Entity choice and reasonable compensation, without the hype
Sole proprietor, LLC, S corp, C corp — what actually changes, what the savings depend on, and the paperwork nobody mentions in the pitch.
September 5, 20269 min read
Entity choice is sold as a magic switch and is really a trade: some structures reduce payroll tax exposure, all of them add filings, and a few create traps if the business changes shape later. The right answer depends on profit, payroll, state, and how long you intend to hold the company.
What each structure changes
Liability protection and tax treatment are separate questions. An LLC is a legal wrapper; how it is taxed is an election. That distinction confuses more owners than any other part of this topic.
Sole proprietor: simplest filing, all net profit exposed to self-employment tax.
LLC: legal separation; taxed as a proprietorship or partnership by default.
S corp election: split between salary and distribution, with payroll obligations attached.
C corp: separate taxpayer, useful in narrow cases, with a second layer on distributions.
Reasonable compensation is the whole S corp question
The savings come from the portion of profit taken as distribution rather than salary — but the salary must be defensible for the role, the hours, and the market. Setting it too low is the single most examined position in small-business tax.
Document how the salary was determined, with comparable data, before the year starts.
Too low invites reclassification, back payroll tax, interest, and penalties.
Too low can also shrink retirement plan limits and Social Security credits.
Payroll filings, state registrations, and a separate return are the ongoing cost.
When the election is not worth it
Below a certain profit level the compliance cost eats the savings. And an election made for today's business can be awkward for tomorrow's — especially around raising outside capital or adding owners.
Run the numbers on profit after reasonable salary, not on revenue.
Add state-level fees and franchise taxes to the cost side.
Consider the exit: buyers and investors care about structure.
Revoking an election has its own waiting periods and consequences.
