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 do this entirely online—you upload photos of your ID and a recent utility bill or bank statement, answer identity verification questions, and fund the account from an existing bank account or by transfer.
Some banks still require you to visit a branch in person, but this is rare. Online banks like Marcus, Ally, and American Express Personal Savings have no physical branches at all. Credit unions and regional banks may require an in-person visit or a video call with a representative, so check their website before you start.
You do not need a minimum deposit to open most high-yield savings accounts. A few banks ask for $25 or $100 to fund the account on day one, but many have zero minimum. The account itself costs nothing to maintain—there are no monthly fees, no inactivity fees, and no penalty for keeping a small balance.
Key Takeaways
- You can open a high-yield savings account online in 10 to 20 minutes with an ID, proof of address, and your Social Security number.
- Most online banks have no minimum deposit requirement and charge no monthly maintenance fees.
- The APY (annual percentage yield) varies by bank and changes weekly, so compare rates across at least three banks before you choose.
- Your deposits are insured up to $250,000 per account by the FDIC (or NCUA if the bank is a credit union), so your money is protected even if the bank fails.
- You can transfer money into the account from another bank within one to three business days, or deposit cash at a branch if the bank has physical locations.
Where to find high-yield savings accounts and compare rates
High-yield savings accounts are offered by online banks, credit unions, and some traditional banks. Online banks almost always have the highest rates because they have lower overhead costs than banks with branches. Traditional banks often offer lower rates but may give you the option to deposit cash in person or speak to someone at a branch.
To compare rates, visit the banks' websites directly—do not rely on rate-comparison sites, which may be outdated or incomplete. Write down the APY for each bank, the minimum deposit (if any), and whether the rate is may provide or subject to change. The APY changes weekly based on Federal Reserve decisions, so a rate you see today may be different next week.
Check whether the bank is FDIC-insured (for banks) or NCUA-insured (for credit unions). This protects your deposits up to $250,000 if the bank fails. The FDIC and NCUA websites both have search tools where you can verify a bank's insurance status.
Step-by-step: opening an account online
Start by going to the bank's website and clicking the button to open a savings account. You will be asked for your name, date of birth, address, phone number, and email. Have your Social Security number ready—the bank will use it to run a credit check and verify your identity.
Next, you will upload photos of your ID (driver's license, passport, or state ID card) and proof of your current address. A utility bill, lease, or recent bank statement all work. Make sure the photos are clear and show the entire document. If the upload fails, the bank will tell you why and ask you to try again.
The bank will then ask identity verification questions based on your credit history—things like "Which of these addresses did you live at in 2019?" or "Which lender issued your car loan?" Answer honestly. If you get too many wrong, the bank may ask you to verify your identity by video call or in person.
Once you pass verification, you will choose a username and password, set up two-factor authentication (usually a code sent to your phone), and link a bank account to fund your new savings account. The bank will make two small test deposits (usually under $1 each) to your linked account within one to two business days. You then log in and confirm the amounts to prove you own that account. After that, you can transfer money into your high-yield savings account.
Funding your account and moving money in
You can fund a high-yield savings account in three ways: by transferring money from another bank account, by depositing a check through the bank's mobile app, or by depositing cash at a branch (if the bank has branches).
Bank-to-bank transfers usually take one to three business days. The bank will give you its routing number and your new account number so you can initiate the transfer from your other bank, or you can give the bank your other account details and let it pull the money. Both methods are safe and free.
Mobile check deposit works if you have a checking account at another bank. You photograph the front and back of the check using the savings bank's app, and the bank deposits it electronically. The funds usually arrive within one to two business days.
If you want to deposit cash, only some banks accept it. Marcus, Ally, and American Express have no branches, so you cannot deposit cash with them. Banks like Discover and Synchrony also have no branches. If cash deposits matter to you, choose a credit union or a regional bank with physical locations.
What happens after you open the account
Once your account is open and funded, you can log in anytime to check your balance and see your APY. The interest is calculated daily based on your balance and deposited monthly. If your balance is $10,000 and the APY is 4.50%, you earn about $37.50 per month (though the exact amount depends on the number of days in the month).
You can add money to the account anytime by transferring from another bank or depositing a check. Most banks limit the number of withdrawals or transfers out of a savings account to six per month (this is a federal rule, though it is enforced less strictly now). If you need to withdraw money more often, ask the bank about their withdrawal limits before you open the account.
The APY will change over time as the Federal Reserve raises or lowers interest rates. When rates drop, your bank's APY will drop too, usually within a week. When rates rise, your bank may take longer to raise its APY, so it pays to check rates every few months and switch banks if a competitor offers significantly more.
Choosing between online banks, credit unions, and traditional banks
Online banks offer the highest rates because they have no branches and lower costs. They are best if you do not need to deposit cash and are comfortable managing your account entirely through an app or website. Examples include Marcus, Ally, American Express Personal Savings, and Discover Bank.
Credit unions often offer competitive rates and may let you deposit cash at any ATM in their network. You must be a member to open an account, which usually means living or working in a certain area or belonging to a specific employer or organization. Credit unions are NCUA-insured, just like banks are FDIC-insured.
Traditional banks with branches offer lower rates but give you the option to deposit cash in person and speak to a representative if you have questions. They are best if you value in-person service or need to deposit cash regularly. Some large banks like Chase and Bank of America offer high-yield savings accounts, though their rates are usually lower than online banks.
Protecting your account and avoiding fraud
Once your account is open, use a strong, unique password—one you do not use anywhere else. Enable two-factor authentication, which requires a code from your phone or email every time you log in from a new device. This makes it much harder for someone to access your account even if they steal your password.
Do not share your account number, routing number, or login details with anyone. Banks will never ask for your password by email or phone. If someone contacts you claiming to be from the bank and asks for sensitive information, hang up and call the bank's official number from their website.
Check your account regularly—at least once a week. If you see a transfer you did not make, contact the bank immediately. The bank is required to investigate unauthorized transfers and return your money within a set timeframe (usually 10 business days for initial investigation, though the process can take longer).
Frequently Asked Questions
Can I open a high-yield savings account if I have bad credit?
Yes. Banks do not deny savings accounts based on credit score. They may run a credit check to verify your identity, but a low score will not stop you from opening an account. Some banks use ChexSystems (a banking history report) instead of credit, but again, a negative history rarely blocks you from opening a savings account.
What is the difference between a high-yield savings account and a regular savings account?
A regular savings account at a traditional bank pays very little interest—often 0.01% APY or less. A high-yield savings account pays much more, typically 4% to 5% APY depending on the bank and current interest rates. Over time, the difference adds up significantly. On $10,000, a regular account might earn $1 per year while a high-yield account earns $400 to $500.
Can I have multiple high-yield savings accounts?
Yes. You can open accounts at different banks to spread your money across multiple FDIC or NCUA insurance policies (each account is insured up to $250,000). Some people open accounts at two or three banks to diversify or to take advantage of different rates. There is no limit to how many accounts you can have.
What if I need to withdraw money quickly?
Transfers from a high-yield savings account to another bank account take one to three business days. If you need cash immediately, you cannot get it from a high-yield savings account unless the bank has branches where you can withdraw in person. For true emergency access, keep a small amount in a checking account and use the high-yield savings account for money you do not need right away.
Do I have to pay taxes on the interest I earn?
Yes. Interest earned in a high-yield savings account is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned, and you report that amount on your tax return. If you earn more than $10 in interest, the bank is required to send you the form.
