Onshore
Onshore (formerly SPRX) is changing how companies claim tax incentives.
Traditional firms rely on interviews, retroactive documentation, and billable hours. Onshore applies AI at the point of substantiation, providing documentation tied directly to source data and pairing it with expert review.
The result is defensible, audit-ready work delivered in weeks, not quarters.
We help companies claim R&D Tax Credits, 179D Deductions, and Cost Segregation with proof, not process.
500+ companies have trusted Onshore to identify and defend more than $600M in incentives.
We operate with clear accountability and high standards. Outcomes matter more than activity.
