Tax planning is one of the most critical aspects of running a successful business. With the right strategies in place, you can legally minimise your tax liability and keep more money in your business to fuel growth.

Understanding Tax Planning Basics

Tax planning isn't just about filing your returns on time - it's about proactively managing your financial affairs throughout the year to optimise your tax position. This involves understanding allowable expenses, reliefs, timing strategies, and the implications of different business structures.

Key Strategies for 2026

1. Maximise Allowable Business Expenses

One of the simplest ways to reduce your tax burden is to ensure you're claiming all allowable expenses. Common deductible expenses include:

• Home office costs (flat rate or actual cost method)
• Business mileage or actual vehicle running costs
• Professional development and training
• Business insurance premiums
• Pension contributions
• Accountancy fees
• Software, equipment, and tools used for business

2. Timing Income and Expenses

Strategic timing can significantly impact your tax liability. Consider:

• Bringing forward planned expenses into the 2026/27 tax year
• Delaying invoicing until after 6 April 2027 if you expect lower income next year
• Managing dividend payments to stay within lower tax bands

These decisions should be made with cash flow and longterm planning in mind.

3. Choose the Right Business Structure

Your business structure has major tax implications. For example:

• Sole traders pay Income Tax and Class 2/4 National Insurance on profits.
• Limited companies pay Corporation Tax (still at 25% for most companies as at April 2026) and allow owners to take a combination of salary and dividends.
• Partnerships offer flexibility but may be less taxefficient at higher profit levels.

Review your structure annually as your business grows.

4. Leverage Pension Contributions

Pension contributions remain one of the most powerful taxefficient strategies in 2026. Options include:

• Personal pensions
• Employer pension contributions through your limited company
• Selfinvested personal pensions (SIPPs)

The annual pension allowance remains £60,000 for 2026/27, with carryforward available.

Employer contributions are typically deductible for Corporation Tax and do not attract National Insurance.

Year-End Tax Checklist (Before 5 April 2027)

Use this checklist to make sure you've covered all your bases before the end of the 2026/27 tax year:

• ✔
  Review your financial statements

  Ensure your bookkeeping is up to date. Reconcile bank accounts, review income and expenses, and correct any discrepancies before your accountant begins yearend work.

• ✔
  Maximise capital allowances

  As at April 2026:

  • The Annual Investment Allowance (AIA) remains at £1 million.
  • Full expensing continues for qualifying plant and machinery for companies.
  • Special rate assets qualify for a 50% firstyear allowance.
• ✔
  Check payroll and subcontractor payments

  • Ensure PAYE records are accurate.
  • Verify that all subcontractors under the Construction Industry Scheme (CIS) have been correctly processed.
  • Issue P60s by 31 May 2027 and P11Ds by 6 July 2027 if applicable.
• ✔
  Evaluate depreciation and capital allowance strategy

  Work with your accountant to determine whether AIA, writingdown allowances, or full expensing is most beneficial.

• ✔
  Contribute to pensions

  Maximise pension contributions before 5 April 2027 to reduce taxable income. The annual allowance remains £60,000, with carryforward available.

• ✔
  Review payments on account

  Ensure your payments on account reflect your actual income. If profits have fallen, you may be able to reduce them. If you've underpaid, plan for the balancing payment due 31 January 2027.

• ✔
  Organise receipts and records

  Gather documentation for all deductible expenses, including mileage logs, home office calculations, and receipts for equipment or software.

• ✔
  Assess your business structure

  If your profits have grown, incorporation or restructuring may reduce your tax burden. For limited companies, review your salary/dividend mix in light of the 2026 dividend allowance, which remains at £500.

• ✔
  Consult your accountant

  Schedule a yearend review before 5 April 2027 to implement any lastminute tax strategies while there's still time.

Working with a Tax Professional

While understanding these strategies is valuable, working with a qualified accountant can help you implement them effectively and uncover additional opportunities specific to your business. A professional can also help you stay compliant with changing UK tax laws and regulations.

Action Steps

To get started with tax planning for your business:
