Understanding the Tax-Accountant Profession: A Structural Lens for Evaluating Professional Support

2026-07-01

"What do you think of my tax accountant?" Foreign wealth holders in Japan ask us this repeatedly. It sounds like a question about service quality — but in tax matters, the value of professional support rests not on impressions but on the framework of the law. This article sets out, as general tax information, the framework of the licensed tax accountant (zeirishi) profession and the structural lens worth applying when evaluating professional support.

The Profession's Mission Is "Proper Realization"

Article 1 of the Certified Tax Accountant Act defines the profession's mission as achieving "the proper realization of tax obligations." The word the statute uses is proper — neither overstated nor understated, but the correct tax burden in conformity with the law. That is the starting point in the framework.

What matters is that this "proper" outcome must follow from correctly choosing the regimes that can apply. Japanese tax law contains many regimes that take effect only when a qualifying taxpayer elects them. Without the election, the effect does not arise.

Whether a Regime Is Elected Shapes the Outcome

Some concrete examples:

  • The simplified consumption-tax regime (Consumption Tax Act, Art. 37) — a business whose taxable sales in the base period are ¥50 million or less may elect, by notification, its method of calculating consumption tax. It is an elective regime; whether it is elected can change the amount payable.
  • The blue-return special deduction (premised on approval under Income Tax Act, Art. 143, and granted under Special Taxation Measures Act, Art. 25-2) — an individual approved for blue-return filing may claim a deduction of up to ¥650,000, subject to approval and to meeting the requirements.

These regimes work only when one knows them, elects them within the deadline, and meets the requirements. One axis for evaluating professional support is whether such electable regimes are considered in advance — before the year-end adjustment or the financial close — rather than after the fact.

Cross-Border Assets Add Another Dimension

Where assets or income sit in a home country, the axes multiply: the foreign tax credit that relieves double taxation on tax already levied abroad (Income Tax Act, Art. 95), the application of tax treaties, and compliance with reporting regimes such as the Overseas Assets Report. A framework built solely around domestic tax cannot fully handle these. Whether the international element can be grasped as a structure is what is tested here.

Procedural Tools the Framework Provides

The profession's framework also embeds procedural mechanisms that support the taxpayer.

MechanismStatutory basisSubstance
Authority to act as agentCertified Tax Accountant Act, Art. 30When acting as a tax agent, a document evidencing that authority must be filed with the tax office
Attached-statement regimeCertified Tax Accountant Act, Art. 33-2A statement recording the calculations, organization, and consultations behind a return may be attached to it
Pre-audit procedureCertified Tax Accountant Act, Arts. 34 & 35Where an attached statement exists, the accountant is given an opportunity to state views before an audit notice is issued

The attached-statement regime (Art. 33-2) is a mechanism for setting out, in advance, the basis for what is filed. Whether it is in place bears directly on transparency in ordinary times.

A Sense of the Costs (General Reference)

Fees vary with the scope of support. The following are ranges generally seen in the market.

CategoryReference fee (JPY)
Individual income tax return¥30,000–¥100,000 / year
Corporate monthly retainer¥20,000–¥50,000 / month
Corporate annual close¥150,000–¥300,000 / engagement
Inheritance tax return0.5%–1% of total estate
International tax consultation¥50,000–¥200,000 / engagement

Treat It as a Structure

The value of professional support is measured not by "how much cheaper it makes things" but by "whether there is a setup that can realize the proper tax burden, in conformity with the regimes, without omissions." Three things to confirm:

  • Is there a framework for considering applicable regimes in advance — the simplified regime, the blue-return special deduction, and so on?
  • Can it handle cross-border elements — the foreign tax credit, tax treaties, reporting regimes?
  • Is procedural transparency secured — authority to act as agent, the attached-statement regime?
