2. Register your organisation to file Landfill Disposals Tax online

Use this service to register your organisation and online administrator to file Landfill Disposals Tax (LDT) online as a landfill site operator.

Before you start

You cannot register an organisation more than once, so first check if your organisation is already registered to file LDT online.

If you’re a parent or corporate group representing more than one organisation, contact us to request a group registration. We can arrange a separate registration for each company. Email

If you’re unsure whether an account already exists, please contact us.

You’ll need the following information:

  • your organisation’s name, address, and Companies House number
  • your Natural Resources Wales permit numbers
  • information about the sites you wish to register, for example site address
  • the name, postal address, email, and phone number for the person to act as your online account administrator
  • details of a key contact within your organisation

Email addresses should be an individual email address like ‘’ not a shared mailbox such as ‘info@’.

To complete registration

Your online administrator will receive your organisation registration number by encrypted email within 2 weeks.
