Guides

Corporation Tax is a tax levied on the profits of limited companies and certain other organisations in the United Kingdom. If you’re running a business or involved in corporate activities, understanding UK Corporation Tax is crucial. In this simple guide, we’ll explain the basics of Corporation Tax and highlight key points you should know.

  1. What is Corporation Tax? Corporation Tax is a tax imposed on the taxable profits of companies, including limited companies, foreign companies with UK branches, and other corporate entities. It applies to trading profits, investment income, and capital gains generated by these organisations.
  2. Determining Taxable Profits: To calculate your Corporation Tax liability, you need to determine your taxable profits. Taxable profits are generally based on the company’s accounting profits adjusted for certain tax rules and allowances. Key factors to consider include:
  • Revenue: Deduct allowable expenses from your business revenue to arrive at your trading profits.
  • Capital Gains: Report any capital gains made from selling assets, such as property or investments.
  • Tax Adjustments: Apply specific rules and allowances to adjust profits, such as capital allowances for eligible assets and deductions for certain business expenses.
  1. Corporation Tax Rates: The standard Corporation Tax rate applies to most companies in the UK. However, rates may vary based on the amount of taxable profits and the size of your company. As of the 2021-2022 tax year, the rates are as follows:
  • Small Profits Rate: 19% for companies with taxable profits up to £50,000.
  • Main Rate: 25% for companies with taxable profits above £250,000.
  • Special Rate: 20% for unit trusts and open-ended, investment companies.
  • Companies with profits between £50,000 and £250,000 will pay tax at main rate, reduced by a marginal relief. This provides a gradual increase in the effective Corporation Tax rate. It’s important to regularly check the latest rates, as they can be subject to change.
  1. Filing and Payment Deadlines: Companies are required to file a Corporation Tax return with HM Revenue and Customs (HMRC) within 12 months after the end of their accounting period. The tax liability must also be paid within nine months and one day after the end of the accounting period. It’s crucial to comply with these deadlines to avoid penalties and interest charges.
  2. Allowable Deductions and Reliefs: Corporation Tax allows for deductions and reliefs that can reduce your taxable profits. Common deductions and reliefs include:
  • Capital Allowances: Claim allowances for qualifying assets, such as equipment, machinery, and vehicles used in your business.
  • Research and Development (R&D) Relief: If your company invests in R&D activities, you may be eligible for enhanced relief, reducing your Corporation Tax liability.
  • Loss Relief: Carry forward losses from previous years to offset against current or future profits, reducing your tax liability.
  • Patent Box: If your company earns income from patented inventions, you may qualify for a reduced Corporation Tax rate of 10% on those profits.
  1. Compliance and Record-Keeping: To meet your Corporation Tax obligations, it’s essential to maintain accurate financial records and comply with reporting requirements. Keep detailed records of your income, expenses, assets, and transactions. Additionally, ensure that you follow the guidelines for record retention and maintain a complete and organised financial trail.
  2. Seeking Professional Advice: Corporation Tax rules can be complex, especially when dealing with specific circumstances or navigating different allowances and reliefs. It’s recommended to consult a qualified accountant or tax advisor who can provide tailored advice and ensure you meet your obligations while optimising your tax position.

Understanding UK Corporation Tax is vital for businesses and corporate entities. By grasping the basics of this tax, including taxable profits, rates, deductions, and deadlines, you can fulfill your obligations and make informed decisions to manage your tax liabilities efficiently. Don’t hesitate to consult a professional advisor to ensure you keep on top of your legal requirements.
