Enacted in 2001, this provision originally allowed businesses to deduct 30% of their costs of new
depreciable assets. The purpose was to keep the economy from a recession after the September 11
terrorist attacks. The provision has remained in effect since, but the deductible amount was increased to
50% of costs in 2003 or so, then to 100% for a few years, after which it went back to 50%. The Tax Cuts
and Jobs Act passed in December of 2017 increased it to 100% again. Many states allow this deduction in
full, others disallow it entirely, and some states adjust the federal deduction.
