How the DGT's position has evolved

Settled doctrine High confidence 16 rulings · 2014–2024

Current position

The assumption of debt with release of liability without consideration constitutes a gratuitous legal transaction subject to Inheritance and Gift Tax. The tax base includes the outstanding principal, interest, and mortgage guarantee expenses. If the operation is a loan and not a gratuity, it is subject to Transfer Tax and Stamp Duty (ITP/AJD), although under current regulations such a transfer is usually exempt.

The DGT's position remains constant in classifying the assumption without consideration as a taxable event for Inheritance and Gift Tax. Throughout the rulings, it has been specified that the absence of 'animus donandi' (as in the repayment of loans or the liquidation of community property) excludes taxation as a gift. The evolution focuses on the delimitation of the tax base and the burden of proof to disprove the gratuitous nature of the transaction.
