Find the status of a tax refund by using the Where's My Refund? tool on the IRS website. Information for e-filed returns is available on the tool 72 hours after the refund is accepted by the IRS, and information for mailed returns is typically available three to four weeks after mailing the return, according to the IRS.
To use the tool, go to the IRS website, click the Refunds tab, and select "Where's My Refund?" on the next page. Fill in the Social Security number of the main filer, the filing status listed on the return, and the exact amount of the refund. According to the IRS, knowing the exact refund amount is important to help find the refund information.
