Corporate Income Tax Check Skill

Overview

Calculate enterprise income tax (企业所得税) with automatic preferential rate detection, then run a compliance check and generate an actionable summary.

Use tools for all numeric computations — never guess tax amounts.

Workflow

Step 1: Identify Enterprise Type

Ask the user or infer from context:

Step 2: Get Taxable Income

Option A — User provides the taxable income directly → proceed to Step 3. Option B — User wants to calculate from financials → call query_user_financial_data:

{
  "user_id": "<from context>",
  "tenant_id": "<from context>",
  "fiscal_year": <year or null>
}

Extract taxable_income and corporate_tax_rate from the result.

Step 3: Calculate Tax

Call tax_calculator with tax_type="corporate_income_tax":

{
  "tax_type": "corporate_income_tax",
  "taxable_income": <value>,
  "tax_rate": <applicable rate>,
  "tenant_id": "<tenant_id>"
}

Or calculate_tax for more detailed small-enterprise logic:

{
  "tax_type": "corporate_income",
  "taxable_amount": <value>,
  "tax_rate": 0.25,
  "is_small_enterprise": <true/false>
}

Step 4: Compliance Check

Always call tax_compliance_checker to catch issues:

{
  "tax_data": {
    "corporate_tax": {
      "rate": <applied_rate>,
      "income": <taxable_income>
    }
  },
  "tenant_id": "<tenant_id>"
}

Error Handling

• No financial data in DB → ask user to provide taxable income manually or use financial-data-entry skill first.
• Taxable income is negative (亏损) → inform user: "本期亏损可在未来5年内弥补，无需缴纳企业所得税。"

Gotchas

• 小型微利企业优惠：应纳税所得额≤300万时适用5%，超过部分仍按25%（非一刀切）。
• 高新技术企业需持有认定证书，每三年重新认定。提示用户核实资质有效期。
• 研发费用加计扣除最高100%，若用户未提及，主动询问是否有研发支出。
