A CD ladder vs Treasury bond ladder both stagger maturities to provide regular liquidity and reinvestment opportunities — but tax treatment differs sharply. Treasury interest is exempt from state and local income tax under 31 USC §3124; CD interest is fully taxable at all levels. In high-tax states like CA (13.3%) or NYC (~14% combined), Treasury ladders often win on after-tax yield even when the headline rate is lower.
How CD Laddering Works
You split your investment into equal portions and buy CDs with staggered maturities — typically 1, 2, 3, 4, 5 years. As each CD matures, you reinvest the proceeds in a new 5-year (or longest-term) CD. Pros: FDIC insurance up to $250K per bank per depositor, slightly higher yields than Treasuries in most periods, no interest-rate-risk if held to maturity. Cons: state-taxable interest, early withdrawal penalties (typically 6-12 months of interest), less liquid than Treasuries.
How Treasury Bond Laddering Works
You buy a series of Treasury notes or bills with staggered maturities at TreasuryDirect or through a brokerage. Pros: full faith and credit of the US government (no $250K cap), state-tax-exempt interest (31 USC §3124), highly liquid secondary market. Cons: slightly lower headline yield than CDs in some environments, requires basic familiarity with Treasury auction or brokerage purchase, no early withdrawal penalty but selling before maturity means market-rate risk.
The State Tax Math That Often Wins
Example: $100,000 ladder in California (9.3% state) with federal 24%. CD at 4.45% pre-tax = 4.45% × (1 - 0.24 - 0.093) = 2.97% after-tax. Treasury at 4.20% pre-tax = 4.20% × (1 - 0.24) = 3.19% after-tax. Treasury wins by 22 basis points despite a 25 bp lower headline. In NYC with 13%+ combined state/city, the Treasury advantage widens to 40+ bp. In tax-free states (FL, TX, WA, NV, SD, TN, WY, NH for wages), CDs typically win on headline rate.
Which Should You Choose
(1) High-tax state + taxable account → Treasury ladder. (2) Tax-free state + taxable account → CD ladder (slight headline advantage). (3) IRA / 401(k) (tax-deferred) → CD ladder or whichever has the higher pre-tax yield (state tax exemption doesn't help in tax-advantaged accounts). (4) Over $250K → Treasury ladder (no FDIC cap concern). (5) Need maximum liquidity → Treasury ladder (secondary market is deep). Many investors use a hybrid approach: short rungs (1-2y) in CDs for slight yield pickup, longer rungs (3-7y) in Treasuries for state tax exemption.
