What are Japanese inheritance tax rates?
Japan has one of the world's highest inheritance tax rates: 10% to 55% on a progressive scale. The 55% top rate applies to shares exceeding ¥600,000,000. The basic exemption is ¥30,000,000 + ¥6,000,000 × number of legal heirs.
How is the tax calculated?
Step 1: Total estate - basic exemption = taxable estate. Step 2: Divide taxable estate by legal shares. Step 3: Apply tax rates to each share. Step 4: Sum all heir taxes to get total. Step 5: Distribute proportionally based on actual inheritance.
What assets are included in the estate?
All assets including: real estate (at cadastral value, typically 60-80% of market value), financial assets, life insurance over the exemption, business interests, and gifts made within 3 years of death. The family home may receive a special discount (小規模宅地).
What is the spousal tax deduction?
A surviving spouse can inherit tax-free up to ¥160,000,000 or their legal share (whichever is greater). This is one of the most powerful inheritance tax reductions and effectively means many couples pay no inheritance tax on first death.
