Key UK Business Tax Reliefs You Need to Know About

When it comes to tax relief, most business owners either don’t realise what they can claim or assume it’s too complicated to bother with. But the truth is, the UK government offers several tax breaks designed to help businesses grow, innovate, and stay financially stable.

Here are some of the most valuable UK Business Tax Reliefs you should know about in 2025—and how they can put more money back into your business.

Business Rates Relief – Lower Your Overheads

If you run a brick-and-mortar business, business rates can be one of your biggest expenses. The Retail, Hospitality, and Leisure (RHL) scheme is continuing in 2025/26, but with a lower discount—the relief has dropped from 75% in 2024 to 40% in 2025, meaning businesses will need to cover more of their rates bill.

✅ Who qualifies? Shops, restaurants, pubs, cafés, hotels, and leisure businesses.
💡 How to claim? Your local council applies the discount automatically—double-check your latest business rates bill.
⏳ What’s changing? The relief has been reduced from 75% to 40%, capped at £110,000 per business.

Employment Allowance – Reduce National Insurance Costs

Hiring staff? You might be overpaying on National Insurance. The Employment Allowance allows eligible businesses to reduce their National Insurance contributions (NICs) by up to £10,500 per year, effective from April 6, 2025.

✅ Who qualifies? All businesses and charities, regardless of size, as the previous £100,000 Employer NIC bill threshold has been removed.
💡 How to claim? Submit your claim via your payroll software when processing your NIC payments.
⏳ What’s changing? From April 6, 2025, the Employment Allowance increases from £5,000 to £10,500, and the eligibility criteria expand to include larger employers due to the removal of the £100,000 Employer NIC bill cap.

Research & Development (R&D) Tax Relief – Stricter Rules for 2025

If your business is developing new products, improving processes, or using technology in an innovative way, you could still benefit from R&D tax relief. However, major changes that took effect in April 2024 mean stricter compliance and new claim requirements in 2025.

✅ Who qualifies? Any business investing in research, product development, or innovative technology.
💡 How to claim? Submit an R&D claim with your Corporation Tax return—or speak to an R&D tax specialist.
⏳ What’s changing?

• Merged R&D Scheme: The SME and RDEC schemes have now been combined into a single scheme with a 20% credit rate.
• Stricter Claim Requirements: First-time claimants must notify HMRC within six months of their accounting period end.
• Overseas R&D Costs Restricted: Most subcontracted R&D work outside the UK no longer qualifies for relief.
• Enhanced R&D Intensive Support (ERIS): SMEs that spend at least 30% of their total expenditure on R&D may qualify for an enhanced tax credit.

Capital Allowances – Full Expensing & AIA in 2025

If you’re investing in your business—buying equipment, machinery, or upgrading your office space—you can deduct these costs from your taxable profit.

Key schemes in 2025:

• Annual Investment Allowance (AIA): Deduct up to £1 million on qualifying assets.
• Full Expensing: Introduced from April 2023, this allows companies to deduct 100% of the cost of new and unused main rate plant and machinery immediately, reducing taxable profits.

✅ Who qualifies? Any UK business investing in qualifying assets.
💡 How to claim? Include capital allowances in your Corporation Tax return.
⏳ What’s changing? Businesses should now use Full Expensing and AIA to maximise tax relief on qualifying investments.

Patent Box – Lower Tax on Profits from Innovations

If your company makes money from patented products or processes, you could pay just 10% Corporation Tax on those profits instead of the standard 25%.

✅ Who qualifies? Businesses that own or license UK patents.
💡 How to claim? Claim through your Corporation Tax return—but be prepared to provide supporting evidence.
⏳ What’s changing? No major changes, but HMRC is paying closer attention to patent box claims, so make sure you have clear proof of eligibility.

VAT Reliefs – Compliance is More Important Than Ever

Certain products and services qualify for reduced VAT rates or exemptions, especially in healthcare, energy efficiency, and charities. However, in 2025, HMRC is tightening VAT compliance, with stricter penalties for late filings and errors.

✅ Who qualifies? Businesses selling VAT-exempt or reduced-rate products, including:

• Charities – Certain goods and services qualify for VAT relief.
• Energy efficiency – A temporary 0% VAT rate applies to energy-saving materials until March 2027, after which it reverts to 5%.

💡 How to claim? Charge the correct VAT rate on sales and ensure proper HMRC reporting.
⏳ What’s changing? Making Tax Digital (MTD) is now mandatory for all VAT-registered businesses, requiring digital records and compliant software. Stricter penalties for late VAT returns, with a points-based system—repeated late submissions lead to financial penalties.
