《保险研究》20240505-《个人养老金递延纳税优惠政策研究》（谢家珍、陈柳）

［摘   要］我国人口老龄化程度不断加深，推动发展与基本养老保险、企业(职业)年金相衔接的第三支柱养老保险，有利于健全多层次、多支柱养老保险体系。本文通过构建个人养老金精算模型和运用数值模拟的方法，结合个人养老金递延纳税优惠政策，基于不同收入水平，测算缴费阶段限额标准、领取阶段税率对个人养老金替代率的影响。研究表明，在不同收入水平下，缴费阶段限额标准的提高并不能提升个人养老金替代率，但扩大了个人养老金替代率维持在某一定值的个人可支配收入区间，一定程度上保证了不同收入群体退休后生活水平的稳定；领取阶段税率的降低能够提升个人养老金替代率，但增幅并不明显。未来个人养老金政策动态调整时，需要认真考量税率的降低对个人养老金替代率的影响程度。

A Research on the Deferred Tax Preferential Policies for Third Pillar Personal Pension

XIE Jia-zhen,CHEN Liu

Abstract：China is facing the continuous deepening of population aging.Promoting the development of the third pillar pension insurance that connects with basic old-age insurance and enterprise (occupational) annuity is conducive to improving the multi-level and multi-pillar pension insurance system.Constructing an actuarial model of personal pension and taking into consideration of the deferred tax preferential policy for personal pension,this paper uses the numerical simulation method to measure the impact of contribution ceilings at the contribution stage and tax rates at the payout stage on the replacement rate of personal pension,based on different income levels.The research has shown that under different income levels,the increase in the contribution ceiling at the contribution stage does not improve the replacement rate of personal pension,but expands the range of personal disposable income where the personal pension replacement rate remains at a certain value,can,to some extent,ensure the stability of the life quality of retirees of different income groups;and the reduction of tax rates during the payout stage can increase the replacement rate of personal pension,but the increase is not significant.When adjusting personal pension policies dynamically in the future,it is necessary to carefully consider the impact of tax rate reduction on the replacement rate of personal pension.
