As the tax plan has not yet been finalized, I'm not sure what the use of this calculator is. You don't really know what your new taxes will be yet. I would wait until it is reconciled and signed to worry about that. YMMV. If you want to influence the outcome of what is in the tax bill, then finding the thing in it that you don't like the most (and preferably it is in only in one of the bills) and advocating for that to be removed or changed is probably the most useful. Academia was up in arms about losing its special tax break on tuitions (only in House bill), got a bunch of press, and it looks like that might be left out in reconciliation.
