Shortfall Benefits(Fixed-amount Tax Reduction Supplementary Benefits)

In fiscal year 2024, a benefit (the Adjustment Benefit) was provided to make up the difference for those who were expected to be unable to fully apply a fixed-amount tax reduction on their fiscal year 2024 income tax and resident tax (those whose fixed-amount tax reducation exceeded their pre-reduction tax amount).

In fiscal year 2025, this adjustment benefit amount will be recalculated based on your actual fiscal year 2024 income tax amount. If there is a shortfall, you are eligible to receive an additional shortfall benefit to make up the difference.

At this time, we are unable to answer specific questions regarding whether you are eligible for a shortfall benefit or the amount you may receive.

Check Here For Updates

We ask that you use the flowchart linked below under "Who is Eligible," or wait for application documents to arrive to check your eligibility.

Who is Eligible

You are eligible for a shortfall benefit if you meet the all the conditions for either Shortfall BenefitⅠor Shorfall Benefit Ⅱ, outlined below, AND your Certificate of Residence was registered in Yokosuka as of January 1, 2025 (or if you were not registered in Yokosuka but pay Yokosuka taxes).

Those who filed for an exemption under a tax treaty are not eligible.

You can use this flowchart(PDF:210KB) to check your eligibility.

Shortfall BenefitⅠ

Who is Eligible

When the fiscal year 2024 Adjustment Benefit was calculated, it was calculated using an estimate of what the 2024 income tax amount would be based on fiscal year 2023 income, etc. 

Therefore, once the actual amounts of fiscal year 2024 income tax, fixed-amount tax reducation, etc., are confirmed, you are eligible for a shortfall benefit if ther is a difference between your fiscal year 2024 Adjustment Benefit amount and the actual amount you were owed.

 FOR EXAMPLE:
  • If your income tax amount was lower than what it was the year before, due to circumstances such as unemployment, etc.

Estimated 2024 income [based on your 2023 income] >Actual 2024 income

  • If your amount of fixed-amount tax reduction or tax deductions increased, for reasons such as having more financial dependents than before, such as a new baby.

  • If your amount of resident tax for fiscal year 2024 was revised AFTER the fiscal year 2024 Adjustment Benefit, AND this revision made your amount of income-based resident tax lower (only for cases where the revised tax return was filed by June 2, 2025). This coould be due to reasons such as having had to file a revised tax return because certain dependents were not listed on your original return.

Benefit Amount

The benefit amount depends on the recipient, It is calculated based on the "shortfall amounts," i.e., the amounts of tax reduction that could not be fully applied to your income tax and income-based resident tax. The benefit amount is the combined total of these two shortfall amounts, minus the fiscal year 2024 Adjustment Benefit, rounded up to the nearest 10,000 yen.

Even if the actual adjustment amount you were owed (A) turns out to be less than what you received for your FY 2024 Adjustment Benefit (B), you will not be asked to return the excess payment.

Shortfall BenefitⅡ

Who is eligible

Those who meet ALL of the following:

  1. The amount of both your income tax and income-based resient tax before the fixed-amount tax reduction is 0 yen, so you are not eligible for the fixed-amount tax reduction.

  • Temporary Special Benefit for Households Newly Exempt from Resient Tax for FY 2024 (100,000 yen)

This is mainly blue return and white return filers, and people whose total income exceeds 480,000 yen.
