21/01/2026
Reading Time:
Running a small business in the UK can be rewarding, but tax rules can sometimes feel overwhelming. Knowing which reliefs you qualify for can make a big difference to your cash flow and long‑term growth. From capital allowances to research incentives, there are numerous ways to legally reduce your tax bill and reinvest in your business growth.
As experienced small business accountants, we’ve created this guide to help you identify, claim, and maximise small business tax reliefs available in 2025/26.
What is small business tax relief?
Small business tax relief refers to a range of government schemes that help reduce the amount of tax paid by small companies and sole traders.. These reliefs are designed to encourage investment, innovation, and growth by supporting entrepreneurs with financial flexibility.
You may qualify for different forms of relief depending on your business size, turnover, and structure — such as whether you’re a limited company, sole trader, or partnership.
Main categories of tax reliefs include:
- Income and corporation tax reliefs – for reducing taxable profits.
- Investment and innovation reliefs – for businesses developing new products or technologies.
- Property and rate reliefs – for companies operating from commercial premises.
- Employment-related reliefs – for those hiring staff or paying pensions.
PAYE and salary-related tax reliefs for directors
If you pay yourself a salary from your limited company, there are several ways to structure it efficiently under the PAYE system. In 2025/26, you can earn up to £12,570 before paying income tax — thanks to the personal allowance. However, National Insurance (NI) contributions apply once you exceed the Primary Threshold (£12,570) or the Lower Earnings Limit (£6,396) for pension eligibility.
| Tax Band 2025/26 | Taxable Income | Tax Rate |
|---|---|---|
| Personal Allowance | Up to £12,570 | 0% |
| Basic Rate | £12,571 – £50,270 | 20% |
| Higher Rate | £50,271 – £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
Tip: Many small business owners choose to set their salary between the Lower Earnings Limit and the Primary Threshold to maintain NI credits without paying NI, and then take additional income as dividends.
Capital allowances and equipment investment
When your business buys assets like computers, machinery, or office furniture, you can claim capital allowances to deduct their cost from taxable profits. The key type of capital allowance is the Annual Investment Allowance (AIA), which lets you claim 100% tax relief on qualifying purchases up to £1 million per year.
Examples of qualifying assets include:
- Office furniture and IT equipment
- Commercial vehicles and tools
- Machinery and fixtures in business premises
| Capital Allowance Type | Relief Description | Claim Limit |
|---|---|---|
| Annual Investment Allowance (AIA) | 100% relief on most business assets | Up to £1,000,000 |
| Writing Down Allowance (WDA) | For assets not fully deducted under AIA | 18% (main rate) or 6% (special rate) |
| Full Expensing (until 2026) | 100% relief on qualifying plant & machinery | No limit for eligible companies |
Tip: In most cases, it’s more efficient to use AIA before claiming WDA.
Small business rates relief (SBRR)
Businesses operating from commercial premises may qualify for Small Business Rates Relief (SBRR). This relief reduces or eliminates your business rates bill depending on your property’s rateable value.
| Rateable Value (2025/26) | Relief Percentage |
|---|---|
| £12,000 or less | 100% (no rates payable) |
| £12,001 – £15,000 | Tapered relief from 100% to 0% |
| Over £15,000 | No relief available |
Example: A small retail shop with a rateable value of £13,000 may receive a partial discount under SBRR.
Tip: Review your property’s rateable value through the Valuation Office Agency (VOA) website, and consider an appeal if it seems inaccurate.

Research and development (R&D) tax credits
If your business invests in creating new products, improving processes, or developing innovative technologies, you could qualify for Research and Development (R&D) tax relief. R&D tax relief is a valuable incentive for many UK SMEs.
Under the 2025/26 scheme:
- Small and medium-sized enterprises (SMEs) can claim up to 21.5% back on qualifying R&D expenditure.
- Costs that can qualify include staff wages, prototype materials, and subcontractor fees.
Examples of qualifying activities:
- Developing new software systems or digital tools
- Improving manufacturing efficiency or product design
- Solving technical or scientific challenges
Tip: Keep detailed project documentation and expenditure records — HMRC often requests supporting evidence.
Employment and pension-related reliefs
Hiring employees or contributing to workplace pensions offers further tax benefits. Businesses can claim relief on several employment-related expenses and allowances.
| Relief Type | Description | Potential Benefit |
|---|---|---|
| Employment Allowance | Reduces employer NI contributions | Up to £5,000 per year |
| Pension Contributions | Deductible as a business expense | Lowers taxable profit |
| Apprenticeship Levy Credit | For companies training apprentices | Helps reduce training costs |
| Cycle to Work Scheme | Encourages green commuting | Tax-free benefit for employees |
Expert Tip: Combining salary optimisation with the Employment Allowance can significantly reduce your company’s annual tax burden.
Other tax reliefs worth considering
Beyond the main schemes, several niche reliefs can benefit specific industries or circumstances.
Additional reliefs include:
- Business rates relief for empty properties – partial exemption for unoccupied premises.
- EIS (Enterprise Investment Scheme) – tax relief for investors backing your business.
- Creative industry reliefs – available for film, animation, and gaming companies.
- Patent Box relief – reduces corporation tax on profits from patented inventions.
- Environmental and energy efficiency incentives – available to businesses investing in greener equipment or technology.
| Relief Category | Typical Sector | Tax Saving Potential |
|---|---|---|
| Creative Industry Relief | Film, TV, gaming | Up to 25% on qualifying production costs |
| EIS & SEIS | Startups, early-stage companies | 30–50% investor income tax relief |
| Patent Box | Technology & manufacturing | 10% corporation tax on qualifying profits |
