Voluntary contributions to British Social Security are not deductible for Personal Income Tax (IRPF)

The deductibility of expenses for Personal Income Tax (IRPF) is subject to a direct connection with the activity that generates the income. Recently, the Dirección General de Tributos (DGT) has clarified the tax treatment of contributions made to foreign social security systems, specifically in the case of the United Kingdom.

What the DGT has ruled

The advisory body has established that, for Social Security contributions to be considered a deductible expense from employment income, they must be linked to the work developed by the taxpayer for which they pay tax in Spain. In the case of contributions to British Social Security, if these are voluntary in nature and are not related to the labor activity performed in Spanish territory, they cannot be considered deductible expenses.

The resolution is based on the need for a causal link to exist between the contribution and the income being declared. If the taxpayer makes payments voluntarily to secure a future pension abroad, without such payments being a consideration or a requirement of their employment activity in Spain, current regulations prevent their application as an expense.

What this means for you

This criterion directly affects tax residents in Spain who, due to their professional career or personal situation, maintain links with the British social security system. If you make voluntary contributions to supplement your future retirement in the United Kingdom, you must be aware that you will not be able to use those amounts to reduce the taxable base of your employment income in your Spanish tax return.

What you should do

Given this situation, it is fundamental to analyze the nature of each contribution made abroad. It is necessary to distinguish between:

• Mandatory contributions derived from employment activity developed in Spain.
• Voluntary contributions intended for social welfare systems unrelated to employment activity in Spain.

Given the complexity of the applicable regulations and the importance of the correct linking of expenses, it is recommended to assess each particular situation to determine if there is a sufficient link that allows deductibility according to the IRPF Law and the General Tax Law.
