What Onshore does
Onshore uses AI to prepare corporate R&D tax credits. With our technology, anyone can prepare an R&D Tax Credit accurately and fast. To provide some background, the R&D Credit is often cited as the most complex and audited tax credit in the United States. With that in mind, we set out to create software to achieve two primary objectives: 1. Ensure that any credit computed with our software is exactly what the IRS is asking for in terms of quality. 2. Democratize the ability to perform high quality R&D Credit studies extremely fast.
