Japanese succession and residents of Taiwan

A system that taxes the recipient

Japanese inheritance tax is charged on each person who acquires property, rather than on the estate as a whole before it is divided. That differs in principle from several other systems. The scope of what is taxed depends on the domicile, nationality and past periods of residence in Japan of both the deceased and the person acquiring, but as a general matter assets situated in Japan fall within scope even where the recipient lives abroad. The detailed rules are intricate and have been amended more than once, so no single test will settle a case. What can be established early is a plain fact: which assets the family holds in Japan, and in whose name each of them stands.

What crossing two jurisdictions involves

• Establishing the heirs calls for Taiwanese household registration records, with certification and translation
• Japanese banks and the land registry generally require confirmation from every heir
• An estate division agreement needs the consent of all heirs, so allow time for papers to travel
• Changing the name on a property requires a registration, usually handled by a judicial scrivener
• The Japanese filing has a statutory deadline running from a set point, and lateness may carry additional charges
• Each jurisdiction applies its own domestic rules, so relief from double taxation must be checked case by case

Cash and time rarely align

The most common difficulty in a succession is not the amount of tax but the gap between the timing of the liability and the liquidity of the assets. Property cannot reliably be turned into cash quickly, while filing and payment run to a deadline; if Taiwanese formalities proceed in parallel, the movement of documents can add further weeks. Identifying the source of funds for tax during the owner’s lifetime therefore tends to be calmer than searching for a buyer afterwards. Possible directions include retaining a deposit balance within Japan, revisiting the role of insurance, or agreeing in advance the order in which assets would be sold. Each carries its own cost and limits, and suitability depends on the family’s assets and where its members live.

Wills, and agreement within the family

Where assets are held in Japan, a will covering the Japanese property can reduce the procedural burden later. It should be read against whatever has already been prepared in Taiwan, so that two documents do not conflict in effect or in content. The formal requirements, whether an executor may be appointed, and how the arrangement interacts with forced heirship should be confirmed with a lawyer on the facts. Often, though, what matters more than the paperwork is agreement within the family: who intends to keep an asset, who would prefer cash, and who will speak with the professionals in Japan. Our role is to organise the schedule and the inventory, and to introduce qualified specialists in each field who then act within the scope of their own practice.
