Electing S Corporation Status for an LLC: When the Numbers Work
An S corp election lets an LLC owner take a reasonable salary and receive remaining profit without self-employment tax, in exchange for added costs.
Electing S Corporation Status for an LLC: When the Numbers Work
1 / 7
What does electing S corp status actually change?
- An LLC can file Form 2553 to be taxed as an S corporation without changing its legal form under state law.
- Owners who work in the business become employees and must receive a reasonable W-2 salary, subject to payroll taxes.
- Profit above that salary passes through to owners' returns and is not subject to Social Security or Medicare tax.
- Income tax on the business's profit generally stays about the same; the savings come mainly from payroll-type taxes.

What does electing S corp status actually change?
- An LLC can file Form 2553 to be taxed as an S corporation without changing its legal form under state law.
- Owners who work in the business become employees and must receive a reasonable W-2 salary, subject to payroll taxes.
- Profit above that salary passes through to owners' returns and is not subject to Social Security or Medicare tax.
- Income tax on the business's profit generally stays about the same; the savings come mainly from payroll-type taxes.
Where do the savings come from?
- A single-member or partnership LLC owner pays self-employment tax of 15.3% on 92.35% of net earnings, up to the Social Security wage base.
- The 2026 wage base is $184,500; above it, only the 2.9% Medicare portion applies, plus 0.9% above $200,000 single or $250,000 joint.
- Illustration: on $200,000 of 2026 profit, self-employment tax is about $28,200; with a $110,000 salary, payroll tax is about $16,800.
- That roughly $11,400 difference is before payroll costs, state taxes, and income-tax effects, which can shrink it considerably.
- Savings per dollar are largest on profit below the wage base; above it, the rate difference drops to Medicare's 2.9%.
What counts as a reasonable salary?
- The IRS expects pay comparable to what the business would pay someone else to perform the same services.
- Factors include training and experience, duties, time devoted, pay at comparable businesses, and the company's gross receipts.
- Paying too little invites the IRS to recharacterize distributions as wages, with back taxes, interest, and penalties.
- Writing down how the salary was set, using market data for the role and location, helps support it later.
Ongoing costs and eligibility limits
- Payroll must run on a schedule, with deposits and filings such as Forms 941, 940, and W-2, usually through a payroll provider.
- The business files Form 1120-S and issues Schedule K-1s, which often means higher accounting fees.
- Some states add cost; California charges S corporations 1.5% of net income with an $800 minimum franchise tax.
- Eligibility limits apply: generally no more than 100 shareholders, one class of stock, and no nonresident alien or entity owners.
How and when is the election made?
- Form 2553 is due within two months and 15 days after the start of the tax year it takes effect, which is March 15 for calendar-year businesses.
- It can also be filed any time during the prior year, and every shareholder must consent.
- Late elections can often be fixed under Revenue Procedure 2013-30 within three years and 75 days, if there was reasonable cause.
- Revoking S status generally bars re-electing it for five years, so the decision is harder to undo than it looks.
Side effects of switching
- Your 20% qualified business income deduction, made permanent in 2025, is calculated on profit after salary, so it may shrink.
- Solo 401(k) employer contributions are based on W-2 salary, so a lower salary means less retirement contribution room than before.
- Social Security benefits are based on wages, so a lower salary can mean lower future benefits.
- Health insurance for owners above 2% is reported in W-2 wages, then generally deducted on the owner's return.
Key takeaways
- An S corp election can reduce payroll-type taxes when profit consistently exceeds a defensible salary.
- Net savings depend on the salary, the wage base, state taxes, QBI effects, and the cost of payroll and extra filings.
- The election has a firm deadline and a five-year re-election bar if revoked.
- This is educational only; Rubric does not prepare tax returns, so model the switch with a CPA before filing.
