Japan's 2026 Home Renovation Tax Deductions: A Complete Guide

Japan runs four separate, government-set renovation tax programs in 2026 — a mortgage-linked tax reduction, an income-tax credit, a fixed asset tax cut, and a gift-tax exemption — each with its own eligibility test, formula, and filing calendar, unlike anything in a US, UK, Australian, or Singaporean tax code. The mortgage-linked reduction returns up to ¥140,000 (approx. USD 933) a year for 10 years; the income-tax credit returns ¥600,000–800,000 (approx. USD 4,000–5,333) in a single year. We walk through the official rate tables, a five-step worked example from Japan's Ministry of Land, Infrastructure, Transport and Tourism, the exact filing documents, and — for property investors — why none of these four programs apply to a rental unit at all.
