How to Get an EIN in Maryland

An Employer Identification Number (EIN) is a federal tax ID issued by the Internal Revenue Service (IRS). If you're forming a business in Maryland, understanding when and how to get an EIN is essential for payroll, banking, and tax compliance. This guide walks you through the federal application process and explains how an EIN fits into your Maryland business formation.

What Is an EIN and Why Maryland Businesses Need One

An EIN is a nine-digit number assigned to a business entity for federal tax purposes. It functions like a Social Security number for your company. The IRS uses the EIN to track business income, employment taxes, and other tax obligations.

If you're operating a business in Maryland as a sole proprietor, you can use your personal Social Security number for federal taxes. However, most business structures require an EIN. If you're forming an LLC in Maryland, starting a corporation, or planning to hire employees, you will need an EIN.

When You Must Get an EIN in Maryland

Maryland state law does not require an EIN to operate a business. However, federal law mandates an EIN in these situations:

  • You are forming a partnership, LLC, S corporation, or C corporation.
  • You plan to hire employees and need to withhold payroll taxes.
  • You operate as a sole proprietor but want to keep business finances separate from personal finances (optional but recommended for banking).
  • You are a non-profit organization or trust.
  • You operate a farm or have farm-related income.
  • You have a retirement plan for your business.
  • Your business files excise tax returns or alcohol, tobacco, or firearms permits.

Most Maryland LLCs and corporations need an EIN immediately upon formation, even before hiring anyone.

What You'll Need Before Applying for an EIN

Gather these materials before starting your EIN application:

  • Your Social Security number or ITIN (if you are the owner or responsible party)
  • Proof of business formation documents if you've already filed with Maryland, such as your Articles of Organization for an LLC or Articles of Incorporation for a corporation
  • Anticipated start date of your business
  • Type of business structure (LLC, corporation, partnership, sole proprietorship, etc.)
  • Principal business activity or industry classification
  • Expected number of employees in the first year
  • Business address (not a P.O. box, though virtual addresses may be permitted)
  • Phone number for the business

You do not need your Maryland registration to be complete before applying for an EIN. You can apply before, during, or shortly after filing your Articles of Organization with the Maryland SDAT.

How to Get an EIN: Three Methods

Method 1: Apply Online (Fastest)

The IRS online EIN application system is the fastest and easiest method. The application is free and takes 10 to 15 minutes. You receive your EIN immediately upon successful completion.

Steps:

  1. Go to the IRS EIN application website at https://www.irs.gov/ein or use the Business Name Search tool.
  2. Select "Apply for an EIN Online" and answer the eligibility questions.
  3. Provide your responsible party information (typically the owner or managing member if you have an LLC).
  4. Answer questions about your business structure, principal business activity, and expected payroll.
  5. Review your information and confirm it is accurate. You cannot edit a submitted application online.
  6. Submit the application. Upon confirmation, the IRS displays your new EIN on screen.
  7. Print or save the confirmation page immediately. Keep it in your records.

The IRS system is available 24/7, including weekends and holidays. There are no restrictions on who can apply online, even non-U.S. citizens with valid ITINs.

Method 2: Mail Form SS-4 to the IRS

If you prefer to apply by mail or cannot apply online, complete IRS Form SS-4 (Application for Employer Identification Number).

Steps:

  1. Download or print Form SS-4 from the IRS website at https://www.irs.gov/forms-pubs.
  2. Fill out every line of the form. The form is straightforward but requires careful attention to detail.
  3. Mail the completed form to the IRS office assigned to your state. For Maryland, mail to the IRS address listed on the form instructions.
  4. Allow 4 to 6 weeks for processing. The IRS will mail your EIN and a notice to your business address.

The IRS address for Maryland is: Internal Revenue Service, EIN Operation, Philadelphia, PA 19255. Check the current Form SS-4 instructions to confirm the correct address, as this may change.

Method 3: Apply by Telephone

You can apply by calling the IRS Business & Specialty Tax Line at 1-800-829-4933. This method takes about 10 minutes and you receive your EIN the same day.

Before calling, have ready:

  • Your responsible party's Social Security number or ITIN
  • Business name and address
  • Type of business entity
  • Principal business activity
  • Expected date you will start paying wages

The IRS phone line is open Monday through Friday, 7:00 a.m. to 10:00 p.m. Eastern Time. Wait times can be long, especially during tax season. Online is faster in most cases.

Processing Times and What to Expect

EIN processing timelines depend on the method you choose:

Method Processing Time Cost
Online application Immediate (displayed on screen) Free
Telephone Same day Free
Mail (Form SS-4) 4 to 6 weeks Free

There is no fee for applying for an EIN. Any service charging you to get an EIN is overcharging you and is unnecessary. The IRS offers EIN applications at no cost.

After receiving your EIN, the IRS may send you tax packets and notices by mail over the following weeks. These are routine and do not require immediate action, though you should review them to understand your filing deadlines and tax obligations.

Tips and Common Mistakes to Avoid

Tip 1: Apply Online Immediately After Formation

Don't delay. If you've formed an LLC or corporation with Maryland SDAT, apply for your EIN the same day or the next business day. This keeps your business formation and tax registration on track.

Tip 2: Use the Correct Business Name and Address

The name on your EIN application must match the name on your Maryland Articles of Organization or Articles of Incorporation exactly. If you've filed a trade name (DBA) with Maryland, use the registered trade name, not your personal name.

Tip 3: Designate a Responsible Party

The IRS requires a responsible party: the person who has authority over the business. For most LLCs, this is the managing member or owner. For corporations, it's typically the president or principal officer. This person does not need to be the only owner.

Tip 4: Save Your Confirmation Number and EIN

If you apply online, immediately print or save your EIN confirmation page. You will need this when opening a business bank account, registering for Maryland state taxes, or filing your first return.

Common Mistake 1: Confusing EIN with Maryland State Tax ID

An EIN is federal only. Maryland also requires state-level tax registration. You will need both. After getting your EIN, you must register with the Maryland Comptroller for sales and use taxes if you sell taxable goods or services. The Comptroller's sales tax license is separate from your EIN.

Common Mistake 2: Applying Multiple Times

Do not submit more than one EIN application. If you submit the form twice, the IRS may issue two EINs or experience delays. If you accidentally apply twice, contact the IRS immediately to deactivate one EIN.

Common Mistake 3: Using the Wrong Business Address

The IRS requires a street address, not a P.O. box. Use your actual business location. If you use a registered agent's address for Maryland business purposes, use that address on the EIN form as well.

Common Mistake 4: Delaying State Registration After Getting an EIN

Getting an EIN does not register your business with Maryland. You still need to file Articles of Organization with SDAT and register for Maryland state taxes. Do both within 30 days of getting your EIN to avoid penalties and to ensure you are in compliance.

After You Get Your EIN: Next Maryland Business Steps

Once you have your EIN in hand, complete these Maryland registrations:

  1. Maryland state tax registration: Register for sales tax (if applicable) and employer withholding tax through the Maryland Comptroller at https://businessexpress.maryland.gov.
  2. Maryland business licensing: If you sell goods in Maryland, obtain a trader's license from your county Clerk of the Circuit Court (around 50 to 100 dollars, valid May 1 through April 30).
  3. Business bank account: Open a business bank account in your business name using your EIN and Maryland formation documents.
  4. Payroll setup: If hiring employees, enroll in the Maryland Department of Labor for unemployment insurance and set up payroll withholding.
