Introduction

Running a business means mastering tax obligations to avoid penalties and maximise savings. In 2026, UK businesses face evolving rules on income tax, VAT, National Insurance, and deductions, influenced by global trends like renewable incentives and employee benefits.[1][5] Whether you're a sole trader, limited company, or partnership, understanding tax basics ensures financial health. This guide breaks it down step-by-step, with practical advice tailored for UK entrepreneurs.

Key Taxes Every UK Business Must Know

UK businesses pay several taxes based on structure. Here's a breakdown:

  • Income Tax and Corporation Tax: Sole traders and partnerships pay income tax on profits (20-45% rates). Limited companies pay Corporation Tax at 19-25%.[3]
  • National Insurance Contributions (NICs): Employers pay 13.8% on employee earnings above £9,100; self-employed pay Class 2/4 NICs at 6-9%.[7]
  • VAT: Register if turnover exceeds £90,000; charge 20% on most sales and reclaim input VAT.[2]
  • PAYE and Payroll Taxes: Deduct income tax and NICs from wages; file monthly or quarterly.[4]
  • Self-Employment Tax: Covers sole traders, akin to 15.3% in some systems, funding social security.[3]

Pro tip: Use accounting software for automated tracking to simplify compliance.[2]

2026 Tax Changes and Opportunities

Global shifts offer lessons for UK firms. While UK-specific rules apply (check HMRC for Budget updates), watch these trends:

  • Renewable Energy Incentives: Shorter-lived credits boost green investments; UK offers similar SEIS/EIS reliefs.[1]
  • Employee Deductions: New tips (£25,000 limit) and overtime (£12,500) breaks inspire UK perk planning like childcare credits.[1][3]
  • SALT-Style Deductions: Higher state tax limits abroad highlight UK property and expense reviews.[5]
  • QBI Equivalent: Permanent 20% pass-through relief; UK sole traders can leverage trading allowance (£1,000 tax-free).[5]
  • R&D Expensing: Immediate deductions for domestic research; align with UK R&D tax credits up to 27%.[3]

Top Deductions to Maximise Savings

Claim these to reduce taxable income:

  • Home Office: Square footage ratio of utilities/rent; log mileage at HMRC rate (45p/mile first 10,000).[4][6]
  • Vehicle and Travel: Actual costs or mileage; business trips fully deductible.[6]
  • Office Expenses: Rent, supplies, software subscriptions.[6]
  • Employee Benefits: Salaries, pensions, health insurance for self-employed.[6]
  • Marketing and Professional Fees: Ads, legal, accounting from firms like Cheshire Business Accountants.[6]
  • Startup Costs: Up to £1,000 relief; amortise rest.[6]

Set aside 25-35% of profits quarterly to avoid penalties.[3]

Business Tax Preparation Checklist for 2026
