Have a job offer contingent on clearance.
Worked a second weekend job as a bartender concurrent with other full time employment until 2007. Stayed friends with the owner and helped out a few times a year from 2007 to 2011 when she was short staffed. Sometimes took no money, at most got a few hundred in cash in a year but have no records or memory of the exact amounts. In general I didn't want a job and did it as rarely as possible without leaving a friend in a bad spot. In 2012 another bartender broke his wrist and owner asked me to work weekends for about 1.5 months. I agreed but had her put me on the payroll and I declared the income and reported the employment on my OGE 450.
Fast forward to today and my sf86 and the question about failing to pay taxes. I never got a w-2 from the random times I helped out and didn't declare any income. Another friend - who has a clearance - says I'm over analyzing the situation and should not worry about this. I wonder if I should say I had some small amounts of undeclared income and try to explain it. If I do that what are the chances I will not get my clearance?
