The UK Government released its Spring Budget 2025, outlining important changes impacting businesses, accountants, and individuals. At TwinTallies, we’ve reviewed the budget to highlight what matters most to you — from tax updates to incentives and compliance changes.
Here’s a quick, clear breakdown:
Top 5 Budget Highlights You Need to Know
1. Corporation Tax Frozen at 25% No increases this year. Companies with profits under £50,000 continue to pay the small profits rate of 19%.
2. Full Expensing Extended The 100% capital allowance on qualifying plant and machinery has been made permanent. A big win for businesses investing in equipment or tech infrastructure.
3. VAT Registration Threshold Raised The VAT threshold rises from £85,000 to £90,000, easing the burden for small businesses.
4. National Insurance Cut Continues Employee NICs reduced from 10% to 8%, and self-employed Class 4 NICs fall to 6%. This change is set to boost take-home pay.
5. R&D Tax Relief Simplified A merged scheme is introduced for all SMEs and large businesses, improving access to innovation funding with fewer barriers.
What This Means For You?
• Accounting Firms: Consider advising clients on capital investment strategies to take advantage of full expensing.
• Small Businesses: Reassess VAT registration plans and evaluate NIC savings in payroll planning.
• Startups: The R&D changes can unlock more funding and simpler claims — especially for tech or product-driven firms.
