The integration of social security and individual income tax is an important concept in recent policy discussions in China, which means toSocial insurance payment datagivePersonal income tax declaration dataImplementing Information SystemsDocking, synchronization, sharing, and regulatory linkage

Simply put, it means:

How much tax should be paid on the declared salary income, and social security should also be paid based on this salary base, without "two sets of accounts".


📌 1、 What is' social security and individual income tax integration '?

✅ 定义:

社会保险申报系统give个人所得税系统整合并联动,使用人单位和个人在报税和缴纳社保时所使用的工资数据保持一致,从而实现税务与社保的并轨监管


🧩 二、背景原因

reasondescribe
📉 防止“低报工资基数”逃缴社保一些单位为了省钱,给员工高工资却按低工资交社保
📊 提高社保征管效率过去由社保局单独管理,数据不通,监管漏洞多
🧾 税务部门掌握真实收入数据税务局掌管个税系统,更易追踪工资真实性
💡 政策统一、精细化管理推动收入透明、规范用工,保障劳动者权益

🔄 三、并轨后的变化与影响

project并轨前并轨后(或并轨趋势)
报税工资比实际工资高或一致要和社保基数一致
社保基数很多单位故意低报必须与个税申报一致,否则异常
数据管理各自为政(社保 vs 税务)数据共享、比对自动化
检查机制被动抽查自动预警、系统比对、跨部门稽核
effect用人成本节约、员工保障差用人成本提升、员工保障增加

📌 四、谁受到最大影响?

对企业:

  • 过去“低报工资、高发津贴”操作将面临更大稽核风险

  • 用人成本增加(尤其是五险一金比例高的地区)

  • 劳务外包、人力派遣模式也将被更严格监管

对个人:

  • 优点:养老、医保等待遇将提升

  • 缺点:到手工资可能因社保基数提高而减少


🧮 五、举个例子:

某员工月薪为 20,000 元

  • 过去:公司按 6,000 元缴社保,按 20,000 报个税

  • 并轨后:系统比对发现不一致 → 税务稽查或补缴社保


✅ 六、并轨不是政策合并,而是数据合并

需注意,“并轨”并不等于“合并成一个税”:

  • 社保仍有其独立属性(养老、医保等缴费项目)

  • 个税仍由税法管辖

  • “并轨”指的是 信息共享、标准统一、协同征管


📌 七、政策趋势与展望

  • 多地已开展社保个税数据比对试点(如北京、深圳、上海)

  • 国家层面正在推动全国统一的“用工数据平台”

  • 长远来看,有助于打击逃税避保、保障职工权益、规范市场竞争
