How the DGT's position has evolved
Current position
The maternity supplement is income from employment due in the period corresponding to the pension it supplements. When received in a period different from when it was due due to reasons not attributable to the taxpayer, the special rule of article 14.2.b) of the LIRPF (Personal Income Tax Law) applies. This requires the amounts to be imputed to the tax periods in which they were due by filing supplementary tax returns without penalties or interest.
The DGT's position is constant throughout the sequence. The criterion is maintained that the supplement is income from employment and that its imputation must be carried out in the years it was due through supplementary tax returns. No changes in the applied doctrine are observed.
