Converting a Florida business from one entity type to another — sole proprietor to LLC, LLC to S-corp, S-corp to C-corp — has significant federal and state tax consequences that must be analyzed before the conversion. Some conversions are tax-free; others trigger immediate taxable events. This guide covers the most common Florida business entity conversion scenarios and their tax implications.
Tax impact: none — a single-member LLC is a disregarded entity by default, treated identically to a sole proprietor for federal tax purposes. Schedule C filing continues unchanged. No asset transfer tax. No election required. State impact: Florida requires filing Articles of Organization (sunbiz.org, $100 filing fee) and paying annual report fees ($138.75). For liability protection purposes, converting to an LLC is low-risk and commonly done. Tax considerations: future elections (S-corp, etc.) start from the LLC's date of formation.

An existing LLC can elect S-corp taxation by filing Form 2553. This is an election change, not a structural conversion — the LLC entity remains; only the tax treatment changes. No asset transfer; no gain recognized. Effective date: the election takes effect for the tax year specified in Form 2553 (must be filed by March 15 of the target year or within 75 days of the tax year beginning). Florida impact: no separate state S-corp election; Florida does not tax S-corp income at the individual level. Must establish payroll immediately upon S-corp election.
An existing C-corp can elect S-corp status by filing Form 2553 if it meets S-corp eligibility requirements (100 or fewer shareholders, single class of stock, no foreign shareholders). Tax consequences: built-in gains tax (BIG) applies for 5 years after conversion — gains on assets that appreciated while the C-corp is subject to C-corp tax rate when sold within 5 years of the conversion. Retained earnings (E&P) from C-corp years must be distributed as dividends (taxed to shareholders) or remain in the company (tracked separately from S-corp earnings). Complex — requires a CPA.
Revoking an S-corp election (reverting to C-corp taxation) is rare for Florida small businesses but occurs when seeking venture capital or preparing for IPO. Revocation requires consent of more than 50% of shareholders. After revocation, the entity is taxed as a C-corp — subject to 21% federal corporate tax + 5.5% Florida corporate income tax on retained earnings. If re-electing S-corp status in the future, the IRS requires a 5-year waiting period after the prior S-corp termination (with exceptions). C-corp status requires formal quarterly meetings, board approvals, and more rigorous corporate governance.
Converting a general partnership to an LLC in Florida is generally tax-free — treated as a continuation of the existing business. Converting a partnership to a corporation triggers a taxable event if appreciated assets are transferred — the IRS treats this as a distribution of assets to partners followed by a contribution to the corporation, potentially triggering gain recognition. Consult a tax attorney before converting any partnership with appreciated assets to a corporate structure. The partnership → S-corp conversion requires meeting S-corp eligibility; if the partnership has more than 100 partners, it cannot become an S-corp.
