Taxpayers applying this deduction for internal double taxation must complete the row «DI internal 2025» in the manner detailed below:

  • The row "Internal DI 2025" It is intended to collect the amounts of the deductions to avoid internal double taxation regulated in section 1 of the twenty-third transitional provision of the LIS generated in 2025, and which were transferable to subsequent tax periods due to insufficient full tax liability.

  • In the column "Deduction generated" The amount of the deductions to avoid internal double taxation regulated in section 1 of the twenty-third transitional provision of the LIS generated in 2025 will be collected.

  • In column "Applied in this settlement" the part (or the whole, if applicable) of the amount corresponding to the previous column "Deduction generated" that is applied in the settlement corresponding to the period subject to settlement will be recorded.

    Keep in mind:

    • He section 2 of the Fifteenth Additional Provision of the LIS It establishes that taxpayers whose net turnover is at least 20 million euros during the 12 months prior to the date on which the tax period begins, must take into account that the amount of the deductions to avoid international double taxation provided for in articles 31, 32 and 100.10 of the LIS, as well as that of those deductions to avoid double taxation referred to in the twenty-third transitional provision of this Law, may not jointly exceed 50 percent of the taxpayer's full tax liability.

    • Information on the net amount of turnover for the twelve months prior to the start date of the tax period must be included on page 1 of Form 200, in order to determine the application of minimum taxation (Article 30 bis LIS). 

      The option selected by the taxpayer will also be taken into account to determine the limits in the calculation of accounting corrections arising from the application of article 11.12 of the LIS, the compensation of negative tax bases and the compensation of quotas for losses of cooperatives, so once the table on page 1 of form 200 has been completed, it will not be displayed again on other screens.

    • In box [01280] the total amounts entered in the column "Applied in this settlement" will be recorded, which must be transferred to box [01280] on page 14 of form 200 regarding the settlement of the Tax.

  • In column "Pending application in future periods" the part of the deduction corresponding to column "Deduction generated" that was not included in the box corresponding to the column "Applied in this settlement" will be recorded.
