What you need to open a high yield savings account
Opening a high yield savings account takes 10 to 20 minutes and requires three things: a government-issued ID, proof of your current address, and your Social Security number. Most banks let you start online without visiting a branch. You'll need to fund the account with an initial deposit—amounts vary by bank, from $0 to $25,000—though some banks waive the minimum if you set up automatic transfers.
The process is the same whether you bank online-only or at a traditional bank with branches. You create a login, verify your identity (usually by uploading a photo of your ID), confirm your address, and link a funding source. The bank then transfers money from your existing checking or savings account to seed the new account. Approval is usually instant, though some banks take up to one business day to verify your information.
You do not need to close your current savings account or switch banks entirely. A high yield savings account can sit alongside whatever you already have—at the same bank or a different one. Many people keep their checking account where it is and open a high yield account elsewhere specifically for the better rate.
Key Takeaways
- You need a government ID, proof of address, and Social Security number; most banks let you complete the entire process online in under 20 minutes.
- Initial deposit requirements range from $0 to $25,000 depending on the bank, and you fund the account by linking an existing bank account.
- Opening a high yield account does not require closing your current savings account or switching banks.
- Money transferred into a high yield account typically arrives within one to three business days, and you can withdraw it the same way.
- The account earns interest on your balance automatically; the rate is set by the bank and can change, so check the current APY before you open.
Documents and information to gather before you start
Have your government-issued ID ready—a driver's license, passport, or state ID card. The bank will ask you to photograph both sides or upload a digital copy. If you do not have a physical ID, some online banks accept a passport card or tribal ID; call the bank first to confirm what they take.
You'll also need proof that you live where you say you do. A recent utility bill, lease, mortgage statement, or government document with your name and address works. The document usually needs to be dated within the last 60 to 90 days. If you've moved recently and your ID doesn't match your current address, bring both your old and new proof.
Have your Social Security number written down or memorized. The bank uses it to run a background check and report interest earnings to the IRS. If you do not have a Social Security number but are a U.S. resident, some banks accept an Individual Taxpayer Identification Number (ITIN) instead; ask before you apply.
Finally, know the routing and account number of the bank account you'll use to fund the new account. This is usually printed on a check or visible in your online banking portal. If you're funding from a credit union or smaller bank, you may need to call them to get the routing number.
Step-by-step process for opening online
Go to the bank's website and click the button to open a new savings account. You'll be asked to choose the account type—select "high yield savings" or "money market account" (the terms vary by bank, but both refer to accounts with higher interest rates). Enter your basic information: name, date of birth, email, and phone number.
The bank will then ask for your Social Security number and current address. Enter these exactly as they appear on your ID and official documents. Next, you'll upload or photograph your ID. Most banks let you use your phone camera; take clear photos of both the front and back, making sure all text is readable and the corners are visible.
Upload your proof of address the same way. Then link the bank account you'll use to fund the new account by entering its routing number and account number. The bank will verify this by making two small test deposits (usually $0.01 to $0.99 each) to that account. You'll need to log into your old bank and confirm the amounts to prove you own the account.
Choose your initial deposit amount and confirm it will be pulled from your linked account. Review the account terms, including the current APY, any fees, and the minimum balance required to earn the stated rate. Sign the electronic agreement and submit. Most banks approve you instantly; others send a confirmation email within a few hours.
How long it takes to access your money
Your account is usually open and ready to use the same day you apply, though some banks take up to one business day. However, the money you transfer in does not arrive instantly. A transfer from another bank typically takes one to three business days because it moves through the ACH (Automated Clearing House) network, which processes in batches.
If you're funding from an account at the same bank—for example, transferring from your checking account to a new savings account at the same institution—the money usually appears within hours or by the next business day. Transfers out of your high yield account follow the same timeline: one to three business days to reach another bank, same-day or next-day if you're moving money within the same bank.
Some banks offer faster funding through wire transfer, but this usually costs $15 to $30 and is rarely worth it for opening an account. If you need the money urgently, fund the account from a checking account at the same bank instead.
Fees and minimum balance requirements
Most high yield savings accounts charge no monthly maintenance fee, no overdraft fee (because you cannot overdraft a savings account), and no fee to open or close the account. However, some banks impose a fee if your balance drops below a certain threshold—commonly $2,500 to $25,000—or if you make more than a set number of withdrawals in a month.
Check the fee schedule before you open. Look for: monthly service charge, minimum balance requirement, excess withdrawal fee, and wire transfer fee. If the bank charges a fee to maintain the account, calculate whether the interest you'll earn outweighs it. For example, if a bank pays 4.5% APY but charges $10 per month if your balance is under $10,000, you'd need at least $26,667 in the account to break even on the fee.
The federal limit on savings account withdrawals was removed in 2020, so most banks no longer restrict how many times you can withdraw per month. However, some still charge a fee after a certain number of withdrawals—usually six per month. If you plan to move money in and out frequently, choose a bank with no withdrawal limits or no excess withdrawal fees.
Moving money in and out of your account
Once your account is open and funded, you can add money by transferring from another bank account (one to three business days), by direct deposit from your employer (same timeline as your paycheck), or by wire transfer (same day, but usually costs $15 to $30). You can also deposit cash at some banks if they have physical branches, though online-only banks do not accept cash deposits.
Withdrawing money works the same way: you can transfer to another bank account (one to three business days), request a check (three to seven business days to arrive), or withdraw cash at a branch if the bank has one. Some banks also let you link your high yield account to a debit card, though this is less common because the account is meant for saving, not spending.
Interest is deposited into your account automatically, usually monthly or daily depending on the bank. The amount depends on your balance and the current APY. If the bank changes the rate, they'll notify you by email or through your online portal; the new rate takes effect on the date they specify, usually within 30 days.
Comparing rates and choosing which bank to use
High yield savings rates change frequently—sometimes weekly—so the rate you see today may not be the rate you get tomorrow. Before you open, check the current APY on the bank's website and confirm it applies to the balance you plan to deposit. Some banks offer a higher rate only on balances above a certain amount, or for a limited time.
Compare at least three banks. Online-only banks (like Marcus, Ally, or Wealthfront) typically offer higher rates than traditional banks because they have lower overhead costs. However, traditional banks sometimes match or beat online rates to keep customers. Look at the APY, any fees, the minimum deposit, and whether the bank offers other products you might use (like checking accounts or CDs).
Also consider whether you want your high yield account at the same bank where you keep your checking account. Keeping everything in one place makes transfers faster and simpler, but spreading accounts across banks can be a safety measure—the FDIC insures up to $250,000 per account type at each bank, so splitting your savings across two banks doubles your coverage.
What happens after you open
Once your account is open, you'll receive a confirmation email with your account number and login credentials. Log into your online portal to see your balance, transaction history, and current APY. Set up alerts if the bank offers them—many let you receive notifications when your balance drops below a certain amount or when interest is deposited.
Check your account regularly, especially in the first month, to make sure deposits arrived and interest is being calculated correctly. If you notice an error, contact the bank's customer service immediately. Most banks have a dispute window of 60 days from when the error occurred.
Your interest rate will change over time as the bank adjusts it in response to market conditions. You do not need to do anything when the rate changes—it happens automatically. However, if the rate drops significantly and another bank is offering more, you can open a second high yield account elsewhere and move your money. There is no penalty for closing a high yield savings account.
Frequently Asked Questions
Can I open a high yield savings account if I have bad credit?
Yes. Banks do not check your credit score when you open a savings account. They run a background check using your Social Security number to verify your identity and check for fraud, but this does not affect your credit. You can open a high yield account even if you have unpaid debts or a low credit score.
What if I do not have a Social Security number?
Some banks accept an Individual Taxpayer Identification Number (ITIN) instead. Call the bank before you apply to confirm they take ITINs and what additional documents you'll need to provide. You may also need to visit a branch in person rather than opening online.
Can I open a high yield account for someone else, like a child?
No, you cannot open an account in someone else's name. However, you can open a custodial savings account for a minor, which you control until they reach the age of majority (usually 18 or 21). The bank will ask for the child's Social Security number and your relationship to them. Interest earned in a custodial account is taxed to the child, which may result in lower taxes overall.
What if the bank rejects my application?
Banks rarely reject applications for savings accounts, but it can happen if there's a discrepancy in your identity information, a fraud alert on your Social Security number, or a history of unpaid bank fees. If you're rejected, ask the bank why. You can dispute errors with the bank or with the credit bureau if the issue is a fraud alert. Try applying at a different bank while you resolve the problem.
Do I have to keep a minimum balance to earn the advertised APY?
It depends on the bank. Some banks pay the full APY on any balance, no matter how small. Others require a minimum balance—often $2,500 to $25,000—to earn the stated rate. Balances below the minimum may earn a much lower rate or no interest at all. Check the bank's terms before you open to confirm what minimum applies to the rate you're seeing.
