Does a Limited Company have to be VAT Registered in the UK?

In the UK, whether a limited company must register for Value Added Tax (VAT) is a critical question for new and existing business owners alike. The rules set by HMRC dictate specific circumstances under which VAT registration is mandatory, as well as options for voluntary registration. Here, we will explore these regulations to provide a comprehensive answer tailored for a UK audience.

What is VAT?

VAT is a tax applied on the sale of goods and services within the UK. As a consumption tax, the end consumer ultimately bears the cost. Businesses collect and account for the tax on behalf of HMRC. VAT registration involves a company charging VAT on its sales (output tax) and being able to reclaim VAT on its purchases (input tax).

Mandatory VAT Registration

Revenue Thresholds

A limited company must register for VAT if its taxable turnover exceeds the VAT threshold, which currently stands at £90,000 over a rolling 12-month period. This threshold is periodically reviewed and may change, so it’s important for businesses to stay updated.

Calculating Turnover for VAT

Taxable turnover refers to the total of everything sold that is not VAT exempt. This includes standard, reduced rate, or zero-rated sales. It’s crucial for companies to monitor their turnover and register for VAT within 30 days of their sales exceeding the threshold.

Other Conditions for Mandatory Registration

A limited company must also register for VAT if:

  • It expects its taxable turnover to exceed £90,000 within the next 30-day period alone.

  • It takes over another VAT-registered business as a going concern.

Voluntary VAT Registration

Companies with a taxable turnover below the threshold may choose to register for VAT voluntarily. Opting for voluntary registration can be strategically beneficial for several reasons:

Reclaiming VAT on Supplies: If you are VAT registered, you can reclaim the VAT paid on business-related purchases and expenses, which can be particularly advantageous for startups incurring initial costs.

Business Credibility: Being VAT registered can enhance a business’s profile and credibility, showing that the company is established and operates over the threshold.

Dealing with Other VAT Registered Companies: Some businesses prefer to deal only with VAT-registered companies, to ensure they can reclaim VAT on their purchases.

The Implications of VAT Registration


  • Potential to reclaim VAT paid on business expenses.

  • Enhanced business perception among clients and suppliers.

  • Ability to deal with other VAT-registered businesses, which might be crucial depending on the industry.


  • Additional administrative work to comply with VAT regulations.

  • Mandatory to charge VAT on applicable goods and services, which might affect pricing competitiveness.


Once registered, a company must charge VAT on all eligible goods and services, file regular VAT returns—usually quarterly—and keep accurate records. It’s important to comply with all HMRC regulations to avoid penalties.


If a company’s taxable turnover falls below the deregistration threshold, which is currently set at £88,000, it may choose to deregister from VAT. However, all the implications and potential future turnover must be considered before making such a decision.


In summary, a limited company in the UK must register for VAT if its taxable turnover exceeds £90,000 over any 12 month period, or if it expects to exceed that threshold rapidly. Companies can also choose to register voluntarily for strategic benefits. Managing VAT involves careful consideration of the benefits against the administrative responsibilities it brings.
