Trump’s Plan to Eliminate Taxes on Social Security Forgets Your Children

President Donald Trump vowed to eliminate income taxes on Social Security benefits, a policy shift that experts warn would spell disaster for the welfare savings of the nation’s youngest, including those not yet born.

Slashing the income tax on Social Security would reduce revenues by $1.5 trillion over a decade and increase the federal debt by 7% by 2054, according to a study produced by the Penn Wharton Budget Model, a nonpartisan, research-based initiative at the University of Pennsylvania.

While nearly all retirees may see welfare gains, only the highest earners would gain more than $100,000 in remaining lifetime welfare. Yet, individuals under the age of 30, and those who have not yet been born, may face the largest losses — up to $22,000 over their lifetime.

That’s because eliminating taxes on Social Security benefits reduces incentives to save and work while increasing the federal debt, the analysis found. Average wages and GDP are also projected to fall over time.

Here’s what could happen if the Trump administration were to end taxes on Social Security today.

How Social Security is taxed

Before diving in, as you know, Social Security benefits are taxable based on your income, regardless of your age.

• Beneficiaries with a combined income below $25,000 ($32,000 for joint filers) pay no taxes on their benefits.
• Those with combined income between $25,000 and $34,000 ($32,000 and $44,000 for joint filers) are taxed up to 50% of their benefits.
• Those with combined income above $34,000 ($44,000 for joint filers) are taxed up to 85% of their benefits.

How exactly does that work?

About 85 cents of every Social Security tax dollar you pay goes toward a trust fund. Your tax dollars are used to pay monthly benefits to current retirees, their families, surviving spouses, and children of workers who have died.

According to the Social Security Administration (SSA), about 15 cents goes to a trust fund that pays benefits for people with disabilities and their families. Less than one penny out of every tax dollar is used by the SSA to manage the programs.

In short: the taxes you currently pay on Social Security aren’t held in a personal account for you to use when you get your benefits. As of January 2025, there are 68 million Social Security beneficiaries.

What are the Social Security trust funds?

Any tax dollars you pay that don’t go towards paying current beneficiaries are placed into the Social Security trust funds. These are managed by the U.S. Treasury Department and are tapped into to pay Social Security benefits, disability benefits, and administrative costs.

However, as it stands, that retirement trust fund is set to become insolvent by 2033. As reported by Kiplinger, Trump’s proposal to end taxes on Social Security benefits would speed up the program’s depletion by one year.

Once that happens, beneficiaries are expected to receive only 83% of their full benefits.

But the chance of Congress letting that happen is slim.

Ending taxes on Social Security benefits high-earners

If Trump were to eliminate taxes on Social Security benefits today, the biggest win would be for current retirees and the highest earners who are close to retirement.

• A 60-year-old in the highest three quintiles of gross income would see a welfare gain equal to a one-time payment ranging from $2,600 to $43,000 in their lifetime.
• By contrast, someone the same age who’s in the bottom 20th income bracket would see their welfare decrease by $2,400.
• At the same time, 50-year-old households in the top three income quintiles gain between $1,800 and $27,500.

Only the highest earning and eldest Millennials would benefit from ending taxes on Social Security benefits. Those in their 40s who belong to the top income brackets would see a welfare gain equal to a one-time payment of up to $12,400.

Meanwhile, anyone in their 40s within the 40th to 60th gross income bracket would see no gain at all.

Below that, any younger generation — no matter their income — would see a negative impact on their welfare.

Young adults and future generations are worse off

While more than 60% of current living households and over 95% of retirees would benefit from eliminating taxes on Social Security benefits, all future generations would be worse off.

• Those born today experience a welfare loss between $9,200 and $14,000.
• Unborn households face the largest losses, ranging from $11,700 to $22,000. This includes those born up to 20 years into the future.

As mentioned, the policy change reduces incentives to save for retirement and would lead to an increase in federal debt. According to the Penn Wharton study, this model does not encourage a higher labor supply which would result in declines in capital and wages over time.

The result is significant welfare losses, particularly for the youngest and unborn generations.

Retirees benefit, some more than others

As mentioned, while all retirees benefit from ending taxes on Social Security benefits the results would not be equal.

Higher-income retirees, who currently pay the most taxes on Social Security, gain between $11,000 and nearly $135,000. Meanwhile, households in the two lowest quintiles would see positive gains averaging between $1,000 and $2,000.

Social Security taxes: What’s next?

President Trump has reaffirmed his pledge to end taxes on Social Security benefits but has yet to offer concrete plans on how it would work. Any changes to Social Security would require an act of Congress with bipartisan support.

Being aware of how Social Security policy changes can impact your wallet, and that of future generations is more important than ever as you plan for retirement.

As mentioned, experts warn that cutting the tax on these benefits can cause millions of families to slip under the poverty line. While most retirees would see significant gains in welfare benefits, it wouldn’t be evenly distributed. Only the highest earners would see a notable difference.
