S Corporation Tax

Pennsylvania recognizes the federal S-election, and Pennsylvania S corporations are not required to pay tax to the state. However, individual S corporation shareholders will owe tax on their share of the corporation’s income. S corporations file PA-20S/PA-65 S corporation/partnership information return.

LLC/Partnership Tax

LLCs and partnerships are not required to pay income tax to Pennsylvania. Instead, income from the business is distributed to individual LLC members or partners, who then pay Pennsylvania income tax on that amount with their personal return. Partnerships file PA-20S/PA-65 S corporation/partnership information return.

Composite Tax

Pennsylvania s corporations, partnerships and LLC’s may file a composite return on behalf of their qualified nonresident individual owners who elect to be included in the composite filing. This composite income tax is filed on form PA-40NRC - Nonresident Consolidated Income Tax Return. This form can be found here:

Penalties 

Failure to file a pass through entity return may result in a $250 penalty. 

Individuals who do not file or file a late return may be subject to a 5% penalty on the unpaid balance due per month, up to a maximum of 25%. 

PA law also imposes a 5% underpayment penalty. If you do not report taxable income you may face an additional penalty up to 25% of the tax due on unreported income. 

Additional Information

If your business was formed or is located in another state, but generates income in Pennsylvania, it may be subject to Pennsylvania taxes. The rules for taxation of multistate businesses, including what constitutes nexus with a state for the purpose of various taxes, are complicated. If you run such a business, you should consult with a tax professional.
