The impact of a retirement savings account cap

This Issue Brief provides an initial analysis of the potential financial impact on private-sector retirement benefits of the retirement savings account cap included in the Obama administration's FY 2014 budget proposal. It finds that although a very small percentage of current 401(k) participants with IRA accounts have combined balances sufficient to be immediately affected by the proposed limit, over time (and depending on the applicable discount rates, whether a defined benefit pension is involved, and the size of the 401(k) plan) the impact could be much greater. Simulation results for 401(k) participants assuming no defined benefit accruals and no job turnover show that more than 1 in 10 current 401(k) participants are likely to hit the proposed limit sometime prior to age 65, even at the current historically low discount rate of 4 percent. When the simulation is rerun with discount rate assumptions closer to historical averages, the percentage of 401(k) participants likely to be affected by these proposed limits increases substantially: For example, with an 8 percent discount rate, more than 20 percent of the 401(k) participants are simulated to reach the limit prior to retirement. When the impact of stylized, defined benefit account assumptions are added to the analysis, the percentage of 401(k) participants simulated to reach the proposed limits increases even more: In fact, for 401(k) participants assumed to be covered by a 2 percent, three-year, final-average plan with a subsidized early retirement at 62, nearly a third are assumed to be affected by the proposed limit at an 8 percent discount rate. Additional analysis is performed for small plans (those with less than 100 participants) to assess the potential impact of eventual plan terminations if an when the owners and/or key decision makers of the firms reach the cap threshold. Depending on plan size, this may involve as few as 18 percent of the firms (at a 4 percent discount rate) to as many as 75 percent of the firms (at an 8 percent discount rates).
