How the DGT's position has evolved
Current position
The tax accrues upon requesting the first definitive registration. To apply reduced rates for CO2 emissions below 120 g/km, this must be proven via a manufacturer's certificate or an official document. The exemption for rental activities requires the submission of Form 05 prior to registration, providing the technical data sheet, the IAE receipt, and documentation demonstrating compliance with the Law on Land Transport Management.
The DGT's position remains stable regarding the nature of the accrual and the application of exemptions. Recent rulings have specified the documentary requirements for the rental exemption and the accreditation of CO2 emissions for the application of specific tax rates.
