How and where to file the census declaration

You can submit Form 030 in print or electronically via the Internet.

The presentation on printed form must be made at the Delegation or Administration of the AEAT corresponding to your tax domicile at the time of submission, either by direct delivery or by mail addressed to the management office of the aforementioned Administration or Delegation.

For submission electronically via the Internet you can identify yourself with Cl@ve Mobile, or with a certificate or electronic DNI . You can access it on your own behalf or on behalf of third parties (social collaboration, power of attorney or succession).

In general, form 030 is completed individually.

You can only complete a single model , signed by both spouses , in the following cases:

• When you communicate the change of tax address or address for notification purposes, and the aforementioned addresses are the same for both spouses; and

• When both wish to simultaneously communicate the application for registration in the Census of Taxpayers or application for the NIF , the modification of the identification data or request a new accreditation card for the NIF .

If you submit Form 030 jointly by both spouses electronically via the Internet, each spouse must have a valid user certificate that allows online submission, so they must first have NIF and be identified in the Census of Taxpayers. In the electronic submission of a single declaration made by both spouses, one of the spouses must have been previously authorized by the other to submit the form and this authorization must be registered in the Registry of Authorizations.
