What form do you need to fill out I have no w-2 form did not work.?

If you do not have a W-2 form, you can use Form 4852, which serves as a substitute for the W-2. You will need to provide information about your income and withholding based on your pay stubs or other records. Additionally, you may want to contact your employer to request a copy of your W-2 or to obtain the necessary information to complete Form 4852 accurately.
