Market Context: AI-Driven Earnings Pushes S&P Higher
New research from Goldman Sachs peers suggests S&P 500 earnings will rise about 22% year over year in the second quarter, led by AI investment gains and stronger energy profits. The market has steadied this year, with the index up roughly 9% year-to-date and about 21% over the past 12 months. goldman says driving earnings has become a shorthand for investors watching profits swell as technology and energy pulse through corporate results.
Investors are weighing the strength of this earnings surge against higher rates, potential policy shifts, and the risk that valuations could reprice if AI-driven momentum slows. Still, the temperature of the rally remains supportive for broad stock exposure for now, especially among names tied to productivity gains and semis.
Retiree Dilemma: A 68-Year-Old With Pretax Wealth Faces a Tax-Heavy Road to 73
For a 68-year-old retiree with most savings sitting in traditional 401(K) plans or IRAs, the current earnings surge inside pretax accounts is a double-edged sword. Growth inside these accounts translates into larger required minimum distributions (RMDs) when withdrawals begin, and that higher balance compounds future tax bills.
Tax professionals note that RMDs are designed to tax pretax wealth as it comes out to be spent in retirement. The eye-opening part for an investor nearing 73 is how a bigger RMD can ripple through other parts of retirement finances, including Social Security taxation and Medicare premium surcharges.
As one tax-policy expert put it, the challenge is that a larger pretax balance at RMD time can push a retiree into higher marginal tax brackets as distributions start. The net effect is a bigger bite from federal taxes and, in some cases, state taxes as well when RMDs are counted as income.
Tax Tailwinds and Headwinds: What Can Change Your Path
Two tax levers loom large for someone turning 73 in a few short years: RMDs themselves and the way Social Security and Medicare costs interact with higher income. In some planning scenarios, up to 85% of Social Security benefits can become taxable for high earners, and Medicare IRMAA surcharges can rise markedly with income. In a concrete example, planners show that the IRMAA bill can swing into the hundreds of dollars each month for households with rising income from RMDs.

The takeaway is clear: a rising pretax balance is not just a paper gain; it translates into a future tax bill that compounds over time as distributions are taken and benefits are calculated. The prospect has led to a wave of retirement planning discussions focusing on how to credibly reduce the tax bite before 73 rolls around.
Planning Window: The Critical 5-Year Phase
Experts emphasize a five-year runway before age 73 as a crucial window to shape future taxes. Decisions made now—such as how much to withdraw, whether to convert to a Roth IRA, and how to time Social Security—can meaningfully lower the eventual RMD burden. A strategic mix of tax diversification and careful withdrawal sequencing can help contain the total tax bill without sacrificing essential income in retirement.
Strategies to Consider Now
- Roth conversions during favorable tax bouts: Converting a portion of traditional 401(K)/IRA balance to a Roth IRA in years with lower ordinary income can reduce future RMDs. Pro rata rules apply, so plan with a tax advisor to avoid unintended tax consequences.
- Gradual withdrawals to spread tax: Instead of a lump-sum withdrawal strategy, retirees may benefit from a steady withdrawal plan that keeps income in a lower tax bracket and minimizes spikes in RMDs.
- Tax diversification across accounts: A blend of taxable, tax-deferred, and tax-free accounts provides flexibility to manage taxable income in retirement.
- Qualified charitable distributions (QCDs): If charitably inclined, directing RMDs directly to charity via QCDs can reduce adjusted gross income and lower tax exposure.
- Social Security timing and Medicare planning: Delaying Social Security to maximize benefits can offset higher RMDs later, while understanding IRMAA rules helps keep health costs predictable.
In conversations with clients, some advisors reference a simple framework: use the five-year window to lower RMDs and smooth tax brackets through Roth conversions, while preserving enough liquidity to cover essential needs. The phrase goldman says driving earnings has become a shorthand for the current market environment, but on the tax side the real work is in careful distribution planning.
What This Means for Investors Today
The AI-driven earnings trend underpinning this year’s rally is not a blind bet. Investors should recognize that higher profits can bolster portfolio values, but the benefit inside pretax accounts can mask a looming tax bill that arrives with the first 401(K) or IRA withdrawal after 73. The combination of rising RMDs, taxable Social Security, and IRMAA surcharges creates a tax path that looks different from the last decade’s “grow and spend” playbook.
Market participants should watch how companies continue to deploy AI and how energy names contribute to earnings, as these factors will help sustain the broad market tone. Yet the tax consequences for retirees remind investors that earnings are not income—pulling money out in retirement is the real test of a portfolio’s staying power.
Bottom Line: Balancing Growth and Tax, With a Close Eye on 73
As the fiscal clock ticks toward age 73, retirees with traditional pretax wealth face a dual challenge: capture the earnings rally while managing the tax tail that follows withdrawals. The current environment, underscored by Goldman’s earnings outlook, reinforces the need for deliberate planning, not simply chasing rising balances. The right move for many is to build a tax-sensitive withdrawal plan now, and to consider Roth conversions and other strategies that may reduce the RMD tax hit at 73.
