The Criminal Chamber of the Spanish Supreme Court, in its judgment no. 274/2026 of 9 April 2026 (cassation appeal 4481/2023), confirms that the foreign tax-residence certificate issued under a tax treaty —to which the Spanish Supreme Court, in the civil-administrative doctrine of judgment 778/2023, had attributed iuris tantum presumptive value (that is, a rebuttable presumption)— retains that same nature in criminal-tax proceedings. However, the presumption yields where there is compelling evidence of the contributor’s material presence in Spain for more than 183 days in the tax period. In that case, the certificate does not exhaust the evidential question and the contributor’s tax residence is located, for all purposes —including criminal purposes—, in Spanish territory.
The practical consequence, for the defensive purposes of the client with material ties in Spain, is demanding. The broader those ties —available habitual home, family unit, professional presence, recurring social and personal events—, the more solid the evidence of real residence abroad must be. The defensive file does not allow improvisation: a detailed calendar of day-by-day presence, backed by contemporaneous evidence (banking movements, immigration records, attendance at professional and personal events, lease or ownership contracts of a dwelling in the foreign jurisdiction), and an annual tax-residence certificate issued under the applicable tax treaty. Without that documentation, the certificate by itself does not withstand criminal scrutiny.
