An S corporation is a federal tax election, not a separate Florida entity type. For most Florida small-business owners, the practical route is to form a Florida LLC through Sunbiz and then file IRS Form 2553. For a calendar-year business, the common Form 2553 deadline is March 15.
You can also form a Florida corporation and elect S corporation status directly. The LLC route usually works well for owner-managed businesses because it combines Florida LLC liability protection with flexible management and S corporation tax treatment. A Florida corporation may be a better fit if you need a traditional stock structure or formal corporate governance.

Step 1: Choose a Florida LLC or Florida Corporation
Option 1: Form an LLC and Elect S Corporation Taxation
A Florida LLC can elect S corporation tax treatment for federal purposes by filing Form 2553. An eligible LLC generally does not need to file Form 8832 before making the S corporation election.
This structure is often used by:
- Freelancers and consultants
- Agencies and professional service businesses
- Online businesses
- Contractors
- Small retail or service companies
- Businesses with one or a few active owners
An LLC usually operates under an operating agreement instead of corporate bylaws. It can also have simpler internal administration.
Option 2: Form a Florida Profit Corporation and Elect S Status
A Florida profit corporation can elect S corporation treatment after incorporation. The corporation uses shares, directors, officers and corporate records.
A corporation may be a better fit if the business:
- Needs a formal stock structure
- Expects outside investors
- Plans to issue shares under a traditional corporate structure
- Has formal governance requirements
- May later change to C corporation taxation
An S corporation cannot have more than 100 shareholders. It generally cannot have partnerships, corporations or nonresident aliens as shareholders, and it may have only one class of stock.
The Important Limitation
S corporation status may not fit a business that expects venture capital investment, multiple economic classes of stock or ownership by ineligible entities. A C corporation may work better in those situations.
Step 2: Check and Reserve Your Business Name
Search the Florida Division of Corporations database before filing. The proposed name must be distinguishable from existing Florida business names.
A Florida LLC name must generally include "Limited Liability Company," "LLC" or "L.L.C." A Florida corporation name must generally include "Corporation," "Company," "Incorporated," "Corp.," "Co." or "Inc."
If the business will operate under a name that differs from its legal name, you may also need to register a Florida fictitious name, commonly called a DBA.
Step 3: Appoint a Florida Registered Agent
A registered agent receives lawsuits, official notices and other legal documents for the business.
The registered agent must:
- Have a physical street address in Florida
- Be available to receive service of process
- Sign the registered agent acceptance
- Keep the registered office information current
A post office box cannot be used as the registered office address. A business entity with an active Florida registration may serve as a registered agent, but the entity generally cannot serve as its own registered agent.
Step 4: File the Formation Document With Sunbiz
If You Are Forming an LLC
File Articles of Organization with the Florida Division of Corporations.
The required Florida filing fees are:
- Articles of Organization: $100
- Registered agent designation: $25
- Required formation total: $125
- Optional certified copy: $30
- Optional certificate of status: $5
The Florida Division of Corporations lists the full optional package total as $160.
If You Are Forming a Corporation
File Articles of Incorporation for a Florida profit corporation.
The required filing fees are:
- Articles of Incorporation: $35
- Registered agent designation: $35
- Required formation total: $70
- Optional certified copy: $8.75
- Optional certificate of status: $8.75
A Florida corporation must authorize at least one share. The Articles of Incorporation also identify the corporation's name, principal office, registered agent and incorporator.
After Sunbiz approves the filing, save the filed Articles, document number and certificate of status if you purchased one.
Step 5: Apply for an EIN
Apply for an Employer Identification Number, or EIN, with the IRS after the LLC or corporation has been legally formed.
Eligible applicants with a U.S. principal office can apply online. The EIN is used for federal tax filings, payroll, banking and other business transactions. The IRS recommends applying electronically when possible.
You will generally need:
- Legal business name
- Trade name, if different
- Principal business address
- Formation state
- Responsible party
- Business start date
- Business activity
- Expected number of employees
Do not apply for multiple EINs for the same entity.
Step 6: Create the Company's Internal Records
Set up the business as a separate legal and tax entity before it begins operating.
For an LLC, prepare an operating agreement that addresses:
- Ownership percentages
- Member contributions
- Management authority
- Profit and loss allocations
- Distributions
- Ownership transfers
- Procedures for adding or removing members
For a corporation, prepare corporate bylaws, appoint directors and officers, issue stock and record stock ownership in a capitalization ledger.
Every S corporation should also:
- Open a business bank account
- Keep business and personal spending separate
- Use written contracts
- Record owner contributions and distributions
- Maintain accounting records
- Approve major decisions in writing
Forming an entity without maintaining separate business records can weaken the practical value of the liability structure.
Step 7: File IRS Form 2553
File Form 2553, Election by a Small Business Corporation, with the IRS. All shareholders generally must sign the election. An LLC making the election signs as the eligible entity electing corporate treatment.
S Corporation Election Deadline
For a calendar-year business, Form 2553 is generally due no later than:
Two months and 15 days after the beginning of the tax year for which the election should apply.
For a business whose tax year begins January 1, the common deadline is March 15. If the deadline falls on a weekend or legal holiday, the next business day may apply.
The form asks for information such as:
- Entity name and EIN
- Effective date
- Tax year
- Shareholder information
- Ownership percentages
- Shareholder consent signatures
- Contact information
Keep the signed form and proof of filing with the company's permanent records.
What If Form 2553 Is Late?
The IRS may allow late-election relief when the business had reasonable cause, acted diligently after discovering the mistake and meets the other requirements in the Form 2553 instructions. The late-election procedure commonly references Revenue Procedure 2013-30.
Late-election relief is not automatic. Ask a tax professional to review the facts before filing.
Step 8: Put the Owner on Payroll
An owner who performs services for an S corporation is generally treated as a shareholder-employee. The S corporation must pay reasonable compensation before making non-wage distributions to that shareholder-employee.
Reasonable compensation depends on factors such as:
- The owner's duties
- Training and experience
- Time devoted to the company
- Comparable pay for similar work
- The company's gross receipts
- Payments made to other employees
- The source of the company's revenue
The company should run payroll, withhold applicable taxes and issue a Form W-2. Taking large distributions while paying an artificially low salary can lead the IRS to reclassify distributions as wages subject to employment taxes.
S corporation tax treatment does not eliminate payroll taxes. Any potential tax benefit generally comes from properly structured distributions made after reasonable compensation has been paid.
Step 9: Register for Florida Business Taxes That Apply
Florida has no personal income tax. Florida generally does not tax an individual shareholder's pass-through S corporation income through a personal income tax return.
The business may still need to register for Florida taxes.
Sales and Use Tax
If the business sells taxable goods or taxable services, register with the Florida Department of Revenue before conducting taxable sales. Florida uses the Business Tax Application, Form DR-1, for relevant registrations.
Reemployment Tax
If the business has employees, it may need to register for Florida reemployment tax. Florida employers, rather than employees, pay this tax.
Florida Corporate Income Tax
Most S corporation income passes through to shareholders for federal tax purposes, but Florida's rules still require review. The Florida Department of Revenue states that S corporations that pay federal income tax on line 23c of Form 1120-S must file a Florida corporate income tax return.
If a business was previously registered for Florida corporate income tax and later becomes an S corporation, it should notify the Florida Department of Revenue of the federal S election and its effective date.
Forming an S corporation does not eliminate every possible Florida tax filing.
Step 10: File Annual Reports and Tax Returns
Florida Annual Report
Every Florida LLC and corporation must file an annual report to remain active with the Division of Corporations. The annual report confirms or updates the company's public information. It is not a financial statement.
The filing period runs from January 1 through May 1. Failure to file can result in administrative dissolution.
Current annual report fees are:
- Florida LLC: $138.75
- Florida profit corporation: $150
- Late LLC annual report: $538.75
- Late corporation annual report: $550
Federal S Corporation Return
An S corporation generally files Form 1120-S each year and provides each shareholder with a Schedule K-1. A calendar-year S corporation generally files by March 15, subject to weekend, holiday and extension rules.
Shareholders report their allocated income, deductions and credits on their individual federal tax returns.
Do Florida S Corporations Have to File a BOI Report?
As of August 14, 2026, domestic U.S. companies are exempt from FinCEN beneficial ownership information reporting under FinCEN's final rule. Domestic Florida LLCs and corporations generally do not need to file a BOI report under the current rule.
Foreign entities registered to do business in the United States may still have reporting obligations.
Common Mistakes to Avoid
- Treating "S corp" as a Florida legal entity instead of a federal tax election
- Filing Form 2553 after the deadline without evaluating late-election relief
- Paying distributions instead of reasonable wages
- Mixing personal and business expenses
- Missing Florida's May 1 annual report deadline
- Failing to register for sales tax before taxable sales begin
- Assuming Florida's lack of personal income tax eliminates all business tax filings
- Issuing ownership interests that violate the S corporation one-class-of-stock rule
- Accepting an ineligible shareholder, such as a nonresident alien or another corporation
- Using an online filing service that charges for filings available directly through Sunbiz or the IRS
Recommended Setup for Most Florida Owner-Operated Businesses
For a typical Florida consulting, agency, contracting or professional service business, the usual process is:
- Form a Florida LLC through Sunbiz.
- Obtain an EIN from the IRS.
- Sign an operating agreement.
- Open a separate business bank account.
- File Form 2553 before the S corporation election deadline.
- Set up payroll for reasonable owner compensation.
- Register for sales tax or reemployment tax if applicable.
- File the Florida annual report by May 1.
- File Form 1120-S and issue Schedule K-1s each year.
A Florida CPA or tax attorney should review the election when the business has multiple owners, prior tax filings, foreign ownership, significant distributions, late-election issues or plans to raise outside capital.
