Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what consideration has been given to adding (a) a company registration number field to the HMRC VAT number checker service and (b) a VAT registration number field to the Companies House public register, so that the two identifiers can be cross-referenced by members of the public, online marketplaces, and customs agents.

HM Revenue and Customs (HMRC) and Companies House (CH) are committed to preventing fraud and tax evasion by identifying and holding accountable corporate entities that attempt to evade their responsibilities and tax liabilities. The departments have strong relations, further strengthened by the Economic Crime and Corporate Transparency Act (2023) and have developed a collective Programme of activities to facilitate closer cooperation on company registrations and de-registrations, accounting and filing, and sharing risk intelligence and data.

There are no plans in place to add a Company Number field to the UK VAT Registration checker service, or a VAT Registration Number field to the Companies House online register. However, HMRC and CH will continue to work together to develop and implement further improvements to the way that businesses register as a company and register for corporation tax and VAT to reduce tax evasion and corporate fraud.
