Alabama EIN Number for Your LLC 2026

Published by TaxPills | By Malik Abdul Rehman

You have done the hard work. Your Alabama LLC Name Reservation is filed. Your Certificate of Formation has been approved by the Secretary of State. Your LLC officially exists.

Now comes one of the most important steps in the entire process — and thankfully, one of the easiest: getting your Alabama EIN Number.

No fee. No waiting weeks. No complicated forms. If you are a U.S. citizen or resident, you can get your EIN Number in about 15 minutes online, directly from the IRS — completely free.

This guide explains exactly what an EIN is, why your Alabama LLC needs one, who qualifies for online application, and what to do the moment your EIN is approved. It is written for first-time business owners who want straightforward, actionable guidance — not legal jargon.

Where are you in the process? This is Step 5 of the TaxPills Alabama LLC series. If you have not yet filed your formation documents, start with our How to Start an LLC in Alabama guide and work through each step in order.

What Is an Alabama EIN Number?

An EIN — short for Employer Identification Number — is a nine-digit number issued by the Internal Revenue Service (IRS) to identify your business for federal tax purposes. It works exactly like a Social Security Number, but for your business rather than for you as an individual.

You may also see it referred to by other names:

Federal Tax ID Number
Federal Employer Identification Number (FEIN)
Federal Tax Identification Number
Alabama Federal Tax ID Number

All of these terms mean exactly the same thing. When someone asks for your “Tax ID” or “Federal ID,” they are asking for your EIN.

One important clarification that confuses a lot of first-time business owners: your Alabama EIN Number is not the same as an Alabama State Tax ID Number. These are two separate identifiers issued by two different agencies.

Identifier	Issued By	Purpose
EIN (Federal Tax ID)	IRS (Internal Revenue Service)	Federal tax identification
Alabama State Tax ID	Alabama Department of Revenue	State tax accounts (sales tax, etc.)

Your Alabama EIN Number comes from the IRS. Your Alabama state tax accounts are set up separately through the Alabama Department of Revenue. Both may be needed depending on your business activities — but the EIN always comes first.

Why Does Your Alabama LLC Need an EIN Number?

Some business owners wonder whether they truly need an EIN if they have no employees. The short answer is yes — and the reasons go beyond payroll.

Your Alabama EIN Number is required for nearly every significant business activity your LLC will undertake:

Banking: Every major bank requires an EIN to open a business checking account. You cannot separate your business and personal finances — a critical step for maintaining your LLC’s liability protection — without one. See our note on business banking below.

Federal Tax Filing: Your EIN is how the IRS tracks your LLC’s tax obligations, whether you file as a sole proprietorship, partnership, or elected corporation.

Alabama State Tax Filing: The Alabama Department of Revenue requires your EIN before you can file the Alabama Business Privilege Tax returns. You cannot complete your Form BPT-IN or annual Form PPT without it.

Alabama Sales Tax Registration: If your LLC sells taxable goods or services, you must register for a sales tax account with the Alabama Department of Revenue — and that registration requires your EIN.

Business Credit: Lenders, suppliers, and vendors use your EIN to verify your business and extend credit. Building business credit separately from your personal credit starts with having an EIN.

Business Licenses and Permits: Many local and state license applications require your EIN as part of the application.

Employee Payroll: If you ever hire employees, your EIN is mandatory for payroll tax reporting, W-2 issuance, and employer registration.

The bottom line: get your Alabama EIN Number right after your LLC is approved. Do not wait until you need it for something specific — by then, the delay will cost you time and potentially hold up your banking or tax filings.

How Much Does an Alabama EIN Number Cost?

Nothing. Zero. Free.

The IRS does not charge any fee to apply for an EIN. If you are applying yourself — which this guide shows you how to do — there is no cost at all.

You may come across third-party services that charge $50, $100, or more to obtain an EIN on your behalf. These services are not doing anything you cannot do yourself. They are simply filling out the same free IRS form on your behalf and charging for the convenience. Unless you have a specific reason to use an intermediary (for example, if you are a non-U.S. resident without an SSN), there is no reason to pay anyone to get your Alabama EIN Number.

When Should You Apply for Your Alabama EIN Number?

Apply for your Alabama EIN Number after your LLC is approved — not before.

This is an important sequence to follow. The IRS uses your LLC’s legal name and state registration details when issuing your EIN. If you apply before your LLC is officially formed and approved by the Alabama Secretary of State, you may create an EIN that does not match your actual registered LLC — which creates complications to fix later.

The correct order is:

Reserve your Alabama LLC Name ✅
File your Alabama LLC Certificate of Formation ✅
Receive your approved Certificate of Formation from the Secretary of State ✅
Apply for your Alabama EIN Number ← You are here
File your Initial Business Privilege Tax Return (Form BPT-IN) — see our Alabama Business Privilege Tax guide
Open your business bank account

Also, before you apply for your EIN, finalize how many members (owners) your LLC has. Changing your LLC from single-member to multi-member — or vice versa — after you have already received your EIN requires additional IRS filings, an updated Operating Agreement, and potentially amended state registrations. It is much easier to have this decided before you start the EIN application.

How to Get Your Alabama EIN Number: Two Paths

Path 1: Online Application — For U.S. Citizens and Residents With an SSN or ITIN

If you are a U.S. citizen or resident alien and you have either a Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN), you can apply for your Alabama EIN Number online through the IRS website. This is by far the fastest and simplest method.

Time required: Approximately 15 minutes Cost: Free Result: Your EIN is issued immediately at the end of the application

Here is how to complete the online EIN application step by step:

Step 1: Go to the IRS EIN Application Visit the IRS EIN Online Application page. The application is available Monday through Friday, 7:00 AM to 10:00 PM Eastern Time. It is not available on weekends or federal holidays.

Step 2: Click “Apply Online Now” This takes you directly into the EIN Assistant — a guided interview-style application that walks you through each section one question at a time.

Step 3: Select Your Entity Type When asked about your entity type, select “Limited Liability Company (LLC)”. Do not select “Sole Proprietorship” or “Partnership” — even if your LLC is taxed that way. Your entity type is LLC; the tax classification is a separate matter.

Step 4: Enter the Number of Members The IRS will ask how many members your LLC has. Enter the correct number. A single-member LLC (one owner) is taxed differently from a multi-member LLC (two or more owners) by default, so accuracy here matters.

Step 5: Select the Reason You Are Applying Most new LLC owners select “Started a new business” as the reason for applying.

Step 6: Enter Your LLC’s Information You will be asked for:

Your LLC’s legal name (exactly as it appears on your approved Certificate of Formation)
Your LLC’s principal business address
The state where your LLC was formed (select Alabama)
The county where your business is located

For the business address, you can use your home address, your Registered Agent’s address, or any reliable mailing address where the IRS can send correspondence. There is no requirement for it to be a commercial address.

Step 7: Enter the Responsible Party’s Information The “Responsible Party” is the individual who owns or controls the LLC and is responsible for its federal tax matters. For most single-owner LLCs, this is you. Enter your full legal name and Social Security Number (SSN) or ITIN.

This information is kept with the IRS and is not published publicly.

Step 8: Review and Submit Review your application for accuracy. Pay close attention to your LLC’s legal name — it must match your Certificate of Formation exactly, including capitalization and punctuation (or lack thereof).

Step 9: Download Your EIN Confirmation Letter Immediately Once your application is submitted and approved, your EIN is issued on the spot. At the end of the session, you will be given the option to download your EIN Confirmation Letter (CP 575).

Download this document immediately. Print at least two physical copies and save a digital copy in a secure location. You will need this letter to:

Open your business bank account
File your Alabama Business Privilege Tax returns
Complete any business license or permit applications
Register for Alabama sales tax (if applicable)

Critical: If you close the browser window without downloading the CP 575, the IRS will mail a copy to the address on your application — but this takes 4–6 weeks. Avoid this entirely by downloading the letter before closing the session.

Path 2: Mail or Fax — For Non-U.S. Residents Without an SSN or ITIN

If you are a non-U.S. resident or citizen who does not have a Social Security Number or ITIN, you cannot use the IRS online application. You must apply by mail or fax using IRS Form SS-4 — the official EIN application form.

Time required: 4–6 weeks by mail; 1–2 weeks by fax Cost: Free Form: IRS Form SS-4

Here is how to apply:

Step 1: Download Form SS-4 Download the current version of IRS Form SS-4 from the IRS website.

Step 2: Complete the Form Fill out all required sections, including:

Your LLC’s legal name (Line 1)
Business address (Lines 4–5)
Type of entity — LLC (Line 8)
Number of LLC members (Line 8b)
Reason for applying (Line 10) — select “Started a new business”
Principal business activity (Line 16)

For the Responsible Party section, a non-U.S. resident without an SSN will typically enter their individual name and indicate they do not have an SSN. The IRS will still process the application and issue an EIN.

Step 3: Fax or Mail Your Form SS-4

By fax (faster — 1–2 weeks): Fax your completed Form SS-4 to the IRS at (855) 641-6935. Keep your fax confirmation receipt as proof of submission.

By mail (slower — 4–6 weeks): Mail your completed Form SS-4 to: Internal Revenue Service Attn: EIN Operation Cincinnati, OH 45999

Step 4: Receive Your EIN by Mail The IRS will mail your EIN Confirmation Letter (CP 575) to the address provided on your Form SS-4. This is your official EIN approval document — store it securely.

Important note for non-U.S. residents: You do not need to hire a third-party service or designee to obtain your Alabama EIN Number. Many services charge fees for this, but you are fully entitled to apply directly yourself at no cost.

What Happens After You Get Your Alabama EIN Number?

Your EIN approval is a milestone. Here is what to do immediately after receiving it:

Open a Business Bank Account

Your Alabama EIN Number and EIN Confirmation Letter (CP 575) are the primary documents you need to open a business checking account. Bring these along with your approved Certificate of Formation and Operating Agreement to your chosen bank.

Opening a dedicated business bank account is not optional if you want to maintain your LLC’s liability protection. Mixing personal and business funds — called “commingling” — is one of the most common ways business owners unknowingly weaken the legal separation their LLC is supposed to provide.

When choosing a bank, compare:

Monthly fees and minimum balance requirements
Online banking and mobile deposit capabilities
Ease of integration with accounting software (such as QuickBooks)
Availability of business debit cards and credit lines

File Your Initial Business Privilege Tax Return (Form BPT-IN)

Your EIN is required to file the Initial Business Privilege Tax Return with the Alabama Department of Revenue. This filing is due within 2.5 months of your LLC’s formation date. Do not delay — this deadline is calculated from your Certificate of Formation approval date, not from when you receive your EIN.

Read our complete Alabama Business Privilege Tax guide for full instructions on Form BPT-IN and the annual Form PPT.

Register for Alabama Sales Tax (If Applicable)

If your LLC sells taxable products or services to Alabama customers, you must register for a sales tax permit with the Alabama Department of Revenue. Your EIN is required for this registration.

Common Alabama EIN Mistakes — and How to Avoid Them

Applying before your LLC is approved. Always wait for your Certificate of Formation to be approved before applying for your EIN. Applying early can result in an EIN that does not match your registered LLC details.

Using the wrong entity type in the application. Select “Limited Liability Company” as your entity type regardless of how your LLC is taxed. Tax classification (sole proprietorship, partnership, S-corp) is a separate election made with the IRS — it does not change what you select in the EIN application.

Entering the wrong number of members. Selecting single-member vs. multi-member determines your LLC’s default federal tax treatment. A single-member LLC is taxed as a sole proprietorship by default; a multi-member LLC is taxed as a partnership. Make sure your selection matches your actual ownership structure.

Closing the browser before downloading the CP 575. Once your EIN is issued online, you have one opportunity to download the Confirmation Letter in that session. If you close the browser before downloading, you will wait 4–6 weeks for the IRS to mail it. Always download immediately.

Losing the EIN Confirmation Letter. If you lose your CP 575, you can request an EIN Verification Letter (Form 147C) by calling the IRS Business & Specialty Tax Line at 1-800-829-4933. This serves the same purpose as the CP 575 for most banks and government agencies.

Alabama EIN Number — Frequently Asked Questions

Does a single-member LLC need an Alabama EIN Number? Yes. Even if you have no employees and your LLC is taxed as a sole proprietorship, you still need an EIN to open a business bank account, file Alabama Business Privilege Tax returns, and handle most business-related registrations.

Can I use my Social Security Number instead of an EIN for my LLC? Technically, a single-member LLC can use the owner’s SSN for some federal tax purposes. However, this is not advisable for privacy or business credibility reasons. Banks typically require an EIN to open an LLC business account regardless. Getting an EIN is free and takes 15 minutes — there is no good reason to avoid it.

What if I applied for an EIN before my Alabama LLC was approved? This creates a mismatch between your EIN record and your LLC’s legal registration. You may need to contact the IRS Business & Specialty Tax Line at 1-800-829-4933 to update your LLC’s details on the EIN record, or in some cases, cancel the premature EIN and apply for a new one after approval.

Does my LLC’s DBA (Trade Name) need a separate EIN? No. A DBA is simply a name your LLC operates under — it is not a separate legal entity. Your existing EIN covers all business activities conducted under your LLC, regardless of how many DBAs you register.

My LLC has two members. Do we each get separate EINs? No. The LLC receives one EIN. Individual members do not receive their own EINs for the LLC. Members report their share of LLC income on their personal tax returns using their individual SSNs or ITINs.

Do I need a new EIN if I add a member to my LLC? In most cases, no. However, changing from a single-member LLC to a multi-member LLC changes your default tax classification (from sole proprietorship to partnership), which requires filing IRS Form 8832 to update your tax status. The EIN itself typically remains the same. Consult a tax professional before making ownership changes.

Can a non-U.S. citizen get an Alabama EIN Number? Yes. Non-U.S. residents who do not have an SSN or ITIN can still obtain an EIN by completing IRS Form SS-4 and submitting it by fax or mail. There is no citizenship requirement for obtaining an EIN. This makes it possible for foreign entrepreneurs to form and operate an Alabama LLC with full U.S. tax compliance.

How do I contact the IRS if I have questions about my EIN? Call the IRS Business & Specialty Tax Line at 1-800-829-4933. Hours are Monday through Friday, 7:00 AM to 7:00 PM local time. When prompted:

Press 1 for English
Press 1 for Employer Identification Numbers
Press 3 to speak with a live representative

Call right when they open to minimize hold times. The IRS can confirm your EIN, update business details, or issue a replacement verification letter.
