The short answer

Once your business is an S corporation, you wear two hats. If you work in the business, you are an employee who must be paid a reasonable salary through payroll, with Social Security and Medicare taxes withheld and paid. You are also a shareholder: the corporation files Form 1120-S, and your share of its income, deductions, and credits is reported to you on Schedule K-1 and taxed on your own return. Profit you receive beyond your salary can be paid as distributions, which are not wages.

Reasonable salary: what the IRS looks at

The IRS says an S corporation must pay reasonable compensation to a shareholder-employee for services before making non-wage distributions to that shareholder, and it can reclassify distributions as wages. The IRS lists these factors, among others:

  • Training and experience
  • Duties and responsibilities
  • Time and effort devoted to the business
  • Dividend history
  • Payments to non-shareholder employees
  • Timing and manner of paying bonuses to key people
  • What comparable businesses pay for similar services
  • Compensation agreements
  • The use of a formula to determine compensation

The IRS also explains that the key is the source of the business's gross receipts: to the extent they come from the work of other employees or from capital and equipment, payments to the owner can properly be distributions. Reasonable compensation will never be more than the amount the shareholder actually receives.

Salary vs. distributions

Salary (wages)Distributions
How it is paidThrough payroll, reported on Form W-2Paid out of the corporation's profits, not through payroll
Social Security and Medicare taxesYes — 6.2% each from employee and employer for Social Security (up to the wage base: $176,100 for 2025, $184,500 for 2026) and 1.45% each for Medicare, plus Additional Medicare Tax withheld on wages over $200,000No
Income taxYes, withheld from payThe income is already taxed through Schedule K-1; distributions are generally not taxed again up to your stock basis
Counts as qualified business income (QBI)?NoDistributions are not the measure — your K-1 share of business income is what can be QBI

Form 1120-S and Schedule K-1

ItemRule
Due date15th day of the 3rd month after the tax year ends — March 16, 2026 for calendar-year 2025 (March 15 was a Sunday); March 15, 2027 for calendar-year 2026
ExtensionForm 7004 — generally an automatic 6-month extension of time to file, not to pay
Late-filing penaltyFor each month or part of a month (up to 12 months) the return is late, multiplied by the number of shareholders: $255 for returns required to be filed in 2026 (calendar-year 2025 returns; Rev. Proc. 2024-40 and the 2025 instructions) and $260 for returns required to be filed in 2027 (calendar-year 2026 returns; Rev. Proc. 2025-32). More applies if tax is due
Schedule K-1Shows each shareholder's share of income, deductions, and credits; an individual generally reports it on Schedule E (Form 1040), Part II
Officer payReported on Form 1120-S, line 7 (from Form 1125-E when required)

Health insurance for more-than-2% shareholders

Under the 2025 Form 1120-S instructions, health insurance the corporation pays for a more-than-2% shareholder (including the shareholder's spouse, dependents, and children under age 27) is treated as wages: it is included in box 1 of the shareholder's Form W-2 and shown as an information item in box 14. The shareholder may then be allowed to deduct it on Schedule 1 (Form 1040), line 17, if the self-employed health insurance requirements are met.

Stock basis and Form 7203

Your stock basis limits the losses you can deduct and determines whether a distribution is tax-free. You must file Form 7203 with your return if you claim a deduction for your share of an S corporation loss, receive a non-dividend distribution, dispose of S corporation stock, or receive a loan repayment from the S corporation.

Example (illustrative, 2026)

Ana is the only shareholder of an S corporation and works in it full time. Before her pay, the business earns $120,000. Based on what similar businesses pay for her role, she sets her salary at $70,000.

StepAmount
Salary, run through payroll$70,000
Social Security and Medicare on the salary (employee + employer, 15.3%)$10,710
Employer share of those taxes (deducted by the corporation)$5,355
Business income on her Schedule K-1 ($120,000 − $70,000 − $5,355)$44,645

Ana pays income tax on her wages and on the $44,645 from her K-1. If the same $120,000 were Schedule C profit, self-employment tax would be about $16,955 ($120,000 × 92.35% × 15.3%). This comparison is simplified: it ignores unemployment taxes, payroll and tax-preparation costs, state taxes, retirement contributions, and the QBI deduction — which can be smaller because her wages are not QBI.

Making or fixing the election

  • Timing: to take effect for the current tax year, Form 2553 generally must be filed no more than 2 months and 15 days after the beginning of that tax year (or at any time during the prior tax year).
  • An LLC electing S status files Form 2553; under the Form 2553 instructions it does not also need to file Form 8832.
  • Late elections: relief under Rev. Proc. 2013-30 is generally available within 3 years and 75 days of the intended effective date if the conditions in the Form 2553 instructions are met, including reasonable cause and consistent reporting by all affected shareholders.

Common mistakes

  • Taking no salary while working in the business and taking only distributions.
  • Missing the Form 1120-S deadline — the penalty is figured per shareholder, per month.
  • Leaving owner health insurance off the W-2 for a more-than-2% shareholder.
  • Not tracking stock basis or skipping Form 7203 when it is required.
  • Assuming K-1 income needs no estimated tax. Payroll withholding covers your wages, but you may still owe estimated tax on K-1 income.
  • Mixing personal and business money, which makes it hard to separate wages, distributions, and expenses.

California considerations

California and other states may tax S corporations and their shareholders differently from the federal rules. AskLinTax has not verified California's current S corporation tax rates, minimum taxes, or filing requirements against Franchise Tax Board sources for this guide, so this guide does not state them. Check the California Franchise Tax Board before relying on any specific amount.
