Understand Your Company’s Tax Structure

For small limited companies: Corporation Tax is 25% for profits over £250,000 and 19% for profits of £50,000 or less, with marginal relief in between. For sole traders, taxable profits are subject to Income Tax and Class 4 National Insurance. The Personal Allowance remains £12,570 for both 2024/25 and 2025/26.

Use Salary and Dividends Wisely (Ltd companies)

Balancing salary and dividends can reduce overall tax and NICs. The dividend tax-free allowance is now £500 from 6 April 2024. Dividends are not subject to NICs, while salaries are. Pay a modest salary (up to personal allowance or NIC threshold) and take surplus as dividends.

Claim All Allowable Business Expenses

Both limited companies and sole traders should claim all allowable expenses (office costs, travel, subscriptions, professional fees, marketing). Keep digital receipts and accurate records to meet HMRC requirements.

Capital Allowances & Annual Investment Allowance (AIA)

Capital allowances let you claim relief on plant and machinery. The AIA limit remains £1 million, allowing full 100% deduction on qualifying purchases.

Employment Allowance & Pension Contributions

Employment Allowance remains £5,000 for 2024/25 and increases to £10,500 from 6 April 2025. Employer pension contributions reduce taxable profits and are free from NICs, making them highly tax-efficient.

VAT: Registration Threshold & Flat Rate Scheme

The VAT registration threshold rose to £90,000 from 1 April 2024 (deregistration £88,000). The Flat Rate Scheme remains available for businesses with turnover under £150,000.

Late Payment Interest & Penalties

From 6 April 2025, HMRC will charge late payment interest at the Bank of England base rate + 4%. Paying taxes and filing returns on time helps avoid expensive penalties.

R&D Tax Credits & Other Reliefs

Companies carrying out qualifying R&D activities can claim enhanced relief or payable credits. Eligible work includes developing new products, processes, or solving technical uncertainties.
