• Preparation and review of corporation tax computations
• Managing key return, payment and client deadlines
• Liaising directly with clients and HMRC

• Strong internal progression, mentoring and structured development at Assistant Manager, Senior Manager and Director level
• Scope to develop a specialist area over time, whether that is capital allowances, R&D, international tax, employee rewards or another area of interest
• A collaborative office culture with excellent staff retention and a genuine one-team feel
• Easy access from High Wycombe station, just a short walk from the office
• 25 days' annual leave, pension, life assurance, flexible benefits, profit share and discretionary bonus
