Form for paper presentation of model 303 of 2022 and previous years (pre-declaration)
For paper presentation the "Model 303. VAT Self-assessment" you have a form to complete online and obtain the PDF with the declaration, previously validated by the server of the AEAT.
Since April 1, 2021, the requirements for access to the pre-declaration of form 303 have been modified.
Until now, this procedure allowed unauthenticated access, that is, anyone could generate pre-declarations for any taxpayer susceptible to submitting a pre-declaration.
With the change implemented in the pre-declaration service of model 303, basic authentication is required: DNI + Validity date, if it is a permanent DNI the date of issue will be required, or NIE + support number.
Only the NIF of natural persons will be admitted. In the case of entities, the NIF of the natural person making the declaration will be entered.
Starting in May 2021, pre-declarations from natural persons may only list the authenticated owner as the holder of the pre-declaration. In the case of entities, the NIF of the natural person making the declaration will be entered and the entity's data will subsequently be indicated on the form.
Fill in the Period, the NIF and the Surname and first name or the Company Name. If you have a file previously generated from the form (SES extension), use the "Load" button to recover the data. Otherwise, click "Accept".
You will access the "Identification" window of model 303. Make sure you answer all the questions correctly (YES / NO).
In the upper button panel you will find all the model's functionalities.
The button " Identification data " directs you to the previous window, where you can consult the data entered, modify some of them or load the data file (SES).
You can see the section index by pressing the " Sections " button or access the different pages with the navigation arrows.
Press " Draft " to obtain a pdf with the data entered so far. The document is not valid for presentation, but can serve as a reference.
The " Save " button allows you to obtain an SES file with the declaration data, which you can later retrieve from the "Load" option in the identification data window. The generation of the file does not require that the declaration be validated (it may contain errors or be incomplete). If you do not select a directory, this file will be automatically saved in the system's "Downloads" folder or in the directory set by the browser to save downloaded files. The name of the file will be NIF of the declarant-303-ejercicio.ses
Before submitting the return, use the " Validate " button to check for any warnings or errors. A list will appear with the "Errors and warnings" detected. The "Go to Notice" or "Go to Error" buttons will directly show the box or section that you must correct.
Remember that the notices are informative and do not prevent the presentation. On the contrary, errors must be corrected.
Access the last page to check the result of the declaration. Press "Select Deposit/Return".
If the type of declaration is "To be deposited", the section will be enabled to include the bank account. It will not be necessary to complete it if the payment is to be made in cash or if a deferral is to be requested.
If the result is negative, select "To compensate" or "Refund request" (only for the last period). You must include an account number IBAN in which you appear as the owner, where the return will be made. It can be an account opened in Spain or abroad ( EU / SEPA ).
After selecting the type of declaration, and once the declaration has been validated without errors, press " Generate pre-declaration ".
