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 began accepting electronic tax returns Jan. 23, with more than 153 million individual tax returns expected to be filed in 2017. Four out of five tax returns will be prepared electronically using tax return preparation software. Many software companies and tax professionals accepted tax returns before Jan. 23 and then will submit the returns now that the IRS system is open. The IRS will begin processing paper tax returns at the same time. Employers had to have W-2 forms in the mail by Jan. 31. If you don't have your forms by that date or soon after, or if your forms aren't correct, contact the IRS, but not until after Feb. 14, according to Forbes.
