Counting the employer match changes the 401(k) fairness math

An American Retirement Association study released Tuesday puts a hard number on the center of the 401(k) tax-fairness fight: households earning $50,000 to $100,000 pay 9.1 percent of all federal income taxes yet receive more than 30 percent of retirement tax benefits, once the calculation includes employer contributions and tax-deferred growth. The paper, Hidden in Plain Sight, folds those two features into its definition of the tax benefit, and the definition changes the conclusion.

Low-income workers, by that math, receive almost eight times as much in retirement tax benefits as they pay in federal income taxes, and households under $100,000 together collect nearly 53 percent of the combined tax advantage from defined contribution plans. Filers above $200,000, who pay 71.4 percent of all federal income taxes, receive only 16.7 percent of the benefits, a ratio that does not favor the bracket that dominates federal income tax collection.

These ratios follow from the ARA's chosen baseline: it measures benefits against the federal income tax each group actually pays rather than against balances or wages, which turns a modest tax preference for middle-income households into a large relative number because their federal tax bills are small. High earners, who pay more than seven of every ten dollars of federal income tax, make the same benefit look small beside their burden. An absolute-dollar accounting would likely rank the groups differently, a point the ARA does not contest—its claim is about where the preference matters most, not who holds the largest balances.

Brian Graff, the ARA's chief executive, made the political argument in a LinkedIn post after the release: because the employer match is part of the calculation, working-class Americans receive the largest share of plan tax benefits, and many experts have the story wrong. The study goes further and recommends that the tax advantages of defined contribution plans be encouraged and protected.

Graff also pointed to the SAVERS Match taking effect in 2027, arguing that the gap between the perceived and actual benefits of retirement tax preferences will widen once the federal government begins paying into low- and moderate-income accounts. The warning is political rather than an accounting projection, but it names the risk behind the study: if the fairness debate keeps fixating on high earners sheltering income, the remedies Congress chooses may land on the contributions and matches the ARA says are helping households under $100,000.

There is room to dispute the ARA's chosen baseline, and the study is best read as advocacy rather than official scorekeeping, but the advocacy is transparent about what it includes: the employer match and tax-deferred growth are both treated as retirement tax benefits, and those deliberate choices make the old one-line critique of the 401(k) harder to sustain. The sharpest question that follows is whether the employer match sits inside or outside the federal tax benefit; the ARA says inside, and once it is inside, the distribution tilts downward, which means a policymaker who wants to argue the system still favors the affluent now has to say whether the match should be excluded and why—an exclusion that would restore the familiar caricature but ignore the contribution most workers actually rely on.

The study's warning about unintended consequences is the right one for the legislative debate ahead: if Congress treats 401(k) tax expenditures as a handout to the wealthy, it will aim at the deduction and may hit the match as well, reducing precisely the benefit the ARA's data says is flowing to moderate-income households. The more useful fight is over how the match should be designed, how much of it should be encouraged, and whether the SAVERS Match should be layered on top of it.

Whatever happens next, Hidden in Plain Sight has moved the argument—it is no longer enough to dismiss the 401(k) tax preference as a rich person's deduction, because the employer match now has to be counted, defended, or excluded with an explanation. That is the real test for the next tax bill, and it is a better test than the one the debate has been fighting.
