Who Qualifies for Pennsylvania R&D Tax Credits?

Pennsylvania-Specific Benefits
Small Business Rate Advantage
Businesses with net book value of assets of $5 million or less qualify for the enhanced 20% rate. A balance sheet must be submitted to document eligibility. A dedicated $12 million annual set-aside is reserved exclusively for small business applicants within the $60 million statewide cap.
Selling Unused Credits for Immediate Cash
Approved credit recipients who cannot fully use their award against their own tax liability may apply to sell the unused portion to another taxpayer. Sales must be completed by June 1 following the award year, and sellers have historically retained approximately 92-93 cents on the dollar.
Federal R&D Tax Credit for Pennsylvania Companies
Pennsylvania businesses can claim the federal R&D credit in addition to state benefits for qualifying research conducted anywhere in the U.S. The federal credit can be calculated using the Regular Research Credit (RRC), which compares current spending to a historical baseline, or the Alternative Simplified Credit (ASC), a streamlined three-year average method often preferred by newer claimants.
Qualified small businesses can apply the federal credit against payroll taxes up to $500,000 per year, providing immediate cash flow benefits for Pennsylvania biotech startups and early-stage software companies. Businesses should also evaluate the Section 280C election, which affects how R&D deductions interact with the federal credit calculation.

Saving Money, Spurring Innovation
Every day, companies nationwide further the mission of innovation with new products, processes and initiatives that change the landscape of how we do business. But innovation takes funding, and with that comes a vicious cycle: You need money to grow your business and develop your products and services… but you also need to do those same things to bring money in.
That’s why R&D tax credits were established. Designed to encourage companies like yours to invest in the innovation, creation and improvement of products or processes, R&D tax credits can offset some of the costs associated with research and development — fueling growth and technological advancement.
Pitfalls Pennsylvania Companies Should Avoid
Can You Claim Credits for Previous Years in Pennsylvania?
Yes. Many Pennsylvania companies have unclaimed R&D credits from prior years that can still be recovered through amended applications or returns, subject to the standard statute of limitations from the original return filing date. Historical lookback credits may be subject to proration, and award amounts will depend on the caps and applicant pool for the applicable year.
A professional review can identify qualifying activities across open years, ensure the small business rate is being captured, and build the documentation infrastructure needed to support ongoing annual applications.
