Here is an interesting way to see how your taxes are impacted from 2017 to 2018. It isn't fully 100% accurate due to things such as if the new tax law didn't take effect, the IRS adjusts the tax tables every year and some tax code provisions expire and change based on various legislation from the past.
But take your 2018 financial information and if you have tax software or a Coop to do it for you, put in your data into 2017 software. Check out what it spits out. Compare to your 2018 tax results. Again, not 100% accurate to the tax legislation but I'm guessing it is 95% relevant
