The IRS announced that the 2017 tax filing season will begin on Monday, 1/29/18, which means that electronic and paper returns will be accepted beginning on that day. The IRS will begin processing paper returns in mid-February as its systems continue to update. Also, the IRS expects refunds on returns claiming the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit (ACTC) to be available starting on 2/27/18 (if direct deposit is chosen and there are no other issues with the return).
Tax returns are due on April 17 because of a weekend and the Emancipation Day holiday.
