CD FAQs — Washington
How is CD interest taxed in Washington?
CD interest is taxed as ordinary income in Washington. Washington State has no income tax on CD interest. Note: Washington has a 7% capital gains tax on long-term gains over $262,000, but this does not apply to CD interest income.

What is the best CD rate in Washington right now?
CD rates in Washington follow national market rates since they are set by banks and credit unions, not state governments. As of 2026, competitive CD rates range from 4.0% to 5.5% APY. Online banks typically offer higher rates than local branches. Check Washington-based credit unions for competitive local rates. The FDIC rate tracker and Bankrate provide current top CD rates available to Washington residents.
Are CDs FDIC-insured in Washington?
Yes — CDs at any FDIC-member bank are federally insured up to $250,000 per depositor, per institution, per ownership category. This applies equally to all Washington residents regardless of state laws. Credit union CDs are insured by the NCUA up to the same $250,000 limit. Washington residents can open CDs at any FDIC or NCUA-insured institution nationwide — in person or online.
Should I put my savings in a CD or a high-yield savings account in Washington?
The choice depends on your liquidity needs and rate expectations. CDs offer a guaranteed, locked-in rate — ideal if you won't need the money for a set period and want certainty. High-yield savings accounts are more flexible (no penalty for withdrawal) but rates can change. In Washington with no state income tax, both CDs and savings accounts benefit from the same state tax advantage — only federal taxes apply.
What is the early withdrawal penalty for CDs in Washington?
Early withdrawal penalties are set by individual banks, not by Washington state law. Common penalties: 3 months of interest for CDs under 1 year, 6 months of interest for 1–2 year CDs, and 12 months of interest for 3–5 year CDs. Some banks offer no-penalty CDs at slightly lower rates. Before opening a CD as a Washington resident, understand the penalty terms in case you need the funds before maturity.
