[vc_row][vc_column][vc_column_text]Corporation tax is an essential consideration for businesses in the UK, particularly limited companies. Whether you are running a small business or managing a larger enterprise, understanding how corporation tax works, how it is calculated, and how to reduce your tax bill can help you stay compliant and optimise your financial strategy. This guide explains the key points about corporation tax in the UK, including who is liable to pay it, the rates that apply, and how to ensure you meet the deadlines.
What is Corporation Tax?
Corporation tax is the tax that limited companies in the UK must pay on their profits. It is a significant source of revenue for the UK government and helps fund public services.
The amount of corporation tax a company owes is determined by its taxable profits, which are the profits earned after deducting allowable business expenses from total earnings. These expenses might include things like wages, rent, raw materials, and other costs associated with running the business.
If a company does not make a profit during its accounting period, it will not owe any corporation tax. However, it must still file a company tax return with HMRC, even if no tax is due.
Who Pays Corporation Tax?
Corporation tax is payable by any UK-based limited company that generates profit. In addition to limited companies, other business entities may also be required to pay corporation tax on any profits they make. This includes:
- Clubs and societies, such as sports clubs or community groups
- Foreign companies that operate a branch or office in the UK
- Co-operatives
It is important to note that sole traders and partnerships do not pay corporation tax. Instead, these business types pay income tax on their earnings through self-assessment. A partnership is also not liable for corporation tax unless one of the partners is a limited company, or the partnership is no longer a profit-making entity, such as when it becomes a charity.
How Much is Corporation Tax in the UK?
The rate of corporation tax a business must pay depends on its profit level during its accounting period. For the financial year starting 1 April 2025, the rates are as follows:
- 19% for companies with profits under £50,000. This is known as the small profits rate.
- 25% for companies with profits over £250,000. This is the main rate for larger businesses.
- Marginal relief is available for companies with profits between £50,000 and £250,000. This reduces the 25% tax rate gradually as profits increase.
Businesses should be aware of these thresholds to understand the tax rate that will apply to them and to plan ahead for how much corporation tax will be due.
How is Corporation Tax Calculated?
To calculate corporation tax, businesses must follow a few essential steps. Here is a simple breakdown of the process:
Step 1: Calculating Taxable Profits
The first step in calculating corporation tax is to determine taxable profits. This is done by adding up all the profits a company has made in its accounting period, including profits from selling goods or services, as well as any profits from investments or gains from selling assets. Then, allowable business expenses are subtracted from this total. Allowable expenses include things like wages, rent, raw materials, and other day-to-day costs associated with running the business.
Step 2: Check for Allowances and Relief
Certain allowances and reliefs can help reduce the taxable profits of a business. These may include:
- Capital allowances for equipment or machinery
- Research and development tax credits for businesses involved in scientific or technological development
- Trading losses, which can be carried forward and offset against future profits
These allowances and reliefs can significantly reduce the tax bill, so it is essential to ensure that all eligible claims are made.
Step 3: Applying the Tax Rate
Once taxable profits and allowances are calculated, the applicable tax rate is applied. For businesses with profits under £50,000, the small profits rate of 19% is applied. For profits over £250,000, the 25% main rate is applied. If a business’s profits fall between these amounts, marginal relief will be applied to reduce the 25% tax rate gradually.
Step 4: Calculating the Amount Due
The final step is to apply the relevant tax rate to the taxable profits, taking into account any allowances and reliefs, to calculate the amount of corporation tax due. The calculation should be done carefully, and if in doubt, using a tax advisor or accountant can help ensure accuracy.
How to Register for Corporation Tax
Before a business can start paying corporation tax, it must register with HMRC. The registration process begins once the business has been registered with Companies House. After registration, HMRC will send the business a Unique Taxpayer Reference (UTR) number, which is required for the tax registration.
Businesses must complete the registration process within three months of starting any business activities. To register, you will need the following information:
- Your company’s registration number, which can be found on your certificate of incorporation
- The date your company became active
- Your company’s year-end date
Corporation Tax Deadlines
Corporation tax comes with a few key deadlines that businesses need to be aware of:
- File first accounts with Companies House: Within 21 months of registering the company
- File annual accounts with Companies House: 9 months after the end of your financial year
- Pay corporation tax: 9 months and 1 day after the end of your accounting period for corporation tax
- File a company tax return: 12 months after the end of your accounting period for corporation tax
It’s essential to meet these deadlines to avoid penalties and interest charges.
How to Pay Corporation Tax
Corporation tax payments can be made using several methods:
- Direct Debit
- Online banking
- Telephone payment
- Corporate credit card (note, personal credit cards cannot be used)
- Visiting the bank with a paying-in slip from HMRC
For companies with profits over £1.5 million, payments must be made in instalments. For smaller companies, the tax bill is due 9 months and 1 day after the end of the accounting period.
How to Reduce Your Corporation Tax Bill
No one wants to pay more tax than necessary, and there are several ways businesses can reduce their corporation tax bill:
- Claim allowable business expenses: Keep track of all expenses and ensure they are included in your tax return. These may include things like rent, utilities, and office supplies.
- Capital allowances: For high-value assets like machinery or equipment, capital allowances can be claimed to reduce taxable profits.
- Research and development tax credits: Available for companies involved in scientific or technological development.
- Other reliefs: Companies in creative industries or those reducing their carbon footprint may qualify for other tax reliefs.
What Are the Penalties for Late Filing?
Failing to meet corporation tax filing deadlines can result in penalties. The penalty system is tiered:
- £100 fine if the tax return is 1 day late
- £100 fine if the tax return is 3 months late
- 10% penalty added to the unpaid tax if the return is 6 months late
- Another 10% penalty added if the return is 12 months late
To avoid these penalties, ensure that all deadlines are met and filings are made on time.
Conclusion
Understanding corporation tax is essential for business owners. By tracking taxable profits, applying allowances and reliefs, and meeting the necessary deadlines, you can minimise your tax liability and stay compliant. With the right planning and a clear understanding of your responsibilities, you can optimise your tax strategy and focus on growing your business.
