Paper tax returns are due 31 October 2025, and new registrants must notify HMRC by 5 October 2025. Act early to avoid penalties.

Firstly, the deadline for submitting paper self-assessment tax returns is 31 October 2025. If you miss this deadline a £100 late filing penalty will usually apply, even if no tax is due, or if any tax owed is paid in full by the final deadline of 31 January 2026.

Further penalties increase the longer the return remains outstanding. If your return is still not filed three months after the deadline, daily penalties of £10 per day (up to a maximum of £900) will be charged. If the delay extends to six months or more, further fixed or percentage-based penalties may apply, significantly increasing the cost of non-compliance.

We strongly recommend that anyone still submitting paper returns consider switching to the online filing system. Filing electronically not only simplifies the process but also gives you an extra three months, with the deadline for online returns falling on 31 January 2026.

The second key deadline is 5 October 2025. This is the date by which you must notify HMRC if you need to complete a self-assessment return for the 2024–25 tax year and have not previously been required to file one. Failing to register in time can lead to penalties for late notification, even if you file your return on time later.

Being aware of these October deadlines and taking timely action can help you avoid unnecessary stress and potential fines if you were unprepared.

Not all casual payments are tax-free; HMRC’s miscellaneous income rules may apply depending on the circumstances.

The special miscellaneous income rules sweep-up provisions that seek to charge tax on certain income. This unusual provision, which is broad in scope, catches income that would not otherwise be charged under specific provisions to Income Tax or Corporation Tax.

A casual payment may be considered taxable miscellaneous income when it is received as a reward for a service that was performed under some form of agreement, arrangement, or common understanding that payment would be made.

This is different from a genuine gift or token of appreciation given voluntarily after a service, where there was no agreement, arrangement or common expectation for such a reward. These gifts are not taxable under the same provisions.

The distinction can be difficult to define. For example, in Brocklesby v Merricks (1934), the court highlighted the importance of an arrangement or entitlement to a share of earnings to make a receipt taxable. As a result, it is essential to review the specific circumstances of each case to determine whether a payment qualifies as taxable income or a non-taxable gift.

Businesses over £90,000 turnover must register for VAT, but HMRC may grant exceptions if the increase is temporary.

A business must register for VAT if either of the following applies:

1. At the end of any month, its taxable turnover in the previous 12 months has exceeded £90,000; or
2. At any point, it is reasonable to expect that taxable turnover in the next 30 days alone will exceed £90,000.

If a business temporarily exceeds the VAT registration threshold, they may be able to apply for an exception from VAT registration with HMRC. This applies if their taxable turnover has gone over the threshold in the last 12 months, but the business can show it will not go over the deregistration threshold (£88,000) in the next 12 months. This exception must be applied for by contacting HMRC to request and complete forms VAT1 and VAT5EXC. It’s important to note that this is different from a full VAT exemption.

Once an application is submitted, HMRC will respond within 40 working days to confirm approval or refusal. If approved, the business will not be registered for VAT at that time but will remain required to monitor their turnover monthly in case their circumstances change, and VAT registration is required. If the exception is denied, HMRC will register a business based on the information provided, and the business will be required to account for VAT from the date their liability began.

When considering VAT on entertainment provided solely to directors or partners of a business it is generally not recoverable as VAT Input Tax.

HMRC considers that directors and partners are not in need of entertainment to motivate themselves, so such costs are not for business purposes. However, exceptions apply for subsistence costs (e.g., meals or accommodation during business travel), and no apportionment is needed when directors or partners attend general staff events.

In contrast, VAT incurred on entertainment for employees, such as staff parties, team-building events, or outings, is usually considered by HMRC as a business expense and can be fully recovered.

In cases of mixed entertainment, where both employees and non-employees (e.g., guests) are present, the VAT must be apportioned. Only the portion relating to employees is recoverable. VAT on entertainment for non-employees is generally blocked, unless the guest is an overseas customer, in which case input tax is not blocked, but output tax may apply.

For many business owners, a vehicle is an essential tool. Whether it is for visiting clients, delivering goods, or simply keeping things moving, choosing how to finance a vehicle can have a big impact on cash flow and tax planning. There are several routes to consider, each with its own advantages.

Buying outright

The simplest option is to purchase the vehicle in full. This means your business owns it from day one. Buying outright avoids ongoing finance costs, but it does tie up capital. The tax advantage is that you may be able to claim capital allowances on the cost, reducing taxable profits. Cars with low CO₂ emissions attract more generous allowances, while commercial vehicles such as vans can often qualify for the full Annual Investment Allowance.

Hire purchase

Hire purchase spreads the cost of the vehicle over a fixed term. You make monthly instalments and become the legal owner once the final payment is made. Interest will be payable, but this option gives certainty over repayments and allows you to claim capital allowances on the vehicle as if you had bought it outright.

Finance lease

With a finance lease, your business pays to use the vehicle but never actually owns it. Instead, you may be able to extend the lease at a reduced cost or sell the vehicle on behalf of the finance company and keep part of the sale proceeds. The rentals are tax deductible, which helps to reduce taxable profits.

Contract hire

Contract hire is often called leasing. You agree to use the vehicle for a set period and mileage, paying fixed monthly rentals. At the end of the agreement, the vehicle is returned. This option keeps vehicles off your balance sheet and helps with budgeting, as servicing and maintenance can be included. The rentals are usually deductible for Corporation Tax, but restrictions apply if the car has high emissions.

Personal contract purchase (PCP)

Some directors use PCP agreements through the company. These combine monthly payments with the option to buy the vehicle at the end for a lump sum. The tax treatment is similar to hire purchase if the business owns the agreement, but careful thought is needed if it is held personally.

Final thought

There is no one best option. The right choice depends on cash flow, tax position, and how long you intend to keep the vehicle. Speaking with your accountant before committing can ensure the vehicle is financed in the most efficient way for your business.
