CD interest is taxed as ordinary income — at the same federal rate as your wages, not the lower capital gains rate. It is reported on Form 1099-INT and must be included on your federal tax return for the year it is credited, even if you don’t access the money until the CD matures.

The most important rule many savers miss: For multi-year CDs, you may owe taxes on interest each year even though the CD hasn’t matured.

The Core Tax Rules for CDs

Rule Detail
Tax rate Ordinary income (federal + state/local where applicable)
Reporting form Form 1099-INT (issued by bank each January)
When taxed Year interest is credited — not year of withdrawal
Capital gains rate Does not apply to CD interest
Minimum to report $10 or more from a single institution
State tax Most states tax CD interest as ordinary income
Exception CDs in a traditional or Roth IRA (IRA tax rules apply instead)

Ordinary Income Rate vs. Capital Gains Rate

CD interest is taxed at the ordinary income rate — your marginal federal tax bracket:

Filing Status 2026 Taxable Income Federal Tax Rate on CD Interest
Single Up to $11,925 10%
Single $11,925–$48,475 12%
Single $48,475–$103,350 22%
Single $103,350–$197,300 24%
Single $197,300–$250,525 32%
Single Over $250,525 35–37%

For comparison, long-term capital gains rates top out at 20% for high earners. CD interest does not qualify for the preferential capital gains rate.

When Multi-Year CDs Create a Tax Surprise

For a 12-month CD, the tax is simple: interest is credited at maturity, reported in that calendar year, and taxed once.

For a 2-year, 3-year, or 5-year CD, the situation is more complex:

Scenario: You open a 3-year CD on May 21, 2026 at 4.25% APY with $20,000. Interest compounds annually:

Year Interest Credited Tax Due That Year
2026 (partial) ~$347 Due on 2026 return
2027 ~$898 Due on 2027 return
2028 ~$936 Due on 2028 return
2029 (partial) ~$395 Due on 2029 return

You owe tax on CD interest each year as it accrues — even though the CD doesn’t mature until May 2029 and you cannot touch the money. Your bank will send a Form 1099-INT each January covering that year’s credited interest.

Cash flow implication: You need cash from other sources to pay the tax each year, since you cannot withdraw from the CD. This is a key reason some savers prefer short-term CDs or hold long-term CDs inside an IRA.

Form 1099-INT: What to Expect

Your bank sends Form 1099-INT to you and to the IRS by January 31 each year. It reports:

  • Box 1: Interest income from CDs and savings accounts
  • Box 3: US savings bond/Treasury interest (state tax exempt)
  • Box 8: Tax-exempt interest (municipal bonds — not applicable to CDs)

Enter the Box 1 amount on Schedule B of your Form 1040. If your total interest and dividend income is under $1,500, you do not need to file Schedule B — you can enter it directly on Form 1040 Line 2b.

If you do not receive a 1099-INT but earned $10 or more in CD interest, you are still required to report it.

State Taxes on CD Interest

Most US states tax CD interest as ordinary income at the state level. Exceptions:

  • No income tax states (Florida, Texas, Nevada, Washington, Wyoming, South Dakota, Alaska, New Hampshire on wages): No state income tax on CD interest
  • New Hampshire: Taxes interest and dividends above a threshold (phase-out in progress)

For high-income earners in high-tax states (California 13.3%, New York 10.9%, New Jersey 10.75%), Treasury bills may offer better after-tax returns since T-bill interest is exempt from state and local taxes. See CDs vs Treasury bills 2026.

How to Reduce CD Tax Liability Legally

1. Hold CDs in a Traditional IRA

Interest grows tax-deferred. You owe no tax until withdrawal in retirement — when your tax rate may be lower.

2. Hold CDs in a Roth IRA

Interest grows completely tax-free. Qualified withdrawals (after 59½, 5-year holding period) are never taxed on CD interest.

IRA CD contribution limits for 2026:

  • Under age 50: $7,000/year total IRA contributions
  • Age 50+: $8,000/year (catch-up contribution)

See IRA vs CD 2026 for full details.

3. Use I Bonds Instead (for eligible savers)

Series I Savings Bonds allow you to defer federal tax until redemption and are exempt from state tax. Limits: $10,000/year per SSN directly from the Treasury.

4. Choose Shorter CD Terms

Short-term CDs mature sooner, meaning interest is credited all at once in one year rather than spread across multiple years. This can simplify tax timing but doesn’t reduce the total tax owed.

CD Interest Reporting: Checklist

  • Expect a Form 1099-INT from each bank where you earned $10+ in interest
  • Report interest on Schedule B if total interest + dividends exceed $1,500
  • For multi-year CDs, watch for annual 1099-INT even before maturity
  • Add CD interest to Form 1040 Line 2b
  • Consider state tax impact — CD interest is generally state-taxable
