The Treasury amended the MLRs 2017 to introduce enhanced due diligence for cryptoasset correspondent relationships, update trust registration rules, create provisions for insolvent bank customers, substitute monetary thresholds from Euros to Sterling, and modify change of control rules for cryptoasset businesses.

These Regulations, enacted by HM Treasury, substantially amend the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 (MLRs) to strengthen anti-money laundering and counter-terrorist financing regimes, notably by implementing enhanced due diligence requirements for cryptoasset correspondent relationships and addressing specific areas like insolvent bank customers and trust registration.

Key changes include the introduction of new duties for cryptoasset businesses dealing with overseas providers, clarification of Customer Due Diligence (CDD) for pooled accounts, substitution of 'high-risk third country' with 'FATF call for action country,' conversion of various monetary thresholds from Euros to Sterling, and amendments to trust registration rules concerning pre-2020 UK land acquisitions and the exclusion criteria for certain trusts.

Furthermore, the rules governing changes in control over registered cryptoasset businesses are modified to align with the evolving future regulatory framework under FSMA, with some provisions taking effect later in 2027.

Government enacted miscellaneous amendments to existing customs regulations concerning bulk declarations, carnet usage, import duty interest calculation, and approval conditions for storage facilities, effective June 30th, 2026.

These Regulations, made by HM Revenue and Customs and the Treasury, introduce several amendments to existing UK customs legislation enacted following the EU exit, primarily concerning bulk Customs declarations, the acceptance of both paper and electronic customs carnets, the calculation of interest on late import duty liabilities, and providing HMRC with powers to require necessary examination or storage functions to be conducted at approved 'off-site facilities'.

The rules come into force on June 30th, 2026, with specific provisions taking effect retrospectively or immediately upon that date.

A new Article 465A was inserted into the retained Capital Requirements Regulation (EU No 575/2013) to mandate a transitional period, running from January 1st to December 31st, 2027, exempting credit institutions and certain investment firms from applying specific new PRA market risk model rules.

These Statutory Instruments, made by the Treasury and coming into force on December 30th, 2026, insert a new Article 465A into the retained Capital Requirements Regulation (Regulation (EU) No 575/2013) to establish a transitional provision for calculating market risk capital requirements.

This provision mandates that credit institutions and Part 4A investment firms must suspend the application of specific, newly introduced PRA rules (concerning internal models and related requirements) between January 1st, 2027, and December 31st, 2027, allowing them time to transition their methodologies before the revocation of the relevant EU-derived provisions takes full effect, with the Treasury retaining the power to extend this period.

Incorporated updated financial definitions and regulatory activities into UK law to replace revoked EU-derived regulations effective 1 January 2027.

These Regulations amend the Financial Services and Markets Act 2000, the Banking Act 2009, and various pieces of secondary legislation to restate and update definitions relevant to credit institutions and investment firms.

The instrument establishes new legal definitions for terms including 'Part 4A investment firm', 'financial holding company', and 'own funds' to replace those previously derived from EU law.

It applies to financial regulators (the FCA and PRA), UK banks, building societies, investment firms, and their parent undertakings, effectively moving technical definitions from the revoked Capital Requirements Regulation into the UK domestic statute book.

The Regulations exempted income tax for accredited, non-UK resident individuals performing activities connected with the Glasgow 2026 Commonwealth Games during a defined operational period.

These Regulations, enacted by HM Treasury under the Finance Act 2014, establish an income tax exemption for individuals accredited by the organizer of the Glasgow 2026 Commonwealth Games for income earned while performing activities connected with the Games between July 16th and August 4th, 2026, provided the individual meets specific non-UK residence criteria for the relevant tax year or period.

The Regulations amended the Customs (Northern Ireland) (EU Exit) Regulations 2020 to correct errors, introduce 'interchangeable goods' provisions under Chapter 6 for repayment/remission claims, and link Chapter 5 relief to Chapter 6 claims, while inserting a 'fit and proper person' test for certain claims.

The Customs (Northern Ireland) (EU Exit) (Amendment) Regulations 2026 modify the existing 2020 Regulations concerning customs duties in Northern Ireland post-EU exit by correcting minor errors across several chapters and introducing two key substantive changes: establishing a linkage for claims between the Chapter 5 relief scheme and the Chapter 6 repayment/remission scheme, and introducing a mechanism for 'interchangeable goods' claims where identifying specific goods is impracticable due to mixing.

The commencement date for the Customs (Northern Ireland) (EU Exit) (Amendment) Regulations 2026 was officially changed from 20th April 2026 to 25th May 2026.

These Regulations, officially titled The Customs (Northern Ireland) (EU Exit) (Amendment) (No. 2) Regulations 2026, introduce a technical amendment to delay the enforcement date of a preceding Statutory Instrument, specifically S.I. 2026/393.

The Treasury exercised powers under the Taxation (Cross-border Trade) Act 2018 to move the commencement date for specific customs amendments in Northern Ireland from April 20th, 2026, to May 25th, 2026.

The appointed day for the commencement of Finance Act 2021 penalties for failures by digitally obligated persons regarding income tax and capital gains tax returns and payments was set to 1st April 2026.

These Regulations, made by HM Treasury, appoint 1st April 2026 as the commencement date for specific penalty provisions within Schedules 24, 25, 26, and 27 of the Finance Act 2021 concerning income tax and capital gains tax.

The appointed day applies these penalties—covering failures to make returns, deliberate withholding of information, and failure to pay tax—specifically to 'digitally obligated persons' concerning tax matters related to the 2026-27 tax year and beyond, excluding trustees and partnerships.
