I would caution anyone looking to use John for their tax-filing purposes. All seemed to be good and well, until it wasn't.I used John's services for two years. The first year was pretty standard. The second year we had a few issues with a non-Illinois state tax return, where an issue was overlooked and we later were contacted by that state that we had unpaid taxes. This is a scary situation, no doubt, but it was eventually resolved - not quickly, but he showed a little urgency. My major disappointment was when I was corresponding with John to file taxes this year, and he suddenly decided to deny services to me.I was taken aback, as it was out of nowhere, and I am still unaware as to what it is that bothered John about me. I inquired, but he did not respond. I find this to be somewhat troubling. Perhaps his reasoning was something he was not proud to say, or perhaps he did not feel it was worth spending the time to explain. Either way, it was a bit frustrating on my end, because while last year had been less than ideal, I was still pleased enough to keep using John's services, and had been depending on him. To suddenly have my tax filing plan spun into disarray was unprofessional. To offer no reasoning as to why he did this was inconsiderate.
