No, if you are filing a joint return with your spouse, your refund does not have to be deposited into a jointly-held account. According to the IRS guidelines, you can request the IRS to direct deposit the refund into your account, your spouse's account, or a joint account. However, it is important to verify with your financial institution whether they accept a joint refund into an individual account, as state and financial institution rules can vary. The IRS can only deposit refunds electronically into accounts that are in your own name, your spouse's name, or a joint account.
