Yes, you can still file taxes without a W-2 or 1099.
Usually, if you work and want to file a tax return, you need Form W-2 or Form 1099, provided by your employer. If you did not receive these forms or misplaced them, you can ask your employer for a copy of these documents.
If you cannot get a copy of your W-2 or 1099, you can still file taxes by filling out Form 4852, “Substitute for Form W-2, Wage and Tax Statement.” This form requests information about your wages and taxes that were withheld. It may be helpful to have documentation, such as a final pay stub, available to complete it. If you do not have a final pay stub, you may still be able to complete the form by estimating your earnings. Check to see if your local VITA site can assist with this process.
