Answer:
A corporation can carry over the NOL indefinitely
Step-by-step explanation:
A net operating loss occurs when a companies tax payment exceeds its taxable income. Companies make this excess payment to offset future tax liabilities.
For example farms can generate much profit this year, but next year when they are offseason profits will be low. A NOL can be used to settle next year's tax liability.
After 2018 corporations can now carry forward NOL indefinitely as far as the NOL is not greater than 80% of previous year's income.
Before 2018 Corporations can carry NOLs back two years and forward up to 20 years.
