Many foreign business owners are surprised to learn that director compensation is treated differently from employee salaries under Japanese tax law.
In Japan, changing a director’s monthly compensation during the fiscal year may result in the salary becoming non-deductible for corporate tax purposes.
When Can Director Compensation Be Changed in Japan?
In Japan, corporations typically hold a general shareholders’ meeting approximately two months after the end of the fiscal year. At these meetings, shareholders approve the financial statements and determine the amount of the director’s compensation for the next period of executive duties.
However, small businesses typically determine this without holding shareholders’ meetings, because it’s often the case that the president is also the sole shareholder in these corporations. The period for executive duties extends from the day after the shareholders’ general meeting to the day of the next meeting. Therefore, under Japanese tax law, changes within the first three months of the fiscal period are permitted. The reason why it’s three months instead of two is because listed companies typically hold shareholders’ meetings about three months after the end of the fiscal year.
Why Is Director Compensation Usually Revised in the Third Month?
In small businesses, the full-fledged operational period for executives begins three months after the fiscal year-end. Thus, the executive’s compensation for the third month is typically seen as the new amount. Therefore, if companies adjust the executive’s compensation, the changes are made starting from the third month.
When Is Director Compensation Paid?
It’s customary to pay the current month’s compensation within that same month.
What Happens If Director Compensation Changes During the Fiscal Year?
If Director Compensation Is Increased
In cases where directors’ compensation is increased after the fourth month of the fiscal period, the increased amount is not considered an expense under Japanese tax law. For instance, if a corporation, whose fiscal year ends in December, increased the director’s compensation by 300,000 yen per month from September, the total amount of 1,800,000 yen (300,000 yen x 6 months from September to February) is not recognized as an expense under Japanese tax law.

If Director Compensation Is Reduced
Similarly, when a director’s compensation is reduced, the difference between the pre-reduction and post-reduction amounts is not recognized as an expense under Japanese tax law. For example, if a company, which ends its fiscal year in December, decreases the director’s compensation by 300,000 yen per month from July, the total of 1.200,000 yen (300,000 yen x 4 months from March to June, counting from the fourth month after the start of the fiscal period) is not recognized as an expense under Japanese tax law. In other words, any excess portion is disallowed under tax law.
