We are a married couple with 2 kids....We made $151,971 gross in 2016...This is $71 over 25% tax bracket and bumps us into the 28% bracket. Will a $100 401k contribution bump us back down to 25% bracket and save us thousands of dollars ?

No.  The tax system is a graduated system which means the rate increases at incremental levels. First it starts with taxable income, so your "gross" amount may not be reflective of your taxable income.  Gross income reduced for any adjustments, exemptions and deductions equal the taxable income.  

  • If I used your example with the basic standard deduction and four exemptions your taxable income is $123,171.
    • $151,971 - $12,600 (standard deduction) - $16,200 (4 exemptions) = $123,171
  • Of the taxable amount in this example $47,871 is in the 25% bracket.  Until and unless your income is reduced by this amount part of the taxable income will remain in the 25% bracket.  
  • As you can see for each $100 you reduce your taxable income you keep $25.

If you use your actual figures such as itemized deductions your taxable income will be much lower than our example. The next drop in rate to 15% begins when the taxable income is below $75,300.

mammasboypowerspo, only the $71 that falls in the 28% tax bracket is being tax at 28% instead of 25%, a $2 difference.  In fact, there may even be no difference if you have reported at least $71 in long-term capital gains or qualified dividends since these are taxed at 15% whether they would otherwise be taxed at 25% or 28%.
