If there is a National Health Insurance member in the household, a notice will be sent to the head of the household.
The National Health Insurance calculates insurance premiums on a household basis, and it is stipulated by law that the head of the household is obliged to pay them.

For details on who insurance premiums in the household, please refer to the insured person's name column in 5 “Basic Insurance Premium Calculation” in the insurance premium determination notice (or insurance premium determination notice).

The National Health Insurance premium is determined according to the income of the previous year (in the case of 2023, one year from January to December 2022) and the "per capita rate" to be paid by each insured person. It is determined by the sum of the amount.
Please refer to the following Yokohama-shi homepage for the details of insurance premiums such as insurance rates.
Premiums

Since both the income rate and the per capita rate have increased from last year, insurance premiums have increased accordingly.
In addition, the following reasons are the main reasons for the increase in insurance premiums.
・The number of members of the National Health Insurance in the household has increased.
・Due to a change in the number of households, etc., the reduced amount of insurance premiums has been changed.
・In terms of operating income, etc., the income did not change, but the amount of income increased due to a decrease in expenses to deduct.
・Having reached the age of 40 has resulted in a new amount of nursing care provided by the National Health Insurance.
・Insurance premiums are not calculated correctly because income has not been declared. (If there is a declaration, the income is subject to insurance premium reduction, but because it has not been declared, it is not eligible for insurance premium reduction and insurance premium has increased from last year.)

In this case, by submitting a “National Health Insurance Income Statement” to Aoba Ward National Health Insurance Section, the National Health Insurance premium will be calculated correctly.
You can fill out the “National Health Insurance Income Statement” at the counter or mail it to your home if you can contact us by e-mail, fax or telephone.
