What you need to open a Fidelity high-yield savings account

Fidelity offers a high-yield savings account called the Fidelity Government Money Market Fund (SPAXX) paired with a Fidelity Cash Management Account. To open one, you need a Social Security number, a valid government ID, proof of address (a recent utility bill or bank statement), and $0 to start—Fidelity has no minimum deposit requirement for this account type.

The account opens online in about 10 minutes. You'll provide your name, address, employment status, and citizenship information. Fidelity will verify your identity using information from credit bureaus and public records. Once approved, you can fund the account by linking a bank account and transferring money, or by depositing a check through their mobile app.

The account itself is free to maintain. There are no monthly fees, no inactivity fees, and no fees for transfers or withdrawals. The interest rate changes daily based on market conditions, so the APY you see when you open the account will not be locked in—it moves with the broader money market rate.

Key Takeaways

  • Fidelity's high-yield savings option is a Cash Management Account holding the Government Money Market Fund, which requires only a Social Security number, ID, and proof of address to open.
  • The account has no minimum deposit, no monthly fees, and no withdrawal limits, though the interest rate fluctuates daily with market conditions.
  • You can fund the account online by linking a bank account for transfers or by depositing a check through the Fidelity mobile app.
  • Money deposited into the account is FDIC insured up to $250,000 through Fidelity's partner banks, protecting your balance if Fidelity fails.

The online process process, step by step

Start at fidelity.com and click "Open an Account." Select "Cash Management Account" from the account type menu. You'll be taken through a series of screens asking for your name, date of birth, Social Security number, address, phone number, and email. Have your ID ready—you may need to photograph it or answer security questions based on your credit history.

Next, you'll confirm your employment status and annual income (this is for regulatory purposes, not a requirement to earn money). You'll also choose how you want to fund the account: by linking an external bank account for transfers, or by mailing a check. If you link a bank account, Fidelity will send two small deposits to verify ownership—you'll need to confirm the amounts in your bank's app or online portal within a few days.

Once your identity is verified and your funding method is confirmed, the account is active. You can begin transferring money when ready if you linked a bank account. Transfers from another bank usually arrive within one to three business days. If you're depositing a check, photograph it in the Fidelity app and it will be processed within one to two business days.

How the interest rate works and when you'll see it

Fidelity's Government Money Market Fund pays interest daily, but you see it posted to your account monthly. The rate is not fixed—it changes based on what the Federal Reserve does with short-term interest rates. When the Fed raises rates, the APY on money market funds typically rises within days. When the Fed cuts rates, the APY falls.

The rate you see advertised on Fidelity's website is the current rate, updated daily. If you open the account today at 4.80% APY, that does not mean you'll earn 4.80% for a year. It means you're earning 4.80% right now, and the rate will change as market conditions shift. Over a full year, your actual return depends on how rates move during that time.

Interest compounds daily and posts monthly. If you have $10,000 in the account earning 4.80% APY, you'll earn about $40 that month (before the rate changes). The interest is automatically reinvested, so your balance grows and you earn interest on the interest the following month.

Moving money in and out of the account

You can transfer money into the account from any bank account you own. Link the external account through Fidelity's website or app, then initiate a transfer. Fidelity will ask whether you want the money to arrive as soon as possible (usually one to three business days) or on a specific date. There's no limit on how many transfers you can make or how much you can move.

Withdrawals work the same way. You can transfer money back to your linked bank account anytime, and it will arrive within one to three business days. You can also write checks directly from the Cash Management Account if you set up check-writing privileges, though this is less common for savings accounts. There are no withdrawal limits or fees.

If you need the money faster, you cannot get it the same day. Fidelity does not offer same-day transfers or when ready withdrawals. Plan ahead if you know you'll need the money on a specific date.

FDIC insurance and what happens if Fidelity fails

Money in a Fidelity Cash Management Account is FDIC insured up to $250,000 per account holder per bank. Fidelity partners with multiple banks—including Fidelity Bank, U.S. Bank, and others—to hold customer deposits. Your balance is spread across these partner banks automatically, so even if you have more than $250,000 in the account, the full amount is protected.

FDIC insurance covers the account if the bank holding your money fails. It does not cover losses from fraud, market downturns, or Fidelity's business failure. Your money is held at the partner banks, not at Fidelity itself, so if Fidelity closes, your deposits remain protected at the banks where they're held.

You can see which banks hold your money by logging into your Fidelity account and checking the Cash Management Account details. Fidelity publishes this information so you know exactly where your deposits are.

Comparing Fidelity's rate to other banks

Fidelity's Government Money Market Fund rate moves with the market, so it's competitive when rates are high and less competitive when rates fall. Right now, other banks offer similar rates—some slightly higher, some slightly lower, depending on the day and the bank. The difference between 4.75% and 4.85% is small on a $10,000 balance (about $8 per year), but larger on bigger balances.

What sets Fidelity apart is not the rate but the features: no minimum deposit, no fees, unlimited transfers, and the ability to link the account to other Fidelity investments if you use them. If you already have a Fidelity brokerage account, the Cash Management Account integrates seamlessly. If you don't, you might find a simpler experience at a bank that focuses only on savings.

Shop around before opening. Check the current rates at Fidelity, Marcus by Goldman Sachs, Ally Bank, and your own bank's high-yield savings option. The rate today is not the rate you'll earn next month, so focus on the bank's features and how straightforward it is to move money in and out.

Frequently Asked Questions

Can I open a Fidelity high-yield savings account if I don't have a Fidelity brokerage account?

Yes. The Cash Management Account is separate from a brokerage account. You can open it without owning any stocks, bonds, or mutual funds. If you later decide to invest, you can link the accounts so money flows between them easily.

What happens to my interest if the Federal Reserve cuts rates?

Your APY will fall. Money market funds track short-term interest rates closely, so when the Fed cuts, the rate on your account typically drops within days. There's no penalty for this—it's how the product works. If you want a locked-in rate, you'd need a certificate of deposit (CD) instead, which offers a fixed rate for a set term.

How long does it take to withdraw money from a Fidelity high-yield savings account?

Transfers to a linked bank account take one to three business days. Weekends and holidays don't count as business days, so a transfer initiated on Friday won't arrive until Tuesday or Wednesday. There's no way to speed this up to same-day or next-day delivery.

Is the interest I earn taxable?

Yes. Interest earned on a high-yield savings account is ordinary income and must be reported on your tax return. Fidelity will send you a 1099-INT form in January showing how much interest you earned the previous year. You'll owe federal income tax on that amount, and possibly state income tax depending on where you live.

Can I have multiple Fidelity high-yield savings accounts?

Yes, but FDIC insurance covers only $250,000 per account holder per bank, not per account. If you open two Cash Management Accounts at Fidelity, the total balance across both is insured up to $250,000 combined. Opening multiple accounts doesn't increase your insurance coverage.
