The Tax Base of a Liability Must Be Calculated as the Liability's

The tax base of a liability must be calculated as the liability's carrying amount as at the reporting date,less any future deductible amounts and plus any future assessable amounts that are expected to arise from settling the liability's carrying amount as at the reporting date.The exception to this rule is that:

A) In the case of revenue received in advance, the tax base must be calculated as the liability's carrying amount less any amount of the revenue received in advance that has been included in taxable amounts in the current or a previous reporting period.
B) In the case of carry forward tax losses, the tax base must be adjusted for any consideration paid by a company within the group that is receiving the transferred tax loss.
C) In the case of a downward revaluation of a non-current asset, the tax base must be calculated as the decrease in the asset plus any amount expected to be received in the future inflated by the index for capital gains tax.
D) In the case of a warranty liability, the tax base must be calculated as the liability's carrying amount less any amounts paid out this period that have not been included in taxable amounts in the current period.
