How the DGT's position has evolved
Current position
The imputation of gross income and purchases for the objective estimation regime depends on the temporal imputation criterion chosen by the taxpayer. If the accrual method is applied, income and expenses must be computed in accordance with accounting regulations, regardless of the invoice date or the collection date. If the cash basis (collections and payments) is chosen, the amounts actually received or paid are imputed.
The DGT's position remains stable throughout the sequence. The temporal imputation criterion for the objective estimation regime has always been subject to the taxpayer's choice between accrual or cash basis. Recent rulings simply reiterate the application of accounting regulations in the case of accrual.
