SMI
SMI stands for Salario Mínimo Interprofesional. It is Spain's national minimum wage, set annually by the Spanish government after consultation with unions and employer associations. The SMI applies across all sectors and all regions of Spain, with no regional variation. In 2026 the SMI is set at approximately 1.184 euro gross per month for a 14 payment year (16.576 euro per year), equivalent to about 1.381 euro per month for a 12 payment year structure.
Why the SMI matters beyond minimum wage
The SMI is more than just the lowest legal salary for employees. It anchors a wide set of administrative thresholds across Spanish life. The Digital Nomad Visa requires the main applicant to earn 200% of the SMI (approximately 2.762 euro per month gross in 2026), with additional percentages for spouses and children. Many tax deduction thresholds, fines, exemption levels, and unemployment benefit calculations reference the SMI directly. The Seguridad Social uses the SMI as the floor for the lowest contribution brackets under RETA (the autónomo regime).
When the SMI rises, all these connected thresholds rise too. That is why the annual SMI announcement (usually in December or January, with retroactive effect from 1 January) gets attention well beyond the labour market.
SMI vs IPREM: do not confuse them
Spain has two different income reference indices: SMI and IPREM. SMI is the minimum wage, anchoring employment and labour thresholds. IPREM (Indicador Público de Renta de Efectos Múltiples) is a separate reference index, anchoring non employment thresholds: the Non-Lucrative Visa requires 400% of IPREM, social benefit eligibility uses IPREM thresholds, and legal aid is calculated against IPREM. IPREM is lower than SMI (approximately 600 euro per month in 2026), and the two have grown apart over the years. Mixing them up changes visa eligibility calculations significantly.
