Business Loss (NOL) Carryforward Calculator (USA)
This tool helps estimate how much of a prior year's Net Operating Loss (NOL) can be used to reduce taxable income in a current year, based on current U.S. federal tax rules.
Current NOL Carryforward Rules (Post-TCJA for most losses):
- Most NOLs generated in tax years ending after 2017 cannot be carried back (with exceptions).
- NOLs can generally be carried forward indefinitely.
- The NOL deduction for any tax year beginning after 2020 is generally limited to **80% of your taxable income** before the NOL deduction.
This tool applies the 80% limitation to estimate NOL usage and carryforward. It does not account for all complex NOL rules or exceptions. Consult a tax professional for specific advice.
