National pension's 30% survivor benefit overlap rate trails civil servant pension, sparking equity debate

The vast majority of national pension recipients entitled to both their own pension and a deceased spouse's survivor benefit are choosing their own old-age pension. The trend has become pronounced since a 2007 legal reform introduced a dual-payment adjustment system allowing those who opt for the old-age pension to receive an additional 30 percent of the survivor benefit on top.

Yet concerns over fairness persist. A recipient who chooses the survivor benefit receives nothing from their own old-age pension, and the 30 percent overlap rate remains lower than the 50 percent applied under the civil servant pension and other occupational pension schemes.

A report published Saturday in the monthly "Pension Issues & Trend Analysis" (No. 121) by the National Pension Research Institute analyzed cases of overlapping national pension entitlements from 2000 to 2025 and found that benefit-selection patterns shifted markedly after the 2007 reform.

The national pension system generally requires a recipient to choose only one benefit when entitlement to two or more pensions arises simultaneously. The 2007 reform allowed those who chose the old-age or disability pension to receive an additional 20 percent of the foregone survivor benefit. That overlap rate was raised to 30 percent in 2016.

Following those changes, the share of recipients choosing the old-age pension — among those who had been receiving a survivor benefit when old-age entitlement arose — climbed from 60 to 70 percent before 2007 to more than 90 percent afterward. Among those already receiving an old-age pension when a survivor benefit became available, the rate choosing to keep the old-age pension rose from 50 to 60 percent before 2007 to around 75 percent after.

Structural concerns remain, however. Under current rules, a recipient who opts for their own old-age pension receives an additional 30 percent of the survivor benefit. The reverse does not apply: anyone whose deceased spouse's survivor benefit is substantially larger and who therefore chooses the survivor benefit receives nothing from their own old-age pension.

The national pension's 30 percent overlap rate also trails the 50 percent rate applied under the civil servant pension and other occupational pension systems, fueling ongoing calls for reform on equity grounds.

The report said that as long as the current system structure remains in place, benefit-selection patterns are unlikely to change significantly, but noted that future shifts in pension system maturity or amendments to related laws could alter how recipients make their choices.
