Does Your State Have a Throwback or Throwout Rule?
The text discusses state throwback and throwout rules, which are tax policies that can increase corporations’ tax liability and influence business decision-making. Throwback rules involve sales of tangible property being “thrown back” into the state where the sale originated, increasing the numerator of the apportionment formula and the tax liability for corporations. Meanwhile, throwout rules exclude certain sales from the denominator of the apportionment formula, also increasing tax liability. These rules can erode the competitiveness of states and incentivize businesses to relocate to avoid higher tax burdens.
