Can two separate businesses be treated as one for VAT registration?

Yes, in some circumstances. HMRC can examine whether a business has been artificially separated to avoid VAT registration. Different names, bank accounts or legal entities do not settle the question, but genuinely independent businesses are not automatically combined.

These answers provide general information, not advice tailored to your circumstances. Rules can change and exceptions may apply — speak to the CASS team before making a tax, accounting or financial decision.

Look at how they operate

Consider the financial, economic and organisational links. Shared customers, staff, premises, equipment or control can be relevant, although no single feature decides every case.

A new name is not enough

Splitting activities between entities simply to keep each below the registration threshold can create a problem. Records and contracts should reflect how the businesses genuinely work.

Genuine separation needs assessment

Independent businesses can exist alongside each other. The facts matter, including who supplies the customer, bears the risk and manages each activity. Common ownership alone does not answer everything.

Ask before restructuring

Discuss the arrangement with CASS before changing ownership or billing. We can review the VAT questions and identify where specialist advice is appropriate.
