Role of a Tax Agent
A Tax Agent (Tax Administrator) is a person or legal entity located in Japan who is appointed to handle tax-related administrative matters on behalf of a taxpayer that does not have a residence or place of business in Japan. The role of a Tax Agent is strictly administrative in nature. It does not include tax advisory services or tax decision-making authority unless those services are separately engaged and performed by a licensed Japanese tax professional.
As a Tax Agent, we act as the taxpayer’s administrative interface with the Japanese tax authorities. Our role typically includes receiving official correspondence such as tax notices and assessment letters, submitting statutory filings prepared by the taxpayer or their tax advisor, arranging the payment of national and local taxes, and receiving tax refunds through a designated Japanese bank account. These services ensure that procedural requirements are satisfied and that communication with the tax authorities is handled smoothly and efficiently.
- Contact point with tax authorities
- Receipt of tax returns, notifications, and inquiry documents
- Submission of tax documents
- Management of tax payment and refund procedures
- Management of deadlines and administrative procedures
- Coordination of tax audits and inquiries
National and Local Tax Coverage
A Tax Agent does not assume the taxpayer’s tax liabilities. All tax obligations, penalties, and enforcement actions remain the sole responsibility of the taxpayer. If taxes remain unpaid, enforcement measures are taken against the taxpayer, not the Tax Agent. The Tax Agent bears no joint or secondary liability for the taxpayer’s obligations.
At the same time, preparing tax returns, responding to tax audits, or providing tax advice without proper licensing may constitute a violation of Japanese tax law. For this reason, careful separation of roles is essential in cross-border tax arrangements.
National Tax
- Corporate Tax
- Consumption Tax
- Withholding Income Tax
- Individual Income Tax
- Inheritance Tax
- Gift Tax
Local Tax
- Corporate Inhabitant Tax
- Business Tax
- Individual Inhabitant Tax
- Fixed Asset Tax
- Other Related Local Taxes
Services by Client Type
In principle, foreign corporations and non-residents who do not have an address, residence, or office in Japan are statutorily required to appoint a tax agent when conducting tax procedures such as tax returns, tax payments, and tax refunds in Japan.
Appointment is also required when a taxpayer relocates overseas but continues to have Japanese tax obligations, or when Japanese inheritance or gift tax matters arise involving heirs who reside outside Japan.
In cross-border situations, early appointment of a Tax Agent is strongly recommended to avoid procedural delays and unintended non-compliance.

Tax Agent vs Tax Representative
A Tax Agent under Japanese tax procedures acts as the taxpayer’s administrative contact in Japan. The preparation of tax returns, tax advice and professional representation before the tax authorities are separate services reserved for qualified Japanese tax professionals.
Mochizuki & Associates distinguishes the administrative role of a Tax Agent from the professional services performed by a licensed Japanese tax accountant and can provide both services within an integrated engagement where required.
