IMPORTANT: no 2025 or 2026 table has been published in the BOE (checked every BOE summary 01/11/2025-12/11/2026). The 2024 table is the last official one and keeps applying under the extension. Levels 6, 7 and 8 (and level 5 is above) are BELOW SMI 2026: under art. 34 bis and RD 126/2026 art. 3, these workers must receive at least 17.094 EUR/year (1.221 EUR x 14) for full time. CCOO-Servicios communiqué no. 18 (02/07/2026) reports a pre-agreement on a XXI convenio (4-year term, restructured tables, arrears for 2025 and 2026 once published in the BOE) — not yet published in the BOE as of 2026-11-12, so new amounts are unknown. Level 1 first-job graduates accrue plus convenio only after 1 year (art. 38.2). Max 1.792 effective h/year (art. 22). Signed by TECNIBERIA + CCOO + UGT; erga omnes. SMI 2026 (Real Decreto 126/2026, BOE 19/02/2026, effects 01/01-31/12/2026): 1.221 EUR/month (14 payments), 40,70 EUR/day, minimum annual 17.094 EUR for full time; any table amount below that is lifted to the SMI in annual computation.
