How to Get an EIN in Indiana

An Employer Identification Number (EIN) is your federal business tax ID. The IRS issues it to identify your business for tax purposes. If you're hiring employees, forming an LLC, starting a corporation, or operating as a partnership, you need an EIN. The good news is getting one is free, straightforward, and usually takes just 15 minutes online.

Who Needs an EIN in Indiana

You need an EIN if you:

  • Plan to hire employees
  • Form an LLC with two or more members
  • Form a corporation (S-corp or C-corp)
  • Operate as a partnership or limited partnership
  • Are a single-member LLC taxed as a corporation
  • Operate as a sole proprietor and want one (optional, but recommended)
  • Run certain farm operations or are a nonprofit

Sole proprietors without employees don't legally need an EIN, but getting one keeps your Social Security Number private for business purposes and is strongly recommended. It's free, so there's no reason not to get one.

What You'll Need Before You Apply

Gather this information before you start your EIN application. The process only takes a few minutes if you have everything ready:

  • Your Social Security Number or Individual Taxpayer Identification Number (ITIN)
  • Your business name (exact legal name, as registered in Indiana)
  • Your business mailing address
  • Your business location address (if different from mailing address)
  • Description of your primary business activity
  • Number of employees you currently have or expect to hire
  • Your business structure type (LLC, S-corp, C-corp, sole proprietorship, etc.)
  • Date you started or plan to start the business

The good news: Indiana doesn't require any state paperwork to get an EIN. This is entirely a federal process through the IRS. The EIN you receive is valid immediately and requires no state registration.

How to Get Your EIN: Five Steps

Step 1: Apply Online (Fastest Method)

The online method is the fastest way to get an EIN. You can apply at the IRS website right now and receive your number immediately. Head to https://www.irs.gov/ein and look for the "Apply for an EIN Online" link. This takes about 10 to 15 minutes.

Click on the online application tool. You'll answer questions about your business, your ownership structure, and your industry. The form is straightforward. Answer each question carefully and match your information exactly to what you filed (or will file) with the Indiana Secretary of State.

At the end of the application, the IRS displays your EIN immediately on the screen. Write it down or screenshot it. The IRS will also email you a confirmation document (Form SS-4, your official EIN assignment). Keep this email and the EIN safe, you'll need it for everything: opening a business bank account, registering with Indiana Department of Revenue, filing taxes, and hiring employees.

Step 2: Apply by Phone (If You Prefer Voice Guidance)

If you prefer to speak with someone, you can apply by phone. Call the IRS Business & Specialty Tax Line at 1-800-829-4933. Have all your information ready before you call. The wait time varies, but the IRS typically answers within 30 minutes to an hour during business hours (7:00 AM to 7:00 PM EST, Monday through Friday).

A representative will walk you through the questions. They'll assign your EIN while you're on the phone and give you the number immediately. Ask them to email you the confirmation. This method works well if you want real-time help or have questions about your specific situation.

Step 3: Apply by Mail (Slowest Option)

If you can't apply online or by phone, you can mail in Form SS-4 (Application for an Employer Identification Number). Download it from the IRS website at https://www.irs.gov/pub/irs-pdf/fss4.pdf. Print it, fill it out by hand, and mail it to:

Internal Revenue Service
Attn: EIN Operation
Cincinnati, OH 45999

Mail processing typically takes 4 to 6 weeks. This is slow, so use this method only if the online and phone options truly aren't available to you. Include a cover letter with your name and the best phone number to reach you. The IRS will call you to confirm information before issuing your EIN.

Step 4: Verify Your Information Matches Your Indiana Filing

Once you have your EIN, confirm it's issued to the exact business name you filed with the Indiana Secretary of State. If you formed an LLC, the name on the EIN should match your Articles of Organization. If there's a mismatch, contact the IRS immediately at the number on your confirmation letter to correct it. A mismatch can delay tax filings and cause problems later.

Step 5: Use Your EIN for Indiana Registration and Business Operations

With your EIN in hand, you're ready for the next steps:

  • Register with Indiana Department of Revenue. You need a state tax ID (separate from your EIN) if you're selling taxable goods or services. Apply for a Registered Retail Merchant Certificate at https://www.in.gov/dor/i-am-a/business-corp/business-education/register-business/. The fee is $25.
  • Open a business bank account. Banks require your EIN to open a business account. Bring your EIN confirmation letter and your driver's license.
  • Apply for licenses and permits. If your business requires a professional license (contractor, realtor, insurance agent, etc.), you'll need your EIN for the application. Check with the Indiana Professional Licensing Agency at https://www.in.gov/pla/.
  • File your business income tax return. Sole proprietors file Schedule C with their personal return. LLCs, S-corps, and C-corps file separate business returns using the EIN.

EIN Processing Times: What to Expect

Online application: EIN issued immediately (same day). You see it on screen and receive a confirmation email within 2 hours.

Phone application: EIN issued during the call (same day). Takes 30 minutes to an hour total, including wait time.

Mail application: Takes 4 to 6 weeks. This is why mail is your last resort.

Your EIN is valid for business use the day it's issued, even before you receive any official paperwork. You can give it to your bank, landlord, or state agencies right away.

Common Mistakes to Avoid

Mistake 1: Mismatching Your Business Name

The EIN application asks for your "legal business name." If you formed an LLC in Indiana, use the exact name from your Articles of Organization, including "LLC" at the end. If you use a different name on the application, the IRS assigns the EIN to the wrong entity, and you'll have a name mismatch on your tax returns. This is a headache to fix.

Mistake 2: Applying Before Your Business is Official

You can apply for an EIN before you file with the Indiana Secretary of State, but make sure your business name choice is locked in. Don't apply for an EIN, then file your LLC under a different name. If you haven't filed yet, do that first, then get the EIN.

Mistake 3: Forgetting to Share Your EIN

Once you get your EIN, you need to give it to everyone who needs it: your bank, your accountant, your registered agent, and the state. Many new business owners get the EIN and then forget to register it with Indiana's tax authority. This can trigger notices and penalties later. Register your Retail Merchant Certificate within a week of getting your EIN.

Mistake 4: Losing Your Confirmation Email

Save that confirmation email. You'll need the EIN for months and years ahead. Put it in a folder or cloud storage. The IRS doesn't re-send it easily if you lose it, and retrieving a lost EIN can take weeks. (You can get it again, but it's slower than just keeping the original email.)

Mistake 5: Confusing EIN with a State Business License

Your EIN is federal only. Indiana doesn't have a single "state business license." You may need a Retail Merchant Certificate (if you sell taxable goods), a professional license (if you're a contractor, nurse, etc.), and local zoning approval or permits. Your EIN is just step one. Don't assume it's your only registration requirement.

Tips for a Smooth EIN Application

Apply online if you can. It's the fastest, simplest method. You walk away with your EIN in minutes. If you have a question, you can call the IRS after you receive it.

Have your business plan nailed down first. Your business structure (LLC vs. S-corp vs. sole proprietor) affects your EIN application. Know what you're forming before you apply. If you're unsure, talk to a CPA or attorney first.

Use your primary Indiana location. If you're home-based, that's fine. Use your actual home address or business office address, not a P.O. Box. The IRS uses this to match records and verify your identity.

Don't wait on the paperwork. You can start operating your business and using your EIN the day it's issued. You don't need to wait for official documents to arrive in the mail.

Confirm with Indiana Department of Revenue.. Within a week of getting your EIN, register for a Retail Merchant Certificate if you sell taxable goods or services. This links your federal EIN to your state records. It's quick and costs $25.

Next Steps After Getting Your EIN

Once you have your EIN, your business setup continues. Here's the order:

  1. File your business formation documents with the Indiana Secretary of State (if you haven't already).
  2. Apply for an EIN from the IRS (the topic of this guide).
  3. Open a business bank account with your EIN and state ID (if needed).
  4. Register for a Retail Merchant Certificate with Indiana Department of Revenue (if you sell taxable goods).
  5. Apply for professional licenses or local permits (if required for your industry).
  6. Set up your business accounting and bookkeeping system.
  7. Start operating and serving customers.

Getting an EIN is one of the fastest steps in the process. Take advantage of that. Apply online today and move on to opening your business bank account and registering with Indiana. The whole process from start to business-ready takes weeks, but your EIN takes minutes.
