Pennsylvania S Corporation: The Federal Election, PA Treatment and the 3.07% Pass-Through
Pennsylvania S Corporation: The Federal Election, PA Treatment and the 3.07% Pass-Through
If you search for a “PA S corp” election form, you will not find one. Pennsylvania does not run its own S corporation election. Your S status comes from the federal election, and Pennsylvania follows it. What Pennsylvania controls is how that income is taxed once it reaches you, and that is where the 3.07% personal income tax rate and the Philadelphia rules come in. This guide explains how the pieces fit for a business formed in Pennsylvania, and how an S corp compares with a standard Pennsylvania LLC or corporation.
Informational content, not legal or tax advice. This guide describes general Pennsylvania rules as verified on 2026-10-13. It does not account for your facts. S corporation decisions affect federal payroll tax, owner wages and state withholding, so talk with a qualified CPA before you make the election, and with a licensed Pennsylvania attorney for formation documents and shareholder agreements.
An S corp is a tax election, not a Pennsylvania entity type
An S corporation is a federal tax classification. It is not a separate kind of company. A Pennsylvania business that wants S treatment starts as either a corporation or an LLC, then elects S status with the IRS on Form 2553. A Pennsylvania LLC can make that election, and so can a Pennsylvania business corporation. The state filing you make with the Department of State stays the same, and the S election changes how the income is taxed.
This is why the search phrase “pennsylvania llc vs s corp” is slightly misleading. An LLC and an S corp are not two options at the same level. The real comparison is between a default LLC, which is taxed as a partnership or disregarded entity, and an LLC or corporation that has elected S status. The sections below work through that comparison.
How the federal S election carries into Pennsylvania
Pennsylvania follows the federal S election automatically. For tax years after 2005, there is no separate Pennsylvania election. If the IRS treats your business as an S corporation, Pennsylvania treats it the same way, and you do not file a Pennsylvania form to get that status.
A corporation can opt out of Pennsylvania S status, using Form REV-976. The opt-out has three rules you need to know:
- Every shareholder must sign it. One missing signature is a problem, so collect them all before filing.
- It binds the corporation for 5 years.
- Once opted out, the corporation is no longer treated as an S corporation for Pennsylvania purposes, so the CNIT exemption described below would not apply. Confirm the effect with your CPA before you opt out.
The federal election itself is made with the IRS on Form 2553. The IRS sets the timing and eligibility rules, and those depend on when the tax year begins. Check the IRS instructions or ask your CPA before you rely on a particular effective date, because a late or incorrect federal election affects Pennsylvania treatment too.
What an S corp pays in Pennsylvania
Once the election is in place, the Pennsylvania tax picture looks like this:
| Tax or item | Who pays it | How it applies to an S corp |
|---|---|---|
| Personal Income Tax (PIT) | Shareholders | 3.07% flat rate on pass-through income from the S corp, for resident and nonresident shareholders |
| Corporate Net Income Tax (CNIT) | The corporation | 7.49% for tax years beginning in 2026. S corps are generally exempt, except on built-in gains. |
| Local Earned Income Tax (EIT) | Employees, including shareholder-employees, on wages | Does not reach S corp pass-through income. Shareholder wages remain subject to EIT. |
| Philadelphia BIRT | The business | The business files the Business Income and Receipts Tax return |
| Philadelphia School Income Tax | Resident shareholders | 3.74% on S corp income |
The practical result is that an S corp does not pay CNIT at the entity level on its ordinary profit. Instead, the profit flows through to the shareholders, who report it on their Pennsylvania returns and pay the 3.07% PIT on their share. A C corporation pays 7.49% on its net income at the entity level, and the owners face state personal tax on distributions as well. Your actual result depends on your numbers, so model it with your CPA.
Two details catch people off guard. First, the local EIT that applies to wages does not apply to the pass-through profit, but it still applies to any salary you pay yourself as a shareholder-employee. Second, Philadelphia works differently. The business still files BIRT, and resident shareholders owe the 3.74% School Income Tax on S corp income. Confirm the current BIRT filing details with the City of Philadelphia before you file.
Pennsylvania LLC vs corporation: the state filing differences
The entity you choose sets your state filing obligations, and those differences stay the same whether or not you elect S status. The S election changes tax treatment. It does not change what you file with the state.
| Item | Pennsylvania LLC | Pennsylvania business corporation |
|---|---|---|
| Formation document | Certificate of Organization, Domestic Limited Liability Company (Form DSCB:15-8821), with a Docketing Statement (DSCB:15-134A) | Articles of Incorporation, For Profit, with a Docketing Statement (DSCB:15-134A) |
| Filing fee | $125 | $125 |
| Annual report | $7, due January 1 through September 30 each year | $7, due January 1 through June 30 each year |
| Publication | None | Notice of the filing must be advertised in two newspapers of general circulation, one preferably a legal journal, with proof kept in the corporate minutes |
| Name rules | Must contain “company,” “limited,” or “limited liability company,” or an abbreviation of one of those terms, and may not imply a business corporation | Confirm the name rules with the Department of State before you file |
Both entity types file through Business Filing Services at file.dos.pa.gov. Processing takes about 15 business days, and the Bureau posts current processing times on the same site. Expedited service is available for an added fee, online or in person only.
Pennsylvania does not use registered agents. Instead, your filing must list a registered office with a street address and number. A post office box alone is not accepted. If your business has no physical or mailing address in Pennsylvania, you may contract with a Commercial Registered Office Provider (CROP) under 15 Pa.C.S. section 109 and list the CROP name and county of venue. Listing a CROP without a contract can carry civil and criminal penalties.
Choosing between a default LLC and an S corp in Pennsylvania
This is where the Pennsylvania analysis is often misunderstood. A default pass-through LLC does not pay CNIT either. Its income passes to the owners, who pay the 3.07% PIT on their share. So at the owner level, the Pennsylvania result for a default LLC and for an S corp is largely the same.
The Pennsylvania-specific difference shows up mainly when you compare a corporation that elects S status with one that does not. An LLC taxed as a corporation pays CNIT, and an S corp avoids it, except on built-in gains. The S election is therefore most valuable in Pennsylvania when you are choosing corporate treatment.
For most small owner-operated LLCs, the bigger decision is federal. An S corp lets owner-employees take a salary subject to payroll tax and take the remaining profit as distributions that are not subject to self-employment tax. That structure also brings payroll filings, reasonable compensation questions and separate corporate formalities. Those tradeoffs need a CPA's review, using your actual profit numbers.
Setup steps for a Pennsylvania S corp
- Check and reserve the name. Search the records at file.dos.pa.gov/search/business. A name reservation lasts 120 days and costs $70.
- File the formation document. Submit the Certificate of Organization or Articles of Incorporation online with the Department of State, with the $125 filing fee and a Docketing Statement.
- List a registered office. Use a Pennsylvania street address, or contract with a CROP if you have no Pennsylvania address.
- Get a federal Employer Identification Number from the IRS for the business.
- Make the federal S election on Form 2553, after confirming timing and eligibility with your CPA. Pennsylvania has no separate S election form.
- Register for state taxes on myPATH. The PA-100 was retired in 2022, so registration now happens through myPATH. Register any state tax account you need, including employer withholding if you pay wages. The Department of Revenue lists current options at pa.gov/services/revenue/register-my-business-for-taxes.
- Calendar the annual report. LLCs file by September 30 and corporations file by June 30. The annual report requirement for LLCs began January 1, 2025.
Common mistakes to avoid
- Searching for a Pennsylvania S corp form. The election is federal. Pennsylvania follows it automatically.
- Missing the corporate publication requirement. A corporation must advertise its filing and keep the proof in its minutes. An LLC has no such requirement.
- Using the LLC annual report deadline for a corporation. A corporation's report is due June 30, not September 30.
- Listing a post office box as the registered office. A street address is required.
- Opting out with REV-976 without every shareholder signing. The opt-out will not work as intended, and it binds the corporation for 5 years once it is in effect.
- Assuming local EIT applies to pass-through profit. It applies to wages, not to S corp pass-through income.
No general business license in Pennsylvania
Pennsylvania has no general state business license and no county business licenses. Licensing depends on your activity and location, so check federal, state, county and local requirements separately. Some trades need a state license. For example, home improvement contractors must register with the Pennsylvania Attorney General. The Bureau of Corporations and Charitable Organizations does not issue activity licenses. Your municipality may have its own rules, so check there before you open.

An S corp can be a sound choice in Pennsylvania, but the state rules are only part of the decision. Confirm the federal election, the REV-976 opt-out rules, the Philadelphia filings and your CNIT position with a CPA, and confirm your entity formation details with a Pennsylvania attorney, before you file.
