About this skill

Problem Space

When a business claims Hainan Free Trade Port incentives — such as 15% enterprise income tax, encouraged-industry treatment, or high-end/tight talent IIT relief — the hard part is proving that operations are substantive in the port. This skill helps teams audit common failure points: the four substantive-operation elements, in-port residence thresholds, revenue share, on-island accounts, and post-closure tax simplification. It is aimed at reducing exposure to shell-company, profit-shifting, and invoice-economy risks under regulatory review.

How It Works

  • Scenario-based Q&A: state the entity type — encouraged-industry company, branch, non-resident entity, or talent individual — and ask about eligibility, risk checks, or remediation.
  • Structured checks: evaluate operations in the port, personnel in the port, books in the port, and property in the port, then list gaps and policy references.
  • Risk flags: identify common issues such as insufficient resident staff, offshore settlement accounts, main business revenue below 60%, cost mismatches, or shell-company patterns.
  • Reports and estimation: generate self-assessment, revenue-share calculation, talent benefit checks, and landing-plan templates; a web self-check page supports real-time calculation and remediation hints, with data used only for the current calculation.

Boundaries

Outputs are compliance references only and do not constitute tax, audit, or legal advice. It does not file returns, pay taxes, process refunds, or handle disputes. For material decisions, confirm with the competent tax authority and qualified professionals.

Use Cases

  • Before a newly formed Hainan subsidiary claims 15% EIT for encouraged industries, verify the four substantive-operation elements.
  • Audit high-end and critical talent IIT relief by checking annual residence days, income thresholds, and employer substantive operations.
  • Assess a Hainan-registered entity with mainland settlement and business for shell-company, invoice-economy, and revenue-share risks.
  • After closure operation, review sales-tax simplification, incentive continuation, filing changes, and remediation items.

Best For

  • Corporate finance leads preparing Hainan subsidiary filings and incentive applications need to identify substantive-operation gaps.
  • Tax managers overseeing headquarters and branches need to confirm in-port books, accounts, and staff records are compliant.
  • HR or payroll owners handling high-end talent IIT relief need to verify residence days and income thresholds.
  • Advisors reviewing cross-border investment and profit structures need to flag shell-company, revenue-share, and closure-transition risks.
