You can direct your refund to any of your checking or savings accounts with a U.S. financial institution as long as your financial institution accepts direct deposits for that type of account and you provide valid routing and account numbers. Examples of savings accounts include: passbook savings, individual development accounts (IDAs), individual retirement arrangements (IRAs), health savings accounts (HSAs), Archer MSAs, and Coverdell education savings accounts.

However, some financial institutions will accept direct deposits for some types of accounts, but not others. Contact your financial institution to ensure they will accept your direct deposit and verify your account and routing number.

IRS also encourages taxpayers and their preparers to ensure account and routing numbers are accurately entered on returns so your funds can be deposited as intended.
