You must list only the work performed in the past 15 (fifteen) years, unless you have a date-last-insured. If you have a date-last-insured, you must list the jobs performed in the 15 year period prior to the date-last-insured. If you don’t know if you have a date-last-insured, call you caseworkers who will tell you what that date is. If you don’t remember the dates of your employment just say “approximately” and put the dates down, e.g., from approximately 2015-2018. Then name the employer and the location of employment, for example, Walmart in Cape Coral, Fl. And, in the column described “Duties Performed”, list only the significant duties, for example, Cashier and Janitor, or Secretary and Bookkeeper and Filing Clerk. If you have more than one or more significant duties make sure you list all of them. If you have any questions, call your case manager. You should look at your detailed earnings record which is in your Social Security file to refresh your memory about when and where you worked. Your case manager can give this to you if you ask for it. This detailed earnings record only lists the places of employment where you were paid actual wages. If you were paid cash, you must report it to the IRS and pay your taxes. It is illegal not to pay taxes on work you performed for cash.
