Supplementary Provisions, Article 2Transitional Measures Accompanying the Partial Amendment of the Employees' Pension Insurance Act
第二条（厚生年金保険法の一部改正に伴う経過措置）
Among persons who acquired status as an insured before the day this Act comes into effect and have continuously held status as an insured until that day (excluding persons who have status as a class 4 insured person), for a person whose standardized monthly amount of remuneration for the month preceding the month that includes the day this Act comes into effect is 18,000 yen, with regard to the standardized remuneration for the period from the month that includes the day this Act comes into effect until September of that year, the provisions of Article 20 of the Employees' Pension Insurance Act as amended by this Act apply as if the person had acquired status as an insured on the day this Act comes into effect. In this case, if the person is an insured under health insurance, notwithstanding the provisions of Article 22, paragraph (1) of the Employees' Pension Insurance Act, the amount of monthly remuneration that served as the basis for the person's standardized remuneration under the Health Insurance Act (Act No. 70 of 1922) in the month that includes the day this Act comes into effect is deemed to be the amount of monthly remuneration that serves as the basis for standardized remuneration under the Employees' Pension Insurance Act.
