Home Loan Tax Deduction

  • (applicable only to a purchaser who has purchased the property for the purpose of residence) 

  • (From January 1, 2014 to December 31, 2021)

The home loan tax deduction allows you to deduct 1% (or up to 400,000 yen) of your home mortgage remaining at the year-end from your income tax each year (for 10 years).

If the acquisition price is lower than the year-end mortgage balance, the deduction is calculated as 1% of the acquisition price.

If the deduction exceeds your income tax liability, the remainder may also be partially deducted from your residential tax.
