As we approach the year end, business owners have a valuable window of opportunity. Strategic decisions made before the calendar year ends, and particularly before the 5th April 2026 tax year-end, can deliver substantial tax savings. Yet many businesses miss these opportunities simply because they’re not aware of them.

At Integra, we help accountancy firms navigate year-end tax planning every December. The clients who plan proactively often save thousands in entirely legal, HMRC-approved ways. Those who wait until their accountant prepares year-end accounts can only work with decisions already made. Let’s explore the strategies you should consider now.

Why year-end tax planning matters

Tax planning isn’t about aggressive schemes or questionable tactics. It’s about understanding the rules and making informed decisions about timing, structure, and available reliefs. Small adjustments, purchasing equipment before year-end rather than after, adjusting your dividend-salary mix, or making pension contributions, can significantly impact your tax bill.

The key is acting before deadlines pass. Once the tax year ends on 5th April, many opportunities close until the following year. December and early January provide the perfect planning window whilst you still have time to implement changes.

Capital allowances: Maximising equipment deductions

One of the most powerful tax planning tools available is the Annual Investment Allowance (AIA). This allows businesses to deduct the full cost of qualifying plant and machinery in the year of purchase, up to £1 million.

What qualifies for AIA? 

Most business equipment counts: computers, machinery, vehicles (with some restrictions on cars), office furniture, and tools. Whether you’re buying a new van, upgrading your IT systems, or purchasing manufacturing equipment, AIA can deliver immediate tax relief.

The timing advantage: Consider you’re planning to spend £30,000 on new equipment. Purchase before 5th April 2026, and you can deduct the entire £30,000 from your 2025/26 profits. For a business paying 25% corporation tax, that’s £7,500 in tax saved. Delay the purchase until April 2026, and that relief shifts to your 2026/27 return, meaning you wait an extra year to benefit.

For unincorporated businesses: Sole traders and partnerships can also claim AIA. If you’re a higher-rate taxpayer (40% or 45%), the timing of equipment purchases becomes even more valuable.

If you’re genuinely planning equipment purchases, bringing them forward before the tax year-end can deliver significant cash flow benefits through reduced tax bills.

Pension Contributions: Tax Relief and Long-Term Planning

Pension contributions remain one of the most tax-efficient ways to extract money from your business whilst building retirement wealth.

For company directors: Your company can make pension contributions on your behalf, which are an allowable business expense reducing corporation tax. Unlike salary, pension contributions don’t attract National Insurance for you or your company, a combined saving of up to 15.05%.

Consider a company making £100,000 profit. Contributing £40,000 to the director’s pension reduces taxable profit to £60,000, saving £10,000 in corporation tax (at 25%). The director receives £40,000 pension funding without paying Income Tax or National Insurance on that amount.

For sole traders and partnerships: Personal pension contributions attract tax relief at your marginal rate. A higher-rate taxpayer contributing £10,000 to their pension only pays £6,000, the government adds £2,000 immediately, and you claim another £2,000 through self-assessment.

Annual allowance considerations: Most people can contribute up to £60,000 annually (including employer contributions and tax relief). If you haven’t used previous years’ allowances, you may be able to carry forward unused allowances from the past three tax years, potentially allowing contributions above £60,000.

However, if your adjusted income exceeds £260,000, the annual allowance tapers down, potentially to as low as £10,000. Professional advice is essential if you’re in this bracket.

The deadline: For sole traders claiming relief in 2025/26, contributions must be made by 5th April 2026. For companies, contributions paid before your accounting year-end can be claimed in that year’s accounts, though you should demonstrate they relate to that period’s profits.

Dividend vs. Salary: Optimising Director Remuneration

If you run a limited company, how you extract profits, salary, dividends, or a combination, significantly affects your tax bill.

The basic principle: Salaries are deductible business expenses but attract Income Tax and National Insurance. Dividends aren’t deductible but are taxed at lower rates and don’t attract National Insurance.

The optimal strategy for most directors: Take a modest salary (often around £12,570 to use your personal allowance, or £9,100 to avoid employer National Insurance) and extract the remainder as dividends.

Dividend tax rates for 2025/26: The first £500 of dividends are tax-free (the dividend allowance). Beyond that, you pay:

• 75% if you’re a basic-rate taxpayer
• 75% if you’re a higher-rate taxpayer
• 35% if you’re an additional-rate taxpayer

Year-end considerations: Review your projected income for 2025/26. If you’re approaching the higher-rate threshold (£50,270), it might be worth deferring dividends until the new tax year to keep more income in the basic-rate band.

Conversely, if you’ve had a lower-income year, you might want to declare additional dividends before 5th April to utilise your personal allowance and basic-rate band efficiently.

Company profit timing: Remember that dividends must be paid from distributable profits. If your year-end accounts aren’t yet finalised, you’ll need to be confident profits support the dividend declaration.

Strategic timing of income and expenses

Sometimes, small timing adjustments can produce material tax benefits.

Deferring income: If you’re approaching the end of your accounting period and income is unexpectedly high, consider whether any invoicing could legitimately be delayed until the new accounting period. This is particularly relevant if you expect lower profits next year or anticipate tax rate changes.

Accelerating expenses: Conversely, if you have business expenses planned for early next year, bringing them forward to before year-end increases this year’s deductions. This might include paying annual subscriptions, prepaying rent, or completing maintenance work.

Legitimate commercial reasons: Any timing adjustments must have genuine commercial justification. HMRC takes a dim view of purely tax-motivated arrangements without business substance.

Capital Gains Tax planning

If you’re planning to sell business assets or investments, timing can significantly affect your CGT bill.

Your annual exemption: Each individual has a CGT annual exempt amount (£3,000 for 2025/26). This is use-it-or-lose-it, if you don’t make gains up to this amount, you can’t carry the exemption forward.

Splitting disposals: If you’re selling assets with substantial gains, consider whether you can split the disposal across two tax years to utilise exemptions in both years.

Business Asset Disposal Relief: If you’re selling all or part of a business you’ve owned for at least two years, you may qualify for Business Asset Disposal Relief (formerly Entrepreneurs’ Relief), which taxes gains at just 10% on the first £1 million of lifetime gains.

Timing considerations: CGT is payable by 31st January following the tax year of disposal. Selling in March 2026 gives you until January 2027 to pay the tax, ten months’ breathing space compared to selling in April 2025.

Making charitable donations

Charitable giving through your business can be tax-efficient whilst supporting causes you care about.

Company donations: Companies can make charitable donations that reduce taxable profits. There’s no limit on the amount, provided the donation has a qualifying charitable purpose.

Gift Aid for personal donations: Sole traders and individuals can make Gift Aid donations. The charity claims 25p for every £1 you donate, and higher-rate taxpayers claim back the difference between basic and higher rate through their tax return.

Year-end is an excellent time to review whether charitable giving might form part of your tax planning strategy.

Taking action before year-end

Effective year-end tax planning requires action, not just awareness. Here’s your action plan:

Week 1-2 (Early December): Review your projected profits for the year. Consider whether equipment purchases, pension contributions, or director remuneration changes could reduce your tax bill.

Week 3 (Mid-December): Consult with your accountant. At Integra, we help clients model different scenarios, showing exactly how various strategies affect their tax position. Professional advice ensures you’re making informed decisions compliant with all regulations.

Week 4-5 (Late December-Early January): Implement your chosen strategies. Process pension contributions, make equipment purchases, or adjust your dividend declarations before the tax year ends on 5th April.

Before 5th April: Final review. Ensure all planned actions are completed and documented appropriately.

Common mistakes to avoid

Acting without advice: Tax planning can be complex. What works for one business may be inefficient or inappropriate for another. Always seek professional guidance.

Artificial arrangements: HMRC scrutinises arrangements that lack commercial substance. Every decision should be justifiable on business grounds, not purely tax motivation.

Missing documentation: Whatever strategies you implement, document the decisions and retain evidence. If HMRC enquires, you’ll need to demonstrate compliance.

Forgetting about VAT and other taxes: Focusing solely on corporation tax or income tax whilst ignoring VAT implications can lead to unpleasant surprises.

People Also Ask

Q1. When should I start tax planning for my business?
A1. Year-end tax planning should begin in December, giving you time to implement strategies before the 5th April tax year-end. However, effective tax planning is an ongoing process throughout the year, with quarterly reviews ensuring you maximise opportunities and avoid surprises at year-end.

Q2. What is the Annual Investment Allowance for 2025/26?
A2. The Annual Investment Allowance (AIA) allows businesses to deduct 100% of qualifying plant and machinery costs up to £1 million in the year of purchase. This applies to most equipment including computers, machinery, and commercial vehicles, providing immediate tax relief rather than spreading over multiple years.

Q3. How much can directors save by taking dividends instead of salary?
A3. Directors typically save 13.8% employer’s NI plus employee NI (up to 12%) by taking dividends instead of salary above the NI threshold. However, dividends aren’t deductible for corporation tax. The optimal mix usually involves a modest salary (around £9,100-£12,570) plus dividends, saving thousands annually.

Q4. Can I backdate pension contributions for tax relief?
A4. Pension contributions must be made by 5th April to qualify for that tax year’s relief. You cannot backdate contributions after the tax year ends. However, you may be able to carry forward unused annual allowances from the previous three tax years, potentially allowing larger contributions.

Q5. What expenses can I claim before year-end to reduce tax?
A5. You can claim legitimate business expenses incurred before year-end including equipment purchases (via AIA), professional fees, repairs and maintenance, prepaid expenses like insurance or subscriptions, marketing costs, and staff costs. All expenses must be wholly and exclusively for business purposes.
