I use Turbo Tax (neither endorsing it or railing against it), and I usually by this time have a pretty good idea of what my taxes will be. Being retired and no longer being an earner from employer or own business, my returns are rather simple. So other than waiting to see any gains/losses in taxable accounts I pretty much have it down. I always since being retired set a fixed amount I take from my social security, and pensions, and MRD withdrawals to cover federal taxes with a little buffer so I get something back (didn't want to get into situation where I owed enough at end of year to have to start filing quarterly taxes which used to be a pain). 

My end of year looks remarkably rather unchanged (only slight increase in refund), but still waiting for taxable account results which will likely only bring it down further. IF so, the Trump "tax cut" for me has been pretty much not much of anything. 

Wondering how it looks for the rest of you. 

I have seen some wild claims of what others think they are going to get back extra on other political blogs and either they are ignorant, lying, or have some strange circumstance that is rewarding them greatly. 

Meanwhile business (my last years I was a business owner) have benefited greatly from Trump's plan. Too bad I am still not in that arena. The sad thing is that the cuts have increased our Nation Deficit by another $1 Trillion which we and our kids will have to figure out how to pay back. And the other sad this is that business in general was doing well without the cuts.
