Practical year-end tax planning for UK businesses

Year-end tax planning is not about making rushed decisions in the final few weeks of an accounting period. It is about reviewing where the business stands, understanding the tax position, and making sensible choices before the opportunity passes.

For UK limited companies, the timing of expenditure, investment, profit extraction and relief claims can all affect the final Corporation Tax position. The right approach will depend on the company’s profits, cash flow, shareholders, directors and plans for the next year.

This is especially important because UK Corporation Tax is not a single-rate issue for every company. The main Corporation Tax rate is 25%, while companies with profits of £50,000 or less may pay the 19% small profits rate. Marginal relief can apply where profits fall between £50,000 and £250,000, although these thresholds can be affected by associated companies.

Here are five practical tax planning areas every UK business should consider before year-end.

1. Review planned capital expenditure

If your business is planning to buy equipment, machinery, vans, computers, tools or other qualifying business assets, the timing of the purchase may matter.

Capital allowances allow a business to deduct some or all of the cost of qualifying plant and machinery from taxable profits. HMRC lists the Annual Investment Allowance, 100% first-year allowances and other capital allowance routes as possible forms of relief, depending on the asset and the business circumstances.

For many businesses, the key question is whether expenditure should be brought forward before the year-end, especially where the asset is genuinely needed and the purchase is already planned.

This might include:

• laptops, servers or office equipment
• tools or machinery
• commercial vehicles
• fixtures or equipment for business premises
• specialist operational equipment

The Annual Investment Allowance can allow businesses to deduct the full value of qualifying plant and machinery from profits, up to the AIA limit. HMRC states that AIA can be claimed on most plant and machinery up to the AIA amount.

Companies may also need to consider whether full expensing or the 50% first-year allowance applies. HMRC confirms that only companies can claim full expensing and the 50% first-year allowance, and that these apply to certain plant and machinery bought from 1 April 2023, provided the asset is new and unused and is not a car.

However, tax relief should not become a reason to spend money unnecessarily. A deduction rarely makes a poor commercial purchase worthwhile. The first test should always be whether the business actually needs the asset.

The second test is timing. If the business is already planning to buy something shortly after year-end, it may be worth considering whether completing the purchase before the year-end would accelerate tax relief.

2. Check whether all allowable expenses have been captured

Many businesses underclaim expenses simply because records are incomplete.

Before year-end, it is worth reviewing whether all costs have been properly recorded, especially where directors, employees or owners have paid for items personally.

Common areas to check include:

• software subscriptions
• professional fees
• training costs
• business mileage
• use of home as office
• mobile phone and internet costs
• staff expenses
• bank charges and finance costs
• small tools, equipment and office supplies
• unpaid supplier invoices relating to the period

This is also a useful time to review prepayments and accrued costs. Some expenses may relate to a different accounting period and should be treated correctly in the accounts.

The aim is not to force costs into the wrong period. It is to make sure the accounts accurately reflect the business activity before the year-end is closed.

Good records matter here. If an expense is challenged, the business should be able to show what was purchased, why it was for the business, and when the cost was incurred.

3. Consider employer pension contributions

Employer pension contributions can be a tax-efficient way for a company to reward directors or employees, provided they are commercially justified and meet the relevant rules.

HMRC’s pensions tax manual states that tax relief on employer contributions to a registered pension scheme is generally given by allowing the contributions to be deducted as an expense when computing business profits.

However, this is not automatic in every case. HMRC’s business income manual explains that pension contributions must be paid wholly and exclusively for the purposes of the trade to be deductible. It also notes that a pension contribution by an employer to a registered pension scheme for a director or employee will be allowable unless there is a non-trade purpose for the payment.

For owner-managed companies, pension contributions are often worth reviewing before the company year-end because they may reduce taxable profits while moving value into long-term retirement savings.

However, care is needed. Pension planning should take into account:

• available annual allowance
• unused allowance from previous years
• the individual’s pension position
• company cash flow
• whether the contribution is reasonable for the role
• whether there is a clear business purpose
• timing of payment before the year-end

The contribution normally needs to be paid, not simply planned, to obtain relief in the desired accounting period.

This is an area where advice is particularly important, because pension rules can be complex and personal circumstances matter.

4. Review director and shareholder profit extraction

For owner-managed companies, year-end is a natural point to review how profits are being extracted.

This may include salary, dividends, pension contributions, benefits, director’s loan account movements, or a combination of these. The best structure depends on company profits, personal income, other shareholders, available cash and wider personal tax planning.

A review before year-end can help identify issues such as:

• whether dividends are legally available from distributable profits
• whether salary levels remain appropriate
• whether pension contributions should be considered
• whether the director’s loan account is overdrawn
• whether benefits in kind have been properly reported
• whether personal tax payments need to be planned for

This is also a good time to consider the interaction between company tax and personal tax. A company may have one accounting year-end, while individual shareholders are taxed by reference to the UK tax year ending 5 April.

Timing can therefore matter. For example, the date a dividend is declared and paid can affect which personal tax year it falls into.

The goal is not simply to minimise tax in isolation. It is to extract profits in a way that is lawful, documented, cash-aware and aligned with the owners’ personal position.

5. Identify reliefs, claims and compliance issues early

Some tax reliefs require planning, documentation or advance thought. Leaving them until after the year-end can make claims harder to support.

Areas to review may include:

• Research and Development tax relief
• capital allowances
• loss relief
• employment-related reliefs
• bad debt relief
• group relief, where relevant
• VAT and payroll compliance issues
• director’s loan account tax issues
• benefit-in-kind reporting
• whether the company is approaching a Corporation Tax threshold

For companies undertaking qualifying innovation, R&D relief should be considered early. The R&D rules have changed significantly in recent years. HMRC guidance states that if a company’s accounting period begins on or after 1 April 2024, it can claim under the merged R&D scheme or, where applicable, Enhanced R&D Intensive Support.

The important point is not simply whether the company has carried out R&D. It is whether the work meets the tax definition, whether the costs are qualifying costs, and whether the claim can be properly evidenced.

For many businesses, year-end is also a useful time to identify smaller issues before they become larger problems. For example, an overdrawn director’s loan account, missed VAT adjustments, poorly documented staff expenses or unreported benefits may all have tax consequences if left unresolved.

Year-end planning is also about discipline

Tax planning is most effective when it is connected to good management information.

Before year-end, businesses should ideally have:

• up-to-date bookkeeping
• reconciled bank accounts
• a clear view of profit
• reviewed debtors and creditors
• checked payroll records
• reviewed VAT returns
• considered upcoming cash requirements
• identified any unusual transactions

Without this information, tax planning becomes guesswork.

For example, a company may consider buying equipment before year-end, but that decision should be made with a clear view of current profit, cash flow and future needs. Similarly, dividend planning requires accurate information about distributable reserves.

The Corporation Tax thresholds also make accurate forecasting more important. A company close to the £50,000 or £250,000 profit thresholds may need to understand whether marginal relief applies, whether associated companies affect the limits, and whether planned expenditure or pension contributions will change the final tax position.

A practical year-end checklist

Before your business year-end, consider asking:

• Are all business expenses recorded?
• Have any directors or employees paid business costs personally?
• Are there planned purchases that should sensibly happen before year-end?
• Could capital allowances, AIA or full expensing apply?
• Are employer pension contributions worth reviewing?
• Are dividends supported by available distributable profits?
• Is the director’s loan account clear?
• Are there any bad debts that should be reviewed?
• Are there any R&D claims or other reliefs to consider?
• Are VAT, payroll and bookkeeping records up to date?
• Is the company close to a Corporation Tax threshold?
• Is there enough cash set aside for tax?

Summary

Year-end tax planning should be practical, proportionate and commercially sensible.

The most useful steps are often straightforward: review the numbers, capture all allowable costs, consider the timing of planned investment, check profit extraction, and identify any reliefs or compliance issues before the accounting period is closed.

Good planning does not mean spending money simply to reduce tax. It means making informed decisions while there is still time to act.

For many UK companies, a short year-end review with an accountant can help avoid missed opportunities, unexpected tax liabilities and unnecessary pressure after the accounting period has ended.
