How the DGT's position has evolved

Settled doctrine High confidence 16 rulings · 2014–2026

Current position

When operations with a right to deduction and other exempt operations are carried out jointly, the general or special pro-rata rule must be applied according to current regulations. If differentiated sectors exist, a separate deduction regime applies to each one. The deduction is limited to the percentage resulting from the proportion of taxable and non-exempt income relative to the total.

The DGT's position remains constant regarding the application of pro-rata mechanisms and differentiated sectors. Rulings have addressed specific scenarios, such as the inclusion of income from operations outside the territory of application or the involvement of investment assets, but without altering the structure of the deduction system.

Turning points

  1. V1715-14

    Establishes the mandatory nature of special pro-rata when the amount of deductible quotas under the general rule exceeds the special rule by 20 percent.

  2. V1436-18

    Specifies that the transfer of rural land, upon becoming part of development inventory, must be included in the denominator of the general pro-rata.

  3. V0744-20

    Allows the inclusion in the general pro-rata calculation of income from services provided outside the territory of application that would entitle a right to deduction within the territory.
