End of Tax Year Checklist: What Business Owners Should Do Before 5 April
As the end of the personal tax year approaches on 5 April, business owners have a valuable opportunity to review their finances, optimise tax efficiency, and ensure compliance. Taking action before the deadline can make a significant difference to your tax bill and help position your business strongly for the year ahead.
In this guide, we outline the key areas every business owner should consider before the tax year ends.
1. Review Your Income and Expenses
Start by assessing your income and allowable expenses for the year. Ensuring that all business expenses have been recorded correctly can reduce your taxable profit.
Key actions:
Check for any missing invoices or receipts
Bring forward legitimate expenses where appropriate
Write off bad debts before year-end
Accurate record-keeping not only reduces your tax liability but also prevents issues if HMRC ever reviews your accounts.
2. Make the Most of Your Allowances
The UK tax system offers a range of allowances that reset each year. If you don’t use them, you lose them.
Important allowances to review:
Personal Allowance
Dividend Allowance
Capital Gains Tax Annual Exempt Amount
Pension Allowance
If you operate through a limited company, consider whether you’ve taken a tax-efficient mix of salary and dividends, especially with the rate changes next year (find out more here - Upcoming UK Dividend Tax Changes: Why Acting Before April 2026 Could Save You £650+).
3. Consider Pension Contributions
Making pension contributions before the end of the tax year is one of the most effective ways to reduce your tax bill.
Benefits include:
Tax relief on contributions
Reduction in taxable income
Long-term financial planning
For higher earners, this can be particularly valuable in avoiding higher-rate tax bands.
4. Utilise Capital Allowances
If your business is planning to invest in equipment, vehicles, or machinery, doing so before the tax year ends may allow you to claim capital allowances sooner.
Options to explore:
Annual Investment Allowance (AIA)
Full Expensing (for qualifying companies)
This can significantly reduce your corporation tax bill by offsetting profits.
5. Review Dividend Strategy
If you’re a company director, reviewing your dividend payments before 5 April is essential.
With dividend allowances reduced in recent years, careful planning is required to ensure you:
Stay within lower tax bands where possible
Maximise tax efficiency between spouses (if applicable)
Timing dividend payments correctly can help minimise your overall tax burden.
6. Check Your VAT Position
If your business is VAT-registered, now is a good time to:
Ensure all VAT returns are up to date
Review whether your scheme (e.g. Flat Rate Scheme) is still suitable
Consider timing of invoices to manage cash flow
Small adjustments here can have a noticeable impact on your finances.
7. Plan for Payments on Account
Many sole traders and partners need to make Payments on Account towards their next tax bill.
Before the tax year ends:
Estimate your upcoming tax liability
Set aside funds to avoid cash flow issues
Consider whether payments can be reduced if profits have fallen
8. Use Losses Strategically
If your business has made a loss, there may be opportunities to offset it against:
Previous years’ profits
Other income
Proper use of losses can generate tax refunds or reduce future liabilities.
9. Review Your Business Structure
The end of the tax year is an ideal time to reassess whether your current structure (sole trader, partnership, or limited company) is still the most tax-efficient.
As your business grows, switching structure can sometimes result in substantial tax savings.
10. Seek Professional Advice Early
Tax planning is most effective before the deadline, not after. Working with an accountant ensures you:
Stay compliant with HMRC
Identify tax-saving opportunities
Avoid last-minute stress
