If you worked as a W-2 employee then you need your W-2 for your tax return. ALL of your 2024 income needs to be entered on the same tax return form. So you will need to double up on your efforts to obtain your W-2 in order to prepare an accurate tax return.
W-2’s come from employers. There is not a federal or national website that provides W-2’s.
Some employers have payroll sites that will have your W-2. You might need to phone, drop in, email and/or snail mail an old employer to make sure they know where to send your W-2.
You can get a wage and income transcript from the IRS: It will not show the actual W-2, 1099’s, etc, but will show the income information the IRS received. It will not, however, show your state information. It will only show the federal information.
