LLC vs S-corp, plainly.

This is the question we get more than any other, from creators, contractors, agencies, and shop owners alike. The short version: an LLC is a legal structure, an S-corp is a tax election, and the election only pays off once your profit is high enough to cover the extra work it creates.

01Side by side

How the two actually differ.

What it is

LLC

A legal structure at the state level that separates you from the business.

S-corp election

A tax election you make with the IRS. Your LLC or corporation keeps its legal form and is taxed differently.

How profit is taxed

LLC

All net profit flows to your personal return and is subject to 15.3% self-employment tax.

S-corp election

You pay yourself a reasonable salary through payroll. Only the salary carries payroll tax. Remaining profit is a distribution.

Paperwork

LLC

State filing, annual report, and a Schedule C or partnership return.

S-corp election

Payroll registration, quarterly payroll filings, W-2s, and a separate 1120-S return every year.

Yearly cost to run

LLC

Usually just your state fee and bookkeeping.

S-corp election

Payroll processing, a separate business return, and tighter bookkeeping. Often $1,500 to $4,000 a year in added cost.

Best fit

LLC

New businesses, side income, and anyone with profit under roughly $60,000.

S-corp election

Consistent profit above roughly $60,000 to $80,000 where the tax savings clear the added overhead.

02The math

Where the savings start to show up.

Self-employment tax is 15.3% on your net profit. An S-corp moves part of that profit out of payroll tax. Here is roughly how it looks at different profit levels, before your specific salary, state, and deductions are factored in.

$50,000

Savings usually do not cover payroll and filing costs. Stay an LLC for now.

$80,000

Roughly break-even to modestly ahead. Worth running the numbers with an accountant.

$120,000

Typically several thousand dollars a year in self-employment tax savings.

$250,000+

Meaningful savings, plus a cleaner setup for retirement contributions and lenders.

Profit means what is left after expenses, not what lands in your account. Two businesses with the same revenue can land on opposite sides of this decision.

03Watch-outs

Mistakes we see most often.

  • Electing S-corp status and then never running payroll. That is the single fastest way to get the election challenged.
  • Paying yourself an unreasonably low salary to shrink payroll tax. The IRS looks at what someone would be paid for your role.
  • Forgetting the separate 1120-S return and its March deadline, which carries its own late penalty per owner per month.
  • Making the election based on revenue instead of profit. What matters is what is left after expenses.
  • Mixing personal and business spending, which makes the distribution versus salary split impossible to defend.
04Questions

What people ask us next.

Is an S-corp a different company than my LLC?

No. An S-corp is a tax election. Your LLC stays an LLC at the state level and simply gets taxed under Subchapter S.

When should I make the election?

Generally by March 15 for it to apply to the current tax year, though newly formed businesses have a window from their start date. Late elections can sometimes be accepted with relief.

What counts as a reasonable salary?

What a comparable employer would pay someone to do your job. Many owners land between 35% and 60% of profit, but it depends on your role, hours, and industry.

Can I undo an S-corp election?

Yes, you can revoke it, but the IRS generally will not let you re-elect for five years. It is worth getting the timing right the first time.
