Last year, a reader wrote in responding to a prior column about whether Americans should claim Social Security early, citing widespread concerns about the program’s long-term solvency.
The reader referenced multiple reports suggesting Social Security could run out of money by 2032, a timeline that has prompted many Americans to consider claiming benefits as soon as they become eligible at age 62.
The original column featured a CPA who advised clients to take Social Security early, a position that sparked significant debate among readers who see the issue differently based on their own financial circumstances.
For high earners especially, the decision about when to claim Social Security is far more nuanced than simply grabbing benefits before potential funding shortfalls materialize.
The core question involves how income is generated, since different income streams carry very different tax treatments that can significantly affect a retiree’s overall financial picture.
Consider the basic math: a Social Security benefit of $2,000 a month at age 62, or $24,000 a year, compares against $3,500 a month at age 70, or $42,000 a year.
If a high earner claims at 62 and invests that $24,000 annually, the investment returns will likely generate taxable income, potentially increasing Medicare premiums and triggering the net investment income tax.
That surtax, known as the NIIT, is a 3.8% IRS charge applied specifically to high-income earners and represents a meaningful additional cost on top of ordinary income taxes.
Waiting until 70 flips this dynamic, because a larger Social Security benefit comes with built-in preferential tax treatment that investment income simply does not receive.
At the federal level, at least 15% of Social Security benefits are effectively tax-free for higher earners, since up to 85% of benefits are taxable, leaving a guaranteed tax-free slice regardless of income level.
The state-level advantage can be even more substantial, since many states exempt Social Security benefits entirely from state income tax, unlike most other forms of retirement income.
Delaying benefits until 70 means that the larger monthly payment may be shielded from state taxation, compounding the financial advantage for retirees living in those states.
When a retiree has less overall income in later years, a larger Social Security benefit means a bigger share of total income receives this preferential tax treatment, stretching each dollar further.
One reader captured the conclusion plainly and directly: “For that reason, I’ll happily wait.”
Importantly, the tax advantages of delaying Social Security apply even more powerfully to lower earners, who face a smaller tax burden overall and benefit even more from income that carries preferential treatment.
The solvency concern is real and worth monitoring, but for many higher earners, the combination of a larger benefit and favorable tax treatment makes waiting the more financially sound strategy.
