Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

beps-pillar-two-assessment scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

BEPS支柱二全球最低税评估

When To Use

  • 跨国集团合并收入超过7.5亿欧元
  • 集团在多个国家/地区有经营活动
  • 需要评估15%全球最低税的影响
  • 集团在低税率地区有实质性业务
  • 需要计算补足税(Top-up Tax)金额

Tools

  • 集团合并财务报表
  • 各实体单独财务报表
  • 各国有效税率计算数据
  • SBIE(实质所得排除)计算工具
  • OECD GloBE Model Rules及注释

Framework

一、GloBE规则概述

OECD支柱二全球反税基侵蚀(GloBE)规则于2021年12月发布,核心目标:

  • 最低税率:15%的有效税率
  • 适用范围:合并收入超过7.5亿欧元的跨国集团
  • 收入纳入规则(IIR):母公司所在国对低税率子公司征收补足税
  • 低税利润规则(UTPR):当IIR未适用时,其他成员国可征收补足税
  • 国内最低补足税(QDMTT):低税率国家可选择先行征收补足税

二、有效税率(ETR)计算

1. 管辖区ETR计算

$$ETR_{jurisdiction} = \frac{Adjusted Covered Taxes}{GloBE Income or Loss}$$

2. 调整后涵盖税款(Adjusted Covered Taxes)

包括:

  • 当期所得税费用
  • 基于GloBE收入或亏损调整的递延所得税
  • 符合条件的可退还税收抵免

排除:

  • 与排除收入相关的税收
  • 未分配CFC earnings的税收(非GloBE目的)
  • 第三方税款
3. GloBE收入或亏损

基于财务会计收入,进行以下调整:

  • 股息排除(部分或全部)
  • 资本利得排除(部分)
  • 政府补助调整
  • 关联公司权益法调整

三、补足税(Top-up Tax)计算

$$Top-up Tax = Top-up Tax Percentage \times Excess Profit$$

1. 补足税百分比

$$Top-up Tax Percentage = Max(0, 15% - ETR_{jurisdiction})$$

2. 超额利润

$$Excess Profit = GloBE Income - SBIE$$

3. 实质所得排除(SBIE)

$$SBIE = Payroll Carve-out + Tangible Asset Carve-out$$

  • 工资排除:5%(过渡期内可高达10%)× 符合条件的工资总额
  • 有形资产排除:5%(过渡期内可高达8%)× 符合条件的有形资产账面价值
  • 排除上限:不超过管辖区GloBE收入

四、收入纳入规则(IIR)

  • 适用主体:母公司(最终母公司或中间母公司)
  • 计算方式:母公司按持股比例计算子公司补足税
  • 分配规则:补足税分配至低税率管辖区
  • 合格UPE:最终母公司所在国如实施QDMTT,可优先适用

五、低税利润规则(UTPR)

  • 补充机制:当IIR未完全适用时启动
  • 分配方式:基于资产和收入在UTPR管辖区分配
  • 安全港:UTPR安全港(基于收入和员工)
  • 过渡UTPR安全港:2026年前适用

六、国内最低补足税(QDMTT)

  • 目的:允许低税率国家先行征收补足税
  • 优势:保留税收管辖权,避免IIR/UTPR征收
  • 要求:必须与GloBE规则一致
  • 中国考虑:如中国引入QDMTT,可优先征收

七、国际标准参考

  • OECD GloBE Model Rules(2021年12月)
  • OECD GloBE Commentary(2022年3月)
  • OECD Administrative Guidance(2023年2月、7月)
  • EU Minimum Tax Directive(Council Directive 2022/2523)

Workflow

  1. 确认集团是否达到7.5亿欧元收入门槛
  2. 识别集团在各管辖区的所有实体
  3. 收集各实体财务报表及税务数据
  4. 计算各管辖区ETR
  5. 计算SBIE
  6. 计算补足税金额
  7. 评估IIR/UTPR/QDMTT适用情况
  8. 提出优化建议
