How the DGT's position has evolved
Current position
The application of prorrata depends on the coexistence of taxable and exempt operations. In cases of professionals with activities from different CNAE groups where the difference in deduction exceeds 50 points, the differentiated sectors regime must be applied. Likewise, income from risk guarantees in hedging contracts is not considered a provision of services and is excluded from the prorrata calculation.
The DGT's position remains stable regarding the application of the prorrata rule in the coexistence of taxable and exempt activities. Recent rulings have not modified the basic concept, but have instead specified which elements, such as settlements for financial risks, should not be included in the prorrata calculation.
Turning points
-
Establishes that positive settlements from hedging contracts are not provisions of services and must not be included in the denominator for the prorrata calculation.
-
Specifies the application of the differentiated sectors regime when the difference in deduction percentages between activities from different CNAE groups exceeds 50 percentage points.
