Companies House ID verification

Major changes are continuing at Companies House as part of the government's efforts to improve corporate transparency and tackle economic crime. One of the most significant developments is the introduction of compulsory identity verification for company directors and Persons with Significant Control (PSCs).

The transition period is now underway, and affected individuals will eventually need to complete verification before they can file information or carry out certain actions on behalf of a company. Although some businesses are already aware of the changes, many smaller companies have not yet reviewed what the new rules may mean in practice.

The identity verification process is intended to confirm that the individuals connected with UK companies are genuine and properly linked to the businesses they control. Verification can either be completed directly with Companies House or through an Authorised Corporate Service Provider, such as an accountant or company formation agent.

The reforms form part of wider changes that are gradually transforming Companies House from a largely passive filing registry into a more active gatekeeper with greater powers to question, challenge and remove information that appears inaccurate or suspicious.

For many smaller businesses, the practical impact may simply involve making sure that director details are correct and ensuring that identity checks are completed before filing deadlines arise. However, businesses that leave preparations until the last minute could face delays and administrative difficulties.

Now may be a good time for company directors to review their Companies House records and consider whether any action is required before the new requirements become fully operational.

Allowable expenses for the self-employed

If you are self-employed, claiming all of your allowable business expenses can significantly reduce your tax bill. For example, if your business turnover is £40,000 and you have £10,000 of allowable expenses, you will only pay tax on your taxable profit of £30,000. However, personal spending and money withdrawn from the business for private use cannot be claimed.

A wide range of business costs may qualify as allowable expenses. These include office expenses such as stationery, phone bills and software subscriptions, as well as the costs of running business premises, including rent, utilities, business rates and insurance. Travel expenses, including fuel, parking charges and public transport costs incurred for business journeys, can also be claimed.

Other common deductible costs include staff wages, subcontractor fees, uniforms and protective clothing, advertising and marketing expenses, website costs, professional subscriptions and certain training courses that help maintain or update existing business skills. Businesses that buy goods for resale can also claim the cost of stock and raw materials.

Those who work from home may be able to claim a proportion of household costs, including heating, electricity, internet charges and rent or mortgage interest. Alternatively, many self-employed individuals can use HMRC's simplified expenses system, which uses flat-rate allowances for working from home, use of vehicles and living at business premises.

Are you affected by the High Income Child Benefit Charge?

Families claiming Child Benefit should be aware of the High Income Child Benefit Charge (HICBC), which can apply when one member of the household has a higher income.

The charge applies where an individual has adjusted net income of more than £60,000 in a tax year and either they or their partner receives a Child Benefit payment. The amount payable increases gradually as income rises, with the charge set at 1% of the Child Benefit received for every £200 of income above £60,000.

As a result, the impact of the charge is phased in rather than applying all at once. However, once income reaches £80,000, the charge effectively claws back all of the Child Benefit received, removing the direct financial benefit of the payments.

Eligible taxpayers can elect to have the charge collected through their PAYE tax code rather than completing a self-assessment tax return. This measure is intended to reduce the administrative burden for employees whose only reason for filing a self-assessment tax return is to declare the HICBC.

Although some families choose to stop receiving Child Benefit to avoid the charge, it is often worthwhile to continue making a claim. Registering for Child Benefit can help protect entitlement to National Insurance credits for parents or carers and ensures children are automatically issued with a National Insurance number shortly before their 16th birthday.

Taxpayers with income approaching or exceeding £60,000 should review their position regularly to ensure they are complying with the rules and making the most appropriate choice for their circumstances.

Pension tax relief and allowances

Pensions remain one of the most tax-efficient ways to save for retirement, due to a range of tax reliefs and allowances that can help boost retirement savings.

One of the key advantages of private pension contributions is the availability of tax relief on pension contributions. Individuals can usually receive tax relief on pension contributions worth up to 100% of their annual earnings subject to an annual allowance. The tax relief effectively reduces the cost of saving into a pension. Basic rate taxpayers benefit from 20% tax relief, while higher rate taxpayers can claim 40% relief and additional rate taxpayers can receive 45% relief on their contributions.

The annual allowance is the maximum amount that can be contributed to pension schemes each tax year before an additional tax charge may arise. The standard annual allowance is currently £60,000 and applies across all of an individual's pension arrangements. In some circumstances it may be possible to contribute more by using the carry forward rules. This allows unused pension allowances from the previous three tax years to be carried forward, provided they made pension contributions during those years.

Pension savers can also benefit from tax-free withdrawals in retirement. Most people can usually take up to 25% of their pension savings as a tax-free lump sum, subject to a maximum lump sum allowance of £268,275. In certain circumstances, including certain death benefits and serious ill-health payments, a higher lump sum and death benefit allowance may apply.

Ensuring that you use all the tax benefits available to you can make a significant difference to the value of retirement savings over the long term.

A reminder to consider the Marriage Allowance

Many married couples and civil partners could be missing out on valuable tax savings available by claiming the Marriage Allowance. If your circumstances are suitable, this is a reminder to consider the Marriage Allowance, as a simple claim could reduce your tax bill by up to £252 during the 2026-27 tax year.

The Marriage Allowance allows a spouse or civil partner with income below their Personal Allowance to transfer £1,260 of that allowance to their partner. The standard Personal Allowance is £12,570 for the 2026-27 tax year. To qualify, the person receiving the transfer must normally be a basic-rate taxpayer and the higher-earning partner must also be a basic rate taxpayer. This generally means they have income between £12,571 and £50,270 during 2026-27. Different limits apply for Scottish taxpayers because of Scotland's separate Income Tax bands.

Although the transfer reduces the lower earner's Personal Allowance, the overall effect is usually beneficial for the couple as a whole. For many households, it provides an easy way to reduce the amount of Income Tax paid without making any changes to their working arrangements or income levels.

It is also worth remembering that claims can be backdated where eligibility existed in earlier years. Eligible couples can currently backdate a claim to 6 April 2022, which could result in a useful lump-sum repayment from HMRC.

Once a successful claim has been made, the allowance will usually continue automatically in future tax years unless it is cancelled or a change in circumstances affects eligibility. Couples whose income levels have changed recently may therefore wish to review whether they qualify and ensure they are not overlooking this tax-saving opportunity.

Who pays Income Tax at Scottish rates?

The rules as to who pays Income Tax in Scotland is determined by whether an individual is considered a Scottish taxpayer or not. For most people, determining Scottish taxpayer status is straightforward. Individuals who live in Scotland are considered Scottish taxpayers, while those who live elsewhere in the UK are not.

If a taxpayer has homes in both Scotland and elsewhere in the UK, HMRC guidance is used to determine their main home for Scottish Income Tax purposes. Those without a permanent home who regularly stay in Scotland, such as offshore workers or hotel residents, may also be liable for SRIT.

If a person moves to or from Scotland during a tax year, their tax liability is determined by where they spent the majority of that year. Scottish taxpayer status applies to the entire tax year and cannot be split.

Those defined as Scottish taxpayers are liable to pay the Scottish Rate of Income Tax (SRIT) on their non-savings and non-dividend income.

What is the Annual Investment Allowance?

The Annual Investment Allowance (AIA) is a valuable tax relief that allows businesses to deduct the full cost of qualifying plant and machinery from their taxable profits. This means that, instead of claiming relief over several years, businesses can often obtain 100% tax relief upfront.

The AIA is currently capped at £1 million per year, and a fresh allowance is available for each accounting period (adjusted if the period is shorter or longer than 12 months).

Most plant and machinery qualifies, including items such as tools, machinery, vans, office equipment, computers and certain building fixtures. However, AIA cannot be claimed on cars, assets previously owned for non-business use or items given to the business.

AIA is available to sole traders, partnerships and companies. However, it is only available to partnerships where all partners are individuals, mixed partnerships that include companies do not qualify.

Timing is important. You can only claim AIA in the period the expenditure is incurred. This is usually the date the contract is signed if payment is due within four months, or the date payment becomes due if later. Special rules apply for hire purchase.

If you do not want to claim the full amount you can claim part of the cost and carry forward the balance using writing down allowances.

Used correctly, AIA can significantly reduce a business’s tax bill, particularly where there is substantial investment in equipment.

Filing your 2025-26 self-assessment tax return

The 2025–26 tax year ended on 5 April 2026, and attention now turns to filing your self-assessment tax return. While many leave this until the last minute, there are advantages to filing early.

There are two ways to file your return. You can submit a paper return, which must be filed by 31 October 2026, or file online, with a deadline of 31 January 2027. The 31 January deadline is also when any tax due for 2025–26 must be paid, along with the first payment on account for 2026–27.

Although the deadline may seem distant, preparing your return early can make a significant difference. Filing early does not accelerate the payment date, but it does give you certainty over how much tax you owe. This allows time to budget and set funds aside, avoiding pressure in January.

There are other benefits too. If you are due a refund, submitting early means you receive it sooner. It also gives more time to gather missing information, resolve queries, and avoid the last-minute rush when systems are busy and deadlines are tight.

In short, early preparation puts you in more control, whether that means planning for a future tax bill or importantly securing a repayment without delay.

When is CGT payable on gains during 2026-27

For most capital gains realised in the 2026–27 tax year, Capital Gains Tax (CGT) is reported and paid by 31 January 2028 via the self-assessment system. This applies to gains on assets such as shares, investments and commercial property.

However, UK residential property is an important exception. Where a residential property is sold and the gain is not fully covered by Private Residence Relief, the capital gain must be reported and paid within 60 days of completion. This rule applies to disposals completed on or after 27 October 2021.

The 60-day deadline mainly applies to rental properties, second homes or properties only partly used as a main residence. If the property is jointly owned, each owner must report and pay tax on their share of the gain separately.

To calculate the gain, you will need details such as purchase and sale dates, acquisition cost, legal and professional fees, and qualifying improvement expenditure. Selling costs, including estate agent and legal fees, can also be deducted. Gathering this information in a timely manner is important given the tight 60-day deadline.

If you have disposed of, or are planning to dispose of, an asset that may give rise to a gain, we would be happy to help you calculate taxable gains, ensure that the filing and payment deadlines are met and avoid unnecessary interest or penalties.
