odoo-addon-account-tax-rounding-method 18.0.1.0.0.3

Use Cases / Context

By default, Odoo uses the “HALF-UP” method to round tax amounts. However, in some regions, such as Japan, some industries have a common practice of rounding down instead. This module accommodates various regional practices by providing configurable tax rounding options: Half-up, Round-up, and Round-down.

Configuration

1. Set the company-wide default

   • Go to Accounting (or Invoicing) → Configuration → Settings

   • In the Tax Rounding Method section, select the rounding method to apply by default for all transactions

2. (Optional) Set a partner-specific rounding method

   • Go to Contacts → Select a partner

   • In the Accounting tab:

     • Select the rounding method to apply for that partner in the Tax Rounding Method

3. Priority of settings

   • If partner-specific rounding is enabled, it will override the company-level setting

   • If not enabled, the company-level setting will be used

Usage

With the tax rounding method set to “Half-up”, if you create an invoice in JPY with the following line:

• Quantity: 1

• Unit Price: 15

• Tax: 10% (excluded)

the calculated tax amount will be 2.

With the tax rounding method set to “Round-up”, if you create an invoice in JPY with the following line:

• Quantity: 1

• Unit Price: 13

• Tax: 10% (excluded)

the calculated tax amount will be 2.

With the tax rounding method set to “Round-down”, if you create an invoice in JPY with the following line:

• Quantity: 1

• Unit Price: 15

• Tax: 10% (excluded)

the calculated tax amount will be 1.
