LLC vs S Corp in Florida: Tax Differences and How to Choose in 2026

One of the most common questions Florida business owners ask is: 'Should I have an LLC or an S corp?' The answer starts with understanding that these are not competing options - an S corp is a tax classification, not a type of entity. You can have an LLC and elect S-corp treatment at the same time. Many Tampa Bay business owners do exactly this to reduce self-employment taxes while keeping the simplicity of an LLC.

This guide explains how LLC default taxation and S-corp election taxation differ, when the election saves money, when it doesn't, and what the IRS requires if you make the switch.

What Is an S-Corp Election?

An S corporation is a federal tax classification recognized under Subchapter S of the Internal Revenue Code. When your LLC files IRS Form 2553 - "Election by a Small Business Corporation" - the IRS agrees to tax the LLC as an S corporation instead of its default treatment. The LLC remains an LLC under Florida law. Nothing changes with the Florida Division of Corporations. Only the federal tax treatment changes.

Under S-corp taxation, the LLC files Form 1120-S (an informational return), pays no entity-level federal income tax, and issues Schedule K-1s to members. The key difference from default LLC taxation is how self-employment tax is calculated.

Default LLC Taxation: Full Self-Employment Tax

When a Florida LLC is taxed as a disregarded entity (single-member) or partnership (multi-member) by default, the active members who work in the business owe self-employment tax on all net business income. Self-employment tax is 15.3% on net income up to the Social Security wage base ($168,600 in 2024, adjusted annually), and 2.9% on income above that threshold.

Example: $140,000 in net LLC income.

• SE tax base: 92.35% x $140,000 = $129,290
• SE tax: 15.3% x $129,290 = approximately $19,781
• Federal income tax: separate, on top of the SE tax
• Florida state income tax: $0 (no personal income tax)

That $19,781 in SE tax is paid before you calculate income tax. For a full-time business owner, it is one of the largest annual tax bills.

S-Corp Election: Splitting Income Into Salary and Distributions

With an S-corp election, the LLC owner splits income into two buckets: a W-2 salary and pass-through distributions. Only the salary is subject to FICA taxes (the corporate version of SE tax). Distributions are subject to income tax but not FICA/SE tax.

Same example: $140,000 in net LLC income, S-corp election, $70,000 reasonable salary.

• FICA on $70,000 salary: approximately $10,710 (employer and employee share combined)
• SE tax on $70,000 distribution: $0
• Annual SE/FICA tax savings: approximately $9,071
• Florida state income tax: $0 (no personal income tax - full savings stays with you)

The Reasonable Compensation Requirement

The IRS allows the S-corp election but requires that owner-employees who perform services for the company pay themselves a 'reasonable' W-2 salary before taking distributions. Setting the salary unreasonably low to maximize distributions is an IRS audit trigger.

Factors the IRS considers in determining reasonable compensation: what comparable employees in your industry earn for similar roles, your time commitment, the complexity of your work, and the historical wages paid for the position. There is no exact formula - the analysis is fact-specific.

• Document your compensation decision in writing - a memo or compensation study helps in an audit
• Research Bureau of Labor Statistics salary data for comparable roles in Florida
• Review court and IRS guidance on comparable S-corp cases in your industry
• Work with a CPA who is experienced with S-corp reasonable compensation analysis

When the S-Corp Election Makes Sense

The S-corp election generally produces positive ROI when:

• Net LLC income consistently exceeds $50,000-$60,000 per year
• You actively work in the business (as opposed to passive investors)
• All members are U.S. citizens or residents
• There is only one class of economic interest (no preferred vs. common membership interests)
• The LLC has 100 or fewer members
• The SE tax savings outweigh the additional cost of running payroll and filing Form 1120-S

When the S-Corp Election Does NOT Make Sense

• Income below $50,000: Payroll service costs ($50-$150/month) and additional CPA fees for Form 1120-S may equal or exceed the SE tax savings at lower income levels.
• Passive income (e.g., rental income): Rental income is generally not subject to SE tax even without the S-corp election. The election provides no SE tax savings on passive income.
• Businesses planning to raise VC capital: S-corps cannot have more than 100 shareholders, cannot have foreign owners, and cannot issue preferred stock. If you plan to raise institutional capital, a C-corp structure is required.
• LLCs with foreign members: Non-resident alien members disqualify the LLC from S-corp election.
• LLCs with multiple classes of membership interest: S-corps can only have one class of stock (or equivalent economic interest). Preferred returns, special allocations, or profit interest holders may disqualify the election.

How to Make the S-Corp Election for Your Florida LLC

• File IRS Form 2553: The election must be filed within 75 days of the tax year for which you want the election to be effective, or at any time during the prior tax year. Late elections may be available with IRS permission.
• Set up payroll: You must pay yourself a W-2 salary from the date the election takes effect. Use a payroll service or have your accountant set this up before the first paycheck.
• File Form 1120-S annually: Due March 15 each year (extendable to September 15). The return is informational - no entity-level tax is owed.
• File quarterly payroll tax returns (Form 941): Report wages, withholding, and FICA deposits quarterly.

Your LLC remains an LLC under Florida law - no changes to your Articles of Organization or operating agreement are required unless your operating agreement has provisions that conflict with S-corp requirements.
