This question usually shows up right when a cleaning business is actually taking off -- adding commercial contracts, bigger buildings, real revenue -- which is exactly when it's worth answering correctly.
This is the part that trips up most owners first: LLC and S corp aren't two competing business structures you pick between. An LLC is a legal entity. S corp is a *tax election* you can apply on top of an LLC (or a corporation) -- it doesn't change your liability protection, your contracts, or how clients see your business at all. If you already formed an LLC, the real question isn't "LLC or S corp" -- it's "should my existing LLC elect to be taxed as an S corp."
By default, a single-member LLC is a "disregarded entity" -- all of its net profit flows to your personal return and is subject to self-employment tax (Social Security + Medicare, currently 15.3%) on top of regular income tax. It's simple: no payroll, no extra filings, just your profit taxed as self-employment income.
Once you elect S-corp tax treatment, you become a W-2 employee of your own business. You run payroll, pay yourself a salary, and only that salary is subject to employment tax -- the remaining profit gets paid out as a distribution, which isn't subject to self-employment tax at all. That gap is the entire reason owners consider it: real, legal tax savings, but only once the math actually works in your favor.
There's no universal cutoff, but a commonly cited rule of thumb is that S-corp election starts paying for itself somewhere in the $40,000–$60,000+ net profit per year range, after a reasonable salary is factored in. Below that, the added cost of payroll administration and a separate business tax return often eats up most or all of the self-employment tax savings -- making the switch a wash or even a net loss for a smaller operation.
This is the part owners most often get wrong, and it's a real audit flag: the IRS requires you to pay yourself a "reasonable salary" for the work you actually do, based on what a similar role would pay in your market, *before* taking any distributions. Paying yourself a token salary and taking the rest as distributions specifically to dodge employment tax is the exact pattern the IRS looks for -- the savings only hold up if the salary number is defensible.
This is usually the actual trigger for the question, not a coincidence. A cleaning business that's purely residential, one home at a time, often sits well under the threshold where S-corp status pays off. The moment you start bidding commercial contracts or taking on bigger buildings, net profit can climb past that breakeven point fairly quickly -- which is exactly when it's worth re-running the numbers, not before.
Budget for a payroll service (to run your own salary correctly), a separate business tax return (Form 1120-S) on top of your personal filing, and cleaner books than a sole-owner LLC typically needs -- which is also exactly why keeping business and personal finances separated stops being optional once you're here. These are real, recurring costs that have to be weighed against the self-employment tax savings, not just the savings number in isolation.
This is one of the few decisions in this business genuinely worth paying a CPA for a specific answer rather than guessing from a rule of thumb -- bring them your actual current net profit and a realistic growth projection, and let them run the real comparison for your numbers. See the general LLC vs. sole proprietorship breakdown if you haven't settled that first step yet, and quarterly estimated taxes and deductions for what else tends to catch owners off guard around this same part of running the business.
