At what profit does an S-corp election start to pay off?

It depends on your salary, your state's annual fees and what you pay for payroll and accounting. The mechanical break-even is often surprisingly low, but the practical answer is usually around 60,000 dollars of net profit, because below that the reasonable-salary requirement leaves very little room to reduce the 15.3 percent base.

What is a reasonable salary for an S-corp owner?

What you would have to pay someone else to do your job. The IRS can reclassify distributions as wages if the salary is obviously too low, which adds back the payroll tax plus penalties. This is the single biggest risk of the strategy.

What does an S-corp actually cost to run each year?

Typically payroll processing, a more expensive business tax return, and state-level annual fees or franchise taxes that vary widely by state. Add those up before comparing the tax saving.

Does an S-corp reduce income tax as well?

Not directly. The election targets the 15.3 percent self-employment tax base. Because wages are not qualified business income, the QBI deduction can fall, which offsets part of the saving - the calculator models this.

Structure decision

S-corp vs LLC: is the election actually worth it?

The pitch is simple - move profit out of the 15.3% base. The catch is that you have to pay yourself a defensible salary, run payroll, file another return, and pay whatever your state charges corporations. This tool subtracts all of that and tells you the net number, including when the answer is no.

Model break-even: net profit above - starts to pay off.
But do not trust that number alone: it assumes the salary can be pushed down to 40% of profit, and a reasonable salary has to survive comparison with market pay. In practice, the point where this is worth doing is usually above $60,000 of net profit.

How an S-corp actually saves money

It is not a discount. It is a change of what your profit is called.

As a sole proprietor or single-member LLC, all of your net profit is self-employment income. The 15.3% applies to 92.35% of the whole thing.
As an S-corp, you become an employee of your own company. You take a salary, which is subject to payroll tax - and the remaining profit is a distribution, which is not subject to the 15.3%.

So the saving is roughly distribution x 14.13% - minus everything it costs to run the structure.

What works against you

Payroll tax on the salary - 15.3%, both halves, still yours to pay.
Payroll processing - a real monthly cost, and a late filing is expensive.
A more complex return - 1120-S plus your 1040. Accountants charge for that.
State fees - annual reports, franchise taxes, minimum taxes. In a few states this alone eats the saving.
The QBI deduction shrinks - wages are not qualified business income, so your 20% deduction falls. This is the offset most calculators forget.

The reasonable salary problem

The whole strategy depends on your salary being defensible. Set it at 20% of profit and you have not found a loophole - you have created an audit risk, and the IRS can reclassify distributions as wages, adding tax, interest and penalties. If your profit is not comfortably above what a market salary would be, the honest answer is to wait.

When it clearly makes sense

Net profit consistently above roughly $60,000-80,000
Your work has a clear market salary you can document
Your state does not impose heavy corporate-level fees
You want the structure anyway, for retirement plan or liability reasons

When it does not

Profit below the break-even point shown above
You are in a state where the annual corporate cost is high
Your income is uneven and you would be running payroll on a salary you cannot sustain

Questions

Does an S-corp reduce my income tax too?

Not directly - the election targets the self-employment tax base. But it changes your income tax indirectly: wages reduce the QBI deduction, which usually means a slightly higher income tax bill. The calculator nets this out.

Can I elect S-corp mid-year?

Generally the election is effective at the start of the tax year and has a filing deadline (Form 2553, usually within about two months and 15 days of the start of the year you want it to apply). Check the current deadline before assuming you can still make it this year.

Do I need an S-corp, or is an LLC enough?

They answer different questions. An LLC is about liability and simplicity; an S-corp is a tax election. A single-member LLC can elect S-corp treatment - the two are not alternatives in the way the search results suggest.

What if I have employees or a partner?

Then the analysis gets more involved than this model handles - reasonable compensation rules, payroll for others, and ownership splits. Take the report to an accountant.
