Gimmick No. 1 is the way the bill front-loads revenues and backloads spending. That is, the taxes and fees it calls for are set to begin immediately, but its new subsidies would be deferred so that the first 10 years of revenue would be used to pay for only 6 years of spending.

Even worse, some costs are left out entirely. To operate the new programs over the first 10 years, future Congresses would need to vote for $114 billion in additional annual spending. But this so-called discretionary spending is excluded from the Congressional Budget Office’s tabulation.

Consider, too, the fate of the $70 billion in premiums expected to be raised in the first 10 years for the legislation’s new long-term health care insurance program. This money is counted as deficit reduction, but the benefits it is intended to finance are assumed not to materialize in the first 10 years, so they appear nowhere in the cost of the legislation.

Another vivid example of how the legislation manipulates revenues is the provision to have corporations deposit $8 billion in higher estimated tax payments in 2014, thereby meeting fiscal targets for the first five years. But since the corporations’ actual taxes would be unchanged, the money would need to be refunded the next year. The net effect is simply to shift dollars from 2015 to 2014.

In addition to this accounting sleight of hand, the legislation would blithely rob Peter to pay Paul. For example, it would use $53 billion in anticipated higher Social Security taxes to offset health care spending. Social Security revenues are expected to rise as employers shift from paying for health insurance to paying higher wages. But if workers have higher wages, they will also qualify for increased Social Security benefits when they retire. So the extra money raised from payroll taxes is already spoken for. (Indeed, it is unlikely to be enough to keep Social Security solvent.) It cannot be used for lowering the deficit.
