What's the advantage of direct deposit vs. a check?
Speed, security, and convenience. By e-filing and choosing direct deposit, the IRS expects to issue 9 out of 10 refunds within 21 days, as opposed to 4-6 weeks for a check in the mail.
With a direct-deposited refund, you don't need to worry about your check getting lost in the mail, nor do have to go to the bank to deposit or cash it.
You can even split a direct-deposited refund into 2 or 3 different accounts unless you're using the Pay With My Refund option to pay your TurboTax fees.
To help combat fraud, IRS regulations prohibit direct-deposits into foreign accounts – only domestic accounts located in the United States.
Also, the IRS won't deposit more than 3 refunds into the same bank account during the same year. Additional direct deposit requests will instead be mailed out as refund checks to the taxpayer's address on file.
