For most people, a tax refund doesn’t attract much attention. It tends to be the result of something relatively minor: an adjustment through PAYE, an allowance that wasn’t claimed, or a timing difference that has now been corrected.
The system reconciles, and the money comes back – and that is still the case, the vast majority of the time.
What has changed, however, is how some of these refunds are being generated.
Increasingly, they are not the result of a taxpayer identifying an issue or working through their position with an adviser, but of being approached by an unknown third-party, often online, with the suggestion that a repayment is waiting to be claimed.
The process is usually presented as quick and uncomplicated. Authority is granted, a claim is submitted, and a refund follows, but only later does the detail begin to matter.
A familiar service, approached differently
At one level, none of this is new; advisers have always helped clients recover overpaid tax, and there is nothing unusual about charging a fee based on the outcome.
Where the distinction begins to emerge is in how the claims themselves are prepared.
In a traditional setting, a refund would follow a review of records, a discussion of the individual’s circumstances, and a clear understanding of what is – and is not – allowable. That process takes time, and the outcome is usually grounded in evidence.
However, some of the newer business models take a different approach.
Rather than working through the details, they rely more heavily on standard categories, assumptions, or broadly applied percentages. From the outside, the figures appear reasonable enough. For the taxpayer, the experience is often straightforward – little involvement, and a quick result.
The difficulty is that what appears reasonable at a glance does not always reflect the underlying position.
Not all advisers are subject to the same standards
It is also worth recognising that not everyone offering tax services operates under the same level of oversight.
In the UK, anyone can describe themselves as an “accountant”, regardless of qualifications or regulatory status. By contrast, “chartered accountant” is a protected term, reserved for members of recognised professional bodies.
That distinction is not always clear in practice.
You may find some firms present themselves in a way that suggests a level of expertise or oversight that may not exist, while others provide little transparency around who is preparing the work or what standards are being applied.
This does not necessarily mean the advice is incorrect, but it does affect the level of assurance behind it, particularly where claims are prepared quickly and with limited explanation.
In some cases, potential issues only come to light once HMRC opens an enquiry, or, more rarely, when matters reach a Tribunal. A recent Tribunal case involving Welcome Accountancy Services highlighted how tax refund claims had been submitted on a basis that could not be supported when examined in detail, raising wider questions around oversight and the standards being applied.
Where claims start to come under pressure
Employment expenses are often where this approach becomes most visible.
The rules themselves are well established, but they leave less room for interpretation than many expect. For an expense to be deductible, it must be incurred wholly, exclusively and necessarily in the performance of employment duties. That wording is deliberate, and it sets a high threshold.
In practice, many everyday costs fall outside it.
Travel provides the clearest example: the journey between home and a permanent workplace, regardless of distance, is generally not allowable. Nor are the broader costs of maintaining employment, even where they feel closely connected to the role.
Despite this, some claims include substantial deductions for travel, professional fees, or other general categories of expense. When viewed in isolation, the numbers may not immediately appear unusual, but when considered in the context of the rules, they can be difficult to support.
One problem is that this distinction is not always obvious at the time the claim is made.
Why the issue doesn’t always surface immediately
The way HMRC processes returns plays a part in how these situations develop.
Given the volume of submissions received each year, there is a practical need to issue repayments efficiently. In many cases, refunds are processed before a detailed review takes place. For genuine claims, this is clearly beneficial as delays would serve little purpose.
However, it also means that not every claim is tested at the outset.
Where figures appear broadly credible, they may pass through the system without challenge. More detailed scrutiny often occurs later, when information is reviewed alongside other data or inconsistencies start to emerge over time.
By that stage, the repayment has already been received, and the question is no longer whether the claim should be made, but whether it can be justified.
Responsibility does not transfer with the work
One of the more uncomfortable aspects of these situations is where responsibility ultimately sits.
Even where a third party prepares and submits a return, the legal responsibility for its accuracy remains with the taxpayer. That position does not change based on who calculated the figures, their qualifications or how the claim was presented.
For many, this runs counter to expectation. If an adviser has been engaged, particularly one who presents themselves as experienced or qualified, it is natural to assume that accountability lies with them. In practice, HMRC will usually look to the individual first.
If questions are raised, it is the taxpayer who is expected to explain the position, provide evidence, and support the figures submitted on their behalf. Many of you will know that an HMRC investigation can prove costly, even if ultimately your figures are found to be in order.
When enquiries begin, the detail matters
An enquiry may start as a routine request for clarification, but it quickly becomes a question of evidence:
- How were the figures calculated?
- What do they relate to?
- What records support them?
These are not unreasonable questions, but they can be difficult to answer when the original claim was not supported by detailed documentation.
In some cases, records are incomplete; in others, they may not exist at all. There are also situations where the figures cannot realistically be reconciled with the taxpayer’s actual circumstances.
At that point, the position becomes more complex and can raise red flags with HMRC, potentially leading to:
- Return of refunds
- Interest charges
- Additional penalties
Depending on how HMRC views the behaviour behind the claim, what may have started as a relatively straightforward refund can evolve into a much more involved process.
Why this is becoming more visible
This is happening against the backdrop of a broader shift within the tax system, resulting in more complexity and a record tax take.
HMRC now has access to increasing amounts of data from third parties, including employers, financial institutions and digital platforms. At the same time, initiatives such as Making Tax Digital are moving reporting toward more frequent and structured submissions.
Taken together, these changes make inconsistencies easier to identify.
Claims that might previously have gone unnoticed are more likely to be picked up, particularly where patterns emerge across multiple returns or over several years. The direction of travel is clear: greater visibility, more data, and closer alignment between reported figures and underlying activity.
Recognising the warning signs
It is important to recognise that not all refund services present a risk. Many legitimate advisers provide valuable assistance in recovering overpaid tax.
However, certain features tend to appear more frequently in problematic cases:
- Promises of guaranteed or unusually large refunds are one example
- Claims based on fixed percentages, rather than individual circumstances, are another
- Limited discussion of the underlying position or a lack of clarity about how figures have been calculated
- Requests to use personal HMRC login details should be approached with particular caution
Individually, none of these points are conclusive. However, taken together, they usually indicate the claim hasn’t been prepared with the level of care required.
Taking a more considered approach
Where a refund is genuinely due, the process should be able to withstand scrutiny.
That typically involves understanding the taxpayer’s circumstances, reviewing supporting records, and applying the rules to the facts as they actually are. It is not always the quickest route, but it is the one that provides certainty.
In some cases, the outcome will be a repayment; in others, it may simply confirm that the original position was already correct. Both outcomes are valid.
The key point is that the position can be supported if it is ever questioned.
Conclusion
Tax refunds are a normal and necessary part of the system. They ensure that taxpayers do not pay more than they owe, and in most cases, they arise without issue.
The risk lies not in the refund itself, but in how it has been calculated.
A claim that appears straightforward at the outset may look very different when examined in detail. Where the underlying figures cannot be supported, the consequences tend to fall back on the taxpayer, regardless of who submitted the return.
If you have submitted a claim recently, or are unsure whether a refund you have received would stand up to scrutiny, it is worth reviewing the position now rather than waiting for HMRC to ask questions.
At Wilkins Southworth, we regularly help clients assess claims, correct positions where needed, and manage HMRC enquiries when they arise. Addressing these points early is almost always more straightforward than revisiting them later. In tax, as in most areas of life and business, certainty is rarely found in shortcuts.
