How to Get an EIN in Pennsylvania for Your LLC

Here’s how to get an EIN in Pennsylvania as of 2026: you apply directly with the IRS, it’s free, and the online application returns your number the same day. The state doesn’t issue EINs at all. What’s genuinely local is everything that comes after, once you form a Pennsylvania LLC and start registering tax accounts through the Department of Revenue’s myPATH portal.

Does Your Pennsylvania LLC Need an EIN?

Not every Pennsylvania LLC is legally required to have an EIN, but most need one fast. Three things settle it: whether the LLC has more than one member, whether it hires anyone, and how it’s taxed.

A single-member limited liability company with no employees is a disregarded entity for federal tax, so the IRS doesn’t strictly require it to hold an EIN. Get one anyway. Banks ask for it, and it keeps your Social Security number off vendor forms.

Multi-member LLCs don’t get that choice; they need an EIN from the start. A clear Pennsylvania operating agreement helps everyone agree on who the responsible party will be before that name gets locked onto the federal record.

How to Apply for a Pennsylvania EIN on IRS.gov

Most Pennsylvania owners finish the online application in one short session, as long as the LLC is already approved. Here’s the sequence that keeps you from having to refile.

1. Confirm your LLC is approved: the name on your EIN has to match the Department of State record, so check how long Pennsylvania LLC approval takes before you start.
2. Open the IRS EIN Assistant: it runs Monday through Friday, 6 a.m. to 1 a.m. ET, Saturday 6 a.m. to 9 p.m., and Sunday 6 p.m. to midnight.
3. Pick the right entity type: this is the screen that trips people up; a standard LLC isn’t a corporation unless you’ve already filed to be taxed as one.
4. Enter the legal name and any trade name: the legal name matches your Certificate of Organization, and a DBA goes in the trade-name field.
5. Name the responsible party: a natural person with an SSN or ITIN, never the LLC itself.
6. Submit and save the CP 575 right away: the IRS issues this confirmation notice only once, so download the PDF as soon as it appears. If you lose it later, a 147C letter is the official replacement.

Pennsylvania EIN Approval: Save Your CP 575 Before myPATH Registrations

Once the IRS approves your Pennsylvania LLC’s EIN, the confirmation you need to save is the CP 575. This is the official IRS EIN assignment notice, and it is the letter banks, payroll providers, and tax platforms may ask for before they accept the number.

What it looks like

The CP 575 shows your LLC’s legal name, mailing address, and federal EIN. For a Pennsylvania LLC, compare that name against your Certificate of Organization before you use the EIN in myPATH, payroll setup, bank paperwork, or Pennsylvania tax registrations.

• Do not confuse it with your Department of State entity number. That number belongs to your Pennsylvania formation record, while the EIN belongs to the IRS.
• Do not treat it as your Pennsylvania sales tax or withholding account. Those registrations happen separately through myPATH when your LLC needs them.
• Keep it separate from your UC Employer Account Number. Pennsylvania unemployment registration and later UC wage reporting use state systems, not the CP 575 itself.

Save the CP 575 immediately. The IRS issues this confirmation notice only once through the online EIN application. If you lose it later, you will need to request an EIN verification letter, commonly called a 147C letter, from the IRS.

Three other methods exist, but they’re slower. Faxing Form SS-4 returns the EIN in about 4 business days, and mailing it takes roughly 4 weeks.

If your principal place of business sits outside the United States, you can call the IRS international line at 267-941-1099, weekdays from 6 a.m. to 11 p.m. ET. That international line isn’t a backdoor for domestic applicants who simply don’t have an SSN yet.

Two last guardrails. The Internal Revenue Service issues one EIN per responsible party per day, and the online tool times out after 15 minutes of inactivity. Have your details ready before you log in. The catch with paid EIN services is that there’s no catch; the EIN is free, and a fee buys nothing the IRS doesn’t already do at no cost.

Match Your EIN to Your Pennsylvania Certificate of Organization

Gather a short list before you open the application, because the online session won’t save your progress. None of it’s hard to find once the LLC exists.

• Approved legal name: exactly as it reads on your Certificate of Organization, matched against a Pennsylvania business name search.
• Department of State entity number: assigned when your formation is approved.
• Responsible party and TIN: a person’s name with an SSN or ITIN.
• Federal tax classification: disregarded entity, partnership, or corporation.
• Business mailing address: where the IRS sends notices.

Sequence is the whole game here. Forming first, then applying, keeps your CP 575 name lined up with the state record, which banks and payroll providers check line by line. If you’re deciding whether to file it yourself, Pennsylvania LLC filing costs start at the $125 Certificate of Organization fee.

EIN vs Your Pennsylvania Sales Tax License and Withholding Numbers

Pennsylvania doesn’t fold its state taxes into one tidy number, and that’s the detail owners miss most. The EIN identifies the business to the IRS; separate Pennsylvania accounts identify it to state and local agencies.

Read that table as a map, not a to-do list. A freelance designer with no staff and no taxable sales might only ever touch the federal EIN. A retailer with a storefront and a payroll could be holding four or five of these numbers at once, each from a different office.

Registering Pennsylvania Tax Accounts on myPATH After Your EIN

Once the EIN lands, the Pennsylvania layer begins. Almost all of it runs through myPATH, the Department of Revenue’s portal, using the Pennsylvania Online Business Tax Registration service. Older guides still say “file the PA-100,” but that registration moved into myPATH, so don’t burn time hunting for the old form.

Employer Withholding at 3.07 Percent

If your LLC pays wages, it registers for an Employer Withholding account and withholds Pennsylvania personal income tax at a flat 3.07 percent. The account opens inside myPATH, and your EIN is required to finish it.

Sales, Use and Hotel Occupancy Tax License

Selling taxable goods or services means registering for a Sales, Use and Hotel Occupancy Tax License. The base rate is 6 percent, with Allegheny County adding 1 percent and Philadelphia adding 2 percent. Remote sellers cross Pennsylvania’s economic nexus once annual sales here reach $100,000.

Unemployment Compensation and the UCMS Split

Hiring also triggers an Unemployment Compensation account with the Department of Labor and Industry, which assigns an Employer Account Number. You register through myPATH, but every quarterly wage and tax report after that happens in a separate system called UCMS. They’re two portals doing two jobs, and owners mix them up all the time.

Local EIT and LST: The Step Competitors Skip

This is where Pennsylvania gets genuinely local. Employers with a worksite in the state withhold Local Earned Income Tax and the Local Services Tax, using PSD codes to send the money to the right municipality. New hires fill out a Residency Certification Form, and you may need to register with the local tax collector for an account.

If You Operate in Philadelphia

Philadelphia runs its own stack on top of the state’s. A business doing work in the city needs a Philadelphia Tax Identification Number, known as a PHTIN, plus a Commercial Activity License before it operates there. Both cost nothing, and the PHTIN is what ties you to city taxes like the Business Income and Receipts Tax.

Two state housekeeping items round this out. Your LLC files a Pennsylvania annual report each year for $7, and that’s separate from the federal BOI report some LLCs owe FinCEN.

A dependable Pennsylvania registered agent keeps both that report and your state notices from sliding past their deadlines, including the September 30 annual-report cutoff.

Pennsylvania EIN Mistakes: PA-100, Franchise Tax, and Multiple IDs

A handful of errors show up again and again with Pennsylvania LLCs, and most cost time rather than money. Catching them early is the cheapest fix there is.

• Assuming one “PA tax ID”: there’s no single state number; the EIN, sales tax license, and UC account are all separate.
• Searching for “PA-100”: the form’s retired, and the registration now lives entirely in myPATH.
• Treating the EIN as a state registration: it doesn’t open your withholding, sales tax, or UC accounts on its own.
• Expecting a Pennsylvania franchise tax: the Capital Stock and Foreign Franchise Tax ended for tax years starting in 2016, so ordinary LLCs don’t owe it.
• Naming a nominee as responsible party: the IRS wants a natural person in control, not a formation agent standing in.

If you’d rather not handle formation alone, it’s worth comparing Pennsylvania LLC formation services before you pay anyone, since the EIN itself should never appear as a line item.

Lost Your EIN or Restructuring Your Pennsylvania LLC?

Misplacing an EIN happens constantly, and the number never expires, so it’s almost always recoverable. Start with the CP 575, an old federal tax return, or your business bank records.

If none of those turn it up, request a 147C verification letter from the IRS. Our guide on how to find your EIN covers every other place the number shows up. Your Pennsylvania account numbers live in myPATH and UCMS, separate from that federal letter.

Some changes need a brand-new EIN and others don’t. Converting a sole proprietorship into an LLC, or moving from single-member to multi-member, requires a new number. A simple name or address change doesn’t; you handle those with IRS Form 8822-B or Form 8832 instead.
