Since the tax is still several years away, there’s a real possibility that the scope, application and timeframe may change. For now, it’s estimated that approximately 16 percent of all plans could be affected by the excise tax if it takes effect. The tax thresholds are linked to inflation, and medical spending and premiums historically grow faster than inflation, so eventually more plans will likely be affected. As the law stands, 75 percent of plans could be influenced by the tax within a decade.1
