VAT vs Corporation Tax | What’s the Difference?

When you run a limited company in the UK, it comes with a lot of responsibilities, and paying taxes is at the top of the list. Many business owners still struggle to understand VAT vs Corporation Tax, and this confusion often leads to costly errors and compliance issues.

Understanding the difference is not just helpful; it is critical for protecting your profits and staying on the right side of HMRC. Knowing how these two taxes work will help you make informed financial decisions and prevent unexpected costs, whether you are just starting or scaling your business.

This guide clearly explains what VAT vs Corporation Tax are, how they differ, and how much you really need to pay.

What is Value Added Tax (VAT)?

It is important to understand the definition of VAT when comparing VAT vs Corporation Tax. VAT is a consumption tax imposed on most products and services in the United Kingdom. VAT is charged at each stage of the production and distribution process, typically at a standard rate of 20%. Moreover, it is ultimately paid by the final consumer.

What is the VAT Threshold?

As of 1 April 2024 and continuing into the 2026/27 tax year, if your taxable turnover exceeds £90,000 in a rolling 12-month period, you are required to register for VAT. You must register within 30 days of the end of the month in which you went over this threshold, or if you expect to exceed it in the next 30 days.

Once VAT-registered, you must ensure you meet your responsibilities. Businesses must charge VAT on their sales, known as output VAT and pay VAT on most of their purchases, known as input VAT. VAT-registered businesses function as collectors on behalf of HMRC, charging VAT to customers and remitting it regularly.

The difference between output VAT and recoverable input VAT is the amount payable to HMRC. A refund may be necessary if the input VAT exceeds the output VAT. However, it is crucial to recognise that not all input VAT is recoverable, and care should be taken to ensure claims are valid.

What is the VAT Rate in the UK?

When comparing VAT and Corporation Tax, it is important to understand the applicable VAT rates to price your products and maintain compliance. The applicable UK VAT rates depend on the type of products or services being provided. Generally, these rates apply to the items listed in the table below.

VAT Rate	% of VAT	What Rate Applies To
Standard Rate	20%	Most goods and services
Reduced Rate	5%	Some goods and services, such as residential property conversions, children’s car seats, and home energy, etc
Zero Rate	0%	Zero-rated goods and services, such as most food and children’s clothing

VAT does not apply to all sales; certain transactions are either exempt from VAT or fall outside its scope. For instance, insurance, health care, postage stamps, and non-private education are exempt. In the UK, VAT does not apply to statutory fees, services, and goods purchased and used outside the United Kingdom. Additionally, donations to charities are not subject to UK VAT.

What is Corporation Tax for Limited Companies in the UK?

In the discussion of VAT vs Corporation Tax, Corporation Tax is a tax that your limited company pays on the taxable profits it generates during a specific “accounting period.” Typically, an accounting period is 12 months long, and usually aligns with your financial year; however, it may be different in the year you set up your company.

For corporation tax purposes, profit is defined as the income that your company generated:

• Trading (or “doing business”) consists of income generated from selling goods and services.
• Investing consists of income from investments, such as rental income and interest on bank accounts
• Selling assets for a price higher than the original purchase price is also called chargeable gains.

How Much is Corporation Tax?

The “main rate” of corporation tax is 25% for profits exceeding £250,000. Additionally, there is a ‘small profits rate’ of 19% for profits of £50,000 or less. To effectively reduce your corporation tax from the 25% main rate, you may claim ‘marginal relief’ if your profits fall within the range of £50,000 to £250,000.

Key Difference: VAT vs Corporation Tax

To fully understand VAT vs Corporation Tax is that both are essential UK business taxes, as both operate in entirely different ways. One is linked to business sales, while the other is linked to your profits. It is beneficial to be aware of these distinctions to effectively manage your finances, maintain compliance with HMRC, and prevent costly tax errors.

Do I Pay Corporation Tax and VAT?

When it comes to VAT vs Corporation Tax, many business owners are unsure whether they are obligated to pay both. In short, the answer is yes, most limited companies in the United Kingdom are subject to both taxes; however, they are applied under different circumstances.

Corporation Tax must be paid by your company if it generates profits, as it is charged on your business earnings after expenses. Conversely, VAT registration is compulsory only if your taxable turnover surpasses the current threshold of £90,000. It becomes more likely that you will be required to oversee both VAT and Corporation Tax obligations as your business expands.

Can You Claim VAT Back On Corporation Tax?

When learning VAT vs Corporation Tax, it is important to clear up one common misconception: you can’t claim VAT back on Corporation Tax. This is because the two taxes are fundamentally distinct and operate differently.

VAT is reclaimable on eligible business expenses where VAT has been paid on purchases. Corporation tax is calculated based on your company’s net profit after deducting allowable expenses. Although the two cannot be linked directly, reclaiming VAT can reduce overall business expenses, potentially improving your taxable profit position.
