If one partner in a marriage or civil partnership earns under £12,570, you could save up to £252 a year, and up to £1,260 if you backdate your Marriage Allowance claim for the past four years.

The Marriage Allowance can be claimed by married couples and civil partners where one partner does not pay tax or does not pay tax above the basic rate threshold for Income Tax (i.e., one partner must earn less than the £12,570 personal allowance for 2025-26).

If claimed, the lower-earning partner can transfer up to £1,260 of their unused personal tax-free allowance to their spouse or civil partner. The transfer can only be made if the recipient (the higher-earning partner) is taxed at the basic 20% rate, which typically means they have an income between £12,571 and £50,270. For those living in Scotland, this would usually apply to an income between £12,571 and £43,662.

By using the allowance, the lower-earning partner can transfer up to £1,260 of their unused personal allowance, which could result in an annual tax saving of up to £252 for the recipient (20% of £1,260).

If you meet the eligibility criteria and have not yet claimed the allowance, you can backdate your claim for up to four years. This could provide a total tax saving of up to £1,260 and would include the tax years 2021-22, 2022-23, 2023-24, 2024-25 and the current 2025-26 tax year. Applications for the allowance can be submitted online at GOV.UK.

Lifetime gifts can reduce Inheritance Tax, but survival for seven years and using key exemptions like the £3,000 annual allowance are crucial to making them fully tax-free.

Most gifts made during a person’s lifetime are not immediately subject to Inheritance Tax (IHT). These are known as potentially exempt transfers (PETs) and can become completely exempt from IHT if the person making the gift (the donor) survives for more than seven years after making the gift.

If the donor dies within three years of making the gift, it is treated as if the gift was made on the date of death, and the full rate of IHT may apply. However, if death occurs between three and seven years after the gift, taper relief can reduce the amount of tax payable. The further away from death the gift was made, the lower the tax rate applied, although this only reduces the tax due on the amount above the nil rate band.

It’s important to note that taper relief does not reduce the value of the gift itself, only the tax payable, and it does not apply where the gift is within the nil rate band. Additionally, it does not lower the tax on chargeable lifetime transfers to below the amount originally assessed when the gift was made.

Each tax year, individuals can also take advantage of specific IHT exemptions that allow gifts to be made tax-free, regardless of survival for seven years.

The annual exemption allows you to gift up to £3,000 in total each tax year without adding to the value of your estate for IHT purposes. This amount can be given to one person or shared among multiple recipients. If the full £3,000 exemption isn’t used in one tax year, it can be carried forward, but only for one additional tax year.

The small gift allowance allows you to give as many gifts of up to £250 per person per tax year as you like, as long as no other exemption is used for the same individual. This is ideal for birthday or seasonal gifts made from regular income.

Additionally, you can make tax-free gifts in celebration of weddings or civil partnerships. These are exempt up to £5,000 for a child, £2,500 for a grandchild or great-grandchild and £1,000 for anyone else.

The BADR Capital Gains Tax rate has risen to 14% from April 2025 and will increase further to 18% in April 2026.

Business Asset Disposal Relief (BADR) offers a valuable tax advantage by applying a reduced rate of Capital Gains Tax (CGT) on the sale of a business, shares in a trading company or an individual’s interest in a trading partnership.

As part of the measures announced in the Autumn 2024 Budget, the CGT rate for gains eligible for BADR has increased. For disposals made on or after 6 April 2025, the CGT rate has risen from the previous 10% to a higher rate of 14%. This change is now in effect and applies to any qualifying disposals taking place within the 2025–26 tax year.

Another forthcoming increase to the CGT rate under BADR is set to take place from 6 April 2026. It will rise to 18%. This means that disposals qualifying for BADR on or after this date will face a significantly higher tax charge compared to the original 10% rate that had long been associated with the relief.

The lifetime limit for claiming BADR remains at £1 million. This means that individuals can still benefit from the relief more than once, provided the cumulative gains across all qualifying disposals do not exceed this threshold.

Changes have also been made to Investors’ Relief. Specifically, the lifetime limit for Investors’ Relief was reduced from £10 million to £1 million for qualifying disposals made on or after 30 October 2024. In addition, the CGT rates for Investors’ Relief have now been brought in line with those of BADR currently at 14% and increasing to 18% from April 2026.

Identity verification is now rolling out for directors, PSCs, and agents, with more filing roles to be included soon under new anti-fraud rules.

Companies House is beginning to roll out mandatory identity verification. This is part of wider reforms introduced by the Economic Crime and Corporate Transparency Act that was granted Royal Assent in October 2023. This legislation strengthens Companies House’s authority to prevent the misuse of corporate structures and tackle economic crime.

A key feature of the Act is the requirement for identity checks for individuals involved in company formation, management, or ownership in the UK. Eventually, anyone incorporating a company or being appointed as a director or a person with significant control (PSC) will be legally required to complete identity verification.

Authorised Corporate Service Providers (ACSPs)

Since 18 March 2025, any ACSP that is defined as an individual or organisation conducting Anti-Money Laundering (AML) supervised activities must verify their identity before they can register as an authorised agent with Companies House.

Since 8 April 2025, ACSPs that are registered as authorised agents are permitted to carry out identity verification on behalf of their clients. This means that only those registered as authorised agents will be allowed to submit filings on behalf of other businesses.

Directors and Persons with Significant Control (PSCs)

Also, since 8 April 2025, directors and PSCs are able to verify their identity voluntarily. Over time, this step will move from optional to mandatory, forming a required part of compliance when forming or managing a company.

Individuals Filing with Companies House

At present, identity verification is not compulsory for individuals submitting filings to Companies House. However, this will also change in due course, with verification becoming a statutory obligation in the future.

The Court of Appeal addressed the complexities of benefit scheme amendments and the lines of responsibility within corporate structures in a complex case surrounding post-employment entitlements. A Mr. Fasano had been an employee of RB Health Ltd., a member of the Reckitt Benckiser (RB) Group of companies, until the 13th of June 2019. The RB Group operates a long-term incentive plan, or LTIP, which makes provision of shares or share options for senior personnel employed by its various companies. 

On the 18th of September 2019, RB Group amended the terms of the 2015 LTIP, requiring those participating in the 2015 LTIP to be employed as of 18 September 2019 to benefit from amended performance conditions in May 2020. Thus, Mr. Fasano was not eligible for an award under the amended LTIP rules. Mr. Fasano brought his case against RB Health and the RB Group to a tribunal, alleging that he had been subjected to indirect discrimination on the grounds of age, contrary to Sections 19 and 39 of the Equality Act 2010. 

However, the tribunal held that RB Group was acting as the agent of RB Health when it amended the terms of the rules of the 2015 LTIP and that the provision, criterion or practice (PCP) thus pursued a legitimate aim. On appeal, it was found that the PCP applied by RB Group was incapable of achieving any legitimate aim of retaining staff and thus was not justified. However, the appeal was ultimately dismissed as the RB Group was not acting as the agent of RB Health, and neither RB Health nor RB Group was liable by reason of Sections 109 and 110 of the Act. 

The Court of Appeal dismissed the appeal and agreed with the appeals tribunal that RB Group was not acting as an agent for RB Health when it amended the performance conditions of the LTIP. Therefore, RB Health is not, therefore, liable for any change made by RB Group to the LTIP pursuant to Section 109 of the Act. The Judge emphasised that, for agency to exist under common law and therefore within the scope of the Act, there needs to be clear authorisation from the principal (RB Health) for the agent (RB Group) to act on its behalf as regards a third party, such as Mr. Fasano. The fact that RB Health's employees benefited from the LTIP didn't automatically make RB Group its agent, although there might have been a different outcome if the rules had been applied by an employer to current employees.  

This case demonstrates that, if a parent company, rather than the direct employer, makes a discriminatory decision regarding benefits, it might be harder to hold the direct employer liable under agency principles. Nonetheless, employers need to ensure that any performance-related policies are justifiable in their aim and implementation and non-discriminatory. 

Gross profit margin
This measures the profitability of your core operations by comparing gross profit (sales minus cost of goods sold) to total revenue. A stable or improving gross margin indicates pricing, production, or service delivery is efficient. A declining margin may signal rising costs or pricing issues.

Formula: (Gross Profit ÷ Revenue) × 100

Cash flow
Positive cash flow ensures a business can meet its obligations, pay suppliers and staff, and invest in growth. Even profitable businesses fail without adequate cash. Tracking cash flow (operating, investing, and financing activities) helps prevent liquidity crises.

Monitor: Monthly net cash inflow/outflow and rolling 3-month cash forecast

Customer acquisition cost (CAC)
This shows how much it costs to acquire a new customer. If CAC is rising without a corresponding increase in customer value or retention, it can drain profitability. Ideally, CAC should be lower than the revenue generated by each customer over their lifetime.

Formula: Total Sales and Marketing Costs ÷ Number of New Customers

Net profit margin
This is the bottom line—what remains after all costs, taxes, and interest. It reflects overall efficiency and financial viability. A strong net margin gives room for reinvestment and debt servicing, and signals long-term sustainability.

Formula: (Net Profit ÷ Revenue) × 100

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.

Buying a zero-emission electric car through your limited company could mean 100% tax relief in year one. Understand the capital allowances and boost your business’s tax efficiency with smart vehicle choices.

If you are considering purchasing a company car through a limited company, it’s important to understand the tax implications, especially the significant tax write-offs available for electric vehicles with zero emissions.

The tax treatment will depend on how the car is financed, but in most cases, the vehicle will be classified as a fixed asset, with tax relief available through capital allowances. Unlike other business assets, company cars do not qualify for the Annual Investment Allowance (AIA). Instead, they fall into specific capital allowance categories based on their CO₂ emissions and when they were purchased.

If you purchase a new and unused fully electric or zero-emission car, it qualifies for a 100% First Year Allowance (FYA). This means:

If the car does not meet the criteria for 100% FYA, it will fall into one of the following categories:

Expecting lower profits 2024-25 compared to 2023-24? You can ask HMRC to reduce your 31 July 25 tax payment on account. Act early to manage cash flow. Use your online account or we can handle it for you.

Self-assessment taxpayers normally pay their income tax in three instalments each year. The first two payments on account are due on 31 January during the tax year and 31 July after the tax year ends. These are each based on 50% of the previous year’s net income tax liability.

This means that the 31 January 2025 (now passed) and upcoming 31 July 2025 payments are both based on your 2023–24 tax liability.

A final balancing payment is due on 31 January 2026, once your actual tax bill for 2024–25 has been confirmed through your submitted tax return.

If you expect your income or profits for 2024–25 to be lower than for 2023–24, you can ask HMRC to reduce your 31 July 2025 payment on account. This can be done through your HMRC online account or by submitting form SA303 by post. You must provide a reasonable estimate of your expected tax liability.

If we are your registered tax agent we can undertake this election for you.

There is no limit to how many times you can apply to adjust your payments. However, if you reduce your payments too far and underpay, HMRC may charge interest or penalties on the shortfall.

You are not required to make payments on account if:

If your taxable profits are likely to increase in 2024–25, there’s no need to notify HMRC in advance, but you should be prepared for a higher balancing payment in January 2026.
