There are two ways to ensure your account does not become dormant:
Carry out a financial transaction within 15 years. This can be a withdrawal, a lodgement or a reinvestment of a product that has matured. In order to carry out a financial transaction you may be required to provide up to date proof of identity and address documents.
Respond to the letter State Savings sends to you in the 15th year to inform you that your account may be marked dormant if we don't hear from you.
