The Day My Daughter Asked Where Money "Lives"
My 9-year-old, Zoe, came home from school last spring with $23 in crumpled bills — birthday money from her grandma that had been sitting in her backpack for two weeks. She handed it to me and said, "Can you put this somewhere safe? Like, where does money actually live when it's not in your wallet?"
I laughed. And then I realized: I had never actually shown her. I talk to my kids about money constantly — we do the 3-jar system for kids, we talk about saving vs. spending — but I had never walked her through what a bank account actually is, or how to get one. I just assumed she'd figure it out eventually, the way I did. At 34. After making some truly embarrassing financial mistakes.
So we sat down together and I opened a custodial bank account for her that same week. It took about 20 minutes. And honestly? It was one of the best money conversations we've ever had.
If you've been putting this off — maybe because you're not sure what you need, or which bank to pick, or whether your kid is even old enough — this is the guide I wish I'd had. Let's make it simple.
What "Bank Account for a Minor" Actually Means
Here's the thing nobody tells you upfront: minors (anyone under 18) legally can't enter into contracts on their own. And opening a bank account is a contract. So banks require an adult — usually a parent or legal guardian — to be on the account too.
That co-ownership setup has a few different names depending on the bank and account type. Here's a quick breakdown:
Joint Account
Both you and your kid are equal account holders. Both of you can deposit, withdraw, and access funds. This is the most common setup for younger kids. It's simple, and most banks offer it. The downside: you have full visibility and control, which is great for a 10-year-old, but might feel like surveillance to a 16-year-old.
Custodial Account (UGMA/UTMA)
This is slightly different — it's designed more for investing than everyday banking. You (the custodian) control the account until your kid reaches the age of majority (18 or 21, depending on your state), at which point the assets transfer fully to them. If you're thinking about opening an investment account rather than a checking/savings account, check out Investopedia's breakdown of custodial accounts — it's genuinely helpful.
Student Checking or Teen Checking Accounts
Many banks now offer accounts specifically marketed to teens (usually ages 13–17). These often come with a debit card, spending alerts, and parental controls built in. Think: Chase First Banking, Capital One MONEY, Greenlight, or Copper. These are often the sweet spot for tweens and teens who want some independence but still need guardrails.
For most families just getting started, a joint savings or teen checking account is the right move. You can always layer in more complexity later. And if you're still figuring out the age piece, I wrote more about how old to open a bank account — worth a read before you pick a product.
What You'll Actually Need to Open the Account
This is where people get tripped up. You show up at the bank (or start the online application) and realize you're missing something. Here's the full list so that doesn't happen to you.
For the Parent or Guardian:
- Government-issued photo ID (driver's license or passport)
- Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN)
- Your home address and contact information
- An existing bank account or debit card to fund the initial deposit (some banks require a minimum — often $0–$25)
For Your Kid:
- Their Social Security Number — yes, even for a 7-year-old. This is non-negotiable for most banks.
- Birth certificate (especially for younger children who don't have a school ID)
- For teens: a school ID, state ID, or passport can work as secondary ID
If You're Not the Parent (Legal Guardian, Aunt, Uncle, etc.):
This comes up more than you'd think. You'll likely need documentation proving your guardianship — court papers, a notarized letter from the parent, or similar. Call the specific bank ahead of time and ask what they require. Don't assume — every institution handles this differently. (More on this in the "What Parents Are Actually Asking" section below.)
The Consumer Financial Protection Bureau (CFPB) has solid guidance on what rights minors have in banking — worth bookmarking if you want the regulatory background.
Step-by-Step: How to Open the Account
Okay, let's actually do this. Here's how it works, whether you're going in-person or online.
Step 1: Pick Your Bank or Credit Union
Don't just default to wherever you bank. Ask yourself: Does this bank have a teen/kid-specific account? What are the fees? Is there a minimum balance? Can my kid eventually get a debit card? Some options I like:
- Chase First Banking — No fees, parental controls, works with your Chase account
- Capital One MONEY — No fees, no minimums, great app
- Alliant Credit Union — Strong savings rates for kids
- Greenlight — Not a traditional bank, but excellent for teaching spending habits with a debit card

Step 2: Gather Your Documents (See Above)
Don't skip this. The number one reason people abandon the process halfway is missing their kid's SSN or birth certificate. Get it all in one folder before you start.
Step 3: Apply Online or In-Branch
Most major banks let you open a joint or custodial account online now. You'll fill out the application with your info and your kid's info. Some banks will ask you to verify identity by uploading photos of documents. In-branch is sometimes faster for non-standard situations (like if you're a non-parent guardian).
Step 4: Make the Initial Deposit
Even $5 works at most banks. Let your kid be the one to "put the money in" — even if it's just clicking a button on a screen. The ritual matters.
Step 5: Set Up Notifications and Parental Controls
Most teen accounts let you set spending limits, get alerts for every transaction, and block certain merchant categories. Take 10 minutes to configure this. You don't need to be surveillance-mode, but knowing when your 13-year-old spends $40 at the game store is useful information.
Step 6: Make It a Conversation, Not a Chore
Show your kid the account. Explain what a routing number is. Talk about what interest means (even 0.01% is a starting point for the concept). Next Gen Personal Finance has some genuinely great free resources if you want to turn this into a bigger learning moment.
Common Mistakes Parents Make (And How to Dodge Them)
I've made some of these myself. No shame — just skip them if you can.
- Opening the account and never talking about it again. The account is a tool, not a finish line. Check in monthly. Look at the balance together. Make it normal.
- Picking a bank with hidden fees. Monthly maintenance fees, low-balance fees, ATM fees — these will eat a kid's savings fast and feel incredibly discouraging. Read the fine print. Look for $0 fee accounts specifically designed for minors.
- Not getting your kid a debit card. I know it feels scary. But a debit card with a $20 limit teaches more in one weekend than six months of allowance in a jar. Start small. Let them make a mistake. That's the point.
- Putting the account in only your name "for simplicity." If the account is only in your name, your kid has no ownership — legally or emotionally. The whole point is that it's theirs.
- Waiting until they're a teenager. I didn't know this until my 30s: the earlier you start, the more ingrained the habits get. You can open an account for a 6-year-old. You can open one for a baby, technically. Earlier is almost always better.
- Skipping the "why" conversation. Don't just hand them a card. Explain: this is where your money lives. When you earn it or receive it, it goes here. When you want to spend it, it comes from here. That mental model is everything.
What Parents Are Actually Asking
I spend a lot of time reading what parents are genuinely confused about. Here's what's coming up again and again:
"How do you get a bank account as a minor? Most banks require a parent to co-sign but I want my teen to have some independence."
"Can I open a bank account for a minor that isn't my child? My niece is living with us and needs an account for her part-time job."
The short answer: yes, you can open an account for a minor who isn't your biological child, but you'll need to be a legal guardian or have the parent's written consent — and every bank handles this differently. Call ahead and ask specifically about their custodial or joint account policies for non-parent guardians.
FAQ: Bank Accounts for Minors
What is the minimum age to open a bank account for a minor?
There's no federal minimum age — it varies by bank. Many banks will open a joint savings account for a child of any age, including infants. Teen checking accounts (with debit cards) are typically available starting at age 13. Check your specific bank's policy, but don't assume you have to wait until your kid is a teenager.
Can a minor open a bank account without a parent?
In most U.S. states, no — not a traditional bank account. Because minors can't legally sign contracts, a parent or guardian must be a joint account holder. A few fintech apps (like Step) allow teens to open accounts with more independence, but a parent still has to be involved in the setup process.
Does my kid need a Social Security Number to open a bank account?
Yes, for virtually all U.S. bank accounts. The bank is required to collect SSNs for tax reporting purposes under federal law. If your child doesn't have an SSN yet, some credit unions may work with an ITIN, but it's uncommon. Get the SSN sorted first.
What happens to the account when my kid turns 18?
For joint accounts, your kid can typically request to have you removed from the account once they're 18 — or you can both stay on it. For custodial (UGMA/UTMA) accounts, control automatically transfers to the minor when they reach the age of majority (18 or 21, depending on the state). Either way, it's worth having a conversation with your teen before that transition happens.
Is a savings account or checking account better for a kid?
For younger kids (under 10), a savings account is usually the right start — it reinforces the saving habit and keeps things simple. For tweens and teens, a checking account with a debit card is more practical and teaches real-world spending skills. Many banks offer combo accounts that do both.
Are there fees I should watch out for?
Yes — monthly maintenance fees, minimum balance fees, and out-of-network ATM fees are the big ones. Look specifically for accounts labeled "student," "teen," or "youth" — these are usually fee-free. Always read the fee schedule before opening, not after.
