HMRC is currently contacting certain sole traders by email to reiterate the importance of adjusting business expenses for personal use.

The email explains:

• why personal use must be adjusted on your self-assessment tax return; and
• what you need to do if your business expenses cover business and personal use.

The email also includes links to GOV.UK for more detailed information on personal use adjustments and allowable expenses. This is a genuine email that HMRC recently sent (from 20 October 2025 up to and including 7 November 2025).

This is an important reminder for sole traders. In general, if sole traders use something for both business and personal reasons, they can only claim allowable expenses for the business costs.

However, there are simplified arrangements available to sole traders for claiming a fixed rate deduction for certain expenses where there is a mix of business and private use. The simplified expenses regime is not available to limited companies or business partnerships involving a limited company.

Simplified flat rates can be used for working from home and for the business costs of vehicles. This method saves having to calculate the proportion of personal and business use.

The current monthly flat rates are based on the amount of business use of the home:

• 25 to 50 hours worked per month can claim – £10
• 51 to 100 hours worked per month can claim – £18
• 101 or more hours worked per month can claim – £26

Under simplified expenses, there are the following flat rates per mile available. These rates can be used instead of working out the actual costs of buying and running your vehicle, e.g. insurance, repairs, servicing, fuel.

• Cars and goods vehicles first 10,000 miles – 45p
• Cars and goods vehicles after 10,000 miles – 25p
• Motorcycles – 24p

Whilst using the flat rates is not compulsory, once a decision is made to use the simplification for a specific vehicle this must continue to be used for a vehicle as long as that vehicle is used for business purposes.

We would be happy to help you ascertain whether using simplified expenses or claiming based on actual costs incurred is more beneficial for your business.

For many small business owners, the focus is on day-to-day operations. However, building long-term value is just as important, whether your aim is to sell in the future, attract investors, or secure better financing.

Focus on profitability and cash flow
Strong profits are essential, but reliable cash flow is often more important to potential buyers or lenders. Keep tight control over expenses, reduce debtor days, and ensure pricing reflects the value you provide.

Develop recurring revenue
Income that is predictable and repeatable, such as subscription models or service contracts, increases business stability and value. It also makes forecasting more accurate and planning easier.

Strengthen your customer base
Avoid over-reliance on one or two major customers. A broad, loyal client base reduces risk and makes your business more attractive to others.

Build a strong management team
A business that depends too heavily on its owner can be harder to sell and less valuable. Train and empower staff so that the business can operate smoothly without you.

Protect your brand and processes
Invest in your reputation, intellectual property, and efficient systems. Documenting processes and having clear contracts with suppliers and customers adds professionalism and reduces uncertainty.

Plan ahead
Value is built over years, not months. Regularly review your strategy and financial performance and seek advice from your accountant to ensure every decision supports long-term growth.

Many business gifts and hospitality costs are not tax-deductible under current rules.

Entertainment expenses including providing hospitality and business gifts are common, but the taxation of these expenses is strictly governed by HMRC.

For businesses carrying on a trade, HMRC legislation generally prohibits tax deductions for client entertainment. If an employee receives a dedicated allowance or is reimbursed specifically for entertaining clients, the expense is generally disallowed when calculating the employer's tax liability.

Meals consumed by the employee during valid entertaining occasions are typically not taxed separately. But if entertainment is deemed personal or social in nature for instance, entertaining personal friends or business acquaintances then the reimbursement becomes taxable income for the employee. Reciprocal business entertaining between business acquaintances that lacks a clear commercial purpose also falls into this category even if some business topics happen to be discussed.

Where an employer provides a round sum allowance not explicitly for entertaining, and the employee uses it for such purposes, tax liability may instead fall on the employee. This includes not only the direct cost of entertaining but also any incidental expenses such as transport or venue hire.

Entertainment includes hospitality and business gifts, except for free samples used to advertise to the general public. Gifts that clearly display an advertisement for the donor may qualify for a limited exemption. However, this exemption does not apply to gifts of food, drink, tobacco, or vouchers, and the total cost per recipient must not exceed £50 per year.

Anyone claiming an exemption for entertaining expenses should keep clear records detailing the amount spent, who was entertained and the business reason behind the expense to support any claim.

Running more than one self-employed business? HMRC will not always treat them as separate. Whether they are taxed as one combined trade or multiple depends on how your activities relate to each other. It is not a matter of choice, it is about how your business is run in practice. Get it right to avoid costly mistakes.

When someone has more than one self-employed income, one of the key issues to consider is whether to combine all profits under a single business activity or treat each separately. This depends on the nature and relationship of the activities. HMRC’s manuals set out three possible scenarios:

1. Separate Trades

If the new activity is run independently, with different staff, stock, or customers, it is treated as a separate trade. This means each business is taxed individually, and the commencement rules apply to the new one. No merging takes place unless operations later combine in substance.

2. A New Single Trade

If the new activity transforms the original business significantly, so much so that the old trade effectively ends, then both are treated as forming a new trade. The cessation rules apply to the original trade, and commencement rules apply to the new, combined business.

3. Continuation of Existing Trade

If the new activity merely expands the existing business without fundamentally changing its nature, it is treated as a continuation. Profits are combined and taxed as one ongoing trade, with no change in basis.

Understanding whether activities form one trade or multiple is crucial for correct tax treatment. It’s not just a matter of choice. It also depends on the facts and how the businesses operate and interact.

We would be happy to help you review the structure of your business to ensure compliance with HMRC guidance and avoid unexpected tax consequences.

HMRC has launched a campaign targeting informal money transfer networks like Hawala, aiming to combat money laundering and protect communities. Businesses must register for AML supervision or risk fines, prosecution, or closure.

It is estimated that some £2 billion is laundered annually through these networks in the UK. This is a practice that is exploited by criminals to conceal the proceeds of serious organised crime.

These networks, often used by diaspora communities to send money abroad, rely on informal, trust-based systems like Hawala. These systems allow money to be transferred without crossing borders physically, relying instead on local trust networks between operators, or Hawaladars, to ensure the funds reach recipients in countries with limited banking access.

HMRC urges businesses offering these services to register for anti-money laundering supervision to protect themselves from criminal exploitation. Registration ensures that businesses implement proper controls to prevent money laundering. Failure to register can result in civil penalties, criminal prosecution, or business closure.

The campaign aims to educate Hawaladars about their legal responsibilities through community radio broadcasts, digital advertising, and local outreach. The initiative follows recent joint visits by HMRC and the National Crime Agency (NCA) to over 40 businesses to help operators understand their obligations.

HMRC’s Deputy Director for Economic Crime said:

“Informal money transfer networks, like Hawala, enable people to support family members in parts of the world where conventional banking is limited. These are vital services that we want to protect from criminal exploitation.

When criminals launder money through these networks, it funds serious organised crime that directly harms the very communities these services support.

By registering with HMRC, businesses can safeguard their services, protect their communities and operate within the law.”
