How to Apply for an EIN in Florida

The EIN step itself

One federal form, one agency, the same options wherever the business sits: online, fax, mail, or the international phone line. The method decides the timeline, not the state. Every method and what it actually takes covers that in full, and it applies to Florida unchanged.

What Florida needs first

Form your entity with the Florida Division of Corporations (Sunbiz) before applying. The IRS asks for the legal name and formation date exactly as the state recorded them, and a mismatch is one of the common causes of a rejected application.

Florida issues a document number — they look like L26000449593. It identifies your company in state records and is not a tax ID. It cannot be used where an EIN is asked for, and the IRS has no record of it.

What Florida requires once you have the EIN

• Register with the Florida Department of Revenue if you will collect sales tax or pay wages — the EIN is required on that registration.
• File your first Florida annual report with the Division of Corporations in the calendar year after formation, and every year after.

What is actually different about Florida

• Florida LLC document numbers begin with the letter L followed by the filing year — an LLC formed in 2026 carries an L26 prefix. That is the number Sunbiz indexes your company by, and it is not your EIN.
• Florida has no personal state income tax, so the tax classification you choose on the SS-4 only affects your federal return. In most states it drives a state filing too.
• Sunbiz publishes new filings publicly and almost immediately, which is why Florida LLC owners typically start receiving mail and texts about EINs within days of forming.
