Current position

For the calculation of annual income limits in deductions for disability or ascendants, the algebraic sum of net income, imputed income, and capital gains or losses is used. Regarding income from employment, the net income is calculated after applying the reduction from Article 18 and the specific expense of 2,000 euros. Concerning the reduction from Article 32.1, the income must be non-habitual, with regularity being assessed based on the individual income of the taxpayer.

The DGT's position remains stable in determining net income for the calculation of income limits. A consolidation is observed in the algebraic sum calculation method for disability deductions, specifying the application of specific reductions from Article 18 and the 2,000-euro expense. There are no fundamental changes, but rather greater technical precision in the integration of concepts.
