You can file the 2020 federal tax return after you have received every Form W-2 and Form 1099 that you are required to file on your personal tax return, Form 1040. All W-2's and Form 1099's are entered on only one tax return.
Filing for tax year 2020 cannot begin until after January 1, 2021.
The IRS will not be accepting any type of 2020 tax return until late January 2021.
Employers are required to provide the W-2's no later than January 31, 2021.
Financial institutions send Form 1099's in January and February.
Filing a tax return before mid-February is not advisable due to the IRS having to provide new forms and schedules for tax year 2020.
