Received a Schedule 36 Information Notice From HMRC?

A Schedule 36 information notice is a formal written demand, issued under Schedule 36 to the Finance Act 2008, requiring you to provide documents or information HMRC reasonably needs to check a tax position. It is a legal instrument, not a friendly reminder, and non-compliance carries statutory penalties.

HMRC can issue these notices to a taxpayer directly, or in limited circumstances to a third party who holds relevant records, such as a bank or accountant. The notice should specify the tax, the period, and precisely what is required. If it is vague or unreasonably broad, that can itself be grounds to query or appeal it.

Notices are used across Self Assessment, Corporation Tax, VAT and other compliance checks. They often appear once an HMRC officer decides correspondence alone is not producing sufficient answers, or where the officer wants to place the request on a formal statutory footing from the outset.

HMRC typically escalates to a formal notice when it believes voluntary requests have been slow, incomplete or ignored, or when the case involves risk indicators that justify a firmer approach from the start. It does not automatically mean HMRC suspects fraud.

Common triggers include unexplained discrepancies between declared income and known assets or lifestyle, third-party data such as property, platform or overseas information, inconsistent figures across returns, or a compliance check that has stalled because earlier informal requests went unanswered.

Sometimes a notice is issued simply because the officer's internal process requires a formal footing before certain records can be examined, particularly personal financial information. A formal notice is a procedural step, and its use should be assessed on the facts of your case rather than assumed to signal the worst.

HMRC can require documents or information reasonably needed to check your tax position, which can include personal bank statements where relevant, business records, contracts and correspondence. The test is relevance and reasonableness, not simply what HMRC would find convenient to see.

You can refuse to comply where a request is not reasonably required, is protected by legal professional privilege, or relates to matters outside the notice's stated scope. Refusing outright without challenging the notice formally is risky; the correct route is usually to ask HMRC to narrow the request or to appeal.

Where the notice was not approved by the tribunal, you generally have a right of appeal within 30 days against the requirement, or against specific items within it. Tribunal-approved notices carry more limited rights of challenge, so understanding which type you have received matters before deciding how to respond.

There is no fixed overall timescale. The stated response period is often around 30 days, but the wider compliance check the notice sits within can run for months, particularly if records are extensive or HMRC raises follow-up questions after reviewing your response.

Once HMRC has what it needs, the check may close with no further action, or move to proposing an adjustment to your tax position. A notice itself is a single step; it does not conclude the underlying enquiry, and further notices or requests can follow if gaps remain.

Keeping a clear paper trail of what was requested and provided helps bring matters to a close more quickly, since it reduces the scope for HMRC to say information was missing or ambiguous.

Failing to comply with a valid notice by the deadline can trigger an initial fixed penalty, followed by further daily penalties if the failure continues, and potentially higher penalties for persistent or serious non-compliance. These are separate from any penalty arising from an underlying tax inaccuracy.

If the notice also uncovers an error in your tax affairs, any related penalty depends on behaviour: broadly, careless errors attract a lower penalty range than deliberate ones, and unprompted disclosure before HMRC intervenes attracts more reduction than a prompted admission made only once HMRC has already raised the point.

Cooperating fully and promptly with a valid notice, and correcting any error you identify while responding, are the practical ways to keep penalty exposure at the lower end of what the legislation allows, rather than assuming a fixed percentage applies automatically.

The most damaging mistake is doing nothing and letting the deadline pass, since penalties accrue automatically once a valid notice is unmet, regardless of whether you intended to respond eventually.

Other common errors include sending an unindexed pile of documents that does not map to the request, giving partial answers without explaining the gaps, altering or recreating records rather than explaining what genuinely does not exist, and assuming an informal phone call satisfies a written statutory notice.

Taxpayers also sometimes appeal reflexively without checking whether the notice is genuinely open to appeal, missing the true deadline while an unfounded appeal is considered. Establishing the correct legal position before acting avoids these avoidable errors.

Consider a Croydon-based IT contractor who receives a Schedule 36 notice asking for personal bank statements covering two tax years, alongside invoices for the same period. HMRC's letter states the request follows a discrepancy between declared turnover and payments recorded by an agency.

The contractor's first step is checking the notice is validly issued and noting both the response and appeal deadlines. Reviewing the bank statements shows most transactions are personal and unrelated to the contracting income, so the response includes a covering schedule identifying which entries relate to business receipts and which do not, rather than handing over unexplained statements.

Where invoices for one quarter are missing because a client used a different payment platform, the response explains this gap and supplies the corresponding platform statement instead. This approach — engaging with the scope, being transparent about gaps and meeting the deadline — is generally more effective than blanket compliance or blanket refusal.
