According to the provisions of article 20 of Law 49/2002, taxpayers will have the right to deduct from the total amount, reduced by the deductions and bonuses provided for in Chapters II, III and IV of Title VI of the LIS , 35 percent of the deduction base. 

The amounts corresponding to the tax period not deducted may be applied in the settlements of the tax periods that conclude in the next ten years.

If in the two immediately preceding tax periods donations, gifts or contributions with the right to deduction have been made in favor of the same entity for an amount equal to or greater than that of the previous tax period, in each of them, the deduction percentage applicable to the deduction base in favor of that same entity will be 40 percent.

The basis for this deduction may not exceed 10 percent of the taxable base for the tax period.

Amounts exceeding this limit may be applied in tax periods ending in the next ten years.

Article 22 of Law 49/2002 establishes that the General State Budget Law may increase the percentages and limits of this deduction by a maximum of five percentage points. For these purposes, the percentage of 35 percent applicable to this deduction may be raised to 40 percent and the maximum limit of 10 percent to 15 percent.
