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. The IRS expects the first EITC/ACTC related refunds to be available in taxpayer bank accounts or on debit cards by the first week of March, if they chose direct deposit and there are no other issues with their tax return.
