Do I need a fiscal representative for UK VAT?
Usually not. The UK doesn’t require overseas businesses to appoint a tax representative (sometimes called a fiscal representative) to register. You only need one if HMRC directs you to, and HMRC cannot direct businesses based in countries with certain mutual assistance arrangements with the UK. HMRC can also ask for a security instead.
What is the difference between a VAT agent and a tax representative?
| Tax representative | Agent | |
|---|---|---|
| Liability for your VAT debts | Jointly and severally liable | Not liable |
| When required | Only if HMRC directs you | Never required; your choice |
| What they do | Keep your VAT account, file returns and pay VAT for you | Whatever you agree: often registration and returns |
| Who can act | UK-based and “fit and proper” in HMRC’s view | Anyone HMRC is willing to deal with |
| Paperwork | Form VAT1TR, signed by both, within 30 days | A letter authorising the agent |
| Typical cost | Higher, because they carry your liability | Lower |
When can HMRC make me appoint a tax representative?
HMRC can direct some non-established businesses to appoint a UK tax representative. In practice this is more likely where your country has no mutual assistance arrangement with the UK, or where HMRC has concerns about compliance. Overseas marketplace sellers who don’t meet their VAT obligations can also be directed to appoint one.
What makes a tax representative “fit and proper”?
HMRC may refuse a representative who, for example:
- has been disqualified as a director, or has relevant criminal convictions
- has had penalties for deliberate wrongdoing, or a fraudulent trading history
- has a connection with the business they want to represent
- holds no assets or insurance, or hasn’t met their own tax obligations
- is bankrupt or in an individual voluntary arrangement
Can I do it all myself?
Yes, if HMRC hasn’t directed you to appoint a representative. You must then register on time, keep records, file returns and pay the right VAT yourself.
Common scenarios
“What’s the difference between a VAT agent and a fiscal representative in the UK?”
Liability. A fiscal (tax) representative is jointly and severally liable for your UK VAT debts, so HMRC can pursue them if you don’t pay. An agent just acts for you and carries no liability. Most overseas businesses only need an agent.
“HMRC has written directing us to appoint a representative.”
The direction may give a deadline. You need a UK-based, fit and proper representative, and you both sign form VAT1TR. Representatives carry real risk, so expect identity checks and questions about your business first.
Need a UK VAT agent?
We act as VAT agent for overseas businesses: registration, HMRC correspondence and MTD VAT returns. We don’t act as tax representative, but we can tell you whether you need one.
Frequently asked questions
Can I have more than one tax representative?
No. You can only appoint one person at a time, although a representative can act for several businesses.
Can I limit my tax representative’s liability?
No. HMRC will not accept any arrangement that tries to limit a representative’s joint and several liability.
Can HMRC refuse to deal with my agent?
Yes. HMRC reserves the right not to deal with a particular agent and may, if necessary, still insist on a tax representative.
Does my tax representative need to be VAT-registered?
No. A representative doesn’t need to be VAT-registered to act, although they may need to register for their own business.
