How to Get an EIN in Pennsylvania (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

An EIN is a free federal tax ID from the IRS — there is no Pennsylvania-specific EIN. The fastest way to get one is the online EIN Assistant, which issues the number immediately during a single session. After that, you register Pennsylvania state tax accounts with the Department of Revenue through myPATH.

What an EIN Is and Why It's Free

An Employer Identification Number (EIN) is a nine-digit federal tax ID the IRS assigns to businesses, much like a Social Security number for a company. It is issued by the IRS at no cost — there is no Pennsylvania-specific EIN and no legitimate reason to pay a third party for one. You use the EIN to open a bank account, hire employees, file federal and state taxes, and identify your business.

Whether you are forming a Pennsylvania LLC, corporation, or partnership, the EIN process is the same federal procedure. For the national overview, see how to get an EIN and the EIN basics. After the EIN, Pennsylvania has its own tax registration, covered below.

Do You Need an EIN?

You need an EIN if your business has employees, operates as a partnership or corporation, is a multi-member LLC, or files certain excise or employment tax returns. A single-member LLC generally needs one to open a business bank account and if it has employees. A solo sole proprietor with no employees may use their Social Security number, but many still get an EIN to keep the SSN private.

Getting an EIN early simplifies banking and hiring. If you are unsure, most banks and payroll providers will require one. See the how to form an LLC hub for where the EIN fits in forming a Pennsylvania business.

The Responsible Party

Every EIN application must name a responsible party — the individual who ultimately owns or controls the entity and directs its funds and assets. The responsible party must have a valid SSN or ITIN. For most small businesses, this is the owner or a managing member. Only one responsible party is listed, even if there are multiple owners.

If the responsible party has an ITIN rather than an SSN, the online EIN Assistant may not be available, and you would apply by fax or mail with Form SS-4 instead. The IRS limits issuance to one EIN per responsible party per day, so plan accordingly if you are forming several entities.

How to Apply

The fastest method is the free online EIN Assistant on the IRS website, available on weekdays during posted hours. You complete the application in a single session (it does not save partway), answer questions about the entity and responsible party, and receive the EIN immediately at the end, with a downloadable confirmation (CP 575).

If you cannot use the online tool — for example, an international applicant or an ITIN-based responsible party — you can file Form SS-4 by fax (typically a few business days) or by mail (longer). See how to get an EIN for the full comparison of methods and timing.

Register Pennsylvania Tax Accounts

The EIN is federal; Pennsylvania has its own registration. After getting the EIN, register with the Pennsylvania Department of Revenue through myPATH using the PA Enterprise Registration (historically Form PA-100) to set up accounts such as sales tax license (free), employer withholding, and unemployment compensation. This is how the state ties your EIN to Pennsylvania tax obligations.

You also register your entity itself with the Pennsylvania Department of State when you form it. Your free EIN identifies the business across these systems. See Pennsylvania LLC tax filing and the business tax overview for what to file after registering.

After You Have Your EIN

Once you have the EIN, use it to open a business bank account (keeping finances separate supports your liability shield), set up payroll if you hire, and file federal and Pennsylvania returns. Store the CP 575 confirmation with your records; if you lose it, the IRS can send a confirmation letter (147C) but does not reissue the original.

Keep your entity in good standing by maintaining a registered office/agent, filing required reports, and meeting tax deadlines. The EIN stays with the business for its life; you generally need a new one only if the entity type or ownership structure fundamentally changes.

Using, Protecting, and Replacing Your EIN

Once issued, your EIN is used everywhere your business identifies itself to the government and financial institutions: opening a bank account, running payroll, filing federal returns, and registering Pennsylvania tax accounts through myPATH. Treat it as sensitive information — it identifies your business much like an SSN identifies a person — and share it only when required.

Store your CP 575 confirmation letter securely. If you lose it, the IRS will not reissue the original, but you can request a confirmation letter (147C) by phone that serves the same verification purpose for banks and lenders. Keeping the original with your formation documents avoids that extra step.

Know when you need a new EIN. Generally, an EIN stays with the business for its life. You typically need a new one only when the entity's structure changes fundamentally — for example, a sole proprietorship incorporates, or ownership changes create a new entity. Routine changes like a new address or business name usually do not require a new EIN.

After the EIN, complete Pennsylvania registration. Use myPATH to open the business tax accounts you need — sales tax license, employer withholding, unemployment — and register the entity with the Department of State when you form it. Your EIN links these systems. See Pennsylvania LLC tax filing for what to file next.

Beware of third parties charging to "get" your EIN. The IRS never charges, and the online EIN Assistant issues the number immediately for free. If a website asks for a fee, you are paying a middleman for a free government service. Apply directly with the IRS, or see how to get an EIN for the official methods.

Prepare your details before you open the EIN Assistant. Because the online session does not save and times out, have your legal name, entity type, formation date, responsible party's SSN or ITIN, and business address ready. Completing the application in one focused sitting avoids restarting and gets you the number and CP 575 confirmation immediately.

Choose the right application method for your situation. Most domestic applicants use the free online tool, but an international applicant or a responsible party with an ITIN may need to file Form SS-4 by fax or mail. Knowing which path applies prevents a failed online attempt and the delay of starting over through a slower channel.

Sequence the EIN with your other setup steps. You generally form the entity, obtain the EIN, open a bank account, and then register Pennsylvania tax accounts through myPATH. Doing them in order avoids friction, since banks want the EIN and formation document, and the state tax accounts reference the EIN once you have it.

Protect and reuse the EIN over the life of the business. Store the confirmation securely, share the number only when required, and remember you usually keep the same EIN unless the entity's structure fundamentally changes. Completing Pennsylvania registration — sales tax license, withholding, unemployment — through myPATH ties everything to that one identifier. See Pennsylvania LLC tax filing.

Line up the surrounding registrations so the EIN is immediately useful. In Pennsylvania that typically means registering the entity with the Department of State, then setting up your sales tax license, employer withholding, and unemployment accounts through myPATH, all tied to the EIN. Handling these in sequence right after issuance means you can bank, hire, and collect tax without a second round of paperwork later.
