April 15 is right around the corner, and millions of Americans will find themselves paying more in taxes than ever thanks to Obamacare.

The law is more than a fundamental change to the country’s health care system. It also is a massive tax hike. As The Heritage Foundation’s Federal Budget in Pictures shows, according to the most recent scores, Obamacare will increase taxes by nearly $800 billion for the period of 2013-2022.

Obamacare contains 18 separate tax increases. A few of the biggest include a tax on “Cadillac” health insurance plans, which doesn’t take effect until 2018, long after President Obama and many in Congress who voted for the tax in 2010 have departed Washington. Also, there is a tax on health insurance premiums and a higher rate on the Hospital Insurance payroll tax for single filers with incomes above $200,000 ($250,000 for married filers) that also applies to investment income.
