Welcome to Your July 2025 Newsletter

As we head into the second half of the year, change is in the air- both regulatory and financial. This month, we’re focusing on some key updates that may affect you or your business in the coming months. From identity checks soon to be required by Companies House, to the importance of registering a payroll scheme correctly, we cover practical steps to keep you compliant and informed.

We also explore the growing significance of tax planning for high net worth individuals, clarify how small streams of additional income may impact your tax obligations, and highlight HMRC’s latest data on the UK tax gap. Plus, there’s some good news for pensioners as Winter Fuel Payments are reinstated for 2025-26.

As always, we’ve included the latest tax diary dates to help you stay ahead of deadlines. If any of these topics raise questions or spark concerns, we’re here to help you navigate the details.

Are you ready for Companies House ID checks?

From 2025, Companies House is rolling out new identity verification requirements for directors, people with significant control (PSCs), and anyone forming or managing a UK company. These changes form part of the Economic Crime and Corporate Transparency Act and are designed to reduce fraud and increase confidence in UK companies.

If you are involved in running a business, you may soon need to prove your identity either directly through Companies House or via a registered agent such as your accountant. Without completing verification, you will not be allowed to register a company or take up a new role as a director or PSC.

These rules apply to:

• Company directors (existing and new)
• Individuals with significant control (usually shareholders with 25% or more of shares or voting rights)
• Company formation agents
• Anyone filing information at Companies House on behalf of a business

The new system is already partially in place. Since April 2025, authorised agents can verify identities on behalf of their clients, but from a future date still to be announced, Companies House will require all key company officers to comply before filings will be accepted.

For business owners, this means a few practical actions:

• Ensure all directors and PSCs have current and valid photo ID.
• Decide whether you want to complete ID checks directly or use an authorised agent.
• Check that your company’s records at Companies House are up to date.

We expect enforcement and deadlines to follow later in the year, so it is wise to prepare in advance. If you are uncertain how these changes affect you, or how best to carry out the verification, we are happy to help.

Do you have additional income streams?

Side income over £1,000 may mean filing a tax return. HMRC is urging part-time earners to check their tax position for 2024-25, especially if they earn from casual work, renting, or crypto.

If you are earning extra income it is important to be aware of the tax implications.

The good news is there are two £1,000 tax allowances available for small amounts of miscellaneous income. The first is for property income and the second is for trading income. If you have both types of income, you can claim £1,000 for each.

• Trading Allowance: If you make up to £1,000 from self-employment, casual services (like babysitting or gardening), or renting out personal equipment (such as power tools), this income is tax-free and doesn’t need to be declared.
• Property Allowance: If you earn £1,000 or less from property-related activities (like renting out a driveway), you don’t need to report it to HMRC or include it in your tax return.

These allowances cover all relevant income before expenses. If your income is under £1,000, it’s tax-free. If you earn more than £1,000, you can choose to either deduct the £1,000 allowance from your income or list your actual expenses when calculating your taxable profit.

However, if your part-time income exceeds £1,000 in a tax year, you may need to complete a self-assessment tax return. This includes gains or income received from cryptoassets. Keep in mind this only applies if you are actively trading or selling services. If you are just clearing out personal possessions by selling them, there is usually no need to worry about tax.

If you are required to submit a tax return for the 2024-25 tax year, then the deadline to submit a tax return online and pay any tax owed is 31 January 2026.

Setting up a payroll scheme

Registering for payroll is essential when hiring staff. From HMRC registration to legal compliance, getting payroll processes right ensures your team is paid correctly and your business avoids penalties.

When starting a business and hiring employees for the first time, one of the most important administrative steps is setting up a payroll scheme. This process ensures your employees are paid correctly and that your business complies with the necessary tax and employment laws.

The first step is to register as an employer with HMRC. You must register even if you are only employing yourself, for example you are the director of a limited company. This registration must be completed before your first payday. You need to register in most scenarios including for any employee earning at or over the minimum secondary threshold of £96 a week (2025-26 threshold).

Another important part of the payroll process is deciding whether you will run payroll yourself or use a payroll provider. If you manage it yourself, you must choose an approved HMRC-recognised payroll software to record employee details, calculate pay and deductions and report to HMRC.

Once registered, you’ll need to:

• Collect and maintain employee records.
• Report employee information to HMRC.
• Make accurate tax and National Insurance deductions.
• Submit reports to HMRC using Real Time Information (RTI) on or before each payday.
• Pay HMRC what you owe in tax and National Insurance.

You must also:

• Comply with National Minimum Wage laws.
• Check employees’ legal right to work in the UK.
• Set up a workplace pension scheme for eligible staff.

You will also need to complete annual payroll tasks. Setting up a payroll scheme can be complex, and we would of course be happy to help you choose the optimal set-up for your circumstances. We can also, if required, manage the payroll process for you.

Tax gap estimated at 5.3% for 2023-24

HMRC missed out on £46.8bn in tax last year. Small businesses and Corporation Tax make up the biggest share of the shortfall.

The tax gap for the 2023-24 tax year has been published and is estimated to be 5.3% of total theoretical tax liabilities.

The tax gap is basically the difference between the amount of tax that should have been paid to HMRC and the amount of tax collected by the Exchequer. The gap includes tax that has been avoided in the UK’s black economy, by criminal activities, through tax avoidance and evasion. However, it also includes simple errors made by taxpayers in calculating the tax they owe as well as outstanding tax due from businesses that have become insolvent. 

In monetary terms, the tax gap is equivalent to lost tax of £46.8 billion. This means that HMRC collected £829.2 billion or 94.7% of all tax due.

The government has announced plans to raise a further £7.5 billion through its measures to close the tax gap.

Some of the key findings from this year’s calculations show:

• Small businesses represent the largest proportion of the tax gap (60%).
• Corporation Tax accounts for 40% of the total tax gap.
• Failure to take reasonable care (31%), error (15%) and evasion (14%) are among the main behavioural reasons for the overall tax gap.

As announced at Spending Review 2025, £1.7 billion will be provided to HMRC over four years to fund an additional 5,500 compliance and 2,400 debt management staff in order to try and ensure that more of the tax due is paid, to fund public services. 

Winter Fuel Payments reinstated

The government has announced the reinstatement of Winter Fuel Payments for pensioners in England and Wales for winter 2025-26, reversing the previous year’s cuts. Around nine million pensioners are expected to benefit from this decision, with payments of £200 per household or £300 for households where someone is aged 80 or over.

Eligibility will be based on age and income. Anyone who has reached State Pension age by the qualifying week of 15 to 21 September 2025 and earns £35,000 or less will receive the payment automatically. Pensioners with higher incomes will still receive the payment but may have it recovered through the PAYE or Self-Assessment systems. Alternatively, they can opt out of receiving the support altogether.

The move is part of a broader attempt to provide targeted help to those most in need while managing public finances responsibly. The scheme is expected to cost around £1.25 billion, but by introducing means-testing for higher earners, the government aims to save approximately £450 million compared to the previously universal scheme.

The decision follows public concern about last year’s removal of the payment, which had a significant impact on many lower-income pensioners. It has been welcomed by pensioners’ groups and campaigners who argued that older people should not be left without support during the winter months.

Full details of how to apply or opt out, along with confirmation of eligibility, will be published later in the summer, with funding arrangements to be finalised in the Autumn Budget.

The value of tax planning for high net worth individuals

For high net worth individuals (HNWIs), tax planning is not simply a compliance activity, it is a strategic tool to preserve and grow wealth. With rising scrutiny from HMRC, frozen allowances, and increasingly complex legislation, the value of well-structured planning has never been higher.

HNWIs typically have multiple sources of income: from employment, dividends, property, pensions, or overseas investments. This complexity brings opportunities, but also risk. Without active tax planning, much of that income can be lost to inefficient structuring or missed reliefs.

Using allowances such as the personal allowance, dividend allowance, and savings allowance is key. Where income exceeds £100,000, tapering of allowances becomes relevant. Income splitting between spouses and the use of family investment companies or trusts can help manage liabilities.

The capital gains tax (CGT) annual exemption is now only £3,000 (2025-26). Disposals must be timed carefully, with use of spousal exemptions or crystallising gains across tax years considered.

HNWIs are most exposed to inheritance tax (IHT), which charges 40% on estates above £325,000 (plus any residence nil-rate band). Making lifetime gifts, using trusts, and taking advantage of the exemption for gifts from surplus income can significantly reduce exposure.

Global families must manage UK tax residency and domicile status carefully. The remittance basis may apply to foreign income, but this often requires payment of the remittance basis charge. Changes to domicile treatment post-April 2025 make planning in this area even more important.

Pensions, ISAs, and offshore bonds can provide valuable tax sheltering. For HNWIs, using the annual and lifetime pension allowances efficiently, especially while they remain available, is a core planning task.

In summary, proactive tax planning is about more than saving money. It gives HNWIs confidence, control, and the ability to plan for the future. With HMRC increasing its focus on high earners, reviewing tax affairs annually is no longer optional, it makes good financial sense.
