How the DGT's position has evolved
Current position
SATs are taxpayers for Corporate Income Tax (IS), which allows for the exemption of the transfer of their registered certificates from Transfer Tax (ITP). In service or supply operations to partners, the price must be equal to or higher than the cost, including overheads, to avoid adjustments. If the price is lower than the cost, the latter shall be applied for its calculation.
The DGT's position remains stable regarding the legal and tax nature of SATs, confirming their status as taxpayers for Corporate Income Tax (IS).
