When a move overseas or a gift of assets is carried out, the tax outcome is not necessarily final. An assessment may arrive years later, followed by an administrative appeal and litigation before the matter is resolved.

More than a decade can separate a transaction from the final resolution of a dispute over its tax treatment.This length of time is an essential consideration in tax planning.

This article examines the Takefuji gift tax case, in which our firm provided tax support, and the nonresident-status case concerning a move to Singapore decided by the Tokyo District Court in 2023. We look beyond who won to the years required to reach the outcome. We also compare earlier domicile cases to identify the facts that influenced the decisions.

The Takefuji case: Approximately 11 years and 2 months from gift to Supreme Court judgment

The Takefuji case concerned whether the taxpayer was domiciled in Japan when receiving a gift of an equity interest in a foreign corporation. The gift occurred on December 27, 1999, and the Supreme Court judgment was issued on February 18, 2011.

A district court victory was followed by a high court defeat and then another victory at the Supreme Court.Arguments accepted once were rejected, prolonging the wait for a final decision. Even the interval from the district court judgment to the Supreme Court judgment was approximately 3 years and 9 months.

The dates and outcomes at each court are based on the full Supreme Court judgment published by the NTA. For our firm's support, see our announcement concerning the Takefuji judgment summarizing in

The 2023 nonresident judgment: Approximately 9 years and 10 months from departure to district court judgment

The other case concerned whether an individual remained a Japanese resident after moving to Singapore. It involved changes in life and business accompanying the move and disputes over subsequent returns, rather than the same transaction or tax regime as the Takefuji case.

The court rejected the taxpayer's position for 2013 and 2014 but found the taxpayer to be a nonresident for 2015.Approximately 5 years and 5 months passed from assessment to district court judgment, and approximately 3 years and 8 months even from filing suit. Although the case did not reach the Supreme Court, approximately 9 years and 10 months had passed since the departure date in the notification.

For the procedural history, see page 6 of the judgment; for the outcome and confirmation that it became final, see page 1. The issues and amounts by year are set out in our announcement introducing this judgment.

Distinguish this from saying “the trial took 10 years”

The approximately 11 and 10 years described here run from the gift or departure to judgment. They do not mean litigation or a tax audit continued throughout that period. Nor does the departure date in a moving notification necessarily establish the date on which the person became a nonresident for tax purposes.

From the taxpayer's perspective, however, the starting point is not simply the day a lawsuit is filed. After choosing a destination, establishing a life there, moving assets, and filing returns, those decisions are challenged.Measured from business and life decisions, the time to resolution exceeds the litigation period.

Even a victory cannot restore the time spent waiting

The larger the amount in dispute, the heavier the burden while awaiting resolution. Finding records, explaining past conduct, and consulting professionals require time and money. The impact can extend to family and business as well as the individual.

Moreover, an administrative appeal does not automatically suspend tax collection. The principle that enforcement is not suspended is explained in the NTA Tax College textbook on the Act on General Rules for National Taxes. Whether payment deferral or other relief is available requires separate consideration.

Even if tax ultimately canceled is refunded, lost business opportunities, constraints on daily life, and psychological burdens are not simply reversed.The issue cannot be dismissed by saying, “As long as we win in the end.”These are potential burdens in general, not an attempt to speculate about the feelings or costs of the parties in each case.

What can we learn by comparing past judgments?

The 2023 judgment cites the Supreme Court's Takefuji judgment when setting out the framework for determining domicile.Although the cases are separate, they share the principle of identifying the principal base of life from objective facts.However, different facts and applicable tax laws can produce different conclusions.

First, distinguish the types of tax. Resident and nonresident status under the Income Tax Act is not the same as the scope of inheritance and gift tax liability. Under current inheritance tax rules, foreign assets may be taxable even when the heir lives overseas. Winning an earlier domicile case does not establish that an inheritance or gift today will also be tax-free.

Do not look for a single condition that guarantees the outcome

Days present, housing, work, family, and assets are all evidence, but relying on just one is risky. The NTA's guidance on determining status for people staying in multiple countries also calls for a determination based on objective facts.

The lesson from the cases is not to copy the number of days spent abroad by a successful litigant, but tomake it possible to explain to others where your life and work are rooted. The difficulty of this overall assessment contributes to lengthy disputes and uncertainty in advance.

Treat pre-transaction review and subsequent recordkeeping as a continuous process

Three points are important for taxpayers preparing for this risk.

• Before acting:Identify the facts that affect the tax determination and which version of the law applies.
• After acting:Keep ongoing records explaining actual living and business circumstances, alongside contracts and tax filing documents.
• If a dispute arises:Consider the prospects of the arguments, funding burden, required documents, procedural deadlines, and time to resolution.

Years later, personnel may have changed and emails or travel records may be difficult to find. In addition to satisfying statutory retention periods, records needed during an ongoing dispute must be protected from loss.

A tax system clear enough to avoid litigation

This is not a problem that taxpayer preparation alone should solve. If eligibility requirements are unclear and a conclusion requires years of litigation, the system itself needs improvement.

For example, residency rules could clearly specify quantitative criteria such as days present, together with exceptions, in legislation. The UK's residency test combines day counts with ties involving work, family, and other factors. It is not simply a system in which “183 days decides everything,” but its explicit decision process offers a useful reference.

Clear rules do not eliminate factual disputes. Even so, expanding taxpayers' ability to determine their obligations in advance is highly valuable.

A simple, clear tax system that avoids the need for disputes is preferable to one in which taxpayers can win tax litigation.The system should be reconsidered without assuming that taxpayers must endure years of uncertainty.

The timelines in this article compare two specific cases; they do not represent the average duration of tax litigation. Each case was decided under the law and facts of its time. Current overseas moves, gifts, and similar matters require individual analysis under current law.
