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.
The IRS will begin accepting and processing tax returns once the filing season begins, as we do every year. That will not change. The IRS still expects to issue most refunds in less than 21 days, though IRS will hold refunds for EITC and ACTC-related tax returns filed early in 2017 until Feb. 15 and then begin issuing them. This is one more step the IRS is taking to ensure taxpayers receive the refund they are owed.
