One can certainly see why ending tax deductions for punitive damages is a superficially appealing idea.
But the main effect will be to increase settlement pressure in cases where there are unjust punitive damages awards. Because settlements can be characterized as “compensatory” and tax-deductible while court-ordered judgments cannot, trial lawyers will be able to use the tax differential to discourage defendants from seeking appellate review. So one cannot expect very much tax revenue from this: “punitive damages” will drop precipitously, but money going to trial lawyers will go up. Moreover, appellate courts will have fewer opportunities to correct bad decisions by trial courts, creating more uncertainty in litigation, which raises litigation expenses because it will be harder to predict outcomes.
Note that taxpayers are not subsidizing punitive damages award deductions by businesses: the income “lost” because a defendant deducted the punitive damages award will be income realized by the plaintiff and his or her attorney. If the deduction is forbidden, the government will be, in effect, double-taxing the same money.
The Obama administration makes much of its claim of being pragmatic, rather than ideological, but this looks like an indirect giveaway to the trial bar rather than a source of government revenue. More: Walter at Point of Law; and my shining mug quoted at the Southeast Texas Record.
