Answer:
$450,000
Step-by-step explanation:
during 2017, Theodore Enterprises reported a $900,000 loss = $300,000 net carryover, but since they decided to elect a loss carryback, those $300,000 went to reduce the payment of 2016 taxes (that were probably overdue).
That means that the company had no carryover left for 2018 taxes = $1,500,000 x 30% = $450,000
A carryover happens when a company chooses to carry a loss forward, while a carryback happens when the company chooses to reduced previous taxes with the current loss.
