Katz & Associates / Choosing a business structure
An LLC and an S corporation are not two versions of the same choice. Start with owners, control, and risk. Then check how tax rules apply.
Do not choose by acronym alone
The legal form of a business helps set who owns it, who can run it, and who may owe its debts. Its federal tax status is a separate question. An LLC may be taxed in more than one way. The owners and any tax election matter.
There is no single best structure for every Florida business. Compare your actual owners, plans, contracts, and risks with business formation counsel and a qualified tax adviser before filing.
A two-axis planning map
This map gives common examples. It is not an eligibility test or a recommendation to make an election.
| State-law starting point | Federal income-tax question |
|---|---|
| Domestic LLC with one owner | Generally disregarded as separate from its owner for income tax unless corporate treatment is elected. Other taxes can treat it separately. |
| Domestic LLC with two or more owners | Generally treated as a partnership unless it elects corporate treatment. |
| Eligible LLC or corporation | Can it meet the S corporation rules, make the election, and keep that status? |
| Corporation | What corporate tax rules apply, and is an S election available and appropriate? |
Sources: IRS guidance on LLC classifications and S corporations. Defaults, eligibility, and elections require individual review.
Who owns it now and later?
List who will own the business and what each person contributes. Separate cash, property, services, and promises of future work. Discuss whether ownership changes if a promised contribution never arrives.
Then identify how decisions will be made. Who manages daily work? Which decisions need all owners or a specified vote? What happens if two equal owners disagree? The filing alone may not answer these practical questions.
Future investors can affect the choice. What rights might they want? Will they need different terms for profits or payments? Check whether the planned owners fit the tax election’s limits.
Exit planning matters from the start. Can an owner sell to anyone? What happens after death, incapacity, retirement, or a serious dispute? Business succession planning can help coordinate those terms with a personal estate plan.
Limited liability is not no liability
Florida’s LLC liability statute provides that members and managers are not personally liable for company obligations solely because of that role. It does not make every personal obligation or act immune from liability.
If you sign a personal guarantee, for example, review that promise separately. Ask who is bound by each lease, loan, or contract and in what capacity. Forming an entity does not make an already personal promise disappear.
Do not treat all partnerships alike. §620.8306 distinguishes general partner liability from obligations incurred while a partnership is a limited liability partnership. The entity form and the facts matter.
Keep records, accounts, and signing authority clear. These steps help you track what the business owes. Do not assume any missed LLC formality makes an owner liable. Section 605.0304 expressly addresses that issue.
Review the signature line. The name on the contract, your title, and any guarantee can matter as much as the entity’s name on Sunbiz. Our business contract review guide explains what to check before signing.
An election brings rules and work
S status is a federal tax choice for an entity that meets the rules. It is not a separate Florida legal form that answers every business question.
The IRS restricts eligible owners and other features. Certain trusts and estates may qualify as shareholders; partnerships, corporations, and nonresident alien shareholders generally may not. Other requirements include limits on shareholder count and stock classes. Review the full rules, not just one condition.
For an LLC, count the owners and check any election. Both affect its federal income tax. “Disregarded” does not mean the LLC has no separate legal existence or that every tax treats it the same way.
Ask a tax adviser to compare the facts. What income do you expect? How will owners be paid? What returns and other work will be needed? Do not choose from a generic promised savings percentage. An election that fits now may need review when an owner joins or leaves.
Choose with the operating facts in view
Who owns what? Who controls decisions? Who may sign? What personal obligations are expected? Which investors might join? What happens if an owner leaves?
Bring the proposed name, activity, owners, locations, and any draft contracts or financing terms. Tell advisers about regulated work or professional licensing needs. What suits one business may not fit another.
Ask what must happen after formation: governing agreements, tax elections, accounts, licenses, insurance, records, and recurring filings. Our startup planning guide helps separate formation from the other commitments that come before operations.
If the business already exists, do not just change its label. Review contracts, taxes, licenses, assets, and required owner consent. The change may reach well beyond the form you are about to file.
Make the choices together
Discuss formation, control, contracts, and future ownership changes with Katz & Associates, and coordinate tax treatment with your tax adviser.
Common questions
No. The default depends on the number of owners, and elections can change the federal tax treatment. A single-owner LLC generally has a different default income-tax classification.
Do not assume so. A guarantee is a separate personal promise that needs review. Limited liability based on entity status does not erase every obligation you take on yourself.
Changes may be possible. First review the effects on taxes, contracts, licenses, and owners’ rights. Do not assume the change is only a new form or name.
