If he can't/won't talk to you and answer your questions, dumb as they may seem, find another tax guy. It is their job to educate you on the things you need to know when you ask who what when where and how. That is why they have a "degree" in tax matters, and you do not.
Case in point. I am over 65 now getting medicare. Have a supplement policy. Went to the ins lady from my job, when I was transitioning to medicare and asked her opinion. I was losing my full time status so it all happened at a good time. I had been to no less than 3 seminars on medicare and the different plans, what "seniors are supposed to know" and was more confused than ever. She spent time with me, explained it all as well as can be, said that yes, they made it more complicated all the time.
After several scenarios, asked her point blank what her husband had because he had retired the year before and had had a knee replacement. What it paid, did and didn't cover.... She told me and I said, okay I want that because I am going to have an ankle and a knee replaced in the next couple of years.
This fall I kept hearing other ads about the new medicare advantage plans, all the little perks they cover and all. So I called her up and said, okay, I've been hearing all this stuff, what's the deal. Had a friend that switched over and all the little things she would be getting out of it at a lesser cost. She explained the differences, and that the lower cost plan, did offer up some "everyday" perks, that if anything about my health would change, and I needed more medical care, that down the road I would not be able to pass underwriting to get a supplemental policy like I have now.
I said, thank you. You are the expert, I just wanted someone who knew what the little inside things were to explain it to me. I said, It all sounds so good in the ads, but I figured there were things that weren't being said. If you think this is where I should be, then that's fine, that's what I will do.
So, when you go to an "expert", like a tax person, they don't have to go into minute detail, but you are paying them to look out for YOUR best interest. And they should explain what you need to know enough to get you in the right direction, the right position for what you are doing.
