Tax investigations

Tax investigations can be stressful, costly and time consuming, and with the number of investigations on the rise, it pays to have the best advice.

Mazars' National Tax Investigations Group consists of specialists in all areas of taxation as well as the National Minimum Wage. Our team deals with matters ranging from individual tax disputes, to large, complex and high profile cases. We help individuals, companies and trusts selected for investigation - ranging from an aspect inquiry through cases of suspected serious fraud under Code of Practice 9 to criminal investigations.

Our team has many years of experience working in HM Revenue and Customs and private practice and can guide you or your business or company through the investigation process quickly and efficiently. If you are an employer, we can also review your systems and records so you can be confident in them, if approached by HMRC's Employer Compliance division.
