Despite the partial government shutdown, the IRS plans to accept returns and provide refunds to taxpayers as scheduled.
Typically, employers must file and postmark tax-related documents by January 31. Therefore, you should receive your forms by early February. But if you receive all your forms before then, you can file your tax return as early as January 28.
The deadline for filing your 2018 tax returns is Monday, April 15, 2019.
