How the DGT's position has evolved

Stable position High confidence 54 rulings · 2015–2026

Current position

The deduction for investment in primary residence is limited to the proportional share of each taxpayer's ownership. In co-ownership acquisitions, each subject may only deduct the amounts paid with their own funds that correspond to their percentage of ownership. If there is an excess payment regarding the ownership share, said excess is not deductible.

The DGT's position has moved from analyzing the nature of contributions and the dissolution of property communities to focusing on the application of individual tax deductions. No change in doctrinal criterion is observed, but rather a diversification of the factual scenarios applied to undivided property. The doctrine remains constant in that ownership and payment must coincide for the exercise of tax benefits.

Turning points

  1. V1768-20

    Establishes that the contribution of the abstract or ideal share of the co-owners is considered a special non-monetary contribution under article 87.1 of the LIS (Corporate Income Tax Law).

  2. V1915-23

    Specifies that the reduction in the number of co-owners without the extinction of the community constitutes an onerous transfer of assets.

  3. V1023-26

    Distinguishes that the extinction of a condominium over an indivisible asset is taxed under AJD (Stamp Duty), but if the community persists over other assets, a transfer subject to ITP (Transfer Tax) occurs.
