 If the status in Where’s My Refund? shows “Refund Sent”, the IRS has sent your tax refund to your financial institution for direct deposit. It can take 1 to 5 days for your financial institution to deposit funds into your account. If you requested that your tax refund be mailed, it could take several weeks for your check to arrive.
