There is a coordinated retirement income approach used by financially sophisticated retirees that gets minimal attention in financial media and that many advisors do not proactively explain. It involves deliberately drawing down personal savings earlier in retirement in order to secure a significantly larger Social Security check later.
The bridge strategy begins with a choice to delay Social Security to age 70, where the monthly benefit is fully maximized. During the years between retirement and age 70, the retiree funds living expenses by drawing from their 401(k), individual retirement account (IRA), or other investment accounts. The portfolio acts as the bridge a temporary income source that carries the retiree until the larger Social Security payment begins. The strategy is not about depleting savings. It is about deciding which income source to use first and recognizing that Social Security's guaranteed 8 percent annual increase for each year of delay between 67 and 70 is a specific, risk-free return that no investment vehicle reliably replicates. The Numbers in Practice The research underlying this article illustrates the mechanics with a specific scenario: a retiree with an $800,000 portfolio and $60,000 in annual spending needs. Scenario Social Security Annual Portfolio **Portfolio Income Withdrawal Withdrawal After Age 70** Claim at 62 $22,500/year $37,500/year $37,500/year (for life) Bridge to 70 $0 (ages 6269) $60,000/year $20,400/year (age (ages 6269) 70+) The bridge strategy costs more from the portfolio in the short term $60,000 per year during the delay period versus $37,500. But by age 70, Social Security pays $39,600 annually, reducing the required portfolio withdrawal to $20,400. From that point forward, the retiree's dependence on the portfolio is cut nearly in half. The long-term arithmetic favors the bridge strategy for retirees with sufficient assets and longevity. The short-term cost is real and requires a portfolio capable of funding the gap.
The bridge strategy addresses one of the most significant structural risks in retirement finance. Sequence of returns risk is the danger that a market downturn early in retirement when the portfolio is at its largest and withdrawals have just begun will permanently impair the portfolio's ability to sustain income for a full retirement. The mathematics of sequence risk are not intuitive. A 30 percent market loss in year two of a 30-year retirement does not look the same as a 30 percent loss in year twenty-five. The early loss depletes principal that would otherwise have decades to recover. Withdrawals taken during a downturn lock in losses by converting declining paper assets into spent cash. The bridge strategy reduces this vulnerability in the second half of retirement precisely when it matters most. By establishing a large Social Security floor at age 70, the retiree enters their 80s with a guaranteed income base that requires less from the portfolio. Smaller required withdrawals mean less forced selling during any future downturn. The portfolio has more room to recover. **The bridge strategy does not eliminate sequence of returns risk. It reduces the long-term portfolio dependence that makes that risk so destructive in the final decades of retirement.*** The Tax Optimization Window The years between retirement and age 70 before Social Security begins and before Required Minimum Distributions kick in at age 73 represent a period that tax planners call the gap years. For retirees who have stopped earning employment income, taxable income typically drops significantly. This creates a window for a specific tax maneuver: the Roth conversion. A Roth conversion involves moving money from a traditional IRA or 401(k) where future withdrawals will be taxed as ordinary income into a Roth IRA, where future growth and withdrawals are tax-free. The conversion itself is a taxable event in the year it occurs. But at the lower tax rates available during the gap years, the cost of that conversion is less than it would be later, when Social Security income, Required Minimum Distributions, and other sources stack together to push the tax bracket higher. The bridge strategy creates the natural conditions for this maneuver. The retiree is already drawing from a traditional IRA to fund living expenses. Converting additional amounts during those years to fill lower federal tax brackets costs less in current taxes than deferring the conversion to a higher-income year.
Required Minimum Distributions the mandatory annual withdrawals the IRS requires from traditional retirement accounts starting at age 73 are calculated as a percentage of the account balance. A larger account balance at 73 produces larger mandatory withdrawals and a higher annual tax bill. By drawing down traditional IRA or 401(k) balances during the bridge years, retirees reduce the account balance that will be subject to RMD calculations at 73. In some cases, this can keep income below the thresholds that trigger Medicare income surcharges formally called Income-Related Monthly Adjustment Amounts (IRMAA). IRMAA surcharges apply to Medicare Parts B and D premiums when modified adjusted gross income exceeds certain thresholds, which were $106,000 for single filers and $212,000 for married filers in 2025. THREE PROBLEMS, ONE STRATEGY The bridge strategy is unusual in retirement planning because it addresses three distinct financial objectives simultaneously: 1. Social Security maximization Delays claiming to lock in the highest possible monthly benefit and the largest possible COLA base. 2. Sequence of returns protection Reduces long-term portfolio dependency, limiting forced selling during future market downturns in the retiree's 80s and 90s. 3. Tax optimization Creates gap-year conditions for Roth conversions at lower rates and reduces future Required Minimum Distributions. Most retirement strategies address one of these. The bridge strategy addresses all three.
The bridge strategy has real prerequisites. It requires sufficient savings to fund living expenses without Social Security income for multiple years. It requires the financial discipline to follow a structured withdrawal plan. And it requires reasonable confidence in longevity if a retiree has serious health concerns or a family history that suggests a shorter lifespan, the breakeven age for delayed claiming may not be achievable. For retirees who satisfy those conditions adequate assets, a long expected time horizon, and the ability to optimize taxes during the delay period the bridge strategy integrates multiple objectives into a single coordinated approach. The strategy also has implications for surviving spouses. The Social Security benefit locked in at age 70 becomes the survivor's benefit if the higher earner dies first. Maximizing that figure through the bridge strategy means the survivor inherits the largest possible guaranteed income at the point when they are most likely to be living alone, potentially for another decade or more.
