Net Operating Loss (NOL) Carrybacks

  • The CARES Act (Public Law 116-136) expanded the NOL carryback period to 5 years for losses incurred in 2018, 2019, and 2020. However, on the Missouri tax return, taxpayers must add back into taxable income any NOL that is carried back more than 2 years from the loss year. A NOL that was added back into taxable income may then be carried forward to a tax year after the loss year (up to 20 years). For further details, see section 143.121.2(4) of the Missouri Revised Statutes.
