Introduction
Adding an Employer Identification Number (EIN) to your Florida LLC means applying for a 9-digit tax ID from the IRS. You can apply online at irs.gov for free and get your EIN the same day. Here's what you need to know before you start.
What is an EIN and what does it do for your Florida LLC?
An EIN is a 9-digit number the IRS assigns to your business — think of it as a Social Security number for your LLC. The IRS uses it to identify your business for federal tax purposes. Your Florida LLC uses it on tax returns, payroll filings, and bank account applications.
Most Florida LLC owners need an EIN for at least one of these reasons before they realize it. Here's where it comes up in practice:
- Hiring employees — you need an EIN to set up payroll and withhold payroll taxes
- Opening a business bank account — banks require an EIN to confirm the account belongs to the business, not you personally
- Building business credit — lenders use your EIN to evaluate your LLC's credit history separately from your personal credit
- Filing federal and state taxes — your EIN goes on every tax return and IRS document your LLC files
- Buying inventory for resale — your EIN can serve as proof of business status, which may exempt you from paying sales tax on goods you intend to resell
Does your Florida LLC need an EIN?
It depends on your situation, but most Florida LLCs need one. The IRS requires an EIN if your LLC has more than 1 member, has employees, or is taxed as a corporation. Single-member LLCs with no employees can use the owner's Social Security number instead — but getting an EIN is still worth doing.
Using your Social Security number on business documents puts your personal number in front of vendors, banks, and clients. An EIN keeps your personal number off those records. For a free application that takes under 15 minutes online, that's an easy trade-off to make.
How to apply for an EIN for your Florida LLC
You apply for an EIN directly through the IRS using Form SS-4. The IRS offers 4 ways to file: online, by fax, by mail, or by phone (for international applicants). Online is the fastest — you get your EIN immediately after completing the application.
Apply online (recommended)
Go to irs.gov/ein and complete the online application. The IRS online EIN application is available Monday through Friday, 7 AM – 10 PM ET. You'll answer questions about your LLC's structure, ownership, and reason for applying. At the end, the IRS issues your EIN immediately — you can download and save the confirmation notice right away.
Apply by fax
Download Form SS-4 from irs.gov, complete it, and fax it to the IRS. Fax applications for Florida businesses go to the IRS campus that handles your state. Processing takes about 4 business days, and the IRS faxes your EIN back to you.
Apply by mail
Mail a completed Form SS-4 to the IRS. Mail applications take about 4 weeks to process. Use this method only if you have no time-sensitive need for your EIN — the online application is faster and free.
Before you start, have your Florida LLC's formation documents ready. You'll need your LLC's legal name, the date it was formed, the state of formation (Florida), and the name and Social Security number of the responsible party — typically the owner or a managing member.
How much does an EIN cost in Florida?
Getting an EIN directly from the IRS is free. There's no state fee and no federal fee — the IRS does not charge for EIN applications regardless of how you file. The only cost is your time, which is under 15 minutes if you apply online.
If you'd rather have someone handle it for you, we offer EIN filing as part of our formation packages. That's worth considering if you're forming your LLC and want everything — formation documents, registered agent, and EIN — handled in one place.
How long does it take to get an EIN in Florida?
Online applications are processed immediately — you get your EIN the same day, as soon as you finish the form. Fax applications take about 4 business days. Mail applications take about 4 weeks. The method you choose is the biggest factor in how fast you get your number.
One thing to keep in mind: the IRS online application is only available Monday through Friday, 7 AM – 10 PM ET. If you try to apply outside those hours, you'll need to come back during the window or use the fax method instead.
Should you add your EIN to Sunbiz?
Florida does not require you to add your EIN to your Sunbiz (Florida Division of Corporations) record. Your EIN is a federal tax ID issued by the IRS — it's separate from your state registration. Sunbiz tracks your LLC's state-level information, not your federal tax ID.
That said, some business owners choose to update their Sunbiz record with their FEIN (Federal Employer Identification Number) for their own recordkeeping. If you want to do that, you can file an amendment through Sunbiz at dos.fl.gov. Keep in mind that information filed with Sunbiz becomes part of the public record — your EIN will be visible to anyone who searches your business. Most Florida LLC owners skip this step and keep their EIN on file privately.
FAQ
It depends. Florida LLCs with more than 1 member, employees, or a corporate tax election are required to have an EIN. Single-member LLCs with no employees can use the owner's Social Security number instead. Even so, getting an EIN is worth doing — it keeps your personal Social Security number off business documents and is required to open most business bank accounts.

The IRS online application is available Monday through Friday, 7 AM – 10 PM ET. You can also apply by fax (about 4 business days) or by mail (about 4 weeks). There's no state fee and no federal fee.
Getting an EIN from the IRS is free. There's no state fee and no federal application fee. The IRS does not charge for EIN applications regardless of whether you apply online, by fax, or by mail. If you'd prefer to have a formation platform handle the filing for you, that service typically comes with a fee.
It depends on the situation. If you previously had a sole proprietorship and formed an LLC, the IRS generally requires a new EIN for the LLC — the two are separate legal entities for tax purposes. If you already have an EIN assigned to your LLC from a prior registration, you don't need a new one. Talk to a tax professional if you're unsure whether your existing EIN carries over to your current LLC structure.
No, not unless you have a specific reason to. Florida does not require you to add your EIN to your Sunbiz record. Your EIN is a federal tax ID — it's separate from your state registration. If you do add it, that information becomes part of the public record. Most Florida LLC owners keep their EIN on file privately and don't include it in their Sunbiz filing.
Yes, a FEIN (Federal Employer Identification Number) and an EIN (Employer Identification Number) are the same thing. Both terms refer to the 9-digit number the IRS assigns to your business. You'll see both abbreviations used on state forms, bank applications, and IRS documents — they mean the same number.
