HMRC’s New Reporting Rules

For many small business owners, moving money between themselves and their company is simply part of day-to-day financial management.

A dividend declared at year-end, a director’s loan to smooth cash flow, reimbursed expenses or the occasional transfer of assets. These are not unusual transactions – they are often essential to how owner-managed businesses operate.

But under new proposals from HMRC, these routine movements could soon face far greater scrutiny.

A recent consultation suggests that “close companies” – broadly defined as businesses controlled by five or fewer individuals – may be required to report detailed information on all transactions between the company and its participators. This includes cash withdrawals, loans, debts, dividends, distributions and asset transfers.

On the surface, this may seem like a logical step toward greater transparency. In practice, however, it raises a more complex question: is this a proportionate response to tax risk, or an additional layer of compliance for already stretched business owners?

What exactly is being proposed?

The core of the proposal is relatively straightforward.

HMRC is seeking greater granularity into how money flows between small companies and their owners. Under the new rules, close companies could be required to disclose a wide range of financial interactions, including:

• Cash withdrawals by directors or shareholders
• Loans to and from participators
• Outstanding debts
• Dividend payments and other distributions
• Transfers of assets between the company and individuals

In effect, HMRC would move closer to a position where most, if not all, financial relationships between a company and its owners are routinely reported.

For businesses already maintaining detailed records, this may seem like an extension of existing obligations. For many others, it represents a shift toward far more structured and formalised reporting.

HMRC’s rationale: Tackling the tax gap

HMRC’s justification for these proposals is clear: reducing tax avoidance (or the “tax gap” as it is commonly referred to).

According to its estimates, up to 60% of the UK’s tax gap – the difference between expected and actual tax receipts – is attributed to small businesses. Close companies, in particular, are seen as having the flexibility to structure financial arrangements in ways that reduce tax liabilities, ranging from entirely legitimate planning to more aggressive avoidance.

From a policy perspective, the argument is simple. If the perceived risk sits within smaller, owner-managed businesses, then increasing transparency in that area should, in theory, improve compliance and reduce lost revenue.

However, the headline figure – that small businesses account for the majority of the tax gap – warrants closer examination.

Where does the tax gap really arise?

The concept of the tax gap is often presented as a single figure, but in reality, it comprises several distinct components.

These include:

• Income that is never declared (the so-called “hidden economy”)
• Errors in tax returns (often unintentional)
• Deliberate evasion
• Legal but complex tax structuring

While small businesses undoubtedly feature within this mix, many would question whether compliant, owner-managed companies – those already engaging with accountants and submitting returns – represent the core of the issue.

A significant proportion of the gap is widely understood to arise from income that is never reported, rather than from businesses operating within the system. At the other end of the spectrum, large multinational structures, including transfer pricing arrangements, have historically attracted scrutiny due to their ability to shift profits across jurisdictions.

This raises a broader question of focus. If the objective is to reduce the tax gap, is increasing reporting requirements for compliant small businesses the most effective route, or simply the most administratively accessible one?

Strip away the headline figures, and there is a legitimate question as to whether small businesses are simply an easy target.

A growing concern among small businesses

Unsurprisingly, the reaction from the small business community has been cautious.

The Federation of Small Businesses (FSB) has already warned that the proposals risk increasing compliance costs and further complicating an already challenging system. For many business owners, the concern is not about paying the correct amount of tax; it is about the cumulative burden of navigating the rules.

Unlike larger organisations, small companies do not have internal tax departments or dedicated compliance teams. The owner often handles financial management alongside running the business, with periodic support from external advisers.

In this context, even relatively modest increases in reporting requirements can have a disproportionate impact.

There is also a wider frustration that will be familiar to many: dealing with HMRC is rarely straightforward.

Queries can take months, sometimes years, to resolve, and guidance is not always clear or accessible to those without specialist knowledge.

Adding further layers of reporting, without addressing these underlying issues, risks compounding the problem rather than solving it.

The practical impact: What this could mean in reality

While the proposals are still at the consultation stage (closing on the 10th June), the potential implications for small businesses are significant.

Increased administrative burden

At a basic level, more reporting means more work and ultimately, higher cost.

Transactions that may previously have been recorded informally, or simply understood between the business and its adviser, could now require detailed documentation and categorisation. This includes ensuring that all movements between the company and its participators are clearly tracked and justified.

For some businesses, this will require changes to internal processes. For others, it may mean introducing entirely new systems.

Higher professional costs

Greater complexity inevitably leads to greater reliance on professional advice. Accountants will need to review additional data, ensure compliance with evolving rules, and potentially spend more time resolving discrepancies. 

For business owners, this translates into higher fees and more frequent engagement with advisers. While this may be manageable for established companies, it is a different proposition for smaller or early-stage businesses operating with tighter margins.

Increased risk of enquiries and disputes

More data does not necessarily mean more clarity. In fact, increased reporting can create more opportunities for inconsistencies, particularly where transactions are complex or span multiple tax periods. Even minor discrepancies between reported figures and HMRC’s interpretation could trigger enquiries.

Given existing delays within HMRC systems, these enquiries can be lengthy and resource-intensive. What might begin as a routine query can quickly turn into a prolonged process, creating uncertainty and additional costs.

A shift in behaviour

Perhaps the most subtle impact is behavioural.

Faced with increased scrutiny, some business owners may choose to simplify their financial interactions with their company. This could mean avoiding director’s loans, altering dividend strategies, or reducing flexibility in managing cash flow.

While this may reduce perceived risk, it can also lead to less efficient financial decision-making – particularly where existing structures are entirely legitimate and appropriate.

Striking the right balance

There is a reasonable argument for improving transparency – there is little disagreement on the principle – but is this the right way, the best way?

Requiring businesses to report certain transactions – predominantly those involving loans or significant cash movements – could help HMRC identify areas of genuine concern. In isolation, this is unlikely to be controversial. The challenge lies in how far the rules extend.

There is a clear distinction between targeted reporting designed to highlight risk and a broad requirement to capture all interactions between a company and its owners. The former may be proportionate. The latter risks becoming overly burdensome, particularly when layered onto an already complex system.

As one tax expert noted in response to the proposals, reporting certain transactions may have minimal impact. Requiring businesses to fully engage with the technical rules governing close companies, however, could be far more demanding.

Part of a wider trend

Those in business today will be well aware that these proposals do not exist in isolation.

Over recent years, HMRC has been steadily moving toward greater data collection and digital reporting. Initiatives such as Making Tax Digital reflect a broader shift toward real-time visibility of taxpayer activity, supported by software and automated systems.

From this perspective, the proposed changes are consistent with a longer-term direction of travel. The expectation is clear: more frequent reporting, greater transparency, and fewer gaps between economic activity and tax reporting.

For business owners, this reinforces the need to adapt systems, processes and habits. All of which may have been sufficient in the past, but are unlikely to remain so in the future.

What should business owners be doing now?

While the rules are not yet finalised and the proposals may be watered down, there are practical steps worth considering:

• Review how funds move between you and your company
• Ensure transactions are clearly documented and supported
• Consider whether existing processes would stand up to increased scrutiny
• Speak with your accountant about potential changes

Preparing early is likely to be far less disruptive than reacting once new requirements are introduced.

Conclusion

HMRC’s objective of reducing tax avoidance and improving transparency is understandable. However, the route to achieving it matters.

For many small businesses, the concern is not the principle of compliance, but the cumulative weight of additional reporting, rising costs and ongoing uncertainty. There is a risk that measures designed to target a minority could impose a broader burden on those already operating within the rules.

The real test will be whether these proposals strike the right balance: addressing genuine areas of risk without turning routine business activity into a disproportionate compliance exercise.

If you are unsure how these potential changes could affect your business, or whether your current structure would withstand increased scrutiny, it may be worth reviewing your position now rather than waiting for the rules to take effect.
