I have not read much into the capital return and am no tax accountant. However I would assume by the nature of a dividend, that would relate to earnings and the posibility of franking credits attached (ie tax already paid by the company).As for a capital return, its a capital return and not associated with actual earnings from the course of business so therefore there will be no franking credit associated. In addition the capital return may have associated cap gains and hence the ato needs to review whether the capital return of 18 cents is reasonable and no further tax implications.happy to stand corrected.
