The 2015 Internal Revenue Service tax refund schedule is available on the official IRS website, at IRS.gov. Individual taxpayers can use the interactive tool to check the status of an anticipated refund by inputting the appropriate Social Security number, filing status and the amount of refund expected, explains the IRS.
Refund schedule status is available 24 hours after filing a tax return electronically or about four weeks after mailing a paper return, according to the IRS. The IRS provides the actual date on which a return should be expected; generally, refunds are processed and sent within 21 days of the return's filing date. The IRS Where's My Refund site is updated about every 24 hours.
