How to sign in to LTT online with a verification code
To sign in to LTT online, enter your email address and password first. The service then emails you a one-time code. Enter that code to finish signing in.
What this rule is about
LTT online, which the Welsh Revenue Authority provides for Land Transaction Tax, requires anyone signing in to prove they can access the email account linked to the service. The code provides that extra check.
This is not a tax calculation or a stamp duty rule. It is only a sign-in step.
What the official source says
The Welsh Revenue Authority tells you to begin at its File LTT online page, where the service validates your sign-in details before it emails a one-time verification code. The email contains the code.
- Go to the File LTT online service.
- Enter your email address and password.
- Wait for the service to validate those details.
- Look for an email from Microsoft, sent for the Welsh Revenue Authority.
- Enter the code on the sign-in page and select “verify code”.
- If the code is correct, select “continue” when the service prompts you.
When the service issues a code, it remains valid for 10 minutes. You need a fresh code each time you sign in. You also need one if you restart your browser.
What this means in practice
Your password alone does not complete the sign-in. You must be able to receive and use the emailed code during the same sign-in process.
- Use the email address connected to your LTT online account.
- Check for a Microsoft email sent on behalf of the Welsh Revenue Authority.
- Enter the code before its 10-minute validity period ends.
- Select “verify code”, then “continue” if the code is accepted.
How to analyse it
If sign-in does not reach the account screen after you enter your email address and password, the service validates them, and you use the emailed code, work through the steps in order. Check both parts.
- Are you on the File LTT online service?
- Have you entered the email address and password?
- Has the service validated those details?
- Have you checked for the verification-code email?
- Have you entered that code and selected “verify code”?
- Did you then select “continue” after the confirmation message?
Example
Sam opens LTT online and enters an email address and password. Once the service validates them, Sam receives a code in an email from Microsoft on behalf of the Welsh Revenue Authority. Sam enters it within 10 minutes, selects “verify code”, then selects “continue”. Sam has signed in. If Sam later restarts the browser, Sam needs a new code.
Why this can be difficult in practice
The short time limit disrupts sign-in. You cannot treat a code as permanent or reuse it for a later sign-in.
- Do not expect a previous code to work after signing in again.
- Do not expect a previous code to work after restarting the browser.
- The supplied guidance does not say what to do if the email is delayed or the code has expired.
Key takeaways
- Sign in with your email address and password first.
- Use the emailed code within 10 minutes of issue.
- Get a new code for every sign-in or browser restart.
