Essential End-of-Year Tax Checklist for Small Businesses
As the end of the tax year approaches, small business owners across the UK are gearing up for a crucial time. It’s the perfect moment to make sure your finances are in check, ensuring you’re not just scrambling at the last minute. Proper preparation can help you maximise tax efficiency, avoid nasty penalties, and set your business up for a smooth start to the new financial year. Here’s a checklist to guide you through the essentials!
1. Review Your Financial Records
Before submitting your tax return, ensure your books are accurate and up to date. Check for any missing invoices, expenses, or errors in your accounts. Using accounting software like Xero or QuickBooks can make this process easier.
2. Chase Outstanding Invoices
Unpaid invoices can impact your cash flow and financial reports. Follow up with any clients who haven’t settled their accounts to ensure you enter the new tax year with a clean slate.
3. Maximise Allowable Expenses
Make sure you’ve claimed all eligible business expenses, including:
- Office supplies and equipment
- Travel and mileage costs
- Professional fees (e.g., accountants, solicitors)
- Home office expenses (if you work from home)
- Training and development costs
Every deduction reduces your taxable profit, so don’t leave money on the table!
4. Use Your Annual Investment Allowance (AIA)
If you’ve been planning to invest in new equipment, IT systems, or business vehicles, now is the time. The AIA allows businesses to deduct the full cost of qualifying assets from their taxable profits, but it resets annually.
5. Pay Into Your Pension
Contributions to a pension scheme can be a tax-efficient way to save for the future while reducing your tax liability. Check if you’ve used your pension allowance for the year and consider making additional contributions before the deadline.
6. Check Your Dividend and Salary Strategy
If you’re a company director, review how you’ve taken income this year. A combination of salary and dividends can be a tax-efficient way to pay yourself, but be mindful of tax thresholds and allowances.
7. Review VAT Returns and Deadlines
If your business is VAT-registered, ensure all returns are submitted correctly and on time. Also, check if you’re close to the VAT registration threshold (£90,000 from April 2024) if you’re not already registered.
8. Plan for Corporation Tax
Corporation Tax rates increased in 2023, with businesses earning over £50,000 facing a higher rate. Make sure you’ve set aside enough to cover your liability and consider any tax reliefs you might be eligible for.
9. Prepare for the Self-Assessment Deadline
If you’re self-employed or a director of a limited company, your Self-Assessment tax return for the 2023/24 tax year was due by 31st January 2025. If you were struggling to meet the deadline this year, now is the time to think ahead to avoid last-minute stress for the next tax return.
10. Speak to Your Accountant
A professional accountant, like Perk Accounting, can help you identify tax-saving opportunities and ensure you comply with HMRC regulations. If you don’t already work with one, now is a great time to seek expert advice.

Taking the time to review your finances before the end of the tax year can help you save money, avoid penalties, and enter the next financial year with confidence. Whether it’s maximising deductions, reviewing cash flow, or planning for upcoming tax changes, good preparation is key to running a financially healthy business.
