How the DGT's position has evolved
Current position
The exemption of per diems under Article 9 of the IRPF (Personal Income Tax) Regulations is only applicable to income from employment derived from an employment relationship. In the case of persons without an employment relationship, such as arbitrators, allowances are only non-taxable if the entity directly provides the means of transport and accommodation. If expenses are reimbursed without proving their strict necessity or if lump-sum amounts are paid, these amounts are taxed as income from employment.
The DGT's position has remained constant since 2014. The criterion establishes that the absence of an employment relationship prevents the application of the per diem exemption, unless the entity directly assumes the transport and accommodation expenses. The rulings repeatedly confirm that the reimbursement of expenses without strict proof or the payment of lump-sum amounts constitutes taxable income.
