The IRS has announced that the 2019 filing season will begin on Jan. 28, 2019, for individual taxpayers. The IRS began accepting business tax returns (non-1040 series) on Jan. 8. Taxpayers should keep several things in mind during this challenging period:

• File electronically. The IRS will accept paper and electronic tax returns, but taxpayers are urged to file electronically to speed processing and refunds.
 
• Tax refunds. Refunds will be paid, but the IRS cautions that returns will continue to be subject to refund fraud, identity theft and other internal reviews as in prior years. Taxpayers should use e-file or Free File with direct deposit to help speed refunds.
 
• Tax filing. Taxpayers can go ahead and start working on their returns in advance of the Jan. 28 opening. Both tax software and tax professionals will be available and working in advance of IRS systems opening. Software companies and tax professionals will then submit the returns when the IRS systems open. The IRS strongly encourages people to file their tax returns electronically to minimize errors and for faster refunds.

Additional information related to the 2019 filing season will be available in coming days on www.IRS.gov.
