Many are often without realising it.
Partial exemption remains one of the more technical areas of VAT. For businesses that generate both taxable and exempt income, the rules around recovery can quietly limit the amount of VAT reclaimed or lead to unintentional overclaims. In both scenarios, the financial impact is significant.
What is partial exemption?
In standard VAT recovery, a business reclaims input VAT on costs related to VATable supplies. But where a business makes both taxable and exempt supplies, it becomes “partially partly exempt.” That means not all input VAT can be reclaimed only the portion that relates to taxable activity.
To manage this, businesses must use a method to apportion VAT on overheads that serve both taxable and exempt income. This is known as a partial exemption method. HMRC provides a default approach, known as the standard method, which calculates recoverable VAT based on the ratio of taxable to total turnover.
However, this method often fails to reflect commercial reality, particularly in businesses with large, irregular, or high-value exempt income that doesn’t reflect actual resource use. In these cases, the standard method can significantly understate the VAT that should be recoverable.
Note that charities and others who have “non-business” activities may also have to perform additional calculations on the basis VAT is not normally reclaimable on non-business activities.
Special methods and why they matter
Where the standard method produces a distorted or unfair result, businesses can apply for a special method – a bespoke VAT recovery formula tailored to how they operate. It may be fairer to use cost allocation, floor space, headcount, or transaction counts rather than turnover alone. Special methods must be pre-approved by HMRC.
It is important that the method is as straightforward to operate (and for HMRC to understand and check) as possible, while still giving a fair and reasonable result.
These special methods are critical for ensuring fairness and maximising VAT recovery, especially in sectors such as:
- Land and Property
- Finance and leasing
- Education and training
- Healthcare/Welfare
Agreeing on a special method can take time, but the upside, particularly where costs are substantial, can be significant.
The De Minimis rule
Not all exempt businesses are restricted in recovering VAT. HMRC’s de minimis rule allows full input VAT recovery for partly exempt businesses where total exempt input VAT is below £625 per month (on average) and also less than 50% of total input tax. If a business qualifies, it is treated as fully taxable for VAT recovery purposes.
However, this rule is often misunderstood or overlooked, and incorrect application can lead either to over-claiming or to needlessly restricted recovery.
Smaller businesses may be able to use simplified tests.
Even if a business was de minimis in the previous year, it will always be necessary to check for de minimis at least annually and generally, quarterly. A common mistake is assuming historic qualification continues indefinitely when even a small shift in costs or income can change the outcome.
Why a one-time setup isn’t enough
Partial exemption is not a one-and-done exercise. Business models evolve. Income streams diversify. Property portfolios grow. If your VAT method hasn’t been reviewed in several years or if it was originally chosen based on simplicity rather than accuracy, it may no longer reflect how your business actually operates.
This misalignment becomes especially costly in businesses with significant overheads. Rent, technology platforms, marketing, and professional services often represent substantial VAT-bearing costs that, if misallocated, erode cash flow unnecessarily.
Moreover, changes in exempt activity, even temporary ones, can materially affect recovery rates. For example, a property company with a spike in non-qualifying rental income could find that its reclaimable VAT drops significantly under the standard method, even though operational activity remains stable.
What’s at risk
Mismanaging partial exemption exposes businesses to two key risks:
- Over-recovery of VAT, which may prompt HMRC queries, assessments, and penalties
- Under-recovery of VAT, which creates a silent drain on profitability over time
Neither outcome supports growth or confidence in reporting. A method that was once “good enough” may now be inefficient or simply wrong.
What you should do now
If your business makes exempt supplies, has complex cost structures, or hasn’t revisited its VAT recovery method in recent years, a detailed review is important.
Understanding how costs are incurred, how income is structured, and how recovery is calculated requires careful analysis not only of your accounts, but of your operating model and future plans.
In this area of VAT, getting it right isn’t about box-ticking. It’s about making sure your business isn’t paying more tax than it should and isn’t taking unnecessary risks with HMRC.
If you’re unsure whether your current method still reflects your business, or if you want clarity on what more might be recoverable, now is the time to ask the question. Contact Steve Chamberlain or contact us for more information
