What do you need to access information from Where's My Refund?

The information needed to access information from the Where's My Refund tool is the taxpayer's Social Security number, the filing status of the taxpayer and the amount of the anticipated refund, explains the Internal Revenue Service. The Where's My Refund tool is updated once every 24 hours.

Taxpayers can start checking the Where's My Refund portal 24 hours after the IRS receives their income tax return when filed electronically, explains the IRS. If the taxpayer filed his return by mail, the information should become available on the Where's My Refund portal about four weeks after the paper tax return is mailed.
