A Limited Liability Company (LLC) is a state-law entity, not a federal tax classification. The IRS lets an LLC choose how it wants to be taxed, and picking the right option can meaningfully change how much self-employment tax an owner pays each year.
How the IRS Taxes an LLC by Default
Without any election, a single-member LLC is a "disregarded entity" — its income and expenses flow onto the owner's Schedule C, and net profit is subject to both income tax and self-employment (SE) tax. A multi-member LLC defaults to partnership taxation, filing Form 1065 and issuing each member a Schedule K-1. In both cases, active owners generally owe SE tax on their full share of net earnings, currently 15.3% on top of regular income tax.
The S-Corp Election Trade-Off
An LLC that qualifies can elect to be taxed as an S-corporation by filing Form 2553. Under this election, an owner who actively works in the business must be paid a "reasonable salary" through payroll, subject to Social Security and Medicare withholding. Any remaining profit can be distributed to the owner without SE tax. That split — salary versus distribution — is the entire point of the election: it can reduce the total SE tax bill, but it also adds payroll processing, quarterly payroll tax filings, and a corporate tax return (Form 1120-S).
When the Election Makes Sense
The S-corp election tends to pay off once a business generates consistent profit well above what a reasonable salary for the owner's role would cost — enough that the SE tax saved on distributions outweighs the added payroll and compliance costs. Below that point, the extra administrative burden can eat up most or all of the tax benefit. Because "reasonable salary" is fact-specific and the break-even point depends on local wage data and state rules, this is a calculation worth running with a CPA or EA rather than estimating.
A Note on C-Corp Taxation
An LLC can also elect C-corporation treatment (Form 8832), paying tax at the flat federal corporate rate. Profits distributed to owners as dividends are then taxed again at the individual level — the classic "double taxation" issue. This structure is rarely the right fit for a typical small LLC, but it can make sense for businesses reinvesting most profits, planning to raise outside investment, or pursuing specific fringe-benefit strategies. Corporate tax rates and rules change over time, so this should be evaluated with current figures, not last year's numbers.
Key Filings to Know
Regardless of structure, most LLCs need an EIN, a state annual report or franchise filing, and the federal return that matches their classification: Schedule C (single-member default), Form 1065 with K-1s (multi-member default), or Form 1120-S with K-1s (S-corp election). S-corp elections also bring payroll tax filings (Forms 941 and 940) and annual W-2s. Elections have deadlines — the S-corp election, for example, generally must be filed within two months and fifteen days of the start of the tax year it's meant to apply to, or by the end of the prior year for the following year — so timing matters as much as the decision itself.
Every LLC's right structure depends on its profit level, its owners' roles, and its state of operation. Book a free consultation with a Taxperts CPA or EA to see whether an S-corp election — or another structure — actually saves your business money.
