How the DGT's position has evolved
Current position
To exclude operations from the VAT deduction pro rata on the grounds that they are ancillary, two cumulative requirements must be met. The qualitative requirement demands that the operations involve a very limited use of goods or services subject to IVA (Value Added Tax) and maintain a relationship with the main activity. The quantitative requirement establishes that the operations must not be more significant than the main activity, regardless of the magnitude of the income.
The DGT's position has remained constant over time. Since 2016, the administration has systematically applied the same qualitative and quantitative requirements to determine ancillary status. No changes in doctrine are observed, but rather a repeated application of the criteria regarding the relationship with the main activity and the limitation of resources.
