Simple steps to prevent tax identity theft
Always keep your National Insurance number, UTR, and Government Gateway details private. These identifiers should be treated with the same caution as your bank details.
Create strong, unique passwords for your tax accounts. A password manager can help you maintain different secure passwords for various services without needing to remember them all.
Enable two-factor authentication on your Government Gateway account. This extra security step makes it significantly harder for fraudsters to access your account, even with your password.
Be extremely cautious about sharing personal details on social media. Information like your date of birth or address history can help criminals piece together enough data to steal your identity.
Check your tax account regularly for any unexpected changes or submissions. I once spotted an unfamiliar address change on my account that alerted me to an attempted fraud before any damage was done. Understanding the penalty for filing self-assessment late but paid on time is also important if fraudsters attempt to manipulate your filing records.
