The IRS issues most refunds in about 21 days, although some returns take more time to review.
For the most up to date information on your refund, you can track your federal refund here: Where's My Refund? which provides your current status and a specific, personalized date for your tax refund once it is available. You may also download the IRS2Go app to check your Federal refund status.
Here is the general timeline of e-filed returns:
Transmission > Acceptance > Processing > Approval > Refund.
