I modeled this out with 2016 serving as current tax code, and 2017 as Trump's proposed plan going through as written currently.

The tax due would go up about $600 if you only focused on the bracket itself. Trump's plan will eliminate the personal exemption of $4,050 in 2016, which is a bad guy and would cost you more on top of the $600 already calculated. However, Trump's plan increases the standard deduction from $6,300 to $15,000 which is a gigantic swing of a good guy in your favor. So in reality, you're calculating your tax under Trump's proposal - when you take the standard deduction and personal exemption proposals into account - you're starting at a point that's $4,650 lower based on his tax policy.
So, even with the brackets changing, it's only half the story. You will save almost $1,500 dollars under his proposed policy if you had $150,000 in earnings subject to tax. It will be harder to get to itemizing $15,000 in mortgage interest/property taxes, etc and charitable contributions unless they total over $15,000, but you're ahead already anyways. Traditional 401k contribution increases will further reduce your windfall, as it will reduce the amount of taxable dollars "exposed to the bracket." You mentioned a dependent, so if this is a child you could further your windfall with deductions for childcare costs up to the average in your state, as well as "HSA-like pre-tax contribution accounts" for child care expenses which is phenomenal, HSA's are the best deal in the tax code IMO.
The MoneyTalksBlog went into none of the above detail, which is a disservice to its readers and truly understanding the proposed tax changes, which as you see are a nice refund check for higher earners. I had a 30,000 foot understanding of all this prior to today, but liked reading the policy and hammering the math out here as I now understand the proposal better. I'm a CPA, but do corporate accounting and not individual tax as my job (do family and friends taxes for free, not complex or over my head returns) so this was a good refresher/learning on Trump's proposed tax policy. Let me know any other questions, I like diving into this stuff and I hope it helped you out and enjoy the

. Now the question is whether it goes through as drafted, time will tell on that end.
ETA: The MoneyTalksBlog technically touched on the standard deduction raise, but didn't seem like the tone of the article or the key takeaway, which when you do the math is a huge driver, much moreso than the bracket changes.
