Account Tax Rounding Method

Account Tax Rounding Method

This module provides the ability to configure tax rounding methods in invoices and other business documents such as sales orders and purchase orders. Supported methods include Half-up (Default), Round-up, and Round-down.

Only ‘exclusive’ taxes are supported, and the rounding behavior is limited to the round_globally option of the tax_calculation_rounding_method. It assumes that the round_per_line method is not used in Japan.

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.
