Account Freezing Orders: HMRC and the Criminal Finances Act 2017

An Account Freezing Order (AFO) can lock every pound in your business and personal bank accounts within hours, without a criminal charge, without advance notice and without your involvement in the court hearing. If HMRC has frozen your account, you need urgent specialist advice. This guide explains exactly how AFOs work, your rights and how to challenge them.

What is an Account Freezing Order?

An Account Freezing Order is a civil court order that prevents all withdrawals, transfers and payments from a specified bank or building society account. AFOs were introduced by Schedule 1 of the Criminal Finances Act 2017 and are now contained in ss303Z1–303Z19 of the Proceeds of Crime Act 2002.

The key features that distinguish AFOs from other POCA asset-freezing tools are:

• They are made in the magistrates’ court , a far lower threshold procedurally than the Crown Court
• They can be obtained without prior notice to the account holder (ex parte)
• No criminal charge or investigation need be under way, the order is entirely civil
• The standard is reasonable grounds to suspect , significantly lower than a criminal standard
• They operate against the account, not against the individual personally (unlike a restraint order)

AFOs represent a significant shift in asset-freezing law. Before their introduction, HMRC and other agencies had to go to the Crown Court for a restraint order, which required criminal proceedings to be either underway or about to begin. AFOs removed that requirement entirely, giving HMRC a rapid, low-threshold tool to immobilise funds while an investigation develops.

Who can apply for an AFO?

Section 303Z1(1) POCA defines an “enforcement officer” who may apply for an AFO as:

• A constable (police officer)
• An officer of HMRC
• An immigration officer
• A National Crime Agency officer
• A Financial Conduct Authority officer
• Any other person specified in regulations

HMRC officers are therefore fully empowered to apply for AFOs independently, without involving the NCA or the police. In practice, HMRC uses AFOs extensively in tax fraud investigations, VAT fraud cases and cases where it believes funds are about to be dissipated.

The “reasonable grounds to suspect” threshold

The threshold for obtaining an AFO is deliberately low. The magistrates’ court must be satisfied that there are reasonable grounds to suspect that the money in the account is either:

• Recoverable property (property obtained through unlawful conduct under Part 5 POCA 2002); or
• Property intended to be used in unlawful conduct

The magistrates do not determine whether the money actually is proceeds of crime, merely that there are reasonable grounds for suspicion. This is the same threshold as a police officer has to make an arrest. The fact that a taxpayer is under investigation, has received unexplained funds or has been identified via intelligence sources may be sufficient to meet this threshold.

Because the application is made ex parte (without the respondent being present or notified), the magistrates hear only HMRC’s evidence. There is no automatic right to make representations before the order is granted. The respondent’s challenge comes afterwards.

The ex parte application process

The AFO application process works as follows:

1. HMRC prepares a written application and supporting evidence, setting out the grounds for suspicion
2. The application is presented to a magistrates’ court (usually the local court or one with a designated financial crime magistrate)
3. The magistrate considers the application without notice to the respondent
4. If the order is granted, HMRC serves it on the relevant bank or building society
5. The bank freezes the account immediately upon receipt of the order
6. The respondent (account holder) is served with a copy of the order

In practice, the sequence from application to frozen account can be completed in a single day. The account holder frequently finds out only when a card payment is declined or when the AFO notification arrives, sometimes after the fact.

Duration: up to two years, extendable

An AFO can initially freeze an account for up to two years from the date it is made (s303Z3 POCA). HMRC can apply to extend the two-year period before it expires if it needs additional time to investigate or to prepare a forfeiture application. Extensions have been granted by courts where HMRC has demonstrated ongoing and active investigation.

Within the freezing period, HMRC must decide whether to bring an Account Forfeiture Order (AFOrO) application. If it does not do so before the AFO expires, the funds must be released.

Account Forfeiture Orders: the follow-on step

If HMRC believes the frozen funds are recoverable property, it will apply for an Account Forfeiture Order under s303Z14 POCA. This is the order that permanently transfers the funds to the state, it is the AFO equivalent of a confiscation order.

The AFOrO application is heard by the magistrates’ court, and the standard of proof is the civil standard (balance of probabilities): the court must be satisfied that the money in the account is recoverable property. The respondent has the right to appear, give evidence and adduce documents demonstrating the legitimate origin of the funds.

Many AFOrO applications are resolved by consent: the respondent agrees to forfeit a portion of the funds that cannot be explained, while the balance (which can be demonstrated to be legitimate) is released. This requires detailed forensic analysis of the account history and supporting documentation.

The respondent’s rights: variation and discharge

Section 303Z4 POCA gives the respondent (or any other person affected by the AFO) the right to apply to the magistrates’ court for the order to be varied or discharged. An application for discharge argues that the AFO should not have been made at all. An application for variation seeks to modify the order, for example, to release specific funds for particular purposes.

The grounds for discharge include:

• No reasonable grounds: HMRC’s intelligence was wrong, incomplete or the inference of suspicion was not reasonably available on the facts
• Legitimate funds: the funds in the account have a demonstrably lawful provenance (salary, inheritance, business income, property sale proceeds)
• Proportionality: the order is disproportionate to any suspected unlawful conduct, particularly where legitimate and potentially suspect funds are mixed in the same account
• Procedural irregularity: the AFO was not properly obtained or served

An application for variation to release funds for living expenses and legal costs is particularly important. A frozen account can leave an individual or a business unable to pay rent, wages or ordinary bills within days. Courts recognise this hardship and can release specified funds for these purposes, but the application must be properly framed and supported with evidence of need.

Substantive grounds of challenge in detail

No reasonable grounds for suspicion

This is the most direct ground of challenge. It requires demonstrating that, on the facts available to HMRC at the time of the application, it was not reasonable for HMRC to suspect the funds were recoverable property. This is a higher bar than it appears: the courts have held that “reasonable grounds” can be established by intelligence that would not itself be admissible as evidence. However, if the intelligence is demonstrably wrong (for example, HMRC wrongly identified the account holder or miscounted transactions), this ground is available.

Legitimate business funds

Where an account contains the proceeds of a legitimate business, even one that is also under tax investigation, demonstrating that the majority of funds are legitimately sourced can support both a discharge (if all funds are legitimate) and a variation (if some are). Business bank statements, invoices, PAYE records and VAT returns are all relevant evidence.

Proportionality

Even where some funds in an account may be suspect, freezing the entire account, including clearly legitimate income, may be disproportionate. HMRC has obligations under Article 1 Protocol 1 ECHR (protection of property rights) and courts will consider whether the order strikes a fair balance between the public interest in preventing money laundering and the respondent’s right to use their property.

AFOs vs restraint orders: the critical distinction

A restraint order under Part 2 POCA 2002 is made by the Crown Court and can freeze all of a defendant’s assets, property, vehicles, investments and bank accounts. It is linked to criminal proceedings (a prosecution must have been brought or be anticipated). The Crown Court has greater supervision over restraint orders and the threshold for obtaining them is higher.

An AFO is narrower in scope (bank and building society accounts only), requires a lower threshold and is available in the absence of any criminal proceedings. The magistrates’ court is a less formal forum but has significant power over the respondent’s financial position. AFOs are increasingly used as the first step in an enforcement strategy, with criminal proceedings (and a restraint order) following if HMRC develops sufficient evidence.

Where both a restraint order and an AFO exist, the Crown Court’s jurisdiction takes precedence and it can give directions to which the AFO must conform. In practice, the existence of a restraint order usually means the AFO becomes redundant and is discharged.

What HMRC actually freezes

HMRC can target any bank or building society account under ss303Z1–303Z19 POCA. In practice, HMRC will identify target accounts through:

• Tax returns and PAYE records identifying salary-receipt accounts
• Companies House data identifying business bank accounts
• Suspicious Activity Reports identifying accounts where unusual transactions have occurred
• Financial intelligence from the NCA or police
• Direct bank data obtained via financial investigation powers

Business current accounts, personal current accounts, savings accounts and cash ISAs can all be targeted. Joint accounts can be frozen even if only one holder is under investigation. Accounts held in the name of a connected company can be targeted separately.

Interaction with ongoing tax and COP9 proceedings

An AFO can be obtained by HMRC independently of any tax enquiry or COP9 investigation. In practice, the AFO power is most commonly used where:

• HMRC believes funds are at risk of dissipation before a tax liability can be assessed and collected
• A COP9 offer has been rejected or ignored, and HMRC is moving towards criminal referral
• HMRC has received intelligence suggesting funds are being moved offshore or between accounts

The existence of an AFO does not prevent HMRC from continuing a COP9 civil investigation. Both can run simultaneously. However, practically speaking, an AFO alongside a COP9 investigation signals that HMRC regards the risk of asset dissipation as real and imminent, which is itself an important indicator of how the investigation is developing.

Practical steps when you receive notification of an AFO

1. Do not panic, but act immediately. You have rights and they can be enforced. Time is critical.
2. Instruct a specialist immediately. A general solicitor or accountant may not have AFO experience. You need someone who has handled POCA proceedings specifically.
3. Identify all affected accounts. Check whether HMRC has targeted more than one account, AFOs are sometimes obtained against multiple accounts simultaneously.
4. Gather your financial records. Bank statements, payslips, invoices, business accounts, inheritance documents, property sale records, anything that demonstrates the legitimate origin of the frozen funds.
5. Apply for a variation urgently if needed for living expenses. Do not wait until you have a complete answer to the AFO, courts can grant emergency variations for essential expenditure.
6. Do not contact HMRC directly. Let your adviser manage all contact. Anything you say to HMRC can be used in the AFOrO proceedings.
7. Review whether you have any COP9 or tax enquiry correspondence. The AFO may be linked to a wider investigation you may not yet have been formally notified about.
