Can the Spanish Tax Agency fine you if you incorrectly reported your foreign income?

Not always, and here is the key point

The Supreme Court has just answered a question that affects many people who work, or have worked, outside Spain: if your employer told you that you did not have to pay tax on that income and you reported it accordingly, can the Spanish Tax Agency fine you later if it reviews your case and reaches a different conclusion?

The case: a doctor who worked in the Netherlands

An ophthalmologist carried out his professional activity in the Netherlands during the 2012 and 2013 tax years. His employer issued him with a tax certificate confirming that this income was exempt from taxation in Spain under article 7.p) of the Personal Income Tax Law, the rule that allows certain work performed abroad to be exempt from tax in Spain. The doctor filed his tax return accordingly, and his employer did not apply any withholdings.

Subsequently, the tax authorities reviewed his case, considered that the exemption did not apply, and demanded payment. In addition, they imposed a tax penalty for failing to pay the amount which, according to the Spanish Tax Agency, should have been declared. The taxpayer appealed the decision, but both at the administrative stage and before the courts, the rulings were in favour of the Tax Agency — until the case reached the Supreme Court.

What did the Supreme Court decide?

The question before the Supreme Court was this: does the fact that a taxpayer followed the certificate issued by their employer automatically exempt them from any liability? Or must each specific case be analysed to assess whether the taxpayer acted reasonably, as provided for in article 179.2.d) of the General Tax Law?

The Court first recalls that the tax obligations of the employer and those of the taxpayer are autonomous and independent. In other words, the fact that your employer certified an exemption does not automatically release you from your own obligations, nor does it prevent the Tax Agency from imposing a penalty.

However, the Supreme Court also clarifies that the opposite is not automatic either. That certificate can indeed be a key factor in proving that you acted in good faith, provided that other conditions are also met: there must have been a genuine interpretative doubt regarding the rule, and your conduct must have been diligent at all times.

Applying this criterion to the specific case, the Court held that the doctor had indeed travelled abroad, had carried out the work that could justify the possible tax exemption, had followed his employer’s official position, and had done so at a time when the application of article 7.p) of the Personal Income Tax Law gave rise to genuine interpretative uncertainty. For all these reasons, the Court concluded that there was no tax culpability justifying the penalty.

The judgment annuls the tax penalty, although it maintains the obligation to pay the tax debt claimed by the Spanish Tax Agency. In doing so, the Supreme Court establishes a clear doctrine: following your employer’s position does not automatically exempt you from liability, but it may be decisive in avoiding a penalty if you can also prove diligence and there was reasonable doubt as to how the rule should be interpreted.
