S-Corp Tax Savings
S-Corp vs Partnership: Which Cuts Self-Employment Tax on a Two-Owner Business?
Two people start a consulting firm and split the profit down the middle. As a partnership, each active owner pays self-employment tax on their entire half. An S-Corp lets them split that half into a salary and a distribution, and only the salary carries payroll tax. That one difference is worth thousands a year. Here is the 2026 math, and the recent court cases that quietly closed the partnership escape hatch.
A question I get from two-owner businesses runs something like this. "We formed an LLC and we file a partnership return. Our accountant mentioned an S-Corp election could save on taxes. Is that real, or is it one of those internet things?" It is real, and for an active two-owner business the reason is almost always self-employment tax. The owners below are theoretical, not actual EntityIQ clients, but the mechanics are the same ones I run for real ones.
How a partnership taxes an owner who works in the business
A partnership does not pay income tax itself. It files Form 1065 and passes each partner a Schedule K-1 with their share of the profit. For a general partner who actively runs the business, that whole distributive share of ordinary trade-or-business income is net earnings from self-employment under IRC §1402(a), along with any guaranteed payments for services under §707(c). That amount runs through the self-employment tax of §1401, which is 15.3% on 92.35% of net earnings. The 12.4% Social Security piece stops at the wage base, which the Social Security Administration set at $184,500 for 2026. The 2.9% Medicare piece has no ceiling, and a 0.9% Additional Medicare tax stacks on above $200,000 single or $250,000 joint.
The key point is that a partnership gives an active owner no way to carve out a piece of the profit that escapes this tax. There is no "salary versus distribution" line inside a partnership for a working general partner. Whatever the business earns and passes through to that partner is exposed.
The limited-partner exclusion, and why it may not save you
There is one statutory exception. IRC §1402(a)(13) excludes the distributive share of a limited partner, other than guaranteed payments for services. On paper, that looks like a way for an LLC member or a limited partner to take profit free of self-employment tax. In practice, the exclusion is narrower than most people assume, and the IRS has been winning cases on it.
In Renkemeyer, Campbell & Weaver, LLP v. Commissioner, 136 T.C. 137 (2011), the Tax Court held that partners in a law firm who performed the firm's legal services were not limited partners as such, so their distributive shares were self-employment income. More recently, in Soroban Capital Partners LP v. Commissioner, 161 T.C. No. 12 (2023), the court held that holding a state-law limited-partner title is not enough. It applied a functional-analysis test that looks at what the owner actually does. An owner who manages the business, makes its decisions, and earns income from their own work is not the passive investor the exclusion was written for. If you and your co-owner both work in the business full time, planning around §1402(a)(13) is a bet against a line of cases the government keeps winning.
How an S-Corp changes the math
An S-Corp is still a pass-through, so the profit lands on the owners' personal returns either way. What changes is the employment tax. An S-Corp owner who works in the business is an employee and takes a reasonable salary subject to FICA under §3121. The rest of the profit comes through as a distribution that is not subject to FICA, self-employment tax, or the Additional Medicare tax. Rev. Rul. 59-221 confirmed decades ago that an S-Corp shareholder's pass-through share is not self-employment income. So the same profit that a partnership taxes in full is split, and only the salary slice carries the 15.3%.
The catch is "reasonable." The salary has to reflect what the work is worth, a standard the courts have enforced against owners who paid themselves too little, as in David E. Watson, P.C. v. United States, 668 F.3d 1008 (8th Cir. 2012). Set it too low and you invite an audit. Set it too high and you erase the savings. The number below is defensible for many service businesses but always depends on the facts.
The 2026 numbers, side by side
Both structures below cover the same business. It nets $300,000 of ordinary profit, split evenly between two owners who both work in it. Under the partnership, each owner's $150,000 share is fully exposed to self-employment tax. Under the S-Corp, each owner takes a $65,000 salary and $85,000 as a distribution. Figures use 2026 rates and are rounded.
As a partnership
Full share taxed at 15.3%
No salary/distribution split. Every dollar of the active share is exposed.
As an S-Corp
Only the salary carries FICA
The $85,000 distribution per owner carries no employment tax.
Combined employment-tax savings
~$22,500 / year
$42,388 partnership SE tax minus $19,890 S-Corp FICA. After budgeting roughly $3,500 for two payrolls and an 1120-S, the net is close to $19,000.
Where the partnership can still win
The S-Corp is not free money, and a few things push the other way. An S-Corp adds real compliance: two payrolls, quarterly filings, and a separate Form 1120-S. On a low-profit business those costs can swallow the savings, which is the whole point of running a break-even before you file. A partnership is also more flexible on how it splits income, allocates debt to basis, and admits or buys out owners. S-Corps have rigid rules here, including a single class of stock and per-share, per-day allocations.
Watch the §199A qualified business income deduction too, because it can move in both directions. Paying yourself a W-2 salary in an S-Corp reduces qualified business income dollar for dollar, which shrinks the 20% deduction. At the same time, the wages the S-Corp pays help you clear the W-2 wage limitation that applies to higher-income owners. Guaranteed payments a partnership makes to its partners are never QBI, so a partnership is not automatically ahead here either. And if you operate in a state with a pass-through entity tax, both structures may qualify for the SALT-cap workaround, so that is rarely the deciding factor.
How to decide
If both owners work in the business and profit comfortably exceeds each owner's reasonable salary, the S-Corp usually wins on employment tax, often by five figures a year for a business at this profit level. If one owner is a genuine passive investor, if profit is thin, or if you need flexible allocations that an S-Corp cannot provide, the partnership may be the better home. The honest way to settle it is to run both, with your actual profit and defensible salaries, rather than trusting a rule of thumb.
