For most small Florida businesses with a handful of US owners who take the profits out each year, an S-Corp comes out ahead. A C-Corp makes more sense if you plan to raise venture capital, have foreign or corporate investors, or want to keep most of your profit inside the company. That’s the short version of S-Corp vs C-Corp in Florida. The rest of this page covers the details that decide it.
One thing to clear up first: an S-Corp isn’t a different kind of company. Both start as the same Florida corporation. The difference is how the IRS taxes it.
How are S-Corps and C-Corps different?
When you file Articles of Incorporation with the Florida Division of Corporations on Sunbiz, you get a C-Corp by default. It pays its own corporate income tax, and shareholders pay tax again on any dividends. That’s the “double taxation” everyone talks about.
An S-Corp is that same corporation after it files Form 2553 with the IRS. The corporation stops paying federal income tax. Profits pass through to the shareholders’ personal returns instead, and they pay tax at their own rates. Both structures give you the same limited liability protection.
| Feature | S-Corp | C-Corp |
|---|---|---|
| How you form it | File Articles with Sunbiz, then elect with the IRS | File Articles with Sunbiz |
| Federal tax | Passes through to shareholders | 21% corporate tax, plus tax on dividends |
| Florida tax | No state corporate or personal tax | 5.5% corporate income tax |
| Double taxation | No | Yes |
| Self-employment tax | Possible savings on distributions | Doesn’t apply to dividends |
| Shareholder limit | 100 | Unlimited |
| Who can own shares | US citizens, permanent residents, certain trusts and estates | Any person or entity |
| Stock classes | One (voting differences allowed) | Multiple |
| Foreign owners | Not allowed | Allowed |
| Venture capital | Generally not suitable | The standard structure |
| Florida annual report | $150, due by May 1 | $150, due by May 1 |
| Fringe benefits | Limited deductibility for over-2% shareholders | Fully deductible for all |
How do you form each one in Florida?
The Florida side is identical. You file Articles of Incorporation on Sunbiz, with a corporate name ending in “Corporation,” “Corp.,” “Incorporated” or “Inc.,” a principal address, a registered agent with a Florida street address, the number of authorized shares, and incorporator details. The state filing fee is $70.
After that, get a free EIN from the IRS online, adopt bylaws (Florida doesn’t need a copy), hold an organizational meeting to elect officers and authorize shares, and issue stock to your initial shareholders.
The S-Corp takes one more step. You file Form 2553 with the IRS within 2 months and 15 days of the start of the tax year you want it to cover. For a new corporation, that clock starts when the corporation is formed. For an existing calendar-year corporation, the deadline is March 15. Every shareholder has to sign. Miss the deadline and you’re taxed as a C-Corp for that year.
How is each one taxed in Florida?
Florida has no personal income tax. That works in the S-Corp’s favor: pass-through profits pay federal tax and nothing to the state. A C-Corp, by contrast, pays Florida’s 5.5% corporate income tax on top of the 21% federal rate.
For a C-Corp, dividends are taxed federally at 0%, 15% or 20% depending on the shareholder’s income. Florida doesn’t tax them. For an S-Corp, shareholders pay federal income tax on their share of the profit at ordinary rates (10% to 37%). The S-Corp can also cut self-employment tax, because owners who work in the business pay payroll taxes on a reasonable salary but not on distributions above it.
What does that look like on $200,000 of profit?
Here’s a simplified comparison for a Florida corporation earning $200,000.
| Step | C-Corp | S-Corp |
|---|---|---|
| Federal corporate tax (21%) | $42,000 | $0 |
| Florida corporate tax (5.5%) | $11,000 | $0 |
| Profit left after corporate tax | $147,000 | $200,000 |
| Shareholder tax | $22,050 (15% on dividends) | $48,000 (single owner in the 24% bracket) |
| Florida personal tax | $0 | $0 |
| Total | $75,050 (37.5%) | About $48,000 (24%) |
The S-Corp figure leaves out payroll taxes on the owner’s salary, and real returns won’t apply one bracket to every dollar. Still, the gap is wide enough that the S-Corp wins in most cases like this one. Your own numbers depend on profit, salary and how much you distribute, so run them with a CPA.
When does C-Corp tax treatment win?
When you keep the money in the business. If you’re reinvesting most of the profit, the C-Corp pays 21% federal now and shareholders pay nothing until dividends go out. Compare that with an S-Corp owner in the 37% bracket paying tax on profit they never took home. C-Corps also handle fringe benefits better: health insurance and similar perks are fully deductible for every shareholder-employee.
Who can own an S-Corp?
This is where many businesses get ruled out. The IRS limits S-Corps to:
- 100 shareholders at most (family members can elect to count as one)
- Shareholders who are US citizens, permanent residents, certain trusts or estates
- No corporations or partnerships as shareholders
- One class of stock (different voting rights are fine)
- Unanimous shareholder consent to the election
A C-Corp has none of these limits. It can have any number of shareholders of any type, including foreign individuals and other companies, and it can issue preferred and common stock. That’s why investors almost always require one.
If an S-Corp breaks any of these rules, say by taking on a 101st shareholder or a foreign owner, the election ends automatically and the company becomes a C-Corp. Watch your cap table if you’re anywhere near the limits.
What does each cost to run?
The state costs are the same for both:
| Cost | S-Corp | C-Corp |
|---|---|---|
| Articles of Incorporation | $70 | $70 |
| Registered agent service (optional) | $100-$300 a year | $100-$300 a year |
| Attorney for formation (optional) | $500-$2,000 | $500-$2,000 |
| Florida annual report | $150 | $150 |
| Federal tax return preparation | $500-$2,000+ | $800-$3,000+ |
| Bookkeeping and accounting | $1,000-$5,000+ a year | $1,000-$5,000+ a year |
The annual report is due by May 1, with a $400 late fee after that. You also need to keep a registered agent at a Florida street address and keep your bylaws, meeting minutes, stock records and financial records.
Federally, an S-Corp files Form 1120-S, sends each shareholder a Schedule K-1, and has to pay shareholder-employees a reasonable salary. A C-Corp files Form 1120 and issues 1099-DIV forms for dividends.
The admin costs barely differ. Taxes are where the real money is.
Which should you choose?
We’d pick an S-Corp if you’re a professional practice, consultant, service business or family company with steady profits, a small group of US owners and no plans to bring in investors. You avoid double taxation, Florida doesn’t tax your share, and the salary-plus-distributions setup can lower self-employment tax.
Pick a C-Corp if you’re raising venture or angel money, might go public, have foreign owners, need preferred stock, plan to offer stock options, or will reinvest most of your earnings. VCs nearly always require a C-Corp, so if that’s your path, start there.
If you can’t tell yet, think about where the business will be in 3 to 5 years. Switching from S to C is easy. Switching from C to S can trigger built-in gains tax on assets that have gone up in value.
Can you switch later?
Yes, in either direction.
To go from C-Corp to S-Corp, you file Form 2553 with unanimous shareholder consent and meet every eligibility rule. The election takes effect at the start of the next tax year, or the current year if you file in time. Be ready for possible built-in gains tax on appreciated assets.
To go from S-Corp to C-Corp, shareholders holding more than 50% of the shares sign a written revocation and file it with the IRS. The catch is that you generally can’t re-elect S-Corp status for five years without IRS permission.
When should you get professional help?
Talk to a Florida business attorney and a CPA before you file if you’re taking outside investment, have foreign shareholders, own assets that have grown in value, or plan to offer meaningful fringe benefits. These cases are where a wrong choice costs real money, and the fix (a conversion) can cost more.
Frequently asked questions
Can I start as an S-Corp and later become a C-Corp?
Yes. Shareholders owning more than 50% of the shares can revoke the election at any time, and it usually takes effect the following tax year. After that, you generally can’t go back to S-Corp status for five years without IRS approval.
Do I register an S-Corp separately with Florida?
No. S-Corp status is only a federal tax election. Florida treats S-Corps and C-Corps as the same kind of corporation.
Can a single-member LLC elect S-Corp status in Florida?
Yes. A single-member LLC can file Form 2553 to be taxed as an S-Corp. You keep the simpler LLC structure and may save on self-employment tax.
What’s a “reasonable salary” for an S-Corp owner?
Roughly what you’d have to pay someone else to do your job. The IRS requires shareholder-employees to take a reasonable salary before taking distributions, and it looks hard at salaries set artificially low to dodge payroll taxes.
Which industries suit each structure?
Professional services like consulting, medical and legal practices often do well as S-Corps because their income is steady and they distribute most of it. Tech startups raising venture money almost always choose C-Corps because investors require it. Real estate can work either way. S-Corps can suit rental holdings, while a C-Corp may suit a fix-and-flip business that reinvests profits quickly.
Can I deduct health insurance with an S-Corp?
Yes, but differently. For shareholders who own more than 2%, the premiums go into their W-2 wages and are deducted on their personal Form 1040, not on the corporate return. In a C-Corp, health insurance is a fully deductible corporate expense and isn’t added to the shareholder’s taxable wages.
Do Florida’s annual report rules differ between S-Corps and C-Corps?
No. Both file by May 1, pay the same $150 fee and report the same information.
Ready to form your Florida corporation?
Whichever tax status you choose, it starts with Articles of Incorporation on Sunbiz. If S-Corp is your plan, put the Form 2553 deadline in your calendar the day your corporation is approved. It’s an easy step to miss, and missing it costs you a full year of S-Corp treatment.
