Eligibility rules: who qualifies, and for what
The program has two eligibility layers that families constantly conflate. Account eligibility covers children under 18 — the account framework itself is not limited to the famous birth window. Seed eligibility is narrower: the federal $1,000 belongs to children born January 1, 2025 through December 31, 2028, per the full eligibility guide, while the Dell Foundation’s $250 reaches children age 10 and under born before 2025 in qualifying ZIP codes — the older-kids guide maps that class. Children born after the window get the account without the federal seed, as the post-2028 guide explains, and adults get neither — the age-rules page closes that question permanently.
The citizenship layer: the statute ties eligibility to U.S.-citizen children with Social Security numbers — the SSN requirements guide covers the documentation rules and the verification path for edge cases. And the establishment rule sits on top of all of it: a parent or guardian opens the account, one per child, under the one-account rules — with the divorce-priority rules deciding who holds the pen when households are split.
Money-in rules: contributions, caps, and channels
Three pipes carry money in, each with its own rulebook. Personal contributions — parents, grandparents, relatives, friends — all share the child’s single annual cap; there is no per-giver allowance, which is the trap the who-can-contribute guide defuses with light family coordination. Employer contributions ride their own channel with favorable tax treatment up to the excluded-benefit ceiling — the employer rules cover the mechanics, the employer-ask playbook covers getting the benefit created, and the self-employed guide covers business-owner parents. Qualified charitable gifts — the Dell model — process through Treasury cycles into accounts that exist, tracked on the match-programs page.
The calendar rules matter too: contribution years, deadlines, and the cost of late starts live in the timing guide, the gift-tax interaction for generous relatives lives in the gift-tax guide, and the deductibility question — the one every parent asks at tax time — gets its straight answer in the deduction guide. Strategy for how much to actually send: the contribution framework.
Investment rules: what the money must be in
The investment rule is short because the statute made it short: account funds go into eligible low-cost index funds tracking the broad U.S. market — S&P 500-style diversification with expenses capped near the industry floor. No individual stocks, no sector bets, no crypto, no active trading; the investment-options guide explains the design and defends it. The corollary rule families miss: there is no fixed interest rate — these are market accounts, not savings accounts, and the interest-rate page corrects that premise with the real return math.
What that produces over time is the program’s whole thesis: the seed-growth math shows the historical ranges, the calculator runs your child’s exact scenario, and the honest caveat stands everywhere on this site — projections are illustrations, market risk is real, and the mistakes guide ranks treating projections as promises among the errors that cost families most.
Money-out rules: the lock, the handoff, the taxes
The access rules are the program’s spine: contributions and seeds are committed through the growth period — no early raids, no emergency-fund double-duty — and at adulthood the child becomes the account holder, taking ownership under the withdrawal rules. Two facts inside those rules do the most planning work: the money is genuinely the child’s at the handoff (parents wanting strings should read the custodial comparison first), and nothing forces withdrawal at 18 — balances can stay invested through the early adult years, often the wise move.
The tax rules complete the picture: growth compounds tax-deferred during the lock, and withdrawals are taxed under the framework the taxes guide details — treatment that trails a correctly-used 529’s education exit and a Roth’s qualified exit, which is precisely why the worth-it analysis routes education-certain and earned-income dollars through the comparison series before landing here. Filing mechanics, when they arise, run through the paths in the Form 4547 guide.
The administrative rules — and the anti-rules
The housekeeping rules that keep families out of trouble: one account per child, enforced — duplicates create the cleanup sagas the one-account guide exists to prevent; official channels only for opening and managing — the opening walkthrough and the official app guide mark the real doors, and the balance-check guide covers monitoring; and records always — screenshot every deposit, per the discipline the troubleshooting guide is built on.
And the anti-rules — the things that are never true, no matter what arrives in your inbox: enrollment is never sold, eligibility is never “unlocked” for a fee, adults never qualify for themselves, and no legitimate party ever requests your child’s SSN by text or social ad. Every violation of those anti-rules is a specimen for the scam catalog. The rulebook’s deepest pattern, once you see it: every real rule is free to follow, and everything that costs money to “comply” with is fake.
