The Digital Communications and Contact Details Regulations 2026

Published: Tue 14th Jul 26

Established a framework for HMRC to use electronic communications by default for specified tax matters and mandated the provision of digital contact details by service users.

These Regulations authorize the Commissioners for His Majesty's Revenue and Customs (HMRC) to designate specific taxation matters as 'default digital matters,' enabling the agency to use electronic communications with taxpayers by default unless they formally opt out.

The instrument requires individuals using HMRC online services for these matters to provide and maintain accurate digital contact details, such as email addresses.

It applies to any person or entity interacting with HMRC's digital services and empowers the Commissioners to suspend service access for those who fail to provide required contact information without a reasonable excuse.

Arguments For

The instrument states that it enables the Commissioners for His Majesty's Revenue and Customs (HMRC) to designate specific taxation matters as digital by default, allowing for electronic communication unless a recipient opts out.
Proponents may argue that the regulations modernize tax administration by allowing HMRC to use electronic communications as the standard method for designated matters.
The document specifies that digital contact details are necessary for the use of HMRC online services, which ensures the agency maintains up-to-date information for communicating with taxpayers.
The explanatory note mentions that a Tax Information and Impact Note was published in 2025 to summarize the impacts of these administrative changes.

Arguments Against

Legal commentators might note that the regulations grant broad powers to the Commissioners to specify taxation matters as 'default digital' via directions, which may limit parliamentary oversight of future expansions.
Civil liberties organizations or taxpayer advocates might express concern regarding individuals who lack reliable internet access or digital literacy, as electronic communication becomes the primary method by default.
Implementation difficulties could arise for taxpayers who fail to provide updated digital contact details, as the regulations authorize HMRC to restrict access to online services as a penalty for non-compliance.
Ambiguity may exist regarding what constitutes a 'reasonable excuse' for failing to provide digital contact details, as this determination is left to the satisfaction of the Commissioners.

Part 1 Citation, commencement and interpretation

Citation and commencement

These Regulations may be cited as the Digital Communications and Contact Details Regulations 2026 and come into force on 3rd August 2026.

This section establishes the official title of the instrument and sets the date of August 3, 2026, for when the legal requirements become effective. It ensures that the regulations are appropriately identified in subsequent legal or administrative references.

Interpretation

In these Regulations-

'the 2003 Regulations' means the Income and Corporation Taxes (Electronic Communications) Regulations 2003;

'the Commissioners' has the same meaning as in section 261(6) of the Finance Act 2026;

'default digital matter' means a default digital matter within the meaning of regulation 3(1);

'direction' means specific or general direction;

'HMRC' has the same meaning as in section 261(6) of the Finance Act 2026.

Part 2 defines the key terminology used throughout the document to ensure consistent application of the law.

It clarifies that references to the Commissioners and HMRC are tied to the definitions found in the Finance Act 2026 and provides shorthand for the 2003 Regulations and 'default digital matters'.

Part 2 Communicating digitally by default

Default digital matters

-(1) The Commissioners may by direction specify that a taxation matter is a default digital matter.

(2) HMRC may use electronic communications in connection with a default digital matter unless the recipient-

(a) has notified HMRC of an election not to receive electronic communications in connection with that matter, and
(b) has not notified HMRC of the withdrawal of that election.

(3) The Commissioners may by direction make provision as to the form, content, timing and manner of notification of-

(a) an election under paragraph 2(a);
(b) a withdrawal under paragraph 2(b) of such an election.

(4) The Commissioners may by direction make provision, in connection with a relevant use of electronic communications by HMRC, as to the manner of proving for any purpose-

(a) whether such a use of electronic communications is to be taken to have resulted in the delivery of information;
(b) the time of such a delivery of information;
(c) the contents of the information so delivered.

(5) In paragraph (1), 'taxation matter' has the same meaning as in section 261(6) of the Finance Act 2026.

(6) In paragraph (4), a use of electronic communications by HMRC is 'relevant' if it is made-

(a) in pursuance of paragraph (2), and
(b) in connection with a default digital matter not falling within regulation 2(1)(a) of the 2003 Regulations (scope of these regulations).

This provision allows HMRC to transition specific tax-related activities to a digital-first communication model via administrative directions.

It grants taxpayers the right to opt out of electronic communications by notifying HMRC, while also giving the Commissioners authority to set the rules for how delivery and receipt of digital information are legally proven.

Amendment of the Income and Corporation Taxes (Electronic Communications) Regulations 2003

-(1) The 2003 Regulations are amended as follows.

(2) In regulation 3 (use of electronic communications), in paragraph (1), after 'regulation 2(1)', insert ', except for default digital matters within the meaning of regulation 3(1) of the Digital Communications and Contact Details Regulations 2026 (default digital matters),'.

This section modifies existing legislation from 2003 to ensure there are no legal conflicts between older electronic communication rules and these new regulations.

By inserting this exception, it prioritizes the 2026 rules for any matter designated as 'default digital'.

Part 3 Digital contact details

Requirement to provide digital contact details

-(1) A person who uses an online service provided by HMRC in connection with a default digital matter must-

(a) provide to HMRC such digital contact details as the Commissioners may by direction specify in relation to the online service and the matter, and
(b) if the person ceases to use digital contact details provided to HMRC in pursuance of paragraph (a)-
(i) inform HMRC of that fact, and
(ii) provide to HMRC alternative digital contact details as specified under paragraph (a).

(2) The person must provide any information mentioned in paragraph (1)-

(a) in such form and manner, and
(b) at such time, including on a recurring basis,

as the Commissioners may by direction specify in relation to the online service and the matter.

(3) The Commissioners may by direction provide that a person who fails to comply with an obligation-

(a) to provide any information mentioned in paragraph (1), or
(b) to do so in accordance with paragraph (2),

may not use the online service in connection with the matter and such other matters as the direction may specify until the person provides the information to HMRC and does so in accordance with paragraph (2)(a).

(4) A direction under paragraph (3) may provide that the consequence under that paragraph of a person's failure does not arise where the Commissioners are satisfied that the person had a reasonable excuse for the failure.

This section mandates that anyone using HMRC's online services for designated digital matters must provide and maintain valid digital contact information.

If a user fails to provide these details or keep them updated, HMRC is authorized to block their access to those online services, unless the user presents a reasonable excuse for the failure that is acceptable to the Commissioners.
