Quick Answer
Yes — every dollar your savings account, CD, or money market account pays you in interest is taxable income. The IRS treats it exactly like income from a job, taxed at your regular federal rate (somewhere between 10% and 37%, depending on how much you make overall).
If any single bank paid you $10 or more during 2025, you’ll get a Form 1099-INT by early February 2026 — and you owe tax on every dollar of interest you earned, whether a form shows up or not.
Quick disclaimer: I’m not a CPA, and nothing here is personalized tax advice — just a clear breakdown based on current IRS and Treasury rules. For anything specific to your own return, a real tax professional is worth the call.
Quick Summary
- ✓Yes, it’s taxable. Interest from savings accounts, HYSAs, CDs, and money market accounts counts as ordinary income — taxed at the same federal rates as your paycheck (10%–37% for 2025).
- ✓There’s no special “savings tax rate.” Your interest gets stacked on top of your other income and taxed at whatever bracket(s) it falls into.
- ✓The $10 rule is about paperwork, not taxes. Banks must send a Form 1099-INT if they paid you $10 or more — but every dollar of interest is technically taxable, form or no form.
- ✓$1,500 is the Schedule B trigger. If your total taxable interest from all accounts combined tops $1,500, you’ll need to attach Schedule B to your return.
- ✓Most states tax it too. Only nine states — including Texas, Florida, and, as of 2025, New Hampshire — skip state income tax on savings interest entirely.
- ✓Bank bonuses count. That $300 you got for opening a new checking account? Taxed the same as interest.
- ✓High earners may owe extra. Once your income passes $200,000 (single) or $250,000 (married filing jointly), an additional 3.8% Net Investment Income Tax can kick in.
- ✓You’ve got options. Roth IRAs, HSAs, I bonds, 529 plans, and the brand-new “Trump Accounts” for kids all offer better tax treatment for at least part of your savings.
Wait, So My Savings Interest Really Gets Taxed Like a Paycheck?
Yep — and once you understand the IRS’s reasoning, it stops feeling quite so unfair.
The logic is simple: income is income. It doesn’t matter whether it came from your employer, a side hustle, or your bank quietly crediting interest to your account every month. If money came to you and it wasn’t a gift, a loan, or one of a handful of specific exceptions, the IRS counts it.
For savings accounts, that interest falls into a category called “ordinary income” — the same bucket as your wages, your tips, and your freelance income. Which means it’s taxed at your regular federal income tax bracket, not some lower “investment” rate.
Real-Life Example
Take Maria, a nurse in Austin. In January 2025, she moved her $25,000 emergency fund into an online high-yield savings account paying 4.5% APY. By December, that account had quietly earned her about $1,125 in interest.
Here’s the part that catches people off guard: Maria never touched that money. Not a single dollar. It just sat there, compounding while she went about her life. Doesn’t matter. As far as the IRS is concerned, that $1,125 is 2025 taxable income — the same as if her employer had handed her an extra $1,125 bonus.
What Counts as “Savings Account Interest,” Exactly?
For tax purposes, the IRS lumps together pretty much anything a bank or credit union pays you for keeping your money with them:
- ›Regular savings accounts
- ›High-yield savings accounts (HYSAs)
- ›Money market deposit accounts
- ›Certificates of deposit (CDs)
- ›Interest-bearing checking accounts
- ›Credit union “dividends” (which, tax-wise, are really just interest with a different name)
If your statement shows it as “interest paid” or “dividends earned,” it’s almost certainly taxable the same way.
“Ordinary Income” vs. the Tax Breaks Other Investments Get
This is the part that throws people who also have a brokerage account or retirement portfolio, because not all investment income gets treated the same way.
Sell a stock you’ve held for more than a year at a profit, and that’s a long-term capital gain — taxed at special rates of 0%, 15%, or 20% depending on your income. Qualified dividends get the same treatment. The tax code basically says, “thanks for investing — here’s a discount.”
Your savings account interest gets none of that. It lands squarely in the “ordinary income” pile, taxed at the same rates as your salary.
Key point: There’s no such thing as a special “savings account tax rate.” Whatever bracket your last dollar of income falls into — that’s the rate your interest gets taxed at too.
The 2025 Federal Income Tax Brackets (For Returns Filed in Early 2026)
Here’s the full picture for tax year 2025 — what most people are working with as they read this:
| Tax Rate | Single Filers | Married Filing Jointly |
|---|---|---|
| 10% | $0 – $11,925 | $0 – $23,850 |
| 12% | $11,925 – $48,475 | $23,850 – $96,950 |
| 22% | $48,475 – $103,350 | $96,950 – $206,700 |
| 24% | $103,350 – $197,300 | $206,700 – $394,600 |
| 32% | $197,300 – $250,525 | $394,600 – $501,050 |
| 35% | $250,525 – $626,350 | $501,050 – $751,600 |
| 37% | $626,350 and up | $751,600 and up |
Quick refresher on how brackets actually work: if you’re single with $75,000 in taxable income, you’re “in” the 22% bracket — but the IRS isn’t taking 22% of all $75,000. Only the slice above $48,475 gets taxed at 22%. Everything below that is taxed at the lower rates, layer by layer. Your interest generally lands at the top of this stack, taxed at your highest marginal rate.
So How Much Could $1,000 (or $5,000) in Interest Actually Cost You?
| Your Situation (2025) | Federal Bracket | Tax on $1,000 | Tax on $5,000 |
|---|---|---|---|
| Single, ~$35,000 taxable income | 12% | $120 | $600 |
| Single, ~$75,000 taxable income | 22% | $220 | $1,100 |
| Single, ~$150,000 taxable income | 24% | $240 | $1,200 |
| Married filing jointly, ~$90,000 | 12% | $120 | $600 |
| Married filing jointly, ~$180,000 | 22% | $220 | $1,100 |
| Married filing jointly, ~$350,000 | 24% | $240 | $1,200 |
| Single, ~$260,000 (+ NIIT) | 35% + 3.8% = 38.8% | $388 | $1,940 |
Federal numbers only — your state may take another bite. These assume interest lands cleanly within one bracket rather than straddling a line.
Form 1099-INT, Explained Without the Jargon
Form 1099-INT is your bank’s way of telling both you and the IRS exactly how much interest it paid you last year.
When (and How) Will You Get It?
Any bank, credit union, or brokerage that paid you $10 or more in interest during 2025 has to send you a 1099-INT by early February 2026 (the official deadline is January 31, which falls on a Saturday in 2026, pushing it to February 2).
Heads Up
Many online banks don’t mail these anymore. If your high-yield savings account lives at an online-only bank, your 1099-INT is probably waiting in a “Tax Documents” or “Statements” tab inside your account — not your mailbox. Worth a login in late January just to check.
What If You Have Accounts at Several Banks?
You’ll get a separate 1099-INT from each bank that paid you $10 or more. If you’ve been chasing the best APYs across three or four online savings accounts — smart, by the way — you might end up with a small stack of these. Add up Box 1 (“Interest Income”) from every single one. That combined total is what goes on your return.
The IRS Already Has This Info — So Don’t Skip It
Every 1099-INT a bank sends you, it also sends to the IRS. Their systems automatically match what banks report against what you report. If something doesn’t line up — say you forgot about $43 from an old account — the IRS’s matching system typically catches it within a year or two and sends a notice (usually called a CP2000) asking for the extra tax, plus interest.
It’s rarely a disaster, but it’s a completely avoidable hassle. Double-checking now beats a letter from the IRS eighteen months from now.
The Two Lines on Your Return That Actually Matter
|
Form 1040, Line 2b “Taxable Interest” Your total interest income from every 1099-INT goes here. Tax software typically has you enter each form and adds them up for you. |
Schedule B Only If You Need It Only required if your total taxable interest (or dividends) for the year is over $1,500. Under that? You can skip it entirely. |
“I Only Earned $6.42 — Do I Really Have to Report That?”
Technically, yes. I know that sounds a little absurd, so let’s unpack why.
The $10 threshold for Form 1099-INT is a rule for banks, not for you. It tells banks when they’re required to send paperwork — it says nothing about whether the income itself is taxable. Every dollar (and every cent) of interest you earn is taxable in the eyes of the IRS, whether it’s $6.42 or $6,420.
Real-Life Example
Meet Jake, from Columbus, Ohio — a bit of a rate-chaser with savings accounts open at six different online banks. None of those six accounts individually earned him $10 in interest, so he received zero 1099-INT forms. But when he added up the interest from each account’s year-end statement, the total came to $38.
Technically, Jake owes tax on that $38. It takes about thirty seconds to add a line in your tax software — no 1099 required — and “technically taxable but probably won’t get noticed” isn’t really a strategy. It’s just a small, completely unnecessary risk.
Does Your State Want a Cut Too?
Here’s where things get a little more “it depends.”
Most states use your federal Adjusted Gross Income (AGI) as the starting point for their own return. So if your savings interest is part of your federal AGI — which it is — it’s automatically part of your state taxable income too, unless your state specifically carves out an exception (most don’t, for savings interest).
The 9 States Where Savings Interest Isn’t Taxed at All
As of 2025, nine states have no broad-based individual income tax — which means no state tax on your savings interest, either:
AlaskaFloridaNevadaNew Hampshire ★ New 2025South DakotaTennesseeTexasWashingtonWyoming
New Hampshire Update — 2025
For decades, New Hampshire taxed interest and dividend income — at rates that had been stepping down from 5% to 4% to 3% over a few years. As of January 1, 2025, that tax (officially the “Interest and Dividends Tax”) was fully repealed. If you’re a New Hampshire resident, your savings account interest is now completely free of state tax — for the first time in more than a century.
If you live in one of the other 41 states (or DC), your savings interest is very likely taxed as part of your regular state income. State rates vary enormously — from under 3% in some states to north of 13% in a few others.
Wait — Are Bank Sign-Up Bonuses Taxable Too?
Yes, and this one trips people up every single year.
You’ve seen the ads: “Open a checking account, set up direct deposit, and we’ll give you $300!” It feels like a gift — free money for doing basically nothing. The IRS sees it differently.
Real-Life Example
Devon, a teacher in Phoenix, opened a new checking account in early 2025 to grab a $300 new-account bonus. He met the requirements — direct deposit, a minimum balance held for 90 days — and the $300 landed in his account that March.
Come tax season, Devon got a 1099-INT (some banks issue a 1099-MISC instead) listing that $300. The IRS treats bank account bonuses as interest — compensation for the “privilege” of using your money. That $300 gets added to Devon’s income and taxed at his regular rate, exactly like savings account interest.
Important distinction: Credit card sign-up bonuses and cash-back rewards are usually treated differently — generally as a discount or rebate rather than income, as long as you had to spend money to earn them. Bank account opening bonuses, on the other hand, are consistently treated as taxable interest. Different product, different rules.
The Extra Tax High Earners Should Know About
If your income is comfortably into six figures, there’s one more wrinkle worth knowing about: the Net Investment Income Tax (NIIT).
NIIT adds an extra 3.8% on top of your regular rate — but only on investment income (interest, dividends, capital gains, rental income, and similar), and only once your Modified Adjusted Gross Income (MAGI) crosses $200,000 if you’re single, or $250,000 if you’re married filing jointly. These thresholds haven’t been adjusted for inflation in over a decade, so more people cross them every year as incomes climb.
|
3.8% Extra rate on investment income |
$200K MAGI threshold (single filers) |
$250K MAGI threshold (married filing jointly) |
Real-Life Example
Priya, a software engineer in Seattle, has a MAGI of around $230,000 — over the $200,000 single threshold. She keeps $40,000 in a HYSA, earning roughly $1,800 a year in interest.
That $1,800 gets taxed at her marginal federal rate of 32% ($576) plus an extra 3.8% NIIT ($68.40). All told, Priya’s “passive” $1,800 in interest costs her about $644 in federal tax alone — an effective rate of nearly 36% on money she didn’t lift a finger to earn. And that’s before her state even gets involved.
So Where Else Could This Money Go?
None of this means you should stop earning interest on your savings — to be clear. An emergency fund earning 4%+ in a taxable HYSA, even after taxes, still beats an emergency fund earning 0.01% in a “free checking” account every single time.
But if you’re sitting on more cash than your emergency fund actually needs, it’s worth knowing where interest and growth get friendlier tax treatment.
How to Report Your Savings Interest, Step by Step (and Plan Smarter for Next Year)
Here’s exactly what to do, start to finish:
Round up every 1099-INT. Check your email and log into every bank where you held a savings account, CD, or money market account during 2025 — a lot of online banks deliver these electronically only, usually by early February.
Don’t forget the accounts that didn’t send a form. Earned under $10 somewhere? You won’t get a 1099-INT — but pull up that account’s December or year-end statement and note the interest anyway.
Add it all up. Combine Box 1 (“Interest Income”) from every 1099-INT, plus any small amounts from accounts that didn’t issue one. This total is your taxable interest for the year.
Enter the total on Form 1040, Line 2b. Tax software will typically walk you through entering each 1099-INT individually and total them automatically.
Check whether you need Schedule B. Over $1,500 total? Attach Schedule B, listing each bank and the amount it paid you. Under $1,500? Skip it.
Don’t forget your state return. Unless you’re in one of the nine no-income-tax states, this interest is likely flowing into your state return as part of your AGI automatically — but it’s worth a quick check, especially if you moved states during the year.
File, then file away your paperwork. Hang onto your 1099-INTs and account statements for at least three years — the IRS’s typical window for follow-up questions.
Now, look ahead. Before next year rolls around, take stock: is some of this cash sitting in a taxable HYSA when it could be working harder in a Roth IRA, HSA, or I bond instead? You don’t need to move everything — just the portion you really won’t touch for a while. A little intentional placement now can mean a noticeably smaller tax bill next April.
Savings Interest vs. Everything Else: Side-by-Side
Here’s how the most common places to park cash compare, tax-wise:
| Where Your Cash Sits | How It’s Taxed | When You Pay | Best For |
|---|---|---|---|
| Savings account / HYSA | Ordinary income (10%–37% federal, plus state) | Every year, as credited | Emergency funds, short-term cash |
| Certificate of deposit (CD) | Ordinary income | Each year interest posts — even on multi-year CDs | Locking in today’s rate |
| Money market account | Ordinary income | Every year, as credited | Slightly higher yield, still liquid |
| Series I savings bonds | Federal ordinary income; state/local tax-free | Deferred until cashed in | Long-term, inflation-protected |
| Municipal bonds / funds | Federally tax-exempt (often state-exempt too) | N/A — no federal tax due | Higher-bracket investors |
| Roth IRA | Tax-free growth and qualified withdrawals | Never, if qualified | Long-term retirement savings |
| Traditional IRA / 401(k) | Tax-deferred | At withdrawal, as ordinary income | Retirement with upfront deduction |
| HSA | Tax-free for qualified medical expenses | Never, if used for medical costs | Healthcare costs + backup retirement |
| 529 plan | Tax-free for qualified education expenses | Never, if used for education | College savings |
| Trump Account (new, for kids) | Tax-deferred | At withdrawal after 18, as ordinary income | Long-term savings for a child’s future |
The short version: your everyday savings, CDs, and money market accounts are the most flexible and accessible — but also the most exposed to taxes, every single year. Everything else on that list trades away a bit of flexibility for noticeably better long-term tax treatment. See also: saving vs. investing and how to build an emergency fund.
Frequently Asked Questions
The Bottom Line
Earning interest on your savings is a good thing. It means your money is finally doing something, instead of sitting in an account paying next to nothing. The tax bill that comes with it isn’t a penalty for being smart with your cash — it’s just the IRS treating that interest the same as any other income.
The goal isn’t to avoid earning interest. The goal is to know it’s coming so it doesn’t surprise you in April, report it accurately so you’re not dealing with a notice eighteen months from now, and start thinking about whether some of that cash might be better off in a Roth IRA, HSA, or I bond — not instead of your savings account, but alongside it.
One more time, because it matters: this guide is built from current IRS rules and Treasury data, but it’s general information, not advice tailored to your specific return. If your taxes involve multiple states, a big bonus or bank promo, custodial accounts for kids, or anything beyond “a job and a savings account,” a real conversation with a tax professional is worth the cost. Future you will thank present you.
