Research and Development Tax Credit
Publication revised September 24, 2026. Sourcebook page 232.
Credit amount / calculation
Percentage of Pennsylvania qualified research expenses over base; annual statewide allocation and small-business set-aside apply.
Business fit and eligible activity
Qualified Pennsylvania research can generate an annually allocated credit. Qualified research activity. Ordinary production, routine quality control and an equipment purchase alone do not qualify.
Eligibility and practical use
A wood-products company can miss this credit by assuming that "research" means white coats and laboratories. In practice, qualifying work can arise in process engineering, product development, automation, drying, recovery, and software. A logging company has a narrower path, but equipment-control, software, or process-development work can sometimes qualify if it satisfies the same technical tests. This program also has an advance procedural step, so the technical work should not begin on the assumption that a later application will cure the timing issue.
Illustrative business benefit
Use-of-credit illustration, not an estimated award: assume the agency or completed tax form establishes a $1,000 credit for the qualifying activity described above. If sufficient eligible tax is due, a $1,000 credit available for current use reduces that tax by $1,000. If annual limits allow only $600, that is this year's saving; the other $400 survives only if the carryforward or transfer rules permit. Obtain the actual program calculation before estimating a project benefit.
Timing / first action
Check application or certification requirements before incurring the qualifying expense or beginning the qualifying activity.
