S-Corp vs Sole Proprietorship: Does Electing S-Corp Status Actually Save You Money in 2026?

A freelance software developer nets $120,000 on a Schedule C and hands over roughly $17,000 in self-employment tax before a single dollar of income tax comes off the top. Every spring she asks the same question I hear constantly: would forming an LLC and electing S-Corp status cut that bill, and by how much? The answer is yes for her and no for plenty of others, and the difference is entirely about how much profit a reasonable salary leaves behind. The owners in this article are theoretical, not actual EntityIQ clients.

What a sole proprietor actually pays

A sole proprietor reports business profit on Schedule C and carries it to the Form 1040. On top of income tax, that profit is hit with self-employment tax on Schedule SE. Under IRC §1401, the rate is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare, applied to 92.35% of net profit under §1402(a)(12). The 12.4% piece stops at the Social Security wage base, which the Social Security Administration set at $184,500 for 2026. The 2.9% Medicare piece has no cap. You do get to deduct half of the self-employment tax above the line under IRC §164(f), which softens the income-tax side but does nothing to the payroll tax itself.

On $120,000 of profit, net earnings from self-employment are $110,820, and 15.3% of that is $16,955. Because the developer is well under the wage base, every dollar of profit carries the full rate. That is the number an S-Corp is trying to shrink.

What changes when you elect S-Corp

An S-Corp is not a different kind of business, it is a tax election. An LLC or corporation files Form 2553 to be taxed under Subchapter S, and the owner becomes a shareholder-employee. The company runs payroll and pays that owner a salary, which carries FICA just like any job. Whatever profit is left flows out as a distribution. Distributions of an S-Corp's earnings under IRC §1368 are not wages and are not subject to FICA, self-employment tax, or the 0.9% Additional Medicare tax. That is the entire source of the savings. Only the wages the corporation pays the shareholder-employee carry employment tax, which is why the IRS insists that wage be reasonable rather than zero.

That reasonable-compensation rule is the guardrail on the whole strategy. A shareholder-employee must receive reasonable compensation for services before taking distributions, a rule the IRS has enforced since Rev. Rul. 74-44 and courts upheld in Watson v. United States, 668 F.3d 1008 (8th Cir. 2012), where an accountant's $24,000 salary was recharacterized to about $91,000. Set the salary too low and the IRS reclassifies distributions as wages, adds back the payroll tax, and can pile on penalties and interest. So the real question is never "salary of zero versus distribution of everything." It is how much profit a defensible salary leaves on the distribution side.

Two owners, opposite answers

Both owners below run a service business and take a reasonable salary, then distribute the rest. The only thing that differs is how much profit there is to work with. Numbers use 2026 figures and are rounded.

Why the low-profit owner loses

Owner A has $50,000 of distribution room, and every dollar of it dodges the 15.3% rate. That is $6,245 of employment-tax savings, and after roughly $2,000 a year for payroll, an 1120-S return, and quarterly filings, she keeps about $4,245. Owner B has the same idea and almost no room to run it. A $35,000 salary on $45,000 of profit is about as low as most preparers will defend, which leaves only $10,000 of distribution. The savings on that is barely $1,000, and the cost of running an S-Corp swallows it whole. The election turns a $45,000 sole proprietorship into a more expensive version of itself.

There is no bright-line number in the tax code, but the math rarely works below roughly $45,000 to $50,000 of net profit. At that level a reasonable salary eats most of the profit, so there is little distribution room to save on, and the extra cost of payroll, an 1120-S return, and quarterly filings usually runs $1,500 to $3,000 a year. Once net profit clears about $80,000 to $100,000 and can support a genuine split between salary and distribution, the election usually pays for itself several times over.

The parts a payroll comparison misses

Two more factors can move the answer, and both belong in the same calculation. The first is the §199A qualified business income deduction. It is 20% of qualified business income, and wages you pay yourself are not QBI, so a higher salary shrinks the deduction. But above the 2026 taxable income thresholds of $201,750 single and $403,500 joint, the deduction is capped by 50% of W-2 wages, and an S-Corp salary can create the wage base a sole proprietor lacks. Which effect wins depends on your income, so run it, do not guess.

The second is state and local cost. Some states impose an entity-level franchise, net-worth, or minimum tax on S-Corps that a sole proprietor never pays. California charges a 1.5% tax on S-Corp net income with an $800 annual minimum, and other states have their own versions. Those charges come straight off the federal savings and can be enough to flip a marginal case. A day job also matters. If you already earn above the $184,500 wage base at another employer, most of your sole-prop self-employment tax is only the 2.9% Medicare slice to begin with, which shrinks the prize before you start.

The short version is that the S-Corp beats the sole proprietorship exactly when your profit is high enough to pay a defensible salary and still leave real money for distributions. Below that line the paperwork wins. Rather than eyeball it, run your own numbers in the EntityIQ S-Corp tax calculator, which accounts for your salary, the wage base, and the QBI deduction, then generates a pre-filled Form 2553 if the election makes sense. For the mechanics once you decide, see our guides on the reasonable compensation rules and how to file Form 2553.
