Understanding Tax Net Operating Losses (NOL)

by | Aug 19, 2025 | Tax

In the unpredictable world of business and personal finance, income can vary dramatically year to year. Whether driven by economic challenges, startup investments, or unforeseen events, these fluctuations may result in financial setbacks. When allowable deductions exceed income, the result is a Net Operating Loss (NOL). Strategically leveraging NOLs can provide valuable tax relief and bolster financial recovery. 

What is Net Operating Loss (NOL)?  

A Net Operating Loss occurs when a taxpayer’s allowable deductions exceed their taxable income within a given tax year. For businesses, this typically results from operating expenses surpassing revenues. For individuals, NOLs can arise from pass-through business activities, casualty and theft losses, or certain deductions exceeding income.  

The Strategic Value of NOLs  

For Businesses  

  • Cash Flow Management: NOLs can be carried forward to offset future taxable income, reducing tax liabilities in profitable years and preserving cash.  
  • Tax Planning Flexibility: Strategic use of NOLs allows businesses to manage earnings volatility, especially in cyclical industries like manufacturing, energy, or retail.  
  • Investment Incentives: Startups and growth-stage companies often incur early losses. NOLs provide a future tax shield, making them more attractive to investors.  

For Individuals  

  • Pass-Through Entities: Owners of S corporations, partnerships, or sole proprietorships can use NOLs to offset other income, reducing overall tax burdens.  
  • Estate and Retirement Planning: NOLs can be integrated into broader financial strategies, such as timing the realization of capital gains or Roth conversions.  
  • Disaster Recovery: Individuals affected by federally declared disasters may generate NOLs from casualty losses, offering a form of tax relief during recovery.  

How to Utilize NOLs 

The IRS provides guidance on how both businesses and individuals can use Net Operating Losses (NOLs) to reduce future tax liabilities. According to IRS Publication 536, if your deductions for the year exceed your income, you may have an NOL. Here are the key steps to utilize it:  

Determine the NOL Year: The year in which the NOL occurs is known as the NOL year. You must calculate the NOL using IRS worksheets to determine eligibility and the amount.  

Carryforward Rules: For most taxpayers, NOLs arising in tax years ending after 2020 can only be carried forward to offset income in future years. The NOL can be carried forward indefinitely to subsequent taxable years. Certain exceptions apply, such as for farming losses, which may be carried back two years.  

NOL Deduction Limitation: For tax years beginning after December 31, 2020, the NOL deduction is limited. You can deduct the full amount of NOLs from pre-2018 tax years, but for post-2017 NOLs, the deduction is limited to 80% of your taxable income (calculated without the NOL deduction).  

Annual Losses Limited: The Tax Cuts and Jobs Act (TCJA), as amended by the CARES Act, and as further amended by the Inflation Reduction Act, limits the amount of losses from the trades or businesses of noncorporate taxpayers that the taxpayer can claim each year, beginning after 2020 and ending before 2029. Businesses cannot deduct net losses in excess of a threshold amount in the current year. The amount of the excess business loss is treated as an NOL for the current year for purposes of determining any NOL carryover for later tax years.  

Filing Requirements: Individuals typically use Form 1045 (Schedule A) or Form 1040-X to claim NOL carryforwards. Businesses may need to include additional schedules or disclosures depending on their structure.  

Key Considerations  

For Businesses  

  • Tax Rate Timing: Apply NOLs in high-tax years to maximize value.  
  • Ownership Changes: Be aware of IRC Section 382 limits after mergers or acquisitions.  
  • State Variability: NOL rules differ by state. Not all states follow federal NOL provisions.  Som states are more or less restrictive than federal rules. Some states have suspended the NOL deduction and do not all the deduction at all. 
  • Financial Reporting: NOLs affect deferred tax assets and can influence investor perception.  

For Individuals  

  • Eligible Sources: NOLs must come from allowable sources like business or casualty losses—not capital losses.  
  • Tax Interaction: NOLs don’t offset all income types (e.g., capital gains), so plan accordingly.  
  • Filing Accuracy: Use correct forms and understand timing for carrybacks or amended returns.  
  • AMT Impact: NOLs may be limited under the Alternative Minimum Tax.
