Democrats' Social Security Plan Is a Tax on Paychecks, and the Numbers Say It Still Won't Close the Gap

Fresh off a midterm wave, Democrats are reaching for an old answer to Social Security's money problem: make high earners pay more. CNBC reported Sunday that Democrats campaigned on taxing high earners to shore up the program, and that the senior deduction passed last year is slated to expire in two years, setting up two big decisions for the new Congress.

The idea has a ready vehicle. Fortune reported that several of the Democrats just elected to the Senate, including Juliana Stratton of Illinois and Abdul El-Sayed of Michigan, want the payroll-tax cap raised or removed. Right now the Social Security tax applies only to the first $184,500 a worker earns in a year. Sen. Bernie Sanders' Social Security Expansion Act would apply the tax to wages above $250,000, eventually scrap the cap entirely, and raise benefits on top of it, according to Fortune.

It sounds simple: ask the wealthy to chip in and save Grandma's check. The numbers tell a harder story.

No one should pretend the program is fine. The 2026 Trustees Report projects that the retirement trust fund will run dry in late 2032, when an automatic cut of roughly 22 percent would hit retirees' checks, according to the Committee for a Responsible Federal Budget. Even if Congress merged the retirement and disability funds on paper, the combined reserves would be exhausted in 2034.

That is an emergency, and conservatives who believe this country must keep its word to the elderly should say so plainly. The question is whether a giant tax increase on work is the honest way to meet it.

Start with who actually pays. The payroll tax is a tax on paychecks. Scrapping the cap means the surgeon, the engineer and the owner of a growing plumbing company face a sharply higher rate on every dollar they earn above the line. The idea has drawn some Republican interest, too: the Tax Foundation's analysis looked at a proposal from Sen. Bernie Moreno, an Ohio Republican, and Sen. Elizabeth Warren to lift the cap. But the math does not change with the sponsor's party. The Tax Foundation describes lifting the cap as a 12.4-percentage-point tax increase on those earnings, and it estimates the change would shrink long-run economic output by 1.5 percent and cost about 1.8 million jobs.

Those are not abstract losses. The self-employed pay both the worker's and the employer's share, so the full increase lands on the same kitchen table where a family business keeps its books. Every dollar that goes to Washington is a dollar not spent hiring an apprentice, buying a second truck or saving for a child's tuition.

Here is the part campaign ads leave out. How much of the shortfall an uncapped tax would close depends on who is keeping score. Social Security's own actuaries put it at about 70 percent, while Congressional Budget Office accounting puts it closer to 45 percent, CRFB President Maya MacGuineas wrote. Part of the reason is the program's own design: higher taxed wages earn higher benefits. MacGuineas noted the actuaries' figure would rise to roughly 85 percent only if those added benefits were never paid.

So the plan would raise taxes on millions of paychecks and still leave a hole that Congress would have to fill some other way, most likely by coming back to the same workers for more. The Sanders version adds new benefits on top, which digs the hole deeper before it begins to fill it.

There is a second deadline. Last year's tax law gave Americans 65 and older an extra deduction of up to $6,000 each, or $12,000 for a married couple, phasing out for singles above $75,000 of income and couples above $150,000, according to the Peter G. Peterson Foundation. It runs through tax year 2028 and disappears after that unless Congress acts. The foundation also warns that the break adds to the national debt, especially if it is extended, a fair point that belongs in any honest debate.

Letting relief for seniors lapse while raising taxes on workers would squeeze both ends of the family at once: the grandparents on a fixed income and the parents paying the bills.

The warnings are already coming from budget watchdogs and free-market economists. CRFB cautions that the cap is no silver bullet, and the Tax Foundation has put a price on it in jobs and growth. Democrats take control in January, and with the 2032 date approaching, they will have to decide whether to chase a slogan or build a real bipartisan fix.

Scripture tells us to honor our fathers and mothers, and a nation honors that command partly by keeping its promises to them. Keeping faith also means telling the truth about the math. A lasting solution will need a growing economy, careful reforms that protect low-income retirees first, and a fair look at every part of the program, not one more tax on the Americans who get up early, work hard and sign the front of a paycheck.
