How Are HYSA and CD Interest Taxed?

Interest from a high-yield savings account (HYSA) or a certificate of deposit (CD) is taxed as regular income. The rate is the same as on your paycheck. You owe the tax in the year the bank adds the interest to your account, even if you never take it out. The bank doesn't hold any tax back, so it's up to you to plan for it.

1. What counts as interest income

Interest is the money a bank pays you for keeping your cash there. Your principal is the money you put in. The interest is the extra on top.

There are two common places to earn it:

A high-yield savings account (HYSA) is a savings account, often at an online bank, that pays a higher rate than a typical one. You can take money out any time.
A certificate of deposit (CD) pays a fixed rate for a set term, like 6 months or 3 years. If you cash it in early, the bank charges a penalty.

Banks quote rates as APY, or annual percentage yield. It's the interest you'd earn in a year, counting interest on your interest, if the rate stays the same. An HYSA rate can change at any time. A CD rate is locked for the term.

Interest is ordinary income. That means it's taxed at your regular bracket rate, the same as wages. It doesn't get the lower rates that long-term stock gains get.

2. Leaving it in the account doesn't delay the tax

This is the part that surprises people. You owe tax on interest in the year it's added to your account, whether you spend it or not.

Example: Jamie has $10,000 in an HYSA paying 4% APY. Over the year, the bank adds $400. Jamie doesn't touch it, but it's still $400 of income on her tax return.

Jamie is single, and her top tax bracket is 22%. All $400 lands in that bracket, so she owes $88 in federal income tax on it. She keeps $312 after federal tax.

The bank won't take that $88 out for her. She pays it when she files, or through withholding at work. Our tax brackets guide explains how your top rate works.

When interest crosses a bracket line

If extra interest pushes you into the next bracket, only the part above the line pays the higher rate.

Example: Omar is single and has $50,000 of taxable income in 2026. He earns $2,000 of CD interest. The 12% bracket ends at $50,400. So the first $400 is taxed at 12% ($48), and the other $1,600 at 22% ($352). His extra tax is $400, not 22% of the whole $2,000 ($440).

3. How CD interest is taxed

CDs follow the same basic rule, with one twist about when the interest counts.

CDs of one year or less that pay all the interest at the end are taxed in the year they pay out. A 6-month CD you open in October 2026 and cash in April 2027 counts as 2027 income.
CDs longer than one year are taxed on each year's interest as it builds up. This is true even if the interest isn't paid until the end and you can't touch it yet. The IRS calls this built-up interest original issue discount (OID). The bank may report it on Form 1099-OID instead of a 1099-INT.
CDs that add interest to your account monthly or yearly are taxed each year as the interest is added.

So "I can't withdraw it yet" doesn't mean "I don't owe tax yet." Your bank's year-end form shows how much counts for each year.

The early-withdrawal penalty is deductible

If you cash in a CD early, you still report the full interest you earned. Then you deduct the penalty separately. It's an above-the-line deduction, which means you get it even if you don't itemize. It goes on Schedule 1 of Form 1040, and the amount is shown on your 1099-INT.

Example: Priya earned $600 of CD interest but paid a $150 penalty for cashing in early. She reports $600 of interest and deducts $150. She's taxed on $450 in total.

4. Form 1099-INT and where interest goes on your return

Banks send Form 1099-INT when they pay you $10 or more of interest in a year. It usually arrives by the end of January.

You owe tax on interest even if no form comes. If one account paid you $8 and another paid $1,200, you report all $1,208.

Here's where it goes:

Taxable interest goes on line 2b of Form 1040.
If your taxable interest is over $1,500, you also fill out Schedule B. It lists each bank and how much it paid you.
Tax-free interest, like most municipal bond interest, goes on line 2a. You still report it, even though it isn't taxed.

Check each 1099-INT against your statements. If a bank sends a corrected form, use the new one.

Money market funds are different

A money market fund is a type of mutual fund that holds very short-term loans. It feels like savings, but what it pays you counts as dividends, not interest. You'll get a Form 1099-DIV for it. The tax rate is usually the same as interest. A money market account at a bank is different. It pays interest and gets a 1099-INT.

5. Treasuries and municipal bonds

Not all interest is taxed the same way.

Where the interest comes from	Federal tax	State and local tax
HYSA, CD, bank savings or money market account	Yes	Yes
U.S. Treasury bills, notes and bonds, I bonds, TIPS	Yes	No
Municipal bond from your own state	Usually no	Usually no
Municipal bond from another state	Usually no	Usually yes

A Treasury is a loan to the U.S. government. States and cities can't tax that interest. A municipal bond (or "muni") is a loan to a state or city. Most muni interest is free of federal tax, but most states tax munis from other states. A few muni bonds are federally taxable. The bond's paperwork will say so.

Watch out for bonds from Fannie Mae, Freddie Mac or Ginnie Mae. People often think they're Treasuries, but they aren't. States can tax that interest.

Choosing a Treasury over a CD can make sense in a high-tax state. Compare the rates after tax, not just the rates on the label.

6. Interest you aren't taxed on each year

Interest earned inside certain accounts isn't taxed year by year:

Traditional IRA and 401(k): no tax while the money stays in. You pay income tax when you take it out.
Roth IRA: no tax while it grows and no tax when you take it out, as long as you follow the Roth rules.
Health savings account (HSA): no tax while it grows and no tax on money you spend on medical care.

Example: Marcus has $10,000 in an HYSA and $10,000 in a cash option inside his Roth IRA. Both earn 4%, or $400 a year. He owes $88 on the HYSA interest at his 22% rate. The Roth's $400 isn't taxed at all if he follows the Roth rules.

7. Picking an account: look at what you keep

The highest APY doesn't always earn you the most. Fees can eat a small balance.

Example: Tasha has $2,000 saved. Bank A pays 4.25% but charges $5 a month. Bank B pays 4.00% with no fee.

Bank A: $85 of interest minus $60 of fees = $25
Bank B: $80 of interest, no fees

The "lower" rate earns her more than three times as much. She owes tax on the full $85 or $80 of interest either way.

Check safety too. FDIC insurance protects bank deposits up to $250,000 per person, per bank, per ownership type. Credit unions have the same protection through the NCUA. Our guides to HYSAs and CDs cover how to choose.

8. Plan ahead so April isn't a surprise

Banks don't withhold tax from interest. If you earn a lot of it, set some aside or adjust your paycheck withholding.

Set money aside. Multiply your expected interest by your top federal rate plus your state rate. Move that amount to a separate account.
Raise your withholding. File a new Form W-4 with your employer and add an extra amount per paycheck.
Make estimated payments. If you'll owe $1,000 or more when you file, you may need to pay the IRS during the year. Payments are due four times a year.

The Net Investment Income Tax (NIIT)

Higher earners pay one more tax on interest. The Net Investment Income Tax is an extra 3.8% on investment income, including interest. It only applies once your modified AGI passes $200,000 (single) or $250,000 (married filing jointly). Modified AGI is your adjusted gross income with a few items added back. These limits don't rise with inflation.

Example: Dev is single with $230,000 of modified AGI, including $5,000 of interest. He's $30,000 over the line, but the NIIT applies to the smaller number: his $5,000 of investment income. His NIIT is 3.8% × $5,000 = $190.

9. If you live in New York

New York State taxes bank interest as regular income, on top of federal tax.
New York City residents pay city income tax on that interest too. Yonkers residents pay a Yonkers surcharge.
Treasury interest is free of New York State and City tax. You still pay federal tax on it.
New York munis are usually free of federal, state and city tax. Munis from other states are taxed by New York.

Example: Ellen lives in NYC and earns $400 of interest. If it comes from a CD, she owes federal, New York State and NYC tax on it. If it comes from a Treasury bill, she owes only federal tax.

You can find New York's current rates from the New York State Department of Taxation and Finance.

Common mistakes

Thinking interest isn't taxed until you withdraw it. It's taxed the year it's added to your account.
Ignoring small accounts. No 1099-INT under $10 doesn't mean no tax. Report every dollar.
Getting surprised in April. Banks don't withhold. Set money aside or raise your withholding.
Forgetting the CD penalty deduction. If you paid an early-withdrawal penalty, deduct it.
Paying state tax on Treasury interest. Make sure your state return subtracts it.
Treating agency bonds like Treasuries. Fannie Mae, Freddie Mac and Ginnie Mae interest is taxed by your state.
Chasing the top APY without checking fees. On a small balance, a fee can wipe out the higher rate.

Frequently asked questions

Is HYSA interest tax-free if I keep it in the account?

No. Interest is taxed the year you earn it, whether you spend it or not.

Do I need a 1099-INT to owe tax?

No. Banks only have to send one at $10 or more. You still owe tax on smaller amounts.

Is APY my after-tax return?

No. APY is what the bank pays before taxes. At a 22% federal rate, a 4% APY leaves you about 3.1% after federal tax, and less after state tax.

Are all government bonds tax-free?

No. Treasury interest is taxed federally but not by states. Muni interest is usually free of federal tax. Interest from Fannie Mae, Freddie Mac and Ginnie Mae bonds is taxed by both.

Are CDs risk-free?

CDs at FDIC-insured banks are protected up to $250,000 per person, per bank, per ownership type. The real risks are inflation outpacing your rate and the penalty if you need the money early.

The bottom line

HYSA and CD interest is regular income, taxed the year it's added to your account. Banks don't withhold, so set money aside or adjust your W-4. Report every dollar, even without a 1099-INT. And if you live in a high-tax state like New York, compare after-tax rates with Treasuries before you choose.
