Inquiring about relevant information shows that the tax bureau called to say that you have to pay taxes, and the number is wrong. You can ask the other party for more information to prove your identity. You can ask the other party's tax authority, name and employee number during the call. If they can provide the above information, and you confirm that they are the staff of the tax bureau, then you need to know in detail what they are saying and why, and determine whether your tax situation really requires tax payment.
