Current position

Late payment interest with a compensatory nature is taxed as capital gains within the savings tax base. In cases of employment income received by resolution, the supplementary self-assessment for the corresponding tax year does not entail late payment interest. Conversely, failure to meet requirements for deductions or exemptions requires the regularization of the tax liability plus the corresponding late payment interest.

The DGT maintains a consistent position in classifying compensatory late payment interest as capital gains. No doctrinal evolution is observed, but rather the application of this criterion to different scenarios: from the failure to meet requirements for investment deductions to the receipt of employment income or the disqualification of housing.
