【For Foreigners Working in Japan】What is Nenmatsu Chosei/Gensen Choshuhyo? Explaining taxes in Japan!

In Japan, companies conduct year-end tax adjustments of their employees every year between November and December. At that time, employees are required to submit documents that are necessary to calculate the difference between their withholding income tax and the exact amount of income tax. If you are a foreign national working in Japan, you may have experienced some difficulties at year-end tax adjustment. In this article, we will explain about year-end tax adjustment and withholding tax statements in Japan.

1.What is nenmatsu chosei?

年末調整/ねんまつちょうせい (year-end tax adjustment) is an adjustment of the excess or deficiency of the income tax by comparing the income tax to be paid by the employee for the year and the income tax deducted from the employee’s monthly salary and bonus. Although the tax amounts are deducted from the monthly salary as withholding tax, they are just estimates. There may also be an over or underpayment when there is a change in salary or family structure, or career change during the year. Therefore, once the salary of the year is determined, the company recalculates the tax according to the employee’s salary between January and December, and adjusts the excess or deficiency and determines the amount of tax to be paid, on behalf of the employee.

Foreigners who have an address in Japan or have been living in Japan for more than a year are subject to year-end tax adjustment, since their tax is handled basically the same as Japanese workers.

On the other hand, those who have their address overseas or work in Japan on a working holiday are not subject to year-end tax adjustment.
