The program is extended through 2030 move-ins
Japan's FY2026 tax reform extended the home-loan tax credit for five years, covering qualifying homes occupied between January 1, 2026 and December 31, 2030. A major feature is improved treatment for the existing-home market. According to the Ministry of Land, Infrastructure, Transport and Tourism, borrowing limits were raised for certain highly energy-efficient existing homes, additional allowances were broadened for eligible families, and the deduction period for qualifying existing homes was extended to 13 years. A floor-area relaxation to 40 square meters was also expanded to existing homes, although some income and household categories remain subject to a 50-square-meter requirement.
Energy efficiency becomes a stronger resale attribute
Age, station proximity, seismic performance and management condition have traditionally dominated the valuation of Japanese existing homes. The revised tax framework gives certified energy performance additional financial relevance. Two similarly priced properties may produce different after-tax outcomes when their energy classifications and qualifying borrowing limits differ. For sellers and brokers, documentation proving the applicable performance standard may therefore become a more meaningful part of marketing. Buyers should nevertheless avoid assuming that every energy-efficient property automatically receives the maximum credit, because eligibility depends on several conditions including occupancy, income and financing.
Foreign buyers need to distinguish residence from investment
Foreign nationals may potentially benefit when they satisfy the applicable tax and occupancy requirements, but property ownership alone does not create entitlement to the home-loan tax credit. The program is fundamentally designed for qualifying owner-occupied housing and should not be confused with tax treatment for investment property or a second home. A nonresident purchasing a rental unit in cash, for example, is in a different position from a resident purchasing a qualifying home with a mortgage. International buyers should therefore evaluate property certification, occupancy timing, loan structure and their Japanese tax position together before treating the credit as part of the acquisition economics.
