Revocation must be submitted only with main return being lodged.

There is no standalone option to revoke an IEE. The standalone IEE form is available for making an election only. A revocation must be included with the relevant main tax return.
This is an ATO lodgment requirement, so LodgeiT cannot provide a standalone IEE revocation option or bypass this requirement.
Tip: If the main tax return has already been lodged, the IEE revocation schedule generally cannot be added by amending the lodged return.
