Self-Employed Tax Planning Tips | Maximize Savings 2026

1. Maximize Your Allowable Expenses

The most fundamental tax planning strategy is to claim every expense you are entitled to. Many self-employed individuals miss out on legitimate claims.

• Review Your Expenses: Go through your bank statements and receipts to ensure you haven’t missed any business costs.
• Home Office: Claim your Home Office Expenses using either the flat rate or actual cost method.
• Mileage: Claim Mileage Claims for all business travel.
• Technology: Claim for laptops, software, and website costs. See our guide on Equipment Purchases.
• Insurance: Don’t forget to claim business insurance premiums. See our guide: Insurance Costs.
• Professional Fees: Accountant fees are fully deductible.

2. Consider Pension Contributions

Pension contributions are one of the most tax-efficient ways to save. They reduce your adjusted net income, which can reduce your Income Tax bill and may also protect your Personal Allowance.

• Get Tax Relief: For every £100 you pay into your pension, the cost to you can be as low as £60 if you’re a higher-rate taxpayer.
• Annual Allowance: You can contribute up to £60,000 per year (subject to tapering for high earners) and receive tax relief. See our guide: Pension Contributions.

3. Use Your Personal Allowance

Everyone has a Personal Allowance (£12,570 for 2025-26). If your total income is below this amount, you pay no tax. If your profits fluctuate, consider adjusting the timing of your income or expenses to keep your income below the threshold.

4. Consider the Cash Basis of Accounting

The Cash Basis vs Traditional Accounting can be a powerful tax planning tool. Under the cash basis, you only pay tax on money you’ve actually received, not on invoices you’ve issued. This can be particularly beneficial for cash flow.

5. Claim the Marriage Allowance

If you are married or in a civil partnership and one of you is a non-taxpayer, you can transfer up to £1,260 of your Personal Allowance to your spouse or partner. This could save you up to £252 in tax.

6. Capital Allowances

If you need to buy equipment, consider the timing of the purchase. The AIA limit is £1,000,000 until 31 March 2026. After that, it drops to £200,000. Buying before this date could allow you to claim a larger deduction. See our guide: Equipment Purchases.

7. Use Your ISA Allowance

Your Individual Savings Account (ISA) allowance is £20,000 per year. Any income or capital gains within an ISA are completely tax-free. While this doesn’t reduce your tax bill directly, it’s a highly effective way to grow your wealth tax-efficiently.

8. Plan Around the Tax Year End

The tax year ends on 5 April. Planning around this date can be highly beneficial:

• Accelerate Expenses: If you know you need to make a purchase, consider doing it before 5 April to get the tax deduction in the current tax year.
• Delay Income: If you can, consider delaying invoicing until after 5 April so the income falls into the next tax year. This can be useful if you expect to be in a lower tax band next year.

9. Manage Payments on Account

HMRC may require you to make ‘Payments on Account’ towards your next year’s tax bill. If your income has fallen, you can apply to reduce these payments. Conversely, if your income is increasing, consider making voluntary payments to avoid a large bill later.

10. Seek Professional Advice

Tax planning is a complex area. The rules change frequently, and what works for one person may not be right for another. A qualified accountant can help you:

• Identify savings: Find deductions and reliefs you might have missed.
• Plan ahead: Develop a year-round tax strategy.
• Stay compliant: Ensure you are using the rules correctly and avoiding penalties.
