By law, the IRS must hold 2016 Earned Income Tax Credit or the Additional Child Tax Credit refunds until Feb. 15, 2017. These refunds will likely not start arriving in bank accounts or on debit cards until the week of Feb. 27 – if there are no processing issues with the tax return and the taxpayer chose direct deposit.
