Over the past few years, I have worked for myself on various information technology contracting jobs. During these three years, I believe that I made approximately $2100 total. At the time, I was over 18 and in college. I asked my dad if I needed to report this income and he said no as I was under the minimum income requirement to file. However, while doing some research on the SF-86, I found this probably counts as self-employed and if you're self-employed you have to file taxes to pay for Social Security and Medicare.
This was an honest mistake, will it affect my ability to obtain a TS clearance?
