Fiscal representative in the UK: when HMRC requires a VAT representative

Many overseas businesses are told they need a fiscal representative in the UK before they can register for VAT. HMRC guidance says otherwise: a VAT representative is optional unless HMRC directs you to appoint one. Here is how fiscal representation in the UK works, what it costs you in liability terms and how it differs from customs representation.

This guide is also available in Polish.

The short answer

A business based outside the UK does not need a fiscal representative in the UK simply because it registers for UK VAT. HMRC's VAT Notice 700/1 says a non-established taxable person (NETP) may appoint a tax representative, may instead use an agent, or may deal with HMRC directly. A representative becomes compulsory only if HMRC directs you to appoint one, and HMRC cannot give that direction to NETPs based in countries where certain mutual assistance arrangements exist.

"Fiscal representative" is the everyday commercial term. HMRC's guidance uses "tax representative" or "VAT representative" for the same role, so you will see all three when researching fiscal representation in the UK.

Who this applies to

These rules concern NETPs: businesses with no UK establishment. For an NETP the usual VAT registration threshold does not apply, so registration is required as soon as you make taxable supplies in the UK or expect to within the next 30 days. Whether and when you need to register is covered in our guide to UK VAT registration for EU businesses. This guide picks up from there and focuses on the question that follows: who will stand between you and HMRC once you are registered.

Your three options under VAT Notice 700/1

Option	Who accounts for the VAT	Liability for your VAT debts
Tax (fiscal) representative	The representative keeps your VAT records and accounts and accounts for UK VAT on your behalf	Jointly and severally liable with you
Agent	Works under your contract with them, for example filing returns and corresponding with HMRC	HMRC cannot hold the agent responsible for your VAT debts
No representative or agent	You deal with HMRC yourself	You alone

If you appoint neither, Notice 700/1 lists what you must then handle yourself: registering on time, keeping records and producing them for inspection, keeping track of VAT paid and charged, and paying the correct tax on time.

What a fiscal representative in the UK actually takes on

The defining feature of a fiscal representative in the UK is liability. Under Notice 700/1 a tax representative is jointly and severally liable for any VAT debts you incur. In practice that means the representative shares responsibility for VAT you owe, so the agreement between you, and how VAT payments and information flow, matters to both sides.

Some further points from HMRC's guidance:

You can have only one tax representative at a time, although one representative can act for several businesses.
The representative must be given enough information to keep a VAT account, make returns and pay VAT for you.
Where HMRC directs an appointment, the representative must be based in the UK and be "fit and proper", which the notice describes as meeting a particular level of suitability, compliance and integrity.
If HMRC concludes a representative may not be fit and proper, it can cancel their registration as your representative; if you were directed to have one, you must then appoint a replacement.

When HMRC can require one

Notice 700/1 gives HMRC two tools for NETPs that it considers a risk: it can direct you to appoint a VAT representative, or it can ask you to pay a security. The same notice says HMRC cannot direct NETPs who are based in countries where certain mutual assistance arrangements exist. The notice does not list those countries, so do not assume either way; if HMRC writes to you about a representative or security, ask it to set out the basis.

Even if you have chosen an agent rather than a representative, the notice warns that HMRC may still insist on a tax representative in some circumstances "if we think it's necessary". Claims that every overseas business must appoint a fiscal representative before it can register do not match this guidance; neither do claims that HMRC can never require one.

A direction or a security request from HMRC is a formal step. Read it carefully, note any deadline it gives and take advice before you respond.

Using an agent instead

If HMRC has not directed you to appoint a representative, Notice 700/1 allows you to appoint an agent to deal with your UK VAT affairs. HMRC needs your written authority before it will deal with the agent, and the notice includes a model letter in which the business appoints a named agent to deal with its VAT obligations and submit returns. Because an agent carries no liability for your VAT debts, this is a lighter arrangement for both sides, but you remain fully responsible for getting the VAT right.

How the appointment is notified

When you register for VAT online as an NETP you are asked for details of your tax representative if you have one. HMRC's form VAT1TR is used to appoint a tax representative when a non-established taxable person registers for UK VAT; GOV.UK says it can be completed or uploaded during online registration, an option available since 21 May 2024. Even when an agent handles things for you, the notice reminds you that the appropriate registration form must still be completed.

Fiscal representation is not customs representation

A common mix-up is to assume that the firm acting as your VAT representative also covers customs, or the reverse. They are separate regimes with separate liability rules. For customs, HMRC guidance distinguishes:

Direct representation: the agent declares in your name and you are solely liable for the declaration and any duty or import VAT due.
Indirect representation: the agent declares in its own name on your behalf and is jointly and severally liable for any customs duty or import VAT.

HMRC also says that if you are not established in the UK and import goods into Great Britain, you can only ask someone to act for you indirectly. So a non-UK business importing its own stock may well end up with an indirect customs representative for imports and, separately, an agent or a fiscal representative for its VAT returns. Our guide to direct and indirect customs representation explains the customs side in more detail.

Practical checklist

Confirm you are an NETP and when your first UK taxable supply will be.
Decide between a tax representative, an agent or handling HMRC yourself.
If you choose a representative, agree in writing how VAT payments and information will flow, given their joint and several liability.
If you choose an agent, give HMRC written authority.
Include the representative's details at registration, using form VAT1TR where needed.
Arrange customs representation for imports separately.
Keep any HMRC letter about a direction or security and respond within its deadline.
