How the DGT's position has evolved
Current position
For the limit under Article 16 of the LIS (Corporate Income Tax Law), income and expenses of a financial nature linked to business indebtedness are computed. In the case of variable commissions that offset results, only the portion corresponding to the difference between financial income and expenses is included in the net financial expense. Results from financial derivatives only count if they are accounting hedges for debt, excluding those that cover price risks to stabilize procurement costs.
The DGT has maintained a criterion of homogeneity between financial income and expenses, but has progressively refined the scope of this item. It has moved from a general definition of expenses and income related to debt to establishing specific criteria for the segregation of variable commissions and the distinction between debt hedges and price risk hedges.
Turning points
-
Links the determination of net financial expense to the nature of the accounting entries in the PGC (General Accounting Plan) (item 13), conditioning its inclusion on the applicable accounting regulations.
-
Introduces the need to segregate the variable commission according to the nature of the items it offsets, integrating only the portion corresponding to the difference between financial income and expenses.
-
Distinguishes between accounting debt hedges, which count toward the limit, and derivatives that cover price risks to stabilize costs, which are excluded.
