I worked on testing the Individual Tax System at the IRS for Y2K problems. We had to use actual tax returns for our testing. We had access to your tax returns. We got in trouble if we deliberately accessed someone whom we knew, but that was all. The fact that I had TS SI/TK clearance at the time made no difference. All one had to do is pass a National Agency Check to gain access. A couple of my co-workers were actually delinquent on their taxes.
ALOT of politicians are delinquent
