The IRS issues most refunds in less than 21 days, although some require additional time. You should only call if it has been: 21 days or more since you e-filed; 6 weeks or more since you mailed your return, or when Where's My Refund tells you to contact the IRS; Taxpayers who claim the Earned Income Tax Credit or the Additional Child Tax Credit may experience a refund hold. According to the Protecting Americans from Tax Hikes (PATH) Act, the IRS cannot issue these refunds before mid-February.
