These Regulations amend the retained EU law known as the EMIR Regulation to establish a permanent regime for exempting intragroup over-the-counter (OTC) derivative contracts from clearing and risk-management requirements.

They expand the definition of intragroup transactions to include those involving entities established in any jurisdiction, provided they are part of the same consolidated group and subject to centralized risk procedures.

It removes tax relief on interest or alternative finance returns generated by cash deposits held within stocks and shares or innovative finance ISA components, requiring account managers to pay a flat-rate charge to HMRC at the savings basic rate.

Additionally, the regulations update the definition of money market funds and prohibit stocks and shares ISAs from consisting entirely of such funds, while revising transfer rules to restrict under-65s from moving funds into cash accounts in certain circumstances.

This change applies to taxpayers across the United Kingdom who are subject to penalties for deliberate tax inaccuracies or failures to notify.
