Tell HMRC when you change company name and address

When a company changes its address, it becomes imperative to inform about the change to vital authorities and agencies related to the business. The two prime authorities are: HM Revenue and Customs (HMRC) and Companies House, and they need to be informed on time in order to avoid fines (which might be incurred). An individual must update the address with HMRC if he / she pays income tax through pay-as-you-earn (PAYE) and resides in the UK. Doing so will update the address for:

Once the change is updated, the concerned person will receive an email to either confirm the change of details or request for more information, for example, legal documents to support the change of address or name. If an individual is signing in for the first time, they will need:

  • a Government Gateway account: this is generated when an individual uses the HMRC online services.
  • a National Insurance number (a temporary reference number does not work).

HMRC change of address or name for business

Who all need to be notified (for business)

While changing the address or name many different authorities / suppliers and clients need to be informed about the change. All these may not specifically relate to the business but if is vital to keep each of them informed about the change:

Financial institutions

  • Pension providers
  • Banks – all banks where an individual has accounts
  • Credit card firms
  • Loans companies

Services providers

  • Accountants and tax advisers - We at dns accountants help our clients with this
  • Insurance providers, for example employers, PI etc.
  • Legal advisors, i.e. IR35 services, solicitors etc.
  • Professional associations and institutions.

Customers and suppliers

  • Employees – well informed newsletters should be circulated.
  • Clients and other agencies.
  • Telecommunication providers, i.e. mobile, network, security, broadband etc.
  • IT Infrastructure providers, i.e. data centres, IT hosting / backup services.

As accountants of the company, dns accountants must be informed about the change in address or name so that we can update HMRC, Companies House, and company records in the software

Companies House

Updating the new registered office address with Companies House can be done either by completing offline forms or by updating the new records online. dns accountants will hand this for the clients; however the information below explains the steps.

Registered office address – Online

By using WebFiling on the Companies House website and logging with the registered email address and security code, an individual can enter the company registration number and verification code to access the company’s details. In case an individual forgets the authentication code, please remember that a new code, if requested from Companies House, will be sent by post. Therefore, it is very important the keep the authentication / verification code safe and handy.Also, it is advisable to keep the accountant informed about the authentication code. Once an individual has logged in, he / she can complete the online form ‘Change of Registered Office Address – AD01’. It is imperative to keep in mind that the registered office address must be a physical location for the purpose of delivery or inspection of official documents. It cannot be only a PO Box number unless it forms a part of the full address.

Registered office address – Offline

The above stated form AD01 – Change of Registered Office Address can be downloaded from the website and then can be completed, signed and posted to Companies House.

Company officer’s address


In a similar way, the records for the directors and company secretary can be updated using the WebFiling service online. Here two forms need to be updated: Form CH01 – Change of Director’s details and Form CH03 – Change of secretary’s details. The address for directors must be their standard residential address; however this won’t be evident on the public record.


Similarly, both forms CH01 and CH03 can be downloaded from the website. These forms should have all the latest information and must be sent to Companies House.


With there being multiple departments at HMRC, it becomes a little difficult and challenging to update the records at HMRC. This means that each taxation department needs to be informed separately and the options vary for each department. For example; for value added tax (VAT) one of the easiest ways to notify HMRC about the change of address is by using form VAT 484. Once records are updated with the department, an individual will receive a new VAT certificate.

  • For Corporation Tax, an individual updates the registered office address at Companies House; the same information will be passed onto HMRC automatically. No additional action is required to notify HMRC.
  • For PAYE (Employers), dns accountants will help update the PAYE records with HMRC online
  • For self-assessment, (which is related to an individual while VAT and Corporation tax are related to a company), HMRC roll out the changes to various departments including:

Other updates
