The 2018 filing season for 2017 tax-year returns officially launched on January 27. On the other end of the filing season, taxpayers have two additional days to file their 2017 returns: the traditional April 15 filing deadline moves to April 17 this year. Some early filers, however, may find their refunds delayed if they are claiming the additional child tax credit (ACTC) and/or the earned income tax credit (EITC).
