What Should Entrepreneurs Know About London Business Taxes?
Starting and running a business in London offers huge opportunities but understanding the UK tax system is critical for long-term success. From Corporation Tax to VAT and Income Tax, entrepreneurs must navigate multiple obligations while also taking advantage of reliefs and allowances.
This guide breaks down everything you need to know about London business taxes in 2026, helping you stay compliant and financially efficient.
Understanding the UK Business Tax Landscape
London businesses operate under the wider UK tax system, meaning taxes are governed nationally rather than locally. However, costs like business rates and operational expenses in London can significantly impact your overall tax burden.
Key Taxes Entrepreneurs Must Know
| Tax Type | Who Pays It | Key Rate (2026) |
| Corporation Tax | Limited companies | 19%–25% |
| Income Tax | Sole traders | 20%–45% |
| VAT | VAT-registered businesses | 20% standard |
| National Insurance | Employers & employees | Variable |
| Business Rates | Property occupiers | Based on value |
Corporation Tax: The Core Business Tax
If you run a limited company, Corporation Tax is your primary obligation.
Current Corporation Tax Rates
- 19% for profits under £50,000
- 25% for profits above £250,000
- Marginal relief applies between these thresholds
This tiered system means small businesses benefit from lower rates, while larger companies pay more.
What Counts as Taxable Profit?
Your taxable profit includes:
- Trading profits
- Investment income
- Capital gains
Expenses like salaries, rent, and equipment can be deducted to reduce your tax liability.
Income Tax for Sole Traders
If you operate as a sole trader or freelancer, you’ll pay Income Tax on profits instead of Corporation Tax.
2026 Income Tax Bands
| Income Range | Tax Rate |
| Up to £12,570 | 0% |
| £12,571–£50,270 | 20% |
| £50,271–£125,140 | 40% |
| Over £125,140 | 45% |
The £12,570 personal allowance means you don’t pay tax on income below this threshold .
VAT: When Does It Apply?
Value Added Tax (VAT) is another major consideration.
When You Must Register
You must register for VAT if:
- Your turnover exceeds £90,000 (threshold subject to updates)
- You expect to exceed the threshold soon
VAT Basics
- Standard rate: 20%
- Charged on most goods and services

Proper VAT management improves cash flow and prevents penalties.

Key Points for 2026
- Rates depend on your property’s rateable value

London businesses often face higher rates due to premium property values, so budgeting is essential.
National Insurance Contributions (NICs)
Entrepreneurs must also consider National Insurance:
Types of NICs
- Class 2 & 4: Paid by self-employed individuals
- Employer NICs: Paid when hiring staff
Recent changes have increased employer costs, making workforce planning more important than ever.
Capital Gains Tax and Business Sales
If you sell business assets or shares, Capital Gains Tax (CGT) applies.
2026 Updates
- Business asset disposal relief now taxed at 18%
- Annual CGT allowance reduced to £3,000
This makes exit planning more important for entrepreneurs.
Tax Reliefs and Allowances You Should Use

Key Reliefs
- Annual Investment Allowance (AIA)
- R&D Tax Credits
- Capital Allowances
- Business Asset Disposal Relief
From 2026, a 40% first-year allowance on certain assets can help reduce taxable profits .
