What you need to open a college savings account

You can open a college savings account with just a Social Security number for the child, your own identification, and an initial deposit — usually between $0 and $25 depending on the account type and institution. Most banks and investment firms let you open online in 10 to 15 minutes. You do not need the child to be present, and you do not need to wait until they are a certain age.

The specific documents vary slightly by bank and account type. For a 529 plan (the most common college savings vehicle), you will need the child's full name, date of birth, and Social Security number. For a regular custodial savings account at a bank, you typically need the same information plus your own ID. If you are opening through an investment firm like Vanguard or Fidelity, they may ask for your employment information and income range, but this is for account classification, not approval.

Some states offer 529 plans directly through their state treasurer's office or a designated plan manager. Others let you choose from multiple plans, including out-of-state options. Starting with your own state's plan is often simpler because some states offer tax deductions on contributions — but only if you use their plan.

Key Takeaways

  • A 529 plan is a tax-advantaged savings account designed specifically for college costs and requires only the child's Social Security number and your ID to open.
  • You can open a 529 plan online in minutes through your state's plan, a private investment firm, or a brokerage, with initial deposits as low as $0 to $25.
  • Some states offer income tax deductions on 529 contributions, but only if you use that state's plan — check your state's rules before choosing.
  • A custodial savings account at a regular bank is simpler but offers no tax advantages and may limit how much you can save without triggering tax reporting requirements.

529 plans versus custodial savings accounts

A 529 plan is a state-sponsored investment account where money grows tax-free as long as it is used for college expenses. You choose how to invest the money — usually from a menu of age-based portfolios or individual funds — and earnings are never taxed at the federal level. If your state offers a tax deduction for contributions, you also avoid state income tax on the money you put in. When the child attends college, withdrawals for tuition, room and board, books, and fees come out tax-free.

A custodial savings account (also called a UTMA or UGMA account) is a regular bank savings or investment account held in the child's name but controlled by you until they reach age 18 or 21, depending on your state. Money in the account belongs to the child legally, and any earnings are taxed at the child's tax rate — which is usually lower than yours, but still taxed. Custodial accounts are simpler to open and manage, but they offer no special tax breaks and count heavily against financial aid may be able to access because the money is considered the child's asset.

For most families, a 529 plan is the better choice because of the tax advantages and because it does not reduce financial aid may be able to access as much as a custodial account does. However, if you want maximum simplicity and do not expect to save more than a few thousand dollars, a custodial account at your bank works fine.

How to choose a 529 plan

Start by checking whether your state offers a tax deduction for 529 contributions. If it does, using your state's plan usually makes sense because you get an immediate tax break. Search "[your state] 529 plan" or visit your state treasurer's website to find the official plan and see the deduction amount — it ranges from $235 per year in some states to $500 or more in others.

If your state does not offer a deduction, or if the deduction is small, you can choose any state's 529 plan. Compare plans by looking at investment options (age-based portfolios are easiest for beginners), annual fees (typically 0.3% to 1% of your balance), and minimum initial deposits. Vanguard, Fidelity, and Schwab offer low-cost 529 plans with no minimum or very low minimums. Some plans charge $50 to $100 per year in account fees, while others charge nothing.

You do not have to pick the "best" plan — any 529 plan will work. The difference between a low-cost plan and a high-cost plan on a $10,000 balance over 10 years is roughly $1,000 to $2,000 in fees, so it matters, but it is not a make-or-break decision. Pick one, open it, and start saving.

Steps to open a 529 plan online

Go to the website of the 529 plan you chose — either your state's official plan or a private provider like Vanguard. Click the button to open a new account. You will be asked for the account owner's information (you), the beneficiary's information (the child), and your relationship to the child.

Enter the child's full name, date of birth, and Social Security number exactly as they appear on their Social Security card. Enter your own name, address, date of birth, and Social Security number. You will also provide your bank account information so you can link it for deposits. Most plans let you fund the account immediately with a bank transfer or set up automatic monthly contributions.

Choose your investment option. If you are new to investing, select an age-based portfolio — the plan automatically shifts the money from stocks to bonds as the child gets closer to college age. If you prefer to choose individual funds, most plans offer a range of stock and bond index funds. You can change your investment choice once per calendar year, or whenever the beneficiary changes schools.

Review the account agreement, sign electronically, and submit. The account is usually active within one to three business days. You will receive a confirmation email with your account number and login credentials.

How much to contribute and when

There is no required minimum contribution amount — you can open an account with $0 and add money whenever you can. However, the more you save early, the more time your money has to grow. A $100 monthly contribution starting at birth grows to roughly $30,000 to $35,000 by age 18, depending on investment returns. The same $100 monthly contribution starting at age 10 grows to roughly $15,000 to $18,000.

Contributions are limited by federal law: you can give up to $18,000 per person per year (as of 2024) without filing a gift tax return. Married couples can give $36,000 per year per child. These limits reset each January, so you can contribute the full amount every year without tax consequences. Over a child's lifetime, you can contribute up to $235,000 per beneficiary in a 529 plan (the exact limit varies by state, but most are in this range).

If you receive a tax refund, a bonus at work, or a gift from a relative, putting it into the 529 plan is a straightforward way to boost savings without changing your monthly budget. Many plans let you set up automatic transfers from your checking account on a schedule you choose — weekly, monthly, or quarterly.

What happens to the money if the child does not attend college

If the child does not attend a four-year college, you have options. They can attend a community college, trade school, or vocational program and use the money for tuition and fees there — 529 plans cover those costs too. They can also use the money to pay down student loans after they graduate, up to $35,000 lifetime per beneficiary.

If the money goes unused, you can change the beneficiary to another family member — a sibling, cousin, niece, or nephew — without penalty. The money stays in the account and keeps growing tax-free under the new beneficiary's name. If you withdraw the money for non-college expenses, you pay income tax on the earnings portion plus a 10% penalty, but the contributions you made come out tax-free.

Some states now allow you to roll unused 529 money into a Roth IRA for the beneficiary, up to certain limits. This is a newer option, so check whether your plan offers it.

Frequently Asked Questions

Can I open a 529 plan if I do not have a Social Security number?

Most 529 plans require a Social Security number for the child to open an account. If the child does not have one yet, you can request one from the Social Security Administration — it takes about two weeks. Some plans let you open an account with an Individual Taxpayer Identification Number (ITIN) instead, so call your plan provider to ask.

What if I want to save for college but do not want to use a 529 plan?

A custodial savings account at any bank works, though it offers no tax advantages. You can also save in your own name in a regular savings account, though this counts against financial aid more heavily than a 529 does. Some families use a combination — a 529 for the bulk of savings and a regular account for flexibility.

Can I change my mind about which 529 plan to use?

Yes. You can roll money from one 529 plan to another once per 12-month period without penalty. This is called a rollover. If you open a plan and later find a better one with lower fees or better investment options, you can move the money over. The process takes a few weeks and is handled by the plans themselves.

Do I have to use the money for the college the child attends?

No. The money can be used at any college, university, trade school, or vocational program in the United States or abroad, as long as it is accredited by the U.S. Department of Education. You can also use it for room and board off-campus, books, computers, and required equipment.

Will a 529 plan hurt my child's chances of getting financial aid?

A 529 plan in the parent's name counts as a parental asset and reduces financial aid may be able to access by roughly 5% of the balance. A 529 in the child's name counts as a student asset and reduces aid by roughly 20% of the balance. For this reason, it is better to open the account in your name as the account owner, even though the child is the beneficiary.
