Best 9-Month CD Rates (May 2026)

The 9-month term is the right choice for money with a roughly three-quarter horizon. Common scenarios: a tax bill due next April that you want to start earning interest on now, an education expense due at the start of the next school year, a wedding or major purchase planned for early 2027, or the third-rung position in a quarterly CD ladder. The 9-month window covers the gap between the well-shopped 6-month and 12-month products.

The 9-month tier also makes sense when you want to participate in a slightly longer rate lock without committing to a full year. In the current inverted-curve environment the 9-month rate at 4.25% is barely below the 6-month rate at 4.30% and slightly above the 1-year rate at 4.20%. You get an extra three months of locked yield versus the 6-month at almost no rate cost. That makes the 9-month a quietly attractive choice for savers who want defensive positioning without a full year commitment.

The case against the 9-month is the thin field. With only roughly six to eight banks publishing standalone 9-month rates, the competitive pressure that drives short-term and standard-term rates higher is muted. The 9-month rates rarely lead the entire CD market the way 6-month rates do. If maximizing APY matters more than the specific term length, the 6-month CD at 4.30% remains a better deal.

The 9-month CD at 4.25% sits five basis points below the 6-month CD at 4.30% and five basis points above the 1-year CD at 4.20%. That is a tight cluster reflecting the inverted yield curve at the short end of the CD market in May 2026. The 18-month tier at 4.05% is twenty basis points below the 9-month, and the 24-month tier at 3.90% is a further fifteen basis points down. The penalty for committing longer is real and consistent.

The decision tree for a saver choosing between 6, 9, and 12 month CDs is straightforward. If your money is unrestricted and you want the highest APY, choose the 6-month CD at 4.30%. If your money has a roughly 9 month horizon and you want to avoid the reinvestment decision at the 6 month mark, choose the 9-month CD at 4.25%. If you want maximum rate lock protection against expected Fed cuts in the next year, choose the 12-month CD at 4.20% even though it pays slightly less per year. The yield differences are tiny relative to the structural fit of the term to your need.

The Federal Reserve H.15 release at federalreserve.gov/releases/h15 is the underlying benchmark; Treasury yields drive CD pricing with a lag. The 9-month Treasury (which is roughly the 26-week T-Bill) yields about 4.00% as of mid-May 2026, so the top 9-month CD rate at 4.25% carries a healthy 25 basis point premium. That premium is wider than the FDIC National Rate Cap for the 9-month tier, which typically sits around 1.40% for less-than-well-capitalized banks.

CD interest is taxed as ordinary income in the year it is paid or credited to your account. A 9-month CD opened in May 2026 matures in February 2027, so the full interest amount counts as 2027 ordinary income on your federal 1040. The 1099-INT arrives from your bank by the end of January 2028. State income tax also applies in 41 of 50 states, with the no-tax states being Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming (New Hampshire has no wage tax but did tax interest until the 2027 sunset; that distinction matters for current returns).

For a 9-month CD that straddles two calendar years (opened in October 2026, mature in July 2027 for example), all interest is credited at maturity and counts in the year of maturity. No phantom income accrual applies because the term is under one year. That is a clean reporting profile compared to multi-year CDs that compound internally and trigger annual tax even without cash being received. The IRS Pub 550 reference at irs.gov/forms-pubs/about-publication-550 covers the full mechanics. See our CD interest taxation page for the state-by-state breakdown.
