Tolley+ in practice
Real workflows from practitioners across UK firms — research, advisory and drafting.
Corporate Tax
Find answers faster
A corporate tax manager preparing a group restructure needed the latest legislation, related HMRC manuals and recent tribunal decisions — without leafing through ten sources.
A single Starting Point gave them a topic overview, the underpinning legislation, linked commentary and recent cases — surfaced as one structured view.
Personal Tax
Worked examples that save hours
A practitioner advising on a complex IHT planning scenario opened a worked example template and dropped in the client's figures.
The template auto-applied the relevant rules and references, turning a multi-hour exercise into a confident draft in minutes.
VAT
Right treatment, first time
A junior adviser unsure of the partial exemption treatment for a mixed-use supply turned to Smart Lists rather than guessing.
The Smart List surfaced the correct treatment supported by legislation and HMRC references — letting them delegate confidently and review fast.
