Florida doesn’t have a personal income tax, which is great for sole proprietors and pass-through entities. But that doesn’t mean you have no filing requirements. Federal returns are still mandatory, and certain businesses owe Florida corporate income tax.

Sole proprietors report business income on Schedule C, which attaches to your personal Form 1040. You’ll also file Schedule SE for self-employment tax if your net earnings exceed $400. Florida requires no additional state income tax forms for sole proprietors.

Single-member LLCs follow the same process as sole proprietors unless you’ve elected corporate taxation. The IRS treats them as disregarded entities, so your business income flows to your personal return through Schedule C.

Partnerships and multi-member LLCs file Form 1065 with the IRS. This is an informational return that reports the partnership’s income and expenses. Each partner receives a Schedule K-1 showing their share of income, which they report on their personal returns. Florida doesn’t require a separate partnership return.

S corporations file Form 1120-S with the IRS. Like partnerships, income passes through to shareholders via Schedule K-1. Florida does not tax S corporation income at the entity level, so there’s no state corporate return for S corps.

C corporations have the most filing requirements. You’ll file Form 1120 with the IRS for federal corporate income tax. Florida also imposes a corporate income tax on C corporations, requiring Form F-1120 if your federal taxable income exceeds $50,000. The Florida rate is 5.5% on income above that threshold.

Sales tax adds another layer if you sell taxable goods or services. You’ll register with the Florida Department of Revenue and file returns monthly, quarterly, or annually depending on your volume. A Boca Raton fractional CFO can help determine your filing frequency and ensure you’re collecting the correct rates for each jurisdiction.

The Florida Annual Report is required for all corporations, LLCs, and limited partnerships registered with the state. This isn’t a tax form, but it’s due every year by May 1st and carries a $400 late fee if missed. File through the Florida Division of Corporations website.

Payroll creates additional requirements if you have employees. You’ll file Form 941 quarterly with the IRS for federal payroll taxes, plus Form 940 annually for federal unemployment tax. Florida requires quarterly RT-6 filings for state unemployment tax.

Getting the forms right matters less than getting the numbers right. The forms themselves are straightforward once you have accurate financial records. Working with a firm that handles business tax returns ensures the underlying accounting supports what you’re filing and that you’re not missing deductions or making errors that trigger notices.
