How the DGT's position has evolved

Settled doctrine High confidence 12 rulings · 2014–2021

Current position

Under the community property regime, ownership of the dwelling is determined by the proportion of the contributions made by each spouse and the community property. Amounts paid using community funds to amortize the loan are imputed 50% to each spouse. The original owner can only count 50% of said community payments toward the deduction, added to their own separate contributions. The spouse who acquires an undivided share through community funds after the abolition of the deduction is not entitled to apply it.

The position of the DGT remains constant in determining joint ownership based on contributions. The criterion repeatedly establishes that the use of community funds to amortize debt generates shared ownership that limits the right to the deduction for the spouse who acquires the share after 2012. No changes are observed in the interpretation of the 50% imputation of payments to each spouse.
