Clear Junction tax self-certification update: client FAQs

Clear Junction is currently asking relevant clients to review and, where necessary, update the tax information we hold about their organisation.

The exercise supports our obligations under international tax-transparency frameworks, including the Common Reporting Standard (CRS), as updated requirements apply to the 2026 reporting year.

If your organisation has been contacted by Clear Junction, please complete or update your Tax Residency & Regulatory Self-Certification as soon as possible.

Below we answer the main questions about the exercise and what you may need to provide.

About the exercise

Why has Clear Junction contacted my organisation?

Clear Junction may already hold tax and corporate information about your organisation. We may still need you to review, confirm or update that information.

This can arise where information previously provided is incomplete, your organisation’s circumstances have changed, existing records need clarification, or updated reporting requirements require additional information.

For the 2026 calendar year onwards, UK Reporting Financial Institutions are also required to report additional CRS information, including whether a valid self-certification is held for relevant Reportable Account Holders and Controlling Persons.

When should I complete my self-certification?

Please complete or update your Tax Residency & Regulatory Self-Certification as soon as possible. Prompt submission allows our teams to review the information and follow up where clarification is required.

What you may need to provide

What information might I need to provide?

The information required will depend on your organisation and its circumstances. You may be asked to provide or confirm:

• your organisation’s jurisdiction or jurisdictions of tax residence;
• the relevant Tax Identification Number, or TIN, for each jurisdiction where one is required;
• your organisation’s CRS entity classification;
• information about relevant Controlling Persons, where applicable; and
• confirmation from somebody authorised to complete the declaration on behalf of your organisation.

For entity self-certifications, HMRC guidance requires information including the entity’s name, address, jurisdiction or jurisdictions of tax residence and relevant TINs. The declaration must also be signed or otherwise positively affirmed by somebody authorised to act for the entity.

Why am I being asked to confirm information Clear Junction may already hold?

A self-certification is more than a collection of individual data fields. The organisation needs to confirm that the information being provided accurately reflects its current circumstances.

Existing information can also become unreliable following a relevant change in circumstances. For example, a change to tax residence, ownership, corporate structure or other information may mean that an earlier self-certification needs to be reviewed.

My organisation is tax resident in more than one country. What should I provide?

Under updated international rules (CRS 2.0) effective from 1 January 2026, entities completing a UK CRS self-certification may no longer rely on tax-treaty tie-breaker rules to select a single jurisdiction for reporting purposes.

All jurisdictions where your organisation is tax resident must be declared, along with the relevant Tax Identification Number (TIN) for each jurisdiction.

Please note that this is a statutory reporting requirement under HMRC guidance. Questions about the wider application of tax treaties to your organisation should be considered separately with the relevant tax authority or an appropriate professional adviser.

Who can complete the self-certification for my organisation?

The declaration should be completed or positively affirmed by somebody with authority to act on behalf of the organisation.

HMRC guidance gives examples including an officer or director of a company, a partner of a partnership, a trustee of a trust or another person appropriately authorised to act for the entity.

How Clear Junction can help

Can Clear Junction tell me what my company’s tax residence or CRS classification should be?

Clear Junction can explain the information we are requesting and support clients with the practical aspects of completing our process.

Tax residence, the appropriate TIN and CRS or FATCA classification depend on the circumstances of the individual organisation and the rules that apply in the relevant jurisdictions.

Where you are uncertain about the declaration your organisation should make, please refer to the relevant tax authority’s guidance or seek appropriate independent professional advice.

Can Clear Junction complete the information for me?

Some information may already exist within our records and may be available as part of the process.

Your organisation will still need to review and positively affirm the information required for its self-certification. HMRC guidance also specifically excludes an account holder’s jurisdiction or jurisdictions of tax residence from information that a Reporting Financial Institution can pre-populate on a CRS self-certification.

What happens if I have difficulty completing the process?

Your Clear Junction contact can help with practical questions about the process, including access, the information fields being requested and any follow-up information Clear Junction requires.

Questions concerning your organisation’s tax residence, appropriate TIN or classification should be checked against the relevant tax authority’s guidance or discussed with an appropriate professional adviser.

After you submit

What happens after I submit the information?

Clear Junction will review the information provided as part of the client-information exercise.

Where information is incomplete, inconsistent with other information held, or requires clarification, our team may contact you for further information or an updated declaration.

A Reporting Financial Institution must consider whether a self-certification is reasonable in light of other customer information it holds, and a certification can become unreliable following a relevant change in circumstances.

What happens if my organisation does not provide the updated self-certification?

Clear Junction is required to maintain valid and up-to-date tax self-certifications for relevant account holders. If we do not receive a completed declaration, Clear Junction may be required to determine your tax status using existing information held in its records, which may result in your account being reported to HMRC. In certain circumstances, failure to provide mandatory regulatory documentation may also result in temporary restrictions being placed on your account.
