S-Corp vs. LLC: When the S-Corp Election Saves You Money

An LLC and an S-Corp are not the same kind of thing, and that confusion costs business owners real money. An LLC is a legal entity. An S-Corp is a tax election that an LLC (or a corporation) can choose. The S-Corp election can save you thousands in self-employment tax once your business is profitable enough, but below a certain profit level the extra payroll and filing costs outweigh the savings. The honest answer to “should I be an S-Corp?” is: it depends on your numbers, and the math is knowable.

LLC vs. S-Corp: what is actually different

Start with the distinction that clears up most of the confusion:

• LLC is a legal structure formed at the state level. It gives you liability protection and, by default, is taxed as a sole proprietorship (single owner) or partnership (multiple owners).
• S-Corp is a federal tax election made by filing Form 2553. Your LLC keeps its legal form but changes how it is taxed.

So you are not choosing one or the other. You usually form an LLC first, then decide whether electing S-Corp tax treatment makes sense. If you have not formed yet, our business formation and entity setup service handles the structure, and our how to start a business guide walks through the full setup.

How the S-Corp actually saves tax

This is the heart of it. As a sole proprietor or default LLC, all of your net profit is subject to self-employment tax (Social Security and Medicare), currently 15.3% on the bulk of your earnings, on top of income tax.

When you elect S-Corp status, you split your profit into two buckets:

• A reasonable salary you pay yourself through payroll, which is subject to those payroll taxes.
• The remaining profit, taken as a distribution, which is not subject to self-employment tax.

That second bucket is where the savings come from. If your business nets $120,000 and a reasonable salary for your role is $70,000, only the $70,000 gets hit with payroll tax instead of the full $120,000. The savings on the difference can run into thousands of dollars a year.

The “reasonable salary” rule you cannot ignore

The IRS knows exactly why people elect S-Corp status, so it requires that your salary be reasonable for the work you do. Pay yourself too little to dodge payroll tax and you invite an audit and back taxes with penalties. Reasonable compensation is based on what someone would be paid to do your job, your role, experience, hours, and industry. Getting this number right is the single most important part of running an S-Corp correctly, and it is not a guess. Our self-employed and S-Corp tax optimization service sets this up properly.

The costs that come with the election

The S-Corp is not free. Before you elect, weigh these against the savings:

• You have to run payroll for yourself, which usually means a payroll service and quarterly filings.
• You file a separate business return (Form 1120-S) in addition to your personal return.
• Bookkeeping has to be clean, because distributions and salary must be tracked precisely.

This is why clean books matter so much for S-Corps, and why our bookkeeping guide is worth reading alongside this one.

So when does the S-Corp make sense?

As a rough rule, the S-Corp election starts to pay off once your business consistently nets somewhere in the range of $40,000 to $60,000 or more in profit beyond a reasonable salary, because that is when the self-employment tax savings clear the added payroll and filing costs. Below that, the simpler default LLC is often the better deal. But “rough rule” is not a substitute for running your actual numbers, and the election interacts with retirement contributions, the QBI deduction, and your overall plan, which is why we cover it inside year-round tax planning.

Frequently asked questions

Is an S-Corp better than an LLC?

They are not competing options. An S-Corp is a tax election an LLC can make. For a profitable business, electing S-Corp status can reduce self-employment tax. For a smaller or newer business, the default LLC taxation is usually simpler and cheaper. The right choice depends on your profit level.

How much profit do I need before an S-Corp is worth it?

A common threshold is when profit beyond a reasonable salary reaches roughly $40,000 to $60,000 or more, where self-employment tax savings outweigh the added payroll and filing costs. The exact break-even depends on your salary, state, and situation.

What salary do I have to pay myself in an S-Corp?

A reasonable salary for the work you perform, based on your role, experience, hours, and industry comparables. Paying an unreasonably low salary to avoid payroll tax is a common audit trigger.
