When this form applies
Modelo 030 is a personal tax-census declaration. It can be used for registration, certain NIF requests, a change of tax address and changes to personal information. For a person who carries on no business or professional activity and makes no payments subject to withholding, it is the usual route for these personal census updates. It is not an income tax return, a visa application or an application for a NIE.
When to choose another procedure
If you are in the business, professional or withholding census, tax-address changes normally use Modelo 036. There are limited exceptions allowing Modelo 030 for certain identification or marital-status changes. Modelo 037 was withdrawn from 3 February 2025; check the current Modelo 036 service. Do not use a personal-address update as a substitute for registering an autónomo activity.
What to prepare
Have your DNI or NIE/NIF, full name, current recorded details, new address and the actual date of change ready. Separate your tax address from a different address for notifications. Check supporting evidence for your specific cause, especially a NIF request or representation. Do not select a change in tax residence merely because you have changed home.
Spanish fields explained
Causas de presentación means the reason for filing; select only the changes you need. Datos identificativos means identity details. Domicilio fiscal is the address used in your tax relations; domicilio a efectos de notificaciones is where notices are sent. Representante concerns a person legally acting for you. Review which fields the official service activates for the selected reason.
Submit online yourself
Open the official AEAT procedure and select Modelo 030. Modificación o presentación. Use an accepted identity method such as Cl@ve Móvil, an electronic certificate or DNIe. Review the selected cause and all entered data, run validation and resolve errors. Complete the official signing and sending steps yourself. The service can import a compatible BOE file; an import or saved draft alone is not filing.
Paper submission
Use the official paper form and its instructions, rather than a PDF that imitates it. AEAT allows delivery to the relevant administration or delegation, or post to the appropriate office. Check appointment requirements before visiting. The electronic service’s Vista previa is a draft and is not valid for filing. The official paper form has its own identification and barcode process.
Deadlines and proof
For a tax-address change by an individual outside the business census, the general communication period is three months. If the relevant IRPF filing deadline ends sooner, the official instructions describe the earlier return route. Check the rule for your exact cause. After successful electronic filing, save the receipt, CSV and declaration copy. Changes may appear only after AEAT validates them.
Common questions
Does a padrón update also update AEAT? Treat the municipal register and tax census as separate procedures and verify AEAT’s own record. Can two spouses always file together? The official joint procedure requires the corresponding representation. Will Newcomer submit for me? No: you access the official channel and decide whether to sign and send.
