Sole prop, LLC or S-corp: the profit level where each starts making sense
Three different questions get tangled together here: liability protection, tax treatment, and administrative cost. Separating them makes the decision much simpler.
Sole proprietor — where you already are
If you are earning and have not registered anything, this is you by default. No paperwork, no fees, business income on your personal return via Schedule C.
What you do not have is liability separation — your business and personal assets are legally the same thing.
LLC — liability, not tax
An LLC is a legal structure, not a tax structure. By default a single-member LLC is taxed exactly like a sole proprietorship: same Schedule C, same self-employment tax, same return. Forming an LLC does not by itself save you a dollar in tax. This is the single most common misunderstanding in the space.
What it gives you is a liability shield between business and personal assets, and often a cleaner setup for contracts and banking. Worth having, at a modest annual cost that varies enormously by state.
The shield only holds if you treat the business as separate — a separate account, no personal spending from it. Mixing the two is how the protection gets set aside when it matters.
S-corp — the tax structure
An S-corp election is a tax treatment you can apply to an LLC or corporation. It splits your income: a reasonable salary that carries payroll tax, and distributions that do not. The saving is the self-employment tax on whatever falls on the distribution side.
What it costs: real payroll with real filings, a second tax return for the entity, bookkeeping that must be right, and state fees that range from nothing to substantial.
Two thousand to three thousand a year all-in is a realistic figure for a small operation, which is why there is a threshold below which electing loses money.
Where the break-even sits
There is no universal number, which is why anyone quoting one confidently should be treated with suspicion. It depends on your salary split and your actual admin cost. Run it with your own figures.
One thing worth knowing that most calculators get wrong: above the Social Security wage base the marginal rate drops from 15.3% to the 2.9% Medicare portion, which materially shrinks the S-corp saving for high earners. Ours accounts for it.
"Reasonable salary" is doing the work
You cannot pay yourself a token salary and take everything else as distributions. It must be defensible for the work you actually do. Setting it artificially low is among the more reliably examined things in small-business tax.
The volatility problem nobody mentions
An S-corp adds obligations that do not go away in a bad year. Payroll runs monthly whether or not the income arrived. For creator income — which can halve on a platform change or an account issue — a great year followed by a thin one leaves you running payroll for a business that is not earning.
That argues for electing later than the raw break-even suggests, and for being confident the income is durable rather than a spike.
A reasonable sequence
- Start as a sole proprietor. Separate bank account from day one regardless.
- Form an LLC when the liability exposure or the contracts warrant it.
- Consider an S-corp election when profit is comfortably and durably above your calculated break-even — and talk to an accountant before filing anything.
This is a genuinely good question to pay a professional for. The right answer is worth multiples of the fee, and the wrong one is expensive to unwind.
Primary sources
Not advice. I am not an accountant or a lawyer, and nothing here is advice from one. What I can offer is the arithmetic done carefully, the primary sources cited so you can check them, and an honest account of where the rules are genuinely uncertain. For anything you are about to sign or file, use a professional — that is what they are for.
