auto_awesome What this module does
AI-generated from the code · Odoo 19.0Lets Spanish companies prepare, calculate and file the AEAT Model 303 VAT self-assessment in Odoo, including the official BOE export file and the tax regularization journal entry.
This module adds the Spanish VAT self-assessment (Modelo 303) to Odoo's AEAT reporting area. Users create a 303 report, and Odoo automatically fills the tax boxes from the accounting entries and mapped taxes, then computes the totals.
- The report form shows the payable VAT, deductible VAT, the general scheme result, the amount attributable to the State, fees to compensate from previous periods, annual regularization, the settlement result and the final result type (to pay, to refund, to compensate or no activity).
- It automatically carries forward the pending amount to compensate from the closest previous filed report and limits how much can be applied.
- It blocks confirmation if a refund is expected but no bank account is selected, and rejects negative compensation amounts.
- It creates the regularization journal entry, including a line for compensation from previous periods, and exports the file in the official BOE format for telematic filing.
- Extra fields cover the 390 exemption data, main and additional IAE activity codes, SII and 347 obligations, and boxes for refunds already granted and petrol/diesel payments on account.
It appears under the AEAT menu as 'AEAT 303 model', with activity codes configured under 'AEAT 303 activity codes'. It works on l10n.es.aeat.mod303.report and l10n.es.aeat.mod303.report.activity.code, and is restricted per company.
