I say *temporary* funding because the corporate AMT is generally an acceleration of regular tax liability. If a corporation pays the AMT, a credit against future corporate regular tax is carried forward. Congress likes to complain about corporations artificially carrying forward financial book income and postponing taxable income. Here, Congress is engaging in the same sort of shenanigan by accelerating current tax revenues at the cost of future revenue. The JCT only estimates additional revenue over a 10-year period. What they don’t report is that the AMT revenue during the first 10 years will reduce tax revenues in the years thereafter. It’s not completely zero sum, but mostly zero sum over a longer period of time.
