Tax Reporting, Data & Transformation Internship

CMA CGM is seeking a Tax Reporting, Data & Transformation Apprentice to join its Global Headquarters in Marseille. The role is designed for a student currently pursuing a master's degree in Finance, Accounting, Audit, Tax or a related field, and who has a clear interest in data analytics and digital transformation. The apprenticeship starts in January 2027 and is based on-site in Marseille, offering a chance to work closely with the Group Tax Reporting team on international tax data and reporting work.

You will help collect, clean and reconcile financial and tax data used in the group’s reporting cycles, aiming to produce reliable data sets and clean review files. Alongside hands-on data work, you’ll progressively learn IAS 12 concepts, current and deferred taxes, tax proof reconciliations and ETR analysis, and contribute to practical automation and AI initiatives using Excel and approved tools. This blend of data tasks, international tax exposure and digital transformation will be supported by experienced teammates who review your technical conclusions as you grow.

A day in the life of the tax data apprentice

In this apprenticeship you’ll join the Group Tax Reporting team to collect, clean and structure data from reporting extracts and entity submissions, standardize file formats and ensure source data aligns with reporting schedules. You’ll also conduct completeness and consistency checks, flag gaps, duplicates or unusual movements, and help maintain anomaly trackers that feed proposed corrections for review.

As you build your experience, you’ll support tax reporting cycles by preparing schedules and reconciliations under supervision, and you’ll begin to apply IAS 12 concepts to tax calculations, including simple tax proof reconciliations. You’ll compare basic Effective Tax Rate figures and help organize entity explanations, highlighting items that require deeper investigation while keeping the technical conclusions with more senior team members.

On the digital side, you’ll contribute to practical automation of recurring data tasks using Excel, Power Query and other approved tools, test AI use cases like classifying reporting comments and summarizing reviews, and help maintain dashboards and trackers that monitor data quality and reporting progress. You’ll document test results and limitations, protect confidential data and propose process changes for human review and approval.

Advice for applicants

Lead with the fact you’re pursuing a master’s degree and have data analytics or digital transformation on your radar. Put this right at the top of your resume, including any projects or coursework where you cleaned, organized or analysed datasets.

When you describe your must-have skills, back them up with concrete examples. If you’ve used Excel for data cleaning, include a brief note on a task you completed and the impact it had, and mention any Power Query or Power BI work if you have it.

Prepare to discuss how you would approach the day-to-day tasks this role covers, such as building reliable tax data from extracts, running basic tax reconciliations or identifying anomalies in data. Be ready to walk through a situation where you identified an inconsistency and what steps you took to resolve it.

Have a thoughtful question ready for the interview about how AI use cases are tested against source information or how automation is implemented without losing human oversight in tax reporting. It shows you’ve thought about how the duties translate into real processes.
