If you come back online, I will explain your last question to you as long as you agree to credit (rate) the previous expert as he's done all the work and I have no interest in telling you otherwise.
You are focusing on a minor point; the $75. difference is simply the fact you actually don't have the final figures so the first time he just rounded & used 30% verses 30.124%.
As you can appreciate, this is a complicated area, and the Expert that picked up your question is one of the best if not the best Expert that we have in the tax area. Most attorneys, even tax attorneys, aren't really able to get into the detail computations; that's why there are CPAs. You ran into Lev who is an exception to the rule, he's not a CPA, but he's an attorney who specializes in all types of tax matters and he also has 30 years of experience and advanced degrees; my point being he knows what he talking about.
At one point you mentioned that your tax bracket from your other income is minimal; Is that correct? Do you & your husband file a joint return and is your combined other income minimal, ie. Social Security, etc. The reason I'm asking is that it may be that any long term capital gain is not taxed at all in your tax bracket.
Right now, there are 4 interests in that home. The 3 remaindermen and your mother.
I'm just going to repeat using rounded figures. Based upon your mother's age, she owns approximately 10% of the property. Each Remainderman owns 1/3 of the remainder or 90%/3 = 30%.
So if you go back over Lev's detail computations, disregarding the error when he made a mistake that there were only 2 remaindermen, he's laid everything out for you.
I'm sure he's been working since early this morning and is probably had it at this point, so please understand, that the system requires us to spend a lot of time with no guarantee that we will be compensated. This time of the year, it becomes very busy, so when we take on a question such as yours, it means we must give up a lot of other questions that can be answered quickly for the most part. Eventually, after a long day, the frustration sometimes sets in.
Trust me, if Lev had given you bad information, there are other experts, including me who would jump in to make sure any error was corrected. There's nothing wrong with anything he told you or computed for you.
If I can help further, I'll be happy to. Just ask.
