How the DGT's position has evolved
Current position
The fee for special use of the local public domain for supply companies is calculated based on the gross billing revenue from supply services. Revenue from value-added services or deductions not provided for in the TRLRHL, such as reductions for electricity production activities, are not included. If the activity is not supply, but rather management or services, the general rule based on the market value of the derived utility applies.
The DGT maintains a consistent stance on the nature of fees for the use of public domain. It has specified that the special 1.5% regime is strictly limited to supply revenue, excluding accessory or management services. Likewise, it has rejected the application of deductions external to the TRLRHL for the calculation of the tax base.
Turning points
