How to create a Land Transaction Tax online account
To file Land Transaction Tax online in Wales, you first need a user account. Although creating an account completes the initial stage, it does not by itself give you access, because your organisation’s online administrator must activate it before you can use the service. Activation is required.
What this rule is about
This describes an official online-service process rather than a tax rule. It helps the service check your email address and connect you to the right organisation before you use the Land Transaction Tax system.
Do not guess the organisation number. Your online administrator holds it.
What the official source says
The official source sets out the account-creation steps in order, starting with checking your email, continuing after Microsoft accepts the code with creating account details, and ending when you ask your administrator to give you access. That sequence matters.
- Enter your email address and select “Send verification code”.
- Look for a verification code sent by Microsoft.
- Use the code within 10 minutes.
- Check your junk or spam folder if the message does not arrive straight away.
- Contact the service if you still have not received it.
- Enter the code and select “Verify code”.
- Choose a password, confirm it and select “Create”.
- Enter your name when the next screen asks for it.
- Enter the organisation registration number from your online administrator.
- Tell that administrator once the account has been created.
What this means in practice
Have the details ready before you begin. Because the email step has a time limit, choose an inbox you can open immediately before starting the process, then use the code within 10 minutes once it arrives. Do this first.
Your account is only one part of the process. The administrator then needs to activate it. Until that happens, do not assume you can use the online service.
- Use an email inbox that you can check immediately.
- Check spam or junk before asking for help.
- Ask the administrator for the registration number before starting.
- Tell the administrator promptly when you finish creating the account.
How to analyse it
If the process stops, first check whether the verification email arrived, whether it went to junk or spam, and whether its code remains within the stated 10-minute window. Start there. Then follow the steps in the same order.
- Can you access the email address entered?
- Has the Microsoft message gone to junk or spam?
- Was the code entered within 10 minutes?
- Do you have the correct organisation registration number?
- Has the online administrator been told to activate the account?
Example
Sam enters an email address and receives a Microsoft code. Sam enters it eight minutes later, creates and confirms a password, then adds a name and the organisation number supplied by the administrator. Sam has created the account, but still needs to tell the administrator to activate it before Sam can use the online service. Activation is separate.
Why this can be difficult in practice
People may think the organisation number is a number they can find or make up. The official source says to get it from the online administrator. The wrong number could stop the service from linking the account correctly.
Another common problem is waiting too long to use the email code. The source gives a 10-minute limit. Because the source does not explain what happens after that limit, check the current service instructions if the code is no longer within the stated window. Check the instructions.
- Creating an account is not the same as being activated.
- The verification message may arrive in a junk or spam folder.
- The source does not give password rules or a code-expiry solution.
Key takeaways
- Use the Microsoft verification code within 10 minutes.
- Get the organisation registration number from the online administrator.
- Tell the administrator to activate your new account.
