How the DGT's position has evolved
Current position
Form 303 is used for the self-assessment of IVA (Value Added Tax) under the general regime and for reverse charge operations of the taxable person when activities are carried out outside the equivalence surcharge regime. Boxes 123 and 124 are reserved exclusively for one-stop shop regimes. Under the cash accounting regime, acquisitions from entrepreneurs subject to said regime must be reported via aggregate breakdown in box 74.
There is no doctrinal evolution regarding Form 303, as the rulings address unconnected technical aspects. The criteria deal in isolation with the cash accounting regime, the application of pro rata, filing deadlines, rectification of self-assessments, and the use of specific boxes for the one-stop shop.
