Ohio R&D Tax Credit Summary


The Ohio Research and Development Investment Tax Credit, which is authorized within Section 5751.51 of the Ohio Revised Code, is a nonrefundable credit against the Commercial Activity Tax (CAT) liability. It is available annually and is based upon QREs in Ohio as defined in I.R.C. Section 41. To receive an Ohio R&D tax credit, the taxpayer must be allowed a research credit for the taxable year against federal income tax for qualified research expenses under I.R.C. Section 41.

Ohio’s definition of research and development expense is the same as the federal and generally includes in-house expenses paid for wages, supplies and 65 percent of contract expenses paid to outside research firms.
