Our reports are not documents a machine spat out. They are designed under the supervision of our co-founders (Víctor, Rafael, Alberto and Martín) following the binding rulings of the Spanish tax directorate. If you are audited, the report serves as documentary evidence of where your funds came from and went, which makes defending your case far easier.
