Expect an increase in your taxes if Ben Carson becomes president, because unlike almost any other contender in the Republican presidential race, his tax plan would result in a net rise in taxes for most Americans.

The retired neurosurgeon has long touted his Bible-inspired flat tax plan on the campaign trail, the details of which were revealed this week. His camp has outlined an overhaul of the federal income tax code in a proposal that includes a modified 14.9% flat tax rate and the elimination of deductions, shelters and loopholes.

For top earners and corporations, the plan would go a long way in reducing taxes. But for the rest of us, not so much.

"He's the only [candidate] who has succeeded in raising taxes on half the population," said Bob McIntyre, the director of Citizens for Tax Justice (CTJ) a Washington, D.C.-based tax policy think tank.

CTJ estimates Carson's flat tax plan would cost $9.6 trillion over 10 years and would actually translate to a 30.2% rate for most Americans when accounting for the 15.3% payroll tax rate. Its analysis indicates the bottom 20% of tax payers would experience an annual tax increase of $792 and the next 20% would see an increase of $447. The top 1%, on the other hand, it holds would get a tax cut of $348,434.

A separate analysis from The Tax Foundation concludes that Carson's tax plan wouldn't be as costly. However, it also finds that number of Americans to see a tax increase under the overhaul would be even higher.

The non-partisan think tank headquartered in Washington, D.C. estimates that the proposal would increase taxes on all income groups except the top 10%. The lowest earners would see their after-tax income fall by as much as 14.8%, and middle-income Americans would take a similar hit. The top 10% of earners, on the other hand, would see their after-tax income increase by 16%, and the top 1% would experience an after-tax income boost of 33%.

According to Kyle Pomerleau, director of federal projects at the Tax Foundation who authored the analysis, the only other 2016 presidential contender besides Carson whose tax plan would result in a net tax increase on any income group is one who is no longer in the race: Louisiana Governor Bobby Jindal.

"[Carson's plan] deviates from other Republican plans substantially," he said.

But individual Americans' losses could be corporate America's gains.

Under the doctor's proposal, corporations would see their tax rates lowered to 14.9% from the current 35%. Businesses would experience a change in the treatment of capital investments, meaning that when they buy a new machine or a factory or make other investments, they could fully deduct the costs of the purchases.

"This drastically reduces the cost of investment, and this is one of the biggest driving forces behind the economic growth in the Carson plan," Pomerleau said.

The Tax Foundation estimates Carson's plan would cut taxes by $5.6 trillion over the next decade but reduce revenues by only $2.5 trillion when accounting for economic growth, due to increase in the supply of labor and capital. Its model estimates it would lead to a 16% higher GDP over the long term (provided the cut be appropriately financed).

The organization's analysis determines the plan would put more money into the pockets of low and middle-income Americans as well -- provided they are willing to wait. It predicts 10.9% higher wages and 5.2 million more full-time jobs would eventually result from Carson's proposal.

Immediately, however, Carson's elimination of larger tax credits, including the child tax credit and earned income tax credit, would reduce the lowest-earners' income. And for the middle class, the eradication of itemized deductions and of the exemption of employer-provided health insurance would, in the near-term, hurt as well.

"Over a long period of time, the plan itself actually is very economically efficient and would increase the size of the economy. Over a long period of time, low-income households would recoup a lot of that because their wages would go up over time, but politically, it's a little difficult to say, 'Well, I'm going to raise your taxes this year by a lot, but I promise that in a long period of time, economic growth will make it even,'" Pomerleau said.

McIntyre was more pessimistic on whether economic growth would eventually reach the majority of Americans. "It's been tried for the last 40 years, and every time it fails, people who believe in it say, 'Wait until next year, and the rapture will happen,'" he said.
