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.

In the USA, incurring a business loss for a tax year doesn’t always mean that money is lost forever for tax purposes. A Net Operating Loss (NOL) can be a powerful tool to reduce your taxable income in future profitable years. Our free Business Loss Carryforward Calculator is designed to help you understand and estimate your NOL, allowing for better tax planning and cash flow management.
A Net Operating Loss (NOL) occurs when your allowable business deductions exceed your taxable income for the year. Instead of just having zero taxable income, the IRS generally allows you to “carry forward” this loss to offset future profits.
For NOLs generated in tax years beginning after December 31, 2017 (and specifically after December 31, 2020), the key rules are:
Indefinite Carryforward: NOLs can be carried forward indefinitely, meaning no expiration date.
80% Taxable Income Limitation: You can generally only use an NOL to offset up to 80% of your taxable income in any future year. This means you can’t reduce your taxable income to zero using only post-2017 NOLs.
No Carrybacks (Generally): For most businesses, NOLs arising after 2017 cannot be carried back to offset income in previous years. Farming losses are a notable exception, with a two-year carryback.
Excess Business Loss Limitation: Noncorporate taxpayers (like sole proprietors or partners) might have “excess business losses” that are treated as an NOL carryforward, further complicating calculations.
Our calculator helps you input your business income and expenses to determine your estimated NOL and how it might apply in subsequent years. This foresight is crucial for managing your financial obligations and ensuring compliance with US tax laws.
