I got paid "under the table" for a job (paid employment, non-medical) for several months. This was a during-college job, and I had the job for several years.
Option A: List the genuine start and end dates, including the time I was paid "under the table". I was actually working at this time and I can provide documentation. Downside: The employer (and contact person) might either get in trouble for having paid me under the table or deny it to avoid getting in trouble. He may also look at the payroll system and honestly forget the time I was paid under the table, but that is less likely because, in fact, they do this a lot.
Option B: List the nominal start and end dates. Downside: It is not honest. Also, it makes it look like I wasn't doing much for several months, when if fact I was working 20+ hours/week for pay.
Which option? I am leaning toward Option A.
Edit to add: I paid taxes on my income as self-employment income (so I paid extra taxes), so I have zero liability. I actually asked an accountant, I did not break the law and I overpaid my taxes (better than not having a job). The employer actually does face some tax liability and possibly employment law violations (because I would deserve Unemployment Insurance but was not listed for it, etc.), but I suspect the statute of limitations has run out.
Another edit: I am honestly not sure the date when I switched, which pushes me further toward Option A. I might guess at the switch date but expose the situation anyway, accidentally.
