Note

  • Nursing care costs are for those aged 40 to 65 (second insured persons under long-term care insurance).
  • The total income amount, etc. used in the calculation of the income tax rate is the total income amount for the year 2023 plus forest income, separate tax income, etc. For example, if you only have salary income, the "amount after salary income deduction" on your withholding slip will be your salary income, and this will be your total income amount, etc.
  • When calculating the income percent, a basic deduction of 430,000 yen will be deducted for each person with income. If the total income amount, etc. is 430,000 yen or less, the total income amount, etc. used for calculating the income percent will be considered as 0 yen. In addition, if the total income amount exceeds 24 million yen, the basic deduction will gradually decrease.
  • The income percent is for the income of all members of the National Health Insurance.
  • There are no income deductions (medical expense deductions, etc.) or tax deductions (dividend deductions, etc.) like income tax or resident tax.

[Q] For example, how much will the National Health Insurance tax be for the following households?

relationship age income
Head of household (self-employed) 50 years old 3 million yen
wife (part) 45 years old 1.5 million yen
child (student) 22 years old none

[Answer] The National Health Insurance tax is as follows.

Division Basic (all subscribers) Latter-stage elderly support money (all members) Nursing care portion (persons aged 40 to 65)
Income percent {(3 million yen - 430,000 yen) +
(1.5 million yen - 430,000 yen)
×5.73%
= 208,572 yen
{(3 million yen - 430,000 yen) +
(1.5 million yen - 430,000 yen)
×1.37%
= 49,868 yen
{(3 million yen - 430,000 yen) +
(1.5 million yen - 430,000 yen)}
×2.19%
= 79,716 yen
Equal division 3 people x 37,200 yen = 111,600 yen 3 people x 9,400 yen = 28,200 yen 2 people x 13,100 yen = 26,200 yen
subtotal 320,100 yen 78,000 yen 105,900 yen

Note: The subtotal amounts are rounded down to the nearest 100 yen for the basic, later and nursing care portions.
The calculation results in a total of 320,100 yen for the basic portion + 78,000 yen for the later portion + 105,900 yen for the nursing care portion = 504,000 yen for the national health insurance tax for one year.

The above calculation process is simplified for the sake of explanation. Please note that the actual payment amount may differ due to rounding and other factors.

The taxpayer is the head of the household.

Even if the head of the household is enrolled in social insurance, etc., if a member of the household is enrolled in national health insurance, the taxpayer will be the head of the household (Article 703-4 of the Local Tax Law, Inagi City National Health Insurance Article 1 of the Tax Ordinance). The head of the household in this case is called the "fictitious householder", and the entire household is called the "fictitious household". In addition, income percent, per capita rate to affect fictitious householder are not included when we calculate National Health Insurance tax.

Monthly tax will be charged according to the number of months of subscription

When we calculate National Health Insurance tax, we calculate according to the number of the participation months. From the month when we took out National Health Insurance until the month before the month when we withdraw, we become a target of taxation (when we withdraw in the same month as participation, share for the month is not taxed).
If you join or withdraw from the system or change the head of the household in the middle of the fiscal year, the tax amount will change and a tax amount change notice will be sent.
For those who reach the age of 75 in the middle of the fiscal year, it is calculated up to the month before the transition to the medical system for the elderly aged 75 or over.

When can I join

You can enroll in the National Health Insurance not from the day you apply for it, but from the day you actually meet the enrollment requirements, such as the day you move to Inagi City or the day you stop taking other health insurance. About National Health Insurance tax, it is levied retroactively to time when we met participation requirements. Please submit your application within 14 days.

If you have other health insurance

When health insurance is switched, such as joining social insurance or the National Health Insurance Association, it is necessary to notify the withdrawal from the National Health Insurance. If you do not complete the necessary procedures, you will have to pay both the National Health Insurance tax and your company's health insurance premiums. Please bring both your social insurance card and your National Health Insurance card, and complete the procedures within 14 days.

Even if you have no income, you must file a tax return.

National health insurance tax cannot be calculated correctly without filing a final tax return or municipal tax return. Even if your income in the previous year was low and you do not need to file a final tax return or municipal tax return, filing a return may qualify you for a reduction in your national health insurance tax or a lower limit on your self-paid medical expenses (all members (including fictitious heads of household) must file a return). Please be sure to file a return regardless of whether you have an income or not (even those receiving survivor's pensions must file a return).
If you have not yet filed your tax return and have been living in Inagi City since before January 1, 2024, please complete the filing procedure at the City Hall Taxation Division.
If you moved in on or after January 2, 2024, you must report to the ward, city, town or village where you were living as of January 1, 2024, and notify the National Health Insurance Section of your city hall. If you bring your tax or exemption certificate, the details will be reflected.
