This module address the undue tax requirement for Thailand

In Odoo, cash basis feature is being used to cover case of undue tax (due on payment). This can answer the issue about undue tax in Thailand partially. For customer invoice/payment, Odoo's cash basis alone is enough.

But for supplier invoice/payment and expense, where tax invoice number and tax date is given from vendor. This module will provide ways for user to do so on vendor bill (for normal tax) and in supplier payment (for undue tax which is due on payment).

.. IMPORTANT:: This is an alpha version, the data model and design can change at any time without warning. Only for development or testing purpose, do not use in production. More details on development status <https://odoo-community.org/page/development-status>_

Table of contents

.. contents:: :local:

Configuration

For Sales Taxes (tax scope = Sales), there is option to run Tax Invoice number by sequence model. If set properly, Tax Invoice Number will be using this sequence instead of customer invoice number / payment number

• Goto Accounting > Configuration > Invoicing > Taxes
• For sales tax, choose 'Tax Invoice Sequence' (or create new one)
• Make sure you also set the same sequence for the same tax on payment too. I.e., Output VAT7% and Undue Output VAT7% must select the same sequence, both both of them will result in same Tax Report

Note: this option is not avaiable for purchase tax, because the Tax Invoice Number is from vendor, and are filled manually.

Usage

With this, 2 new tax related fields will be introduced in account.move.tax.invoice

1. tax_invoice_number : Tax Invoice Number
2. tax_invoice_date : Tax Invoice Date

In customer invoice, both field will be defaulted by Odoo's document number and date. But in supplier invoice, both field must be filled by user with tax invoice number and date from vendor.

Note: The new table account.move.tax.invoice is the main source of Thai VAT Report
