How to Get an EIN in Pennsylvania

An Employer Identification Number (EIN) is a nine-digit federal tax ID issued by the IRS. If you're starting a Pennsylvania business, you'll likely need an EIN to hire employees, open a business bank account, and file corporate or partnership tax returns. This guide walks you through the exact process, timeline, and what comes next.

What Is an EIN and Why You Need One

An EIN is your business's unique tax identification number, separate from your personal Social Security number. The IRS uses it to track your business's federal tax obligations. Think of it as a Social Security number for your company.

The good news: EINs are free to obtain and issued on the spot if you apply online. The better news: you don't need to visit a Pennsylvania state office to get one. The IRS issues EINs to businesses nationwide from its federal database.

Pennsylvania businesses file state income taxes separately (Personal Income Tax at 3.07% for pass-through entities, Corporate Net Income Tax at 7.49% for corporations in 2026). Your EIN is the bridge between your business structure and both federal and state tax filing.

Do You Need an EIN? Criteria That Trigger the Requirement

Not every Pennsylvania business needs an EIN immediately. Here's when you do:

• You have employees (even one part-time worker). This is the most common reason.
• Your business structure is a corporation, partnership, or LLC with multiple members.
• You operate as a sole proprietor but want to keep business and personal finances separate (optional, but recommended).
• You file any of these tax forms: corporate income tax return, employment tax return, excise tax return, or partnership return.
• Your business generates over $1,000 in annual revenue (threshold varies by structure).
• You're a nonprofit organization or trust.
• You operate as an S corporation or a disregarded entity that wants a separate tax ID.

If you're a sole proprietor with no employees and few income sources, you can use your Social Security number for federal tax purposes. But you still need to register for Pennsylvania state taxes separately.

Information and Materials You'll Need

Before you apply, gather these items. The IRS will ask for them whether you apply online, by phone, or by mail:

• Your Social Security number (if you're the owner).
• Your legal business name exactly as it appears on your Articles of Incorporation, Certificate of Organization, or formation document.
• Your business's principal place of business address in Pennsylvania (street address, not a PO box).
• Your business structure: sole proprietorship, LLC, S corporation, C corporation, partnership, or nonprofit.
• A description of your main business activity (what you actually do: retail sales, consulting, manufacturing, etc.).
• The date you began or will begin your business.
• Your expected first payroll date (if hiring).
• The number of people you expect to employ (include yourself).

You do not need your Pennsylvania business formation documents in hand to apply for an EIN. You can apply before or after filing with the Pennsylvania Department of State. However, your business name must be exact and must match your formation documents.

Step-by-Step: How to Get an EIN in Pennsylvania

Method 1: Apply Online (Fastest)

This is the fastest and easiest method. You'll receive your EIN immediately after submission.

1. Go to the IRS website. Visit irs.gov and search for "Apply for an EIN Online." The direct page is irs.gov/ein. No login required.
2. Click "Apply Online Now." This opens the IRS's interactive tool. It guides you through each question one step at a time.
3. Verify your location. The tool first confirms that your principal place of business is in the United States. Select Pennsylvania from the state dropdown.
4. Select your business structure. Choose from: sole proprietor, LLC, partnership, corporation, nonprofit, trust, or other. The tool's questions adapt based on your choice. Be precise. For example, if you're an LLC with two members, select "LLC" and it will ask how many members you have.
5. Provide your business information. Enter your legal business name exactly as it appears (or will appear) on your Pennsylvania filing documents. This is critical: if your formation document says "Smith Family Consulting LLC" but you enter "Smith Consulting," there will be a mismatch. The IRS will ask if you operate under any "doing business as" name (DBA). In Pennsylvania, DBAs are registered separately; for now, leave this blank unless you're already registered.
6. Enter your Pennsylvania business address. Street address only: no PO box. This should be the physical location where your business operates or is managed. If you work from home, use your home address. The IRS may ask if this address is rented or owned (for record purposes only).
7. Describe your principal business activity. Be specific: "Bookkeeping services" not "Services." "Specialty coffee retail" not "Retail." The IRS uses this to categorize your business for tax purposes.
8. Provide the business start date. Enter the date you have begun business or plan to begin. If you're filing for an LLC in Pennsylvania now, use today's date or a date very close to when you expect the Pennsylvania Secretary of State to approve your filing.
9. Answer employment questions. The tool will ask if you have employees or will have them. If yes, provide the date of your first payroll. This is when you first pay an employee (not when you hire them; hiring and first paycheck can be weeks apart). If you're sole proprietor with no employees, select "No."
10. Confirm your responsible party. Name the person responsible for the business. This is usually the owner. Provide their name, date of birth, and a daytime telephone number. For an LLC or partnership, this might not be you if there are multiple owners; the IRS typically wants the owner with the most control.
11. Review your entries. The tool displays everything you entered. Check it carefully. A typo in your business name or address means you'll have to request an amended EIN later (or it could complicate state tax filing).
12. Submit and receive your EIN. Click submit. If everything is correct, you'll receive a confirmation page with your nine-digit EIN displayed. Write it down immediately. Screenshot or print the page. The IRS will send written confirmation by mail within two weeks, but the number is active instantly.

Method 2: Apply by Telephone

Call the IRS Business and Specialty Tax Line at 1-800-829-4933. Hours: Monday to Friday, 7 a.m. to 10 p.m. Eastern Time. Have all the information listed above ready. The agent will ask the same questions as the online form and issue your EIN over the phone. You'll receive written confirmation by mail.

Method 3: Apply by Mail or Fax

File Form SS-4 (Application for Employer Identification Number) and mail it to the IRS address for Pennsylvania (the form will list the correct address). Processing time: 2 to 4 weeks. You can also fax Form SS-4, but the IRS recommends online or phone for speed.

Download Form SS-4 at irs.gov. Instructions are included. This method is only advisable if you can't access the internet or phone, as it's the slowest option.

Timeline Expectations

Apply online or call if you need the number right away. Most Pennsylvania businesses use the online method and have an EIN within minutes.

After You Get Your EIN: Pennsylvania Tax Registration

Getting a federal EIN is only the first step. You must also register for Pennsylvania state taxes. Here's what comes next:

Register with Pennsylvania Department of Revenue

Visit revenue.pa.gov and select "Register My Business for Taxes." You'll register for any state taxes your business owes. Common registrations:

• Personal Income Tax Withholding (if you hire employees in Pennsylvania).
• Sales Tax License (if you sell tangible goods).
• Corporate Net Income Tax (if your business is structured as a C corporation).

You'll need your new EIN to complete these registrations. Processing time: typically a few business days. You can apply online or by mail.

Open a Business Bank Account

Use your EIN to open a business checking account. Bring:

• Your EIN confirmation letter from the IRS (or the number and screenshot).
• Photo ID.
• Your Pennsylvania business formation documents (Certificate of Organization for an LLC, Articles of Incorporation for a corporation, etc.).
• An initial deposit (amount varies by bank).

Separating business and personal money is not optional; it protects your personal liability and simplifies tax filing. Most Pennsylvania banks offer business accounts. Pennsylvania Small Business Development Centers (pasbdc.org) can recommend banks if you're unsure.

Common Mistakes to Avoid

• Entering the wrong business name. If your Pennsylvania formation document says "Williams Marketing Solutions LLC" but you enter "Williams Marketing," there's a mismatch. The IRS will issue the EIN to the name you entered, and state tax forms will reject it later. Triple-check spelling and legal structure abbreviations.
• Using a PO box as your principal address. The IRS requires a physical street address. A PO box disqualifies your application. Your home address is acceptable if that's where business happens.
• Mismatching the start date. If you enter a start date of tomorrow but don't actually begin business for three months, it creates a record gap. Use the actual (or realistic projected) date you begin.
• Forgetting to register for Pennsylvania state taxes. Getting an EIN does not automatically register you with Pennsylvania. You must file separately with the Department of Revenue. Forgetting this can result in penalties and missed filing deadlines.
• Assuming you need an EIN if you don't. If you're a sole proprietor with no employees and no separate business structure, you can file federal taxes under your Social Security number. An EIN is optional for you (but recommended for business legitimacy and privacy).
• Losing your EIN confirmation. Take a screenshot, print the page, or photograph it. The IRS will mail confirmation, but that takes time. You need the number immediately to open accounts and register with Pennsylvania.

Tips for Success

• Apply online. It's free, instant, and requires no phone calls or wait times. The IRS website is straightforward and guides you through every field.
• Use your legal business name exactly. Match it word-for-word to your Pennsylvania formation documents (or the name you plan to use on those documents). Typos here mean headaches later.
• Apply before you need it, but not too early. If you're forming an LLC in Pennsylvania, you can apply for an EIN the same day you file with the Secretary of State. You don't need a physical office yet, just an address where the business will operate.
• Save your EIN for reference. You'll need it for bank accounts, state tax registration, payroll setup, and vendor accounts. Keep a record in a safe place (digital and paper).
• Pair this with Pennsylvania business formation. If you haven't filed your Articles of Organization (LLC) or Articles of Incorporation (corporation) with the Pennsylvania Department of State yet, do so before or immediately after getting your EIN. Your state business structure and federal EIN work together.

What to Expect After Getting Your EIN

Once issued, your EIN is permanent. It doesn't expire, even if your business closes. The IRS will:

• Mail a written confirmation letter within 2 weeks.
• Activate your EIN in their system immediately (it works right away).
• Allow you to file federal employment and income tax returns under that number.

You will not owe anything. EINs are always free. If a service charges you to apply, you're using a third party, not the IRS directly.

Your Next Steps in Pennsylvania

After your EIN is active:

1. Register for Pennsylvania state taxes at revenue.pa.gov (required within 10 days of hiring your first Pennsylvania employee).
2. Open a business bank account using your EIN.
3. If you hire employees, set up federal payroll tax withholding and state withholding through the Pennsylvania Department of Revenue.
4. Keep your EIN and all IRS correspondence in a secure location for your records.
