About equalization of special collection of medical care premium for elder senior citizens

Last update date June 7, 2023

What is special collection?

The method of paying insurance premiums from pension is called "special collection." Special collection is divided into "provisional collection" and "main collection" depending on the month of payment.

"Provisional collection" and "Main Collection"
Provisional collection Premiums paid by the pension in April, June and August. In principle, the monthly premium is the same as the amount paid in February.
This collection The premium paid by the pension paid in October, December, and February of the following year. After the annual premium amount is determined (July), the remaining amount after subtracting the amount of insurance premium paid by provisional collection It becomes the amount.

What is leveling?

For those who have a large difference between the provisional collection amount and the final collection amount, adjust the insurance premium amount in June and August so that the amount of insurance paid each month will be as even as possible throughout the year. It is called "leveling".
Even if the premium amount in June and August increases due to the leveling, the premium for October, December and February of the following year will decrease, so the total premium for the final year will not change. However, the leveling is calculated assuming that the annual premium amount for the previous year and this year are the same, so this does not apply if the annual premium has changed due to changes in income.

Targets for leveling

Payment of premiums by special collection continue, and insured persons who meet the following conditions are eligible for leveling.

[Calculation formula for applicable conditions (in the case of leveling in FY2023 leveling)]
Annual premium for FY2022 x 1/2 - February 2023 premium x 3 ≥3,000 yen

However, those whose term discount amount after the leveling is 110,000 yen or more and the term discount rate that increases due to leveling is 73,300 yen or more are not eligible for leveling.

Calculation method for leveling

The calculation method of the insurance premium after standardization is as follows.

[Calculation formula for each month's premium (in the case of leveling in FY2023)]
  Calculation formula
Premiums in April The same amount as the February 2023 premium [*1]
Premiums in June (Annual premium for FY2022 x 1/2 [*2] - April premium) ÷ 2 [*3]
