A Guide to Corporation Tax for your Company

Understanding corporation tax is essential for any company owner or manager. Paying the right amount of tax on your company’s profits ensures compliance with the law and helps avoid costly penalties. This guide explains the basics of corporation tax, how it works, and practical steps your company can take to manage it effectively.

What Is Corporation Tax?

Corporation tax is a tax on the profits made by companies and other organisations. It applies to limited companies, some clubs, societies, associations, and other organisations. The tax is charged on the company’s taxable profits, which include trading profits, investment income, and capital gains.

The rate of corporation tax varies depending on the country and sometimes the size of the company. For example, in the UK, the main rate is currently 25% for companies with profits over £250,000, while smaller companies with profits below £50,000 pay a lower rate of 19%. Companies with profits between these thresholds pay a tapered rate.

How Corporation Tax Works

Corporation tax is calculated based on your company’s accounting period, which usually aligns with your financial year. The process involves:

• Calculating taxable profits: Start with your company’s total profits, then adjust for allowable expenses, reliefs, and any non-taxable income.

• Applying the tax rate: Multiply the taxable profits by the corporation tax rate.

• Filing a tax return: Submit a corporation tax return to the tax authority, detailing your profits and tax calculation.

• Paying the tax: Pay the tax due by the deadline, which is usually nine months and one day after the end of your accounting period.

  
  

Failing to file returns or pay tax on time can lead to penalties and interest charges.

Allowable Expenses and Reliefs

Your company can reduce its taxable profits by deducting allowable expenses. These are costs incurred wholly and exclusively for running the business. Common allowable expenses include:

• Rent and utilities for business premises

• Salaries and wages of employees

• Business travel and subsistence costs

• Office supplies and equipment

• Marketing and advertising costs

  
  

Some expenses are not allowable, such as client entertainment or personal expenses.

There are also reliefs available that can reduce your corporation tax bill. For example, research and development (R&D) relief allows companies investing in innovation to claim extra deductions or tax credits. Capital allowances let you claim tax relief on certain purchases like machinery or vehicles.

Practical Tips for Managing Corporation Tax

Managing corporation tax efficiently can save your company money and reduce stress. Here are some practical tips:

• Keep accurate records: Maintain detailed and organised financial records throughout the year. This makes it easier to calculate profits and claim all allowable expenses.

• Plan your accounting period: Choose an accounting period that suits your business cycle. This can help with cash flow planning and tax payments.

• Use tax software or professionals: Consider using accounting software designed for corporation tax or hiring an accountant. They can help ensure your tax return is accurate and complete.

• Claim all reliefs: Research available reliefs and ensure you claim those relevant to your business activities.

• Prepare for payments: Set aside funds regularly to cover your corporation tax bill. This avoids surprises when the payment deadline arrives.

  
  

Examples of Corporation Tax in Action

Imagine a small company with £100,000 in profits. If the corporation tax rate is 19%, the company will owe £19,000 in tax. However, if the company invested £10,000 in qualifying R&D, it might claim additional relief, reducing its taxable profits and lowering the tax bill.

A larger company with £500,000 in profits at a 25% tax rate would owe £125,000. By claiming capital allowances on new equipment purchases, the company could reduce its taxable profits and save thousands in tax.

What Happens If You Don’t Pay Corporation Tax?

Not paying corporation tax on time can lead to serious consequences. The tax authority may charge interest on late payments and impose penalties. Repeated failures can result in legal action or restrictions on your company’s activities.

It is important to communicate with the tax authority if you face difficulties paying your tax bill. They may offer payment plans or other support options.
