What is the excess business loss limitation for 2026?

Under IRC §461(l), the excess business loss limitation for 2026 is approximately $305,000 for single filers and $610,000 for married filing jointly (amounts are inflation-adjusted annually). 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 Schedule C). 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.

Excess Business Loss Limitation for STR Hosts

Under IRC §461(l), enacted by the Tax Cuts and Jobs Act, aggregate business losses are capped at approximately $305,000 for single filers and $610,000 for married filing jointly in 2026. 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 and made permanent by the Inflation Reduction 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 approximately:

Single / MFS: $305,000
Married Filing Jointly: $610,000

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 Schedule C loss from cost segregation on a commercial STR property would be capped at $305,000 (single) of deductible loss. The remaining $495,000 becomes an NOL carryforward.

Schedule C vs. Schedule E: Which Losses Are Affected?

This is an important distinction. The §461(l) limitation applies to business losses — not passive rental losses.

Schedule C 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 on Schedule C — and then use aggressive depreciation strategies to generate losses that offset other income.

Order of Limitations

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:

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

As of early 2026, various proposals in Congress would modify or eliminate the §461(l) limitation. The "One Big Beautiful Bill Act" includes provisions that could affect business loss rules. These proposals are subject to change — verify the current status with a CPA before making significant tax planning decisions that depend on specific §461(l) thresholds.

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.

Model It Before Year-End

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.
