From IRC research to return preparation, three key AI applications revolutionize how tax professionals work, with adoption rates exceeding 50% across all categories.
Tax research (69% of professionals)

Tax return preparation and advisory (55% of professionals each)
AI assistance in tax return preparation focuses on specific areas under U.S. tax law. It can complete data validation, error detection, compliance checking, and more. U.S. firms achieve significant time savings in multiple areas while maintaining professional oversight.
