You cannot change the bank account for your direct deposit after you file your tax return. Your spouse should talk to her bank----the bank might refuse the direct deposit to an account with only her name on it if the deposit has both of your names on it. If that happens, the refund will be sent back to the IRS and then the IRS will issue a paper check and mail it to the address on the tax return.
