What Is an S Corp in Pennsylvania?

An S Corp in Pennsylvania is a standard corporation (C Corp) or limited liability company (LLC) that has elected to be taxed under Subchapter S of the Internal Revenue Code. This designation allows corporate income, losses, deductions, and credits to pass through to shareholders without being taxed at the corporate level.

S Corporations are often chosen for their:

• Pass-through taxation
• Self-employment tax savings
• Strong liability protection
• Flexible ownership structure

To qualify for S Corporation status, businesses must meet IRS and Pennsylvania Department of Revenue requirements.

Advantages of Forming an S Corporation in PA

Why choose an S Corporation in PA over a traditional C Corp or LLC? Here are the key benefits:

1. Pass-Through Taxation

Profits and losses are passed directly to shareholders, avoiding the double taxation associated with C Corporations.

2. Payroll Tax Savings

Unlike LLCs, S Corp owners can pay themselves a “reasonable salary” and receive additional income as dividends, which are not subject to self-employment taxes.

3. Legal Protection

An S Corp in Pennsylvania shields personal assets from corporate debts and liabilities, provided corporate formalities are followed.

4. Business Credibility

Using a formal business structure increases credibility with investors, vendors, and partners.

Step-by-Step: How to Set Up an S Corp in Pennsylvania

Ready to make the switch? Here’s how to form an S Corp in PA in 2025:

Step 1: Choose Your Business Name

Ensure your business name is unique and complies with Pennsylvania naming guidelines. You can perform a name availability check via the Pennsylvania Department of State website.

Step 2: Designate a Registered Office

Pennsylvania requires you to list a registered office address where legal documents can be delivered. You may use a commercial registered office provider (CROP) or a physical location within the state.

Note: A commercial registered office provider (CROP) is a third-party provider authorized to serve as your business’s registered office in Pennsylvania.

Step 3: File the Articles of Incorporation (For C Corp) or Certificate of Organization (For LLC)

Depending on your entity type, you’ll need to file one of the following:

• Articles of Incorporation (Form DSCB:15-1306) – For C Corps
• Certificate of Organization (Form DSCB:15-8821) – For LLCs

Include the $125 state filing fee and submit via the Pennsylvania Business One-Stop Hub.

Step 4: Obtain an EIN (Employer Identification Number)

You’ll need an EIN from the IRS to file federal taxes, open a business bank account, and process payroll.

Step 5: File IRS Form 2553

This is the critical step to become an S Corp in PA. File Form 2553 with the IRS to elect S Corporation status. The form must be submitted:

• Form 2553 must be filed within 2 months and 15 days after the beginning of the tax year, or by March 15 for calendar-year taxpayers. Late elections may be accepted with reasonable cause.

Step 6: File PA-20S/PA-65 Information Return with the Department of Revenue

All Pennsylvania S Corps must file the PA-20S/PA-65 form annually, even if no business was conducted during the year.

What to Do to Set Up an S Corp in Pennsylvania

Pennsylvania S Corp Filing Requirements (2025)

Once formed, your S Corp has ongoing obligations to maintain good standing in Pennsylvania. Below are the Pennsylvania S Corp filing requirements:

Annual Requirements

• Federal Form 1120-S – Annual federal tax return for S Corporations
• PA-20S/PA-65 – Pennsylvania Information Return
• Shareholder Statements (Schedule RK-1/NK-1) – Provided to each shareholder
• Annual Business License Renewals (check with your local municipality, especially if operating in Philadelphia or Pittsburgh).

While Pennsylvania does not require a statewide annual business license, local municipalities (like Philadelphia or Pittsburgh) may impose their own licensing or business privilege tax requirements.

Other Considerations

• Employer Withholding Tax – For employee payroll
• Sales and Use Tax License – If selling taxable goods or services
• City-Specific Taxes – Localities like Philadelphia may impose additional taxes

Failure to comply with these S Corp obligations in Pennsylvania may result in fines, penalties, or revocation of your corporate status.

S Corp in PA: State vs. Federal Tax Implications

Federal Tax

At the federal level, S Corps are pass-through entities. The business does not pay income tax. Instead, profits are distributed to shareholders and reported on their personal tax returns.

Pennsylvania State Tax

Pennsylvania also recognizes S Corporation status, but there are nuances:

• No corporate net income tax (CNIT) is assessed to S Corps
• Capital Stock/Franchise Tax was fully phased out as of January 1, 2016, so Pennsylvania S Corps are no longer subject to this tax
• Shareholders still pay personal income tax on their share of the company’s income
• Pennsylvania has a flat personal income tax rate of 3.07%

Common Mistakes When Filing as an S Corp in Pennsylvania

• Not issuing shareholder statements (RK-1/NK-1)
• Improper payroll setup for shareholder-employees

To remain compliant, businesses must stay current on both federal and Pennsylvania S Corp filing requirements.

Convert an LLC to an S Corp in Pennsylvania

Already operating as an LLC but want the tax advantages of an S Corporation? Here’s how to transition:

1. Verify IRS Eligibility

To be taxed as an S Corp, your LLC must:

• Be a domestic entity
• Have 100 or fewer shareholders (all individuals or qualifying trusts)
• Issue only one class of stock

2. Elect S Corp Status

File Form 2553 with the IRS. You don’t need to convert to a C Corporation to be treated as an S Corp for tax purposes the LLC retains its legal structure while being taxed differently.

3. Notify the Pennsylvania Department of Revenue

Your business must also complete the REV-976 form to ensure that Pennsylvania recognizes your new tax status.

Is an S Corporation in PA Right for Your Business?

While an S Corp isn’t ideal for every company, it works well for businesses that:

• Generate consistent profits
• Want to minimize self-employment taxes
• Are looking to attract investors
• Have multiple owners or shareholders
• Want more formal corporate structure and legitimacy

If your Pennsylvania-based business fits this profile, the S Corp could be a strategic path forward in 2025.
