Updated Sanctions Guidance published

The Taxation Disciplinary Board (TDB) published substantially revised Indicative Sanctions Guidance (ISG) in December 2020. The document sets out the range of sanctions that are available to Disciplinary Tribunals with indications of how these may be applied to various situations.
The TDB is committed to reviewing the ISG annually and publishing revised versions as needed. Following a review in late 2021, which drew on the experience in using the new ISG since its introduction together with input from stakeholders, a revised version of the ISG was published in January 2022 and is effective from that date. The document may be found here.
