Partial Exemption VAT Explained (UK Guide for Businesses)
If your business makes a mix of VAT-taxable and VAT-exempt sales, understanding partial exemption is essential. Getting it wrong can mean either losing out on VAT you could reclaim or facing unexpected repayments to HMRC.
In this guide, we break it down in plain English so you know what it means, how it works, and what to watch out for.
What is Partial Exemption?
Partial exemption applies when your business has both taxable and exempt income.
Taxable supplies: Sales where VAT is charged (e.g. standard-rated or zero-rated goods/services)
Exempt supplies: Sales where no VAT is charged (e.g. certain financial services, property rental, education)
👉 The key issue:
You cannot reclaim all the VAT you incur on your costs if some of your income is exempt.
Why It Matters
Partial exemption directly affects how much VAT you can recover on expenses.
If not handled correctly, you could:
Miss out on legitimate VAT refunds
Overclaim VAT and face penalties
Create compliance risks during HMRC inspections
How VAT Recovery Works
To work out how much VAT you can reclaim, HMRC requires a 3-step process:
1. Attribution of Costs
You must split your VAT on expenses into three categories:
a) Directly related to taxable income
Example: materials used for a VATable service
✅ VAT is fully recoverable
b) Directly related to exempt income
Example: costs linked to exempt property rental
❌ VAT is not recoverable
c) Mixed-use costs (overheads)
Example: rent, utilities, accountancy fees
⚖️ VAT is partially recoverable
2. Apportionment (The Partial Exemption Calculation)
For mixed-use costs, you calculate how much VAT you can reclaim using this standard formula:
Recoverable %= Taxable Income / (( Taxable Income + Exempt Income)*100)
This percentage is then applied to your overhead VAT.
📌 Example:
If 70% of your income is taxable, you can typically recover 70% of VAT on shared costs.
3. Annual Adjustment
Throughout the year, you may use estimates. At the end of your VAT year, you must:
Recalculate using actual figures
Adjust for over- or under-claimed VAT
The De Minimis Rule (A Key Opportunity)
There’s an important exception called the de minimis rule.
If your exempt-related VAT is small enough, you may be able to recover all your VAT—even on exempt activities.
You qualify if BOTH apply:
Exempt input VAT is under £625 per month on average (£7,500 per year)
AND it is less than 50% of your total input VAT
✅ If you qualify, your business is treated as fully taxable for VAT recovery purposes.
Real-Life Scenario
Imagine a business with:
£300,000 taxable income
£100,000 exempt income
That means:
75% taxable
25% exempt
👉 Result:
75% of VAT on overheads can be reclaimed
VAT on exempt-related costs is normally blocked
But if the exempt VAT is small enough under the de minimis rules, you may recover everything.
Common Mistakes to Avoid
Many businesses unknowingly get partial exemption wrong. Common issues include:
Not separating costs properly
Using incorrect percentages
Forgetting the annual adjustment
Missing out on the de minimis rule
Applying the standard method when a better method exists
Can You Use a Different Method?
Yes. If the standard calculation doesn’t fairly reflect your business, you can apply for a special method with HMRC.
This is often useful where:
Income doesn’t reflect actual usage (e.g. property businesses)
Cost structures are unusual
The standard method produces distorted results
Planning Opportunities
With the right advice, partial exemption can be actively managed, not just complied with.
Opportunities include:
Timing expenditure to maximise recovery
Structuring activities to improve VAT position
Monitoring thresholds to benefit from de minimis
Reviewing property and finance arrangements
