FROM THE IRS WHERE’S MY REFUND SITE:

How it works

Where's My Refund shows your refund status:

• Return Received – We received your return and are processing it.
• Refund Approved – We approved your refund and are preparing to issue it by the date shown.
• Refund Sent – We sent the refund to your bank or to you in the mail. It may take 5 days for it to show in your bank account or several weeks for your check to arrive in the mail.

If you got a paper check instead of direct deposit, it’s because:

• The account is not under your name, your spouse's name or a joint account
• Your financial institution rejected a direct deposit
• You requested more than 3 electronic refunds into 1 account
