The S-Corp Election, Explained

An S-corp is a tax election, not a business structure. You file Form 2553 and your existing LLC or corporation gets taxed under Subchapter S, which lets you split profit between a salary (subject to payroll tax) and distributions (not subject to payroll tax). It saves real money once your profit is high enough — but less than most articles claim, because of two rules almost nobody mentions.

The two rules that shrink the savings

Only 92.35% of your profit is subject to self-employment tax. Schedule SE line 4a tells you to multiply net profit by 0.9235 before applying the 15.3% rate. So on $120,000 of net profit, the SE tax base is $110,820, not $120,000. Any article that applies 15.3% to your full profit overstates the LLC side of the comparison by roughly 8%. You also deduct one half of your SE tax above the line in computing AGI, which narrows the gap further.

Your S-corp salary is not qualified business income. The IRS specifically excludes amounts received as reasonable compensation from an S corporation from QBI. Every dollar of salary your S-corp pays you is a dollar removed from the base for the Section 199A deduction. The election preserves your eligibility for QBI, but it shrinks the deduction — and that claws back a meaningful share of the payroll tax you saved.

The honest math

Here is the self-employment tax you would pay as a sole proprietor or single-member LLC, next to the FICA you would pay on an assumed S-corp salary. Figures use the 2026 Social Security wage base of $184,500.

Two warnings about that table.

First, those salary levels are illustrative. There is no IRS safe harbor for a 50/50 or 60/40 split. Any article that shows you a savings figure without disclosing the salary it assumed is showing you an arbitrary number.

Second, the last column is a gross figure. Take the $120,000 row: the $7,775 payroll-tax saving is reduced by roughly $2,500 of lost Section 199A deduction, because $60,000 of salary drops out of QBI. Then subtract payroll processing and the cost of a separate Form 1120-S return. The realistic net benefit lands closer to $4,000 to $5,000.

At $60,000 of profit, the gross $3,888 falls to roughly $2,500 to $3,000 after the QBI effect — which may not cover the added compliance cost at all. You will see a "$40,000 to $50,000 of profit" threshold quoted everywhere. It is a practitioner rule of thumb with no statutory or IRS source, and the corrected math suggests the real breakeven sits higher.

Where the rate changes

Self-employment tax is 15.3% up to the Social Security wage base ($184,500 for 2026) and 2.9% above it — until your net SE earnings pass $200,000 (single) or $250,000 (married filing jointly). Above those thresholds the 0.9% Additional Medicare Tax applies and your marginal rate becomes 3.8%. If your profit is near $200,000, you are sitting right where the math changes character, and a generic online calculator will get it wrong.

The QBI wrinkle that cuts both ways

Below the income threshold, paying yourself a salary only hurts your QBI deduction. Above the threshold it gets more complicated:

• For most businesses, the deduction becomes limited by W-2 wages paid. In that range, paying yourself a salary can actually increase your QBI deduction rather than reduce it.
• If you run a specified service trade or business — consulting, law, accounting, health, financial services and similar — the QBI deduction phases out entirely above the threshold. That removes the clawback, but it also removes the deduction, which changes the whole calculation.

The QBI deduction was made permanent, and beginning in 2026 the phase-in range widened to $75,000 (single) and $150,000 (joint), and a new inflation-indexed minimum deduction applies to taxpayers with at least $1,000 of active QBI. The underlying income thresholds are indexed annually — check the current figure before you rely on one.

Reasonable salary is not a market-wage lookup

The IRS requires S-corp owner-employees to pay reasonable compensation for services performed before taking distributions. Underpaying yourself to shift income into distributions is a known audit target.

"What you would pay someone else to do your job" is only one of nine factors the IRS applies. The others are training and experience; duties and responsibilities; time and effort devoted to the business; dividend history; payments to non-shareholder employees; timing and manner of paying bonuses; compensation agreements; and the use of a formula to determine compensation. The IRS's stated starting point is the source of the corporation's gross receipts. If you personally generate the revenue, more of it should be salary.

That is why the "save $15,000 a year at $200,000 of profit" claim you will see elsewhere does not hold. Getting there requires a salary under roughly $80,000 on $200,000 of profit, which is exactly the pattern that draws IRS attention.

Who can own an S-corp

• Domestic entity. A U.S. corporation or LLC.
• 100 shareholders maximum. A family counts as one shareholder under IRC 1361(c)(1), which matters for family-owned businesses.
• One class of stock. Differences in voting rights do not create a second class (Treas. Reg. 1.1361-1(l)(1)), so voting and non-voting structures are permitted.
• Eligible owners. Individuals, certain trusts (grantor trusts, QSSTs, ESBTs, testamentary and voting trusts), estates, and certain exempt organizations. Partnerships and corporations cannot be shareholders.

If you are a founder without a U.S. passport

This is where the internet gets it wrong most often. The statute bars nonresident aliens, not everyone without a green card. Eligibility turns on tax residency, not immigration status.

If you are a resident alien — either because you hold a green card or because you meet the substantial presence test — you can own S-corp shares. A visa-holding founder who is physically present in the U.S. enough days to be a U.S. tax resident is eligible, even with no green card. Plenty of eligible founders talk themselves out of the election because they read "citizens or permanent residents" somewhere.

If you are genuinely a nonresident, the S-corp is off the table, and it stays off: if a nonresident alien acquires shares, the election terminates. Your realistic options are a C-corporation, or an LLC treated as a partnership or disregarded entity — the latter carrying an annual federal information-reporting obligation for foreign-owned entities.

How to actually make the election

You do not need Form 8832 first. The Form 2553 instructions state that an eligible entity meeting the requirements will be treated as a corporation as of the effective date of the S corporation election and does not need to file Form 8832. Filing 8832 first is unnecessary, and a mismatched effective date on it is a common cause of rejected or misdated elections. Form 2553 alone is sufficient.

The deadline is two months and 15 days after the start of the tax year you want the election to apply to. For a calendar-year business that is March 15 — or the next business day when March 15 falls on a weekend or holiday. You can also file at any time during the preceding tax year, which is the cleanest option if you are planning ahead. For a newly formed entity, the clock starts on the earliest of the date it first has shareholders, first acquires assets, or first begins doing business, not January 1.

If you miss it, Rev. Proc. 2013-30 provides relief for up to three years and 75 days after the intended effective date, if you have reasonable cause and the entity otherwise qualified the whole time. The form must carry the notation "FILED PURSUANT TO REV. PROC. 2013-30" at the top and include a reasonable cause statement. Do not plan around it.

What actually changes after the election

Payroll deposits are not quarterly. Federal employment tax deposits are monthly or semiweekly, based on your lookback-period liability, with a next-business-day rule once accumulated liability hits $100,000. Only the return — Form 941 — is quarterly. Some small employers are approved by the IRS to file Form 944 annually instead. Form 940 for FUTA is annual. An owner who deposits quarterly will collect failure-to-deposit penalties.

You file Form 1120-S each year and issue yourself a K-1.

Track your basis. Distributions in excess of your stock basis are taxable as capital gain. They do not simply skip tax. And losses do not flow through without limit: they are capped by stock and debt basis, then the at-risk rules, then the passive activity rules.

The entity is not always tax-free. S corporations can owe federal tax at the entity level on built-in gains (IRC 1374) and excess net passive income (IRC 1375), reported on Form 1120-S line 23c.

The Florida picture

Florida has no personal income tax, and you will see that framed as making the S-corp election more attractive here. The logic is backwards. The savings from an S-corp election are entirely federal. In states with a pass-through entity tax election, owners get an additional state-level benefit on top. Florida has no personal income tax to offset, so there is nothing extra to capture. Florida is neutral, not advantaged.

Florida does have a corporate income and franchise tax at 5.5%, imposed for the privilege of conducting business in the state. S corporations generally do not pay it, but an S-corp that owes federal income tax on line 23c of Form 1120-S must file Florida Form F-1120.

Two more Florida items once you start running payroll: you register with the Florida Department of Revenue for reemployment tax, and you still file your annual report with the Florida Department of State by May 1 each year, election or no election. And during hurricane season, deposit and filing deadlines do not pause because of a storm unless the IRS or the Florida Department of Revenue announces disaster relief covering your county.

What to do next

1. 01Get a clean profit number. Not revenue. Net profit after every legitimate deduction, for a full 12 months.
2. 02Model it with your actual salary, not a ratio. Start from the source of your gross receipts and the nine IRS factors, land on a defensible number, then run the math.
3. 03Subtract the QBI effect. Ask specifically what your Section 199A deduction looks like before and after the election, and whether your business is an SSTB.
4. 04Subtract the compliance cost. Payroll processing and a separate Form 1120-S are real, recurring costs.
5. 05Pick your effective date and file Form 2553 on time. Filing during the preceding tax year is safer than racing the March deadline. Skip Form 8832.
6. 06Set up payroll before the first pay period, not after. Confirm your deposit schedule, monthly or semiweekly, on day one.

If the numbers only work at a salary you would struggle to defend, the election is not ready yet. That is a legitimate answer, and it is cheaper than the alternative.
