The Account That’s Better Than It Looks

When the One Big Beautiful Bill Act created Trump Accounts in July 2025, most coverage focused on the $1,000 government seed contribution for newborns and the basic structure of a new tax-deferred savings account for children. The general reaction was positive but measured: a nice start, a useful nudge toward investing, a modest benefit for families who sign up.

Then the Wall Street Journal’s Ashlea Ebeling reported on something that changed the conversation entirely. A strategy — outlined in a March 2026 article — showed that Trump Accounts are not just a modest savings vehicle. In the right hands, used with a specific and deliberate technique, they are potentially the most powerful intergenerational wealth-building tool created in a generation.

The strategy is sometimes called “the hack.” It has three components: contribute the maximum $5,000 per year for 18 years, then convert the account to a Roth IRA at the right moment, and let compound interest do the rest for 40 or 50 more years. If executed correctly, the result is a tax-free retirement fund worth several million dollars — built from $90,000 in total contributions.

This blog post explains that strategy in full: how it works, what the numbers actually look like, what the risks are, and who it is and is not right for.

How Trump Accounts Work: A Quick Recap

Trump Accounts (formally Section 530A accounts under the Internal Revenue Code) are tax-deferred investment accounts for children under 18 created by the OBBBA. Key rules:

• Any child under 18 with a Social Security number can have an account.
• Contributions of up to $5,000 per year (indexed for inflation after 2027) can come from parents, grandparents, family friends, and other individuals.
• Employers may contribute up to $2,500 per year per employee, which counts toward the $5,000 cap and is not taxable to the employee.
• All contributions are made with after-tax dollars — there is no deduction for the contributor.
• Funds must be invested in low-cost mutual funds or ETFs tracking the S&P 500 or another broad US equity index. Expense ratios must be at or below 0.10%.
• No withdrawals are permitted before the end of the year prior to the child’s 18th birthday (the “growth period”).
• Children born between 2025 and 2028 receive a one-time $1,000 federal seed contribution if an election is made on their behalf.
• At age 18, the account converts to a traditional IRA and follows standard IRA rules.
• Accounts go live July 4, 2026. Parents can sign up now at TrumpAccounts.gov or via IRS Form 4547 with their 2025 tax return.

Important: Only private contributions (from parents, grandparents, the child, etc.) create “basis” in the account. The government’s $1,000 seed money, employer contributions, and charitable contributions do NOT create basis and are fully taxable upon withdrawal or conversion.

The Hack Explained: Step by Step

Here is the strategy in its cleanest form, as described by financial planners and the Wall Street Journal article that gave it its name.

Step 1: Contribute the Maximum, Every Year, Starting at Birth

Contribute $5,000 per year to the Trump Account from the year the child is born through age 17 — 18 years of contributions, totalling $90,000 out of pocket. The money is invested in a low-cost S&P 500 index fund inside the account and compounds tax-deferred throughout childhood.
Step 2: At Age 18, the Account Converts to a Traditional IRA
When the child reaches 18, the Trump Account automatically transitions to a traditional IRA. At this point, the account holds both (a) after-tax basis — the $90,000 in contributions you made with post-tax dollars, which is not taxed again — and (b) pre-tax earnings — the investment growth, which has never been taxed and is taxable upon distribution or conversion.

Step 3: Convert the Traditional IRA to a Roth IRA

The key move is here. The young adult — ideally in the early college years when their income is at its lifetime low — converts the traditional IRA to a Roth IRA. A Roth conversion is a taxable event: you pay ordinary income tax on the pre-tax (earnings) portion of the account in the year of conversion. But once inside the Roth, all future growth is completely tax-free, and qualified withdrawals after age 59½ are tax-free.
The beauty of the pro rata rule working in the family’s favour here is that contributions were after-tax. In a typical account where $90,000 was contributed and the account has grown to, say, $278,000, approximately 60% of every dollar converted is basis (not taxed) and only 40% is taxable earnings. The tax bill on conversion is therefore smaller than it would appear on first inspection.

Step 4: Let the Roth Compound for 40–50 Years

Once the conversion is complete, the Roth IRA grows entirely tax-free. No annual taxes on dividends or capital gains. No required minimum distributions (RMDs) during the owner’s lifetime. Tax-free withdrawals from age 59½ onward. The account’s value at retirement depends on contributions, returns, and time — but the projections are striking.

WSJ’s core finding: The real power play is for parents to contribute $5,000 a year for 18 years, then help their child convert the account to a Roth IRA so that it can ultimately be accessed tax-free and penalty-free. — Wall Street Journal, March 2026

The Numbers: What $90,000 Can Become

The projections for this strategy depend on the assumed rate of return and how long the Roth is left to compound. The S&P 500 has historically averaged approximately 10% nominal annual returns over the long term (though past performance does not guarantee future results). These are illustrative projections only.

Scenario	Account Value at Age 18	Projected Value at Age 65
$1,000 seed only, no further contributions (7% return)	~$5,560	~$70,000+
$5,000/yr × 18 years (7% return), then Roth conversion	~$278,000	~$3,000,000+
$5,000/yr × 18 years (8% return), then Roth conversion	~$299,000	~$5,000,000+
$5,000/yr × 18 years (10% return), then Roth conversion	~$255,000–$290,000	~$7.5M–$8.8M

To understand the scale of what the Roth conversion unlocks: attorney and financial planner Mat Sorensen describes a scenario where $100,000 in a Trump Account is fully converted to a Roth at age 18. With no additional contributions, invested for 45 years at 10% annual returns, that sum grows to approximately $8.8 million by age 65 — every dollar of it tax-free. The same $100,000 left in a traditional IRA would grow to the same $8.8 million — but millions of dollars would be owed to the IRS and applicable state tax authorities upon withdrawal.

Mercer Advisors modelled a slightly more conservative scenario: a child born in 2026 whose parents contribute $5,000 per year for 18 years, convert to Roth, and assume an 8% annual return. By age 65, the account could reach approximately $7.5 million — all tax-free. The total out-of-pocket cost to the parents: $90,000 over 18 years.

Even the more modest 7% return scenario — which assumes returns below the S&P 500’s long-term average — projects an account value at retirement of over $3 million from that same $90,000 investment. The variable is not the math; it is the discipline to contribute consistently, the timing of the conversion, and the availability of outside funds to pay the conversion tax.

The Pro Rata Rule and Why Taxes Are Smaller Than You Think

The most common objection to the Roth conversion strategy is the tax bill at conversion. It is real — but it is smaller than it first appears, for a reason that is embedded in the structure of Trump Account contributions.

Because contributions to Trump Accounts are made with after-tax dollars (there is no deduction), they create “basis” in the account. When you convert to a Roth, the IRS applies the pro rata rule: for every dollar converted, the taxable and non-taxable portions are proportional to the ratio of earnings to total contributions. Only the earnings are taxable; the original contributions are not.

Example: If a child’s Trump Account holds $90,000 in contributions (basis) and has grown to $150,000 total, the basis percentage is 60%. Every dollar converted is 60 cents not taxed and 40 cents taxed as ordinary income. The family is not paying tax on the full $150,000 — only on the $60,000 in earnings.

The optimal conversion strategy, detailed by TrumpAccounts.guide and other planning resources, is to spread the conversion over two to four college years while the young adult’s income is minimal. During those years, if the taxable portion of the conversion stays within or below the standard deduction ($16,100 for a single filer in 2026), the federal tax on the conversion can be zero. Planning to pay any remaining conversion tax from outside the account — rather than from the account itself — preserves the full balance for continued compounding.

Key insight: If a child has no other income during their college years, they may be able to convert up to approximately $37,500 per year (at a 40% taxable ratio) without owing any federal income tax — converting the entire account over 2–4 years at zero or near-zero federal cost.

The Kiddie Tax Trap: The Risk Nobody Talks About

The single most important warning in this strategy is one that many headlines about the “hack” have glossed over: the kiddie tax.
The kiddie tax is a provision of the US tax code that taxes a child’s unearned income (including income from a Roth conversion) at the parents’ marginal tax rate, rather than the child’s much lower rate. It applies to children under 19, and to full-time students under age 24 who have not reached financial independence.

If a child converts their Trump Account to a Roth IRA at age 18 while still in college, and they are classified as a “kiddie tax” subject under IRS rules, the conversion income could be taxed at the parent’s rate — which might be 22%, 24%, or even 32% — rather than the child’s 0% or 10% rate. The entire premise of the strategy — converting at a low tax cost — collapses if the kiddie tax applies.

The solution, recommended by multiple financial planners in practice, is to wait until the child is 24 or older and fully financially independent before executing the Roth conversion. Yes, this means a few more years of tax-deferred growth rather than tax-free growth — but the dramatically lower conversion tax rate more than compensates for the delay. Alternatively, some families plan to execute the conversion after the child takes a gap year, starts work, or otherwise establishes independent income, timing it to a year when their earned income pushes them out of kiddie-tax territory but their overall income remains low.

Warning: Converting a Trump Account to Roth while the beneficiary is a full-time student under age 24 may trigger the kiddie tax, taxing conversion income at the parents’ higher rate. Always consult a tax professional before executing a Roth conversion.

Is This Strategy Right for Every Family?

The Trump Account Roth conversion strategy is compelling, but it is not universally applicable. It works best for families who:

• Can consistently contribute $5,000 per year per child for 18 years without sacrificing their own retirement savings or emergency fund.
• Have the ability to pay any conversion tax from outside the account when the time comes, preserving the full balance for compounding.
• Have children young enough to benefit from the full 18-year growth period and then decades of Roth compounding afterward.
• Are comfortable with the constraints of the Trump Account structure during the growth period, including locked funds and index-fund-only investing.

It is less suitable for families who:

• Are not yet maximising their own retirement accounts. Financial planners consistently recommend securing your own retirement first. A parent who contributes $5,000 to a child’s Trump Account instead of their own 401(k) may be trading a current-year tax deduction and potential employer match for a benefit their child will access in 50 years.
• Need the flexibility of accessible savings. Trump Account funds are locked until the child turns 18 — unlike a 529, which can be used for education, or a taxable brokerage, which can be accessed anytime.
• Are primarily focused on college funding. For education savings, 529 plans remain the more tax-efficient vehicle: qualified withdrawals are tax-free rather than taxed as ordinary income.

The Center for Retirement Research at Boston College recommends viewing Trump Accounts not as a replacement for other savings tools but as a complement — “Used thoughtfully alongside 529 plans and IRAs, they may offer a meaningful head start on long-term financial security.”

Conclusion

The “hack” at the heart of this strategy is not actually a loophole or a workaround. It is the intended logic of a well-designed financial structure: contributions made with after-tax dollars create basis, basis is not taxed again on Roth conversion, and Roth accounts grow and distribute tax-free for life. Trump Accounts, by allowing contributions from birth before earned income exists, simply extend the timeline over which this compounding can operate. That extension, over 40 to 50 years, is what transforms $90,000 in contributions into a multimillion-dollar tax-free retirement fund.

The numbers are real. The strategy is sound. The risks — primarily the kiddie tax and the opportunity cost relative to the parents’ own retirement savings — are manageable with proper timing and professional guidance. And the upside, for a family that executes it with discipline and patience, is genuinely historic: the possibility of giving a newborn child a guaranteed multimillion-dollar head start on financial independence, built from consistent small contributions over 18 years.
As certified financial planner Ryan Greiser put it: “You’re giving a child a head start on tax-advantaged compounding. In investing, the biggest advantage isn’t picking the perfect stock — it’s starting early and staying consistent.” With Trump Accounts, for the first time, “starting early” means starting at birth. For families who can use them, that is an extraordinary gift.

Frequently Asked Questions

What is the Trump Account Roth conversion hack?

The strategy involves contributing the maximum $5,000 per year to a Trump Account for 18 years ($90,000 total), then converting the resulting traditional IRA to a Roth IRA when the child is in their early-to-mid-20s and in a low tax bracket. Once inside the Roth, the money compounds tax-free for 40–50 years, potentially reaching several million dollars by retirement.

How much can a Trump Account grow by retirement?

Projections vary by assumed rate of return. At 7% annual returns with $5,000/year contributions for 18 years and a Roth conversion, the account could exceed $3 million by age 65. At 8%, projections reach $5–7.5 million. At 10% (the S&P 500’s long-term historical average), some models project $7.5 to $8.8 million. All are illustrative and not guaranteed.

Will I owe taxes when converting a Trump Account to a Roth IRA?

Yes, on the earnings portion only. Because Trump Account contributions are made with after-tax dollars, they create basis that is not taxed again. The IRS pro rata rule applies: the taxable percentage equals the earnings as a proportion of total account value. If contributions represent 60% of the account, only 40% of each converted dollar is taxable. With careful planning during low-income college years, the total tax on conversion can be modest or even zero.

What is the kiddie tax and why does it matter here?

The kiddie tax applies unearned income of children under 19 (and full-time students under 24) at the parents’ marginal tax rate rather than the child’s lower rate. If a Roth conversion is executed while the child is a full-time student under 24, the conversion income could be taxed at the parents’ higher bracket, negating much of the strategy’s benefit. Most planners recommend waiting until the child is 24 or financially independent before converting.

Should parents contribute to a Trump Account before maxing out their own retirement?

Most financial planners say no. Your own retirement savings — particularly contributions that receive an employer match or a current-year tax deduction through a 401(k) — should come first. Trump Account contributions are a powerful wealth transfer tool, but they deliver their value to the child, not the parent. Secure your own financial foundation before funding a child’s account.

Does the government’s $1,000 seed money create basis?

No. Only private out-of-pocket contributions from parents, grandparents, the child, and other individuals create basis in the account. The government’s $1,000 pilot contribution, employer contributions, and charitable contributions do not create basis and are fully taxable upon Roth conversion or distribution.

Can the conversion tax be paid from outside the account?

Yes, and this is strongly recommended. If you pay the conversion tax from the account itself, you reduce the balance that benefits from tax-free Roth growth. Paying the tax from external funds preserves the full account value inside the Roth, maximising long-term compounding.

Is a Trump Account better than a Roth IRA for a child?

They serve different purposes. A custodial Roth IRA for a child requires earned income, which limits contributions during the early childhood years. A Trump Account has no earned income requirement, allowing $5,000/year contributions from birth. The strategy described in this article uses the Trump Account as a bridge — funding it from birth, then converting to a Roth at age 18 or later to achieve Roth’s tax-free growth advantages.

When do Trump Account contributions start?

Contributions cannot begin before July 4, 2026, when the platform launches. However, parents can already elect to receive the $1,000 pilot contribution for eligible children born in 2025–2028 by filing IRS Form 4547 with their 2025 tax return or at TrumpAccounts.gov.

Is Trump Account investing limited to the S&P 500?

Funds must be invested in low-cost mutual funds or ETFs tracking the S&P 500 or another broad US equity index, with an expense ratio at or below 0.10%. No individual stocks, bonds, sector funds, or alternative investments are allowed during the growth period.
