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.
Stop re-typing Name, SSN/EIN, and Street Address across separate forms. Launch a pre-built JustFill B2B Packet to enter shared fields once and download a ZIP or merged PDF.
Enter contractor and payer details once to fill the W-9 and the 1099-NEC copy for the recipient.

2. Multi-Page Onboarding / Tax Packet Automation
Combine Modelo 145 with companion documents (e.g. W-9 + Direct Deposit Authorization + NDA, or I-9 + W-4 + State Withholding, or 2848 + 8821 + Tax Organizer) or batch-generate hundreds of copies from Excel/CSV.
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.
Download the official Modelo 145 PDF free from the AEAT Electronic Office (Sede Electrónica), procedure G603, and open it right in your browser on this page with JustFill to type every section and checkbox cleanly. You hand the completed, signed form to your employer — it is not submitted to the tax agency.
What each section of Modelo 145 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.
Your NIF (tax ID), surnames and first name (Apellidos y Nombre), and year of birth (Año de nacimiento) of the person making the communication.
Check exactly one: box 1 (single/widowed/divorced/legally separated with qualifying minor children living only with you), box 2 (married, not legally separated, whose spouse earns no more than 1,500 euros a year — enter spouse's NIF), or box 3 (any other situation, including if you prefer not to state it).
Disability degree (33%–65%, 65%+, plus need for assistance/reduced mobility), geographic mobility (date you relocated for a job after being unemployed), and the box for prior multi-year (over 2-year) income to which the irregularity reduction was applied.
Year of birth, year of adoption or fostering, disability degree, and the 'cómputo por entero' box for children/grandchildren living only with you, for dependents under 25 (or older if disabled) with annual income under 8,000 euros.
Year of birth, disability degree, and the count of descendants sharing care, for parents/grandparents over 65 (or younger if disabled) who live with you at least half the year with annual income under 8,000 euros.
Annual amount of court-ordered spousal compensatory pension (pensión compensatoria) and annual court-ordered child-support payments (anualidades por alimentos).
Checkbox for taxpayers who bought or renovated their main home before 1 January 2013 with a loan eligible for the IRPF home-investment deduction and whose total gross work income is under 33,007.20 euros a year.
Section 6: place, date and the recipient's signature (Firma del perceptor) declaring the data is true. Section 7: the employer's stamped, authorized signature acknowledging receipt of the communication.
A fictional salaried employee starting a new job in Madrid completes Modelo 145 for her company's HR department, reporting that she is married (her spouse earns over €1,500/year, so Family Situation 3 applies) and shares custody of one dependent child under age 25. All names and numbers are fictional.
NIF: 1234••••Z · Apellidos y Nombre: EJEMPLO GARCÍA, LUCÍA · Año de nacimiento: 1989 · Situación familiar: ☑ Casilla 3 (Married whose spouse earns > €1,500/year) · Discapacidad: None
Exactly one family-situation box (1, 2, or 3) may be checked; Box 3 applies when a married employee's spouse earns more than €1,500 annually.
Hijo 1 — Año de nacimiento: 2021 · Cómputo por entero: Unchecked (child lives with both married parents, so each parent claims 50% of the descendant minimum)
Reports a qualifying child under age 25 with annual income below €8,000 living in the family household.
Sections 3 and 4 left blank (no dependent ascendants over 65 or court-ordered alimony) · Section 5 unchecked (main home purchased after 01/01/2013)
Section 5 only applies to pre-2013 main-home mortgage deductions when total work income is below €33,007.20.
En Madrid, a 22 de octubre de 2026 · Signed by employee Lucía Ejemplo García (Section 6) and stamped/signed by Sample Iberia S.L. HR (Section 7)
The employee signs Section 6 and the company's payroll/HR department acknowledges receipt in Section 7 and retains the copy.
