Building Generational Wealth: The Math Behind Trump Accounts

Executive Summary for the Taxpayer: Trump Accounts are real traditional-IRA-type accounts created by the One Big Beautiful Bill Act and codified under IRC §530A, not merely a proposed investment concept. The model below shows what $5,000 contributed at the end of each year from birth through age 17 could become by age 65, but the results are pre-tax, nominal, fee-limited illustrations rather than guaranteed outcomes.

What a Trump Account Actually Is

A Trump Account is an individual retirement account established for an eligible child. During its growth period, the account follows special rules for contributions, investments, and distributions; after that period, traditional IRA rules generally apply. IRC §530A

The model in this article assumes:

• A contribution of $5,000 at the end of every year
• 18 contributions, from birth through the year the child turns 17
• Total out-of-pocket principal of $90,000
• No further contributions after age 18
• An additional 47 years of compounding, from age 18 through age 65
• No withdrawals unless specifically shown
• Annual return assumptions of 7%, 10.5%, and 15%

The growth period generally ends on December 31 of the year the beneficiary turns 17, and contributions are generally limited to $5,000 per year during that period. IRC §530A

Contributions are generally made with after-tax dollars. An eligible child may also receive a one-time government contribution under the separate contribution pilot program, which does not replace the annual contribution limit. Our related One Big Beautiful Bill Act guide discusses the broader legislation.

The Investment Rules Matter

During the growth period, Trump Account funds cannot simply be invested in any stock, cryptocurrency, bond, or actively managed fund. The funds must generally be invested in an eligible mutual fund or ETF that:

• Tracks a qualified index
• Does not use leverage
• Tracks an index composed primarily of U.S. companies
• Has annual fees and expenses of no more than 0.1 percent

The statute specifically recognizes the S&P 500 as a qualified index. The IRS has also issued proposed guidance addressing eligible investments, index tracking, leverage, monitoring, and fees. IRC §530A; 91 FR 54280

That makes S&P 500 return assumptions a reasonable illustration of what an eligible index investment could have returned. It does not mean the account is freely invested in the S&P 500, and it does not make any return predictable. The 0.1-percent fee ceiling is a genuine structural advantage, but it is not the same as having no costs.

Phase One: The Balance at Age 18

For a child whose contributions stop at 18, the $90,000 of total contributions produces the following balances:

• 7% historical baseline: $169,995
• 10.5% balanced middle case: $239,659
• 15% stress illustration: $379,182

The 7-percent figure is the number to use as the planning baseline in this article. The 10.5-percent case demonstrates how materially the result changes when the assumed return rises.

The 15-percent case is not a responsible long-term projection. Sustaining a 15-percent annual return for 65 years is highly improbable, and the figure is included only to show how sensitive compound-growth mathematics becomes when the assumed rate increases.

Phase Two: Age 18 Through Age 65

Once the contributions stop, the model leaves the account untouched for another 47 years. The comparison below carries the same assumptions through to age 65.

Return assumption	Balance at age 18	Age 65 with no withdrawal	Balance after $100,000 withdrawal at 18	Age 65 after withdrawal
7% historical baseline	$169,995	$4,087,654	$69,995	$1,683,083
10.5% balanced middle case	$239,659	$26,158,927	$139,659	$15,243,844
15% stress illustration	$379,182	$270,175,501	$279,182	$198,923,265

The withdrawal scenario assumes that $100,000 is taken immediately at age 18 and the remaining balance is never touched again. Under the 7-percent assumption, that withdrawal reduces the age-65 result from $4,087,654 to $1,683,083.

That is the cost of removing capital early: the account loses not only the $100,000 but also 47 years of potential compounding on that amount. The model does not establish that a $100,000 withdrawal would be tax-free or penalty-free.

Distributions are generally prohibited before the year the beneficiary turns 18. After the growth period, traditional IRA distribution rules generally apply, including possible ordinary income taxation and additional tax rules for early distributions. IRC §530A; IRC §§ 408(d), 72(t)

Time and Return Matter More Than the Contribution

The total principal in this model is $90,000. The important lesson is that the assumed rate matters far more than the difference between one contribution and another, while time gives the model its power.

At 7 percent, the $90,000 of principal becomes roughly 45 times itself by age 65. At 10.5 percent, the result is roughly 291 times the principal.

For perspective, the approximate multiple of original principal at age 65 is:

• 5%: approximately 15 times
• 7%: approximately 45 times
• 10%: approximately 223 times
• 15%: approximately 3,002 times

These multiples are not promises. They are reminders that a small change in an assumed annual return, repeated for decades, can overwhelm the original contribution amount.

What the Math Does Not Show

The model is useful, but it omits several realities that can change the result substantially:

• These are nominal, pre-tax figures. Inflation means a 2061 dollar is worth a fraction of a 2026 dollar, and a dollar received in the age-65 year of this model will have less purchasing power than a 2026 dollar.
• No fees, expense ratios, or advisory costs are deducted in the model. The eligible-investment fee cap of 0.1 percent limits this, but it is not zero. IRC §530A
• No tax drag is modeled because the account is assumed to remain invested during the accumulation years.
• Returns are not smooth. A 7-percent average delivered through a bad sequence of returns can produce a materially different result than a steady 7 percent every year.
• Nobody contributes $5,000 every single year without interruption for 18 years. Job loss, illness, and divorce happen.
• The model assumes the account is never touched, which is the hardest assumption in it.

The Tax Reality After the Growth Period

A Trump Account is a traditional-IRA-type account, not a Roth IRA. After the growth period, assets may be transferred to a traditional IRA, and ordinary traditional IRA rules generally apply to later distributions. IRC §530A

The figures above are therefore pre-tax balances. A $4,087,654 traditional account is not $4,087,654 of spendable, tax-free money. Future withdrawals may be included in ordinary income, and early distributions may raise additional tax issues. IRC §§ 408(d), 72(t)

There is no provision allowing a direct rollover of a Trump Account to a Roth IRA under the special Trump Account rules. After the growth period, a transfer to a traditional IRA may be considered; a Roth conversion could then be evaluated from that traditional IRA, with the converted taxable amount generally included in ordinary income. IRC §§ 530A, 408(d), 408A

The Kiddie Tax is not the central issue here. That rule generally addresses a child’s unearned income in taxable accounts, while a Trump Account is an IRA-type vehicle.

Retirement planning also has to account for required minimum distributions. Current law generally requires many traditional IRA owners to begin RMDs at age 73, while the SECURE 2.0 age-75 rule applies to younger cohorts beginning in 2033. IRC §401(a)(9); IRS Publication 590-B

Because a child born today reaches these ages decades from now, the age-75 rule is the one that will most likely govern this account, not age 73. Confirm the applicable age for the specific beneficiary when planning distributions. SECURE 2.0 Act §107; IRS Publication 590-B

Large traditional IRA distributions can also affect how much Social Security benefits are taxable under IRC §86 and can increase Medicare Part B and Part D premiums through IRMAA, which generally uses tax information from two years earlier. IRC §86; SSA Medicare premiums

Frequently Asked Questions

What is a Trump Account?

A Trump Account is a traditional-IRA-type account for an eligible child, with special rules during a growth period that generally ends on December 31 of the year the beneficiary turns 17. IRC §530A

How much can I put in a Trump Account each year?

Contributions are generally limited to $5,000 per year during the growth period, subject to statutory exceptions and future indexing rules. A separate government pilot contribution may be available for eligible children and is treated separately from the annual limit. IRC §530A

Can I invest a Trump Account in the S&P 500?

The account cannot generally buy individual S&P 500 stocks directly during the growth period. It may invest in an eligible mutual fund or ETF that tracks the S&P 500 and satisfies the statutory requirements for fees, leverage, and index composition. IRC §530A; 91 FR 54280

When can my child take money out of a Trump Account?

Distributions are generally prohibited before the year the beneficiary turns 18. After the growth period, ordinary traditional IRA distribution rules generally apply. IRC §530A

How is a Trump Account taxed when money is withdrawn?

The account is not a Roth IRA. After the growth period, distributions are generally analyzed under traditional IRA rules and may be taxable as ordinary income, with additional tax considerations for some early distributions. IRC §§ 530A, 408(d), 72(t)

Can a Trump Account be rolled into a Roth IRA?

The special Trump Account rules do not provide for a direct rollover to a Roth IRA. After the growth period, a traditional IRA transfer may be available, and a later Roth conversion from that traditional IRA may be considered separately. IRC §§ 530A, 408(d), 408A

Next Steps

Trump Account planning involves more than entering $5,000 into a compound-interest formula. Families should document contributions, confirm that investments remain eligible, understand the account’s post-growth-period treatment, and model future taxes before treating the balance as available spending money.

Disclaimer: This Is Math, Not Financial Advice

Brick Taxes is not a financial consulting firm, and we do not provide financial, investment, or portfolio advice. Nothing in this article is a recommendation to open a Trump Account, to buy, sell, or hold any security, or to adopt any particular investment strategy.

What this article does is show the mathematics of compounding and what a well-executed Trump Account contribution pattern can produce on paper. It is an illustration, not a projection, and the assumptions behind it are stated so you can judge them yourself.

We recommend that you run any of this information past your own financial advisor, and that you review the assumptions with someone who knows your complete picture — your income, your tax bracket, your other accounts, your risk tolerance, and your goals.

If you do not currently work with a financial advisor, we would encourage you to find one. There is no referral arrangement here and we receive nothing for saying so. It is an observation from years of client work: the difference between the clients who work with a financial advisor and those who do not is substantial, and it tends to show up over decades rather than months.

Brick Taxes handles the tax side of the picture — contributions, distributions, Roth conversion analysis, and how retirement income interacts with the tax code. Investment advice is a separate discipline, and a complete plan uses both.

A note from Matthew Jones, Enrolled Agent

There was a stretch of my career when I believed I could handle all of this myself — that the planning was obvious enough and that an advisor was an unnecessary cost. I was wrong, and looking back, I wish I had been less stubborn about it. That is a lesson most people learn the hard way, and the earlier you learn it, the more it is worth. Ideally, you learn as you live.
