When does a hobby become a business

Many people start an activity as a hobby, perhaps selling handmade goods online, offering occasional services, or generating small amounts of additional income from spare capacity. Over time, what begins as a leisure pursuit can evolve into something that looks increasingly commercial. This raises an important question, when does a hobby become a business for tax purposes?

HMRC does not rely on a single test. Instead, it considers a number of indicators commonly referred to as the badges of trade. These are established principles derived from case law and used to assess whether an activity amounts to trading rather than a private pastime.

One important factor is profit motive. A genuine intention to make a profit suggests the activity is more likely to be treated as a business. Occasional sales at a loss may not prevent trading status, but consistent attempts to generate surplus income may indicate commercial intent.

Frequency and repetition are also relevant. Selling items regularly, particularly where the activity is organised and ongoing, suggests a trading activity rather than the disposal of personal possessions. A one off sale is unlikely to be regarded as trading, but repeated transactions may indicate business behaviour.

The nature of the asset can also provide insight. Items acquired specifically for resale, or goods that are produced with the intention of selling at a profit, are more likely to fall within the definition of trading. By contrast, selling unwanted personal items is less likely to attract tax consequences.

The way the activity is organised can also be important. Keeping records, maintaining a website, marketing products or services, or investing in equipment may indicate a structured commercial approach. These factors often demonstrate that the activity is being conducted in a business-like manner.

Another consideration is the length of ownership. Assets held for a short period before resale may indicate trading, whereas items owned for personal enjoyment over a longer period may not.

Where activities begin to generate regular income, it is sensible to review whether registration for Self-Assessment may be required. Expenses incurred wholly and exclusively for business purposes may become deductible, but income will also become taxable.

For many individuals, the transition from hobby to business happens gradually. Early awareness of the badges of trade can help avoid unexpected tax liabilities and ensure that appropriate records are maintained from the outset.

If you are unsure whether your activity may be regarded as trading, a review can help clarify your position and identify any planning opportunities.

Price gouging and the governments new response

Recent global instability, particularly tensions affecting oil and energy supply chains, has increased concerns about price gouging, where businesses take advantage of shortages or uncertainty to impose unjustified price increases. In response, the UK government has announced new measures intended to protect consumers and ensure markets continue to operate fairly.

Price gouging generally occurs when businesses increase prices significantly beyond what can reasonably be justified by increases in underlying costs. This behaviour often becomes more visible during periods of crisis, when supply chains are disrupted, demand becomes volatile, and consumers have limited alternatives. Energy markets are particularly sensitive to global events, as oil and gas prices can react rapidly to geopolitical developments.

In March 2026, the Chancellor set out plans to introduce an anti-profiteering framework aimed at ensuring regulators can act more quickly where unfair pricing practices are suspected. The government has indicated that the Competition and Markets Authority may receive targeted, time limited powers to investigate and address excessive price increases if evidence of price manipulation emerges.

The measures are designed to address concerns that businesses may attempt to exploit uncertainty linked to conflict in the Middle East and resulting pressures on energy and fuel prices. The government has emphasised that it will not hesitate to intervene where pricing behaviour appears inconsistent with normal competitive market conditions.

Alongside regulatory action, the government is also considering structural measures to improve long term price stability. These include accelerating investment in domestic energy generation, particularly nuclear power, and reviewing import tariffs on selected goods to reduce pressure on household budgets. Improving energy security is intended to reduce reliance on volatile global markets and limit the risk of sudden price spikes in future years.

Regulators are already increasing monitoring of fuel and heating oil markets, with enforcement action expected where breaches of consumer protection law are identified. Increased transparency in pricing is expected to play an important role in discouraging opportunistic behaviour by suppliers.

For businesses, the key message is that pricing strategies should remain commercially justifiable and capable of explanation if challenged. Sudden increases in margin during periods of market stress may attract regulatory scrutiny, particularly where customers appear to have limited alternatives.

For consumers, the proposed framework provides reassurance that the government intends to take action where markets fail to operate competitively. Over time, improved energy security and more active regulatory oversight may help reduce the frequency and severity of price shocks affecting households and businesses.

MTD for Income Tax – are you affected

If you have not yet checked whether you need to use Making Tax Digital (MTD) for Income Tax, now is the time to urgently see if you are affected. The Income Tax reporting requirements for some self-employed individuals and landlords will change significantly from 6 April 2026. MTD for Income Tax changes the traditional annual self-assessment process to a new digital record-keeping and quarterly updates process submitted through recognised software.

From April 2026, those with qualifying income over £50,000 will be required to maintain digital records and submit quarterly updates of trading or property income and expenses. From April 2027, the threshold will reduce to £30,000, and in April 2028 it will further reduce to £20,000. 

A full tax return will still be required by the following 31 January after the tax year i.e. the first MTD for Income Tax return, covering the 2026-27 tax year, will be due by 31 January 2028.

MTD aims to reduce errors, improve efficiency, and support business productivity. HMRC estimates that around 860,000 taxpayers will join in 2026, with more joining in 2027. 

The system also provides exemptions for those unable to go digital and offers accessible software solutions. Taxpayers joining MTD for Income Tax in April 2026 will not receive penalty points for late quarterly updates for the first 12 months. This will allow them time to adapt to the new system.

Companies House blunder

A Companies House blunder has raised concerns after a flaw in the WebFiling service briefly exposed sensitive company data. The issue, identified on 13 March 2026, meant that a logged-in user could potentially access and amend limited details of another company by carrying out a specific sequence of actions.

Companies House has stated that this system vulnerability was not available to the general public. Only users with authorised access codes who were already logged into the system could have exploited it. Nevertheless, the nature of the flaw meant that certain private information, such as dates of birth, residential addresses and company email addresses may have been visible. There was also a risk that unauthorised filings, including accounts and changes to director details, could have been submitted on another company’s record.

After identifying this issue, Companies House shut down the WebFiling service at 13:30 on 13 March to investigate. Following independent testing, the system was restored at 09:00 on 16 March. Companies House has said that passwords and identity verification data were not compromised, and that existing filed documents, such as accounts or confirmation statements, could not be altered.

The issue is believed to have arisen from a WebFiling systems update in October 2025. It has been reported to both the Information Commissioner’s Office and the National Cyber Security Centre.

Companies are now being urged to review their registered details and filing history carefully. While no confirmed misuse has been reported so far, Companies House is continuing to investigate. If a company has a concern, it should raise a complaint via the Companies House complaints page at www.gov.uk/government/organisations/companies-house/about/complaints-procedure and include evidence to describe the issue.

Tax allowances frozen for 2026-27

It was confirmed as part of the Autumn Budget that the Income Tax thresholds will continue at their current levels for a further three years, extending the freeze until April 2031. This means that most tax allowances are to remain frozen for 2026-27 and beyond.

As a result, the personal allowance will stay at £12,570, while the higher rate threshold will remain at £50,270 for taxpayers across most of the UK (with different thresholds applying in Scotland). National Insurance thresholds will also remain fixed over the same period.

Keeping these thresholds unchanged means that many taxpayers will gradually pay more tax as their earnings increase over time. This effect, commonly known as fiscal drag, occurs when wages rise but tax bands do not. As incomes grow due to inflation or pay increases, a larger portion of earnings becomes taxable, and more people move into higher tax brackets.

In practical terms, the continued freeze is likely to push increasing numbers of taxpayers into the 40% higher rate band and, for some, the 45% additional rate band. Others who previously earned below the personal allowance may also begin paying Income Tax for the first time. Although tax rates themselves remain unchanged, the overall tax burden rises as more income becomes subject to tax.

Fiscal drag is influenced by several factors, including government policy on tax thresholds, inflation levels and wage growth. In periods of rising wages or high inflation, the impact of frozen thresholds becomes more pronounced. For taxpayers the impact of fiscal drag effectively operates as a stealth tax over time.

Changes to reporting of BiKs

Mandatory payrolling of benefits in kind (BiKs) and taxable employment expenses will be introduced from 6 April 2027. This represents a major change in reporting and means that for most benefits, the annual P11D form will no longer be required from the start of the 2027-28 tax year.

The requirement to report Income Tax and Class 1A National Insurance on most BiKs through Real Time Information (RTI) was originally due to start on 6 April 2026 but has been delayed until 6 April 2027 to allow additional time for employers, payroll professionals, software providers and agents to prepare.

The deadline to register for the current voluntary payrolling service for the 2026-27 tax year is 5 April 2026. After this, the service will close in preparation for the introduction of mandatory payrolling. 

From April 2027, employers will report BiKs and expenses via the Full Payment Submission (FPS), aligning reporting with the process currently used for reporting salaries. The number of RTI fields will be expanded to reflect the data currently captured through P11D and P11D(b) forms. Employers will also have the option to payroll employment-related loans and accommodation on a voluntary basis.

To support implementation, HMRC will waive penalties for inaccuracies related to mandatory payrolling for 2027-28, provided there is no evidence of deliberate non-compliance. However, existing late filing, late payment penalties and interest will continue to apply.

HMRC has confirmed that its Basic PAYE Tools software will also be updated to support payrolling of benefits in kind from April 2027.

External business threats and how planning can help counter them

External risks can affect even well managed businesses. Many threats arise outside the control of business owners, yet they can have a significant impact on profitability, cash flow and long term stability. Economic change, regulatory developments, market disruption and supply chain pressures can all create uncertainty. Forward planning allows businesses to prepare for these risks and respond with greater confidence.

Economic uncertainty

Changes in interest rates, inflation levels and consumer demand can quickly alter trading conditions. Rising costs may reduce margins, while reduced customer spending may affect turnover. Businesses that monitor economic trends and prepare financial forecasts are better placed to identify pressures early. Planning allows time to review pricing policies, reduce unnecessary expenditure and strengthen cash reserves where appropriate.

Legislative and regulatory change

Tax legislation, employment law and compliance requirements frequently evolve. Businesses that do not keep pace with change may face unexpected costs or administrative burdens. Examples include developments in Making Tax Digital, changes to employment rights, or adjustments to tax reliefs and allowances.

Planning enables businesses to anticipate regulatory developments and assess the likely financial impact. Early preparation reduces disruption and allows time to consider alternative structures or processes where appropriate.

Supply chain disruption

Recent global events have demonstrated how supply chains can be affected by political tensions, transportation difficulties and shortages of key materials. Businesses reliant on a limited number of suppliers may face delays or increased costs.

Contingency planning may include identifying alternative suppliers, reviewing stock levels or renegotiating delivery arrangements. Diversifying supply sources can improve resilience and reduce dependency on any single provider.

Technology and market disruption

Technological change continues to reshape many industries. New entrants, digital platforms and automation can alter customer expectations and competitive pressures. Businesses that review their market position regularly are better placed to identify opportunities as well as risks.

Planning may involve investment in systems, staff training or revised marketing approaches. Understanding customer needs and monitoring competitor activity supports more informed decision making.

Cash flow pressure

Cash flow remains one of the most common causes of business difficulty. External factors such as rising costs or delayed customer payments can place strain on working capital.

Preparing cash flow forecasts allows businesses to anticipate shortfalls and consider funding options where required. Early discussions with lenders or advisers can provide greater flexibility than reactive decision making.

Conclusion

External threats are an unavoidable aspect of running a business. While risks cannot always be prevented, their impact can often be reduced through careful planning. Regular review of financial performance, regulatory developments and market conditions helps businesses respond more effectively to change.

A structured planning approach supports resilience and improves the ability to make timely decisions. Businesses that take time to assess potential risks are often better positioned to maintain stability and identify opportunities for sustainable growth.

What the new HMRC website does not provide

The launch of HMRC’s Tax Confident website represents a clear attempt to simplify the UK tax system and help individuals better understand their obligations. The site is structured around real life situations such as starting work, running a small business, or approaching retirement, and aims to present tax concepts in plain English without technical jargon.

While this is a positive development, the new platform also highlights an important point. The website is designed primarily to improve understanding of tax compliance, rather than to help taxpayers actively minimise their liabilities. In practice, there are several areas where the website does not provide the depth or perspective that taxpayers often need.

Limited support for tax planning

The website explains how tax works but does not generally explore how taxpayers might structure their affairs more efficiently. For example, it provides basic guidance on Self-Assessment, Income Tax and National Insurance, but does not typically highlight planning opportunities or alternative approaches that could legitimately reduce tax liabilities.

This distinction is important. Understanding how tax operates is different from understanding how to plan for tax. Decisions about timing of income, use of allowances, or selection of tax regimes often require comparison of options and forward looking judgement.

High level guidance rather than technical depth

The site focuses on core principles such as Personal Allowance, payslips, and how different types of income are taxed.

However, many practical tax issues involve interaction between multiple rules. Areas such as capital allowances, pension contribution planning, profit extraction strategies, or VAT scheme selection often require more detailed analysis than the website provides.

Simplification improves accessibility but inevitably reduces technical coverage.

Limited identification of overlooked reliefs

Many legitimate tax reliefs depend on taxpayers knowing they exist in the first place. Reliefs such as Marriage Allowance, Rent a Room relief, or the Trading Allowance are not always prominently highlighted within general guidance material.

HMRC campaigns traditionally focus on encouraging correct reporting and timely filing of returns, rather than prompting individuals to claim every available relief.

As a result, taxpayers relying solely on general guidance may not identify opportunities to reduce liabilities.

Focus on compliance rather than optimisation

HMRC’s wider digital strategy aims to help taxpayers manage their affairs through online services and apps, supporting increased self-service.

This supports efficiency and accuracy, but the emphasis remains on ensuring the correct tax is paid, rather than helping taxpayers determine the most efficient structure for their affairs.

The distinction between compliance and optimisation is significant. Compliance ensures obligations are met. Planning considers whether the outcome could be improved within the rules.

Not a substitute for professional advice

The website is best viewed as an entry level educational resource. It is helpful for understanding terminology, responsibilities and deadlines, but it does not replace the analytical support typically provided by professional advisers.

Tax legislation is complex and frequently changing. Decisions often involve judgement about risk, interpretation of rules, and consideration of future events.

Conclusion

The Tax Confident website is a useful addition to HMRC’s educational resources and should improve baseline understanding of the UK tax system. Its plain English approach and life stage structure make tax more accessible to a wider audience.

However, the website does not aim to provide strategic tax planning guidance, detailed technical analysis, or proactive identification of relief opportunities. Taxpayers who rely solely on general guidance may therefore meet their compliance obligations but still miss legitimate opportunities to improve their tax position.

For many individuals and businesses, professional advice continues to play an important role in ensuring that tax affairs are both compliant and efficient.

Are you affected by and ready for MTD for Income Tax

Making Tax Digital for Income Tax is no longer a distant reform. From April 2026, next month, many sole traders and landlords will be required to comply with a new system of digital record keeping and quarterly reporting. The key question for many is simple. Are you affected, and are you ready?

The rules will initially apply to individuals with combined business and property income exceeding £50,000. The base year for meeting the £50,000 target is 2024-25. This threshold is based on gross income, not profit, which means more taxpayers will be brought into the regime than might be expected. A second phase is due to follow from April 2027, extending the requirements to those with income above £30,000.

If you fall within scope, the way you manage your tax affairs will change significantly. Annual Self-Assessment returns will be replaced by a requirement to maintain digital records and submit quarterly updates to HMRC. These updates will provide a summary of income and expenses, followed by an end of period statement and a final declaration.

For many, the biggest adjustment will be behavioural rather than technical. Businesses that are used to reviewing their figures once a year will need to move towards a more regular and disciplined approach. Record keeping will need to be timely, accurate, and supported by compatible software.

There are also practical considerations. You will need to choose suitable software, ensure that your records are complete and digital, and understand how the quarterly reporting process works. For landlords, this may involve separating property income streams more clearly. For sole traders, it may require changes to how expenses are tracked and categorised.

The benefits should not be overlooked. More frequent reporting can provide better visibility over business performance and tax liabilities. This can support improved decision making and reduce the risk of unexpected tax bills.

However, there are risks for those who delay. Late preparation may lead to errors, missed deadlines, and increased compliance costs. It may also place additional pressure on your adviser at a time when demand for support is likely to be high.

Now is a good time to review your position. Consider whether you will be within scope, assess your current record keeping processes, and take advice where needed. Early action will make the transition smoother and ensure that you remain compliant from the outset.

Making Tax Digital represents a significant shift in how tax is reported in the UK. With the first phase now imminent, preparation is no longer optional, it is essential.
