De minimis exception meaning

What does De minimis exception mean?
In competition and merger control practice, the de minimis exception describes the competition and markets authority’s discretion not to refer a qualifying merger for a phase 2 investigation where the affected UK market is not of sufficient importance to justify the cost and burden of a reference. The discretion is grounded in the Enterprise Act 2002 (section 22) and applied through CMA guidance. In deciding whether to exercise it, the CMA typically considers the size and value of the UK market(s) concerned, the likely scale and duration of any competitive harm, and whether proportionate remedies could address concerns. The exception is used to avoid disproportionate intervention in small markets but is not automatic: the CMA may still refer where harm could be material. Application is consistent across England & Wales, Scotland and Northern Ireland. Separately, “de minimis” is also used to describe the appreciability threshold for anti‑competitive agreements. In Ireland (and before EU institutions), the European commission’s De Minimis Notice guides when agreements fall outside Article 101(1) TFEU for lack of appreciable effect. Post‑Brexit, that EU notice is not binding in the UK, though the concept of appreciability remains relevant under the Chapter I prohibition in the Competition Act 1998.

UK income tax treatment of interest in possession trusts: computation, rates (including trust rates), allowable deductions, and the 2024–25 de minimis income rule

General principles The trustees are, for tax purposes, regarded collectively as a single person, distinct from the individuals who serve as trustees from time to time. An interest in possession (IIP) means a beneficiary has an immediate right to the trust income as it arises. That income belongs to the beneficiary, and the trustees lack authority to retain it, save to meet proper expenses. Where trust income does not fall within the definition of accumulated or discretionary income in section 480 of the Income Tax Act 2007 (ITA 2007), it is treated as the income of ‘other persons’ and taxed at the basic and dividend rates. Ultimately, the income is assessed on the beneficiary at their personal rates, irrespective of when, and even whether, it is actually paid to them. Nevertheless, the trustees are liable to income tax on income arising from trust property because they are the legal owners of that property and thus the persons who receive the income. The way IIP and discretionary trusts are differentiated...

UK investment trusts: definition, HMRC approval criteria and ongoing requirements for favourable tax status

Investment trust An investment trust is a collective investment vehicle structured as a listed, UK tax-resident public limited company. Despite the label, in legal terms an investment trust is a company rather than a trust. The expression stems from a period when these vehicles were established as trusts, but they later converted to limited companies and therefore are no longer trusts in any legal sense. Where HMRC grants approval to an investment trust, it can access certain UK tax advantages. This Practice Note sets out the eligibility criteria that must be met for a fund to obtain approval as an investment trust for UK tax purposes. It also addresses the continuing requirements that must be satisfied in every accounting period for which the vehicle holds that approval...
