- US cost-segregation pricing in 2026 spans 30× — from $495 to $15,000+ — for studies that produce comparably defensible reports. The methodology (RSMeans 2024 + MACRS per Rev. Proc. 87-56 + IRS ATG framework) is shared across all credible firms. The labor model is what differs.
- The market has stratified into three tiers: automated/DIY ($495–$2,995), mid-tier traditional ($3,000–$8,000), and major firms ($5,000–$15,000+). Each tier is genuinely built for a different property segment. Automated for residential and small-commercial under $5M; mid-tier for mid-market commercial $1M–$5M; major firms for $5M+ commercial with specialty assets.
- For a typical $500K residential property, the price differential between automated and major-firm tiers is roughly $4,200 ($795 vs. $5,000+) for the same defensible report. That differential — not the engineering — is what determines whether the math pencils on residential properties under $1M.
Cost segregation has been a US tax strategy since the 1997 Hospital Corporation of America v. Commissioner ruling, and the methodology has been standardized for decades. Yet pricing varies by 30× across credible providers — a span that's hard to find in any other professional-services market. This report explains why.
We compiled pricing data on eight US cost-segregation providers — KBKG, Madison SPECS, Engineered Tax Services, ELB Consulting, CSSI, Bedford Cost Segregation, KBKG Residential Cost Segregator (DIY), and Cost Seg Smart — across residential and commercial property tiers. The dataset is licensed CC-BY 4.0; anyone can use, share, or republish with attribution.
Methodology
Pricing data was compiled from three sources: (1) provider websites and public pricing schedules where published; (2) customer-reported pricing across our network of CPA referral partners and tax-prep professionals as of Q1–Q2 2026; (3) our own internal pricing schedule for Cost Seg Smart. We've cited typical mid-range prices rather than negotiated outliers. Where a provider's published schedule and customer-reported pricing diverge materially, we've noted both.
Property tiers in this analysis follow the segmentation Cost Seg Smart uses internally:
- Residential: single-family rental (SFR), short-term rental (STR), condo, multifamily 2-4 unit.
- Commercial: office, medical office, retail, restaurant, mixed-use, industrial, multifamily 5+ unit.
- Property tiers: sub-$300K, $300K–$700K, $700K–$1M, $1M–$2M, $2M–$5M, $5M–$15M, $15M+.
The three tiers of the cost-seg market
The structure of the US cost-segregation market in 2026 mirrors the structure of any professional-services market that's been around long enough to stratify: the largest and most complex engagements anchor a high-end tier, mid-market specialists fill the middle, and lower-cost productized alternatives serve the long tail.
Tier 1: Major firms ($5,000–$15,000+)
Examples: KBKG, Madison SPECS, Engineered Tax Services. These firms are built for $5M+ commercial work and the engagement structure reflects that. A typical engagement: discovery call, scheduled on-site engineer visit (often with travel time and overnight accommodation), 4–8 week timeline, manual report drafting from scratch, white-glove project management. Pricing scales with property complexity — a $10M hospitality property may run $15K–$25K; a Class-A office building can exceed $30K for the most rigorous engagements.
This tier's value isn't the methodology (which is the same as everyone else's). It's the on-site engineering judgment that captures custom assets, specialty MEP, ground-up commercial construction details, and property-specific features that aren't visible in public records. For $5M+ commercial properties with specialty assets, that judgment materially affects the schedule. For residential and small-commercial under $5M, it doesn't — which is why major firms typically don't profitably quote that segment.
Tier 2: Mid-tier traditional firms ($3,000–$8,000)
Examples: ELB Consulting, Cost Segregation Services Inc. (CSSI), Bedford Cost Segregation, and similar. Established specialty engineering firms with 10–20+ years in the market. Engagement model is broadly traditional — discovery call, often an on-site or hybrid engineer review, 3–6 week timeline, engineer-attested reports. The labor structure is leaner than major firms (smaller bench, lower overhead), so they can profitably quote properties starting at $1M commercial or $750K residential.
This tier serves mid-market commercial owners who want a small-firm engagement relationship with named project management and direct engineer access. CPAs in mid-market commercial circles often have established referral relationships with specific mid-tier firms based on documentation quality and audit-defense track record. The price-to-defensibility ratio is genuinely better than the major-firm tier for properties in the $1M–$5M commercial range. Below $1M, the tier becomes hard to justify economically against automated alternatives at the same defensibility.
Tier 3: Automated and DIY ($495–$2,995)
Examples: Cost Seg Smart (automated, done-for-you with engineer review), KBKG Residential Cost Segregator (DIY software). This tier didn't exist as a credible engineering option until ~2020 — the methodology had been standardized for decades, but no one had productized it for residential and small-commercial properties. Two paths emerged: automated providers like Cost Seg Smart that apply the methodology to structured property data with engineer review on outliers, and DIY tools that give the customer the framework and let them drive the analysis.
Both serve residential and small-commercial under $5M. The automated path delivers in under 60 minutes with engineer attestation; the DIY path takes 2–4 hours of customer time and ships customer-prepared reports. Pricing converges around $495–$799 for residential, with automated providers running up to $2,995 for commercial under $15M. The methodology is the same as the higher tiers; the labor model is what's compressed.
Per-segment median pricing tables
The following tables show typical residential and commercial pricing across the three market tiers as of May 2026. Where a provider doesn't typically quote a given segment, we've marked the cell "—".
Residential pricing (SFR, STR, condo, MF 2-4 unit)
| Purchase price tier | Cost Seg Smart | KBKG Residential (DIY) | Mid-tier (ELB/CSSI/Bedford) | Major firms (KBKG/Madison/ETS) |
|---|---|---|---|---|
| Under $300K | $495 | ~$499 | — | — |
| $300K–$700K | $795 | ~$499–$799 | $3,000–$5,000 | ~$5,000+ |
| $700K–$1M | $895 | ~$799 | $3,500–$6,000 | ~$5,000+ |
| $1M–$2M | $1,295 | ~$799–$1,499 | $4,000–$7,000 | ~$5,000+ |
| $2M–$5M | $1,595 | ~$1,499–$2,499 | $5,000–$8,000 | $7,000+ |
| $5M+ | $1,895 | — | — | $8,000–$15,000+ |
DIY (KBKG Residential Cost Segregator) pricing reflects subscription-based per-property usage; actual pricing depends on plan. Mid-tier and major-firm pricing reflects typical residential quotes when these tiers take residential engagements.
Commercial pricing (office, retail, restaurant, MF 5+, industrial, mixed-use)
| Purchase price tier | Cost Seg Smart | Mid-tier traditional | Major firms |
|---|---|---|---|
| $300K–$1M | $995 | $3,500–$6,000 | ~$5,000+ |
| $1M–$2M | $1,395 | $4,000–$7,000 | $5,000–$8,000 |
| $2M–$5M | $1,895 | $5,000–$8,000 | $7,000–$12,000 |
| $5M–$15M | $2,495 | $7,000–$12,000 | $10,000–$20,000+ |
| $15M+ | $2,995 | $10,000+ | $15,000–$50,000+ |
Major-firm pricing for hospitality, healthcare specialty, and ground-up commercial above $15M can substantially exceed $50K depending on engagement complexity. Cost Seg Smart automated pipeline halts on multi-parcel coordinated acquisitions and routes to manual review; pricing for those engagements is custom-quoted.
Why the spread exists
Three structural factors explain the 30× pricing range:
1. Labor concentration
A traditional cost-segregation engagement at the major-firm tier involves a project manager, a licensed engineer (often two — primary plus reviewer), an on-site visit (with travel and overnight if remote), manual cost-database lookups against multiple RSMeans line items, hand-built MACRS schedule, custom-written report (typically 60+ pages with property-specific photos and evidence), and dedicated audit-defense packaging. That's 30–80 person-hours per engagement at $200–$400/hour blended labor cost. Even at modest margins, the labor floor is $5K–$8K before overhead.
Automated providers like Cost Seg Smart apply the same methodology to structured property data — county assessor records, RentCast property API, OSM building classification, satellite imagery, RSMeans 2024 cost library, BLS PPI time index. The deterministic 90% of the workflow runs in seconds; engineer review concentrates on outliers via a 16-check QC gate. Per-engagement labor drops to ~5–15 minutes for typical residential, $0.10–$5.00 in compute and data access. The labor floor is a 90× reduction, which is what enables the price differential.
2. Property segmentation
The major-firm tier is built for $5M+ commercial. Their engagement structure (discovery call, scheduled on-site visit, multi-week project management) doesn't scale down to residential. A residential cost-seg engagement at major-firm pricing has economics that work for the firm but not for the property owner — the study fee consumes the Year-1 benefit. So major firms exit the residential market by quoting it out of profitability, not by being unable to do the work technically. The market then opened a gap that automated providers fill.
3. On-site engineering value
For the segment where on-site engineering genuinely matters — $5M+ commercial with specialty assets, hospitality with food-and-beverage build-out, ground-up commercial new construction, custom MEP — the major-firm price reflects the genuine value of an engineer in the building. A remote analysis would miss specialty equipment a walk-through catches. The price differential vs. automated providers is real value, not just labor overhead. This is the segment where major firms compete legitimately on quality, not just on engagement structure.
For residential and typical small-commercial, on-site engineering doesn't capture details that aren't already in public data plus RSMeans. The structured-data approach produces the same MACRS classification result. The price differential vs. major firms is essentially labor-arbitrage, not quality.
ROI math at each tier
The most useful way to think about cost-seg pricing is as a percentage of Year-1 federal savings. The lower the percentage, the better the tier fits your property.
| Property scenario | Yr-1 fed savings (37%, 100% bonus) | CSS price | Mid-tier price | Major-firm price | CSS as % of savings | Major as % of savings |
|---|---|---|---|---|---|---|
| $250K LTR | $11,400 | $495 | $3,500 | ~$5,000+ | 4.3% | 44%+ |
| $500K STR | $36,500 | $795 | $5,000 | ~$5,000+ | 2.2% | 14% |
| $750K STR | $54,700 | $895 | $6,000 | ~$5,500 | 1.6% | 10% |
| $1.5M MF 2-4 | $87,000 | $1,395 | $6,500 | $8,000 | 1.6% | 9.2% |
| $3M Commercial | $185,000 | $1,895 | $7,500 | $12,000 | 1.0% | 6.5% |
| $10M Hospitality | $650,000+ | N/A (out of scope) | $15,000 | $25,000 | N/A | 3.8% |
Year-1 savings assumptions: 19% reclassification for LTR, 27% for STR, 22% for typical commercial, 100% bonus depreciation per OBBBA, 37% federal bracket. Land allocation: 22% residential, 25% STR, 25% commercial. Actual results vary by property specifics.
Reading the table: at $250K residential, the major-firm tier consumes 44%+ of Year-1 savings — the math doesn't pencil. At $10M hospitality, the major-firm tier consumes only 3.8% of Year-1 savings, and the on-site engineering produces measurably better classification accuracy. The tier choice should match property value: low-value properties to automated providers, high-value commercial to major firms.
Geographic and state variation
US cost-segregation pricing does not vary by state. Providers are national, and RSMeans cost data is regionally adjusted within the engine itself rather than via differential pricing. A $750K STR in Pacific Beach is priced the same way at the same provider as a $750K STR in East Austin or Park City.
What does vary by state is the underlying tax math, which affects the value of the study (not its price):
- California, New York, New Jersey, others: partial or full decoupling from federal bonus depreciation. State return runs straight-line on a parallel schedule. Federal Year-1 savings are unchanged; state schedule requires extra workpaper.
- Texas, Nevada, Florida, Tennessee, and other no-income-tax states: federal Year-1 savings are the entire Year-1 benefit. No state schedule complexity.
- Arizona: conforms to federal bonus depreciation and has a flat 2.5% state rate (lowest in any state with income tax). Federal and state Year-1 savings align cleanly.
- Most other states with income tax: generally conform to federal bonus depreciation with state-specific addbacks for some classes. Confirm with your CPA.
How to choose your provider tier
The decision tree, in order:
- Is the property over $5M with specialty assets, hospitality, or ground-up commercial? → Major firm.
- Is the property mid-market commercial $1M–$5M with non-public construction details? → Mid-tier traditional.
- Otherwise (residential, STR, small MF, small commercial under $5M, or you want fast and affordable)? → Automated provider (Cost Seg Smart) or DIY software (KBKG Residential Cost Segregator) at the same price point.

Frequently asked
How much does a cost segregation study cost in 2026?
US cost segregation pricing in 2026 ranges from $495 to $15,000+ — a 30× spread for studies that produce comparably defensible reports. The market has stratified into three tiers: automated and DIY providers ($495–$2,995) for residential and small-commercial under $5M; mid-tier traditional firms ($3,000–$8,000) for mid-market commercial $1M–$5M; major engineering firms ($5,000–$15,000+) for $5M+ commercial with specialty assets and on-site engineering.
Why is there such a wide price range for cost segregation?
The price spread reflects the labor model, not the methodology. Every credible firm uses the same RSMeans 2024 cost data, MACRS classification per Rev. Proc. 87-56, and IRS Cost Segregation Audit Techniques Guide (Pub 5653) framework. Where firms differ is whether they send an engineer on-site (4–8 weeks, $5,000–$15,000), run a hybrid mid-tier engagement ($3,000–$8,000), or apply the same methodology to structured property data automatically ($495–$2,995, under 60 minutes). For most residential and small-commercial properties, the structured-data approach produces the same defensible result.
Are cheap cost segregation studies legitimate?
Yes, when they apply the same engineering methodology. The IRS does not differentiate by price or vendor — it evaluates studies against 13 quality elements in Pub 5653. Automated providers (Cost Seg Smart) and DIY software (KBKG Residential Cost Segregator) at the $495–$799 price point produce reports that address each ATG quality element with documentation traceable to RSMeans, Pub 946, and Rev. Proc. 87-56. The price reflects delivery model (structured data vs. on-site engineering) rather than report quality.
What's the average cost of a cost segregation study for a residential rental?
For residential rentals in 2026, the median price varies by tier: automated providers $495–$1,295 (under $1M residential) or $1,595–$1,895 ($1M–$5M); mid-tier traditional firms $3,000–$8,000; major firms typically don't quote sub-$5M residential, but when they do, $5,000+ is the floor. For a typical $500K rental, expect $795 (automated/Cost Seg Smart), $499 (DIY/KBKG Residential), $3,000–$6,000 (mid-tier ELB/CSSI/Bedford), or $5,000+ (major KBKG/ETS/Madison SPECS).
What's the average cost of a cost segregation study for commercial property?
For commercial property in 2026, median prices: $1,395–$1,895 for automated providers on $1M–$5M commercial; $4,000–$8,000 for mid-tier traditional firms on $1M–$5M; $8,000–$15,000+ for major firms on $5M+ commercial with on-site engineering. Above $15M with specialty assets, custom commercial pricing typically runs $15K–$50K depending on complexity.
Does paying more for a cost segregation study get me better tax savings?
Generally no — the methodology is shared across credible firms and produces comparable MACRS classification. What you pay more for is on-site engineering judgment that captures details a remote analysis can miss; this matters specifically for $5M+ commercial properties with specialty assets, custom MEP, hospitality build-out, or ground-up new construction. For residential and typical small-commercial under $5M, structured-data analysis produces the same accelerated allocation result. Paying $5,000 instead of $795 for a $500K STR doesn't increase your Year-1 federal savings — it just changes the labor model behind the same defensible report.
How much should I expect to pay for cost segregation in California, Texas, or New York?
Cost segregation pricing in 2026 does not vary by state — the providers are national, RSMeans cost data is regionally adjusted within the engine itself, and most firms quote based on property value and complexity rather than location. A $750K STR in San Diego, Austin, or Manhattan is priced the same way at the same provider. What does vary by state is the underlying tax math: California decouples from federal bonus depreciation (so Year-1 state savings differ); Texas and Nevada have no state income tax (federal benefit is the whole benefit); New York largely conforms but with state-specific addbacks for some classes. The cost-seg study fee is national; the tax outcome is jurisdiction-specific.
Can I get a cost segregation study for under $500?
Yes. Cost Seg Smart's $495 tier applies to residential properties (single-family rental, short-term rental, condo) under $300,000 purchase price. KBKG Residential Cost Segregator (DIY software) prices comparably at around $499 per property but transfers the labor and audit-defense responsibility to the customer. Below $495, the only options are full-DIY spreadsheet approaches without engineer attestation, which we don't recommend for any property where audit defense matters.
