Form 390 - Technical assistance

Form 390. Simulator (Open)

The "Model 390. Fiscal year 2023. Simulator 390 (OPEN)" does not require electronic identification and allows a simulation of model 390 of the annual summary of VAT to be carried out.

The simulator does not allow the filing of the declaration.

In the initial window, fill in the identification data , which will not be validated against the Tax Agency census. You can start with a fresh declaration by clicking "Accept", or "Load" the data from a previous session saved from the same simulator (file with .ses extension).

After "Accepting" a notice will be displayed with the exemption assumptions for submitting Form 390. Review the information and click "Accept".

Access the different pages of the declaration from the "Sections" index or use the navigation arrows.

On some pages, you will need to click the pencil icon to enter more information.

If you have any questions about completing the form, go to the option " ADI . Need help"? in the lower right corner to link to Tax information and available assistance services.

You will also find the instructions for completing the form under the "?" button with the question mark in the top menu.

Using the " Save " button you can save the data, obtaining a file with the .ses extension that you can recover in subsequent sessions using the "Load" button, in the initial window and in the top button bar. 

When you save the file, it will be downloaded by default to the folder that your browser has set as default. You will also be able to select a different location. The file will be named NIF of the declarant-390-year of the declaration, with the extension .ses.

NOTE: The file with the .ses extension obtained when saving the simulation can only be loaded in the "Model 390. Fiscal year 2022. Simulator 390 (OPEN)". It is not possible to upload it to the form for the electronic submission of model 390.

Check for errors by clicking the " Validate " option in the top menu.

Any detected warnings or errors will be displayed. Notices are for informational purposes only and do not impede submission. Errors must be corrected in order to file the return.

The "Go to error" and "Go to notice" buttons direct you to the box or page that needs to be reviewed or corrected.

At any time you can obtain a draft of the declaration in PDF , from the "Preview" button, not valid for submission and save it using the option "You can click here to download the pdf ". For correct viewing of the draft you need a PDF viewer.

Click "Back to return" or start a new one with "New return".
