Excess Business Loss Limitation for STR Hosts
No credit card required
Under IRC §461(l), aggregate business losses are capped at $256,000 for single filers and $512,000 for married filing jointly in 2026. That is lower than the 2025 thresholds of $313,000 and $626,000, because the One Big Beautiful Bill Act made the limitation permanent and reset the inflation base at the same time. For STR hosts who use cost segregation and bonus depreciation to generate large deductible losses, this provision can limit how much of those losses offset W-2 income — with excess amounts carried forward as an NOL.
What Is the Excess Business Loss Limitation?
IRC §461(l) was introduced by the Tax Cuts and Jobs Act (TCJA) of 2017, extended through 2028 by the Inflation Reduction Act, and made permanent by the 2025 reconciliation act (the One Big Beautiful Bill Act). It limits how much aggregate business loss a non-corporate taxpayer can deduct in a single year.
For tax year 2026, the thresholds are set by Revenue Procedure 2025-32, section 4.31:
- Single / MFS: $256,000 (2025: $313,000)
- Married Filing Jointly: $512,000 (2025: $626,000)
Business losses above these amounts become an "excess business loss" that is not deductible in the current year. Instead, it is treated as a net operating loss (NOL) that carries forward to future years.
How This Affects STR Hosts
Most STR hosts never hit these thresholds — the limitation primarily affects hosts who:
- Own multiple high-value STR properties
- Have commissioned a cost segregation study that dramatically accelerates depreciation
- Took bonus depreciation in the year of acquisition, generating a very large paper loss
- Also earn significant W-2 income that they want to offset with STR losses
For example: a host with $500,000 in W-2 income who also generates an $800,000 active business loss from cost segregation on a commercial STR property would be capped at $256,000 (single) of deductible loss for 2026. The remaining $544,000 becomes an NOL carryforward. Under the 2025 threshold the same host could have deducted $313,000, so the reset costs this taxpayer $57,000 of current-year deduction.
Active Business Losses vs. Schedule E: Which Losses Are Affected?
This is an important distinction. The §461(l) limitation applies to business losses — not passive rental losses.
- active STR losses (material participation, active business) = subject to §461(l)
- Schedule E passive rental losses = NOT subject to §461(l), but subject to the $25,000 passive activity loss allowance and passive activity rules instead
The §461(l) limitation is relevant specifically to the high-income STR hosts who claim material participation and operate their rentals as active businesses — and then use aggressive depreciation strategies to generate losses that offset other income.
The §461(l) limitation applies after other loss limitation rules. For STR losses to reach §461(l), they must first survive the at-risk rules (IRC §465) and passive activity rules (IRC §469). Only losses that have already cleared those hurdles are then potentially subject to the §461(l) cap.
NOL Carryforward: The Loss Isn't Gone
Excess business losses that hit the §461(l) cap are not permanently lost — they become an NOL carryforward. Key characteristics:
No credit card required
- NOLs from §461(l) excess losses carry forward indefinitely (no expiration)
- In the carryforward year, the NOL can offset up to 80% of taxable income
- You track NOL carryforwards on Form 8995-A or Form 1045
- NOLs from different years can be used in any order in future years
Legislative Status: One Big Beautiful Bill Act
This is settled now, and it went against high-loss taxpayers. The One Big Beautiful Bill Act, enacted in July 2025, made the §461(l) limitation permanent rather than letting it expire, and reset the inflation base used to index the thresholds. The practical effect is the drop shown above: the 2026 cap is $57,000 lower for single filers and $114,000 lower for joint filers than it was in 2025, erasing several years of accumulated inflation adjustments.
Planning that assumed the threshold would keep drifting upward each year needs revisiting. The thresholds are still indexed going forward, so they will rise again from the new, lower base. Verify the current-year figure with your CPA before making decisions that turn on it — the IRS publishes it each autumn in the annual inflation-adjustment revenue procedure.
Planning Strategies for High-Loss STR Hosts
Spread Cost Segregation Benefits Over Multiple Years
Rather than triggering all bonus depreciation in a single year, you may be able to elect out of bonus depreciation for certain assets and use regular MACRS depreciation to spread the deductions over multiple years — staying below the §461(l) cap in each year.
Acquire Additional Properties to Absorb Losses
Additional STR income in future years can be offset by the NOL carryforward — so the deferred loss isn't wasted, it just arrives on a different timeline.
Maximize Other Deductible Business Income
Losses are more valuable when they offset income subject to the highest marginal rates. Planning the timing of large deductions alongside high-income years maximizes their value even with the §461(l) cap.
If you're approaching or expecting to exceed the §461(l) threshold, run projections with your CPA before December 31. Year-end decisions — whether to accelerate or defer a large expense, whether to elect out of bonus depreciation on specific assets, or whether to recognize additional income — can have significant effects on how the limitation applies in the current year.

Frequently Asked Questions
What is the excess business loss limitation for 2026?
Under IRC §461(l), the excess business loss limitation for 2026 is $256,000 for single filers and $512,000 for married filing jointly, per Revenue Procedure 2025-32. Note that this is lower than 2025 ($313,000 and $626,000): the One Big Beautiful Bill Act made the limitation permanent and reset the inflation base, so the threshold fell rather than rose. Business losses above these thresholds cannot be deducted in the current year and are carried forward as a net operating loss (NOL).
Does the excess business loss limitation apply to STR hosts?
Yes, but only to STR losses generated through material participation (active business losses, reported on your tax return). Passive rental losses on Schedule E are subject to the passive activity rules instead and are not 'business losses' for §461(l) purposes. The §461(l) cap is most relevant for high-income STR hosts who use cost segregation and bonus depreciation to generate large deductible losses.
What happens to excess business losses above the §461(l) cap?
Excess business losses above the cap become a net operating loss (NOL) that is carried forward to future tax years. The NOL can offset up to 80% of taxable income in the carryforward year. The loss is not lost — it is simply deferred to a future year when you may have income to offset.
