(a) an assessment is made under the Superannuation Contributions Tax (Assessment and Collection) Act 1997 in respect of a superannuation provider's liability to pay superannuation contributions surcharge in respect of a person who has failed to provide a tax file number; and
(b) the superannuation provider has paid the assessed amount of the surcharge in respect of the person; and
(c) the assessment is amended under section 18 of the Superannuation Contributions Tax (Assessment and Collection) Act 1997 after the person provides a tax file number reducing the liability of the provider to pay surcharge;
interest is payable by the Commissioner to the superannuation provider in accordance with this Part on the amount by which the surcharge payable by the provider under the amended assessment is less than the surcharge that was paid by the provider under the assessment that was amended.
