Best Banks in Idaho
Top regional banks serving Idaho include:
- D.L. Evans Bank (Burley
- ID — est. 1904
- 32 branches)
- Zions Bank (25 branches across Idaho)
- WaFd Bank (Washington Federal — 22 branches)
The largest bank by presence in Idaho is U.S. Bank (largest branch network with 50 offices and approximately $3B in Idaho deposits per FDIC data).
Best for checking: Idaho Central Credit Union (ICCU) — free checking with no monthly fees, free credit score monitoring, and a $150 new-account bonus
Best for savings: Ally Bank or SoFi — top online high-yield savings available to Idaho residents (Ally ~3.20% APY, SoFi 3.10% APY standard; niche banks up to 4.10% APY)
Regional banks often combine local branch access with competitive accounts, which is why they tend to score well with Idaho customers. Top high-yield savings accounts available to Idaho residents pay around 3.80% to 4.10% (mainstream high-yield online savings as of June 2026; niche accounts up to 5.00% with conditions) in June 2026.
National Banks Available in Idaho
If you want a big branch and ATM network, the major national banks all operate in Idaho:
- U.S. Bank (50 branches — largest branch network in Idaho)
- Wells Fargo (46 branches)
- KeyBank (21 branches)
- Chase
National banks are convenient but rarely pay the best savings rates — pair one with a high-yield online account for the best of both.
Best Credit Unions in Idaho
Well-regarded Idaho credit unions include:
- Idaho Central Credit Union (ICCU — largest in state
- $14.7B+ assets
- 64 locations
- 775K+ members)

Credit unions are member-owned and often beat banks on fees and savings rates, though membership may require living, working, or worshiping in a specific area.

Evans Bank (est. 1904, Burley) is the iconic homegrown community bank with 32 branches across southern and western Idaho. Zions Bank (Utah-based but deeply rooted in Idaho with 25 branches) is another major regional player. The state has 27 credit unions with combined assets over $21B and 64 FDIC-insured banks.

Checking, Savings, and CDs Explained
Most Idaho banks offer the same core accounts:
- Checking — for everyday spending and direct deposit. Look for no monthly fee.
- Savings — for your emergency fund. Online banks pay the highest rates.
- Money market — a savings account with limited check-writing.
- CDs — lock money for a set term in exchange for a higher fixed rate.
A common setup for Idaho residents is a no-fee checking account at a local bank plus a high-yield savings account at an online bank.
How Bank Sign-Up Bonuses Work in Idaho
Banks pay cash bonuses — often $100 to $400 — to win new customers. To earn one you typically open a new checking or savings account, then meet a requirement such as receiving a set amount of direct deposit or keeping a minimum balance for a few months. The bonus is usually paid within 90 days. As long as you would open the account anyway, it is essentially free money. We track current offers open to Idaho residents on our listings page.
