Pitfalls and rejection causes

• • 出入国記録の欠落は滞在日数の立証力を弱めます。
• • 証明は年度単位のため、複数年度分は個別申請が必要です。
• • 原文と訳文の金額・年度は完全一致させてください。

Tips from our team

• • 納税証憑は毎年アーカイブしておくと安全です。
• • 相手国指定の様式の有無を事前確認してください。
• • 翻訳と認証の期間を見込んでください。

• Check for sector-specific licences

  Some activities need a licence from a specialist regulator before operating. Verify at the planning stage.

• Fix the structure before registration

  Shareholding, objectives and required licences should be settled before filing; later changes require amendment filings and extra time.

• Use bilingual contracts with a governing version

  Cross-border contracts should state which language version prevails and how disputes are resolved.

• Assess tax residence before planning

  Liability depends on tax residence and any applicable double-tax agreement; evaluate before moving funds or receiving cross-border income.

• Improper nominee shareholding

  Using nominees to bypass foreign business restrictions carries serious legal risk. Structure the company lawfully from the outset.

• Wills that ignore cross-border assets

  Assets in different countries may fall under different succession rules; ensure multiple wills do not contradict each other.

• Late statutory or tax filings

  Late filing triggers statutory surcharges and penalties and can affect renewal of foreign executives' work permits.

• Outdated company certificates

  Certificates submitted should be freshly issued and consistent with the current register, or the receiving authority will refuse them.
