Starting a new business can be expensive, but many of your pre-trading costs may qualify for tax relief if they meet the right conditions.

There are special tax reliefs for pre-trading expenses that are incurred before a business starts trading. This could include expenses that are required to help a business prepare for trading such as buying stock and equipment, renting premises, getting insurance and initial advertising expenditure. 

A deduction may be allowed where the following conditions are met: 

• The expenditure is incurred within a period of seven years before the date the trade, profession or vocation commenced, and
• the expenditure is not otherwise allowable as a deduction in computing the profits of the trade, profession or vocation but would have been so allowable if incurred after the trade had commenced.

To be allowable, the pre-trading expenditure must be incurred wholly and exclusively for the purposes of the relief. To be clear, this means that no relief would be allowed where pre-trading expenses would not have been tax deductible if they had been incurred when the business was trading. The business should keep accurate records relating to pre-trading expenditure to be able to demonstrate that the expenses are qualifying.

The qualifying pre-trading expenditure is treated as incurred on the day on which the trade, profession or vocation is first carried on. 

Capital expenditure does not qualify for this relief but there are other special provisions for capital allowances. 

Did you know you can monitor any UK company for free and get email alerts when key details change, which can help protect your own business from unexpected or unauthorised filings?

A significant amount of information about companies is available in the public domain from Companies House. Companies House is responsible for incorporating and dissolving limited companies, examining and maintaining statutory records, and making company information publicly accessible.

Much of this information is available free of charge, in line with the government’s commitment to open data. As a result, all publicly available digital information held on the UK register of companies can be accessed without cost.

The information available includes core company details such as the registered address and date of incorporation, details of current and resigned directors and officers, copies of documents filed with Companies House, mortgage and charge information, previous company names and insolvency records.

In addition, you can choose to monitor a company and receive email alerts whenever new documents are filed, such as changes to directors or registered office addresses. This can also be a useful safeguard for your own company, helping you to identify any unexpected or unauthorised filings at an early stage.

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.
