Tax audits and litigation

Our expertise for your strategic operations

Key contacts

Tax audits that are increasingly frequent and increasingly strict, even in their cross-border aspects, the proliferation of tax standards, the ever-growing numbers of fiscal and regulatory obligations and the increasingly judicial nature of tax procedures pose greater risks to companies, entrepreneurs and private individuals.

Front line guidance before French and European jurisdictions

Our specialist lawyers in tax audits and litigation offer you advice and assistance on preparing for an audit as well as with every step of your dealings with the tax authorities, including any appearance you may have to make before any administrative or judicial bodies. They work in close collaboration with the firm’s other teams specialising in transfer pricing, company law and competition law. Where necessary, they also draw on the CMS organisation and our international partners to provide you with comprehensive technical expertise. They intervene upstream of audit procedures to ensure that your practices comply with current regulations, during the audit to assist you in your dealings with the tax authorities, and downstream to assist you in your litigation and dispute resolution.

An expertise that has been built over time and that is constantly enriched

Our know-how, nurtured by more than 100 years’ practice, combines with an in-depth understanding of your challenges and developments in the legal landscape, to provide you with the best and most secure safeguards.
