Are you a W-2 employee? Or are you self-employed---working as an independent contractor? If you are a W-2 employee, you will receive a W-2 by the end of January. If you are an independent contractor you need to be keeping meticulous records for yourself of your business expenses such as mileage, supplies, tools, etc. You may or may not receive a 1099NEC from your client(s) if you are self-employed, so you need to keep records for yourself of the income you receive. Most tax documents are issued in late January/early February, so you will need to make sure that anyone who needs to send a tax document to you has your address.
