Under the Superannuation (Unclaimed Money and Lost Members) Act 1999, superannuation funds must identify certain types of lost and former temporary resident accounts as unclaimed superannuation money and transfer amounts to the ATO every six months. Since 1 July 2013, any unclaimed superannuation money payments from the ATO to individuals includes interest, at a rate equivalent to the consumer price index, to preserve the value of these accounts. While the Treasury has policy responsibility, the ATO administers the program.
