Subtract the amount at C from the amount at B. If the result is greater than zero, show the result at D. If the result is less than or equal to zero, show zero at D. See examples 9a and 9b.
The amount at D cannot be less than zero, that is, it cannot be a negative amount. This is because foreign income tax offsets and rebates and tax offsets shown at C cannot exceed the gross tax amount shown at B.
Any unused rebates and tax offsets shown at C will not be recorded by us to be applied in future years. Where it is possible to carry forward a credit, the fund is required to keep its own records if it is carrying the credits forward to a later date.
