Questão jurídica principal
Whether the special annual tax on the 2000 liquidation gain was correctly based on the full sale proceeds, including a deferred payment and a retained interest-free loan element.
Decisão extraída
The deferred instalment was only a postponement of maturity and could be discounted; the interest-free loan element also formed part of the proceeds.
Fundamentação extraída
There was no suspensive condition preventing income realisation. The contractual structure merely delayed payment, so the amount was properly included at discounted value. The loan component was economically part of the sale price and unaffected by the reserved buyback right.
