This blog post aims to guide you through the essential dates and provide practical tips to help you prepare effectively for the end of the financial year. Timely planning can not only help in optimizing tax liabilities but also in enhancing your financial health for the upcoming year.

Key Dates in the 2024/2025 Tax Year

April 5, 2025: This date marks the end of the 2024/2025 tax year. It’s the final day to utilize your tax allowances and reliefs for the year.

April 6, 2024: The start of the 2024/2025 tax year. It’s crucial to start planning early in the year to fully utilize your tax allowances and reliefs.

July 31, 2024: This is the deadline for your second ‘payment on account’ for the 2023/2024 tax year. This payment is an advance payment towards your tax bill (including Class 4 National Insurance if you’re self-employed).

October 31, 2024: Deadline for paper self-assessment tax returns for the 2024/2025 tax year.

January 31, 2025: Final deadline for online self-assessment tax returns for the 2024/2025 tax year. This date is also the deadline for your first ‘payment on account’ for the 2025/2026 tax year.

Tips for Businesses

  1. Review Your Accounts: Ensure that your accounts are up to date. This will give you a clear view of your profits for the year and help in accurate tax calculations.
  2. Maximize Capital Allowances: Invest in business assets before the year-end to claim capital allowances. This could include equipment, vehicles, or machinery necessary for your business.
  3. Research Available Reliefs: Various tax reliefs are available, such as Research and Development (R&D) relief. Investigate if your business activities could qualify for such reliefs.
  4. Manage Your Profits: If your business income is likely to cross the higher tax threshold, consider ways to defer income or accelerate expenses to manage your tax rate effectively.
  5. Pension Contributions: Consider making pension contributions from your business to reduce your corporation tax liability.
  6. Dividend Planning: If you operate through a limited company, review your dividend strategy to optimize your personal tax position.

Tips for Individuals

  1. Utilize Your ISA Allowance: You have until April 5 to use your annual Individual Savings Account (ISA) allowance. ISAs offer tax-free growth and can be an excellent way to save.
  2. Pension Contributions: Consider increasing your pension contributions before the year-end. Pension contributions can reduce your overall taxable income and potentially bring you below critical tax thresholds.
  3. Charitable Donations: Charitable donations can reduce your taxable income. If you plan to donate, doing so before the year-end can be beneficial for tax purposes.
  4. Capital Gains Tax (CGT): Review your investments for any capital gains or losses. You have an annual CGT allowance, and it’s crucial to use it effectively.
  5. Inheritance Tax (IHT) Planning: Consider making gifts to utilize your annual IHT exemption. Gifts made out of your income, not capital, can immediately be free of IHT.
  6. Check Your Tax Code: Ensure your tax code is correct. A wrong tax code could mean you’re paying more or less tax than you should.

Timeline for End of Year Planning

April to June: Review your previous year’s tax return for insights. Begin tax planning for the current year.

July to September: Update and review your financial records. Prepare for your ‘payment on account’ if applicable.

October to December: Finalize tax strategies and make any necessary year-end transactions. Prepare for the paper self-assessment tax return deadline.

January: Ensure all records are up to date. File your online self-assessment tax return and make your ‘payment on account’.

February to March: Review your ISA and pension contributions. Make any final year-end financial moves.


Effective year-end financial planning requires foresight and organization. By being aware of key dates and implementing the tips provided, both businesses and individuals can position themselves favorably for the end of the 2024/2025 tax year. Remember, consulting with a professional accountant or tax advisor can provide tailored advice specific to your circumstances.
