Morkel Financial ran the full comparison for a one-person service business with $120,000 of profit in 2026, and the result should cool down anyone who thinks the S-corp election is free money. As a sole proprietor: $16,955 in self-employment tax plus $11,506 in federal income tax, $28,461 total. As an S-corp with a $70,000 salary: $10,710 in payroll tax plus $14,428 in income tax, $25,138 total. The election saves $3,323. Then you pay $1,500 to $3,000 for payroll processing and a second tax return, and what is actually left is $323 to $1,823. That is the honest version of S-corp vs sole proprietor self-employment tax savings, and it is the version you should decide on.
Why the savings exist at all
The mechanics are simple. A sole proprietor pays 15.3% self-employment tax on 92.35% of every dollar of net profit. An S-corp owner pays payroll tax only on the W-2 salary; distributions are exempt from Social Security and Medicare tax. The gap between those two treatments is the entire prize. On $120,000 of profit, the sole proprietor's SE tax is $16,955. The S-corp's payroll tax on a $70,000 salary is $10,710. The $6,245 difference is real, though income tax effects and the QBI deduction shave it to the $3,323 net figure above.
Now the part people skip: you do not get to pick the salary. Rev. Rul. 74-44 is still the backbone of every reasonable compensation exam, and Watson v. United States showed what happens when owners treat the salary as a dial: the court reset a $24,000 salary to $91,044. If your profit is roughly what your labor is worth, there is no room between salary and profit, and no election to make. The savings live in the gap between what you earn and what the work costs, and the IRS gets to argue about where that gap starts.
The break-even table
| Net profit | Verdict | Why |
|---|---|---|
| Under $50,000 | Almost never worth it | Compliance costs of $2,500 to $5,000 eat most or all of the FICA savings |
| $60,000 - $100,000 | Gray zone, run your numbers | At $80,000 profit with a $40,000 salary, gross savings are about $5,180; net roughly $3,180 to $3,680 after admin |
| $100,000 - $250,000 | Strong candidate | At $200,000 profit with a $90,000 salary, savings are about $9,500, well clear of costs |
| $250,000+ | Almost certainly worth it | Marginal benefit plateaus above the Social Security wage base, but the absolute savings are large |
The $80,000 row deserves a closer look because it is where most freelancers actually live. As a sole proprietor, SE tax is about $11,300. With a $40,000 salary, FICA is $6,120 and the $40,000 distribution escapes it, for $5,180 in gross savings. Subtract $1,500 to $2,000 for payroll software and the 1120-S filing, and you keep $3,180 to $3,680 a year. Worth doing, but thin enough that sloppy bookkeeping or a lowballed salary can erase it.
My take
I think the tax math is the easy part and the admin burden is the part people underestimate. Running payroll for yourself means quarterly filings, a W-2, a separate corporate return, and a compensation analysis the IRS can ask to see. None of that is hard, but it is all recurring, and it is all due whether you had a good year or not. The freelancers who regret the election are rarely the ones who misjudged the tax. They are the ones who misjudged how much they hate paperwork.
One practical note on timing: the election is made on Form 2553, due March 15 of the tax year it should apply to. Miss it and you are waiting a year, which is its own kind of expensive at $150,000 of profit.

How much does an S-corp save on self-employment tax?
On $120,000 of profit with a $70,000 salary, the election saves about $3,323 in federal tax before admin costs, leaving roughly $323 to $1,823 after payroll and filing fees. At $200,000 profit with a $90,000 salary, the saving is about $9,500.
At what profit does an S-corp become worth it?
Below about $50,000 in consistent net profit, the admin costs usually eat the savings. The $60,000 to $100,000 range is the gray zone where you should run your specific numbers. Above $100,000, the election is a strong candidate for most service businesses.
Do I have to pay myself a salary as an S-corp owner?
Yes, reasonable compensation for your services, paid as W-2 wages with payroll tax. You cannot set the salary artificially low to maximize the distribution; the IRS can recharacterize distributions as wages, as it did in Watson v. United States.
What is the deadline to elect S-corp status?
File Form 2553 by March 15 of the tax year you want it to apply to, or within 75 days of forming a new entity. Late elections are possible under Revenue Procedure 2013-30 if you meet the requirements.
Does the QBI deduction change the S-corp math?
Slightly. W-2 wages reduce the qualified business income base for the Section 199A deduction, which trims the savings a bit. In the comparisons above this effect is included, and the S-corp still wins at higher profit levels.
