Introduction
Can an S corporation election cut the tax bill of someone who works for themselves? Sometimes. It can also add payroll, filings and compliance rules a sole trader never faces.
An S corporation is a US federal tax election, not an Australian business structure. If you live in Australia, you still need to weigh those US rules against Australian tax residency and foreign-income obligations. Each system can tax the same income differently.
This guide covers salary versus distributions, shareholder status, tax benefits, compliance duties, cross-border issues and when to call a professional. All dollar figures are US dollars, and numbers are for 2026 unless noted.
Key Takeaways
- S corp treatment splits pay into payroll-taxed wages and distributions; income tax still applies.
- Working owners generally need reasonable wages run through payroll.
- Net savings must exceed payroll, filing, US state, legal and cross-border costs.
- Check how US S corp income interacts with Australian residency and foreign-income rules.
What Is an S Corp for a Self-Employed Person?
What an S corporation actually is
An S corporation is a tax classification, not a type of company. Under Subchapter S, the business passes income, losses, deductions and credits through to shareholders, who report them on personal returns, per the IRS.
An eligible LLC can elect S treatment with Form 2553 without changing its legal form. A separate Form 8832 is not required when the entity meets the requirements.
How it differs from common self-employed structures
An individual-owned single-member LLC is normally disregarded for federal income tax, and business activity goes on Schedule C. The same is broadly true of a sole proprietor. Forming an LLC does not create S treatment. Legal structure and tax election are separate decisions.
| Feature | Sole proprietor / default LLC | S corporation |
|---|---|---|
| Business income | Schedule C, all subject to self-employment tax | Passed through on Schedule K-1 |
| Owner pay | Profit is the owner's earnings | Wages via payroll plus distributions |
| Filing | Part of personal return | Form 1120-S plus payroll returns |
| Liability protection | None for a sole proprietor; LLC offers it | Depends on the underlying legal entity |
Basic eligibility considerations
The IRS requires:
- A domestic entity
- No more than 100 shareholders
- Only eligible shareholders: individuals, certain trusts and estates
- One class of stock
- No direct non-resident alien shareholders
The IRS sets no minimum income for electing S status. Also, US eligibility says nothing about whether the structure suits you under Australian tax law.
How S Corp Tax Benefits Work: Salary, Distributions, and Pass-Through Income
The self-employment tax starting point
Self-employment tax is 15.3%: 12.4% Social Security plus 2.9% Medicare, applied generally to 92.35% of net earnings, per the IRS. Social Security applies only up to the $184,500 earnings ceiling for 2026. Medicare has no ceiling, and an Additional Medicare Tax of 0.9% applies above set thresholds.
This is separate from US federal and state income tax, and from Australian tax. An S corp does not remove any of those obligations.
Salary and distribution mechanics
An active shareholder-employee takes reasonable wages through payroll, with employment taxes withheld. Remaining profit can be distributed without payroll tax. That wage-versus-distribution split is where the employment-tax saving comes from.
Distributions do not replace wages. The IRS can recharacterise them as compensation. In David E. Watson, P.C. v. United States (8th Cir. 2012), an owner who paid himself only $24,000 in salary had reasonable compensation set at $91,044.
Pass-through taxation and personal reporting
Taxable income flows to shareholders on Schedule K-1 whether or not cash leaves the company. You can owe tax on profit that stays in the business bank account.
Other potential tax benefits
- QBI deduction: now permanent, up to 20% of qualified business income, with income and wage limits. Shareholder wages are not QBI.
- Retirement: the 2026 individual 401(k) deferral limit is $24,500. Contributions depend on W-2 pay, not distributions.
- Health insurance: premiums for more-than-2% shareholders go through W-2 Box 1 under specific conditions.
The trade-off: lower wages shrink retirement capacity and Social Security earnings records.
Illustrative cost-benefit example
This is a hypothetical, not advice. Assume $150,000 net profit, a reasonable salary of $80,000, and $70,000 in distributions.
| Item | Default taxation | S corporation |
|---|---|---|
| Wages subject to SE or payroll tax | ~$138,525 (92.35% of profit) | $80,000 |
| Approx. employment taxes | ~$21,195 | ~$12,240 |
| Gross difference | ~$8,955 | |
| Added costs | None | Payroll, 1120-S, bookkeeping, state fees |
Employment tax in the S corp column is 15.3% of wages, covering employer and employee halves. The exact result shifts with salary, state tax, QBI and fees. A California S corp, for example, faces 1.5% tax and an $800 minimum.
S Corp Shareholder Insights: Ownership, Compensation, and Income Reporting
Who is a shareholder, and when is the owner also an employee
A shareholder holds an ownership interest. An owner who performs services is generally also a W-2 employee.
IRS guidance treats corporate officers as employees, except where they perform no or only minor services and are not entitled to pay. A passive shareholder faces different payroll duties.
Determining reasonable compensation
The IRS looks at training, experience, duties, time devoted, comparable pay, and payments to non-shareholder employees. No percentage safe harbour exists. Document your position:
- Comparable pay research for similar roles
- Written job duties and responsibilities
- Time records of hours worked
- Shareholder decisions on pay
- An annual compensation review
Ownership restrictions, basis and losses
Only eligible shareholders may hold shares, and distributions must respect the one-class-of-stock rule. Direct non-resident alien ownership is prohibited, and an ineligible shareholder can end S status from that date.
Basis matters too. Income raises stock basis and distributions lower it, so how you treat a distribution depends on stock basis.
Loss deductions run through basis (Form 7203), at-risk (Form 6198), passive activity (Form 8582) and excess business loss (Form 461) limits. Keep clean records so distributions are not confused with wages, loans or reimbursements.
Passive income
An S corp can earn passive income. If it has accumulated earnings and profits and passive investment income exceeds 25% of gross receipts for three consecutive years, S status terminates.
Who Should Consider S Corp Tax Treatment, and Who Should Not?
When it may be worth modelling an S corp election
- Steady profit well above a defensible salary
- A long-term plan to run the business
- Owner-operated consultants, contractors and professional service providers
Duties and industry shape what counts as reasonable pay.
When it may not suit
- Low, irregular or loss-making profit that cannot absorb recurring costs
- Complex ownership or non-resident shareholders
- Significant passive income
- Cross-border reporting
Decision checklist
Compare projected payroll-tax savings against:
- Payroll processing and bookkeeping
- Form 1120-S preparation and US state filings
- Registered agent or corporate costs
- Retirement and QBI effects
- Australian tax consequences
No universal income level makes an S corp worthwhile. Salary, profit, US state costs and compliance burden decide it.
How to Elect and Manage S Corp Status
Confirm eligibility and file the election
Confirm eligibility, form or keep the legal entity, then file Form 2553 with shareholder consent. The deadline is two months and 15 days after the tax year begins, or earlier in the prior year. Relief under Revenue Procedure 2013-30 can cover late elections within three years and 75 days.
The IRS confirms acceptance with notice CP261. Check state requirements separately: New York uses Form CT-6, and New York City does not recognise the S election.
Establish compliant payroll
Set a defensible salary, run payroll, withhold and remit taxes, and issue a W-2. Taking only draws while working in the business invites reclassification, interest and penalties. Deposit penalties run from 2% to 15%, and the Trust Fund Recovery Penalty can hold responsible persons personally liable.
Complete recurring filings
- Form 1120-S and K-1s: generally due the 15th day of the third month after year-end; Form 7004 gives six months
- Form 941: quarterly
- Forms 940 and W-2/W-3: generally 31 January
- Estimated tax: Form 1040-ES where you expect to owe $1,000 or more
A late or incomplete 1120-S costs $255 per shareholder per month, up to 12 months, for returns due in 2026. Verify all dates with the IRS and your state.
Records and annual review
Maintain records that support the election and any distributions:
- Separate business bank account
- Accurate books and payroll records
- Distribution approvals and basis tracking
- Minutes or resolutions
Reliable books show whether cash is available to distribute and whether pay stays reasonable.
Reassess each year, and after changes in revenue, duties, ownership, residency or jurisdiction. Speak to a tax professional before changing entity treatment, taking large distributions, adding shareholders or expanding abroad.
Australian and Cross-Border Considerations for Self-Employed Owners
An S corporation is not an Australian company type
An S corp does not replace a sole trader, partnership or Pty Ltd. Australian entity options include the Pty Ltd, public company, partnership, trust and registered foreign company branch, each with ASIC and ABN registration.
Compare the US election with Australian structure, residency, controlled foreign company (CFC) and anti-avoidance rules using current ATO guidance. ATO guidance explains that income of a foreign company controlled by Australian residents can be attributed without any cash distribution.
Tax residency, source and treaty questions
- Australian residents generally declare worldwide business income, translated into Australian dollars.
- The foreign income tax offset requires foreign tax actually paid and relevant assessability conditions. US tax paid is not an automatic credit.
- Under TR 2018/5, central management and control in Australia can make a US company Australian resident.
- Australian tax residency alone does not bar a US citizen or resident alien from S shareholder status. Direct non-resident alien ownership is barred.
- The 1982 Australia-US treaty, amended in 2001, covers permanent establishment and dividends (generally capped at 15% for qualifying individuals).
Confirm S corp classification against current ATO guidance rather than assuming it maps to a familiar Australian form. Do not rely on guidance written for US disregarded LLCs, and never elect based on a US payroll calculation alone.

Frequently Asked Questions
Do S corporations have to pay self-employment taxes?
No, not on distributions. Shareholder-employee wages carry payroll taxes instead, and the result depends on your role and current IRS rules.
Who is exempt from paying self-employment tax?
Employees paying payroll tax on wages, and some passive owners and limited partners, may fall outside self-employment tax. Exceptions are narrow, so verify them for your situation.
Does S Corp income count as personal income?
Yes, for tax reporting. Income passes through on Schedule K-1 whether or not it is distributed. Australian-based owners also face separate Australian residency and foreign-income rules.
Can you have passive income in an S corp?
Yes, though passive activity rules and the 25% passive investment income test can threaten status where earnings and profits have accumulated.
Who is considered a shareholder in an S Corp?
An eligible owner holding stock, such as an individual, certain trusts or an estate. A working shareholder is also an employee, while a passive one may not be.
