+
+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
