VAT5EXC Form Explained: How to Fill It Out for Your Small Business (UK Guide)

If HM Revenue and Customs has asked you to complete a VAT5EXC form, it usually means they want confirmation that your business does not need to be VAT registered.

What Is the VAT5EXC Form?

The VAT5EXC form is used to exclude or cancel a VAT registration where a business does not meet the legal requirement to be VAT registered.

HMRC typically requests this form when:

  • A VAT registration application raises questions
  • Reported turnover appears close to the VAT threshold
  • Your business activity is unclear
  • You applied for VAT registration by mistake

The form allows you to formally explain why VAT registration is not required.

When Does a Small Business Need to Submit a VAT5EXC Form?

You may need to submit a VAT5EXC form if:

  • Your taxable turnover is below the VAT registration threshold
  • You do not expect to exceed the threshold in the next 12 months
  • Your income is mainly VAT-exempt or outside the scope
  • Your company is dormant or has stopped trading
  • You registered for VAT in error

HMRC will normally tell you when a VAT5EXC form is required, either by letter or email.

What Information Is Required to Complete the VAT5EXC Form?

To complete the VAT5EXC form accurately, you will need:

1. Business Details

  • Business or company name
  • Company number (if limited company)
  • UTR (if applicable)
  • Trading and correspondence address

2. Turnover Information

  • Actual taxable turnover for the last 12 months
  • Expected taxable turnover for the next 12 months

⚠️ HMRC focuses on taxable turnover, not total income.

3. Business Activity Explanation

  • Nature of your business activities
  • Whether supplies are:
    • VAT-exempt
    • Outside the scope of VAT

4. Supporting Evidence (if requested)

  • Sales invoices
  • Bank statements
  • Management accounts

Providing clear figures and explanations reduces the risk of delays.

How Do I Fill Out the VAT5EXC Form Correctly?

To complete the VAT5EXC form correctly:

  1. Check your VAT threshold position carefully
    Use only taxable supplies.
  2. Be consistent with previous HMRC submissions
    Figures should align with:
    • VAT application
    • Corporation Tax or Self-Assessment
    • CIS or payroll records (if relevant)
  3. Clearly explain why VAT registration is not required
    Avoid vague wording—be factual and specific.
  4. Attach evidence if HMRC has asked for it
    This significantly speeds up processing.

Can I Authorise an Agent to Submit the VAT5EXC Form on My Behalf?

Yes. You can authorise an accountant or VAT agent to submit the VAT5EXC form on your behalf.

An authorised agent can:

  • Review your VAT position
  • Prepare and submit the VAT5EXC form
  • Communicate directly with HMRC
  • Respond to follow-up questions

This is strongly recommended if:

  • HMRC has already raised concerns
  • Your business has mixed VAT-exempt and taxable income
  • You want to avoid forced VAT registration

What Is the Deadline for Submitting the VAT5EXC Form in the UK?

There is no fixed statutory deadline, but:

  • HMRC usually sets a response deadline (often 14–30 days)
  • Missing the deadline can result in:
    • Automatic VAT registration
    • VAT backdated to an earlier date
    • Penalties and interest

Always respond within the timeframe stated in HMRC’s correspondence.

How Long Does It Take HMRC to Process a VAT5EXC Form?

Typical processing times are:

  • 2–4 weeks for straightforward cases
  • 4–8 weeks or longer if HMRC requests further evidence

Delays usually occur where:

  • Turnover figures are unclear
  • Explanations conflict with HMRC data
  • Supporting documents are missing

Are There Professional Services That Help With VAT5EXC Form Filing?

Yes. Specialist VAT accountants regularly assist businesses with:

  • Reviewing VAT registration eligibility
  • Preparing and submitting VAT5EXC forms
  • Handling HMRC correspondence
  • Resolving rejected or delayed VAT exclusions

Professional help is particularly useful for:

  • Construction businesses
  • Service-based SMEs
  • Startups and dormant companies
  • Businesses previously advised incorrectly

Common VAT5EXC Form Mistakes to Avoid

  • Using total income instead of taxable turnover
  • Submitting inconsistent figures
  • Missing HMRC deadlines
  • Failing to provide evidence when requested
  • Assuming HMRC will resolve discrepancies without explanation
