Guaranteed payments vs. salary is really a question your entity answers for you: partnerships and multi-member LLCs taxed as partnerships pay working owners through guaranteed payments, while S-corporations and C-corporations pay owner-employees a salary through payroll. From there the two diverge on self-employment tax versus FICA, on withholding, on retirement plan math, on health insurance treatment, and on the qualified business income deduction. Those differences can move an owner’s annual tax bill by thousands of dollars, which is why the choice of entity — and, inside an S-corp, the size of the salary — gets so much attention.
What Each One Is
Guaranteed payments come from Section 707(c) of the Internal Revenue Code. The partnership agrees to pay a partner a fixed amount for services or for the use of capital, and that amount is owed whether the business made money or not.1Office of the Law Revision Counsel. 26 U.S. Code 707 – Transactions Between Partner and Partnership The partnership deducts the payment as a business expense, which reduces the ordinary income that flows through to all partners on their K-1s.2Internal Revenue Service. Publication 541 – Partnerships Multi-member LLCs taxed as partnerships use the same mechanism, usually spelled out in the operating agreement.
A salary is what an S-corp or C-corp pays a shareholder who works in the business. The IRS treats a working shareholder as an employee, and the corporation must set a reasonable salary for that person before taking distributions or dividends.3Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers “Reasonable” means what someone with similar duties, training, and experience would earn at a comparable business. The tax courts weigh the owner’s role and time commitment, comparable market pay, the pattern of distributions, and what non-shareholder employees at the business earn. A tiny salary paired with large regular distributions is the pattern most likely to draw an audit.
Employment Taxes: Where the Money Is
This is where most of the real dollars sit. A partner receiving guaranteed payments owes self-employment tax on those payments, and a general partner also owes self-employment tax on their distributive share of partnership income.4Internal Revenue Service. Entities The rate is 15.3% — 12.4% for Social Security and 2.9% for Medicare — and the partner pays all of it because there is no employer on the other side.5Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet
The 12.4% Social Security piece only applies up to the wage base, which is $184,500 in 2026.6Social Security Administration. Contribution and Benefit Base Above that, only the 2.9% Medicare tax continues. An additional 0.9% Medicare tax also applies to self-employment income above $200,000 for single filers or $250,000 for joint filers.7Internal Revenue Service. Questions and Answers for the Additional Medicare Tax Partners can deduct the employer-equivalent half of their self-employment tax (7.65%) when calculating adjusted gross income, which trims income tax but does nothing to the self-employment tax itself.8Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
A corporate owner-employee pays FICA instead, and it’s split. The corporation withholds 6.2% Social Security and 1.45% Medicare from the paycheck and pays a matching 6.2% and 1.45% from its own funds.9Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates The same wage base and additional Medicare thresholds apply. The real advantage sits with the S-corp: distributions the shareholder takes on top of a reasonable salary carry no FICA and no self-employment tax. A partner in an economically identical business would pay self-employment tax on the equivalent distributive share. That gap is the main reason owners elect S-corp status, and it’s why the IRS presses so hard on reasonable compensation.
Corporations also owe Federal Unemployment Tax on the first $7,000 of each employee’s wages at a base rate of 6.0%, usually reduced to 0.6% after state unemployment credits.10Internal Revenue Service. Topic No. 759, Form 940 – Employers Annual Federal Unemployment Tax Return Partnerships don’t owe FUTA on guaranteed payments. Small in dollars, but a filing obligation on the corporate side.
Reporting, Withholding, and Estimated Taxes
Nothing is withheld from a guaranteed payment. The partnership files Form 1065 and reports each partner’s guaranteed payments on Schedule K-1 in Box 4 (4a for services, 4b for capital), and the partner picks those up on Schedule E of the personal return.11Internal Revenue Service. Partners Instructions for Schedule K-1 (Form 1065) The partner covers income tax and the full 15.3% self-employment tax through quarterly estimated payments, due April 15, June 15, September 15, and January 15. Miss those deadlines and you owe an underpayment penalty unless the shortfall is under $1,000, or you’ve paid at least 90% of the current year’s tax or 100% of the prior year’s.12Internal Revenue Service. Topic No. 306, Penalty for Underpayment of Estimated Tax First-year partners routinely underestimate because they’re not used to funding the whole 15.3% themselves.
Salary runs through payroll. The corporation issues a W-2, withholds federal and state income tax plus the employee share of FICA, and remits everything, including its employer match, to the Treasury. Quarterly reporting happens on Form 941, annual federal unemployment on Form 940.13Internal Revenue Service. Forms 940, 941, 944 and 1040 (Sch H) Employment Taxes Owners taking large distributions on top of a modest salary may still need to make estimated payments on the distribution income, but the salary itself arrives with withholding built in.
Retirement Contributions
Compensation type drives the contribution ceiling. For 2026, a SEP IRA allows up to 25% of compensation capped at $72,000. A solo 401(k) allows an employee elective deferral of up to $24,500 (or $32,500 at age 50 and older) plus employer contributions up to 25% of compensation, with a combined ceiling of $72,000 ($80,000 at 50 and older).
For S-corp owners, the base is W-2 salary. A $60,000 salary supports a $15,000 SEP contribution; a $120,000 salary supports $30,000. That’s a real reason not to set the salary as low as possible if retirement saving is a goal.
Partners calculate contributions from net self-employment earnings after subtracting the deductible half of self-employment tax, and the contribution itself reduces the base it’s calculated from. The circular math works out to roughly 20% of net self-employment earnings for a SEP rather than a clean 25%. The solo 401(k) employee deferral piece ($24,500) doesn’t have that problem, which is why solo 401(k) plans often let self-employed people put more away at moderate income levels than a SEP does.
Health Insurance
Both paths let owners deduct health insurance premiums, but through different mechanics.
In a partnership, premiums paid on a partner’s behalf are treated as additional guaranteed payments. They go on the K-1, get included in self-employment income, and carry self-employment tax. The partner then takes the self-employed health insurance deduction on the personal return to pull the premium back out of adjusted gross income, provided there’s enough net self-employment income and the partner isn’t eligible for a spouse’s employer plan.
An S-corp shareholder who owns more than 2% has the corporation pay the premiums and add them to Box 1 wages on the W-2, so they’re subject to income tax. Those premium amounts are exempt from Social Security, Medicare, and FUTA.14Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues The owner claims the self-employed health insurance deduction on the personal return, same as a partner. The end result looks similar, with one meaningful difference: the S-corp owner avoids employment tax on the premium amount, while the partner pays self-employment tax on it.
The QBI Deduction
Section 199A can deduct up to 20% of qualified business income from pass-through entities, and it treats both guaranteed payments and salary as outside the QBI base. Guaranteed payments for services are explicitly excluded.15Internal Revenue Service. Qualified Business Income Deduction A $100,000 guaranteed payment produces zero QBI deduction on that amount, though the partner’s distributive share of partnership income still qualifies. Salary is likewise excluded because it’s W-2 income, not K-1 pass-through income. The S-corp’s remaining profit that passes through as distributions on the K-1 does count.
Above roughly $203,000 of taxable income for single filers or $406,000 for joint filers, the QBI deduction gets capped at the greater of 50% of W-2 wages paid by the business, or 25% of W-2 wages plus 2.5% of the cost basis of qualified business property. An S-corp that pays no salary can lose its QBI deduction entirely above those thresholds even with substantial pass-through income, which flips the usual “keep salary low” instinct on its head. For high-income S-corp owners, salary has to be balanced against the QBI wage limit as well as against reasonable compensation and FICA.
Partners have no W-2 wages of their own to feed the limit calculation. If the partnership has employees, their wages count; if the only workers are the partners themselves, high-income partners in service businesses can end up with a badly limited QBI deduction.
Which One to Choose
Three factors usually decide it: total employment tax, administrative burden, and flexibility.
On employment tax, S-corps come out ahead when business income comfortably exceeds a reasonable salary. Distributions above the salary escape FICA, while a partner earning the same total pays self-employment tax on guaranteed payments and distributive share alike. The savings grow with income up to the Social Security wage base, then narrow because only the 2.9% Medicare gap remains above $184,500.
On administration, partnerships are simpler. No payroll system for guaranteed payments, no Form 941, no FUTA return, no withholding deposits. Partners handle their own taxes through estimated payments. A two-person LLC that doesn’t want payroll infrastructure has a real reason to stay a partnership for tax purposes.
On flexibility, partnership agreements can allocate income, losses, and guaranteed payments in almost any configuration the partners agree to. S-corps must pay one class of salary and distribute profits in proportion to share ownership, and they carry restrictions on the number and type of shareholders and on classes of stock.
Neither structure wins across the board. An owner netting $80,000 a year may find the payroll costs and administrative overhead of an S-corp eat up most of the FICA savings. An owner netting $300,000 might save $10,000 or more per year in employment tax by running an S-corp with a reasonable salary. Running your own numbers, at your actual income, is what settles the question.
