An HMRC Schedule 36 information notice is a formal statutory demand for documents and information. It is not a request, refusal or non-compliance triggers automatic penalties and, ultimately, criminal investigation risk. But Schedule 36 is not unlimited: HMRC can only demand what is “reasonably required” to check your tax position and several important categories of material are entirely protected. This guide explains everything you need to know.

What is Schedule 36 Finance Act 2008?
Schedule 36 of the Finance Act 2008 is HMRC’s primary statutory power to obtain information and documents from taxpayers and third parties. Before Schedule 36 came into force, HMRC’s information-gathering powers were scattered across numerous different statutes, one regime for income tax, another for VAT, another for corporation tax, with inconsistent rules and thresholds. Schedule 36 consolidated and modernised all of these into a single, consistent framework.
The Schedule gives HMRC officers the power to issue formal notices requiring the production of “information” and “documents” that are “reasonably required” for the purpose of checking a taxpayer’s tax position. These terms are each defined and constrained by the legislation, creating a framework that is powerful but not unlimited.
Schedule 36 notices can be issued in relation to any tax administered by HMRC, income tax, capital gains tax, corporation tax, VAT, PAYE, inheritance tax and others. They can be issued during a formal enquiry or independently of one, and they can target the taxpayer directly or a third party who holds relevant information.
The four types of Schedule 36 notice
1. Taxpayer Notice (paragraph 1)
A taxpayer notice is issued directly to the taxpayer whose tax position is being checked. It is the most common type of Schedule 36 notice in practice. Critically, a taxpayer notice does not require prior approval from the First-Tier Tribunal (FTT), HMRC can issue it unilaterally. The one exception is where HMRC seeks information or documents relating to a period that is already “closed” (i.e. the self-assessment enquiry window has expired and no enquiry is open): in that case, paragraph 1(3) requires FTT approval before the notice can be issued.
2. Third-Party Notice (paragraph 2)
A third-party notice is issued to a person other than the taxpayer, for example, a bank, an accountant, a solicitor, a business partner or an employer, requiring them to produce information or documents relevant to checking the taxpayer’s tax position. Because the notice is served on someone other than the taxpayer, paragraph 3 imposes an additional safeguard: a third-party notice requires either the taxpayer’s written agreement or prior approval of the FTT before it can be issued.
3. Third-Party Notice to Financial Institutions (paragraph 4)
Where HMRC wishes to obtain information from a “financial institution” (banks, building societies, investment firms and similar entities), paragraph 4 imposes an even higher threshold: FTT approval is always required, regardless of whether the taxpayer consents. This reflects Parliament’s view that financial institution data, covering account histories, transaction records and balance information, is especially sensitive. The FTT must be satisfied that HMRC has reasonable grounds for issuing the notice before approving it.
4. Inspection Notice (paragraph 10)
An inspection notice authorises an HMRC officer to enter the taxpayer’s business premises, inspect documents held there, inspect assets and observe business activities. This is the “visit” power. Unlike the first three types, it applies to physical presence on premises rather than document production. Notice of inspection must normally be given in advance (typically at least 7 days under paragraph 11). The FTT can approve an unannounced inspection where prior warning would “prejudice” the purpose of the inspection (paragraph 13).
What HMRC can demand
Schedule 36 empowers HMRC to require the production of “information” and “documents” that are “reasonably required” for the purpose of checking the taxpayer’s tax position. Each element of this formula is important:
- “Information” is broadly defined to include data held in any form, electronic records, emails, spreadsheets and data extracts, as well as paper documents.
- “Documents” means anything in which information is recorded, including accounts, correspondence, contracts, invoices and bank statements.
- “Reasonably required” is the critical limiting phrase. It imports a proportionality requirement: the documents or information must be genuinely needed to check the tax position, and the burden of complying must not be grossly disproportionate to the purpose. This is not a low bar for the taxpayer to clear, but it is not illusory either.
In practice, HMRC commonly requests: bank statements (personal and business), accounting records and working papers, records of property transactions, dividend vouchers, loan agreements, correspondence with overseas entities, payroll records and VAT records. Where the notice is specific and proportionate, these will generally be within scope.
What HMRC cannot demand
Schedule 36 contains several statutory protections. Documents and information falling within these categories cannot lawfully be demanded, even under a valid notice:
(a) Legal Professional Privilege, paragraph 23
Documents that attract legal professional privilege (LPP) are entirely protected. LPP covers: advice given by a solicitor or barrister to a client in a legal capacity; and communications made for the dominant purpose of litigation that is reasonably anticipated. Tax counsel opinions, solicitors’ letters of advice and legally privileged correspondence cannot be compelled under Schedule 36. Note that “tax adviser privilege” under paragraph 25A is narrower, it does not cover preparatory or compliance work, only advice with legal character.
(b) Personal Records, paragraph 24
Documents that are “personal records” within the meaning of PACE 1984, broadly, medical, psychiatric, social work and counselling records relating to a living individual, are protected.
(c) Journalistic Material, paragraph 25
Journalistic material held in confidence for journalistic purposes cannot be demanded under Schedule 36.
(d) Information Not in the Taxpayer’s Possession or Power, paragraph 18
HMRC can only require documents and information that are in the taxpayer’s “possession or power.” If documents have been genuinely lost, destroyed or are held by a party beyond the taxpayer’s control (and the taxpayer has no legal right to require their production), they are outside the scope of the notice.
(e) Statutory Accounts, paragraph 21
Where a company is exempt from statutory audit, HMRC cannot use a Schedule 36 notice to demand statutory accounts that the company is not legally required to prepare. This is a narrow but occasionally relevant protection for small companies.
The taxpayer notice process
When HMRC issues a taxpayer notice, the process typically runs as follows:
- Notice issued. HMRC sends a formal letter identifying the documents or information required, usually with a list or schedule attached.
- Compliance period. The notice will specify a deadline, typically 30 days from the date of the notice, though HMRC sometimes specifies longer or shorter periods depending on the volume of material requested.
- Taxpayer reviews the notice. Each item should be assessed for scope, privilege and whether it is within the taxpayer’s possession or power.
- Clarification or negotiation. It is legitimate to seek clarification from HMRC on the purpose of any item in the notice or to propose a narrower set of documents that addresses HMRC’s underlying purpose.
- Production or appeal. If the notice (or part of it) is unduly onerous or lacks a valid purpose, an appeal to the FTT is available within 30 days.
Approval requirements
The approval requirements under Schedule 36 vary by type of notice:
- Taxpayer notices (para 1): No tribunal approval required in most cases. Exception: if the enquiry window for the relevant period is closed, para 1(3) requires FTT approval before the notice can be issued.
- Third-party notices (para 3): Require either the taxpayer’s written agreement or FTT prior approval. The FTT application is made without notice to the taxpayer; the FTT applies a relatively low threshold, needing only to be satisfied that HMRC has reasonable grounds.
- Financial institution notices (para 4): FTT approval always required, no taxpayer consent alternative.
- Inspection notices (para 11–13): Usually require at least 7 days’ advance notice to the taxpayer. Unannounced inspections require FTT approval.
Your appeal rights
Paragraph 29 of Schedule 36 gives a taxpayer the right to appeal a taxpayer notice to the FTT on either of two grounds:
- The notice, or any requirement within it, is “unduly onerous” in the circumstances; or
- HMRC does not have the purpose of “checking the taxpayer’s tax position” , i.e. the notice is a fishing expedition or has an improper purpose.
The appeal must be lodged with the FTT within 30 days of the notice being issued. The FTT can suspend the compliance deadline pending determination of the appeal, which is an important interim protection.
There are important limits to this appeal right:
- Taxpayers have no right of appeal against a third-party notice , only the recipient of the third-party notice (e.g. the bank or accountant) has standing to challenge it. In practice, third-party recipients rarely appeal.
- Where the FTT has already given advance approval to a notice, that approval cannot itself be appealed via paragraph 29.
- Judicial review of HMRC’s decision to issue a third-party notice remains theoretically available but is a high-threshold and expensive remedy.
Interaction with enquiries and COP9
A common misconception is that Schedule 36 notices can only be issued once a formal enquiry has been opened. This is incorrect. HMRC can issue a Schedule 36 notice at any time, including before opening a formal self-assessment enquiry, provided it has a genuine checking purpose. This means HMRC sometimes uses Schedule 36 notices to gather preliminary information that then informs whether to open an enquiry or launch a COP9 investigation.
Where HMRC has opened a COP9 Code of Practice 9 investigation, it may issue Schedule 36 notices as part of that process. The interaction is important: if HMRC is using Schedule 36 for a criminal investigation purpose rather than a civil checking purpose, the notices may be challengeable on the ground of improper purpose. Specialists experienced in COP9 work will recognise this situation. See also our guide to income tax investigations.
Practical response strategy
Receiving a Schedule 36 notice calls for a methodical response, not a panic. The following approach is what specialist practitioners follow:
- Acknowledge receipt. Do not ignore the notice. The compliance clock starts from the date of the notice regardless of when you read it.
- Assess each item for privilege. Go through every document or category of document requested and identify anything that may attract LPP or another protection. Set those aside immediately.
- Seek clarification of HMRC’s purpose. Write to HMRC asking it to confirm, in relation to any items you are uncertain about, why those items are “reasonably required” to check your tax position. HMRC’s response (or refusal to respond) may itself be relevant to an appeal.
- Negotiate scope reduction. In many cases, HMRC will accept a narrower set of documents that genuinely addresses its concern. This saves time and avoids producing material that could give HMRC unintended avenues of investigation.
- Consider whether to appeal. If the notice is unduly burdensome or has an improper purpose, appeal to the FTT within 30 days. Even where the appeal is unlikely to succeed in full, it buys time and forces HMRC to articulate its purpose.
- Produce compliant documents. Only then produce what has been agreed or determined to be within scope, in a clearly organised form.
Frequently asked questions
Can HMRC search my premises without a warrant under Schedule 36?
No. Schedule 36 paragraph 10 gives HMRC a right to inspect business premises, but only with proper advance notice (usually at least 7 days) or FTT approval for an unannounced inspection. HMRC cannot use Schedule 36 to force entry. Separate powers under PACE 1984 apply to criminal investigations and require a court warrant.
Does Schedule 36 override legal professional privilege?
No. Paragraph 23 explicitly preserves legal professional privilege. Documents that attract LPP, including solicitors’ advice letters, tax counsel opinions and privileged correspondence, cannot be compelled under Schedule 36. If you believe documents are privileged, assert that privilege in writing before the compliance deadline and take specialist advice.
What happens if I ignore a Schedule 36 notice?
An automatic £300 fixed penalty arises under paragraph 39 for failure to comply without reasonable excuse. If non-compliance continues, HMRC can apply to the FTT for daily penalties of up to £60 per day. Persistent non-compliance may lead HMRC to raise discovery assessments on estimated figures and potentially refer the case for criminal investigation.
Can HMRC demand documents that pre-date the enquiry period?
Yes, where those documents are reasonably required to check the taxpayer’s current tax position, for example, to establish the historic cost of assets or to trace the origins of funds. However, the request must still satisfy the proportionality test. Documents relating to years that are fully and formally closed may be beyond HMRC’s legitimate reach.
