How to Form an S Corporation in Florida in 2026

Forming an S corporation in Florida is a two-step process: first, you form the underlying legal entity (either a Florida corporation under Chapter 607 or a Florida LLC under Chapter 605), and then you elect S corporation tax treatment by filing IRS Form 2553. The S corporation is not a separate entity type under Florida law - it is a federal tax classification that changes how the IRS taxes your business income.

This guide is for Tampa Bay and Florida business owners who want to understand what an S corporation actually is, whether they qualify, and how to make the election effectively. It covers the legal formation steps, IRS eligibility requirements, the 100-shareholder limit, the one-class-of-stock rule, and the reasonable compensation requirement that the IRS enforces against S-corp owners.

What Is an S Corporation?

An S corporation is a corporation or LLC that has elected to be taxed under Subchapter S of the Internal Revenue Code. Under this election, the business pays no federal income tax at the entity level. Instead, income and losses pass through to the shareholders' personal tax returns, similar to a partnership or sole proprietorship. This avoids the double taxation that C corporations face.

The key tax advantage: S-corp owners who work in the business pay themselves a reasonable salary (subject to employment taxes - FICA). Remaining profits are distributed as pass-through income not subject to self-employment tax (15.3%). For business owners with significant profits, this can mean savings of $10,000 or more per year.

S Corporation Eligibility Requirements

To elect S corporation status, your corporation or LLC must meet all of the following requirements at the time of election and on an ongoing basis:

1. Domestic Entity

The entity must be a domestic corporation or LLC - formed in the United States. Foreign entities do not qualify for S corporation election.

2. No More Than 100 Shareholders

An S corporation cannot have more than 100 shareholders. For counting purposes, members of the same family can elect to be treated as a single shareholder. This limit makes S corporations unsuitable for businesses that plan to raise capital from many investors.

3. Only Eligible Shareholders

All shareholders must be U.S. citizens or lawful permanent residents (resident aliens). The following cannot be S-corp shareholders: non-resident aliens, C corporations, other partnerships, and most trusts (except for certain grantor trusts, qualified subchapter S trusts, and electing small business trusts).

4. One Class of Stock

An S corporation can have only one class of stock. All shares must have identical rights to distribution and liquidation proceeds. Having two classes of stock (for example, common and preferred) automatically disqualifies the S election. This is the primary reason venture-backed companies cannot use S-corp status - VC deals require preferred stock.

5. Not an Ineligible Corporation

Certain types of corporations are categorically ineligible for S-corp election, including financial institutions using the reserve method of accounting for bad debts, insurance companies, and domestic international sales corporations (DISCs).

How to Form an S Corporation in Florida - Step by Step

Step 1 - Choose Your Entity Type: Corporation or LLC

You can elect S-corp status for either a Florida corporation or a Florida LLC. The choice affects governance, annual requirements, and future flexibility:

• Florida corporation: governed by Chapter 607, requires a board of directors, officers, bylaws, and annual meetings (or written consents in lieu of meeting). More formal governance structure.
• Florida LLC with S-corp election: governed by Chapter 605, more flexible governance, no mandatory board structure. The LLC remains an LLC under state law while being taxed as an S-corp federally.

Most small business owners choosing S-corp tax treatment today use an LLC as the underlying entity because of the governance flexibility. The S-corp tax treatment is identical regardless of whether the underlying entity is an LLC or a corporation.

Step 2 - Form the Entity with the Florida Division of Corporations

File the appropriate formation document at Sunbiz.org:

• For a Florida LLC: Articles of Organization, $125 filing fee
• For a Florida Corporation: Articles of Incorporation, $70 filing fee (plus $70 certified copy fee if you want a certified copy)

Standard processing takes 3 to 5 business days. Expedited options are available.

Step 3 - Obtain an EIN

Apply for an Employer Identification Number at IRS.gov. Free, immediate online. Required for S-corp tax filings and payroll.

Step 4 - File IRS Form 2553 (S-Corp Election)

Form 2553 is the "Election by a Small Business Corporation" - the document that formally elects S-corp treatment with the IRS. All shareholders must sign. Key timing rules:

• To elect S-corp status for the current tax year: file within 75 days of the beginning of the tax year, or within 75 days of the entity's formation if it is a new entity
• To elect S-corp status for the following tax year: file at any time during the current year

The IRS will send you a confirmation letter within 60 days. Keep this letter permanently - it is your evidence of S-corp election status.

Step 5 - Set Up Payroll

Once you have your S-corp election, you must pay yourself a reasonable W-2 salary if you actively work in the business. This requires a payroll system, quarterly payroll tax filings (Form 941), and year-end W-2 issuance. Payroll services cost approximately $50 to $150 per month for a single owner-employee.

Step 6 - File Form 1120-S Annually

The S corporation files Form 1120-S (U.S. Income Tax Return for an S Corporation) each year by March 15 (or September 15 with an extension). The return is informational - no entity-level tax is owed. The return generates a Schedule K-1 for each shareholder reporting their share of income, loss, and other items.

The Reasonable Compensation Requirement

The IRS's primary area of scrutiny with S corporations is the owner-employee salary. The self-employment tax savings come from taking some income as distributions rather than salary - but the salary must be "reasonable" for the services you actually provide to the business.

Factors the IRS examines when assessing reasonable compensation:

• What comparable employees performing similar services earn in your industry and market
• Your qualifications, experience, and responsibilities
• The time and effort you devote to the business
• The ratio of salary to total distributions - a very low salary relative to large distributions is a red flag

Setting your salary too low is the most common S-corp audit trigger. The IRS can recharacterize distributions as wages and assess back payroll taxes, penalties, and interest. Work with your CPA to document your salary decision with industry compensation data.

S-Corp Tax Savings: A Real Example

Here is how the math works for a Florida S-corp owner with $150,000 in net business income, compared to a standard LLC:

• Standard LLC (no S-corp): Self-employment tax on approximately $138,525 (92.35% x $150,000) = approximately $21,194 in SE tax
• S-corp with $75,000 salary: FICA on $75,000 salary = approximately $11,475 total (both sides). Zero SE tax on $75,000 distribution.
• Approximate annual savings: $9,719, minus payroll service costs (~$1,200-$1,800/year) = net savings of $7,900 to $8,500 per year

The savings scale with income. At $200,000 in net profits with an $85,000 salary, the savings can exceed $12,000 per year.
