Under the 2024 tax reform, the Japanese government strengthened tax credit for salary increase from the perspective of (a) easing the burden on citizens whose wage increases have not kept pace with rising prices, (b) aiming to achieve an economy where wage increases that fully exceed price increases are sustained and (c) supporting efforts to balance work and child-caring and promote the advancement of women.
The main points of the revision are the establishment of a new definition called “medium-sized enterprises” and the raising of the tax credit ratio through the establishment of additional deductions for childcare support and the promotion of women's activities.
This tax credit rules which apply to all enterprises (including corporate and individual enterprise) are as follows:
Enterprises that submit blue tax returns.
However, certain enterprises are required to publish their multi-stakeholder policy on their website by the end of the applicable fiscal year and submit a notification to the Ministry of Economy, Trade and Industry.
In case of corporations, certain enterprises are defined as those with capital of at least JPY 1 billion and at least 1,000 employees or those with over 2,000 employees, at the end of the applicable fiscal year.

Fiscal years beginning between April 1, 2024 and March 31, 2027 (excluding the fiscal year of incorporation).
The mandatory requirement and the 3 additional requirements are defined. The applicable tax credit ratio varies depending on the range of requirements that the enterprise meets. The maximum ratio is 35%.

The amount of tax credit is the amount of increase in the total salary of all domestic employees from the previous fiscal year multiplied by the following tax credit ratio for each requirement.

This article introduces the Business Office Tax, which needs to be considered when entities conduct business in offices or workplaces within cities with a population of 300,000 or more.
Starting in 2027, a revised minimum tax regime will apply to certain high-income individuals in Japan. While JPY165 million is used as a calculation threshold, additional tax is only triggered where the minimum tax exceeds the regular income tax liability. The reform is intended to ensure a minimum level of taxation, particularly where a significant portion of income is derived from investment or equity-based sources.
In recent years, international tax authorities have intensified scrutiny of cross-border structures involving low-substance entities, commonly referred to as “paper companies.” Japan is no exception and such structures continue to be examined under existing anti-avoidance frameworks, including the “Controlled Foreign Company (CFC) regime and treaty-based anti-abuse rules.
