If you received a subsidy for Obamacare coverage, there’s a 50-50 chance you’ll have to pay some of it back come tax-time.

It doesn’t come as much of a surprise that HealthCare.gov’s estimates may have been inaccurate. “The poorly-written ObamaCare website had to interface with numerous other government and insurance-industry computer systems to calculate subsidies and give shoppers a bottom-line price with Everybody Else’s share paid off,” says John Hayward. There were bound to be errors.

Further, the estimates were based on projected income. These two factors combined mean that half of the people who received subsidies for their healthcare were given too much – and 3.4 million people could actually owe money back to the IRS for the website’s miscalculation.

Vanderbilt University assistant professor John Graves projects the average subsidy is $208 too high. H&R Block also estimated the damage and is preparing for a lot more angry customers this tax season.

The anger will be much-deserved. Americans have been fed lie after lie about the President’s healthcare system. Now it joins teams with the IRS, a government entity even less-liked than Obamacare.

Hayward says this will also illuminate the flaws in our tax system itself. We should be angry every year at the government’s “neat trick of bribing people with their own money – teaching them to think of the annual tax rebate as a ‘gift’ from the friendly Leviathan State, rather than money taken by the government over the course of a year and returned without interest.” Neither do we think about the loss of productivity and profit when countless hours must be consumed just to sort out the tax law.

The U.S. tax system will only continue to take more from American citizens unless something drastic is done to stop it. And it won’t be done simply by program revision. The IRS is one symptom of a whole-government problem, encroaching on our citizens’ rights and telling them they can’t do anything about it.

The truth is, we can. Our Constitution provides an escape clause in Article V, giving the people the right to call for a Convention of States to amend the Constitution and rein in the power of an out-of-control federal government.

This is the only solution that can address the heart of the problem instead of putting band-aids on individual symptoms. Learn more at ConventionofStates.com.
