Official Modelo 145 from Agencia Estatal de Administración Tributaria (AEAT / Agencia Tributaria), Spain
Modelo 145 is the Spanish Agencia Tributaria (AEAT) form an employee uses to report their personal and family situation to their employer (the payer) so the company can calculate the correct IRPF income-tax withholding on their salary, under Article 88 of the IRPF Regulation. The worker completes and signs it; the employer keeps the copy and acknowledges receipt — it is not sent to the tax agency. JustFill lets you fill Modelo 145 online free: it auto-detects the fields so you can type or dictate and download a clean PDF.
Modelo 145 is the official Agencia Tributaria (AEAT) form titled "IRPF. Retenciones sobre rendimientos del trabajo. Comunicación de datos al pagador." Spanish employees use it to communicate their personal and family circumstances — marital status, dependent children, ascendants, disability, court-ordered support payments — to their employer so the company applies the correct IRPF withholding (retención) to their payroll. Unlike most tax forms, Modelo 145 is not filed with the tax agency; the worker hands the signed form to the payer, who keeps it and acknowledges receipt. You submit it when you start a job and update it whenever your situation changes. With JustFill you can fill Modelo 145 online free — the AI detects each box and checkbox, you type or dictate, and download a print-ready PDF without Adobe.
