Italian tax court dismissed appeal as new law prohibits inductive plusvalence assessment based on registration tax value.

The Italian Supreme Court rejected the Revenue Agency's appeal against a regional tax commission decision regarding property plusvalence taxes. The taxpayers successfully argued against the tax authority's attempt to use the registration tax value as an inductive basis for calculating income tax on capital gains. The court ruled that a subsequent legislative change retroactively invalidated this method, mandating that plusvalence be calculated based on the actual sale price difference rather than the registration tax value.
