Supplementary Provisions, Article 8Special Provisions on Assessment of Insurance Premiums in Merged Municipalities
第八条（合併市町村における保険料の賦課に関する特例）
A merged Municipality prescribed in Article 2, paragraph (2) of the Act on Special Provisions for the Merger of Municipalities (Act No. 59 of 2004) may, in the case where, owing to a significant imbalance in the assessment of insurance premiums among the Municipalities concerned in the merger prescribed in paragraph (3) of that Article, it is found that assessing uniform insurance premiums over the whole of its area would be significantly inequitable, assess non-uniform insurance premiums to the extent of that inequity, limited to the fiscal year including the day on which the merger of Municipalities (limited to a merger carried out on or before March 31, 2030) took place and the following five fiscal years.
市町村の合併の特例に関する法律（平成十六年法律第五十九号）第二条第二項に規定する合併市町村は、同条第三項に規定する合併関係市町村の相互の間に保険料の賦課に関し著しい不均衡があるため、その全区域にわたつて均一の保険料の賦課をすることが著しく衡平を欠くと認められる場合においては、市町村の合併（令和十二年三月三十一日までの間に行われたものに限る。）が行われた日の属する年度及びこれに続く五箇年度に限り、その衡平を欠く程度を限度として不均一の保険料の賦課をすることができる。
