ihre compliance

Indirect tax in the UK includes Value Added Tax (VAT), excise duties, and customs duties. The following guide provides a comprehensive overview of UK VAT compliance. Understanding the concept of tax compliance for VAT is crucial for businesses (particularly for the head of tax or tax technologist) to ensure it adheres within the tax laws, and to avoid potential penalties or complications. It serves as evidence that a business has met its obligations regarding VAT.  

Achieving full compliance involves a thorough review of a business's tax-related activities, including its reporting accuracy in adherence to applicable tax regulations. This evaluation ensures that the business has fulfilled its tax obligations and met all the necessary legal requirements. By obtaining this, businesses can present to various stakeholders, including tax authorities, clients, business partners, and financial institutions. It compliments the business's confidence in its ability to meet financial obligations and operate in a compliant manner.   

Why is Tax Compliance Important?

Tax compliance is required in all countries where a business trades and also when the business is seeking to expand its operations into new regions. Many organisations and institutions would consider this as a prerequisite for engaging in business activities or establishing partnerships. By obtaining and maintaining compliant status, businesses can demonstrate their commitment in adhering to regulatory tax procedures and increase their eligibility for various expansion opportunities.  

Continuous compliance is also important for the following reasons.

  1. Demonstrating a commitment to tax compliance is highly regarded by the tax authorities when it comes to businesses. This can help to build trust and credibility with customers, suppliers, and other stakeholders, and can also help to minimize the risk of penalties and enforcement action from HMRC in the UK. 
  2. Providing assurance to customers and suppliers that a business is compliant with all UK tax laws and regulations, and therefore operating in a transparent and ethical manner. This can be especially important for businesses that operate in international markets, as it demonstrates to foreign customers and suppliers that the business operates to the high standards of UK tax compliance.  

Who Requires UK Tax Compliance for VAT?

VAT compliance is typically required of businesses that are buying or selling goods or services in the UK, or that are importing or exporting goods to/from UK.

It is important to note that HMRC reserves the right to deny VAT registration or revoke a business’ VAT registration if it is found to be non-compliant with any regulations. 

How to Be Compliant When Filing VAT Returns

For staying compliant, businesses must file VAT returns on time and pay any VAT owed to HMRC on time. This means submitting a VAT return to HMRC on a regular basis, usually every three months, known as your ‘accounting period’. The usual deadline for submitting your VAT return and paying any outstanding VAT to HMRC is one month and seven days after the end of your VAT return period.  Even if you have no VAT to pay or reclaim, you must still submit a VAT Return if you are registered for VAT.  
It’s crucial to highlight that HMRC uses a range of enforcement measures to ensure that businesses comply with VAT laws and regulations, including fines and penalties for late payment or inaccurate VAT return submissions.  

Should Businesses Pay Any VAT That is Owed?  

In addition to filing VAT returns, businesses must also pay any net VAT owed to HMRC in a timely manner. The amount of VAT owed will depend on the value of goods and services sold, as well as any VAT claimed on business inputs and expenses.  
Precisely calculating the owed VAT amount is of utmost importance, paying it on time will avoid penalties and any enforcement action from HMRC. If a business is having difficulty paying VAT owed, they should contact HMRC to discuss their options.  

Why Is It Imperative to Keep Accurate VAT Records?

Businesses must also keep accurate records of all VAT relevant transactions. This includes invoices, receipts, and other documentation that provides evidence of the value of goods and services sold and purchased, as well as any VAT charged or reclaimed.  
Accurate records are essential for calculating the amount of VAT owed and for proving compliant processes with indirect tax laws and regulations in the event of an audit by HMRC. Businesses and individuals should keep records for a minimum of six years, as HMRC has the right to request these records at any time during this period.  
Once a business has fulfilled all requirements for indirect tax compliance, including VAT return filing, payment of owed VAT and accurate records, HMRC will then review the tax report. Even if the business is found to be compliant with all indirect tax laws and regulations, HMRC may require additional information or clarification.  


Tax compliance for VAT is a vital step within the tax process for businesses operating in the UK. This provides assurance to customers and suppliers that a business is fully compliant with UK tax laws and regulations.  
Including the following:

  1. Filing accurate VAT returns  
  2. FIling VAT returns on time  
  3. Keeping accurate VAT records  
  4. Timely paying any VAT this is owed  

By demonstrating a commitment to UK VAT compliance, businesses and individuals can build trust and credibility with customers, suppliers, and other stakeholders. It can also help to minimise the risk of penalties and enforcement actions from HMRC. Furthermore, it serves as a clear indication of the company's obligation to ethical and responsible financial practices. 

Ensuring VAT compliance not only protects the business from potential penalties and legal consequences but also contributes to the overall stability and growth of the UK economy. Therefore, it’s crucial for businesses to prioritise their accurate VAT calculations to ensure full compliance for the tax authorities.
