Corporation tax changes in 2025 are set to impact small and medium-sized enterprises (SMEs) across the UK. Staying informed and prepared is essential to ensure compliance while optimising your tax strategy. In this guide, we’ll break down the key changes, what they mean for your business, and actionable steps to adapt effectively.
Key Corporation Tax Changes in 2025
The UK government has introduced new corporation tax measures to balance fiscal responsibility and economic growth. Here are the most notable updates:
1. New Main Rate of Corporation Tax
The main rate of corporation tax will remain at 25% for businesses with profits exceeding £250,000 annually. However, businesses with lower profits will benefit from a tapered approach:
- Small profits rate (SPR): Companies with profits up to £50,000 will continue to pay a reduced rate of 19%.
- Marginal relief: Businesses with profits between £50,000 and £250,000 can claim marginal relief, reducing their effective tax rate.
2. Changes to Investment Allowances
The Annual Investment Allowance (AIA) cap remains at £1 million, allowing SMEs to offset capital expenditure on equipment, machinery, or technology against taxable profits. Enhanced allowances for green investments and R&D-focused initiatives are also in place, incentivising innovation and sustainability.
3. Digital Tax Compliance Measures
To improve compliance and efficiency, businesses are now required to adopt Making Tax Digital (MTD) for corporation tax. This means submitting digital records and quarterly updates via HMRC-approved software starting April 2025.
How These Changes Impact SMEs
Higher Tax Burden for Profitable Companies
Businesses with profits exceeding £50,000 will experience an incremental tax burden due to the higher rates. For SMEs operating near the £250,000 threshold, strategic planning is crucial to mitigate the impact.
Opportunities for Investment and Innovation
Enhanced allowances for environmentally friendly and R&D investments provide an opportunity for businesses to align tax strategy with long-term growth objectives.
Increased Administrative Requirements
The MTD mandate introduces additional reporting responsibilities. While it simplifies submissions in the long run, it requires initial investment in software and training.
Strategies to Navigate Corporation Tax Changes
1. Review and Optimise Profit Margins
If your profits hover near the £50,000 or £250,000 thresholds, consider strategies to manage taxable income effectively. For instance:
- Accelerate planned expenses to reduce taxable profits.
- Explore the timing of dividends or bonuses.
- Leverage marginal relief calculations to optimise your tax position.
2. Capitalise on Investment Allowances
Take full advantage of the AIA by planning significant purchases before the tax year ends. Consider energy-efficient equipment or R&D projects to maximise tax relief while future-proofing your business.
3. Embrace Digital Tax Compliance
Prepare for MTD by adopting compliant accounting software such as QuickBooks or Xero. Train your team to ensure smooth implementation and avoid penalties for non-compliance.
4. Seek Professional Guidance
Navigating corporation tax changes can be complex. Engaging an accountant, such as the team at Ascentis Accountants, ensures you’re fully compliant and taking advantage of every available relief and allowance.
