The Core Idea: Split Profit Into Salary and Distribution
The S-Corp election is the single most powerful tax-saving move available to profitable self-employed owners, and the mechanism is simple. As a sole proprietor or single-member LLC, you pay 15.3% self-employment tax on every dollar of net profit. As an S-Corp, you split that profit into two pieces: a reasonable salary subject to payroll taxes, and a distribution that pays no SE tax at all.
The salary portion still incurs the same 15.3% combined payroll tax — 7.65% withheld from your paycheck as the employee and 7.65% paid by the S-Corp as the employer. The magic happens on the distribution portion. That money passes to you free of the 15.3% SE tax.
The 2026 Math on $100,000 of Profit
Consider a consultant who converts a single-member LLC to an S-Corp and earns $100,000 in net profit. They set a reasonable salary of $50,000 and take the remaining $50,000 as a distribution.
| Structure | SE/Payroll Tax | SE Tax on Distribution | Total |
|---|---|---|---|
| Sole proprietor (no S-Corp) | $100,000 × 92.35% × 15.3% = $14,130 | Included above | $14,130 |
| S-Corp ($50k salary + $50k distribution) | $50,000 × 15.3% = $7,650 | $0 | $7,650 |
| Savings | $6,480 |
The raw savings of $6,480 is real, but it is not free money. Running an S-Corp adds costs: payroll service fees of roughly $500–$1,500 per year, a separate Form 1120-S tax return ($800–$2,000 in preparation fees), and state franchise or S-Corp fees. Net savings typically land around $4,000–$5,000 on $100,000 of profit.
Where the Breakeven Point Sits
Below a certain profit level, the fixed costs of S-Corp compliance exceed the SE-tax savings. Above it, the savings compound fast. Here is the picture for 2026:
- $40,000 profit: SE-tax savings ≈ $2,600, minus $2,000 in costs = $600 net savings — barely worth the complexity
- $60,000 profit: SE-tax savings ≈ $4,200, minus $2,000 in costs = $2,200 net savings
- $80,000 profit: SE-tax savings ≈ $6,000, minus $2,000 in costs = $4,000 net savings
- $120,000 profit: SE-tax savings ≈ $10,000, minus $2,500 in costs = $7,500 net savings
My rule of thumb: once net profit reliably exceeds $60,000–$80,000, the S-Corp election almost always pays off. Below that, the paperwork outweighs the benefit.
The Reasonable Salary Requirement
The IRS does not let you set a $1 salary and take $99,999 as a distribution. S-Corp owner-employees must pay themselves "reasonable compensation" — what a non-owner would be paid for the same duties — before taking any distribution. Reasonable salary depends on industry, role, hours, and market rates, and the IRS challenges salaries that look engineered to dodge payroll tax.
Common benchmarks: a software consultant in a major metro might justify $70,000–$90,000; a bookkeeper might justify $45,000–$60,000; a physician owner might justify $200,000+. Document how you arrived at the salary — salary surveys, competitor postings, and time logs all support your number if the IRS asks.
Retirement and Deduction Planning Inside an S-Corp
S-Corp owners can still open a Solo 401(k) with a 2026 contribution limit up to $69,000, or a SEP-IRA based on salary. The S-Corp can also deduct Section 179 expensing up to $1,110,000 on equipment purchases, and the owner's health insurance premiums are deductible as an adjustment to income. The Tax Deduction Finder helps identify deductions that lower profit before the salary-plus-distribution split.
One nuance: Solo 401(k) employer contributions inside an S-Corp are based on W-2 salary, not total profit. A low salary limits how much you can contribute on the employer side, which is another reason to set salary at a defensible level rather than the absolute minimum.
The Bottom Line
The S-Corp salary-plus-distribution strategy is not magic — it is arithmetic. On $100,000 of profit with a $50,000 salary, you save roughly $6,480 in SE tax, netting $4,000–$5,000 after compliance costs. The strategy pays off once profit reliably exceeds $60,000–$80,000. Pay a defensible market salary, run real payroll, and let the distribution portion escape the 15.3% SE tax. Model your own numbers with the Self-Employment Tax Calculator and identify deductions with the Tax Deduction Finder before you file Form 2553.
