IRA CD Ladder Strategy: How to Build One Inside Your IRA
CD vs MYGA, after tax
What $100,000 earns in 5 years: CD vs MYGA, after tax
Rates used: CD 4.50%, the top nationally available 5-year CD (DepositAccounts, September 24, 2026); change it to the rate you are offered. MYGA 5.95%, the best A-rated rate we track as of October 13, 2026: Delaware Life Pinnacle Plus 5-year (AM Best A-, negative outlook, 7/31/2026), $100,000 and up, effective October 6, 2026 (Delaware Life rate sheet).
| CD, interest taxed every year | $118,826 |
|---|---|
| MYGA, tax-deferred, before tax | $133,507 |
| MYGA after paying tax on all the interest at withdrawal | $126,136 |
| Tax deferral alone adds about | $674 |
| MYGA ahead of the CD, after tax | $7,310 |
Assumes 22% federal and 0% state income tax, no withdrawals, rates held for the whole term. MYGA interest is taxed as ordinary income when you withdraw it, not as capital gains. Gains taken before age 59 1/2 can owe a 10% IRS penalty, and cashing out early can cost a surrender charge. In an IRA both grow tax-deferred, so the edge there is the rate alone. Bank and credit union deposits are FDIC or NCUA insured up to the limits; a MYGA is backed by the issuing insurer's claims-paying ability and your state's guaranty association up to its limits, not the FDIC. General education, not tax, legal or financial advice.
How an IRA CD ladder works
You take a single IRA balance and split it across multiple CDs with different maturity dates. The classic 5-year ladder:
- Rung 1: 20% in a 1-year IRA CD
- Rung 2: 20% in a 2-year IRA CD
- Rung 3: 20% in a 3-year IRA CD
- Rung 4: 20% in a 4-year IRA CD
- Rung 5: 20% in a 5-year IRA CD
Each year, one rung matures. You reinvest that maturity into a new 5-year CD. After 5 years, the ladder has stabilized into 5 staggered 5-year CDs, each maturing one year apart. You always have 20% of the balance maturing within 12 months, which is useful for RMDs, opportunistic redeployment, or genuine emergencies.
The tax-free reinvestment advantage inside an IRA
This is the key feature of an IRA ladder. When a taxable CD matures and you reinvest, the interest earned is reported on a 1099-INT for that year and is taxable in the year credited. Across a 5-rung ladder rolling annually, you have a continuous tax drag every year.
Inside an IRA, the entire reinvestment cycle is tax-free during the holding period. The maturity proceeds (principal + interest) stay inside the IRA wrapper. No 1099-INT is issued. You only owe tax when you eventually take a withdrawal from the IRA, not when the rungs mature and reinvest.
For Traditional IRAs, this means the ladder compounds tax-deferred forever (until withdrawal or RMD). For Roth IRAs, it compounds tax-free forever (subject to qualified-distribution rules at withdrawal).

Step-by-step: build a 5-year IRA CD ladder with $250,000
- Open an IRA (Traditional, Roth, or use existing) at your chosen bank, credit union, or brokerage. Most major institutions allow multiple CDs inside one IRA wrapper. You do not need 5 separate IRAs.
- Fund the IRA via direct rollover from your 401(k), trustee-to-trustee transfer from another IRA, or new contributions (subject to annual limits).
- Open 5 CDs simultaneously:
- $50,000 in a 12-month IRA CD at ~4.65% APY
- $50,000 in a 24-month IRA CD at ~4.50%
- $50,000 in a 36-month IRA CD at ~4.35%
- $50,000 in a 48-month IRA CD at ~4.20%
- $50,000 in a 60-month IRA CD at ~4.10%
- At month 12, the first $50K matures (now worth ~$52,325). Reinvest into a new 60-month IRA CD at whatever the prevailing rate is at that time.
- Repeat annually. After 5 years, all rungs are 5-year CDs maturing one per year.
Where to physically build the ladder
Three structural options:
- Single bank, multiple CDs in one IRA. Easiest to manage. Marcus, Synchrony, Ally, Discover, Capital One all allow multiple IRA CDs in one IRA wrapper. Trade-off: all rungs at one bank means you are concentrated for FDIC purposes if balance exceeds $250K.
- Multiple banks, separate IRAs. Stack FDIC coverage by splitting across institutions. More paperwork, more 1099-R forms at distribution time, but cleaner protection at large balances.
- Brokered CDs inside one brokerage IRA. Fidelity or Schwab IRA brokered CD inventory lets you build a 5-rung ladder across 5 different issuing banks in one transaction. FDIC stacks across the issuers, all administered inside one IRA. This is the cleanest approach for $250K+ ladders.
How IRA CD taxation actually works
This is the single most misunderstood point. An IRA CD is taxed like any other IRA asset, not like a taxable bank CD.
- Inside a Traditional IRA: Interest credited each year is not reported on your 1040. You do not get a 1099-INT for IRA CD interest. The CD compounds tax-deferred. You only owe tax when you withdraw, and withdrawals are taxed as ordinary income.
- Inside a Roth IRA: Interest is never taxed, provided your withdrawal is qualified (you are age 59½ or older and the Roth has been open at least 5 years).
- What you owe each year: Nothing. Zero. The annual 1099-INT that taxable CD holders receive does not apply to IRA CDs.
- What triggers tax: The withdrawal (Traditional) or a non-qualified Roth distribution. The CD's interest crediting cycle is irrelevant for tax purposes.
If you are under age 59½ and withdraw, two penalties can stack: the bank's early withdrawal penalty (typically 90 to 365 days of interest) and the IRS 10% additional tax on the withdrawn amount. The bank's penalty is enforced by the bank; the IRS penalty is enforced via Form 5329 on your tax return.
IRA CD ladder vs IRA MYGA ladder
You can build the same ladder with MYGAs instead of CDs. A 5-rung IRA MYGA ladder ($50K in each of 2-year, 3-year, 4-year, 5-year, and 6-year MYGAs from various A-rated carriers) at mid-2026 rates yields a blended ~5.55% APY, vs ~4.36% for the IRA CD ladder. On a $250K starting balance over 5 years, the MYGA ladder compounds to roughly $35,000-$40,000 more inside the same tax wrapper.
The MYGA ladder has the same structural benefits as the CD ladder: a rung matures every year, you average out timing risk, RMD-friendly. Surrender charges on individual rungs are typically waived for RMD withdrawals on most A-rated carriers.
When a MYGA beats an IRA CD
An IRA MYGA (multi-year guaranteed annuity) is, in plain English, a CD-equivalent issued by an insurance carrier instead of a bank. Inside an IRA wrapper, both are tax-deferred. The tax wrapper is identical. The difference is the rate, the insurance backing, and the surrender mechanics.
| Feature | IRA CD (bank) | IRA MYGA (insurance) |
|---|---|---|
| Typical 5 years (blended ladder) rate (mid-2026) | ~4.36% | ~5.55% |
| Tax treatment inside IRA | Deferred | Deferred (identical) |
| Insurance / guaranty | FDIC $250K per depositor per bank | State guaranty fund, typically $250K-$300K per owner per carrier; backed by carrier balance sheet |
| Early access | Pay 90-365 days interest, get principal back | 10% free withdrawal annually most carriers; surrender charge on excess |
| Rate lock-in length | 3 months to 5 years typical | 3 to 10 years; 5-year is most common |
Worked example: $250,000 for 5 years:
- IRA CD at 4.36%: $309,464 at maturity
- IRA MYGA at 5.55%: $327,515 at maturity
- MYGA advantage: ~$18,051 over the 5-year period on the same starting balance
The rate gap exists because MYGA carriers hold longer-duration corporate bonds than banks hold; banks fund CDs primarily with short Treasuries. Inside an IRA, where you cannot spend the principal until 59½ without penalty anyway, locking up for the full term costs you nothing extra. The MYGA is a better fit for IRA money the same way it is for taxable money, with one added point: the tax-deferred wrapper is "redundant" inside an IRA, but that does not make the MYGA worse. It just means you are buying an insurance product purely on rate, not on tax shelter. And on rate, it usually wins.

RMD coverage from a ladder
What happens at age 73 with RMDs?
Under SECURE Act 2.0, Required Minimum Distributions (RMDs) begin at age 73 for Traditional IRA holders (and SEP/SIMPLE IRA holders). Roth IRAs have no RMD during the original owner's lifetime. For an IRA CD, the practical issue is liquidity: if your full IRA balance is locked in a single 5-year CD, you may need to break the CD to take your RMD. Two solutions:
- Ladder. Hold multiple smaller CDs maturing in different years; pull RMD from the maturing rung. See IRA CD ladder strategy.
- RMD-friendly product. Most IRA MYGAs allow penalty-free withdrawal of the RMD amount each year. Ask the carrier in writing before signing.
The ladder is the textbook RMD solution. Once you are 73+, your annual RMD is approximately 1/27 (~3.7%) of your IRA balance in the first year and rises with age. A 5-rung ladder produces a maturing rung worth ~20% of balance each year, more than enough to cover the RMD. You take the RMD from the maturing rung and reinvest the remainder.
Common ladder mistakes
- Building all rungs at one bank at the same time. If the bank's rate sheet is below market on the day you open, every rung is below market. Spread the opening dates across a week or two and shop rates.
- Not using auto-renewal flags carefully. Some banks auto-renew at posted-rate-on-maturity, which can lock you in below market if the bank's posted rates drift down. Set a calendar reminder for each maturity.
- Forgetting beneficiary designations. Each IRA needs a beneficiary on file. If you split across multiple banks/IRAs, update all of them.
- Confusing CD ladder with bond ladder. A bond ladder has interest-rate-driven price volatility; a CD ladder does not. Both have similar reinvestment-rate exposure.
