About The Internship Programme
Our paid Summer Internship Programme runs for six weeks, four days per week from Monday to Thursday.
The programme gives you the opportunity to experience the tax profession first-hand, working alongside experienced tax professionals and contributing to real client assignments.
Tax is constantly evolving, and the work we undertake helps clients understand and manage their tax affairs while making significant business and commercial decisions.
Throughout your internship, you will be supported by a dedicated buddy and mentor, helping to ensure your experience is productive, engaging and gives you a genuine insight into what a career with K3 Tax Advisory could look like.
What You’ll Experience
Group Induction
You will spend the early part of your first week in London, where you will join interns from across K3 Advisory Group for a general induction and have the opportunity to start building your professional network as part of a group social activity.
You will also spend time with the K3 Tax Advisory team, receiving introductory training. This will prepare you to contribute to real client work throughout your internship.
Your buddy will meet with you to help you set objectives for the programme.
