US Federal Net Operating Loss (NOL) Carryforward Calculator
This tool calculates carryforward for NOLs generated in Tax Years 2018 or later, which are generally subject to the 80% taxable income limitation and have an indefinite carryforward period.
Enter Carryforward Year Details
Enter the taxable income *before* considering any NOL deduction for each subsequent year you wish to apply the NOL. Add years in chronological order for clarity, though the tool will sort them for calculation.
Years Added for Calculation:
- No years added yet.
Calculation Results:
Enter NOL details and carryforward years in the other tabs, then click "Calculate Carryforward".
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.
