above $200,000 for single, head of household and qualifying surviving spouse filers, $250,000 for married couples filing jointly and $125,000 for married filing separately.

An S-Corp splits the same profit into two buckets. Your salary goes through payroll and pays the same 15.3%, half from the company and half from your paycheck. What is left over can come out as a distribution, which carries no Social Security or Medicare tax.

What salary do you have to pay yourself?

A reasonable one. The IRS says an S-Corp must pay reasonable compensation to a shareholder who works in the business before taking non-wage distributions, and it can reclassify distributions as wages if the salary is too low.

The IRS lists factors it looks at, including your training and experience, your duties, the time you put in, and what comparable businesses pay for similar services. There is no fixed percentage. The "60/40 split" you see online is not IRS guidance.

This is why profit alone can't answer the question. A consultant whose market salary is $70,000 has far more room than one whose work would command $140,000. The full method is in how reasonable salary is set for an S-Corp owner.

What does an S-Corp cost to run?

The election itself is a short form, Form 2553. The costs come every year after:

• Payroll. You become an employee of your own company. That means a payroll service or software, quarterly payroll filings and a W-2 each year.
• Federal unemployment tax. FUTA for 2026 is 6.0% on the first $7,000 of each employee's wages, or 0.6% ($42) after the maximum 5.4% credit, which requires paying state unemployment tax in full and on time. Employers in a credit reduction state pay more, and so can employers in states that exclude corporate officer wages from state unemployment tax. State unemployment tax itself is a separate cost that varies by state.
• A second tax return. The S-Corp files Form 1120-S, due by the 15th day of the third month after year end (March 15 for a calendar year, moved to the next business day when it falls on a weekend or legal holiday). For 2025 returns filed in 2026, the late penalty with no tax due is $255 per shareholder for each month or part of a month it is late, up to 12 months.
• State filings. In Georgia, an S-Corp files Form 600S. Georgia's Department of Revenue says corporations with net worth of $100,000 or less owe no net worth tax but still have to file; the maximum is $5,000 for net worth over $22 million.
• Bookkeeping discipline. Separate accounts, an accountable plan for reimbursing home office and mileage, and basis tracking for your distributions.

What that adds up to depends on the provider and the state. Real quotes belong in the math, not guesses.

Where does the break-even land?

Below the Social Security wage base, the payroll tax saved is roughly:

15.3% × (92.35% × profit − salary)

Subtract the added costs, and the result is your rough net savings. If it's negative or close to zero, the election isn't worth the overhead.

Two patterns show up quickly. First, the higher the salary relative to profit, the thinner the savings, no matter how large the profit is.

Second, above the 2026 wage base of $184,500, a sole proprietor already pays only the 2.9% Medicare portion (plus 0.9% Additional Medicare Tax above the threshold) on the excess. Savings on that slice are much smaller than on profit below the base.

A worked example

What about income tax and the QBI deduction?

The election doesn't lower your income tax rate. It shuffles deductions, and the shuffle can work against you.

As a sole proprietor, you deduct the employer-equivalent half of your self-employment tax. As an S-Corp, the company deducts its half of payroll tax instead. On a smaller salary, that deduction is smaller, so taxable income can tick up slightly.

The bigger item is the qualified business income (QBI) deduction under section 199A, generally up to 20% of qualified business income. Under section 199A(c)(4), reasonable compensation the S-Corp pays you is not QBI. Every dollar moved into salary is a dollar out of the QBI base, which can cost up to 20 cents of deduction.

Above the 2026 threshold of $201,750 of taxable income ($403,500 married filing jointly), the deduction is also limited by W-2 wages paid, and the limit is fully in effect at $276,750 ($553,500 joint). For a business that isn't a specified service trade or business, a higher salary can actually help there. For a specified service business, such as consulting, health, law or financial services, the deduction phases out completely above the range.

The details are in how S-Corp salary affects the QBI deduction.

How it changes for an S-Corp owner

The day the election takes effect, your business stops being a Schedule C line. You become an employee of your own company, with a salary, withholding and a W-2.

That shift changes more than payroll tax. Mileage and home office move to company reimbursements, health insurance premiums go on your W-2, and retirement contributions are figured on your salary rather than your net profit. Each one needs setting up; the checklist is in what to set up after the S-Corp election.

Timing matters too. A calendar-year LLC can file Form 2553 any time in 2026 for a January 1, 2027 start, or by March 15, 2027. An LLC that files a valid Form 2553 doesn't need a separate Form 8832. See year-end moves and the 2027 election deadline.

The bottom line

There is no magic profit level. The S-Corp election pays when roughly 15.3% of the gap between profit and a defensible salary is larger than the cost of running payroll and a second return.

For many service businesses, that starts to happen once profit sits comfortably above what the owner's work would earn as a salary. For others, a high market salary or thin margins mean it never does.
