The Insolvency Service data for England and Wales shows monthly company insolvencies remain high by historical standards, even though they move up and down month to month. For example, November 2025 recorded 1,866 registered company insolvencies, down on October 2025 and also below the same month a year earlier. The wider context matters, monthly totals through 2025 have generally been slightly higher than 2024, but lower than 2023, which saw a 30 year high in annual insolvencies.

New company formations: still strong, but down on the prior year

On the formations side, Companies House figures show incorporation volumes have softened. In the financial year ending 2025, there were 801,864 company incorporations, down 10% compared with the financial year ending 2024. At the same time, dissolutions rose, with 726,735 dissolutions in the financial year ending 2025, up 9.6% on the prior year.

Quarterly data shows how this can translate into net shrinkage in the register for periods of time. Between July and September 2025 there were 215,982 incorporations and 234,373 dissolutions, so dissolutions outpaced incorporations in that quarter.

A practical way to read this is that the “start-up engine” is still running, but not as hot as it was, while the “clean-up” of non-viable businesses has accelerated.

Why both trends can be true at the same time

ONS business demography data helps explain the apparent contradiction. On an enterprise basis (different from Companies House incorporations, but directionally helpful), business births edged up from 316,000 to 317,000 between 2023 and 2024, while business deaths fell from 310,000 to 280,000, producing the lowest death rate since 2016.

So, depending on which lens you use, you can see: (a) high company insolvency activity, (b) lower incorporations than the prior year and (c) relatively resilient enterprise births and improved enterprise death rates. Differences in definitions and timing matter, but the shared message is that the UK is in a reallocation phase: weaker balance sheets and marginal business models are being pushed out, while new ventures keep forming, often leaner, more specialised and sometimes set up to replace old entities.

Pre-tax year end planning is one of the most practical and controllable ways for UK businesses and higher rate taxpayers to reduce unnecessary tax exposure. Unlike long term restructuring, it focuses on decisions that can still be influenced before 5 April or, for companies, before the accounting year end. When done properly, it is not about aggressive schemes, it is about making sure allowances, reliefs and timing opportunities are not wasted.

Why timing matters

The UK tax system is sensitive to timing. Income, expenses, capital purchases and pension contributions can fall into one tax year or the next depending on when action is taken. Once the year end passes, many opportunities disappear completely.

For higher rate taxpayers, this can be particularly costly. Income drifting just over a threshold can trigger higher marginal rates, loss of allowances or reduced reliefs. Pre-year end planning allows income levels to be reviewed and steps taken to mitigate sharp jumps in tax, rather than reacting after the event.

Key benefits for businesses

For owner managed businesses, year-end planning often centres on profit extraction and investment decisions. Reviewing results before the year end allows directors to consider whether profits should be retained, extracted as salary or dividends or redirected into qualifying expenditure.

Capital allowances are a common example. If a business plans to invest in plant or equipment, bringing expenditure forward into the current year can accelerate tax relief and improve cash flow. Pension contributions made by the company can also be an efficient way to extract value, reducing corporation tax while building long term personal wealth.

Stock levels, bad debts and provisions also deserve attention. A timely review can ensure profits are not overstated simply because adjustments were overlooked.

Value for higher rate and additional rate taxpayers

Individuals paying tax at higher or additional rates face some of the steepest marginal tax charges in the system. Pre-tax year end planning can help smooth income and preserve reliefs.

Pension contributions are often central. Personal contributions can attract higher rate relief, while also reducing adjusted net income, which can help protect allowances that taper away at higher income levels. Charitable giving under Gift Aid can have a similar effect.

For those with investment income, reviewing disposals before the year end can allow better use of annual exemptions or losses, rather than triggering avoidable capital gains tax.

The new 40% First Year Allowance (FYA) for qualifying main-rate plant and machinery expenditure first announced at Autumn Budget 2025 has now come into force.

Effective from 1 January 2026, the new FYA applies to qualifying main-rate plant and machinery expenditure. It was also announced at the recent Autumn Budget 2025 that the main rate writing down allowances would be reduced to 14% (from 18%) from 1 April 2026 for Corporation Tax purposes and from 6 April 2026 for Income Tax purposes.

These changes mean that:

• Businesses can claim a 40% FYA on qualifying main-rate plant and machinery.
• The allowance applies to assets acquired for leasing, which did not qualify from full expensing.
• Unincorporated businesses, including sole traders and partnerships can also benefit from the FYA. These businesses did not benefit from full expensing.
• The allowance is permanent, providing long-term certainty for investment and capital planning.

The new FYA complements the existing full expensing regime, which remains in place for incorporated businesses. Full expensing allows companies to deduct 100% of the cost of qualifying plant and machinery from taxable profits in the year of acquisition, delivering tax savings of up to 25p for every £1 invested, in line with the current Corporation Tax rate.

Understanding how the new 40% FYA interacts with existing allowances, including full expensing and annual investment allowances, will be important when considering expenditure going forward.

The government recently announced significant changes to the planned reforms to Agricultural Property Relief (APR) and Business Property Relief (BPR). The threshold for 100% relief will be increased from £1 million to £2.5 million when the changes take effect from 6 April 2026. The change will be introduced via an amendment to the Finance Bill 2025 with relief reduced to 50% on qualifying assets above the new level.

Spouses or civil partners will be able to pass on up to £5 million of qualifying agricultural and business assets between them free of inheritance tax, in addition to the existing nil rate bands. The transferable allowance will also apply to surviving spouses or civil partners who were widowed before the new policy was announced.

These changes adjust the reforms first announced at Autumn Budget 2024, which had attracted strong criticism from the farming community and rural businesses over the potential impact on small farms and family-owned enterprises. By raising the threshold, the government aims to significantly reduce the number of estates affected by higher inheritance tax charges, ensuring that the reforms are focused primarily on the largest estates.

The government estimates that around 85% of estates claiming APR in 2026–27, including those also claiming BPR, will pay no additional inheritance tax as a result of these changes.

Shares designated as “not listed”, such as those traded on AIM, will attract BPR at a flat rate of 50% (reduced from 100%) from April 2026. This measure was unaffected by the latest announcement.

HMRC’s figures show thousands of taxpayers are filing over the festive period, but leaving your return until late January risks penalties, stress and avoidable payment problems.

A new press release by HMRC has highlighted that 4,606 taxpayers took the time to file their tax return online on Christmas Day with a further 10,479 taxpayers completing their tax returns on Boxing Day. In total, 37,435 self-assessment returns were filed between 24 and 26 December and a further 54,053 returns between New Year’s Eve and New Year’s Day. HMRC even joked that festive filing has, for some, become as much a Christmas tradition as watching the King’s Speech or avoiding the washing up!

HMRC’s Chief Customer Officer, said:

‘Millions of customers have already completed their tax returns and can start 2026 with one less thing to worry about. For anyone yet to file, don’t leave it until the last minute. Filing now means you know exactly what you owe and have time to arrange payment. Search ‘Self-Assessment’ on GOV.UK to get started.’

If you are filing online for the first time you should ensure that you register to use HMRC’s self-assessment online service as soon as possible. Once registered an activation code will be sent by mail. This process can take up to 10 working days. 

We would encourage our readers to complete their tax return as early as possible to avoid the last-minute stress as the 31 January 2026 filing date looms. If you miss the filing deadline then you will be charged a £100 fixed penalty (unless you have a reasonable excuse) which applies even if there is no tax to pay, or if the tax due is paid on time. There are further penalties for late tax returns still outstanding 3 months, 6 months and 12 months after the deadline. There are also additional penalties for paying late of 5% of the tax unpaid at 30 days, 6 months and 12 months.
