NOLs arising in tax years beginning in 2018, 2019, and 2020 may be carried back for a period of five years and carried forward indefinitely. A taxpayer may elect to forego the carryback.
Generally, an NOL arising in a tax year beginning in 2021 or later may not be carried back and instead must be carried forward indefinitely. However, farming losses arising in tax years beginning in 2021 or later may be carried back two years and carried forward indefinitely. NOLs of non-life insurance companies arising during these years may also be carried back two years and carried forward 20 years.
