Do I need to wait for the W2 for a job I had for 3 weeks or can I file without it?

[Texas Roger]

Yes you must wait for it. All income from all sources must be entered on your tax return. The IRS will get the W-2 and then your return will not match the information the IRS has if you file without the W-2.

Every 2022 W-2 that you received must be reported on your 2022 tax return, even if they are for small amounts.  Remember that each one of those W-2’s has your Social Security number on it, and that income was reported to the IRS by the employer.  You do not want to get in trouble with the IRS for under-reporting your income.

ALL of your W-2’s must be entered on the SAME tax return.  

Go to Federal>Wages & Income to enter a W-2.

After you enter the first one, you click Add Another W-2.
