Best Internet Banks, 2018

BEST: Ally Bank

Ally Bank, our top pick among online-only institutions, began nearly a century ago as GMAC, the auto-financing arm of General Motors. Ally keeps its account offerings simple: There's only one checking, savings and money market account, and each has no monthly fees and strong yields. Ally offers a range of CDs that can be opened with any amount, including an 11-month No-Penalty CD that allows you to withdraw your money, including interest, at any time without paying a penalty. (Yields range from 1.25% to 1.8%, depending on initial deposit.) The High-Yield CD pays between 2.1% and 2.3% for a one-year term, depending on initial deposit.

To address jitters about branchless banking, Ally gives you free checks, postage-paid deposit envelopes and free incoming wire transfers. You can avoid ATM fees by sticking with the more than 43,000 machines in the Allpoint network in the U.S., but Ally will offset up to $10 per month in charges from other banks' ATMs.

Ally also supplies a suite of digital banking tools, including remote check deposit, Ally Assist (a voice-enabled help service in the iOS app) and Ally Skill (account management by voice using Amazon Alexa). Live customer service is available by phone or online chat 24-7 (phone wait times are posted on the website), or you can correspond via Facebook Messenger or Ally's dedicated customer service Twitter feed. The bank offers mortgages and auto loans, as well as the Ally Invest brokerage.

RUNNER-UP: Axos Bank

With five checking accounts on tap, banking at Axos Bank (formerly Bank of Internet USA) can be as simple or complex as you want. On the simple end, we like the no-frills Essential Checking, which doesn’t charge for overdrafts and reimburses all domestic ATM fees. On the more complex end, Rewards Checking dangles a rate of 1.25% as long as you meet several conditions each month (including a direct deposit of at least $1,000 and frequent use of the debit card). You need $100 to open a checking account.

Savings choices are more straightforward. The lone savings account yields a respectable 1.3%; the money market account earns 1.05% and includes a debit card. As with checking, there are no ongoing fees or balance requirements beyond an initial $100 deposit. You’ll need $1,000 to open a CD; a five-year term recently yielded 2.25%.

Only the CashBack Checking and Golden Checking (for those 55 and older) charge the $25 overdraft fee; the other four checking accounts will reject the overdrawn item, at no cost to you. Axos Bank doesn’t partner with any ATM networks, but it will reimburse up to $8 monthly in ATM fees in the U.S. for the Golden checking account, up to $12 for the teen-oriented First Checking, and unlimited amounts for the other accounts. There is only one physical branch, at company headquarters in San Diego, but otherwise live help is available anytime by phone or from 7 a.m. to 6 p.m. Pacific time via online chat.
