Keep up to date with the latest tax and structuring news with our expert analysis...


We have decades of experience of tax disputes, across the whole of the tax system; for clients from FTSE 100 companies to private individuals; for disputes involving multiple billions down to disputes over tens of thousands; and for all types of disputes, from disputes about international corporate or private structuring, to 'traditional' civil enquiries, to HMRC 'raids' and interviews under caution.

We settle – often on extremely advantageous terms – the vast majority of the disputes we are instructed on. Where settlement is not possible, we litigate, and have successful experience of doing so at all levels, from the First-tier Tribunal to the Court of Justice of the European Union.

We advise individuals and companies of all sizes on disclosures to HMRC in circumstances where there is an ongoing HMRC enquiry, including under Code of Practice 8 and Code of Practice 9, and in making disclosures under the various disclosure facilities.

We advise, alongside accountancy firms of all sizes, on civil settlements with HMRC, and represent regulated individuals in interviews under caution conducted by HMRC – both where the individual has been arrested and where they have not.

We conduct representative litigation before the tax tribunals in respect of investments that HMRC argues to be tax avoidance schemes.

We have considerable experience of cross-border tax issues. We advise companies and individuals in continental EU Member States on UK tax law and cross-border litigation and settlement strategies. We advise in English, French, and German. In addition, through our network of European offices, Fieldfisher advises clients around Europe on tax law and tax disputes in France, Italy, Luxembourg and Spain.
