Although the IRS will begin accepting both electronic and paper tax returns Jan. 29, paper returns will begin processing later in mid-February as system updates continue. The IRS strongly encourages people to file their tax returns electronically for faster refunds. The IRS set the Jan. 29 opening date to ensure the security and readiness of key tax processing systems in advance of the opening and to assess the potential impact of tax legislation on 2017 tax returns.
Note: The IRS will start processing most returns on January 24, but will not start processing returns with the Earned Income Tax Credit (EITC) or Additional Child Tax Credit (ACTC) until Feb. 15, 2017. The IRS will begin processing tax returns on January 24, 2017, for taxes paid/owed in 2016. In general, the IRS says that returns with refunds are processed and payments issued within 21 days. For paper filers, this can take much longer, however. The IRS and tax professionals strongly encourage electronic filing.
