Suministro Inmediato de Información en el IVA Extension

+ + +

Beta License: AGPL-3 NuoBiT/odoo-addons

+

This module extends the OCA SII (Suministro Inmediato de Información en +el IVA) module with additional functionalities and fixes that are not +accepted or delayed by the OCA l10n_spain localization community.

+

All Features Provided:

+

1. CuotaDeducible Support (Partially Deductible Taxes)

+

For Received Invoices (Vendor Bills):

+
    +
  • Automatically calculates the actual deductible amount of VAT based on +tax configuration
    • +
  • Only includes the portion that is truly deductible (based on tax +repartition lines with account)
    • +
  • Adds the CuotaDeducible field to SII submissions for received invoices
    • +
  • Works for taxes mapped as SFRS (IVA Soportado) and SFRISP (IVA +Inversión del Sujeto Pasivo)
    • +
+

How it works:

+
    +
  • Extends account.move.line to track actual deductible amounts +during tax processing
    • +
  • Automatically sums deductible portions based on tax repartition +configuration
    • +
  • No configuration needed - works automatically if tax has partial +deductibility configured
    • +
+

2. Clave “06” Support (Grupo de Entidades - Modalidad Avanzada)

+

Problem Solved:

+

Companies using ClaveRegimenEspecialOTrascendencia = “06” (VAT group +in advanced mode) receive SII Error 1234 when submitting invoices +with both services and goods.

+

What the module does automatically:

+
    +
  • For Outgoing Invoices (Customer Invoices):
      +
    • Merges services (PrestacionServicios) and goods (Entrega) into a +single tax breakdown
      • +
    • Consolidates multiple tax lines with the same rate (TipoImpositivo) +into one line
      • +
    • Transforms from DesgloseTipoOperacion to DesgloseFactura structure
      • +
    • Calculates and adds BaseImponibleACoste field automatically
      • +
    • Rounds BaseImponibleACoste to proper decimal precision
      • +
    +
    • +
  • For Incoming Invoices (Vendor Bills):
      +
    • Calculates and adds BaseImponibleACoste field automatically
      • +
    • Ensures proper structure for AEAT validation
      • +
    +
    • +
+

Result: SII submissions pass AEAT validation without Error 1234

+

3. Extensible Tax Agency Hooks

+

For Advanced Customizations:

+
    +
  • Provides hooks in aeat.tax.agency model to extend SII web service +configurations
    • +
  • Methods _prepare_sii_wdsl_mapping() and +_prepare_sii_port_name_mapping() can be overridden
    • +
  • Allows custom modules to add new WSDL endpoints or modify connection +parameters
    • +
  • Useful for specialized tax agency configurations or testing +environments
    • +
+

When to Use This Module:

+

Install this module if you need:

+
    +
  • Partially deductible VAT reporting (CuotaDeducible field in received +invoices)
    • +
  • VAT group in advanced mode (modalidad avanzada) with clave “06”
    • +
  • Fix for SII Error 1234 when submitting invoices with services + goods
    • +
  • Custom tax agency configurations (extensibility hooks)
    • +
+

How It Works:

+

The module works automatically after installation:

+
    +
  • No configuration required for standard features
    • +
  • Only activates clave “06” transformations when registration key = “06” +is detected
    • +
  • Doesn’t affect other invoices - backwards compatible
    • +
  • CuotaDeducible is calculated for all received invoices based on tax +configuration
    • +
  • All transformations happen transparently during SII submission
    • +
+

Technical Details:

+

Models Extended:

+
    +
  • account.move - Adds SII invoice processing for clave “06” and +CuotaDeducible
    • +
  • account.move.line - Tracks actual deductible amounts during tax +processing
    • +
  • aeat.tax.agency - Provides extensibility hooks for custom +configurations
    • +
+

Key Methods:

+
    +
  • _get_sii_in_taxes_deductible() - Calculates deductible VAT amount
    • +
  • _get_sii_out_taxes() - Transforms tax breakdown for clave “06” +outgoing invoices
    • +
  • _get_sii_invoice_dict_in() - Adds CuotaDeducible and +BaseImponibleACoste to received invoices
    • +
  • _get_sii_invoice_dict_out() - Adds BaseImponibleACoste to sent +invoices
    • +
  • _process_aeat_tax_base_info() / _process_aeat_tax_fee_info() - +Track deductible amounts
