Quick Answer
Key Takeaways
- Interest from CDs and savings accounts is taxed as ordinary income at your federal marginal rate — 10% to 37% in 2026 — not at the lower long-term capital gains rates
- Savings interest is taxed in the year it is credited; multi-year CD interest is generally taxable each year as it accrues, even though you cannot withdraw it without a penalty
- This timing mismatch is the "phantom income" trap — you may owe tax on interest still locked inside a long-term CD
- Form 1099-INT reports interest paid or credited; Form 1099-OID reports accrued-but-unpaid interest on longer CDs that do not credit at least annually
- Banks issue a 1099 only when interest reaches $10, but all interest is reportable to the IRS
- Most states tax CD and savings interest too; U.S. Treasury bills are exempt from state and local tax, which can flip the after-tax winner for high-tax-state savers
- Holding CDs inside an IRA defers or eliminates the annual tax and stops the 1099 entirely
How is CD and savings account interest taxed? The short answer: as ordinary income, at the same federal rate you pay on your wages. There is no preferential "interest" rate — a saver in the 24% bracket who earns $1,000 of CD interest owes about $240 in federal tax, plus state tax in most states. The surprise for many savers is the timing. Savings account interest is easy: you are taxed the year it lands in your account. But a multi-year CD can generate a tax bill before you can spend a dime of it, because the IRS taxes the interest as it is credited each year, not when the CD matures. That gap is the focus of this guide.
The Core Rule: Interest Is Ordinary Income
Both CD and savings account interest are taxable interest income under IRS Topic No. 403, Interest Received(opens in new tab). Taxable interest is added to your other income (wages, business income, etc.) and taxed at your marginal ordinary-income rate. Unlike qualified dividends or long-term capital gains, interest never qualifies for the lower 0%/15%/20% rates.
The 2026 ordinary-income brackets, per the IRS inflation adjustments for tax year 2026(opens in new tab), are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Where your interest falls depends on your total taxable income — interest stacks on top of your wages, so the first dollar of CD interest is taxed at your highest bracket.
How Much Tax You Actually Owe
The table below shows the federal tax on $1,000 of CD or savings interest at each 2026 bracket, and the after-tax amount you keep. State tax is additional in most states.
| 2026 Marginal Bracket | $1,000 Interest | Federal Tax | After-Tax Kept |
|---|---|---|---|
| 10% | $1,000 | $100 | $900 |
| 12% | $1,000 | $120 | $880 |
| 22% | $1,000 | $220 | $780 |
| 24% | $1,000 | $240 | $760 |
| 32% | $1,000 | $320 | $680 |
| 35% | $1,000 | $350 | $650 |
| 37% | $1,000 | $370 | $630 |
A real-world frame: a $40,000 CD at 4.10% APY (a representative top 1-year rate in June 2026) earns about $1,640 in its first year. In the 24% bracket, roughly $394 of that goes to federal tax, leaving an after-tax yield closer to 3.12%. Add a 5% state income tax and the after-tax yield drops to about 2.92%. After-tax yield — not the headline APY — is what actually grows your money.
When You Owe: Savings Accounts vs. CDs
The tax rate is identical for both products. The tax timing is where they diverge.
Savings Accounts: Taxed When Credited
High-yield and traditional savings account interest is credited monthly and is available to withdraw at any time. Because you can access it freely, the IRS taxes it in the year it is credited — simple and intuitive. If your HYSA pays $600 of interest in 2026, you report $600 of taxable interest on your 2026 return.
CDs: Taxed As Interest Accrues
Here is the part that surprises savers. For most CDs, you owe tax on the interest each year it accrues, regardless of whether the CD has matured. The IRS rule, summarized in Topic 403, is that interest "credited to an account that you can withdraw from" is taxable when available — but for CDs, the IRS treats annually credited interest as available for tax purposes even when an early-withdrawal penalty applies.
The result depends on the CD term:
- CD term of 1 year or less: Interest is often credited and taxed in a single year — usually at maturity. Clean and simple.
- CD term longer than 1 year that credits interest at least annually: You receive a Form 1099-INT each January for the prior year's credited interest, and you owe tax on it every year — even though breaking the CD to access that interest would trigger a penalty.
- CD term longer than 1 year that does NOT credit interest at least annually: The interest is treated as Original Issue Discount (OID), reported on Form 1099-OID, and is still taxable each year.

The "Phantom Income" Trap on Multi-Year CDs
Combine the two rules above — interest taxed as it accrues, plus an early-withdrawal penalty to access it — and you get the classic multi-year CD problem: you owe tax on money you cannot spend without a penalty. This is widely called "phantom income."
Consider a $50,000 5-year CD at 4.15% APY that compounds and pays all interest at maturity. Even though you receive no cash until year 5, the IRS expects you to report and pay tax on the interest that accrues each year:
| Year | Interest Accrued | Cash Received | Federal Tax Owed (24%) |
|---|---|---|---|
| Year 1 | ~$2,075 | $0 | ~$498 |
| Year 2 | ~$2,161 | $0 | ~$519 |
| Year 3 | ~$2,251 | $0 | ~$540 |
| Year 4 | ~$2,344 | $0 | ~$563 |
| Year 5 (maturity) | ~$2,442 | ~$61,273 total | ~$586 |
In years 1 through 4, you owe roughly $2,120 in cumulative federal tax on interest you have not received and cannot withdraw without a penalty. You must cover that tax from other cash. Only at maturity does the CD actually pay out.
Plan for the Cash to Pay the Tax
The phantom-income trap is a liquidity problem, not a tax-rate problem. Before locking a large multi-year CD that pays at maturity, confirm you will have cash available each April to pay the accruing-interest tax. If you may need that interest income to live on, choose a CD that pays interest out monthly or quarterly, or use a CD ladder so a portion matures (and pays out) every year.
Form 1099-INT vs. Form 1099-OID: Which You Get and Why
Two different IRS forms report cash interest. Knowing which applies tells you how and when the tax hits.
| Feature | Form 1099-INT | Form 1099-OID |
|---|---|---|
| What it reports | Interest paid or credited during the year | Interest accrued but not paid (Original Issue Discount) |
| Typical product | Savings accounts; CDs that credit interest at least annually | CDs over 1 year that do NOT credit interest at least annually |
| Key box | Box 1 (taxable interest); Box 2 (early-withdrawal penalty) | Box 1 (OID to report as income) |
| Issued when | $10 or more of interest for the year | $10 or more of OID for the year |
| Taxed how | Ordinary income, each year | Ordinary income, each year |
Both forms point to the same outcome — ordinary income taxed annually. The reporting mechanics are detailed in the IRS guidance on Form 1099-INT(opens in new tab) and Form 1099-OID(opens in new tab).
No 1099 Does Not Mean No Tax
Banks only issue a 1099 once interest reaches $10. If you earned $8 of interest on a small account, you will not get a form — but the IRS still requires you to report that $8 as taxable interest. Keep your December statements; they show the credited interest even when no tax form arrives.
State Tax: Where CDs Lose to Treasury Bills
Federal tax is only half the picture. Most states tax CD and savings interest as ordinary income at the state level. The exceptions are the no-income-tax states: Florida, Texas, Nevada, Washington, Wyoming, South Dakota, Alaska, and Tennessee.
This is where U.S. Treasury bills have a structural edge. Interest on Treasury bills, notes, and bonds is exempt from all state and local income taxes — only federal tax applies. For a saver in a high-tax state, a Treasury yielding slightly less than a CD can still win on an after-tax basis.
After-Tax Comparison: 4.10% CD vs. 4.05% T-Bill (California, 24% Federal)
| Instrument | Stated APY/Yield | Federal Tax (24%) | CA State Tax (9.3%) | After-Tax Yield |
|---|---|---|---|---|
| 1-Year CD | 4.10% | Applies | Applies | ~2.73% |
| 1-Year T-Bill | 4.05% | Applies | Exempt | ~3.08% |
Despite a lower stated yield, the Treasury bill delivers a higher after-tax return for this saver because its interest escapes the 9.3% California tax. In a no-income-tax state, the CD's higher headline rate would win instead. The lesson: always compare cash instruments on after-tax yield, factoring in your state. For variable-rate cash, our High-Yield Savings guide covers how HYSA rates move with the Fed.
Three Legitimate Ways to Cut the Tax on Cash Interest
You cannot make CD or savings interest tax-free in a regular taxable account, but you can reduce the drag.
1. Hold CDs Inside an IRA
An IRA CD shelters the interest from annual tax entirely. In a Traditional IRA the interest grows tax-deferred until withdrawal; in a Roth IRA it can grow and be withdrawn tax-free in retirement. Either way, the bank issues no annual 1099-INT or 1099-OID for the CD, which eliminates the phantom-income problem. The tradeoff is that IRA funds are subject to retirement-account withdrawal rules. See our IRA Calculator to weigh Traditional vs. Roth.
2. Prefer Treasuries in High-Tax States
As shown above, the state-tax exemption on Treasury bills can outweigh a small yield disadvantage versus a CD. For taxable cash you are confident you will not need to touch, a T-bill ladder is often the more tax-efficient choice in California, New York, New Jersey, and other high-tax states.
3. Time Short-Term CDs Into a Lower-Income Year
A CD of 1 year or less that pays all interest at maturity lets you choose which tax year absorbs the income. If you expect a lower-income year — a sabbatical, a gap between jobs, early retirement before Social Security — maturing a CD in that year taxes the interest at a lower bracket.
Don't Forget the Early-Withdrawal Penalty Deduction
If you do break a CD early, the early-withdrawal penalty (Box 2 of your 1099-INT) is deductible above-the-line on Schedule 1 — even if you take the standard deduction. It directly reduces your taxable income. Full details in our CD Early Withdrawal Penalty guide.
Reporting Interest on Your 2026 Return: A Checklist
- Collect every 1099-INT and 1099-OID by late January / early February. Banks must furnish them by January 31.
- Add up all taxable interest, including amounts under $10 with no form. Use your December statements to catch interest the bank did not report.
- Report on Form 1040, Line 2b (taxable interest). If your total taxable interest exceeds $1,500, you must also complete Schedule B.
- List the early-withdrawal penalty (1099-INT Box 2) on Schedule 1, Line 18, if you broke a CD.
- Check your withholding or estimates. If interest pushes your total tax up materially, you may need quarterly estimated payments to avoid an underpayment penalty — this is especially relevant for phantom income on large CDs.

Frequently Asked Questions
Usually, yes. For most multi-year CDs, the IRS treats interest as taxable in the year it is earned and credited, even though you cannot withdraw it without an early-withdrawal penalty. Your bank reports the annual credited interest on Form 1099-INT, Box 1. The only common exception is a CD with a term of 1 year or less, where all the interest may be credited at maturity and taxed in that single year. If a CD has a term longer than one year and does not credit interest at least annually, the interest is reported as Original Issue Discount (OID) on Form 1099-OID and is still taxable each year. This is sometimes called the "phantom income" problem because you owe tax on interest you have not yet received in cash. Use our CD Calculator to project the interest you will accrue each year.
Interest from a high-yield or traditional savings account is taxed as ordinary income at your marginal federal tax rate, which ranges from 10% to 37% in 2026. Because savings interest is credited and available to withdraw at any time, it is taxable in the year it is credited to your account. Your bank issues Form 1099-INT (Box 1) if you earned $10 or more in interest during the year, but you must report all taxable interest even if you do not receive a 1099-INT. Most states that levy an income tax also tax savings interest at the state level.
Form 1099-INT reports interest that was actually paid or credited to your account during the year — for example, a savings account or a CD that credits interest monthly, quarterly, or annually. Form 1099-OID (Original Issue Discount) is issued when a CD has a term longer than one year and does not credit interest at least once a year; the bank calculates the interest you accrued each year and reports it as OID, which you must include in income even though no cash was paid out. Both forms result in interest taxed as ordinary income. The practical difference is that 1099-OID is the form most associated with the phantom-income trap on long-term, non-distributing CDs.
In most states, yes. CD and savings account interest is taxed as ordinary income at the state level wherever a state income tax applies. The exceptions are the no-income-tax states — Florida, Texas, Nevada, Washington, Wyoming, South Dakota, Alaska, and Tennessee — where interest income is not taxed by the state. This is a key difference from U.S. Treasury bills and notes, whose interest is exempt from all state and local income taxes. For savers in high-tax states like California, New York, or New Jersey, the state-tax exemption can make a Treasury yielding slightly less than a CD a better after-tax choice.
Several strategies can lower the tax drag on cash interest. First, hold CDs inside a tax-advantaged account such as an IRA CD, where interest grows tax-deferred (Traditional) or tax-free (Roth) and no annual 1099 is issued. Second, for taxable accounts in high-tax states, compare CDs against U.S. Treasury bills, whose interest is exempt from state and local tax. Third, for short-term needs, consider that a 12-month-or-shorter CD that credits all interest at maturity can shift the entire tax hit into a single year you choose. Finally, if you break a CD early, remember the early-withdrawal penalty is deductible above-the-line on Schedule 1. None of these eliminate federal tax, but they can meaningfully improve after-tax yield. Consult a tax professional for your situation.
Yes. Banks are only required to issue Form 1099-INT or 1099-OID when interest reaches $10 for the year, but the IRS requires you to report all taxable interest regardless of whether you receive a form. If you earned $8 of interest on a small CD or savings account, no 1099 is generated, yet that $8 is still taxable interest income that belongs on your return. Keep your year-end account statements; they show the interest credited even when the bank does not send a tax form.
