SII (Suministro Inmediato de Información)

With the Spain - Base Layer, the SII (Llevanza de libros registro del IVA a través de la Sede electrónica de la AEAT) is handled by the Suministro Inmediato de Información en el IVA module. It sends the VAT data of customer invoices and vendor bills to the web service of the AEAT, or of the regional tax agency of the company. The SII is mandatory for companies with a turnover above 6 M€, for the taxpayers registered in the REDEME, and optional for the others.

Note

The standard Spain - SII EDI Suministro de Libros module described in the SII section of the Spain page cannot be installed together with the base layer.

Journals, fiscal positions, and taxes

  • On the sales and purchase journals, the Enable SII option (Localization Settings tab) is ticked by default. Untick it for a journal whose documents must not be sent.

  • The fiscal positions of the Spanish chart of accounts carry the SII data (registration keys, exemption and non-subject causes). Check them when you create a new fiscal position.

  • The taxes are sent according to the SII tax map, which covers the default Spanish taxes.

Send invoices

With the automatic method, a customer invoice or vendor bill is queued for sending when it is confirmed, and sent according to the Send Mode. The SII tab of the invoice shows:

  • the Description and the Registration key of the operation, proposed from the company settings and the fiscal position;

  • in the result section, the Send state, the CSV code returned by the tax agency, and the Send error if the invoice was rejected.

To send an invoice immediately, click Send now in the SII tab. To send several invoices, select them in the list view, and click Actions ‣ Send Invoices to SII.

If the sending failed, correct the invoice and click Send to SII. If a sent invoice is modified (for example, after resetting it to draft and confirming it again), the modification is sent again. To cancel a sent invoice in the SII, cancel the invoice, then click Send cancellation to SII.

Tip

In the invoice and bill lists, use the SII not sent, SII sent, and SII failed filters to follow up the sending, and correct and resend the rejected documents.
