Audit, litigation and criminal tax lawyers

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. Our specialist audit, litigation and criminal tax lawyers will 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 domestic or European administrative, judicial or criminal bodies.

Our expert lawyers work in close collaboration with the firm’s other teams specialising in transfer pricing, company law or competition law, amongst others. Whenever they need to, they can also draw on the CMS network and our international partners, so that you benefit from a global technical expertise. We are there to help you in advance of any audit procedures, to ensure your practices comply with the regulations in force, throughout the audit to facilitate your relationship with the tax authorities, and once the audit is complete, we will assist you with any litigation and settle any disputes you have, including any criminal tax matters. Our know-how, nurtured by more than 90 years’ practice, combines with an in-depth understanding of your issues, and of changes in the legal landscape, to provide you with the best and most secure safeguards for all relevant concerns.
