1. Applicable Law (準拠法)

Under Japan's Act on General Rules for Application of Laws (法の適用に関する通則法, Article 36), the inheritance of a person is governed by the national law of the decedent.

Polish Civil Code (Kodeks Cywilny, Book IV) governs succession. As an EU member, Poland applies the EU Succession Regulation (Brussels IV): the law of habitual residence applies by default.

Renvoi (反致): May Apply

Under Brussels IV, renvoi is excluded for intra-EU cases. For non-EU situations (assets in Japan), Polish conflict rules under the Private International Law Act may lead to renvoi for immovable property located in Japan.

2. Tax Obligation Type (課税範囲)

Unlimited Taxpayer

Taxed on all worldwide assets.

Applies if: domiciled in Japan, OR foreign national with residence visa who has lived in Japan for 10+ years.

Limited Taxpayer

Taxed only on assets in Japan.

Applies if: not domiciled in Japan, OR foreign national who has lived in Japan for less than 10 years.

Japan has a tax treaty with Poland that may provide relief from double taxation.

3. Poland Inheritance Law

  • Forced heirship (zachowek): forced heirs receive a monetary claim equal to 1/2 of their statutory share (2/3 if minor or permanently incapacitated)
  • Forced heirs are descendants, spouse, and parents
  • Poland imposes inheritance tax (podatek od spadków i darowizn) at progressive rates, but close relatives (Group I) are exempt if they notify the tax office within 6 months
  • Community property (wspólność majątkowa) is the default matrimonial regime

Statutory Inheritance:

Spouse and children: equal shares (but spouse receives at least 1/4). Spouse and parents: spouse 1/2, each parent 1/4. Spouse alone: entire estate.

Frequently Asked Questions

Does Poland have inheritance tax?

Yes, but close relatives (Group I) are fully exempt if they notify the tax office within 6 months. For others, rates range from 3% to 20%. The Japan-Poland tax treaty provides additional relief.

What is zachowek and how does it work?

Zachowek is Poland's forced heirship mechanism. Forced heirs (descendants, spouse, parents) can claim a monetary payment equal to 1/2 of their statutory share (2/3 if minor or permanently incapacitated). It is a claim against the estate, not a right to specific assets.

Can a Polish notarial deed be used in Japan?

Yes. An Akt Poświadczenia Dziedziczenia with Apostille and certified Japanese translation is accepted as proof of heir status for Japanese property registration and bank procedures.
