The Impact of the Presidential Candidates’ Tax Proposals on Effective Marginal Tax Rates
A taxpayer’s effective marginal tax rate (EMTR) is the percentage of an additional dollar of income that would be paid in federal income tax. An individual’s EMTR could affect the decision to work or save more, or avoid income tax. We use the TPC’s microsimulation model of the federal tax system to calculate EMTRs under current law and under the presidential candidates’ proposals. The Obama plan would lower EMTRs for the majority of households in 2009. Close to 80 percent of the population would see no change in their EMTR under Senator McCain’s plan; most others would face lower rates.
The Presidential Candidates’ New Tax Proposals - October 27, 2008
In response to the deterioration of the economy and the decline in asset values, Senators McCain and Obama have offered new proposals related to unemployment compensation, retirement savings, taxation of capital gains, and job creation. Although the proposals would provide some benefit, they have significant shortcomings.
Refundable Health Insurance Tax Credits
In a previous post, Len Burman reported that a substantial portion of Senator Obama’s non-health tax proposals would be provided as net refunds, over and above income tax liability. This is a key difference from Senator McCain, whose proposals would mostly benefit taxpayers (and mostly those with high incomes).
Joe the Plumber, Obama’s Tax Proposals, and Small Businesses
Poor Joe the Plumber has become a political metaphor: something no one ever wants to be. As we all know by now, based on his actual (rather than aspirational) income of $40,000, Joe would get a slightly bigger tax cut under President Obama than President McCain.
But in one sense, even though the real Joe doesn’t own a business, most small business owners, like Joe, also have very modest incomes. Based on a sample of individual income tax returns, TPC finds that among tax units that receive most of their income from their own business, a partnership or a farm (reported on schedules C, E, or F), more than half have income below $30,000 and 80 percent make less than $100,000. (Table T07-0206)
Senator McCain’s Universal Health Insurance Proposal?
When TPC analyzed Senator McCain’s proposal to replace the income tax exclusion for employer-sponsored health insurance with flat refundable tax credits of $2,500 for single coverage and $5,000 for family coverage, we found only modest net effects on coverage. Our model predicted that more than 21 million people would gain insurance coverage in the individual nongroup market by 2013 while 16 million would lose employer-based coverage. Despite a $1.3 trillion price tag over the next decade, the proposal would yield only modest and temporary gains.
