A 529 plan (USA) and an RESP (Canada) are both tax-advantaged investment accounts designed to grow money for a child's education, but the RESP's defining feature is generous government matching grants that the U.S. 529 does not offer.
Education costs keep climbing on both sides of the border, and starting early is the single biggest advantage a parent has. These dedicated accounts let your savings compound tax-sheltered, and in Canada the government literally adds money on top. Below we explain how each works, what grants are available, and a worked example showing the power of starting young.
What Is a 529 Plan? (United States)
A 529 plan is a state-sponsored, tax-advantaged investment account for education expenses. You contribute after-tax dollars, the money is invested (commonly in age-based portfolios), and it grows free of federal tax. As long as withdrawals pay for qualified education expenses, the earnings come out tax-free too.
- Tax-free growth and withdrawals for qualified expenses such as tuition, fees, books, and room and board.
- Possible state tax break: many states offer a deduction or credit for contributions.
- High limits: aggregate balances often exceed $300,000 per beneficiary, with no annual federal contribution cap (though large gifts interact with the gift-tax exclusion).
- Up to $10,000 per year can go toward K-12 tuition, and unused funds can be rolled into a Roth IRA within strict limits.

What Is an RESP? (Canada)
A Registered Education Savings Plan (RESP) is the Canadian equivalent, and its headline feature is free government money. Contributions are not tax-deductible, but investments grow tax-deferred, and the government tops up your savings with grants.
The Grants That Make RESPs Special
- Canada Education Savings Grant (CESG): the government matches 20% of your annual contributions, up to $500 per year and $7,200 lifetime per child.
- Canada Learning Bond (CLB): up to $2,000 for children from lower-income families, with no contribution required.
- Provincial grants in places like British Columbia and Quebec add even more.
On withdrawal, the grants and growth (called Educational Assistance Payments) are taxed in the student's hands, usually at a very low or zero rate. Your original contributions come back tax-free.
529 vs. RESP: Key Differences
- Government match: RESPs get the CESG; 529 plans get no federal matching grant.
- Tax break on contributions: some U.S. states give a deduction for 529 contributions; RESP contributions are never deductible.
- Withdrawal tax: qualified 529 withdrawals are fully tax-free; RESP growth and grants are taxed to the student.
- Time limit: 529 plans have no expiry; an RESP can stay open up to 35 years.
Worked Example: The Power of Starting Early
Suppose Canadian parents contribute $2,500 per year to an RESP from birth. The CESG adds 20%, or $500 per year, so $3,000 actually goes to work annually. Assuming a 6% average annual return compounded over 18 years:
- Total parent contributions: $2,500 × 18 = $45,000
- Total CESG grants: $500 × 14.4 years (to the $7,200 cap) = $7,200
- Estimated balance at age 18 with 6% growth: roughly $95,000
That nearly $43,000 of growth-plus-grants on top of the contributions is the compounding engine at work, and the $7,200 grant alone is free money no U.S. 529 can match.

Which Account Is Right for You?
Your country generally decides the account: U.S. families use 529 plans, Canadian families use RESPs. The universal advice is the same in both countries: start early, automate contributions, and, if you are in Canada, contribute at least enough to capture the full annual CESG, because a guaranteed 20% return is unbeatable. Pair an education account with broader retirement and brokerage investing so one goal does not crowd out another.

Frequently Asked Questions
What is a 529 plan?
A 529 plan is a tax-advantaged U.S. investment account for education. Your contributions grow tax-free, and withdrawals are tax-free when used for qualified education expenses such as tuition, fees, books, and room and board. Many states also offer a state income tax deduction or credit for contributions.
What is an RESP and what grants does it get?
An RESP is a Registered Education Savings Plan in Canada. Its biggest advantage is the Canada Education Savings Grant, which matches 20 percent of your annual contributions up to 500 dollars per year and 7,200 dollars lifetime per child. Lower-income families may also receive the Canada Learning Bond and additional CESG.
What is the difference between a 529 plan and an RESP?
A 529 plan is American and offers tax-free growth plus possible state tax breaks but no federal matching grant. An RESP is Canadian and its standout feature is government matching through the CESG. In an RESP, contributions are not tax-deductible, but growth is tax-deferred and grants plus earnings are taxed in the student's hands on withdrawal.
What happens if my child does not go to college?
With a 529 plan you can change the beneficiary, withdraw funds (earnings face tax plus a 10 percent penalty), or roll a limited amount into a Roth IRA. With an RESP, you may keep the plan open for up to 35 years, transfer it to a sibling, or withdraw your own contributions tax-free, though unused grant money must be returned to the government.
