VAT Registration for Multiple Businesses: Understanding the Requirements.
When you expand your business or start a new one, VAT (Value Added Tax) becomes a key consideration. If you’re already VAT-registered for one business and start another, you might wonder if the new company needs to register for VAT separately. Several factors influence this, especially if both businesses have the same ownership or offer similar services.
In this blog, we’ll explain the VAT registration rules for multiple businesses and help you determine whether you need to register your second business for VAT.
Understanding the VAT Registration Threshold
In the UK, any business that exceeds £90,000 in taxable turnover over a 12-month period must register for VAT with HMRC. Once your business hits this threshold, you must register for VAT. Businesses below this amount can choose to register voluntarily, which can bring benefits like reclaiming VAT on purchases.
The key question is whether the threshold applies separately to each business or if HMRC will consider the businesses as one for VAT purposes.
What Makes a Business Separate?
If you open a second company that is a separate legal entity, VAT rules generally treat the two businesses independently. If the second business’s turnover is below £90,000, it doesn’t need to register for VAT right away. You can wait until its turnover approaches the threshold.
However, HMRC requires clear distinctions between the businesses. Here are some factors that show they are separate:
- Each business must have separate bank accounts.
- They should operate from different locations.
- The businesses should employ different staff.
- Keep financial records independent for each company.
When your businesses maintain these distinctions, HMRC is more likely to treat them as independent for VAT purposes.
Avoiding the Risk of Artificial Separation
HMRC monitors for what is known as “artificial separation.” This occurs when business owners split what is essentially one business into two or more to avoid VAT registration. If HMRC suspects artificial separation, they will combine the businesses’ turnovers. If the total turnover exceeds £90,000, both businesses will need to register for VAT, even if each business individually stays below the threshold.
HMRC may view your businesses as artificially separated if:
- Both businesses share common ownership and control.
- They engage in similar or identical business activities.
- They share resources like staff, premises, or customers.
If HMRC determines that your businesses aren’t truly separate, they will combine the turnovers and require both companies to register for VAT.
What If My Second Company’s Turnover Is Below £90,000?
If your second company’s turnover is below £90,000 and it operates independently, you don’t need to register for VAT right away. You can wait until the turnover approaches the threshold.
However, you should monitor the turnover on a rolling 12-month basis. Even if the company hasn’t reached £90,000 within a single calendar year, it may still reach the threshold over any 12 months. At that point, you’ll need to register for VAT within 30 days.
Voluntary VAT Registration: Is It a Good Idea?
Even if the second business doesn’t meet the VAT threshold, you may want to consider voluntary VAT registration. Voluntarily registering allows you to charge VAT on sales and reclaim VAT on business expenses. This option can be beneficial if:
- You expect to incur significant VAT on business purchases.
- Your customers are VAT-registered and can reclaim the VAT you charge.
- You want to present your business as more established, as being VAT-registered can add credibility, especially in B2B markets.
However, if your customers are consumers or small businesses that can’t reclaim VAT, charging VAT may make your products or services less attractive due to higher costs.
VAT Grouping: A Possible Solution
If both businesses are limited companies under common control, you could form a VAT group. VAT grouping allows you to account for VAT as a single entity. In a VAT group, you only charge VAT on sales to external customers, and transactions between the grouped companies are not subject to VAT.
VAT grouping can simplify administration, but you must follow specific rules.
Conclusion: Stay Compliant and Avoid Pitfalls
If you’ve opened a second company under the same ownership, you don’t need to register for VAT unless the turnover exceeds £90,000. However, make sure that the two businesses remain truly separate to avoid HMRC combining their turnovers. Regularly monitor your turnover since the VAT threshold is based on a rolling 12-month period.
If you’re uncertain about how VAT rules apply to your businesses, consult a tax advisor. With proper planning, you can ensure compliance with HMRC and avoid unexpected VAT liabilities.
