What is the typical cost seg ROI for a w-2 high earner (doctor, lawyer, executive) on a $750,000 property?

At a $750,000 depreciable basis, a typical cost segregation study reclassifies roughly $150,000 into 5-year personal property and $60,000 into 15-year land improvements, for a combined first-year deduction of $210,000 under 100% bonus depreciation. At a 32% combined federal and state marginal rate, the first-year tax savings are about $67,200.

What if I'm in a decoupled state?

If your state decouples from federal Section 168(k) bonus depreciation, you still capture the full federal benefit. The state-level benefit is reduced or eliminated and you add back the federal bonus deduction on your state return. See the state pages for state-specific treatment.

Should I wait until I have REPS?

Often not necessary. The losses you generate this year can offset other passive income, can suspend and carry forward indefinitely, or can offset W-2 income immediately if you qualify for the STR loophole. The decision depends on your year-by-year tax position. Run the 3-Bucket Decision Framework to choose.

Can I do this on a property I bought years ago?

Yes. A look-back study captures missed depreciation from prior years via Form 3115 (Designated Change Number 7) under Rev. Proc. 2022-14. The Section 481(a) catch-up adjustment posts in the year of change without amending prior returns.

What is the recapture exposure on a $750,000 property with cost seg?

On a $750,000 property with the reclassification above, the Section 1245 portion (5-year and 15-year basis, roughly $210,000) is subject to ordinary recapture at sale. The Section 1250 portion (the $540,000 on the long schedule) is subject to unrecaptured 1250 gain capped at 25%. A 1031 exchange defers all of it. A basis step-up at death under IRC Section 1014 eliminates it entirely.

Does the OBBBA Jan 19, 2025 cliff apply?

Yes. The cliff is a federal acquisition-date rule under amended IRC Section 168(k). Binding contracts on or before January 19, 2025 stay on the phase-down (40% bonus in 2025, 20% in 2026, 0% thereafter). Binding contracts on or after January 20, 2025 qualify for permanent 100% bonus depreciation under Public Law 119-21.

What service tier should I use?

For a $750,000 property, the appropriate WeCostSeg tier depends on residential vs commercial classification and basis size. Residential under $800K typically uses the $795 Rapid Report. Residential and small multifamily up to $2M basis uses the $2,495 Fully Engineered Residential. Commercial of any size uses the $2,995+ Fully Engineered Commercial. All tiers include five years of audit defense.

Is Cost Segregation Worth It on a $500K-$1M Property for a W-2 high earner (doctor, lawyer, executive)?

By Zawwad Ul Sami, Founder, WeCostSegPublished: 2026-05-14Last updated: 2026-05-14

For a w-2 high earner (doctor, lawyer, executive) (high w-2 income $400k+; can offset w-2 if str loophole or reps qualified) considering cost segregation on a $750,000 property, the math and the loss-usability question both matter. The math below uses industry-typical 5-year and 15-year allocations from IRS Publication 5653 guidance. The usability question depends on your tax profile.

The math on a $750,000 property

A cost segregation study on a $750,000 property typically reclassifies about 28% of the depreciable basis into accelerated recovery periods, splitting between 5-year personal property and 15-year land improvements. Under 100% bonus depreciation per OBBBA, the reclassified portion deducts entirely in the first year. The remaining basis stays on the standard 27.5-year residential or 39-year nonresidential schedule.

Depreciable basis: $750,000
5-year reclassification (about 20%): $150,000
15-year reclassification (about 8%): $60,000
Total first-year deduction at 100% bonus: $210,000
Remainder on standard recovery (27.5 or 39-year): $540,000
Estimated tax savings at 32% combined rate: $67,200
Estimated tax savings at 37% top combined rate: $77,700

The exact reclassification percentages depend on property type, condition, age, and local construction characteristics. A property-specific engineering study can push the reclassified portion higher than the 28% baseline shown above. The above is a conservative midpoint useful for a first-pass economic decision before commissioning the engineering work.

Can a w-2 high earner (doctor, lawyer, executive) actually use the loss?

Only against other passive income, unless you also qualify for the STR loophole or REPS. A high W-2 alone does not unlock passive rental losses.

Whether the rental loss generated by cost segregation is usable depends on the interaction between IRC Section 469's passive activity loss rules and the taxpayer's specific profile. For a w-2 high earner (doctor, lawyer, executive), the analysis turns on the specific characteristics of the holding entity, the taxpayer's other income, and whether they meet REPS qualification or the STR loophole criteria. The cost seg deduction is real regardless of usability. Usability determines whether the deduction applies against current-year income or suspends as a carryforward.

For a w-2 high earner (doctor, lawyer, executive) who cannot use the loss this year, the deduction does not disappear. It suspends under Section 469(b) and carries forward indefinitely until the taxpayer has passive income, qualifies for one of the exceptions, or fully disposes of the activity under Section 469(g). Many investors generate large suspended losses through cost seg in the acquisition year, then release them at disposition against the recapture income, partially neutralizing the recapture cost.

The 3-Bucket Decision Framework on this scenario

The WeCostSeg 3-Bucket Decision Framework asks whether the property meets one of three buckets: basis above $300K with bonus-eligible placed-in-service date, qualifying STR with material participation, or REPS-qualified taxpayer. The basis here clears Bucket 1's threshold. Bucket 2 (STR) does not apply unless this is a short-term rental with material participation. Bucket 3 (REPS) requires the 750-hour and more-than-half tests.

Alternative strategies if cost seg does not pencil here

Bundle cost seg with the next property purchase to build basis above $300K before engaging.
Pursue STR loophole qualification by acquiring a short-term rental and meeting the material-participation tests.
Track REPS hours contemporaneously, then run cost seg in the first year REPS qualifies.
Use Section 179 expensing for personal property where applicable (capped at $2.5M under OBBBA).
