Forvis Mazars is a leading global professional services network providing audit & assurance, tax, and advisory services. Forvis Mazars in the UK spans 14 offices across the UK and has over 3,400 professionals, with 190 partners. We have a clear purpose and a shared commitment to shape a better future. You'll join a collaborative and inclusive team where you're supported to grow your skills, explore new opportunities, and contribute from day one.

You'll work with a diverse client base, develop meaningful connections, and gain experience that extends beyond your local team. Together, we grow, belong and impact.

Our AOS Rotational Programme offers early careers apprentices the opportunity to gain hands‑on experience across a range of accounting and outsourcing services. You'll rotate through specialist teams, working with clients from sectors including financial services, healthcare, large international groups, and privately owned businesses. You'll be part of a strong team operating across five UK offices, with access to a wider network of over 300 professionals in our Accounting and Outsourcing service line.

This programme is designed to build your technical expertise, client relationship skills, and understanding of global finance operations.

As an apprentice, you'll rotate through departments listed below, spending a minimum of 12 months in each department across the 4 year programme. This rotation gives you broad exposure to different areas of the AOS service line. Once you complete your apprenticeship, you'll have the opportunity to specialise in a department based on your preference and business need at the time.

Please note that not all departments are based in every office. You'll receive more information about office‑specific options if you progress to the later stages of the selection process.

• Accounting, Outsourcing & Advisory:
  Working on outsourced finance function delivery, you will gain experience of day‑to‑day accounting, the production of management information, calculation of VAT returns, and advisory support including forecasting and finance function reviews. In addition, supporting with accounting compliance activities you will learn how to prepare statutory financial statements. You'll be a key contact for your client portfolio, and will work across large mid‑market clients including our specialist financial services sector team.
• SME Accounting & Outsourcing:
  Our SME team work very differently, meeting the needs of our smaller clients who often value the wide range of Forvis Mazars services being provided through a single contact point. Work here includes finance function outsourcing and accounting compliance, but you will also gain experience of personal and corporate tax. This team work closely to provide a solution for the client and the owner as one, and so collaborate closely with our financial planning team.
  
  Our target SME clients are fast growth, entrepreneurial businesses and we also have a dedicated team specialising in the Healthcare sector.
• International Accounting Services:
  Work with global clients to deliver day‑to‑day and year‑end accounting solutions. You'll help coordinate multi‑country engagements and may provide interim support where clients face internal skill shortages. While the services here are similar to those in other parts of AOS, the ability to think globally and to support our clients with multi‑country assignments is our real specialist skill.
