You do not need to perform any procedures. The tax agency’s system will automatically perform this conversion.

Case 2: Information has not matched, need to act immediately

This is the case you need to pay special attention. If there is any deviation between tax information and population data, your tax code will temporarily be put into a “update waiting” state on the system.

This means that you are required to carry out the procedures for adjusting tax registration information. Only after the information is updated accurately and confirming the success, your personal identification number is officially used instead of MST.

Case 3: Owning multiple tax codes, what to do?

New regulations for taxpayers for the first time and business households

For individual tax registration for the first time

The prerequisite is that you must accurately declare your full name, date of birth and personal identity.

Major change for business households

A landmark rule for households and individuals is not a separate MST for each business location anymore.
