How To Get A Florida EIN For LLCs (Mar. 2026)

Forming a Florida Limited Liability Company (LLC) provides numerous tax and business advantages. However, you cannot begin full business operations without an Employer Identification Number (EIN).

This is a federal tax ID issued by the Internal Revenue Service (IRS) that’s used to open a dedicated business bank account, hire employees, file federal taxes, and complete payroll.

While the IRS issues your EIN and not the state, all Florida LLCs must obtain one to complete their state-level taxes, occupational business licenses, local licensing procedures, and many banking procedures. Your LLC is unable to operate in any meaningful way without an EIN.

In this guide, I’ve explained why you need a Florida EIN for your LLC, how to get one, and what to do once approved to stay compliant.

What Is A Florida EIN?

An EIN is a unique 9-digit federal identifier used by the IRS to identify your LLC for regulatory and tax compliance. It functions as your taxpayer identification number for the IRS and most financial institutions.

You must obtain an EIN to complete several core operations and financial tasks. These include:

• Opening a dedicated business bank account.
• Hiring employees and running payroll.
• Obtaining business financing and credit cards.
• Paying your excise and sales taxes.
• Building a business credit profile.

The table below lists the different EIN terms commonly used. I recommend reviewing them carefully to avoid confusion when applying for your EIN.

2. Do I Need An EIN For An LLC In Florida?

Your Florida LLC is faxed by the IRS, depending on its member numbers (by default) or by election, with the state applying the same treatment.

• Single-member LLCs: Taxed as a sole proprietorship (By default).
• Multi-member LLCs: Taxed as a partnership (By default).

a. Multi-Member LLC

Regardless of your tax election, your LLC must still have an EIN. This is required under the Code of Federal Regulations (C.F.R.) § 301.6109-1(a)(1)(ii-C).

Your EIN is the only number used by the IRS to identify your LLC. Without one, they have no way to track your tax obligations, process your filings, and treat you as a separate legal taxpayer.

b. Single-Member LLC

If you’re a single-member LLC and elect to be taxed as a corporation (S-Corp or C-Corp), obtaining an EIN is mandatory for the same reason as multi-member LLCs.

I strongly recommend you obtain an EIN regardless of your mandatory requirements because the exemption classes are extremely narrow. Once your business starts to become operational, getting an EIN is a mandatory IRS requirement if you want to lawfully operate your single-member LLC.

How Much Does A Florida EIN Cost

If you use the official IRS website, obtaining your EIN is completely free.

If you file by mail, you may need to pay a small filing fee to the postal service. Furthermore, unofficial EIN application websites often impose a small application charge.

When Should I Get An EIN For My LLC?

While I advise you to complete your business filings ahead of time, don’t apply for your EIN until your Articles of Organization have been officially approved by Sunbiz.

According to the IRS requirements, you must have formed a “separate legal entity” before your EIN application can be processed.

Under the Florida Statutes § 605.0201(4), your Florida LLC only becomes effective once your Articles of Organization have been accepted by the state.

Once approved, your chosen LLC name (Stated in your Articles of Organization) must be an exact match with the LLC name stated on your EIN Confirmation Letter.

Your EIN information can be mismatched with your formation documents if you apply too early, leading to your application being amended or rejected. This can potentially delay your banking and tax registrations.

How To Get An EIN In Florida: A Step-By-Step Guide

You can acquire your EIN using three main IRS filing methods. The correct one to use depends on your desired processing time and residency status.

1. Online applications (Must have an SSN or ITIN).
2. Mail applications.
3. Fax applications.

1. IRS Online Application (U.S. Citizens And U.S. Residents)

You should use the online EIN filing portal if you’re a U.S. resident with an SSN or ITIN.

• The online process typically takes approximately 10–15 minutes.
• Applications are processed instantly. Your EIN is issued immediately after submission.

2. IRS Mail And Fax Applications (Non-U.S. Residents)

You must apply for your EIN by mail or by fax if you’re a non-U.S. resident without an SSN or ITIN. You can NOT use the online filing system in this case.

• Complete and submit Form SS-4 by mail or fax to the IRS.
• Applications take approximately 4 business days by fax and 4–6 weeks by mail. This is much longer than the online filing method.

You can read my article on Getting An EIN Without An SSN Or ITIN if you need detailed filing instructions.

Getting Your EIN Approval (EIN Confirmation Letter)

Once approved, the IRS will send you an official confirmation letter with your EIN.

1. How You Will Receive Your EIN Confirmation Letter

You’ll receive an EIN Confirmation Letter (Form CP-575) from the IRS once your EIN application has been approved.

This is the official proof that your LLC has been assigned a Federal EIN for tax and employment obligations.

• Your CP-575 Form is available to download immediately if you apply online.
• You’ll receive your EIN Confirmation Letter by mail if you use the fax or mail application methods.

2. How Can You Find Your EIN Online

The IRS will NOT provide a duplicate copy if you lose your EIN Confirmation Letter (CP-575) or fail to download it after applying online. If this happens, you need to request an EIN Verification Letter (Form 147C) to officially replace it.

• Contact the IRS directly at 800-829-4933 (Monday to Friday, 7 A.M. to 7 P.M ET).
• The IRS can provide your EIN over the phone after you’ve verified your identity and business authorization.

Why You Need An EIN For Your Florida LLC

This means that penalties do NOT stem from a single code mandating all LLCs to have an EIN. Rather, they come from the requirement to use an EIN for regulatory forms, when making payments, and complying with reporting requirements.

You have three major reasons why you must get an EIN for your Florida LLC:

1. Complying With State Requirements

Your EIN acts as your central tax identifier at nearly every business-level obligation. Your LLC can NOT complete the state’s mandatory registrations and active compliance measures without it.

a. State Requirement To Provide Your EIN

You must provide an EIN when completing your core state filings. For example, the Florida Business Tax Application (Form DR-1) requires an EIN to establish your tax account.

In most cases, every Florida LLC needs to complete the Florida Business Tax Application. This is because it is required to register for key state tax obligations:

• Other Florida state tax accounts: Administered by the Florida Department of Revenue.
• Sales and use tax: If your LLC sells taxable goods or certain taxable services.
• Reemployment (Unemployment) tax: If your LLC has employees in Florida.

While the IRS treats single-member LLCs as disregarded entities, using an EIN instead of your SSN is the correct compliance measure under C.F.R. § 301.6109-1(d)(4). This states that individuals should use an EIN for business-related tax reporting rather than relying on their SSN.

Using an EIN ensures that your SSN is NOT your permanent business identifier. This applies to your business’s tax reporting and operational matters. I’ve explained this in more detail below.

b. Penalties For Non-Compliance

The state of Florida does NOT punish you if you don’t have an EIN. You face penalties for the obligations that you can’t complete without one.

Example: You can’t obtain a sales & use tax permit without an EIN. You continue selling taxable goods and/or services in the state.

• This is classed as a first-degree misdemeanor under Florida Statute § 212.18(3)(d).
• You face up to 1 year in county jail, as provided in Florida Statutes § 775.082.
• You may be charged with up to a $1,000 fine, pursuant to Florida Statutes § 775.083.

Furthermore, the Department of Revenue may impose the following if you don’t have the correct operating licenses:

• Penalties for failing to collect and remit sales tax.
• You may accrue interest on unreported or late-reported tax.
• You face potential collection actions by the Department of Revenue.

Without a valid EIN, you can NOT register for local business licenses, open reemployment tax accounts, or maintain up-to-date state records. Each missed registration triggers a separate penalty for failing to complete your obligations rather than not having an EIN.

2. Avoid Federal Legal & Tax Compliance Risks

Your Florida LLC is exposed to three separate liability levels for operating without an EIN:

a. Failure To Furnish Required Taxpayer Identification (EIN Application Violation)

If your LLC is required to file federal tax or information returns but fails to provide a valid EIN, it’s classified as a “failure to furnish required taxpayer identification information.”

This may trigger penalties under the:

1. Internal Revenue Code (IRC) § 6721 regarding IRS filing failure.
2. IRC § 6722 regarding payee statement failure.

Example: Your LLC issues Form 1099 (The IRS information return used to report non-employee payments such as contractor fees) without a valid EIN. This may trigger further penalties under the Internal Revenue Code § 6721 and § 6722.

Generally speaking, you face a “per-return” penalty from the IRS for each missing or incorrect EIN. This is currently up to $330 per return. If the failure is due to intentional disregard, your penalty increases to $660 per return or 10% of the amount required to be reported (whichever is greater).

b. Failure To Properly File And Pay Federal Taxes (Substantive Tax Violations)

You commit substantive federal tax violations if you operate without a valid EIN. This includes late filing, improper filing, and non-payment of your required taxes.

Without an EIN, your Florida LLC can not:

• File federal income tax returns.
• Issue or receive reportable payments.

The following penalties apply under IRC § 6651 if you’re required to file a tax return and fail to do so on time or submit incorrect information.

• $235 penalty per partner per month for Multi-Member LLCs taxed as partnerships by default (For 2025 returns).
• 5% of the unpaid tax for each month (Up to 25%) + additional penalties for LLCs taxed as corporations if no tax is due but a return is required.

c. Failure To Comply With Federal Withholding Obligations

If your LLC has employees and fails to collect or pay overemployment taxes, it faces severe penalties under IRC § 6672. These include fines and imprisonment based on the regulations listed below.

Without an EIN, you can NOT register for payroll tax accounts, report withholdings, or remit employment taxes under your LLC. Therefore, this risk is directly tied to the absence of a valid EIN.

3. Prevent Risks Of Operating Without An LLC’s EIN

In practical terms, an EIN allows your LLC to function as a real operating business inside the U.S. financial and commercial system.

If you don’t have one, you must use a personal bank account and accept payments under your personal SSN. This mixes your personal and business funds, undermining the liability protection given to your LLC.

If you obtain an EIN early, you immediately establish a separate tax identity. This limits your personal information from being exposed and supports healthy credit building and accounting processes. Your LLC can smoothly operate with banking, employees, and financing without having to restructure at a later date.
