An S corporation is more than an election.

Tax treatment and eligibility come first.

S corporations generally pass income, losses, deductions and credits through to shareholders for federal tax purposes. Shareholders report their allocated items on personal returns; certain built-in gains and passive income can still produce entity-level tax.

Eligibility includes domestic status, no more than 100 shareholders, eligible owners and one class of stock. Partnerships, corporations and nonresident aliens generally cannot be shareholders; certain trusts and estates can qualify. Some types of corporations are ineligible. This is a starting checklist, not a determination that your ownership arrangement qualifies. IRS: S corporations.

An LLC is a state-law entity, while S status is a federal tax election. An eligible LLC can elect corporate tax treatment and, if the requirements are satisfied, S status; organizing an LLC does not automatically make it an S corporation. IRS: LLC tax classification.

Consider the work the election creates.

Form 2553 generally must be filed within two months and 15 days after the start of the tax year for which the election is intended, or during the preceding tax year. Required shareholder consent, the effective date and existing tax classification matter. First-year and late-election situations need specific analysis; relief is conditional, not automatic. Retain filing evidence and the IRS response. IRS: Form 2553 instructions.

Before deciding, compare the expected business activity, owner roles, payroll administration, accounting and return responsibilities. For a Philadelphia practice or a business with work across jurisdictions, include a separate state/local review rather than treating the federal answer as the entire answer. Entity Structuring addresses the tax-classification engagement; counsel handles legal formation, governance and ownership agreements.

Reasonable compensation depends on the work.

The IRS requires reasonable compensation for services a shareholder-employee provides before non-wage distributions are made to that shareholder-employee. The analysis looks at what the owner actually does and how the business generates revenue. Relevant factors include duties, experience, time devoted, comparable pay and compensation arrangements. Administrative work can count even when other staff generate the revenue.

There is no universal salary-to-distribution percentage. A consultant delivering the client work, a practice owner managing staff and an investor who performs no services present different facts. Document the actual role and supporting information. The IRS can reclassify payments labeled as distributions as wages subject to employment taxes. IRS: shareholder compensation guidance.

Salary, pass-through income and distributions are different.

Wages compensate an employee for work. Allocated business income and cash distributed to an owner are separate concepts: a Schedule K-1 reports allocated items and distributions, but does not by itself establish the taxable amount of a distribution.

A non-dividend distribution is generally tax-free to the extent of the shareholder’s stock basis; amounts above stock basis can create capital gain. Debt basis does not shelter a distribution. Prior C-corporation history can complicate the treatment. Shareholders are responsible for tracking basis, and losses can face additional limits even when basis exists. IRS: stock and debt basis.

Keep payroll, distributions, capital contributions and shareholder loans separately identified. An owner transfer is not a substitute for deciding what the transaction represents. Accounting & Advisory can address the records and reconciliations within an agreed scope.

Payroll is an operating responsibility.

Employment-tax obligations can include federal income-tax withholding, employee and employer Social Security and Medicare taxes, and federal unemployment tax. Employers must deposit and report the relevant taxes and report employee compensation. Filing and deposit schedules are separate responsibilities; review the applicable forms, timing and any exceptions for the business. IRS: employment taxes and reporting.

Agree who handles payroll, who approves compensation and who reconciles payroll reports to the books. An election engagement or income-tax return does not automatically include payroll processing. Tax Preparation defines the returns CTAS will prepare rather than implying every filing is included.

Solo 401(k) planning starts with compensation and employees.

For an S-corporation employee, employee deferrals and employer retirement contributions are based on Form W-2 compensation, subject to the plan and applicable limits. S-corporation distributions are not retirement-plan compensation. Reducing wages can therefore affect contribution capacity as well as payroll tax. IRS: retirement contributions for S-corporation employees.

A one-participant, or Solo, 401(k) generally covers an owner with no employees, or the owner and spouse. Hiring employees who meet plan eligibility requirements changes the analysis: they must be included, and testing rules may apply unless an exemption applies. Employee deferral limits are generally per person across plans, not a fresh limit for each employer. Employer contributions and overall additions have their own limits. IRS: one-participant 401(k) plans.

Discuss employee eligibility, other retirement plans, the plan’s compensation definition and adoption, election, funding and reporting deadlines before setting a contribution target. Annual limits and catch-up rules change; this guide does not substitute a fixed dollar limit or an owner-specific calculation for that review.

Make the records support the planning.

Bring the current accounts, prior entity and owner returns, election records, payroll reports, owner-payment history and retirement-plan documents into the same conversation. Keep a description of the owner’s duties, time and compensation support alongside the numbers. Identify missing information before treating a projection as a decision.

For a law practice, discuss collections, operating expenses and any client-fund accounting responsibilities with the relevant professionals; a tax engagement is not a trust-account compliance opinion. Consultants may need to distinguish business cash flow from owner withdrawals. Healthcare and other practice owners should consider staff and benefit-plan facts alongside their own compensation. Established owner-operated companies may need to revisit the analysis as hiring, ownership or revenue changes.

Tax Planning connects the decision, assumptions and timing. Agree who implements any recommendation and whether accounting, payroll, legal or return work needs a separate engagement.

Common mistakes to address early.

• Electing S status without checking owners, effective dates, required consent and ongoing responsibilities.
• Using a fixed salary percentage or treating all owner payments as distributions.
• Confusing a K-1 allocation with cash received, or assuming every distribution is tax-free.
• Basing retirement contributions on distributions or overlooking eligible employees and other plans.
• Waiting until return preparation to explain unreconciled accounts or missing payroll records.

If an IRS notice has already arrived, the notice and its deadline require separate attention. IRS Representation concerns a defined, authorized matter; reading this guide or contacting CTAS does not extend an IRS deadline.

Consult before the election, payment or contribution.

Start with the decision ahead: an election, a change in owner duties or pay, a new employee, a distribution or a retirement contribution. Tell CTAS what is already in place and when a decision is needed. The first conversation establishes service fit and the work to consider; it is not a compensation determination or a savings guarantee.
