2025 UK Tax-Saving Tips

• Submit your tax return on time to avoid late submission penalties. With digital submission becoming mandatory from April 2026, late filings and missed submissions will be penalised under the new system.

• E- File your tax return and use The Tax Form Calculator to estimate your tax liability and a possible refund

•  Keep business and personal finances separate. Open a business bank account, and you can deduct the bank charges as an expense.

•  Invest in modern software and track your business mileage.

•  Submit a healthy tax return by deducting your private health insurance from your tax bill if you are a director of a limited company, insure also your employees, sole trader with employees or contractor working through a limited company

•  Tidy up your files and paperwork

• Allocate money for taxes each month

• Set up a retirement plan. If you are self-employed, you make contributions to an occupational pension scheme, such as Nest, and the government backs them up by making additional contributions of 25p for every contributed pound. For the higher tax ratepayers, there is additional tax relief.  

• Make sure that you claim all tax-deductible expenses. Below is a list of what you can claim.
