Imputation of professional career back pay in Personal Income Tax (IRPF)

The Dirección General de Tributos (DGT) has clarified the tax treatment of retroactive payments derived from professional career progression. The central issue lies in determining which tax year these earnings must be declared when they are received in an accumulated manner.

What the DGT has resolved

The body establishes that back pay for professional career progression must be imputed to the tax period in which it becomes due. Due date is determined by the administrative resolution that grants said payments. If, due to circumstances beyond the taxpayer's control, the actual collection occurs in a tax year different from when it became due, the amount must be imputed to the year in which the resolution made it due through the filing of a supplementary tax return.

Furthermore, the DGT confirms that, since it involves a generation period of more than two years being imputed to a single tax year, the taxpayer is entitled to apply the 30 percent reduction provided for in the regulations, provided that this benefit has not been applied in the previous five tax periods.

What this means for you

If you are a worker receiving back pay following an administrative recognition of your professional career, you should not declare the income in the year you receive the money in your account, but rather in the year the administrative resolution ruled that the money was already yours. This may imply the need to rectify tax returns from previous years to comply with the regulations of Law 35/2006 (LIRPF) and Law 58/2003 (GT).

What you should do

It is necessary to precisely identify the date of the administrative resolution that grants the back pay. Upon receipt of these payments, you must verify if the temporal imputation is correct to avoid penalties. In cases where the timing requirements are met, you should ensure the application of the 30 percent reduction to optimize your tax burden. It is recommended to assess each particular situation to determine whether filing supplementary tax returns is appropriate.
