While some routine elements like billing and tax return preparation are increasingly automatable, much of the role involves complex judgment, client interaction, and bespoke advisory work that require human expertise. AI tools can significantly augment research, documentation, and process optimization, but key tasks such as mentoring, client relationship management, and technical tax advisory remain resistant to full automation.
