The Grover Norquist-founded Americans for Tax Reform, a 501(c)(4) lobbying group that opposes “all tax increases as a matter of principle,” on Friday released a list of what, they say, are the top five worst taxes The Patient Protection and Affordable Care Act (i.e. “Obamacare”) will impose on Americans in 2013.

Here they are [all block quotes via the report]:

The ‘Obamacare’ Medical Device Tax

Americans For Tax Reform Releases a List of the Top 5 Worst Taxes Obamacare Will Impose in 2013Tax Increase: $20 Billion

Medical device manufacturers employ 409,000 people in 12,000 plants across the country. Obamacare imposes a new 2.3 percent excise tax on gross sales — even if the company does not earn a profit in a given year. In addition to killing small business jobs and impacting research and development budgets, this will increase the cost of your health care — making everything from pacemakers to prosthetics more expensive.

The ‘Obamacare’ ‘Special Needs Kids Tax’

The 30-35 million American who use a Flexible Spending Account (FSA) at work to pay for their family’s basic medical needs will face a new government cap of $2,500 (currently the accounts are unlimited under federal law, though employers are allowed to set a cap).

There is one group of FSA owners for whom this new cap will be particularly cruel and onerous: parents of special needs children.  There are several million families with special needs children in the United States, and many of them use FSAs to pay for special needs education. Tuition rates at one leading school that teaches special needs children in Washington, D.C. (National Child Research Center) can easily exceed $14,000 per year. Under tax rules, FSA dollars can be used to pay for this type of special needs education. This Obamacare tax provision will limit the options available to these families.

The ‘Obamacare’ Surtax on Investment Income

This is a new, 3.8 percentage point surtax on investment income earned in households making at least $250,000 ($200,000 single).  This would result in the following top tax rates on investment income:

The table above also incorporates the scheduled hike in the capital gains rate from 15 to 20 percent, and the scheduled hike in dividends rate from 15 to 39.6 percent.

The ‘Obamacare’ ‘Haircut’ for Medical Itemized Deductions

Americans For Tax Reform Releases a List of the Top 5 Worst Taxes Obamacare Will Impose in 2013Tax Increase: $15.2 Billion

Currently, those Americans facing high medical expenses are allowed a deduction to the extent that those expenses exceed 7.5 percent of adjusted gross income (AGI).  This tax increase imposes a threshold of 10 percent of AGI. By limiting this deduction, Obamacare widens the net of taxable income for the sickest Americans.  This tax provision will most harm near retirees and those with modest incomes but high medical bills.

The ‘Obamacare’ Medicare Payroll Tax Hike

The Medicare payroll tax is currently 2.9 percent on all wages and self-employment profits.  Under this tax hike, wages and profits exceeding $200,000 ($250,000 in the case of married couples) will face a 3.8 percent rate instead. This is a direct marginal income tax hike on small business owners, who are liable for self-employment tax in most cases. The table below compares current law vs. the Obamacare Medicare Payroll Tax Hike:
