The Excess Business Loss (EBL) limitation under Section 461(l) continues to impact U.S. individual taxpayers in 2025. With thresholds of $313,000 for single filers and $626,000 for joint filers, knowing what qualifies, what gets deferred, and how to complete Form 461 is essential for tax compliance and planning.
Section 461(l) was enacted to prevent noncorporate taxpayers from using large business losses to wipe out non-business income (like wages, dividends, or capital gains). For 2025, the IRS confirmed inflation-adjusted thresholds of:
- $313,000 for single taxpayers or married filing separately
- $626,000 for married filing jointly
Any business loss above these amounts is treated as an Excess Business Loss and must be carried forward as a Net Operating Loss (NOL), subject to the 80% taxable income limitation in future years.

📌 What Counts Toward Excess Business Loss?
The IRS aggregates all trade or business income and deductions reported on:
- Schedule C (sole proprietorships)
- Schedule E (rental activities, partnerships, and S corporations)
- Schedule F (farm income and losses)
Losses above the $313k/$626k threshold are disallowed for the year. These deferred losses are automatically carried forward as part of an NOL, applied under future taxable income limits.

📑 Walkthrough of Form 461
Form 461, Limitation on Business Losses, is required if your business deductions exceed business income plus the threshold. Key steps include:
- Part I: Enter total business income, gains, and losses from Schedules C, E, and F.
- Part II: Apply adjustments for NOLs and capital loss limitations.
- Part III: Subtract the allowable threshold ($313,000 or $626,000).
- Result: Any disallowed portion becomes an NOL carryforward to the next tax year.
The form ensures accurate tracking and reporting of deferred business losses so they can be applied properly against future income.
