Why Waiting Until April Is the Most Expensive Mistake UK Business Owners Make
Every April, thousands of UK business owners find themselves rushing to update their accounts, chase missing receipts and make important financial decisions at the last possible moment.
The problem is that by April, some of the most useful tax-planning opportunities may already have passed. For small business owners and limited company directors, the difference between a manageable tax bill and an unnecessarily high one can often come down to when you plan, not just what you do.
Directors who review their financial position in January or February still have time to consider salary and dividend levels, pension contributions, capital expenditure and other tax-planning opportunities. Those who wait until the final days of the tax year may have far fewer options.
For the 2026/27 tax year, the UK tax year ends on 5 April 2027.
This guide explains the key areas small business owners and limited company directors should review before the tax year ends, so they can make informed decisions rather than relying on last-minute guesswork.
At TX Accountants Ltd, we provide comprehensive accounting and tax support, including Self Assessment, Partnership Tax Returns, Limited Company accounts, bookkeeping and cloud accounting solutions.
Year-End Tax Planning for Small Businesses: 2026/27 Guide
The High Cost of Reactive Tax Planning
Year-end tax planning isn’t simply about submitting your tax return before the deadline. There is an important difference between tax compliance and tax planning. Tax compliance means meeting your legal obligations, keeping appropriate records and submitting the required returns.
Tax planning is more proactive. It means reviewing your financial position early enough to understand your options and make decisions that could improve your overall tax position.
The UK tax year runs from 6 April to 5 April. For 2026/27, that means the tax year runs from 6 April 2026 to 5 April 2027. Before the tax year ends, business owners should consider:
- Salary and dividends
- Business profits
- Allowable expenses
- Pension contributions
- Capital expenditure
- Corporation Tax
- Personal tax exposure
- Capital Gains Tax
- Cash reserves
- Bookkeeping
- Available tax allowances and reliefs
The earlier you review these areas, the more time you have to make sensible decisions.
1. Review Your Director Salary and Dividend Strategy
If you operate through a limited company, deciding how to take money from your company is an important part of limited company tax planning.
Salary and dividends are taxed differently, so the most suitable combination depends on your individual circumstances, company profits, National Insurance position and other income.
For 2026/27, the Personal Allowance is £12,570, subject to the usual rules. The basic Income Tax rate for most UK taxpayers is 20%, with higher rates of 40% and 45%.
Dividends are taxed separately. From 6 April 2026, dividend tax rates above the £500 dividend allowance are:
- 10.75% for basic-rate taxpayers
- 35.75% for higher-rate taxpayers
- 39.35% for additional-rate taxpayers
Why Dividend Planning Matters
It is easy to assume that taking dividends is always the most tax-efficient option.
In reality, your circumstances need to be considered carefully.
Your salary and dividend strategy can depend on:
- Total company profits
- Your other personal income
- Income Tax bands
- National Insurance
- Corporation Tax
- Employment Allowance
- Pension plans
- Your personal financial position
- Whether profits should remain in the company
Before declaring additional dividends, make sure the company has sufficient distributable profits and that the dividend is properly documented.
Plan Dividends Before the Tax Year Ends
The timing of a dividend can affect your personal tax position.
If you’re considering taking a dividend before 5 April, review your expected income and tax position first. Depending on your circumstances, it may be appropriate to take income earlier, delay it or leave profits within the company.
The important point is to plan before making the decision, rather than trying to fix the position afterwards.
2. Understand Your Corporation Tax Position
Corporation Tax is another major consideration when carrying out year-end tax planning for a limited company.
For financial years starting in 2026, the main Corporation Tax rate is 25%.
Companies with profits of £50,000 or less generally qualify for the 19% Small Profits Rate, while companies with profits between £50,000 and £250,000 may benefit from Marginal Relief.
These thresholds can be affected by factors such as associated companies and short accounting periods.
So don’t focus only on turnover.
Before the end of your accounting period, review:
- Estimated taxable profit
- Allowable business expenses
- Capital expenditure
- Pension contributions
- Corporation Tax already paid
- Corporation Tax expected to be due
- Dividends declared
- Associated companies
- Available tax reliefs
Accurate bookkeeping is essential because incomplete or outdated financial information can make it difficult to estimate your actual tax position.
3. Consider Capital Expenditure and the Annual Investment Allowance
Planning to purchase new computers, equipment, machinery or other assets for your business?
Year-end is a good time to review your planned capital expenditure.
The Annual Investment Allowance (AIA) can allow businesses to claim 100% relief on qualifying plant and machinery expenditure, subject to the relevant rules, up to an annual limit of £1 million.
Potential qualifying purchases can include:
- Computers and laptops
- Office equipment
- Machinery
- Tools
- Business fixtures
- Certain commercial equipment
However, not every asset qualifies.
For example, business cars are generally subject to different capital allowance rules.
Should You Buy Equipment Before Year-End?
Don’t purchase equipment simply because you want a tax deduction.
Ask yourself: Does the business genuinely need it?
If the purchase makes commercial sense, the timing of the expenditure may affect when the relevant tax relief becomes available. Before making a significant purchase, your accountant can help determine whether the asset qualifies and which capital allowance treatment may apply.
4. Review Pension Contributions
Pension contributions can form an important part of tax planning for company directors and business owners. Where the relevant conditions are met, employer pension contributions may be an allowable business expense and could reduce a company’s taxable profits.
For 2026/27, the standard pension annual allowance is £60,000, although the amount available to an individual can vary depending on their circumstances.
You may also be able to use unused pension allowance from previous years through the carry-forward rules, subject to the relevant conditions.
Before Making a Large Pension Contribution, Check:
- Your available annual allowance
- Any unused allowance from previous years
- Your income
- Whether the contribution is personal or made by the company
- Your company’s financial position
- Whether the contribution is appropriate for your circumstances
A pension contribution should form part of a wider financial plan rather than being made simply because the tax year is ending.

5. Review Your Allowable Business Expenses
It’s easy to overlook legitimate business expenses during the year. Before your accounts are finalised, review your records and make sure you’ve captured genuine business costs correctly. Depending on your circumstances, these may include:
- Professional fees
- Accounting costs
- Business insurance
- Office expenses
- Software subscriptions
- Business travel
- Phone and internet costs
- Marketing expenses
- Training and development
- Equipment and other business purchases
Keep appropriate records and receipts, and make sure expenses are genuinely related to the business.
Don't Spend Money Just to Reduce Your Tax Bill
This is one of the most important principles of sensible tax planning. Spending £1 to save a fraction of that amount in tax doesn’t make financial sense. The objective is not to spend more money. The objective is to make sure you’re claiming the tax reliefs you’re legitimately entitled to on expenditure your business actually needs.
6. Check Your Personal Tax Position
Your year-end planning shouldn’t stop with your company.
If you’re a director or business owner, your personal tax position may include income from several different sources.
Consider:
- Salary
- Dividends
- Employment income
- Rental income
- Pension income
- Savings income
- Capital gains
- Benefits
- Other taxable income
The Personal Allowance is £12,570 for 2026/27, subject to the relevant rules, and it is reduced for individuals with adjusted net income above £100,000.
This makes planning particularly important for directors approaching or exceeding £100,000 of income.
A change in income can affect your tax position and the availability of certain allowances.
7. Don't Forget Capital Gains Tax
Capital Gains Tax is another area that business owners should consider before the end of the tax year. If you’re planning to sell investments, shares, or business assets, the timing of the disposal can matter. The Annual Exempt Amount is £3,000 for 2026/27. Before selling an asset, consider:
- The expected gain
- Your Income Tax position
- The type of asset
- Available reliefs
- Your Annual Exempt Amount
- The timing of the disposal
Capital Gains Tax can become particularly complicated when selling business assets or company shares. If you’re considering a significant sale, seek professional advice before completing the transaction.
8. Get Your Bookkeeping Up to Date
Effective tax planning depends on accurate financial information. If your bookkeeping is several months behind, it can be difficult to know your actual:
- Business profit
- Tax liability
- Cash position
- Outstanding expenses
- Customer balances
- Supplier balances
Before the tax year ends, make sure you:
- Reconcile your bank accounts
- Record all business income
- Capture outstanding expenses
- Check unpaid invoices
- Review supplier balances
- Record payroll correctly
- Review your director’s loan account
- Categorise transactions correctly
- Gather receipts and supporting documents
Cloud accounting software can make this easier by keeping your financial information organised and accessible throughout the year. The goal isn’t simply to produce accounts after the year has ended. The goal is to have reliable financial information before the deadline so you can make better decisions while there is still time to act.

Common Year-End Tax Planning Mistakes
Leaving Everything Until April
Waiting until the final days of the tax year can leave you with very few options. Some decisions need to be planned before the transaction takes place, particularly when dealing with pensions, dividends, investments and significant purchases.
Assuming Every Expense Is Tax Deductible
Not every purchase qualifies for tax relief. Expenses must meet the relevant tax rules, while capital expenditure may need to be dealt with through capital allowances.
Taking Dividends Without Checking Your Profits
Having money in the company’s bank account doesn’t automatically mean that you can take it as a dividend. Dividends generally need to be supported by sufficient distributable profits and properly documented.
Buying Equipment Just for the Tax Deduction
Tax relief shouldn’t be the reason for making an unnecessary purchase. A business purchase should make commercial sense first.
Ignoring Income Outside the Company
Salary and dividends may not be your only sources of taxable income. Employment income, property income, savings, investments and other income can affect your overall tax position.
Using Outdated Tax Rates
Tax rates and allowances change. For 2026/27, the dividend ordinary rate has increased from 8.75% to 10.75%, while the higher dividend rate has increased from 33.75% to 35.75%. Using outdated information when planning your finances could result in poor decisions.
When Should You Start Year-End Tax Planning?
The best time to start is months before the tax year ends — not on 5 April.
For 2026/27, the tax year ends on 5 April 2027.
Ideally, business owners should monitor their financial position throughout the year and carry out a more detailed review as the year-end approaches.
Starting early gives you time to:
- Estimate final income and profits
- Identify potential tax liabilities
- Review salary and dividends
- Consider pension contributions
- Plan capital expenditure
- Check available allowances and reliefs
- Fix bookkeeping issues
- Review your personal tax position
- Make informed financial decisions
The earlier you start, the more options you may have.
