About SPRX
SPRX is a technology company that is changing the tax consulting industry. We have developed artificial intelligence software that automates many of the tasks performed by tax consultants. This gets much more exciting when you consider that tax consultants earn more than $10 Billion in fees each year. That's a market worth transforming!
What is tax consulting? Good question. Tax consultants are tax experts that analyze one or two numbers that go on a company's tax return. For example, the R&D tax credit. The rules for the R&D tax credit are very complex and most accountants do not have the expertise to compute the credit. So a company will hire a tax expert to compute the R&D tax credit for the company. That's tax consulting.
