UPDATE: Tax Plan Square Off: Romney vs. Santorum vs. Gingrich

After we published our blog on the Romney vs. Santorum tax plans, we were inundated with requests to add the Gingrich tax plan to the analysis.  So, below is an updated chart that includes the results of the Gingrich tax plan.  Our methodology remained the same, using the hypothetical taxpayers and the typical income and deductions.

The following are the hypothetical taxpayers and the typical income and deductions:

The following are the results:

Some notes about this Update (these are in addition to the notes in the Romney vs. Santorum blog):

• The Gingrich tax plan gives taxpayers a choice between paying taxes under the current tax system or paying tax at the single 15% tax rate.  The amounts on the chart above are the lesser of the Gingrich plan or the current tax system.
• The Gingrich 15% tax rate would allow some deductions and would not include Capital Gain, Interest or Dividend Income.  The deductions allowed would be Mortgage Interest, Charitable Contributions and a $12,000 personal exemption for each individual and dependent.
• Gingrich would retain the expanded Earned Income and Child Tax credits.  We assumed these would be retained at the 2012 levels.
• We assumed that Social Security income would be taxed at 100% under the Gingrich 15% plan.

Now some analysis (this is in addition to the analysis in the Romney vs. Santorum blog):

• The biggest, most obvious difference between the Gingrich plan and all the other plans, is the amount of taxes high-earners will pay under the Gingrich plan.  In our example, none of the Capital Gain, Interest and Dividend income will be taxed and the salary ($1,250,000) is only taxed at 15% for the Executive.  It results in about a 50% reduction or $160,000 less in taxes than the Santorum plan.  Even if we assumed that Capital Gain, Interest and Dividend income would be taxed under the Gingrich plan, it would still result in a 35% reduction or $120,000 less in taxes than the Santorum plan.
• Both Santorum’s and Gingrich’s plan would result in substantial savings for the Family, also.  The Gingrich plan would give a $12,000 personal exemption for each individual and dependent.  The results for families with one or fewer children would be very different, though (our example assumes three children).  For example, assuming the same income and deductions for the Family, but having only one child, would actually result in higher taxes under the Gingrich alternative method (but according to his plan, you would be able to select the lower tax calculated under the current tax system).

Prior to publishing this blog, we sent it to the Gingrich campaign for their comments, but did not hear back from them.
