"Should I be an LLC or an S-corp?" is one of the most common questions we hear, and it contains a hidden error. They are not competing entity types. An LLC is a legal structure created under state law. An S-corp is a federal tax election. An LLC can elect to be taxed as an S-corp.
Two separate decisions
Legal structure determines liability protection, ownership, and governance. For most small businesses the LLC wins on flexibility and simplicity.
Tax treatment determines how profits are taxed. A single-member LLC is taxed by default as a sole proprietorship; a multi-member LLC as a partnership. Either can elect corporate or S-corp treatment.
So the real question is usually: should my LLC make an S election?
What the S election changes
Under default treatment, an active owner's share of profit is generally subject to self-employment tax. Under an S election, the owner must be paid reasonable compensation as W-2 wages subject to employment taxes; remaining profit may be distributed without self-employment tax.
That difference is where the savings come from, and it only becomes meaningful once profit comfortably exceeds a reasonable salary for the work performed.
What it costs
- Running payroll, with filings and deposits
- A separate business tax return
- Higher bookkeeping and accounting fees
- Ownership restrictions, limits on number and type of shareholders, and a single class of stock
- Real exposure if "reasonable compensation" is set unreasonably low
Paying yourself an implausibly small salary to shrink employment taxes is a well-known audit issue, not a clever strategy.
A practical way to think about it
If the business is new, unprofitable, or profitable only modestly, the added cost and complexity usually outweigh the benefit. As consistent profit grows well beyond a market salary for your role, the election becomes worth modelling with your CPA.
You are also not locked in. Many businesses start as a straightforward LLC and elect S treatment later when the numbers justify it.
Get the structure right first
Tax elections sit on top of a legal foundation. Get the LLC formed correctly, with a proper operating agreement, and the tax question becomes far easier to answer later. See our flat-fee LLC formation, and talk to a tax professional about the election itself.
