HMRC Account Freezing Orders: Guide to Challenge AFOs 2025

An Account Freezing Order (AFO) is a court order issued by a UK Magistrates’ Court that prevents the holder of a bank account from accessing or moving the funds within it. This measure is used by enforcement agencies, such as HMRC, the Serious Fraud Office (SFO), the National Crime Agency (NCA), or the police. When HMRC suspects that funds are linked to tax fraud, VAT evasion, undeclared income, or other unlawful tax-related activity, it can apply for an AFO to immediately block the account.

The primary goal is to preserve the money while HMRC investigates its origin and use, preventing it from being moved or spent before legal proceedings can take place. Even if you are not facing criminal charges, HMRC can keep your funds frozen for months, or even up to two years. If you or your business face an AFO, prompt legal advice is crucial. The sooner we intervene, the more options we have to protect your position and minimise disruption to your affairs.

Who Can Apply for an Account Freezing Order?

While various UK enforcement bodies can apply for an AFO, HMRC is one of the most frequent applicants, particularly in tax-related investigations. Under the Proceeds of Crime Act 2002 (POCA), only certain agencies have this power, including:

• HM Revenue & Customs (HMRC) – often in cases involving suspected tax fraud, undeclared income, VAT carousel fraud, or complex corporate tax evasion schemes. HMRC uses AFOs as part of its civil and criminal investigation toolkit, often in coordination with other agencies.
• The Police – generally in cases linked to serious organised crime, fraud, or other unlawful conduct. While their remit is wide, in tax-linked matters they may work alongside HMRC’s Fraud Investigation Service.
• The Serious Fraud Office (SFO) – typically in high-value corporate fraud and corruption cases, where funds may be tied to complex cross-border transactions.
• Accredited Financial Investigators (AFIs) – authorised officers within local authorities or other enforcement bodies trained to trace and preserve suspected criminal assets.

When HMRC makes an application, it is often supported by intelligence from banking data, international tax information-sharing agreements, or suspicious activity reports. Our experts regularly find HMRC using this power at the early stage of a tax investigation, often before the account holder is even aware they are under scrutiny. Acting fast at this point can prevent an investigation from escalating.

How Does HMRC Obtain an Account Freezing Order?

For HMRC to obtain an AFO, they must satisfy a Magistrates’ Court that there are reasonable grounds to suspect the funds are:

1. Recoverable property—money obtained through unlawful conduct; or
2. Intended for use in unlawful conduct—for example, to pay suppliers in a fraudulent scheme or move illicit profits offshore.

Each account covered by an AFO must hold more than £1,000. Importantly, the court can grant the order without notice to HMRC if telling them beforehand could prejudice their investigation or future forfeiture proceedings.

Once granted, the AFO takes immediate effect, blocking withdrawals and transfers. The account holder can only make transactions if the court specifically allows them, usually by way of a variation order. Our experience shows that courts are often persuaded to permit living expenses, essential business costs, or legal fees, provided the application is well-prepared and fully documented.

What Level of Proof is Needed for an AFO?

The evidential threshold for an AFO is significantly lower than in a criminal prosecution. HMRC does not need to prove beyond reasonable doubt that a crime has occurred, nor does it need to show that you are personally under investigation. The focus is on the money itself, if the court is persuaded there are reasonable grounds to suspect it is tainted or intended for unlawful use, the order will likely be granted.

This low bar means many perfectly legitimate account holders can find their funds frozen by HMRC pursuing an AFO while investigations drag on. If this happens to you, specialist legal representation is essential to challenge the basis of the order, seek a variation, or prepare for any forfeiture proceedings. Our experts have successfully dismantled applications by exposing flaws in the evidence and showing the lawful source of funds.

What Happens When HMRC Freezes Your Account?

An AFO can cause immediate and severe disruption. You will:

• Lose access to your funds: Without court approval, you cannot make withdrawals, payments, or transfers. This can halt business operations, delay salaries, or prevent payment of suppliers. For individuals, it can leave you unable to cover living costs.
• Face operational and reputational damage: For companies, news of an account freeze can undermine confidence with clients, partners, and investors. Personal and corporate credit facilities can also be affected.
• Risk contempt of court: Attempting to bypass the freeze or failing to comply with the order’s terms can lead to serious legal consequences.

Courts do have the power to make exceptions, known as exclusions, to allow payment of essential living expenses, critical business costs, or legal fees. These applications must be carefully prepared and justified with the help of our expert solicitors.

How Do You Challenge an HMRC Account Freezing Order?

You have the right to challenge or vary an HMRC AFO. You can apply to the Magistrates’ Court to:

• Discharge the order – removing it entirely if it was wrongly granted.
• Vary the order – adjusting its terms to allow for necessary expenses or to exclude certain funds.

Challenges may succeed where:

• The evidence linking the funds to criminal conduct is weak or speculative.
• The order is overly broad and threatens the viability of a business.
• Legitimate sources of funds have been overlooked or ignored by the applicant agency.

A variation application will usually require full disclosure of your financial circumstances. In some cases, negotiating directly with HMRC can lead to a quicker resolution without the need for a contested hearing. Having solicitors experienced in AFO disputes is critical; poorly prepared challenges can harden the HMRC’s position and make resolution harder.

How Can You Prevent Permanent Loss of Your Funds?

An AFO is often a precursor to a Forfeiture Order, which permanently transfers the frozen funds to the state. HMRC must give at least 30 days’ notice before seeking forfeiture. If you fail to object in time, the money will be lost.

If you do object, HMRC will have to persuade the court, on the balance of probabilities, that the funds are recoverable property or intended for unlawful use. This is still a relatively low standard of proof, making early, robust legal defence essential.

A successful challenge can result in:

• Full recovery of your funds – with the freeze lifted entirely.
• Partial release – allowing access to funds for business or personal needs.
• Compensation – in rare cases, where the freeze caused provable loss due to agency error or overreach.

At LEXLAW, we have overturned forfeiture applications by exposing flawed financial tracing, proving lawful sources of funds, and undermining the credibility of the HMRC’s case. In tax-linked disputes, this often involves expert forensic accounting to demonstrate legitimate income and transaction history.

How Long Can an Account Freezing Order Last?

An HMRC AFO can last for up to two years, depending on the court’s order. During this period, HMRC will continue its investigation, often working to build a forfeiture case. At the end of the term, HMRC must either apply for forfeiture or ask the court to discharge the order.

For individuals and businesses, a prolonged freeze can be devastating. This is why our expert solicitors act quickly to shorten the lifespan of an AFO where possible, either through negotiated settlement or by persuading the court that continued freezing is unjustified.

Are Funds Automatically Forfeited at the End of an AFO?

No. There are two routes to forfeiture:

1. Notice procedure: HMRC serves at least 30 days’ notice of its intention to forfeit the funds. If no objection is filed, the money is forfeited without a hearing. This is why failing to act quickly can be fatal to your case.
2. Direct court application: HMRC applies to the Magistrates’ Court for a Forfeiture Order. The court decides based on the civil standard of proof, ‘balance of probabilities’. Even at this stage, a strong defence can succeed, but the preparation must be thorough.

Are There Any Exceptions to the Freeze?

Yes. While withdrawals are generally prohibited, the court can grant exceptions for:

• Reasonable living expenses – such as rent, utilities, and household costs.
• Legal expenses – to fund your defence in the AFO or related proceedings.
• Business costs – to allow a company to keep trading, pay staff, and meet contractual obligations.

Securing these exemptions requires persuasive evidence and a clear explanation of why the spending is necessary. At LEXLAW, we often prepare detailed financial schedules and affidavits to strengthen these applications, helping clients maintain normal operations while the freeze is in place
