732.This section enables the Treasury to make regulations prescribing the procedure for giving notices and other documents under the Act.  The power covers any such provision in the Act, regardless of its precise wording, and includes provisions about giving directions or imposing requirements.
733.In particular, the regulations may specify how a document may be given, the address to which it should be sent, and whether the document or notice may be sent electronically.  They may also specify the date and time a document  is to be regarded as having been served (this may be important, for example, where a time limit begins to run from that date).  The regulations may also make particular provision for cases where the person to whom the document is being sent is not an individual (for example, in the case of a limited company or partnership) or is outside the United Kingdom.  The precise arrangements required under the regulations may vary depending on the nature of the document in question.
