How to Get a Tax ID Number in Maine for a New Business (Indiana Context)

What “Tax ID Number” Means for a New Business

“Tax ID number” is a common umbrella term. For most new businesses, it can refer to one or more of the following identifiers:

• Federal EIN (Employer Identification Number) issued by the IRS for federal tax filings, hiring employees, and opening many business bank accounts.
• State tax account numbers used for state-level obligations such as sales tax collection, withholding tax for employees, and certain excise or specialty taxes.
• Local or industry registrations that may be required depending on your city, county, or regulated activity.

Start with the Right State: Maine Title vs. Indiana Registration

This guide uses the title “Maine,” but your state tax registration must match where you operate. If your new business is operating in Indiana (IN), you typically obtain:

• A Federal EIN (if needed), and
• An Indiana state tax registration for sales tax (Registered Retail Merchant Certificate), withholding tax, and other applicable accounts.

If you are actually starting a business in Maine, the overall process is similar (EIN + Maine state registrations), but the state portal, forms, and account types differ. Many businesses operate in more than one state; in that case, you may need registrations in each state where you have nexus.

Indiana Quick Reference (Sales Tax + Major Cities and Counties)

Step 1: Decide Whether You Need a Federal EIN

You generally need an EIN if any of the following apply:

• You will hire employees.
• You operate as a partnership or corporation.
• You want to open certain business bank accounts or apply for business credit.
• You have certain federal tax filing needs (including some excise taxes).

Sole proprietors with no employees sometimes use a Social Security Number for federal tax purposes, but many still choose an EIN for privacy and business banking.

Information to Gather Before Applying for an EIN

• Legal business name (and DBA, if applicable)
• Entity type (sole proprietor, LLC, corporation, partnership)
• Responsible party name and taxpayer identification
• Business address and mailing address
• Reason for applying (new business, hiring, banking, etc.)
• Start date and principal activity

Step 2: Register for Indiana State Tax Accounts (If Operating in IN)

If you will operate in Indiana, you typically register through the state’s tax registration process to set up the accounts you need, such as:

• Sales tax (for selling taxable goods and certain taxable services)
• Withholding tax (if you have employees)
• Other applicable accounts depending on your industry

Common Triggers for Indiana Sales Tax Registration

• Selling tangible products to Indiana customers
• Operating a retail location, office, or warehouse in Indiana
• Making deliveries into Indiana using your own vehicles
• Having employees or contractors performing work in Indiana

Step 3: Align Your Business Formation and Tax IDs

Your tax ID setup should match your formation choices and how you’ll actually run the business:

• LLC: You may need an EIN even without employees if taxed as a partnership or corporation, or for banking and vendor onboarding.
• Corporation: An EIN is typically required.
• Sole proprietor: May use an SSN for federal filings, but an EIN is commonly used for business operations.

Also confirm that your business name and address are consistent across filings (formation documents, EIN application, state tax registration, and bank accounts).

Step 4: Use Your Tax IDs Correctly (Banking, Payroll, and Vendors)

After you receive your EIN and any Indiana state tax account numbers:

• Open a dedicated business bank account and keep business funds separate.
• Set up payroll properly if you hire (withholding, unemployment insurance where applicable, and regular filings).
• Collect and store resale/exemption certificates when making tax-exempt sales, if applicable.
• Issue and request the right tax forms for vendors and contractors (for example, W-9 collection).

Practical Tip: Keep a “Compliance Folder”

Maintain a single folder (digital and/or physical) with your EIN confirmation, state registration confirmation, sales tax certificate, and any business verification documents. For vendor onboarding and due diligence workflows, see company business verification.

Step 5: Avoid Common Setup Mistakes

• Registering in the wrong state: If you operate in Indiana, register Indiana accounts; if you operate in Maine, register Maine accounts.
• Mixing personal and business details: Use consistent legal names and addresses across all registrations.
• Collecting sales tax without proper registration: Have your sales tax account active before charging customers.
• Forgetting local requirements: Some cities or counties require additional licensing depending on the business type.
• Not planning for filing frequency: Sales tax and withholding returns may be due monthly, quarterly, or annually depending on activity.

FAQ: Getting a Tax ID Number for a New Business (Maine Title, Indiana Context)

1) If my business is in Indiana, do I still follow “Maine” steps?

No. You can use the same general approach (EIN + state registration), but you must register with Indiana for state tax accounts if you operate in Indiana.

2) What is the difference between an EIN and an Indiana sales tax ID?

An EIN is a federal identifier used for IRS and federal tax purposes. An Indiana sales tax ID is a state registration that authorizes you to collect and remit Indiana sales tax and file related returns.

3) Can I get an EIN if I haven’t formed my LLC yet?

Many owners wait until the entity is formed so the EIN matches the final legal name and structure. If you apply before formation, you risk needing corrections later if the legal details change.

4) Do I need a tax ID number if I’m a sole proprietor with no employees?

You may not be required to have an EIN for federal purposes, but you may still need state registrations (like sales tax) depending on what you sell. Many sole proprietors also choose an EIN for banking and privacy.

5) When should I register for Indiana sales tax?

Register before making taxable sales to Indiana customers so you can properly collect tax from the first taxable transaction and remain aligned with filing requirements.

6) If I sell online, do I need an Indiana sales tax registration?

If you have Indiana nexus (such as in-state operations, inventory, employees, or other connections), registration is typically required. Online selling alone does not eliminate sales tax responsibilities.

7) What information do I need to apply for state tax accounts in Indiana?

Expect to provide your EIN (if applicable), legal entity details, business addresses, ownership/responsible party information, start date, and the tax types you need (sales tax, withholding, etc.).

8) Do I need a separate tax ID for each location in Indiana?

Often you can operate under one primary registration, but additional locations can affect reporting and permits depending on how your accounts are set up and what you do at each site.

9) What happens if I charge customers sales tax before I’m registered?

Charging tax without a valid registration can create compliance issues. It is best to register first, then begin collecting tax and issuing compliant receipts/invoices.

10) If I expand into another state later, will my EIN change?

Your federal EIN typically stays the same. What changes is your need to register for new state tax accounts in each additional state where you establish nexus.
