Key Financial Dates for 2025

As we approach the end of 2024, it’s time to start preparing for what’s ahead in the world of bookkeeping and finance. The upcoming year promises a few significant changes, new deadlines and opportunities that could impact on your business operations. In this blog, we will take you through the key financial dates for 2025, explain important changes to keep an eye on, and offer some advice on how to make the most of them. Whether you are self-employed, running a limited company, or just looking to streamline your financial management, it’s essential to stay ahead of the curve. 

1. Start of the New Tax Year - April 6, 2025

The new tax year in the UK begins on April 6th, 2025, marking a fresh start for businesses and individuals. The new tax year brings the opportunity to reset your finances, review your budgets, and get your records in order. If you are a sole trader, limited company owner, or employee, now is the time to check your tax planning and ensure you are ready for the year ahead. 

2. Minimum Wage and National Insurance Changes – April 2025

One of the key changes in 2025 will be the rise in National Minimum Wage and National Insurance contributions for Employers. The UK government announced these changes in the November Budget. 

  • National Minimum Wage (NMW): This applies to all employees and is updated annually. If you employ staff, ensure you are complying with the new rates to avoid penalties. 
  • National Insurance Contributions (NIC): NIC rates will rise in 2025 for Employers. 

These changes can have a direct impact on your payroll costs, and it’s a good idea to review your pay structure and budget now to accommodate these increases. 

Outsourcing – A Smart Move for Businesses

As businesses face rising wage costs and increasing statutory payments, outsourcing key functions like bookkeeping, and social media marketing can be a smart way to streamline operations in 2025. By outsourcing these tasks, you can avoid the complexities of managing employment-related costs such as increased employers’ National Insurance contributions, statutory holiday pay, sick pay, and pension contributions This not only frees up your time to focus on growing your business but also reduces the need to hire additional employees, saving you money on wages, benefits, cover, and overhead costs. Outsourcing allows you to tap into professional expertise without the long-term financial commitment of full or part-time staff, making it a cost-effective solution in the long run. 

Important Deadlines for 2025

1. Self-Assessment Deadline – January 31st, 2025

For self-employed individuals and sole traders, January 31st marks the deadline for submitting your Self-Assessment tax return for the previous tax year. If you haven’t filed by this date, you will face penalties. For 2025, ensure that your records are up to date, and all expenses and income are properly recorded. 

2. Payment on Account – July 31st, 2025

Remember, if your profit exceeds £1,000, you will also be required to make a payment on account by July 31st, 2025. This payment is typically half of your tax liability for the year, so it’s essential to keep track of your finances and set aside money for this deadline. 

3. PAYE Submissions – 22nd of Each Month

For businesses operating under the Pay As You Earn (PAYE) system, the deadline for submitting payroll information is the 22nd of each month. However, it is a good idea to submit your payroll information a few days earlier, we suggest the 19th, to give yourself plenty of time to address any errors or issues that may arise. 

Key Business Deadlines

1. Limited Company Annual Accounts – Year-end plus 9 months

If you run a limited company, you must submit your annual accounts to Companies House within 9 months of your year-end. For example, if your company’s financial year end is 31 March, the accounts must be filed with Companies House no later than 31 December. The exact deadline will depend on when your company’s financial year ends. 

Additionally, don’t forget your Confirmation Statement, which is also due annually. If you don’t know the submission date, check the Companies House website. This document updates Companies House on your company’s structure and shareholders. 

2. ITSA (Income Tax Self-Assessment) Trial – April 26th, 2025

A notable change to look out for in 2025 is the introduction of the Income Tax Self-Assessment (ITSA) digital tax reporting system. From April 2025, HMRC will begin trialing a new system that will eventually replace the traditional self-assessment tax return process. 

Businesses will need to be ready for this transition, which could affect everything from how you file your tax return to how often you need to submit financial information. Be prepared for a shift towards real-time reporting and make sure your accounting software (like Xero, QuickBooks, or Sage) is up to date with the latest developments.  

What’s Ahead? Watch This Space

2025 promises to be a year of transition and change. As HMRC continues to modernise the tax system with the ITSA rollout and other updates, it’s crucial to stay informed and ahead of these developments.
