연금보험료 공제방식별 세부담의 차이와 개선방안

As Korea enters the super－aged society, it is very critical time now to prepare for old age pension. In line with such a social environment, Korea has consistently maintained a tax system support expansion direction for pension. In the revised Tax Law in 2013, the deduction type of pension premium changed from income deduction to tax credit (deduction). The reason is that high income brackets receive relatively bigger tax benefits than low income brackets, which causes inequity in taxation. The shift into tax credit type on general insurance premiums and other special deduction items has brought about the enhancement of taxation equity effect by income level. However, pension premiums have not shown a consistent result. Based on this, this study analyzed tax burden differences by earned income earners’ income level according to shift into pension premium credit type, and presented problems and improvement measures. This study presented several improvement measures as follows: first, re－shift into income deduction type to be in line with international pension credit type, to solve duplicate taxation, and to ease tax administrative complexity. second, credit type’s unification by pension type to reduce the complexity of double deduction type and for easy tax amount calculation and reduction of tax payment cooperation cost. third, introduction of negative pension tax credit in order to induce to join pension savings and enhance the expansion effect. fourth, income level adjustment through differential application of the credit rate of pension contributions.
