What technology are used in EY tax?

It would depend on your sub-service line I would say! I can speak from a perspective of PAS tax, where technology tools help us implement AI solutions or systems to help us (for example) quickly identify relevant tax legislations that are specific to the project on hand - basically I would say technology help us work more efficiently.

Sounds great! May I ask are there any drawbacks or risks of using technology in tax? And how should we take care of it in work please?
