How the DGT's position has evolved
Current position
In dual entities, contributions from private entities are contractual in nature and are subject to IVA (Value Added Tax) if made for consideration. For the deduction of the tax, when there are taxable and non-taxable operations, a reasonable and homogeneous criterion for the imputation of the tax paid must be applied. In the case of basic research expenses without the aim of exploitation, these do not constitute a business activity for IVA.
The DGT's position remains constant in the distinction between business activities and activities of general interest. The use of a reasonable imputation criterion for the deduction of quotas in entities performing mixed activities has been consolidated. No doctrinal shifts are observed, but rather a systematic application of proportionality in the deduction.
Turning points
-
Establishes that in dual entities, quotas for goods and services intended exclusively for non-taxable operations are not deductible, allowing for an imputation criterion.
-
Reinforces the application of a reasonable imputation criterion for the deduction when the taxable person performs taxable and non-taxable operations.
