Note on US Federal NOL Rules (Post-2017 Losses):
- NOLs generated in tax years beginning after Dec 31, 2017, generally cannot be carried back (exceptions apply for certain farming losses and insurance companies).
- These NOLs can be carried forward indefinitely.
- The NOL deduction in any tax year is limited to 80% of your taxable income (calculated before the NOL deduction).
- This calculator models the carryforward and 80% limitation for NOLs generated in 2018 or later. It assumes no carryback is applicable.
- Consult a qualified tax professional for advice specific to your situation, as complex rules, exceptions, and potential legislative changes may apply.
